Background: In high-risk and frail patients with multivessel coronary artery disease (MV CAD), guidelines indicated complete revascularization with or without the use of cardiopulmonary bypass (CPB) bears a high morbidity and mortality risk. In cases where catheter interventions were deemed unsuitable and conventional coronary artery bypass grafting (CABG) posed an unacceptable perioperative risk, patients were scheduled for minimally invasive direct coronary artery bypass (MIDCAB) grafting or minimally invasive multivessel coronary artery bypass grafting (MICS-CABG). We called this approach “palliative revascularization.” This study assesses the safety and impact of palliative revascularization on clinical outcomes and overall survival. Methods: A consecutive series of 57 patients undergoing MIDCAB or MICS-CABG as a palliative surgery between 2008 and 2018 was included. The decision for palliative surgery was met in heart team after carefully assessing each case. The patients underwent single or double-vessel revascularization using the left internal thoracic artery and rarely radial artery/saphenous vein segments, both endoscopically harvested. Inpatient data could be completed for all 57 patients. The mean follow-up interval was 4.2 ± 3.7 years, with a follow-up rate of 91.2%. Results: Mean patient age was 79.7 ± 7.4 years. Overall, 46 patients (80.7%) were male, 26 (45.6%) had a history of atrial fibrillation and 25 (43.9%) of chronic kidney disease. In total, 13 patients exhibited a moderate EuroSCORE II, while 27 were classified as high risk, with a EuroSCORE II exceeding 5%. Additionally, 40 patients (70.2%) presented with three-vessel disease, 17 (29.8%) suffered an acute myocardial infarction within three weeks prior to surgery and 50.9% presented an impaired ejection fraction. There were 48 MIDCAB and nine MICS CABG with no conversions either to sternotomy or to CPB. Eight cases were planned as hybrid procedures and only 15 patients (26.3%) were completely revascularized. During the first 30 days, four patients (7%) died. A myocardial infarction occurred in only one case, no patient necessitated immediate reoperation. The one-, three- and five-year survival rates were 83%, 67% and 61%, respectively. Conclusions: MIDCAB and MICS CABG can be successfully conducted as less invasive palliative surgery in high-risk multimorbid patients with MV CAD. The early and mid-term results were better than predicted. A higher rate of hybrid procedures could improve long-term outcome in selected cases. Full article

Background/Objectives: Acute kidney injury (AKI) is a common and severe complication in patients with acute myocardial infarction (AMI). Very elderly patients are at a heightened risk of developing AKI. Fibrinogen and albumin are well-known biomarkers of inflammation and nutrition, which are highly related to AKI. We aim to explore the predictive value of the fibrinogen-to-albumin ratio (FAR) for AKI in very elderly patients with AMI. Methods: A retrospective cohort of AMI patients ≥ 75 years old hospitalized at the First Affiliated Hospital of Xi’an Jiaotong University between January 2018 and December 2022 was established. Clinical data and medication information were collected through the biospecimen information resource center at the hospital. Univariate and multivariable logistic regression models were used to analyze the association between FAR and the risk of AKI in patients with AMI. FAR was calculated as the ratio of fibrinogen (FIB) to serum albumin (ALB) level (FAR = FIB/ALB). The primary outcome is acute kidney injury, which was diagnosed based on KDIGO 2012 criteria. Results: Among 1236 patients enrolled, 66.8% of them were male, the median age was 80.00 years (77.00–83.00), and acute kidney injury occurred in 18.8% (n = 232) of the cohort. Comparative analysis revealed significant disparities in clinical characteristics between patients with or without AKI. Patients with AKI exhibited a markedly higher prevalence of arrhythmia (51.9% vs. 28.1%, p < 0.001) and lower average systolic blood pressure (115.77 ± 25.96 vs. 122.64 ± 22.65 mmHg, p = 0.013). In addition, after adjusting for age, sex, history of hypertension, left ventricular ejection fraction (LVEF), and other factors, FAR remained an independent risk factor for acute kidney injury (OR = 1.47, 95%CI: 1.36–1.58). ROC analysis shows that FAR predicted stage 2–3 AKI with superior accuracy (AUC 0.94, NPV 98.6%) versus any AKI (AUC 0.79, NPV 93.0%), enabling risk-stratified management. Conclusions: FAR serves as both a high-sensitivity screening tool for any AKI and a high-specificity sentinel for severe AKI, with NPV-driven thresholds guiding resource allocation in the fragile elderly.

Background/Objectives: Acute kidney injury (AKI) worsens outcomes in COPD exacerbation (COPDe), yet limited data compare the demographics and mortality risk factors of COPDe admissions with and without AKI. Understanding this association may enhance risk stratification and management strategies. The aim of this study was to identify demographic differences and mortality risk factors in COPDe admissions with and without AKI. Methods: We conducted a retrospective cohort study using the National Inpatient Sample (NIS) from 1 January 2016 to 1 January 2021. Patients aged ≥ 35 years with a history of smoking and a diagnosis of COPDe were included. Patients with CKD stage 5, end-stage kidney disease (ESKD), heart failure decompensation, urinary tract infections, myocardial infarction, alpha-1 antitrypsin deficiency, or active COVID-19 infection were excluded. Baseline demographics were analyzed using descriptive statistics. Multivariate logistic regression analysis was used to measure the odds ratio (OR) of mortality. Statistical analyses were conducted using IBM SPSS Statistics V.30, with statistical significance at p < 0.05. Results: Among 405,845 hospitalized COPDe patients, 13.6% had AKI. These patients were older, had longer hospital stays, and included fewer females and White patients. AKI was associated with significantly higher mortality (OR: 2.417), more frequent acute respiratory failure (OR: 4.559), intubation (OR: 10.262), and vasopressor use (OR: 2.736). CVA, pneumonia, and pulmonary hypertension were significant mortality predictors. Hypertension, CAD, and diabetes were associated with lower mortality. Conclusions: AKI in COPDe admissions is associated with worse outcomes. Protective effects from certain comorbidities may relate to renoprotective medications. Study limitations include coding errors and retrospective design. Full article

Peripheral artery disease (PAD) is associated with an elevated risk of major adverse cardiovascular events (MACE). Despite this, few reliable biomarkers exist to identify patients at heightened risk of MACE. Growth differentiation factor 15 (GDF15), a stress-responsive cytokine implicated in inflammation, atherosclerosis, and thrombosis, has been broadly studied in cardiovascular disease but remains underexplored in PAD. This study aimed to evaluate the prognostic utility of GDF15 for predicting 2-year MACE in PAD patients using explainable statistical and machine learning approaches. We conducted a prospective analysis of 1192 individuals (454 with PAD and 738 without PAD). At study entry, patient plasma GDF15 concentrations were measured using a validated multiplex immunoassay. The cohort was followed for two years to monitor the occurrence of MACE, defined as stroke, myocardial infarction, or death. Baseline GDF15 levels were compared between PAD and non-PAD participants using the Mann–Whitney U test. A machine learning model based on extreme gradient boosting (XGBoost) was trained to predict 2-year MACE using 10-fold cross-validation, incorporating GDF15 and clinical variables including age, sex, comorbidities (hypertension, diabetes, dyslipidemia, congestive heart failure, coronary artery disease, and previous stroke or transient ischemic attack), smoking history, and cardioprotective medication use. The model’s primary evaluation metric was the F1 score, a validated measurement of the harmonic mean of the precision and recall values of the prediction model. Secondary model performance metrics included precision, recall, positive likelihood ratio (LR+), and negative likelihood ratio (LR-). A prediction probability histogram and Shapley additive explanations (SHAP) analysis were used to assess model discrimination and interpretability. The mean participant age was 70 ± SD 11 years, with 32% (n = 386) female representation. Median plasma GDF15 levels were significantly higher in PAD patients compared to the levels in non-PAD patients (1.29 [IQR 0.77–2.22] vs. 0.99 [IQR 0.61–1.63] pg/mL; p < 0.001). During the 2-year follow-up period, 219 individuals (18.4%) experienced MACE. The XGBoost model demonstrated strong predictive performance for 2-year MACE (F1 score = 0.83; precision = 82.0%; recall = 83.7%; LR+ = 1.88; LR− = 0.83). The prediction histogram revealed distinct stratification between those who did vs. did not experience 2-year MACE. SHAP analysis identified GDF15 as the most influential predictive feature, surpassing traditional clinical predictors such as age, cardiovascular history, and smoking status. This study highlights GDF15 as a strong prognostic biomarker for 2-year MACE in patients with PAD. When combined with clinical variables in an interpretable machine learning model, GDF15 supports the early identification of patients at high risk for systemic cardiovascular events, facilitating personalized treatment strategies including multidisciplinary specialist referrals and aggressive cardiovascular risk reduction therapy. This biomarker-guided approach offers a promising pathway for improving cardiovascular outcomes in the PAD population through precision risk stratification. Full article

Background/Objectives: Patients with peripheral artery disease (PAD) have a heightened risk of major adverse cardiovascular events (MACE), including myocardial infarction, stroke, and death. Despite this, limited progress has been made in identifying reliable biomarkers to prognosticate such outcomes. Circulating growth factors, known to influence endothelial function and the progression of atherosclerosis, may hold prognostic value in this context. The objective of this research was to evaluate a broad range of blood-based growth factors to investigate their potential as predictors of MACE in patients diagnosed with PAD. Methods: A total of 465 patients with PAD were enrolled in a prospective cohort study. Baseline plasma levels of five different growth factors were measured, and participants were monitored over a two-year period. The primary outcome was the occurrence of MACE within those two years. Comparative analysis of protein levels between patients who did and did not experience MACE was performed using the Mann–Whitney U test. To assess the individual prognostic significance of each protein for predicting MACE within two years, Cox proportional hazards regression was performed, adjusting for clinical and demographic factors including a history of coronary and cerebrovascular disease. Subgroup analysis was performed to assess the prognostic value of these proteins in females, who may be at higher risk of PAD-related adverse events. Net reclassification improvement (NRI), integrated discrimination improvement (IDI), and area under the receiver operating characteristic curve (AUROC) were calculated to assess the added value of significant biomarkers to model performance for predicting 2-year MACE when compared to using demographic/clinical features alone. Kaplan–Meier curves stratified by IGFBP-1 tertiles compared using log-rank tests and Cox proportional hazards analysis were used to assess 2-year MACE risk trajectory based on plasma protein levels. Results: The average participant age was 71 years (SD 10); 31.1% were female and 47.2% had diabetes. By the end of the two-year follow-up, 18.1% (n = 84) had experienced MACE. Of all proteins studied, only insulin-like growth factor-binding protein 1 (IGFBP-1) showed a significant elevation among patients who suffered MACE versus those who remained event-free (20.66 [SD 3.91] vs. 13.94 [SD 3.80] pg/mL; p = 0.012). IGFBP-1 remained a significant independent predictor of 2-year MACE occurrence in the multivariable Cox analysis (adjusted hazard ratio [HR] 1.57, 95% CI 1.21–1.97; p = 0.012). Subgroup analyses revealed that IGFBP-1 was significantly associated with 2-year MACE occurrence in both females (adjusted HR 1.52, 95% CI 1.16–1.97; p = 0.015) and males (adjusted HR 1.04, 95% CI 1.02–1.22; p = 0.045). Incorporating IGFBP-1 into the clinical risk prediction model significantly enhanced its predictive performance, with an increase in the AUROC from 0.73 (95% CI 0.71–0.75) to 0.79 (95% CI 0.77–0.81; p = 0.01), an NRI of 0.21 (95% CI 0.07–0.36; p = 0.014), and an IDI of 0.041 (95% CI 0.015–0.066; p = 0.008), highlighting the prognostic value of IGFBP-1. Kaplan–Meier analysis showed an increase in the cumulative incidence of 2-year MACE across IGFBP-1 tertiles. Patients in the highest IGFBP-1 tertile experienced a significantly higher event rate compared to those in the lowest tertile (log-rank p = 0.008). In the Cox proportional hazards analysis, the highest tertile of IGFBP-1 was associated with increased 2-year MACE risk compared to the lowest tertile (adjusted HR 1.81; 95% CI: 1.31–2.65; p = 0.001). Conclusions: Among the growth factors analyzed, IGFBP-1 emerged as the sole biomarker independently linked to the development of MACE over a two-year span in both female and male PAD patients. The addition of IGFBP-1 to clinical features significantly improved model predictive performance for 2-year MACE. Measuring IGFBP-1 levels may enhance risk stratification and guide the intensity of therapeutic interventions and referrals to cardiovascular specialists, ultimately supporting more personalized and effective management strategies for patients with PAD to reduce systemic vascular risk.

Background and Objectives: Stress and type A personality are known to be risk factors for the development of acute myocardial infarction (AMI), and depression is both a risk factor for AMI and a prognostic factor. In this study, we aimed to evaluate the relationship between psychological flexibility, perceived stress level, depression, and anxiety in AMI patients. Material and Methods: The study included 89 patients with a diagnosis of AMI and 89 volunteer participants with no previous history of coronary angiography and no diagnosis of AMI. Patients were evaluated with the Acceptance and Action Questionnaire (AAQ)-II, the Hospital Anxiety and Depression Scale (HADS), and the Perceived Stress Scale (PSS)-14. Results: A strong positive statistically significant correlation was found between the Perceived Stress Scale score and HAD-II (r = 0.697 p < 0.001), HAD-Anxiety (r = 0.715 p < 0.001), and HAD-Depression (r = 0.657 p < 0.001) scores. A statistically significant moderate positive correlation was found between the HAD-Depression Scale and HAD-Anxiety (r = 0.593 p < 0.001) and AAQ-II (r = 0.530 p < 0.001) scores. A strong positive statistically significant correlation was found between the HAD-Anxiety Scale and AAQ-II (r = 0.809 p < 0.001) scores. Conclusions: Investigation of psychological flexibility, anxiety, and depression in AMI patients with scales such as AAQ-II, PSS-14, and HADS may help early diagnosis and treatment of individuals at risk for psychiatric disorders.

Cardiovascular diseases continue to pose a major global health burden, contributing significantly to mortality rates worldwide. This study aimed to explore the association between myocardial infarction and basic hematological parameters—red blood cells (RBCs), white blood cells (WBCs), and platelets (PLTs)—which are routinely assessed in clinical diagnostics. The analysis was conducted on a cohort of 743 adults hospitalized with diagnosed cardiovascular conditions. To identify blood parameters that distinguish patients with a history of first-time myocardial infarction from those who had never experienced such an event, we employed a dual analytic approach. Standard parametric methods were complemented with bootstrap resampling to strengthen inference and mitigate the impact of sampling variability. Patients with myocardial infarction showed decreased RBC and elevated WBC counts relative to those without infarction. These associations were non-linear, with the most pronounced group differences observed within the second and third quartiles of RBC and WBC distributions, while minimal differences appeared at the distributional extremes. No significant differences were found in platelet count (PLT) between the groups. Bootstrap validation not only corroborated findings obtained through traditional statistics, but also enhanced the robustness of the results, providing improved estimates under data conditions prone to skewness or small sample artifacts. This approach enabled the detection of nuanced patterns that might elude classical inference. Our findings emphasize the utility of resampling techniques in clinical research settings, particularly where inference stability is critical. Incorporating such methods in future investigations may advance statistical rigor, increase reproducibility, and better capture complex biological relationships in medical datasets. Full article

Background/Objectives: Large clinical trials have established the optimal antiplatelet strategy in the wide spectrum of coronary artery disease. However, data are scarce regarding MINOCA and the aim of our study is to present data from the current clinical practice. Methods: A total of 151 patients were included in this study after exclusion of 27 patients with myocarditis and other diagnoses. A cardiac magnetic resonance (CMR) performed at 123/151 patients demonstrated an ischemic pattern of late gadolinium enhancement (LGE) confirming the diagnosis of true acute myocardial infarction (AMI) in 42 cases (28%). Based on multimodality imaging and clinical judgement, Takotsubo syndrome (TTS) was diagnosed in 55 patients (36%), whereas CMR failed to reveal abnormal findings in 54 cases (36%), categorized as MINOCA of unknown origin. Results: Regarding antithrombotic prescriptions at discharge, 38% of patients received dual antiplatelet (DAPT) or dual antithrombotic therapy (DAT, 1 antiplatelet plus 1 anticoagulant), 49.7% received single antiplatelet (SAPT) or anticoagulant, and 12% received no antithrombotic treatment. Univariate analysis showed that the likelihood of prescribing DAPT or DAT was associated with left ventricular ejection fraction (LVEF) (r = 0.202, p = 0.013), atherosclerotic lesions on coronary angiography (r = 0.303, p < 0.001), prior use of anticoagulants (r = −0.258, p = 0.001), and marginally with the INTERTAK score (r = −0.198, p = 0.044). A multivariable model, adjusted for age, LVEF, ECG abnormalities, and history of anticoagulant use, confirmed the independent association between angiographic evidence of atherosclerosis and the decision for DAPT/DAT (OR: 0.334, 95% CI: 0.307–0.813, p < 0.001). However, the initial treatment decision did not seem to impact 2-year prognosis in our population. Conclusions: Our study results reveal that decision making in the antithrombotic strategy for MINOCA patients poses a challenge in clinical practice. More robust data are required for definite conclusions on the prognostic implications. Full article

Background: Acute mesenteric ischemia (AMI) is a potentially life-threatening condition that requires prompt diagnosis and treatment. The presence of air within the arterial lumen, particularly in the abdomen, is an uncommon finding with varied etiologies. This case report presents a unique instance of AMI with air in the superior mesenteric artery (SMA), highlighting the complexities in diagnosis and management. Case presentation: An 89-year-old male with a history of smoking, hypertension, dyslipidemia, and atrial fibrillation presented with chest pain and underwent coronary angiography for suspected anterior ST-elevation myocardial infarction (STEMI). Following successful thromboaspiration and admission to the coronary care unit, he developed severe abdominal pain. A contrast-enhanced computed tomography (CECT) scan revealed a thromboembolic occlusion in the SMA, along with air filling in the SMA and its branches. An endovascular thrombectomy was performed, but the patient died the next day due to complications related to AMI and metabolic acidosis. Conclusions: This case underscores the challenges in diagnosing and managing AMI, particularly when accompanied by unusual imaging findings such as air within the SMA. The presence of air in the arterial system raises questions about its origin and clinical significance in the context of AMI. Further research is needed to understand the mechanisms and implications of this rare phenomenon, which may have implications for refining diagnostic and therapeutic strategies for AMI. Full article

Health beliefs, disease acceptance, and self-efficacy significantly influence patients’ behavior. This study examined factors associated with self-efficacy and illness acceptance in patients with heart failure (HF). The study, conducted from June 2022 to June 2024, included 231 patients aged ≥ 65 years hospitalized for HF. Self-efficacy and illness acceptance were assessed using the Generalized Self-Efficacy Scale (GSES) and Acceptance of Illness Scale (AIS). The median age of participants was 80 years (72–86); a total of 63.6% were women. The AIS score median was 25, indicating moderate disease acceptance, while the GSES score median was 30, reflecting relatively high self-efficacy. Lower GSES scores were associated with a history of cancer (p = 0.002) and geriatric depression (p = 0.000). Poor illness acceptance was linked to prior myocardial infarction (p = 0.020), atrial fibrillation (p = 0.008), stroke (p = 0.040), depression (p = 0.000), and frailty (p = 0.000). Frailty (OR 0.81) and cancer history (OR 3.08) independently predicted self-efficacy, while lower illness acceptance was linked to older age (OR 0.95), stressful events (OR 0.53), stroke (OR 0.26), and improved by physical activity (OR 1.22). Our results indicated that older HF patients exhibit high self-efficacy but moderate illness acceptance. Self-efficacy is influenced by frailty and cancer history, while illness acceptance by age, stress, stroke, and physical activity. Full article

Background: Popliteal venous aneurysms (PVA) are an uncommon but potentially severe condition due to their association with increased risk of recurrent pulmonary embolisms. Because of their rarity, their aetiology, natural history, and optimal treatment strategies have been poorly defined. The aim of this paper is to report a comprehensive systematic review on the treatment strategies and outcomes in PVA, summarizing current evidence. Methods: A systematic literature search was conducted in PubMed, Scopus, and Web of Science, covering studies published from database inception through February 2025 (protocol registered on PROSPERO CRD420251008927). The primary endpoint was the analysis of outcomes and complications associated with surgical and conservative management. Results: Nine studies, including 173 adult patients with popliteal venous aneurysms, were included. The mean age was 56 years (range 18–86 years, mean aneurysm diameter 25.4 mm). Most of the patients were female (73, 42.2%). Overall, 85 (49.1%) aneurysms were saccular and 74 (42.8%) fusiform, although morphology was not consistently reported across all studies. Intraluminal thrombus was reported in 26 cases (15.0%), and pulmonary embolism upon presentation in 21 (12.1%). Surgical treatment was performed in 119 patients (68.8%), while 54 (31.2%) were managed conservatively. Fifteen patients (13.0%) experienced postoperative complications, including wound infections (4, 3.5%), hematomas (7, 6.0%), and nerve injury (4, 3.5%), but no cases of postoperative pulmonary embolisms were observed. Following surgery, anticoagulation was indicated in most cases for 3–6 months or a long life. During follow-up (mean 35 months, range 1–262), thrombosis of the surgical reconstruction was observed in 1 patient (0.8%). Death occurred in 3 cases (5.5%), all in the non-surgical group: 2 (3.7%) due to malignancy and 1 (1.9%) from myocardial infarction. Conclusions: PVA is a rarely described condition potentially associated with the risk of PE. In their management, surgical strategies in association with oral anticoagulation represent the most commonly described approach, allowing for satisfactory results and a low rate of complications.

Background and Objectives: Screening, primary prevention, and the early identification of high-risk individuals are crucial for minimising the burden of cardiovascular diseases (CVDs). In this study, we aimed to evaluate the association of retinal microvascular features with myocardial dysfunction and CVD risk factors in a group of patients with significant coronary artery disease (CAD) compared to patients with newly diagnosed isolated arterial hypertension and healthy controls. Materials and Methods: We performed a single-centre cross-sectional study on 214 individuals divided into three groups: a group of 99 cases diagnosed with significant CAD, a group of 61 cases with newly diagnosed isolated arterial hypertension, and a control group of 54 cases with no confirmed cardiovascular pathology. Colour optic disc-centred retinal photographs were taken in all cases, and the following parameters were quantified using MONA REVA 3.0.0 software (VITO Health, Mol, Belgium): central retinal arteriolar equivalent, central retinal venular equivalent, arteriovenous ratio, fractal dimension, tortuosity index, and lacunarity. Univariable and multivariable statistical analyses were performed to assess changes in retinal microvascular features in CVD. Results: Dyslipidaemia (p = 0.009), systolic blood pressure (p = 0.008), and LDL cholesterol (p = 0.003) were negatively associated while left ventricular (LV) strain (0.043) was positively associated with the CRAE. In the case of the CRVE, the coronary Agatston score (p = 0.016) proved a positive and HDL cholesterol (p = 0.018) a negative association. A lower fractal dimension was associated with the presence of diabetes mellitus (p = 0.006), dyslipidaemia (p = 0.011), and a history of acute myocardial infarction (p = 0.018), while a higher fractal dimension was associated with increased left ventricular ejection fraction (LVEF) (p = 0.006) and medical treatment (p = 0.005). Lacunarity was higher in patients of female gender (p = 0.005), with decreased HDL (p = 0.014) and LVEF (0.005), and with increased age (p < 0.001) and Agatston score (p = 0.001). The vessel tortuosity index increased with LV strain (p = 0.05), medical treatment (p = 0.043), and male gender (p = 0.006). Conclusions: Retinal microvascular features may serve as additional risk stratification tools in patients with CVD, particularly CAD, pending prospective validation. Full article

Background: Models of second-phase cardiac rehabilitation (CR) following myocardial infarction (MI) differ across countries. The aim of this study was to compare outcomes in MI survivors participating in outpatient and inpatient CR programs. Methods: All patients hospitalized for acute MI in Poland between October 2017 and December 2018 (n = 96,634) were included in the study. Among them, 4411 patients were referred to and commenced outpatient CR, whereas 11,626 patients started inpatient CR within 30 days following discharge. Results: The mean follow-up period was 332.8 ± 128.1 days. Younger age, male sex, and a history of cancer were associated with a higher probability of participating in outpatient CR, whereas diabetes, heart failure, chronic kidney disease, chronic obstructive pulmonary disease, ST-elevation MI, and myocardial revascularization were associated with a lower likelihood of outpatient CR participation. Participation in outpatient CR was linked to a reduced risk of all-cause mortality, in both univariable (hazard ratio [95% confidence interval]: 0.37 [0.26–0.51]) and multivariable analyses (0.53 [0.38–0.74]). Outpatient CR was also associated with a lower risk of death, MI, or stroke (0.57 [0.48–0.67] in univariable analysis and 0.72 [0.61–0.84] in multivariable analysis), as well as a lower risk of death or cardiovascular hospitalization (0.78 [0.73–0.84] and 0.85 [0.80–0.91], respectively). Conclusions: Outpatient CR following MI tends to occur alongside a better prognosis compared to inpatient programs. Full article

Background: The etiology of acute myocardial infarction (AMI) in patients without history of standard modifiable risk factors (SMuRFs) remains unclear. Simultaneously, evidence suggests that mental health status (MHS) contributes to the pathogenesis of AMI and worsens its outcomes. Methods: This analysis of the prospective “Beyond-SMuRFs” (NCT05535582) study included 650 consecutive patients with AMI who had available data on self-reported MHS before AMI, calculated by the SF36-Questionnaire mental component summary (MCS). Poor MHS was defined as MCS ≤ 50. Multivariable logistic-regression and Cox-regression analyses were implemented to investigate poor MHS as a potential predictor of SMuRF-less AMIs and compare all-cause mortality based on SMuRF-less and MH status, respectively. Results: Of 650 patients with AMI (mean age 62.6 ± 12.1 years), 288 (44.3%) had MCS ≤ 50 and 128 (19.7%) were SMuRF-less patients. Three out of four SMuRF-less patients reported an MCS ≤ 50 (n = 96, 75%), a significantly higher percentage than the corresponding percentage in patients with SMuRFs (n = 192, 36.8%; p < 0.01). The multivariable logistic regression model showed that MCS ≤ 50 was an independent predictor of SMuRF-less AMI [aOR = 0.95; 95% CI (0.94–0.96)]. Time-to-event analysis for all-cause mortality showed that patients with MCS > 50 had lower mortality rates than those with poor MHS (aHR, 3.61 [95% CI, 2.02 to 6.43], p < 0.01). Higher risk for all-cause mortality was also observed in SMuRF-less patients with poor MHS compared to patients with at least one SMuRF and good MHS [aHR, 4.52 (95% CI, 0.94–21.73)]. Conclusions: Poor MHS was an independent predictor of the occurrence of SMuRF-less AMI and predictive of higher mortality in patients with and without SMuRFs. Full article

Background: The one-year mortality risk for elderly patients undergoing proximal femur fracture repair surgery is three to four times higher compared to the general population. Other than time to surgery, risk factors for postoperative morbidity and mortality following surgery are poorly understood in the elderly. We sought to identify risk factors associated with morbidity and mortality in geriatric patients by anticoagulation status undergoing hip fracture repair. Methods: Patients aged ≥65 years undergoing surgery for hip fracture repair were included (2009–2019) from a US-based hip fracture registry. Factors associated with 90-day mortality were determined using multivariable logistic regression and stratified by antithrombotic agent medication use prior to surgery. Direct oral anticoagulation (DOAC) medications were the largest group, and all antithrombotic agents were included in the delineation. Results: A total of 35,463 patients were identified, and 87.1% (N = 30,902) were DOAC-naïve. Risk factors for 90-day mortality in DOAC-naïve patients were an American Society of Anesthesiologist’s (ASA) classification ≥3 (odds ratio [OR] = 2.56, 95% confidence interval [CI] = 2.24–2.93), preoperative myocardial infarction (OR = 1.87, 95% CI = 1.33–2.64), male gender (OR = 1.73, 95% CI = 1.59–1.88), congestive heart failure (CHF) (OR = 1.64, 95% CI = 1.50–1.80), psychoses (OR = 1.27, 95% CI = 1.15–1.42), renal failure (OR = 1.29, 95% CI = 1.19–1.40), smoking history (OR = 1.19, 95% CI = 1.09–1.29), chronic pulmonary disease (OR = 1.14, 95% CI = 1.05–1.25), increasing age (OR = 1.07, 95% CI = 1.06–1.07), and decreasing body mass index (BMI) (OR = 1.06, 95% CI = 1.05–1.08). Identified factors for mortality in the DOAC group also included ASA classification ≥3 (OR = 2.15, 95% CI = 1.44–3.20), male gender (OR = 1.68, 95% CI = 1.41–2.01), CHF (OR = 1.45, 95% CI = 1.22–1.73), chronic pulmonary disease (OR = 1.34, 95% CI = 1.12–1.61), decreasing BMI (OR = 1.04, 95% CI = 1.02–1.06), and increasing age (OR = 1.02, 95% CI = 1.01–1.03). Conclusions: Regardless of preoperative DOAC status, ASA classification, gender, CHF, chronic pulmonary disease, lower BMI, and higher age are associated with an increased risk of mortality. Some of these comorbidities can be utilized for risk stratification prior to surgery. Full article
