Background: Despite its high prevalence, little is known about the effect of sex on the management and outcomes of aortic stenosis (AS). We sought to characterize the effect of sex on the clinical evaluation for and provision of aortic valve replacement (AVR), including surgical (SAVR) and transcatheter aortic valve replacement (TAVR), and the subsequent morbidity and mortality outcomes. Methods: A comprehensive chart review was conducted on all patients with a first diagnosis of severe aortic stenosis (AS) at Vancouver General and University of British Columbia hospitals from 2012 to 2022. Exact chi-square and Kruskal–Wallis tests were used to evaluate the variables of interest. Results: A total of 1794 studies met the inclusion criteria, comprising 782 females (44%) and 1012 males (56%). Females were significantly older than males at the time of the first diagnosis (79 versus 75 years, p < 0.001). Females were significantly less likely to be evaluated by the TAVR clinic or cardiac surgeon or to receive aortic valve intervention (p-value ≤ 0.001). Females were significantly more likely to be rejected for TAVR due to older age (OR 0.23 (0.07, 0.59)), comorbid conditions (OR 0.68 (0.47, 0.97)), and frailty (OR 0.23 (0.07, 0.59)). Females were significantly more likely to be rejected for SAVR on the basis of frailty (OR 0.66 (0.46, 0.94)). Females also had significantly higher rates of 1-year mortality, hospitalization, and heart failure hospitalization compared to males (p-values < 0.05). Conclusions: Our data suggest significant sex-based discrepancies in the management of AS. Females with severe AS are diagnosed later in life and are less likely to be evaluated for valve intervention. They are less likely to receive intervention due to older age, frailty, and multimorbid conditions. Further research is warranted for a more effective identification and follow up of aortic stenosis, as well as timely referral for AVR, where appropriate, especially for females. Full article

The management of acute heart failure (AHF) is becoming increasingly complex, especially in patients with multiple comorbidities. Endothelin-1 (ET-1), a vasoconstrictive peptide, is an important mediator of neurohormonal activation, endothelial dysfunction, and cardiac remodeling—key processes involved in the pathogenesis of AHF. The aim of our study was to evaluate the diagnostic and prognostic performance of ET-1 in multimorbid AHF patients, compared to established markers such as amino terminal pro B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin I (hs-cTnI). We conducted a single-center prospective study including 76 patients; 54 with AHF and 22 serving as controls. Upon admission, all patients underwent a comprehensive clinical, echocardiographic, and laboratory evaluation, including plasma ET-1 measurement using the enzyme-linked immunosorbent assay (ELISA) method. Receiver operating characteristic (ROC) curve and area under the curve (AUC) analysis were performed to assess the diagnostic and prognostic performance of ET-1 in comparison to NT-proBNP and hs-cTnI. ET-1 levels were considerably higher in AHF patients than in controls (p = 0.02), with an AUC of 0.954, showing comparable diagnostic accuracy with NT-proBNP (AUC = 0.997), alongside strong correlations with signs of systemic congestion, increased hospital stay, and ventricular dysfunction. ET-1 had the strongest predictive accuracy for in-hospital mortality (AUC = 0.781, p = 0.026), outperforming NT-proBNP and hs-cTnI. For 30-day mortality, ET-1 remained a reliable predictor (AUC = 0.784, p = 0.016). However, as the follow-up period extended to one year, its predictive power declined, confirming ET-1’s prognostic efficacy only for short-term outcomes. Moreover, ET-1 levels were not influenced by the presence of comorbidities, demonstrating its potential as an independent biomarker. Our findings support that ET-1 is a valuable biomarker for both diagnosis and short-term prognosis in the assessment of multimorbid AHF patients. Full article

Background: The recently updated definition of sepsis considers pathophysiologic mechanisms to guide initial therapy. Clearly, generalized recommendations for sepsis therapy may be limited by pre-existing multimorbidity in addition to sepsis-related multi-organ failure. In particular, a recommendation regarding fluid rescue therapy may require adequate cardiac function and/or the absence of sepsis-induced cardiomyopathy. In all sepsis patients with compromised cardiac function or sepsis-induced cardiomyopathy, a patient-specific therapy regimen is required to prevent pulmonary edema and early death. Similarly, in sepsis, acute kidney injury with or without pre-existing chronic kidney disease requires attention to be paid to excretory renal function to avoid hypervolemia-mediated acute heart failure. In addition, hyponatremia related to intravascular hypovolemia may be explained by vasopressin stimulation. However, hypothetically, vasopressin hyporesponsiveness may contribute to sepsis-related acute kidney injury. In this review, relevant cardiorenal pathomechanisms will be assessed in the context of sepsis therapy. Conclusions: In conclusion, therapy for sepsis with acute kidney injury has to take cardiac comorbidity, if present, into account. The extent to which vasopressin hyporesponsiveness aggravates sepsis-mediated hypovolemia and renal insufficiency should remain a subject of further study. Full article

(1) Background: As the burden of multimorbidity is increasing worldwide, little is known about its prevalence in Lithuania. We aimed to estimate the prevalence of chronic conditions and multimorbidity among Lithuanian adults and assess their impact on healthcare utilization. (2) Methods: A retrospective analysis of the Lithuanian National Health Insurance Fund database was performed in 2019. Multimorbidity was defined as having two or more chronic conditions. (3) Results: Of the Lithuanian population, 1,193,668 (51.5%) had at least one chronic condition, and 717,386 (31.0%) had multimorbidity. Complex multimorbidity (CM) was present in 670,312 (28.9%) patients, with 85.0% having complex cardiac multimorbidity (CCM) and 15.0% having complex non-cardiac multimorbidity (CNM). Multimorbidity increased with age, from 2% at age 18–24 to 77.5% at age 80 and above, and was more prevalent among women (63.3% vs. 36.7%, p < 0.001). One-third of multimorbid patients were hospitalized at least once per year, with half staying for a week or longer. CCM patients were more likely to be hospitalized, rehospitalized, and have more primary care visits (OR: 2.23, 1.60, 4.24, respectively, all p < 0.001). (4) Conclusions: Multimorbidity in Lithuania increases with age and affects women more. Chronic cardiovascular diseases contribute to a higher prevalence of multimorbidity and a more significant burden on the healthcare system. Full article

Background: Vitiligo is a pigmentation disorder that impacts approximately 0.5% to 2% of the global population. Growing interest surrounds the comorbidities associated with vitiligo. This study aimed to describe the socio-demographic characteristics of the patients with vitiligo in Aragón (Spain) and to investigate their associated comorbidities. Methods: A retrospective observational study was conducted using clinical data from individuals in the EpiChron Cohort (reference population of 1.3 million) who were diagnosed with vitiligo between 1 January and 31 December 2019. The prevalence of chronic comorbidities was calculated using logistic regression models, obtaining the odds ratio (OR) of each comorbidity (dependent variable) according to the presence or absence of vitiligo (independent variable). We used a cut-off point for a statistical significance of p-value < 0.05. Results: In total, 218 patients diagnosed with vitiligo were analyzed. The mean age was 44.0 years, and 56.42% were female. The largest proportion of patients (34.86%) were aged between 18 and 44 years. Among all vitiligo patients included, 71.5% presented multimorbidity, with an average of 3.21 diagnosed comorbidities. The conditions most frequently associated with vitiligo included thyroid disorders (OR: 3.01, p < 0.001), ocular and hearing abnormalities (OR: 1.54, p < 0.020), inflammatory skin disorders (OR: 2.21, p < 0.001), connective tissue diseases (OR: 1.84, p < 0.007), lower respiratory tract diseases (OR: 1.78, p < 0.014), urinary tract infections (OR: 1.69, p < 0.032), and cardiac arrhythmias (OR 1.84, p < 0.034). Conclusions: This research highlights the importance of understanding the broader health implications of vitiligo and provides a foundation for further exploration into the complex interplay between this dermatologic condition and a diverse range of comorbidities.

Background/Objectives: Population aging is a worldwide phenomenon and is often associated with multimorbidity and polypharmacy. Complex medication regimens are common among older adults and contribute to the occurrence of harmful health outcomes. Age is one of the main risk factors for cancer. This study aimed to determine and characterize the therapeutic complexity in older patients with cancer, and analyze the factors associated with high complexity and the impact of the oncological context. Methods: A cross-sectional study with patients aged ≥65 years with cancer was conducted in three hospitals in northern Portugal. Data collection was obtained using self-reports. The medication regimen complexity was assessed using the Medication Regimen Complexity Index (MRCI). Descriptive and association statistical analysis were performed. Logistic, linear, simple and multiple regression analysis were conducted, with and without automatic variable selection. Results: A total of 552 patients were included (median age, 71; IQR, 68–76). The mean MRCI before the oncological context was 18.67 (SD 12.60) and 27.39 (SD 16.67) after the oncological context, presenting a statistically significant difference in the values obtained (p < 0.001). An elevated complexity was significantly associated with polypharmacy, chronic diseases and with the administration of high-risk medications (p < 0.05). High MRCI values showed a relationship with the occurrence of potential drug interactions (p < 0.001). There was no relationship with the existence of cardiac risk comorbidity. Conclusions: This study demonstrated the existence of high therapeutic complexity in older patients with cancer, suggesting the need for intervention to prevent medication-related problems in this vulnerable population.

Objectives: To assess the prevalence of systemic pathologies associated with periodontal diseases to determine multimorbidity patterns and risk factors for periodontal care. Methods: A single-center cross-sectional study analyzed patient records from 1 January 2019 to 31 December 2021 at the Department of Periodontology, part of the Dental Service of a hospital-based dental school in Lyon, France. The anonymized data included patient-reported medical history (questionnaire) and billing for periodontal procedures. Data were compared between patients in the Department of Periodontology and from Other Departments of the Dental Service. The association between clinically relevant pathologies, as defined as multimorbidity, and admission in the Department of Periodontology were assessed with logistic regression. Prevalences between the Department of Periodontology and the Other Departments of the Dental Service were compared with chi-squared tests. Relationship among pathologies was described through correlation analysis. Statistical analyses were conducted using R software with a significance level set at p < 0.05. Results: This study included records of 20,945 patients in the Dental Service with 1205 periodontal procedures performed in the Department of Periodontology. Patients admitted for periodontal care were older and mostly female (p-value < 0.001). The most frequent systemic pathologies were hypertension and diabetes in the Department of Periodontology. Hypertension associated with diabetes was the most frequent multimorbidity pattern, while the most frequent triad of multimorbidity was hypertension/diabetes/cardiac rhythm disorders. Patients with diabetes had a 1.49 times higher likelihood of admission to the Department of Periodontology (OR = 1.49 [1.20; 1.86]), with age also being a significant risk factor but with a smaller effect size (OR = 1.02 [1.01; 1.03]). Conclusions: Within the limitations of this study, hypertension, diabetes, cardiac rhythm disorders, and chronic renal insufficiency were identified as prevalent multimorbidity in the Department of Periodontology. Multimorbidity including diabetes seems to constitute a risk factor requiring periodontal care. Full article

Chronic kidney disease (CKD) affects > 10% of the global adult population and significantly increases the risk of cardiovascular disease (CVD), which remains the leading cause of death in this population. The development and progression of CVD—compared to the general population—is premature and accelerated, manifesting as coronary artery disease, heart failure, arrhythmias, and sudden cardiac death. CKD and CV disease combine to cause multimorbid cardiorenal syndrome (CRS) due to contributions from shared risk factors, including systolic hypertension, diabetes mellitus, obesity, and dyslipidemia. Additional neurohormonal activation, innate immunity, and inflammation contribute to progressive cardiac and renal deterioration, reflecting the strong bidirectional interaction between these organ systems. A shared molecular pathophysiology—including inflammation, oxidative stress, senescence, and hemodynamic fluctuations characterise all types of CRS. This review highlights the evolving paradigm and recent advances in our understanding of the molecular biology of CRS, outlining the potential for disease-specific therapies and biomarker disease detection.

Critical care physicians are commonly faced with patients exhibiting atrial fibrillation (AF), a cardiac arrhythmia with multifaceted origins. Recent investigations shed light on the heterogeneity among AF patients by uncovering unique AF phenotypes, characterized by differing treatment strategies and clinical outcomes. In this retrospective study encompassing 9401 AF patients in an intensive care cohort, we sought to identify differences in average treatment effects (ATEs) across different patient groups. We extract data from the MIMIC-III database, use hierarchical agglomerative clustering to identify patients’ phenotypes, and assign them to treatment groups based on their initial drug administration during AF episodes. The treatment options examined included beta blockers (BBs), potassium channel blockers (PCBs), calcium channel blockers (CCBs), and magnesium sulfate (MgS). Utilizing multiple imputation and inverse probability of treatment weighting, we estimate ATEs related to rhythm control, rate control, and mortality, approximated as hourly and daily rates (%/h, %/d). Our analysis unveiled four distinctive AF phenotypes: (1) postoperative hypertensive, (2) non-cardiovascular mutlimorbid, (3) cardiovascular multimorbid, and (4) valvulopathy atrial dilation. PCBs showed the highest cardioversion rates across phenotypes, ranging from 11.6%/h (9.35–13.3) to 7.69%/h (5.80–9.22). While CCBs demonstrated the highest effectiveness in controlling ventricular rates within the overall patient cohort, PCBs and MgS outperformed them in specific phenotypes. PCBs exhibited the most favorable mortality outcomes overall, except for the non-cardiovascular multimorbid cluster, where BBs displayed a lower mortality rate of 1.33%/d [1.04–1.93] compared to PCBs’ 1.68%/d [1.10–2.24]. The results of this study underscore the significant diversity in ATEs among individuals with AF and suggest that phenotype-based classification could be a valuable tool for physicians, providing personalized insights to inform clinical decision making.

(1) Background and Objectives: Morbid obesity significantly increases the prevalence of comorbidities, such as heart disease, restrictive lung disease, stroke, diabetes mellitus and more. (2) Methods: Patients undergoing gastric sleeve surgery were divided into three groups with BMI between 30–34.9 kg/m² (Group I), 35–39.9 kg/m² (Group II), and over 40 kg/m² (Group III). Preoperative examinations included cardiac ultrasound, respiratory function and laboratory tests, and preoperative comorbidities were also recorded. Following a one-year follow-up, we compared the rate of weight loss in the three groups at six months and one year following surgery, specifically, the effect of surgery on preoperative comorbidities at one year. (3) Results: The weight loss surgeries performed were successful in all three groups. Preoperative laboratory examinations, an echocardiogram and respiratory function results showed no clinically significant difference, except moderate elevations in blood lipid levels. Hypertension was the most common comorbidity. (4) Conclusions: In our patient population, hypertension and diabetes were the only comorbidities with a high prevalence. It can be explained by the relatively younger age among the patients (mean age 44.5 years) and the fact that they had not yet developed the pathological consequences of severe obesity. Consequently, while performing the surgery at a relatively younger age, it seems far more likely that the patient will return to a more active and productive life and enjoy a better quality of life. Additionally, the perioperative risk is lower, and the burden upon health systems and health expenditure is reduced by preventing comorbidities, in particular, multimorbidity. On this basis, it may be advisable to direct patients who do not exhaust the classical indications for bariatric surgery toward the surgical solution at a younger age. Our results suggest it is not worth waiting for comorbidities, especially multimorbidity, to appear. Full article

Pharmacokinetic and pharmacodynamic changes associated with old age, along with multimorbidity and polypharmacy might lead to inappropriate prescribing and adverse reactions. Explicit criteria such as the Screening tool of older people’s prescribing (STOPP) are useful to identify potential inappropriate prescribing’s (PIPs). Our retrospective study included discharge papers from patients aged ≥65 years, from an internal medicine department in Romania (January–June 2018). A subset of the STOPP-2 criteria was used to assess the prevalence and characteristics of PIPs. Regression analysis was performed to evaluate the impact of associated risk factors (i.e., age, gender, polypharmacy and specific disease). Out of the 516 discharge papers analyzed, 417 were further assessed for PIPs. Patients’ mean age was 75 years, 61.63% were female and 55.16% had at least one PIP, with 81.30% having one or two PIPs. Antithrombotic agents in patients with significant bleeding risk was the most prevalent PIP (23.98%), followed by the use of benzodiazepines (9.11%). Polypharmacy, extreme (>10 drugs) polypharmacy, hypertension and congestive heart failure were found as independent risk factors. PIP was prevalent and increased with (extreme) polypharmacy and specific cardiac disease. Comprehensive criteria like STOPP should be regularly used in clinical practice to identify PIPs to prevent potential harm. Full article

Objective: Advanced age is a risk factor in cardiac surgery contributing significantly to a worse outcome. The reasons are frailty and multimorbidity. In this study, we asked: Is there an aging of the heart which differs from chronological age? Methods: Propensity score matching was performed between 115 seniors ≥ 80 years and 345 juniors < 80 years. After the patients were found to be comparable in terms of cardiac and noncardiac disease and risk profiles, they were further analyzed for cardiac parameters. In addition, the seniors and juniors were compared in terms of cardiac health and postoperative outcome. Furthermore, the patients were subdivided into several age groups (<60 years, 60–69 years, 70–79 years, and >80 years) and compared regarding outcome. Results: The seniors demonstrated significantly lower tricuspid annular plane systolic excursion (TAPSE), significantly more frequent diastolic dysfunction, significantly higher plasma levels of NT-proBNP, and significantly larger left ventricular end-diastolic and end-systolic diameters and left atrial diameters (p < 0.001, respectively). Furthermore, in-hospital mortality and most postoperative complications were significantly higher in seniors compared with juniors. While old cardiac healthy patients showed better outcome than old cardiac aged patients, the outcome from young cardiac aged patients was better than old cardiac aged patients. The outcome and survival deteriorated with increasing life decades. Conclusions: The elderly suffer significantly more from cardiac deterioration, i.e., cardiac aging, and show higher multimorbidity. Mortality risk is significantly higher and they suffer more often from a complicated postoperative course compared to younger patients. Further approaches to prevention and treatment of cardiac aging are needed to address the needs of an aging society. Full article

Coronary artery disease (CAD) remains a leading cause of mortality and morbidity worldwide, and it is associated with considerable economic burden. In an ageing, multimorbid population, it has become increasingly important to develop reliable, consistent, low-risk, non-invasive means of diagnosing CAD. The evolution of multiple cardiac modalities in this field has addressed this dilemma to a large extent, not only in providing information regarding anatomical disease, as is the case with coronary computed tomography angiography (CCTA), but also in contributing critical details about functional assessment, for instance, using stress cardiac magnetic resonance (S-CMR). The field of artificial intelligence (AI) is developing at an astounding pace, especially in healthcare. In healthcare, key milestones have been achieved using AI and machine learning (ML) in various clinical settings, from smartwatches detecting arrhythmias to retinal image analysis and skin cancer prediction. In recent times, we have seen an emerging interest in developing AI-based technology in the field of cardiovascular imaging, as it is felt that ML methods have potential to overcome some limitations of current risk models by applying computer algorithms to large databases with multidimensional variables, thus enabling the inclusion of complex relationships to predict outcomes. In this paper, we review the current literature on the various applications of AI in the assessment of CAD, with a focus on multimodality imaging, followed by a discussion on future perspectives and critical challenges that this field is likely to encounter as it continues to evolve in cardiology.

(1) Introduction: Cardiovascular disease is associated with high mortality, especially in older people. This study aimed to characterize the evolution of combined multimorbidity and polypharmacy patterns in older people with different cardiovascular disease profiles. (2) Material and methods: This longitudinal study drew data from the Information System for Research in Primary Care in people aged 65 to 99 years with profiles of cardiovascular multimorbidity. Combined patterns of multimorbidity and polypharmacy were analysed using fuzzy c-means clustering techniques and hidden Markov models. The prevalence, observed/expected ratio, and exclusivity of chronic diseases and/or groups of these with the corresponding medication were described. (3) Results: The study included 114,516 people, mostly men (59.6%) with a mean age of 78.8 years and a high prevalence of polypharmacy (83.5%). The following patterns were identified: Mental, behavioural, digestive and cerebrovascular; Neuropathy, autoimmune and musculoskeletal; Musculoskeletal, mental, behavioural, genitourinary, digestive and dermatological; Non-specific; Multisystemic; Respiratory, cardiovascular, behavioural and genitourinary; Diabetes and ischemic cardiopathy; and Cardiac. The prevalence of overrepresented health problems and drugs remained stable over the years, although by study end, cohort survivors had more polypharmacy and multimorbidity. Most people followed the same pattern over time; the most frequent transitions were from Non-specific to Mental, behavioural, digestive and cerebrovascular and from Musculoskeletal, mental, behavioural, genitourinary, digestive and dermatological to Non-specific. (4) Conclusions: Eight combined multimorbidity and polypharmacy patterns, differentiated by sex, remained stable over follow-up. Understanding the behaviour of different diseases and drugs can help design individualised interventions in populations with clinical complexity. Full article

Background: Patients with end-stage kidney disease undergoing hemodialysis are particularly vulnerable to severe COVID-19 as a result of older age and multimorbidities. Objectives: Data are still limited and there are no published data on mortality in hemodialyzed patients in Poland, in particular when vaccines became available. We assessed the epidemiologic and clinical data of patients with laboratory-confirmed COVID-19 and assessed the mortality in 2019, 2020, and 2021, as well as the vaccination rate in 2021. Patients and Methods: Retrospectively collected data from 73 Fresenius Nephrocare Poland hemodialysis centers and one public unit were analyzed. Results: In 2021, the vaccination rate was 96%. The unadjusted mortality (number of deaths divided by number of patients) in 2019 was 18.8%, while the unadjusted (after exclusion of COVID-related deaths) mortality in 2020 was 20.8%, and mortality in 2021 was 16.22%. The prevalence of cardiovascular deaths in 2019 and 2020 was almost identical (41.4% vs. 41.2%, respectively), and in 2021, the figures increased slightly to 44.1%. The prevalence of sudden cardiac deaths in 2019 was higher than in 2020 (19.6% vs. 17.3%, respectively) and consequently decreased in 2021 (10.0%), as well as strokes (6.2% vs. 5.4%, and 3.31% in 2021), whereas deaths due to gastrointestinal tract diseases were lower (2.5% vs. 3.2%, and 2.25% in 2021), diabetes complications (0.5% vs. 1.3%, and 0.5% in 2021), sepsis (5.1% vs. 6.3%, and 8.79% in 2021), respiratory failure (1.2 vs. 1.6%, and 2.83% in 2021), and pneumonia (1.4% vs. 2.0%, and 0.82%). There were 1493 hemodialyzed COVID-19 positive patients, and among them, 191 died in 2020 (12.79%). In 2021, there were 1224 COVID-19 positive patients and 260 died (21.24%). The mortality of COVID-19 positive dialyzed patients contributed 13.39% in 2020 and 16.21% in 2021 of all recorded deaths. Conclusions: The mortality among HD patients was higher in 2021 than in 2020 and 2019, despite the very high vaccination rate of up to 96%. The higher non-COVID-19 mortality may be due to the limited possibility of hospitalization and dedicated care during the pandemic. This information is extremely important in order to develop methods to protect this highly vulnerable patient group. Prevention plays a key role; other measures are essential in the mitigation and spread of COVID-19 in HD centers. Full article
