Objective: Evaluate the efficacy and safety following intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy in patients with diabetic macular oedema (DME). Methods: To evaluate retinal microvascular remodelling and photoreceptor metrics using adaptive optics (AO) alongside systemic vascular status assessed by brachial/aortic hemodynamic and carotid ultrasound. We conducted a single-centre longitudinal study including twenty-one patients with DME. The following four diagnostic visits were performed: baseline (V1, no anti-VEGF treatment), 2–3 months (V2), 6–8 months (V3), and 12–14 months (V4). Adaptive optics (rtx1) measured foveal cone number (N) and regularity (Reg) within a standardised 80 × 80 µm window, and superior temporal retinal arteriole morphology after the first bifurcation (vessel diameter [VD], lumen diameter [LD], wall thickness [WT], wall-to-lumen ratio [WLR], and wall cross-sectional area [WCSA]). SphygmoCor provided peripheral (brachial) and central (aortic) pressures, augmentation pressure (AP), augmentation index (AIx), and carotid–femoral pulse wave velocity (PWV and PWVHR heart rate adjusted). Carotid ultrasound assessed intima–media thickness (IMT), carotid lumen diameter (CLD), and IMT/CLD ratio (IMTLR) 2 mm proximal to the bifurcation in diastole. Visual acuity (Visus), intraocular pressure (IOP), and central retinal thickness (CRT) were obtained at each visit. Results: In the treated eye (TE), WLR showed a significant overall change (Friedman p = 0.007), with a modest V4 vs. V1 increase (Wilcoxon p = 0.045); LD also varied across visits (Friedman p = 0.034). Cone metrics improved as follows: Reg increased over time (Friedman p = 0.019), with a significant rise at V4 vs. V1 (p = 0.018), and cone number increased at V3 vs. V1 (p = 0.012). Functional/structural outcomes improved as follows: visual acuity increased at V3 (p = 0.009) and V4 (p = 0.028), while CRT decreased at V3 (p = 0.002) and V4 (p = 0.030); IOP remained stable compared to V1. Systemic hemodynamics was largely unchanged; small fluctuations in DBP and cDBP across V1–V4 were observed (Friedman p = 0.034 and p = 0.022, respectively), whereas AIx, AP, PWV, and PWVHR showed no significant trends. Carotid IMT, CLD, and IMTLR did not change significantly across visits, supporting systemic vascular safety. Conclusions: Intravitreal anti-VEGF therapy in DME was associated with improvements in photoreceptor organisation and macular structure/function, with AO-derived arteriolar remodelling detectable over time, and no adverse changes in large-artery structure. These findings support ocular efficacy and systemic vascular safety; confirmation in larger cohorts is warranted. Full article

Background/Objectives: Long COVID (LC) has been linked to fatigue, exercise intolerance, and autonomic dysfunction, but sex-stratified data on cardiovascular responses to maximal exercise—an essential component of personalized medicine—are scarce. This study aimed to examine hemodynamic, autonomic, and functional responses during and up to 24 h after a cardiopulmonary exercise test (CPET) in young adults with and without Long COVID (LC). Methods: In this cross-sectional study, we assessed 38 physically active adults, who were allocated into four subgroups stratified by clinical condition (LC or control) and biological sex: control–female (CON-F; n = 10), LC–female (LC-F; n = 10), control–male (CON-M; n = 10), and LC–male (LC-M; n = 8). Outcomes included systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR), cardiac output (CO), total (TPR) and peripheral vascular resistance (PVR), pulse wave velocity (PWV), augmentation index (AIx@75), and heart rate variability (HF, LF, LF/HF), assessed at rest, peak effort, recovery (1, 3, 5, 10, 30, and 60 min), and through 24 h ambulatory blood pressure monitoring (ABPM) after CPET. Results: SBP increase appropriately during exercise, with higher peaks in males (p < 0.01), and returned to baseline within 5 min across all groups. HR recovery was preserved; however, LC-F showed lower values than CON-F at 3, 5, and 10 min (126 vs. 144 bpm, p = 0.020; 119 vs. 136 bpm, p = 0.020; 94 vs. 109 bpm, p = 0.011), though all groups normalized by 60 min. PWV, AIx@75, TPR and PVR exhibited expected sex-related patterns without LC-related impairments. HRV indices showed transient post-exercise shifts (HF↓, LF↑, LF/HF↑). Ambulatory monitoring confirmed preserved circadian modulation, with normal systolic dipping (11–13%) and no abnormal nocturnal patterns. Conclusions: Young physically active adults with LC showed preserved hemodynamic, autonomic, and vascular responses during and after maximal exercise. These findings contribute to personalized medicine by showing that individualized, sex-stratified cardiovascular assessments reveal no clinically relevant impairments in this population, supporting tailored clinical decision making and exercise prescription.

Cardiovascular disease (CVD) remains the leading cause of death worldwide, accounting for nearly one-third of global mortality. Arterial stiffening, particularly in the central elastic arteries, impairs the Windkessel (cushioning and pumping) function and contributes to cardiovascular risk beyond traditional factors. Carotid–femoral pulse wave velocity (cfPWV) is established as the gold standard for assessing aortic stiffness and predicting cardiovascular and all-cause mortality; however, its technical complexity and requirement for trained personnel limit its use in routine clinical and community settings. These challenges have driven the development of simplified techniques for population screening, such as brachial–ankle PWV (baPWV). More recently, single-cuff oscillometric devices have emerged as practical alternatives. These methods are simple enough to be implemented in daily healthcare at home, thereby greatly enhancing accessibility, although their accuracy depends on model assumptions and calibration. In this perspective article, we highlight the pathophysiological significance of preserving the central arterial Windkessel function and emphasize the need for its practical assessment. Recent innovations mark a paradigm shift from complex laboratory-based measurements toward simplified, data-driven, and socially feasible screening tools for the early detection and prevention of CVD.

Background: Diabetes is associated with sub-optimal vascular function. Current evidence suggested purified anthocyanins (ACNs) could improve cardio-metabolic health, but the dose–response effects on arterial stiffness have not been verified. Objectives: To assess the dose-responsiveness of purified ACNs on vascular stiffness and cardiovascular risk among Chinese middle-aged and elderly patients with either prediabetes or early diabetes. Methods: This was a secondary analysis based on a 12-week double-blind, randomized and placebo-controlled trial. Eligible participants were randomly assigned to placebo, 160, 320 and 640 mg/d ACNs groups (n = 46/group). Information on dietary intakes and lifestyle habits and blood samples were collected at baseline and at week 12. Arterial stiffness and vascular function were measured by brachial-ankle pulse wave velocity (baPWV), ankle-brachial index (ABI) and four-limb blood pressures. Composite cardiovascular indices were estimated based on lipids and anthropometric data. Results: Total 184 eligible participants were recruited and 19 withdrew during the intervention. Baseline characteristics were generally comparable among groups. No significant effects or dose–response relationships were observed by ACNs supplementation on arterial stiffness and cardiovascular risk factors. Conclusions: The 12-week randomized controlled trial among Chinese middle-aged and elderly adults with dysglycemia showed multiple dosages of anthocyanins had no significant impacts on arterial stiffness and cardiovascular risk.

Background: Vitamin D (VD) insufficiency is present in chronic pancreatitis (CP), leading to increased cardiovascular risk, bone complications, impaired quality of life, and increased mortality. This study aimed to determine the prevalence of VD deficiency in patients with CP and to assess its relationship to CP progression and associated cardiovascular complications. Methods: Seventy patients were enrolled and evaluated for pancreatic exocrine insufficiency by fecal elastase-1, CP severity by M-ANNHEIM classification, cardiovascular risk by 10-year risk mortality scores (SCORE and FRS), and for arterial stiffness using pulse wave velocity (PWV) at a. carotis and a. femoralis. Determination of 25-hydroxyvitamin D was performed by an LC-MS/MS method. Resting energy expenditure was calculated using the Harris–Benedict formula. Results: Mean VD levels were 37.86 ± 24.36 nmol/L (range 3.854–99.874 nmol/L); only five patients were in sufficiency status. VD levels correlated significantly with body mass index (BMI) and resting energy expenditure. In patients with severe structural changes, we observed lower VD levels regardless of etiology (p < 0.01). VD levels were lower in patients with pancreatic exocrine insufficiency (PEI), p < 0.05. Patients with mild CP by M-ANNHEIM had lower levels of VD compared to moderate and advanced CP, p < 0.05. At a cut-off of VD 11.95 nmol/L, we verified pancreatic lithiasis with 89.4% sensitivity, 83.3% specificity, and AUC of 0.826 ± 0.113 (95% CI, 0.61–1). VD status worsened with the increase in the 10-year risk mortality by both SCORE and FRS and PWV, p < 0.05. Conclusions: Most of our patients with CP were VD insufficient. Monitoring of nutritional status in patients with CP is mandatory to prevent the development of malnutrition complications and the associated morbidity and mortality. Full article

Background/Objectives: Heart failure with preserved ejection fraction (HFpEF) accounts for nearly half of all heart failure cases and remains challenging to diagnose and manage due to its complex, multifactorial nature. Increasing evidence highlights the significance of arterial stiffness, assessed by pulse wave velocity (PWV), and autonomic dysfunction, reflected by impaired heart rate recovery (HRR) after exercise, as relevant markers in HFpEF. This review aims to synthesize current knowledge on the diagnostic and prognostic value of PWV and HRR in HFpEF. Methods: A narrative literature review was conducted using PubMed to identify studies published between 2009 and 2025 that investigated PWV and HRR in patients with HFpEF or populations at risk. Included studies ranged from invasive hemodynamic measurements and cardiopulmonary exercise tests to large cohort analyses such as IDENTIFY-HF and MESA. Key findings were summarized in comparative tables. Results: Patients with HFpEF consistently show higher PWV than age-matched controls, supporting the concept of HFpEF as a systemic vascular disorder. Elevated PWV has been linked to increased risk of HFpEF onset and poorer outcomes. Likewise, blunted HRR indicates autonomic imbalance and is strongly associated with higher morbidity and mortality. Interventions including structured exercise training and optimized risk factor management may help improve PWV and HRR. Conclusions: PWV and HRR offer valuable, complementary insights for risk stratification and individualized care in HFpEF. Further research should focus on integrating these parameters into diagnostic algorithms and evaluating targeted therapies that address vascular stiffness and autonomic dysfunction. Full article

Background: Although brachial–ankle pulse wave velocity (baPWV) has been used to predict cardiovascular events, studies comparing it with brachial pulse pressure (brPP) for predictive value have been lacking. We investigated how brPP and baPWV differ in their ability to predict future cardiovascular events. Methods: We retrospectively reviewed the clinical data of 11,703 consecutive patients where brPP and baPWV measurements had been made. The primary endpoint was differences in the incidence of major adverse cardiovascular and cerebrovascular events (MACCE). Results: Participants had a median age of 61 years, and men accounted for 57.7% of the cohort. During a median follow-up duration of 3.64 years, 347 (3.0%) MACCE occurred. Using established reference values of baPWV > 1800 cm/s and brPP > 60 mmHg, we, respectively, stratified patients by these values. Kaplan–Meier survival curve analysis revealed that both high baPWV and brPP groups displayed elevated MACCE incidence, all-cause mortality, and cardiovascular mortality. After controlling for potential confounders, multivariate Cox regression analysis showed that individuals with elevated baPWV had higher rates of MACCE, overall mortality, and cardiovascular death, whereas brPP was not significantly associated with these outcomes. Subgroup analysis showed a consistent difference in MACCE incidence across all subgroups when stratified by baPWV; however, the significance disappeared in several subgroups when stratified by brPP. Conclusions: baPWV exhibited a stronger association with MACCE incidence than brPP. Thus, baPWV may be a more effective factor than brPP for cardiovascular risk stratification. Full article

Background/Objectives: Phenylacetylglutamine (PAG), a gut microbiota-derived metabolite, may contribute to the development of cardiometabolic diseases. The diagnostic value of PAG for vascular dysfunction in hemodialysis (HD) remains unclear. This study assessed how serum PAG levels relate to carotid–femoral pulse wave velocity (cfPWV), which is a validated index of aortic stiffness, in patients on maintenance HD. Methods: A total of 138 patients on maintenance HD were enrolled. Participants with cfPWV values greater than 10 m/s were categorized as having aortic stiffness. Serum PAG levels were measured using high-performance liquid chromatography–mass spectrometry. Results: Aortic stiffness was present in 33.3% of patients. Those with aortic stiffness were older (p = 0.016), had a higher prevalence of diabetes mellitus (p = 0.030) and hypertension (p < 0.001), and had higher systolic (p < 0.001) and diastolic (p < 0.001) blood pressures, glucose (p = 0.005), and serum PAG (p < 0.001) levels. Multivariable analysis identified serum PAG (odds ratio [OR] = 1.903; 95% confidence interval [CI] = 1.171–3.094, p = 0.009) and age (OR = 1.042, 95% CI = 1.001–1.084, p = 0.044) as independent determinants of aortic stiffness. Linear regression revealed that PAG (p < 0.001), systolic blood pressure (p < 0.001), age (p = 0.013), and glucose level (p = 0.024) were positively associated with cfPWV. Conclusions: Among individuals undergoing maintenance HD, higher serum PAG levels independently predicted greater aortic stiffness. PAG may be a potential diagnostic biomarker for vascular stiffness and a tool for cardiovascular risk stratification in this population. Full article

Background: Obesity is a substantial global health issue associated with increased risk of cardiovascular disease (CVD) and metabolic dysfunction-associated steatotic liver disease (MASLD). Despite the known link between obesity, CVD and MASLD, it remains unknown which factors contribute to higher cardiovascular (CV) risk in patients with obesity-induced liver fibrosis. Liver fibrosis, assessed by the Fibrosis-4 (FIB-4) index, may help to identify patients with obesity at increased CV risk. Methods: Patients with severe obesity (Body Mass Index (BMI) ≥ 40 kg/m2) scheduled for bariatric surgery were subdivided into FIB-4 categories. Systemic leukocyte activation markers were measured by flow cytometry. Additionally, markers of vascular damage, namely the carotid intima media thickness (cIMT) and pulse wave velocity (PWV), were included. Results: The cohort predominantly consisted of women (74%) with an average age of 41 years and mean BMI of 42.7 kg/m2. Patients with an elevated FIB-4 (≥1.3) had higher systolic (146 ± 16 vs. 139 ± 15, p = 0.002) and diastolic blood pressure (91 ± 13 vs. 83 ± 12, p = 0.002), increased cIMT (0.66 ± 0.11 vs. 0.55 ± 0.10, p < 0.001), and higher PWV (8.2 ± 0.9 vs. 6.8 ± 1.1, p < 0.001) compared to those with a low FIB-4 (<1.3). Additionally, patients with a high FIB-4 tended to show increased expression of CD66b on granulocytes. Conclusions: Patients with severe obesity who were at risk of liver fibrosis showed greater signs of vascular damage, insulin resistance, and systemic inflammation. This suggests that liver fibrosis can be a useful marker for identifying patients with obesity at high CV risk. Full article

Background: Acute and chronic hyperglycemia in patients with type 2 diabetes mellitus (T2DM) causes endothelial dysfunction and arterial stiffness, contributing to early mortality from cardiovascular disease (CVD). Although L-citrulline (CIT) supplementation improves endothelial function in older women and decreases fasting glucose in those with T2DM, whether it improves vascular function and blood glucose during acute hyperglycemic states in T2DM is unknown. Methods: We randomized 16 patients with T2DM (age 62 ± 6 years) to consume either CIT (6 g/day) or placebo for 4 weeks. Brachial artery flow-mediated dilation (FMD), brachial and aortic blood pressure, aortic and leg arterial stiffness (pulse wave velocity, PWV), and blood glucose concentration were assessed in the fasted state and 60 min following glucose ingestion (during acute hyperglycemia). Results: Four weeks of L-citrulline supplementation improved FMD, femoral-ankle PWV, aortic systolic blood pressure, and blood glucose concentration in the fasted state compared to placebo (all p < 0.05). During acute hyperglycemia, CIT supplementation increased FMD and reduced femoral-ankle PWV, aortic systolic BP, and glucose levels compared to placebo (all p < 0.05). Conclusions: CIT supplementation is beneficial to improve vascular function and glucose levels during chronic and acute hyperglycemia in middle-aged and older adults with T2DM. Full article

Introduction: Chronic kidney disease (CKD) is associated with a high risk of cardiovascular complications and mortality. This study aimed to assess the relationship between the diurnal blood pressure (BP) profile, progression of CKD, and hypertension-mediated organ damage (HMOD) in patients with CKD stages 1–3 during a 6-month observation period. Methods: Eighty-seven patients with CKD stages 1–3 underwent 24 h ambulatory blood pressure monitoring (ABPM), echocardiography, carotid intima-media thickness (IMT) assessment, and aortic pulse wave velocity (PWV) measurement at baseline and after 6 months. Serum creatinine and the estimated glomerular filtration rate (eGFR) were evaluated using the CKD-EPI formula. Results: Based on ABPM, patients were classified as dippers/extreme dippers (D/ED, 35.6%), non-dippers (ND, 47.2%), and reverse dippers (RD, 17.2%). At follow-up, the RD group showed a significant decline in the eGFR and a lower left ventricular ejection fraction compared to D/ED. IMT values were consistently higher in RD than in D/ED at baseline and follow-up. No significant differences in PWV were observed. Conclusions: An abnormal diurnal BP profile is common in patients with CKD stages 1–3. The “reverse dipper” profile is associated with faster CKD progression, more advanced vascular remodeling, and reduced left ventricular function. The results of our study support the role of ABPM as a useful tool in assessing risk in the early stages of CKD, providing additional prognostic information beyond office blood pressure measurements. Limitations: The relatively small sample size, short follow-up period, lack of detailed data on treatment modifications, and absence of orthostatic BP assessment may limit the interpretation and generalizability of the results.

Background/Objectives: Arterial stiffness increases with progressive worsening of renal function and predicts cardiovascular mortality in patients with chronic kidney disease. The effects of vitamin K-dependent proteins in vascular health and the implications of vitamin K epoxide reductase gene (VKORC1) polymorphisms in calcification and warfarin sensitivity are well known, but their roles in arterial stiffness are not known. We investigated the influence of common polymorphisms in this gene (−1639G>A, +1173C>T, +1542G>C, +2255C>T, and +3730G>A) on stiffness and calcification markers in 302 CKD patients. Methods: Blood pressure, aortic pulse wave velocity (aPWV), coronary artery calcification (CAC), and aortic calcification (AC) were assessed together with the total uncarboxylated matrix Gla protein (t-uncMGP). Results: Genotyping subjects for +1542G>C and +3730G>A showed higher genotype-specific aPWV and lower t-uncMGP (p < 0.05). The combined recessive allele model showed a significant stepwise reduction in aPWV (p < 0.005); subjects homozygous for both risk alleles had the highest aPWV compared to those carrying one or none. In a multiple regression model adjusting for age, gender, mean pressure, BMI, and racial group, each +1542G allele and +3730A allele were independently associated with a 0.8 m/s (95% CI 0.09 to 1.57) and 1.0 m/s (95% CI 0.14 to 1.98) elevation of aPWV, respectively. Although serum t-uncMGP levels correlated inversely with CAC score (p < 0.001), VKORC1 genotypes did not. Conclusions: We demonstrated for the first time that VKORC1 polymorphisms (+1542G>C and +3730G>A) influence arterial stiffness and serum t-uncMGP levels in CKD patients. These findings suggest that vitamin K-dependent processes may be important in arterial stiffness, possibly by modulating calcification of the vessel wall. Full article

Background: Metabolically Associated Fatty Liver Disease (MAFLD) is a prevalent liver disorder closely tied to metabolic dysfunction, insulin resistance, and chronic low-grade inflammation. Vascular Endothelial Growth Factor (VEGF) may have a dual interesting role in MAFLD pathophysiology—supporting vascular repair in early stages, but potentially contributing to fibrosis in later stages. In this study, berberine (BBR), a plant-derived isoquinoline alkaloid, exhibits multiple beneficial properties, including anti-inflammatory, antioxidant, and endothelial-protective effects, on the study group, perhaps by influencing VEGF concentration. Objective: This study aimed to investigate the effectiveness of BBR in addressing vascular function parameters linked to MAFLD, particularly its impact on serum VEGF levels and arterial stiffness. Methods: This randomized, double-blind, placebo-controlled clinical trial enrolled seventy individuals with MAFLD who were overweight or obese. Participants were randomly assigned in a 1:1 ratio to receive either BBR (1500 mg/day) or a placebo orally for 12 weeks. The following parameters were assessed pre- and post-intervention: VEGF, brachial SBP (Systolic Blood Pressure)/DBP (Diastolic Blood Pressure), MAP (Mean Arterial Pressure), AIx (Augmentation Index), AP (Aortic Pressure), number of waveforms, Pulse Pressure (PP), PWV (Pulse Wave Velocity), and PWA-SP/PWA-DP (Pulse Wave Analysis Systolic/Diastolic Pressure). The results for the metabolic parameters—FLI (Fatty Liver Index)—and anthropometric parameters—BMI (Body Mass Index), fat mass corp—and laboratory parameters, among them, hsCRP (high-sensitivity C-reactive protein), were published by us earlier. Results: In the BBR-treated cohort, VEGF concentrations demonstrated a statistically significant increase following the intervention, rising from a baseline mean of 456.23 ± 307.61 pg/mL to 561.22 ± 389.77 pg/mL (p < 0.0001). In the BBR group, a significant reduction in PWA-SP was observed after 12 weeks of supplementation (134.85 ± 16.26 vs. 124.46 ± 13.47 mmHg, p < 0.0001). No statistically significant differences were observed in the parameters determining arterial stiffness in the BBR and placebo groups. In the BBR group, delta VEGF correlated negatively with delta FLI; no such associations were observed in the placebo group. Changes in PWV were consistent and significantly correlated with changes in brachial SBP/DBP, PWA-SP, PWA-DP, and MAP. No serious adverse events were reported, and BBR was well tolerated. Conclusions: BBR appears to be a safe and promising adjunct in MAFLD therapy, potentially exerting reparative effects through VEGF modulation and vascular support. Further research is warranted to confirm its long-term impact and elucidate underlying protective mechanisms. Full article

Hypertension, a leading factor for cardiovascular diseases (CVD), is a particularly heavy burden in women during middle age, when cardioprotective hormones begin to decline. The abnormal handling of calcium (Ca2+) in vascular smooth muscle cells (VSMCs) leads to increased vasoconstriction, remodeling, and altered arterial compliance during hypertension. The Spontaneously Hypertensive Rats (SHR) is a model of essential hypertension, and middle-aged females with hypertension represent a stage of disease where vascular dysfunction is prominent but understudied. Losartan, a widely prescribed angiotensin II (AngII) receptor (AT1R) blocker, exerts antihypertensive effects by affecting Ang II/Ca2+ signaling. However, whether it corrects the Ca2+ mishandling in the aorta of middle-aged female SHR has not been established. In this study, the thoracic aorta from 36-week-old female SHRs treated with losartan was assessed for Ca2+ mishandling using myography and biochemical assays. Meanwhile, biomechanical properties and stiffness were evaluated using Pulse Wave Velocity (PWV), Atomic Force Microscopy (AFM), and assessments of collagen and elastin contents. Compared with normotensive controls, SHR demonstrated disrupted Ca2+ handling, increased stiffness, and Extracellular Matrix (ECM) remodeling in middle-aged females. Treatment with losartan abrogated Ca2+ mishandling influx and efflux in the VSMC, decreased stiffness, and restored the aortic structural changes. These findings demonstrate that losartan abolishes Ca2+ mishandling and highlight a mechanistic role of AT1R blockade in restoring vascular function in the aorta of middle-aged females during hypertension.

Background: Arterial stiffness assessed by measuring pulse wave velocity (PWV) is a well-established predictor of cardiovascular mortality. To our knowledge, no studies on arterial stiffness in kidney transplant recipients (KTRs) from Tunisia have been conducted. The present study aimed to assess arterial stiffness in Tunisian KTRs and to identify the key predictors associated with its increase. Methods: We conducted a cross-sectional, single-center study enrolling Tunisian KTRs aged 18 years or older with a minimum post-transplant follow-up of six months. Arterial stiffness was measured as pulse carotid–femoral PWV (CF-PWV) by a Complior device. A CF-PWV ≥ 10 m/s was defined as elevated. Results: Fifty-four KTRs were included (mean age: 42.55 ± 10.61 years). Among them, 19 (35.2%) had a CF-PWV ≥ 10 m/s. The univariate analysis showed a significant association between elevated CF-PWV and the following parameters: age, hypertension prior to transplantation, dyslipidemia, donor age, parameters obtained through office blood pressure measurement (systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP)), central SBP recorded by the Complior device, nocturnal SBP obtained through 24 h ambulatory blood pressure monitoring (ABPM), and fasting blood glucose. A multivariable analysis with CF-PWV ≥ 10 m/s as a dependent variable retained the following independent factors: dyslipidemia (p = 0.015; OR = 60.32), donor age (p = 0.014; OR = 1.16), SBP obtained through office blood pressure measurement (p = 0.015; OR = 1.25), and fasting blood glucose (p = 0.034; OR = 22.35). Conclusions: Given the major impact of cardiovascular disease on post-transplant outcomes, understanding the determinants of arterial stiffness is crucial for improving patient care. Routine PWV assessment may not be feasible in all centers due to cost or limited equipment availability. Therefore, identifying the clinical and biological markers associated with arterial stiffness offers a low-cost and widely accessible alternative for evaluating cardiovascular risk. These findings may support the development of a simple risk score to help nephrologists detect and manage high-risk KTRs more effectively. Full article
