Background: The intermittency of conventional hemodialysis (HD) leads to an increase in cardiovascular events.

Objective: We aimed to evaluate the effect of in-center frequent HD (FHD, 4-6 times a week) as a rescue option for cardiovascular events.

Method: Patients who failed to achieve fluid volume control with conventional HD (thrice a week) were administered FHD. A total of 52 patients were divided into 2 groups by left ventricular ejection fraction (LVEF): low ejection fraction (LEF [n = 26], LVEF < 55%) and normal ejection fraction (NEF [n = 26], LVEF ≥55%). Mortality and hospitalization rates were evaluated.

Results: All-cause mortality tended to be higher in the LEF than in the NEF group (p = 0.09). The 1-year hospitalization rate for acute cardiovascular events decreased in both LEF (1.24-0.89; p = 0.049) and NEF (0.36-0.16; p = 0.01) groups. In Cox regression models, LVEF < 55% (hazard ratio 3.81; 95% CI 1.15-12.66; p = 0.03) was identified as the risk factor for hospitalization for acute cardiovascular events.

Conclusion: In-center FHD may decrease acute cardiovascular events.

Introduction/objective: Emotional, mental, or psychological distress, defined as increased symptoms of depression, anxiety, and/or stress, is common in patients with chronic diseases, such as cardiovascular (CV) disease (CVD).

Methods: Literature was reviewed regarding data from studies and meta-analyses examining the impact of emotional stress on the occurrence and outcome of several CVDs (coronary disease, heart failure, hypertension, arrhythmias, stroke). These influences' pathophysiology and clinical spectrum are detailed, tabulated, and pictorially illustrated.

Aims: This study was to explore the relationship between plasma exosomes and Acute myocardial infarction (AMI).

Background: Acute myocardial infarction (AMI) is one of the most common cardiovascular complications. Recent studies have shown that exosomes play a crucial role in the development and progression of cardiovascular diseases.

Purpose: Heart failure (HF) management is well-defined for reduced ejection fraction (HFrEF) but less so for mildly reduced (HFmrEF) or preserved ejection fraction (HFpEF). This meta-analysis evaluates the impact of Finerenone, a nonsteroidal mineralocorticoid receptor antagonist, on cardiovascular and renal outcomes in these patient populations.

Methods: A systematic search in PubMed and Embase identified randomized controlled trials (RCTs) on Finerenone's cardiovascular and renal effects.

Background: Severe left ventricular (LV) systolic dysfunction (ejection fraction [EF] < 30%) is a known cardiovascular risk factor and a major cause of cardioembolism. However, less severe forms of LV disease (LVD), such as mild-to-moderate LV dysfunction and LV wall motion abnormalities (LVWMAs), are considered potential minor cardiac sources in Embolic Stroke of Undetermined Source (ESUS), but their role is underexplored. This study aims to evaluate the prevalence of LVD in ESUS and its association with adverse vascular events and mortality.

Introduction: We explored the efficacy and safety of dual antiplatelet therapy (DAPT) for individuals diagnosed with stroke or transient ischaemic attack (TIA), incorporating the latest insights from randomised controlled trials (RCTs). The emerging evidence surrounding DAPT in stroke and TIA plays a pivotal role in guiding clinical decisions.

Methods: Our study included five RCTs (INSPIRES, THALES, POINT, CHANCE, FASTER) on DAPT (aspirin + P2Y12 inhibitor) initiated within 72 hours of acute stroke or TIA, which evaluated DAPT efficacy and safety over 21-90 days, focusing on new strokes and major bleeding.
