Sex disparity of DAPT noncompliance in patients with left main stem PCI with DES.

This retrospective study aims to explore the sex disparity in dual antiplatelet therapy (DAPT) noncompliance among left main stem percutaneous coronary intervention (PCI) patients with drug-eluting stent (DES) and identify predictors associated with non-adherence. Data were collected from the medical records of 1585 patients, including 1104 males and 481 females, who underwent left main stem PCI with DES. Baseline characteristics, angiographic features, and DAPT compliance rates at 1 month and 12 months were analyzed. Univariate logistic regression was used to identify predictors of DAPT noncompliance. The overall DAPT noncompliance rate at 1 month was 8.5%, increasing to 15.5% at 12 months. Females exhibited slightly higher noncompliance rates than males at both 1 month (15.6% vs 14.5%) and 12 months (28.1% vs 19.0%), although the difference was not statistically significant. Smoking status showed a modest impact on non-adherence, with current smokers exhibiting a lower noncompliance rate (14.9% at 1 month). Prior coronary artery disease history was associated with increased noncompliance at 12 months (18.9%). Angiographic characteristics, including lesion location and Syntax score, had no consistent association with DAPT noncompliance. This study highlights sex disparity in DAPT noncompliance among patients undergoing left main stem PCI with DES. Comorbidities, socioeconomic status, smoking status, and prior coronary artery disease history were identified as predictors of non-adherence.

Altitude-Related Venous Thrombosis With Heart Disease: An Updated Review.

Altitude-related venous thrombosis (ARVT) is a condition of growing concern among individuals engaged in high-altitude travel and activities. This updated review explores the epidemiology, pathophysiological mechanisms, clinical presentations, and management of ARVT based on a thematic analysis and synthesis of the existing literature. ARVT's multifactorial etiology involves the interplay of hypobaric hypoxia and endothelial dysfunction, creating a procoagulant state and increasing the risk of thrombosis. Common clinical manifestations include pain, swelling, and redness in the extremities, necessitating accurate and timely diagnosis, particularly in remote settings. Thromboprophylaxis during high-altitude travel and activities plays a crucial role in reducing the risk of ARVT, while anticoagulation remains the mainstay of management. Further research is needed to optimize preventive and treatment strategies, enhancing patient outcomes and safety in high-altitude environments.
