Abstract

Cardiovascular disease (CVD) remains the leading cause of mortality in South Asia, driven by early-onset coronary artery disease, a high prevalence of cardiometabolic risk factors, and limited access to timely diagnostics and specialist care. Recent years have seen important advances in early detection (high-sensitivity biomarkers, point-of-care testing, imaging, AI-enhanced ECG/echo interpretation) and treatment (expanded use of guideline-directed medical therapies, interventional cardiology, telecardiology and task-sharing models). National and regional initiatives such as WHO’s SEAHEARTS and expanded telemedicine programs are catalyzing uptake of these technologies, though gaps in access, workforce and affordability persist. This article synthesizes recent developments, highlights practical implementation models for resource-constrained settings, and proposes priority actions to scale equitable early diagnosis and effective treatment across South Asia.
