I ndia accounts for approximately one-fifth of all global cardiovascular disease (CVD)-related deaths. A 2024 systematic review and meta-analysis places the pooled prevalence of CVD among Indian adults at 11%, with urban populations bearing a higher burden at 12% compared to 6% in rural settings. Coronary artery disease (CAD) prevalence in India's urban population has risen from 1-2% in the 1960s to approximately 10-12% in recent years. CVDs strike Indians a decade earlier than their western counterparts. Hospital admission rates for CAD complications are reportedly 5-10 times higher among those under 40 years of age. In 2016, cardiovascular diseases contributed to 28.1% of all deaths in India, a figure that more than doubled since 1990. Within this context, managing heart blockages remains a pressing clinical challenge. While bypass surgery and angioplasty dominate conventional treatment, a scientifically validated, non-invasive modality has long existed: Enhanced External...

  C oronary stenting is one of the most widely performed cardiac procedures in the world, restoring arterial blood flow rapidly and effectively. Yet a clinically significant proportion of patients who undergo stent placement return — months or years later with recurring symptoms. The question is not marginal: a 2023 meta-analysis in Reviews in Cardiovascular Medicine identified a pooled in-stent restenosis (ISR) rate of approximately 13% for drug-eluting stents, with higher rates in complex anatomical or high-risk metabolic presentations. Understanding why heart blockage after stent placement recurs is essential for any patient managing long-term coronary artery disease. What a Stent Treats — and What It Does Not A stent addresses a localised anatomical obstruction: it mechanically expands a narrowed coronary lumen and, in the case of drug-eluting devices, locally suppresses the cellular proliferation that drives early re-narrowing. This is its precise and limited mandate. ...

Cardiovascular disease remains the leading cause of mortality worldwide, accounting for an estimated 17.9 million deaths each year, according to the World Health Organization. These deaths represent approximately 32% of all global deaths, with over four out of five cardiovascular disease (CVD) fatalities resulting from heart attacks and strokes. Yet for all the clinical attention directed at the heart as a standalone organ, a foundational concept in cardiovascular physiology is routinely overlooked — the human body does not rely on a single pump to sustain circulation; It relies on three . (check the video) This is not a metaphor. It is grounded in well-established haemodynamic science. Adequate blood circulation, particularly venous return from the lower extremities back to the cardiac chambers, depends on coordinated contributions from the myocardium, the skeletal muscle pump of the lower limb, and the endothelial and vascular tone of the peripheral blood vessel network. When any on...
