Cardiovascular diseases (CVDs) remain the leading cause of death in India, with a WHO-reported age-adjusted CVD mortality rate of 349 per 100,000 men. (1) NFHS-5 data show that Indian men aged 40–49 have nearly four times the odds of heart disease compared to adolescents. (2) Moreover, 1.1% of Indian men meet IDF criteria for metabolic syndrome, doubling the risk of CVD and increasing stroke and CVD mortality risk by 1.5-fold. (3,4) These findings underscore the need for individualized primary prevention strategies, such as illustrated in the case scenario.
Why is this case a High CV-Risk?
Hypertension: Contributes to 48% of strokes and 18% of coronary events. (5)
Central Obesity: Visceral fat promotes inflammatory markers (↑FFA, IL-1, IL-6, TNF-α); ↓adiponectin. (6)
High Triglycerides: Contribute to foam cell formation and early atherogenesis. (7)
Elevated TyG Index: Associated with a 33% higher risk of cardiovascular events. (7)
Prediabetes (IFG): Raises the incidence of MACCE to 27.3% vs. 18.4% in normoglycemic individuals. (8)
Ethnicity: South Asian males have significantly higher rates of dyslipidemia and hypertension compared to women, necessitating earlier preventive strategies.(9)
Aspirin in Primary Prevention- Rationale & Guideline Recommendations: Aspirin reduces primary cardiovascular events through irreversible COX-1 inhibition in platelets, decreasing thromboxane A2 production, and reducing platelet aggregation. Additionally, it may lower Lp(a) concentrations by suppressing hepatic apo(a) mRNA expression. (10)
The DCRM (2024) advocates considering low-dose aspirin for primary prevention when patients present with two or more cardiovascular risk factors—such as elevated non-HDL-C, LDL-C, Lp(a), reduced HDL-C, diabetes mellitus, hypertension, chronic kidney disease, smoking, family history of ASCVD, or coronary artery calcium score >100. (11) The USPSTF (2022) endorses aspirin initiation in adults aged 40–59 years with ≥10% 10-year ASCVD risk, whereas ESC (2021) recommends therapy when overall CV risk is high, and ACC/AHA (2019) broadens consideration to individuals aged 40–70 years with elevated ASCVD risk.(10)
All guidelines emphasize that cardiovascular benefits must outweigh bleeding risks, requiring careful assessment and monitoring. Tools like AspirinGuide help clinicians evaluate bleeding risk and support shared decision-making.
Key Takeaway
Men aged 40–50 with metabolic syndrome and multiple CV-metabolic risk factors may represent a prudent consideration as a candidate for primary prevention with aspirin therapy, provided bleeding risk remains acceptably low. The decision must remain individualized, carefully weighing the CV benefits against the bleeding risks through shared decision-making and the use of appropriate risk assessment tools.
