A comprehensive analysis of 200 patients undergoing coronary angiography in Western Maharashtra has revealed that diabetes mellitus and hypertension are the strongest predictors of severe coronary artery disease, with metabolic factors outweighing traditional lifestyle risks in determining disease severity, according to research published in Cureus (2024).

Metabolic syndrome emerges as primary driver
The study, published in Cureus, examined patients presenting for coronary angiography at tertiary care centers across Western Maharashtra. According to the published research, traditional cardiovascular risk factors showed unexpected patterns when analyzed against angiographic severity.
According to Dr. Rajesh Patil, lead researcher at the Department of Cardiology, patients with severe coronary artery disease demonstrated significantly higher rates of diabetes mellitus compared to those with mild to moderate disease. The study challenges conventional assumptions about clinical risk stratification in South Asian populations.
Hypertension patterns show complex relationship
According to the Cureus study, hypertension prevalence varied significantly across disease severity groups, with 68.3% of severe coronary artery disease patients having documented hypertension. The research team noted that the combination of diabetes and hypertension created a multiplicative rather than additive risk profile.
The study found that smoking patterns did not follow expected trends, with moderate smokers showing similar disease severity to heavy smokers. This finding suggests that metabolic factors may override traditional lifestyle risks in this population.
Lifestyle factors show unexpected patterns
The study revealed counterintuitive findings regarding physical activity and dietary habits. According to the research, patients reporting regular exercise showed variable coronary disease severity, suggesting that genetic and metabolic predisposition may be more influential than previously recognized in this demographic.
The Cureus study found that severe coronary artery disease occurred across all age groups, with younger patients (under 50) representing 23% of severe cases. This finding aligns with emerging global trends of premature coronary disease in South Asian populations.
Clinical implications for risk assessment
The Maharashtra study provides crucial insights for cardiovascular risk assessment in South Asian populations. The strong association between metabolic syndrome components and angiographic severity demonstrated in the research suggests that current risk calculators may underestimate disease burden in this population.
Healthcare systems in regions with high diabetes prevalence should prioritize early metabolic screening and aggressive management of glycemic control. The findings support implementation of WHO cardiovascular prevention guidelines with enhanced focus on metabolic parameters.
Diabetes mellitus was present in 73.5% of patients with severe coronary artery disease compared to 32.1% in mild disease cases, representing a 2.3-fold increased risk.

Key takeaways
- Diabetes mellitus is the strongest predictor of severe coronary disease according to the study, present in over 70% of severe cases
- The research found hypertension affects 68.3% of patients with severe coronary artery disease
- The study showed traditional lifestyle factors have weaker associations than metabolic syndrome components
- According to the research, young adults under 50 represent nearly one-quarter of severe coronary disease cases
Frequently asked questions
Why is diabetes so strongly linked to severe coronary disease?
Diabetes accelerates atherosclerosis through multiple mechanisms including endothelial dysfunction, increased inflammation, and altered lipid metabolism. The Maharashtra study confirms this relationship is particularly pronounced in South Asian populations.
Should young adults be screened differently based on these findings?
The study’s finding that 23% of severe cases occur in patients under 50 suggests earlier screening may be warranted, especially for those with diabetes or strong family history of premature coronary disease.
How do these results compare to Western populations?
South Asian populations demonstrate higher rates of diabetes-associated coronary disease at younger ages compared to European populations, likely due to genetic predisposition and metabolic differences.
The Maharashtra findings underscore the need for aggressive primary prevention strategies targeting diabetes and hypertension control to reduce the growing burden of premature coronary disease in this high-risk demographic.
