Coexistence of Hypertension, Dyslipidemia, and Central Obesity as Predictors of Early-Onset Ischemic Heart Disease (IHD)
Background: Early-onset ischemic heart disease (IHD) is increasingly prevalent in South Asian populations, driven by the clustering of metabolic risk factors. Hypertension, dyslipidemia, and central obesity are interrelated conditions that may synergistically accelerate coronary atherosclerosis. Objective: To evaluate the coexistence of hypertension, dyslipidemia, and central obesity as predictors of disease severity in patients with early-onset IHD. Methods: A hospital-based cross-sectional study was conducted at SVS Medical College, Mahbubnagar, from January to June 2021. Adults aged ≤55 years (men) and ≤65 years (women) with confirmed IHD were enrolled. Anthropometric measurements, blood pressure, and fasting lipid profiles were assessed. Hypertension, dyslipidemia, and central obesity were defined according to JNC-8, NCEP-ATP III, and WHO/IDF Asian-specific criteria. Statistical analysis included Chi-square tests and binary logistic regression using SPSS version 22. Results: Among 106 participants (mean age 49.6 ± 6.4 years; 67.9% male), hypertension was observed in 58.5%, dyslipidemia in 66.0%, and central obesity in 70.8%. Coexistence of all three risk factors occurred in 45.3% of patients. This triad independently predicted severe IHD (NSTEMI/STEMI) with an adjusted odds ratio of 3.82 (95% CI: 1.54–9.47, p = 0.004). Hypertension and dyslipidemia were also significant individual predictors, whereas central obesity showed a positive but non-significant association. Conclusion: The coexistence of hypertension, dyslipidemia, and central obesity significantly increased the likelihood of severe early-onset IHD. Early screening and simultaneous management of these metabolic risk factors are crucial to reduce premature coronary morbidity and mortality in South Asian adults.
