Key result
BMI shows no link to CAD severity in patients 45 or younger presenting with ACS.
Why the study?
Data on the relationship between high BMI and the incidence and severity of CAD are variable, particularly in young patients.
Does body mass index affect the severity of coronary artery disease in young patients (≤45 years) with acute coronary syndrome?
Observational (n=150)
Does body mass index affect the severity of coronary artery disease in young patients (≤45 years) with acute coronary syndrome?
In young patients presenting with acute coronary syndrome, BMI category was not significantly associated with the angiographic severity of coronary artery disease.
Does not support BMI-based prediction of CAD severity in young ACS; leaves open obesity's role and requires larger prospective studies.

If the affected person is young, the consequences are more tragic. There are variable information on the relation of incidence and severity of coronary artery disease in high BMI populations. We have examined the association between BMI and severity of coronary artery disease in young onset Acute Coronary Syndrome (ACS). Methods In this prospective observational study a total number of 150 patients, aged ≤45 years presented with acute coronary syndrome were enrolled to analyze association between Body Mass Index (BMI) and severity of coronary artery disease. Results The mean BMI in male was 24.6±3.6 and the mean BMI in female was 25.4±3.3. Among the 150 patients, 2(1.3%) was underweight, 78(52%) was normal, 60(40%) was overweight & 10(6.7%) was obese. All underweighted patients were diagnosed as STEMI. Among the normal BMI patients, 18(23.1%) had UA, 12(15.4%) had NSTEMI & 48 (61.5%) had STEMI. Among the overweight patients, 23(38.3%) had UA, 9(15%) had NSTEMI & 28(46.7%) had STEMI. And among the obese patients, 4(40%) had UA, 1 (10%) had NSTEMI & 5(50%) had STEMI. Considering involving coronary artery, left main coronary artery involvement was 0(0%), 6 (7.7%), 5 (8.3%) & 0(0%) in underweight, normal, overweight & obese patients respectively. Left anterior descending coronary artery involvement was 2(100%), 54 (69%), 45 (75%) & 7 (70%) in underweight, normal, overweight & obese patients respectively. Left circumflex coronary artery involvement was 1(50%), 33 (42%), 25 (41.7%) & 1 (9%) in underweight, normal, overweight & obese patients respectively. And right coronary artery involvement was 1(50%), 35 (44.9%), 31 (51.7%) & 5 (50%) in underweight, normal, overweight & obese patients respectively. In underweight patients 1(50%) had SVD and 1 (50%) had TVD. In normal BMI patients 40 (51.3%) had SVD, 11(14.1%) had DVD and 19 (24.4%) had TVD. In overweight patients 27 (45%) had SVD, 15 (25%) had DVD and 13 (21.7%) had TVD. And in obese patients 5 (50%) had SVD, 3(30%) had DVD and 0 (0%) had TVD. In all BMI group SVD was more common. Conclusion There is no statistically significant differences in severity of coronary artery in respect to body mass index (BMI), in patients presented with acute coronary syndrome.

Moniruzzaman et al. (2023) conducted an observational in Acute Coronary Syndrome (n=150). Body Mass Index (BMI) was evaluated on Severity of coronary artery disease. Body mass index (BMI) showed no statistically significant association with the severity of coronary artery disease in patients aged ≤45 years presenting with acute coronary syndrome.
