Left main coronary disease is higher in obese patients non-st segment elevated myocardial infarction/unstable angina pectoris

Objective: Obesity' is a major independent risk factor fo r coronary artery' disease. In this study, we aimed to evaluate the angiographical-ly characteristics o f lesions in obese patients admitted with non-ST seg­ment elevated myocardial infarction or unstable angina pectoris. Material and Method: One hundred fifty three patients with acute coronary syndromes (NSTEM I/UAP) were performed coronary angiography. Patients were grouped as body mass index lower than 25 (Group I, n=95) and over 25 (group 2, n=58). Presence o f angio­graphic unstable lesion and coronary lesion distribution were assessed and compared between groups. Statistical analysis was per­form ed by Chi-square test using SP SS 11.0 fo r Windows.Results: Presence o f angiographic unstable lesion was not different between groups [29(%30.5) v.v 22(%37.9), p> 0.05f whereas main vessel disease was higher in obese group despite a statistically insignificance 11(% 1,6) vs 5(% l0,9), p >0.051. Naturally, three vessel disease was increased in both groups admitted with NSTEM I/UAP I21(%45,7) vs 25(%40,3), p>0.05)l. Conclusion: Three vessel disease is higher in either obese or non-obese patients admitted with N STEM I or UAP. Hut it should be remind when an obese patient with NSTEM I/UAP was planned to coronary angiography fo r a possible fu rth er early interventional therapy. Also, presence o f angiographic unstable lesion may lead with such a incidence m ay lead the physician to aggressive antiplatelet therapy.
