Relationship between modifiable atherosclerotic cardiovascular risk factors and coronary artery bifurcation lesion

Abstract

Background: Modifiable atherosclerotic cardiovascular disease risk factors are hypertension, diabetes mellitus, dyslipidemia, cigarette smoking, and obesity; the term coronary artery bifurcation is used when a coronary artery divides into two hemodynamically important branches or when the main branch has a hemodynamic significant side branch, bifurcation lesion represent 20% or more of coronary artery stenoses undergoing angiography. Objectives: To evaluate the relationship of hypertension, diabetes, dyslipidemia, cigarette smoking, and obesity to coronary bifurcation disease. Materials and Methods: In a cross-sectional study conducted in the Iraqi Center for Heart Diseases from May 2020 to May 2021, a total of 140 adult patients (70 cases with coronary bifurcation lesions and 70 control cases with non-bifurcation lesions) with angiography-documented stenotic coronary artery disease (CAD) were defined. Case demographics and modifiable CAD risk factors were addressed. Results: In the bifurcation group, the non-bifurcation lesion was mostly an associated angiographic finding (82%). The most significantly correlated atherosclerotic risk factor with bifurcation lesion compared to non-bifurcation lesion was diabetes, followed by systemic hypertension. Dyslipidemia was the most common prevalent risk factor, equally distributed in both groups. Smoking and obesity were distributed nearly equally in both groups. Conclusion: There is a significant relationship between diabetes and hypertension with coronary bifurcation lesions compared to non-bifurcation lesions.
