Diameter of normal coronary arteries in adult pakistanis.
Pak Heart J Jan ;51(2):145-53.

Objective: To determine the diameters of normal coronary arteries in a group of adult Pakistanis and to compare the results with the data mentioned in literature. Methodology: Cross-sectional study conducted at Department of Cardiology, Shaikh Zayed Hospital, Lahore from December 2015 to December 2016. Study population comprised of patients who had normal coronary angiograms. The arterial segments were divided according to 29-segment model. The selected segments were studied by quantitative coronary angiography (QCA) method. Results: Mean age of participants was 55.46+-10.8 years, mean BSA,1.84+-0.187 and mean BMI was 28.18+-2.4 Kg/m . Indexed coronary diameters of males and females were not significantly different.+-Diameters of(PLAD) and Proximal Left Circumflex (PLCx) were larger and diameter of left main stem was smaller in the present study compared to local studies. Diameter of Mid right coronary (MRCA) was larger and diameters of left main, proximal right coronary (PRCA), mid (MLAD), distal (DLAD) and distal left circumflex (DLCx) were smaller in the present study compared to Caucasians. Diameters of PLAD, MLAD, DLAD and PLCx were larger and diameters of left main stem and MRCA were smaller in the present study than Caucasians of another study. Conclusion: Coronary artery diameters may have some peculiarities as some segments of the left stem were documented as smaller and other larger as compared to Caucasians.
