Abstract
Objective To study the influence of cigarette smoking on coronary blood flow in patients with normal coronary artery angiography. Methods One hundred and twenty three patients with normal coronary artery angiography were divided into smoking group (57 patients) and non-smoking group (66 patients) according to their cigarette smoking status. Thrombolysis in myocardial infarction (TIMI) frame counts of left anterior descending artery, left circumflex artery and right coronary artery and average TIMI frame counts of overall major coronary arteries were calculated. Analyzed the slowing of coronary blood flow and their related risk factors. Results TIMI frame counts of left anterior descending artery ( 41.43±15.29 vs 36.5±11.75, P＜0.05), left circumflex artery (29.48±9.95 vs 23.43±12.54, P＜0.05), right coronary artery (25.33±10.92 vs 20.63±11.28, P＜0.05) and average TIMI frame counts of overall major coronary arteries (31.23±13.11 vs 27.12±9.68, P＜0.05) in smoking group were significantly higher than those in non-smoking group. Smoking, obesity,diabetes mellitus and hyperlipidemia were the independent risk factors of slowing of coronary blood flow. Conclusions In smokers, coronary blood flow was impaired despite the morphology of coronary artery remains in normal range.关键词
