Angiographic characteristics and cardiovascular risk factors of coronary artery aneurysm and coronary artery ectasia / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the differences of angiographic characteristics and cardiovascular risk factors of coronary artery aneurysm (CAA) and coronary artery ectasia (CAE). Methods Coronary angiographic data of 16 778 subjects were retrospectively analyzed. Results Coronary arteries dilatations were found in 211 patients, including 132 CAA (CAA group) and 79 CAE (CAE group). The morbidity of CAA, the concurrent morbidity of coronary heart disease (CHD) combined with CAA and Gensini score of CAA were all higher than that of CAE (all P<0.05). The average diameter of coronary arteries in patients with CAA was smaller than that in CAE patients (P<0.05), and thrombolysis in myocardial infarction (TIMI) was lower in CAA than CAE for all coronary arteries (all P<0.05). Dyslipidemia, smoking and family history of CHD were independent risk factors for CAA (all P<0.05). Conclusion: Significant differences of angiographic characteristics and cardiovascular risk factors exist between CAA and CAE.
