Abstract
Objective To investigate the prognosis of patients with myocardial bridges diagnosed by 320-row coronary computed tomography angiography (CCTA). Methods Patients undergoing 320-row CCTA between August 2008 and December 2010 were enrolled and divided into normal coronary artery,coronary arte-rial plaque and myocardial bridge groups. All patients were followed up for the endpoint events including cardi-ac death,non-fatal acute myocardial infarction (AMI),unstable angina requiring hospitalization,and receiv-ing revascularization treatment due to myocardial ischemic symptoms and objective evidence and death from oth-er causes. The follow-up outcomes were subject to survival analysis. Results Eventually,326 patients,184 (43.6%)male,were eligible for subsequent follow-up,aged (66.6 ±1 1.8)years on average. In total,104 segments with myocardial bridges were identified,78.9%(82/104)occurring in the middle segment of the left anterior descending (LAD)artery. The myocardial bridges were distributed in 99 patients with a detection rate of 30.4%(99/326). Thirty six patients had simple myocardial bridges. Survival analysis showed that the sur-vival curves did not significantly differ between patients with simple myocardial bridges and those with normal coronary artery (P=0.441). The survival curve of patients with simple myocardial bridging did not significant-ly differ from that of their counterparts with coronary arterial plaque (P>0.0167),whereas a divergent trend was noted between two groups. Conclusion Patients with simple myocardial bridges diagnosed by 320-row CCTA have good clinical prognosis.关键词
