摘要
目的:分析冠状动脉迂曲患者的临床特点和迂曲血管分布以及左心舒张功能受损之间的关系。方法:运用640层螺旋CT检查出47例冠状动脉血管成像无明显狭窄而有冠状动脉迂曲患者,并进行超声心动图检查。结果:47例冠状动脉迂曲患者,男22例,女25例,合并高血压有35例,共发现141段迂曲血管段,25例轻度,19例中度,3例重度,以前降支远段、回旋支远段、左室后支多见。左心室舒张功能减退者38例,E/A<1的38例,E/A=1的7例,E/A>1的2例。结论:冠状动脉迂曲与高血压有一定关系,迂曲血管主要分布于左心室心肌供血动脉,冠状动脉迂曲患者多有左室舒张功能减退,两者共同作用导致冠状动脉血流储备能力下降,是患者出现类似冠心病症状的重要原因。
Objective： To analyse the clinical characteristics of patients with coronary artery tortuosity and the relationship between tortuous vascular distribution and impaired left ventricular diastolic function. Methods： Forty-seven cases of coronary artery angiography patients with undefined stenosis and coronary artery tortuosity were detected by 640 multi-detector spiral CT and echocardiography. Results： Forty-seven cases of coronary artery tortuosity patients, including 22 cases of males and 25 cases of females, accompanied with hypertension of 35 cases, 141 cases of tortuous vascular segments were found, includ- ing 25 mild, 19 moderate and 3 severe, and often occurred in distal segment of left interior descending, distal segment of circumflex artery, left ventricular posterior branch. The left ventricular diastolic function were impaired in 38 patients, includ- ing 38 cases of E/A〈1, 7 cases of E/A=1, and 2 cases of E/A〉1. Conclusion： There is a certain relationship between coro- nary artery circuity and hypertension. Circuitous blood vessels are mainly occurred in feeding arteries of the left ventricular myocardial, and many patients with coronary artery circuity combined with decreased left ventricular diastolic function. The two reasons result in a poor capacity of coronary blood flow reserve, which is an important reason for the patients with similar symptoms of coronary heart disease.
