【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/A1的38例,E/A=1的7例,E/A1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。
[Abstract]:Aim: to analyze the relationship between the clinical features, the distribution of tortuous vessels and the impaired left ventricular diastolic function in patients with coronary artery detour. Methods: Sixty-four slice spiral CT was used to detect 47 patients with coronary artery detour without obvious stenosis and echocardiography. Results there were 47 cases of coronary artery detour, including 22 males, 25 females and 35 patients with hypertension. A total of 25 patients with 141 segmental tortuous vascular segments were found to be mild or severe in 19 patients. The anterior descending branch, distal circumflex branch, and posterior left ventricular branch were more common than those in the anterior descending branch, the distal circumflex branch and the posterior left ventricular branch. Left ventricular diastolic dysfunction was found in 38 cases of E / A 1 and 7 cases of E / A 1 and 2 cases of E / A 1. Conclusion: there is a certain relationship between coronary artery detour and hypertension. The tortuous vessels are mainly distributed in the left ventricular myocardial supplying artery, and the left ventricular diastolic function is decreased in the patients with coronary artery detour. The combined action leads to the decrease of coronary blood flow reserve, which is an important cause of coronary heart disease symptoms.
