冠状动脉正常的继发于高血压的左心室肥厚病人的心绞痛发生机制尚不了解。曾指出以下可能原因:冠状动脉储备量减少,冠状动脉造影不能显示的小冠状动脉闭塞,冠状动脉微血管发育不良或引起冠状动脉阻力的血管外成份增加。为进一步研究这个问题,本文对冠状动脉正常的高血压患者除作选择性冠状动脉造影及左室造影外,并测定了冠状
The mechanism of angina pectoris in patients with normal left ventricular hypertrophy secondary to hypertension is unknown. The following possible causes have been identified: decreased coronary artery reserve, small coronary arteries that can not be displayed by coronary angiography, impaired coronary microvascular or extravascular components that cause coronary resistance. In order to further study this problem, this article in addition to coronary artery normal hypertensive patients for selective coronary angiography and left ventricular angiography, and measured the coronal
