人类高血压所致左室肥厚对冠脉侧支循环的影响尚未阐明。为此作者选右冠或左前降支管腔狭窄≥95％的冠心病患者313例,分为高血压组61例,平均55±9岁,血压正常组平均53±8岁。用超声心动图连续测量三个以上心动周期的左室壁厚度,取其平均值,以冠脉造影狭窄最明显的投影计算管径狭窄的百分数。按对侧冠脉注射造影剂后心外膜冠脉充盈的有无和范围分级:0级无心外膜充盈;I级仅边缘支充盈;II级心外膜段部分充盈;III级心外膜段全部充盈。结果高血压组比正常血压组心绞痛较
Left ventricular hypertrophy caused by human hypertension on coronary collateral circulation has not yet been clarified. To this end, the author selected 313 patients with coronary heart disease whose right coronary artery or left anterior descending coronary artery stenosis ≥ 95%. The patients were divided into hypertension group (61 cases), average 55 ± 9 years old and mean normal blood pressure group (53 ± 8 years). The left ventricular wall thickness of three or more cardiac cycles was continuously measured by echocardiography and the average was taken to calculate the percentage of stenosis with the most obvious projection of coronary angiography stenosis. According to the contralateral coronary injection of contrast agent after epicardial coronary filling with and without the scope of the grading: 0 no adventitia filling; I only marginal filling; Class II part of the epicardial filling; grade III epicardial Section full filling.
