目的 利用心肌灌注断层显像 ,探讨高血压患者心肌灌注的情况。方法 对 47例高血压患者、1 6例对照组进行心肌灌注断层显像 ,并分析其心肌灌注断层显像结果。结果 高血压组患者心肌缺血阳性率 (66% )显著高于对照组 1 2 .5% (P<0 .0 0 5) ;高血压组心梗发生率 2 3.4% ,显著高于对照组 ,(P<0 .0 5) ;高血压组内心肌缺血患者中吸烟者的比例为 71 % ,显著高于不吸烟者的 2 5% ,(P<0 .0 0 5)。结论 高血压患者较易并发心肌缺血和心梗 ,吸烟是其危险因素
Objective To investigate myocardial perfusion in hypertensive patients by myocardial perfusion tomography. Methods Myocardial perfusion imaging was performed on 47 hypertensive patients and 16 control subjects. The results of myocardial perfusion tomography were analyzed. Results The positive rate of myocardial ischemia (66%) in hypertension group was significantly higher than that in control group (12.5%) (P <0.05). The incidence of myocardial infarction in hypertensive group was 23.4%, significantly higher than that in control group (P <0.05). The proportion of smokers in hypertensive patients with myocardial ischemia was 71%, which was significantly higher than that of non-smokers (P <0.05). Conclusion Patients with hypertension are more likely to have myocardial ischemia and myocardial infarction. Smoking is a risk factor
