目的:分析核素心肌灌注断层显像在诊断高血压患者心肌缺血及心梗的临床应用。方法:对69例高血压患者、26例对照组进行心肌灌注断层显像,并分析其心肌缺血及心梗的结果。结果:高血压组患者心肌缺血阳性率66.67%显著高于对照组15.38%(P<0.05);高血压组心梗发生率27.53%,显著高于对照组3.85%(P<0.05);高血压组心肌缺血患者中吸烟的比例为84.78%,显著高于不吸烟者的26.09%(P<0.05)。结论:高血压患者易并发心肌缺血和心梗,吸烟是其重要的危险因素。
Objective: To analyze the clinical application of radionuclide myocardial perfusion tomography in the diagnosis of myocardial ischemia and myocardial infarction in hypertensive patients. Methods: Myocardial perfusion imaging was performed on 69 hypertensive patients and 26 control subjects. The myocardial ischemia and myocardial infarction were analyzed. Results: The positive rate of myocardial ischemia in hypertension group was 66.67%, which was significantly higher than that in control group (15.38%, P <0.05). The incidence of myocardial infarction in hypertension group was 27.53%, significantly higher than that in control group (3.85%, P <0.05) In the blood pressure group, the percentage of smoking in patients with myocardial ischemia was 84.78%, which was significantly higher than that in non-smokers (26.09%, P <0.05). Conclusion: Hypertensive patients complicated with myocardial ischemia and myocardial infarction, smoking is an important risk factor.
