在1亿6千万20岁以上的美国人中,大约有6千万人(37%)的体循环动脉收缩压>140mmHg 及/或舒张压>90mmHg。世界卫生组织将高血压定为收缩压>160mmHg 及/或舒张压>95mmHg;本文则以收缩压>140mmHg 及/或舒张压>90mmHg 定为高血压。冠心病猝死:死于冠状动脉疾病(CAD)的患者中,大约50%为猝死;在症状性 CAD 中,大约25%病例以猝死为冠心病的首发结局。据 Kuller 等报
Of the 160 million Americans over the age of 20, about 60 million (37%) have systolic arterial systolic blood pressure> 140 mmHg and / or diastolic blood pressure> 90 mmHg. WHO defines hypertension as systolic> 160 mmHg and / or diastolic> 95 mmHg; herein, hypertension is defined as systolic> 140 mmHg and / or diastolic> 90 mmHg. Sudden death from coronary heart disease: About 50% of patients who die of coronary artery disease (CAD) are sudden death; in symptomatic CAD, about 25% of sudden deaths are the first outcome of coronary heart disease.
