我们用多变量危险函数对引起冠心病危险因素进行综合定量以预测个体发生冠心病的危险性。 40岁以上健康人53名,40岁以上冠心病158例均按1979年全国冠心病座谈会修订标准确诊。测其血清胆固醇、血压、心电图、身高、体重,计算出每人的身高体重指数。用航空医学研究所提出的多变量危险函数计算每人的危险值。其方程式为t危险值=0.18×年龄(岁)+0.08×舒张压+0.01×胆固醇+0.40×体重指数+1.22×心电图(心电图数量化方法为:正常心电图为零,大致正常心电图为1,可疑心电图为2,不正常心电图为3)。判定方法为:危险值超过下列水平时判定为阳性。即冠心病危险组:50岁以下为18.50;51～60岁为20.00,大于60岁为23.30。 按上述方程式计算出各年龄组危险值的均值以及各年龄组的阳性人数,见附表:在107例心绞痛病人组中,心电图正常或可疑正常
We used a multivariate risk function to quantify the risk factors responsible for coronary heart disease to predict the risk of coronary heart disease in individuals. 53 healthy people over the age of 40, coronary heart disease over the age of 40 158 cases were diagnosed according to the revised standards of the 1979 National Coronary Heart Disease Symposium. Measurement of serum cholesterol, blood pressure, ECG, height, weight, calculate the height and weight of each person’s index. The risk value per person was calculated using the multivariate hazard function proposed by the Institute of Aeronautical Medicine. The equation for the value of t risk = 0.18 × age (years) + 0.08 × diastolic blood pressure + 0.01 × cholesterol + 0.40 × body mass index + 1.22 × ECG (ECG quantification method is: normal ECG is zero, the general normal ECG is 1, suspicious ECG 2, abnormal ECG 3). The judgment method is: the risk value is judged to be positive when exceeding the following levels. The risk of coronary heart disease group: 18.50 years of age below; 51 to 60 years old was 20.00, greater than 60 years of 23.30. According to the above equation to calculate the average risk value of each age group and the positive number of each age group, see Schedule: In 107 cases of angina patients, ECG normal or suspicious normal
