流行病学“危险因素”虽未能解决冠心病的原因问题,但为病因研究和防治提供了重要线索。为了阐明“危险因素”的控制能否降低冠心病的发病率,不少国家的作者进行预防试验已多年,有的仍在继续中。大多时间较长,人数较多,有的是在WHO组织下多个国家或地区的合作研究。但已发表的资料结果不一,迄今未能得出结论。如Stamler报道在芬兰、芝加哥等处采取减轻体重、减少膳食中脂肪、减少吸烟等措
Although epidemiological “risk factors” can not solve the cause of coronary heart disease, it provides important clues for the study and prevention of etiology. In order to clarify whether the control of “risk factors” can reduce the incidence of coronary heart disease, many countries have conducted preventive trials for many years and some are still continuing. Most of the time is longer, the number is larger, and some are under the WHO organization of cooperative research in many countries or regions. However, the published information has mixed results and has so far failed to reach a conclusion. As reported by Stamler in Finland, Chicago and other measures taken to reduce weight, reduce dietary fat, reduce smoking and other measures
