在经冠状动脉造影确诊的男性冠心病与非冠心病者间进行小、中量吸烟与冠心病关系的病例对照研究,结果为:男性小、中量吸烟不增加发生冠心病的危险性,与冠脉病变程度间亦无剂量效应关系。经与其他冠心病危险因素的分层分析后表明,小、中量吸烟与冠心病的发生依然无关。 A case-control study on the relationship between small and medium-amount smoking and coronary heart disease among men with coronary heart disease and non-coronary heart disease diagnosed by coronary angiography showed that the risk of coronary heart disease was not increased There was no dose-effect relationship between the degree of coronary artery lesion. After stratified analysis with other coronary heart disease risk factors, small and medium-sized smoking still has nothing to do with the occurrence of coronary heart disease.
