虽然心脏病的死亡率连续下降,医学研究人员仍在寻求检测、治疗和预防这种在美国居于首位死亡原因疾病的新方法。在美国心脏病协会举行的科学年会上,专家们讨论了以下一些新的进展。运动试验心脏病发作后三周做标准运动试验,能使医生预测下一次发作的危险性,鉴别哪些病人发作的危险性很小,不需要药物或外科治疗,并能安全地恢复工作。斯坦福大学医学院对有过心脏病发作的1,000名男性存活患者进行了为期十年的研究。能做完踏车试验的病人(约占50％)中,下一次发作时可能死 Despite the continuous decline in heart disease mortality, medical researchers are still seeking new ways to detect, treat and prevent this first-leading cause of death in the United States. At the Scientific Annual Meeting of the American Heart Association, the experts discussed some of the new developments below. Exercise Testing Three weeks after a heart attack, a standard exercise test will allow doctors to predict the risk of the next attack, identify which patients have a low risk of seizure, do not need medication or surgical treatment, and be able to safely resume their work. Stanford University School of Medicine conducted a 10-year study of 1,000 men who survived a heart attack. In patients who can complete the treadmill test (about 50%), the next attack may die
