肌钙蛋白I(cTnI)为心肌损害的常规检测指标。晚近报道,它尚可预测伴不稳定冠心病(CHD)患者其继发急性心肌梗死或死亡风险将升高。而即使在无CHD临床佐证者,cTnI水平亦有伴随年龄增长而增高的趋势,既而提示在此类人群中亦显然存在无症状心肌损害。本文拟就基线无CHD老人中其cTnI水平与继发CHD及死亡风险大小间关系进行了分析。 Troponin I (cTnI) is a routine measure of myocardial damage. It has recently been reported that it is still predictive of an increased risk of secondary acute myocardial infarction or death in patients with unstable coronary heart disease (CHD). Even in patients with no clinical evidence of CHD, the level of cTnI also increases with age, which suggests that asymptomatic myocardial damage is also evident in these populations. This article intends to analyze the relationship between the level of cTnI and the risk of secondary CHD and risk of death in baseline CHD-free adults.
