心肌灌注显像与冠状动脉钙化积分对冠心病风险评估的研究现状及相互关系

The progress of interrelationship between myocardial perfusion imaging and coronary artery calciumscore in cardiac risk assessment

冠心病是严重威胁人类健康的常见病和多发病。早期诊断冠心病，无创、准确地进行心脏不良事件的风险评估并及时干预，是亟待解决的临床问题。风险评估模型对于心脏风险评估的有效性虽已被众多临床试验所证实，但仍有局限性。心肌灌注显像及冠状动脉钙化积分以及两者结合，为冠心病诊断及心脏风险的评估提供了新的思路。

Coronary heart disease （CHD） is a common and frequently occurring disease which seriously threaten the healtb of bmnan beings. So diagnosing CHD early and assessing the cardiac risk accurately and non-iuvasively that is a clinical problem which is urgent need for solving. Although the effectiveness of risk assessment algorithms have been proved by lots of clinical trials, but still has some limitations. The combination of myocardial perthsion imaging and coronary artery calcium score is promising in CHD diagnosis and cardiac risk assessment.
