Brief summary
The primary objective of this study is to determine whether coronary computed tomography angiography (CCTA) -based coronary heart disease(CHD) prevention strategy improves lipid-lowering treatment and cardiovascular risk factor control compared with traditional CHD prevention strategy, guided by a cardiovascular risk score.
Detailed description
At present, doctors usually use a risk score to identify people at risk of heart disease who may benefit from medical treatment. In the RESPECT study the investigator will compare this risk score to coronary CTA scan. In this study the investigator would like to determine the effect of coronary CTA scan on lipid-lowering treatment and cardiovascular risk factor control. This study will recruit 3400 eligible community volunteers (asymptomatic individuals free of any known cardiovascular event) aged 40 to 69 years, then, randomized (1:1) them to receive individualized primary prevention programs for coronary heart disease based on CCTA results or traditional risk score, as recommended in the Chinese CVD prevention guidelines. The intervention strategies in this study are consistent with RESPECT trial. The investigator will assess the difference of lipid-lowering treatment and cardiovascular risk factor control between two groups 12 months later. Furthermore, the investigator will present the results of subclinical coronary atherosclerosis in participants who have undergone coronary CTA scans. This will help us understand the prevalence of subclinical coronary atherosclerotic disease in an asymptomatic Chinese population.
