A Coronary Computed Tomography Angiography-guided Intervention for High Risk Cardiovascular Disease Population in Rural China
brief summary
The CARDIAC trial is a prospective, parallel, open-label cluster randomized trial that aims to determine the effectiveness of a coronary computed tomography angiography (CTA)-guided intensive intervention strategy, as compared with standard care, on reducing the incidence of major adverse events (MACE) at 18 months among high-risk cardiovascular populations in rural China. An extended observational follow-up at 36 months will be conducted to further evaluate the effect on long-term clinical outcomes.
detailed description
The CARDIAC trial aims to determine the effectiveness of a coronary CTA-guided intensive intervention strategy, as compared with standard care, on improving clinical outcomes among population at high risk for cardiovascular disease in rural China. This cluster randomized trial will be conducted in 428 rural villages in China. The study will recruit 35 individuals at high risk for cardiovascular disease from each village for a total of 14,980 participants. The participating villages will be randomly assigned to experimental group (CTA-guided group) and control group (standard care group) with 1:1 allocation. Study participants will be followed at 1, 3, 6, 12, and 18 months. The primary outcome is major adverse cardiovascular events (MACE, a composite of all-cause death, non-fatal myocardial infarction, and non-fatal stroke) at 18 months. In addition, an extended observational follow-up will be conducted at 36 months, to evaluate long-term outcomes (i.e., MACE).
