Brief Summary

Coronary intermediate lesions generally refer to lumen narrowing with diameter stenosis% (DS%) between 50% and 70% on angiography. Prognosis varies significantly among patients with intermediate lesions, and some lesions progress rapidly leading to adverse cardiovascular events. Therefore, accurate risk stratification is important and will help clinicians identify patients at high risk of adverse events. The aim of study is to identify independent risk factors for major adverse cardiovascular events (MACE) among patients with intermediate lesions. The study is a prospective, single-center, ongoing, observational study, which aims at enrolling approximately 1389 patients with intermediate coronary lesions. After enrollment, the following data are collected for each participant: baseline characteristics including demographics, clinical presentation, traditional risk factor, diagnosis and management; lesion characteristics assessed by coronary angiography; quantitative flow reserve; lab tests including blood chemistry, blood lipid, hemoglobin A1C, cardiac biomarker, BNP, et al. Patients are followed up at 2 year for primary outcome including death, myocardial infarction and repeat unplanned revascularization. A risk prediction score will be established and validated for major adverse cardiovascular disease at two-year follow-up.

Study Population

Patients suspected of CAD and underwent elective coronary angiogram. Patients have signed written informed consent.

You may qualify if:

  • Receiving elective coronary angiography
  • Written informed consent
