Pre-warning Risk Scoring System for Sudden Cardiac Death
Trial Parameters
Brief Summary
The goal of this observational study is to identify potential indicators for pre-warning of sudden cardiac death (SCD), including clinical biochemistry markers, electrocardiogram, echocardiography, MRI and CT imaging values, genetic markers and so on, and further construct a series of multi-parameter assessments of SCD early screening.
Eligibility Criteria
Inclusion Criteria: The subjects with the following diagnosis of one or more cardiovascular diseases: 1. Coronary heart disease If there is a history of coronary heart disease or a new diagnosis of coronary heart disease, or with a report of coronary angiography that indicates at least one vascular stenosis\>50%. Diagnosis includes chronic coronary syndrome (stable angina, ischemic cardiomyopathy, and occult coronary heart disease) and acute coronary syndrome (unstable angina, ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction). 2. Heart failure Individuals with a history of heart failure or newly diagnosed heart failure, including heart failure with reduced ejection fraction (HFrEF, left ventricular ejection fraction (LVEF) ≤40%)、intermediate heart failure (HFmrEF, LVEF 41%-49%，with evidence of spontaneous or excitable increase in left ventricular filling pressure), and ejection fraction preserving heart failure (HFpEF, LVEF≥50%, there is evi
