简要总结
To describe the role of genetic factors and its relationship and interaction with environmental factors in the recurrence of cardiac events in Chinese patients with acute coronary syndrome.
详细描述
- Research cohort: Patients diagnosed with acute coronary syndrome are enrolled and to be followed up for 2 years.
- Baseline and follow up variables include patients' demographics, medical history, ACS event characteristics, clinical treatment options (interventional cardiology, drug therapy: antithrombotic therapy, other treatments recommended by guidelines ) and follow up events information.
- Blood Sample collection 4ml of vein blood will be drawed. Centrifugation of plasma and WBC will be done on-site within 30 minutes for DNA extraction. Samples will be stored at -80℃ freezer for subsequent applications.
- A nested case-controlled study is designed for the genetic analysis:
- Cases: Patients suffered from death, myocardial infarction, stroke and coronary revascularization and bleeding during the 2-year follow up. We expected to get 600 cases in the study cohort;
- Controls: among patients without any of the above events during follow, matched controls of 1:1 ratio will be selected according to date of admission (± 1 month), age (± 5 years), sex, baseline ACS diagnosis, whether treated with PCI , the same pattern of antithrombotic therapy and the study center.
- Genotyping Genotype testing using exome DNA chips (Exome Beadchip). Exome Beadchip is a high-throughput DNA chip designed by Illumina's, containing 240,000 SNP on exons in the genome that may lead to functional changes.
- Analysis:
- To analysis the impact of genetic characteristics on selection of treatment strategy in ACS patients, and its interaction with other baseline clinical variables.
- To analysis the impact of genetic characteristics on patient outcomes, and its interaction with clinical characteristics and management patterns.

入选标准
- •Written informed consent has been provided.
- •Contact Order Form has been provided.
- •Aged 18 years or older.
- •Diagnosis of STEMI, NSTEMI or UA using the following definitions:
- •Criteria for STEMI diagnosis:
- •History of chest pain/discomfort and
- •Persistent ST-segment elevation (> 30 min) of ≥ 0.1 mV in 2 or more contiguous ECG leads or presumed new left bundle branch block (LBBB) on admission and
- •Elevation of cardiac biomarkers (CK-MB, troponins): at least one value above the 99th percentile of the local laboratory upper reference limit.
- •Criteria for NSTEMI diagnosis:
- •History of chest pain/discomfort and
- •Lack of persistent ST-segment elevation, LBBB or intraventricular conduction disturbances and
- •Elevation of cardiac biomarkers (CK-MB, troponins): at least one value above the 99th percentile of the local laboratory upper reference limit.
- •Criteria for Unstable Angina diagnosis:
- •Symptoms of angina at rest or on minimal exercise and
- •At least 0.5mm ST deviation in at least 2 leads and
- •No increase in biomarkers of necrosis
- •OR objective evidence of ischaemia by non-invasive imaging OR significant coronary stenosis as determined by the treating physician at angiography if this is standard practice in study site.
- •Hospitalized within 48 hours of onset of symptoms.
排除标准
- •Patients will not be eligible to participate if any of the following exclusion criteria are present:
- •UA, STEMI and NSTEMI precipitated by or as a complication of surgery, trauma, or GI bleeding or post-PCI.
- •UA, STEMI and NSTEMI occurring in patients already hospitalized for other reasons.
- •Presence of any condition/circumstance which in the opinion of the investigator could significantly limit the complete follow up of the patient (e.g. tourist, non-native speaker or does not understand the local language, psychiatric disturbances).
- •Presence of serious/severe co-morbidities in the opinion of the investigator which may limit short term (i.e. 6 month) life expectancy.
- •Current participation in a randomised interventional clinical trial.
