NCT ID: NCT03613337 Recruiting - Clinical trials for Coronary Heart Disease

Effect of Smoking Status and Genetic Risk Factors on Restenosis and Efficacy of Clopidogrel After de Novo Percutaneous Coronary Intervention

Start date: May 1, 2018
Phase:
Study type: Observational

Restenosis occurs for many different reasons. Over the years, many predictive clinical, biological, genetic, epigenetic, lesion-related, and procedural risk factors for restenosis have been identified. Smoking is one of most important factors, however the results were contradictory. And the genetic factors of restenosis have been studied mostly in European populations. Based on literature review, study of candidate genes for restenosis in Chinese population was insufficient. With due attention to this matter mentioned above, the investigators aim to preliminary explore genetic variation and smoking effect on clinical restenosis in patients diagnosed with after percutaneous coronary intervention in the Chinese population, with correlation analysis of factors and gene-set analysis of biological pathways related to restenosis and platelet approach were widely used in this study.
