Transcriptome Study of Acute Myocardial Infarction

Beijing Institute of Heart, Lung and Blood Vessel Diseases

Status: Unknown

Conditions: Acute Myocardial Infarction

Study type: Observational

Funder types: Other

Identifiers

NCT03158597

Details and patient eligibility

About

This study aims to compare whole-blood microarray gene-expression profiling between patients with acute myocardial infarction and normal participants without cardiovascular diseases. Firstly, screening differentially genes of mRNA to perform gene ontology and pathway analysis. Secondly, predicting target genes regulated by microRNA and constructing coexpression network with mRNA. Thirdly, biological function experiment of microRNA. Finally, revealing pathogenic mechanisms associated with acute myocardial infarction.

Enrollment: 20 estimated patients
