About

Trimethylamine-N-oxide (TMAO) is produced from the metabolism of gut microbiota and is reportedly pro-atherogenic and associated with cardiovascular events. The purpose of this study is to investigate the sequential change in TMAO levels by current optimal secondary prevention therapies in patients with ST-elevation acute myocardial infarction (STEMI) and the clinical impact of TMAO levels on the progression of atherosclerosis and subsequent cardiovascular events.

Full description

This study includes patients with their first STEMI. The investigators measure plasma TMAO levels using the frozen plasma at the onset of STEMI and 10 months later (the chronic phase). To assess plaque progression, residual SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score and chronic-phase SYNTAX score are measured. After the chronic-phase assessment of TMAO and SYNTAX score, patients are followed for cardiovascular events including death, myocardial infarction, ischemic stroke, and unstable angina pectoris with coronary revascularization.

Enrollment: 112 patients

Sex: All

Ages: 20 to 100 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients who admitted to the Yokohama City University Medical Center with the diagnosis of their first STEMI and who underwent primary percutaneous coronary intervention within 12 hours after onset and received follow-up coronary angiogram 10 months after the index intervention.
