Target Vessel Versus Complete Revascularization in Non-ST Elevation Myocardial Infarction Without Cardiogenic Shock

Introduction The role of complete revascularization (CR) vs target vessel revascularization (TVR) in non-ST-elevation myocardial infarction (NSTEMI) in patients without cardiogenic shock is still not established. In this study, we compared outcomes at one and six months among patients with NSTEMI wi...

Description
Summary:Introduction The role of complete revascularization (CR) vs target vessel revascularization (TVR) in non-ST-elevation myocardial infarction (NSTEMI) in patients without cardiogenic shock is still not established. In this study, we compared outcomes at one and six months among patients with NSTEMI with multivessel disease (MVD) undergoing CR vs TVR. Methods It was a prospective, observational study carried out among 60 NSTEMI patients with MVD (30 undergoing TVR and 30 CR) from October 2018 to November 2019. They were assessed at one and six months for primary and secondary outcomes. Results The mean age of the patients was 56.13 ± 9.23 years and both the groups were well matched with respect to age, gender, risk factors, and comorbidities. In the majority of patients, the target vessel was left anterior descending (LAD) followed by right coronary artery (RCA) and left circumflex (LCX) in both groups. The primary outcomes of death from any cause, non-fatal myocardial infarction, and the need for revascularization of the ischemia-driven vessel showed no significant difference at one and six months follow-up between the CR and TVR groups. However, the secondary outcomes of heart failure hospitalizations and angina episodes were significantly more in the TVR group than CR group at one month (6 vs 1, P=0.044), (8 vs 2, P=0.038) and six months (8 vs 2, P=0.038), (9 vs 2, P=0.02), respectively. Conclusion CR was associated with no difference in death from all-cause or future revascularization but significantly lesser secondary outcomes of heart failure hospitalizations and angina episodes as compared to TVR in NSTEMI without cardiogenic shock.
