Abstract
A review on percutaneous coronary intervention of chronic total occlusion in the non-ST elevation myocardial infarction cohort
Author(s): Sunil Thambi, Vinoda SharmaA Chronic Total Occlusion or (CTO), is defined as a 100 percent stenosis of a coronary artery with Thrombolysis in Myocardial Infarction (TIMI) 0 flow for more than three months. There is published data on the management of CTOs in an elective setting or with ST Elevation Myocardial Infarction (STEMI). However, the evidence is more conflicting when it comes to a CTO in the Non-ST Elevation Myocardial Infarction (NSTEMI) cohort. A recent six centre observational, retrospective study attempts to delineate the characteristics and outcomes of patients with CTO and NSTEMI. Patients in their cohort were older men with cardiovascular risk factors and worse in-hospital and long term outcomes. We review the existing literature on CTO in a NSTEMI cohort with specific reference to the above study
