Abstract
In STEMI patients, the presence of CTO in non-IRA has been associated with worse prognosis and adverse outcomes in many studies, whether in the short term or long term. This has been thought to be due to many factors including more major comorbidities in CTO patients, higher ischemic burden, and the “double Jeopardy theory”.
The aim of our study is to evaluate the incidence of in-hospital MACE in patients presenting with STEMI and CTO in non-IRA. We analyzed 111 patients (52 patients with CTO in non-IRA and 59 without CTO in non-IRA) to compare their clinical outcomes in Ain Shams
University hospitals.
Although it was not found to be statistically significant, we did find that the incidence of In-hospital MACE is higher in cases with CTO in non-IRA in comparison to cases without CTO in non-IRA including single vessel disease patients and multi-vessel disease patients. Acute Pulmonary Edema and Cardiogenic Shock were found to be significantly higher in cases with CTO in non-IRA. 50% of cases with CTO developed MACE; and 100% of the CTO cases that developed MACE had reduced ejection fraction.
