Clinical and Angiographic Characteristics, in Hospital and Short-Term Outcomes in Patients with ST Elevated Myocardial Infarction, Undergoing Primary Percutaneous Intervention

Abstract

Background: Acute myocardial infarction is considered one of the common causes of morbidity and mortality across the world.

Objectives: We aimed to evaluate baseline demographic/clinical, angiographic characteristics, in-hospital and short-term outcomes among patients with ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention.

Patients and Methods: Medical records of STEMI patients (n=57) were reviewed at Erbil Cardiac Center and were followed up prospectively, immediately and 1 month postoperatively (June-August 2022).

Results: The mean age of the patients was 57 (37-78 years). Smoking and hypertension were the most prevalent risk factors. The ECG findings revealed that the ST elevation was mostly of the inferior pattern followed by extensive anterior, anteroseptal, lateral, inferior-posterior, and anterolateral patterns, respectively. The study found that 23.58% had impaired ejection fraction before and after PPCI. The angiographic findings regarding the dominancy profile were the right dominant (74.53%), left dominant (21.70%) and co-dominant (3.77%). The most prevalent culprit coronary was LAD (proximal segment). Most of the patients had a grade 0 of TIMI flow (62.26%) followed by a grade of 3. The lesions were mostly >20 mm in length followed by 10-20 mm, and less commonly <10 mm, and mostly were non-angulated with irregular contours. The study showed that (39.62%) had mild calcification followed by moderate (24.53%) and severe (6.60%) and most patients had total occlusion. The patients had minor complications only four patients died and one patient failed PCI.

Conclusions: The study showed that STEMI patients who underwent PPCI have rather low complications, mortality
