Occluded Coronary Artery among Non-ST Elevation Myocardial Infarction Patients in Department of Cardiology of a Tertiary Care Centre: A Descriptive Cross-sectional Study

Abstract

Introduction: Non-ST elevation myocardial infarction is frequently thought to be caused by incomplete blockage of the culprit artery, whereas ST elevation myocardial infarction is frequently thought to be caused by total occlusion of the culprit artery. The objective of the study was to find out the prevalence of occluded coronary arteries among non-ST elevation myocardial infarction patients department of cardiology of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among non-ST elevation myocardial infarction patients in a tertiary care centre from 22 June 2020 to 21 June 2021 after taking ethical approval from the Institutional Review Committee [Reference number: 4271 (6-11) E2 076/077]. A total of 196 patients were included in the study by simple randomized sampling. Data on the patient’s clinical profile, angiographic findings, and in-hospital complications were recorded. Point estimate and 95% Confidence Interval were calculated. Results: Among 126 non-ST elevation myocardial infarction patients included in the study, the prevalence of occluded coronary artery was 41 (32.54%) (24.36-40.72, 95% Confidence Interval). Conclusions: The prevalence of occluded coronary arteries was similar to the studies done in similar settings.

Clinical Implications of High-Sensitivity Troponin Elevation Levels in Non-ST-Segment Elevation Myocardial Infarction Patients: Beyond Diagnostics

“…In this study, a retrospective analysis of 208 NSTEMI patients in a large university center established the predictive capacity of hs-cTnI concerning angiographic findings of coronary stenosis > 70% in the culprit vessel. Notably, over 95% of patients in this sample had one of the coronary vessels responsible for NSTEMI, emphasizing the challenge of discriminating the location of the culprit vessel with subendocardial ischemia [27]. This data is very interesting because it is similar to other reports where achieving identification of a culprit artery through angiography study is possible in more than 70% of cases analyzed [28,29], including intracoronary imaging strategies [30,31].…”

Determination of the infarct‐related artery in patients with myocardial infarction without ST segment elevation

“…Согласно исследованиям, около четверти ИМбпST вызвано полной окклюзией инфарктсвязанной артерии, что соответствует данным ИМпST при коронарной ангиографии [7]. У пациентов с ИМбпST по сравнению с пациентами с подъёмом сегмента ST идентификация инфарктсвязанной артерии (ИСА) может быть сложной задачей, поскольку у пациентов с большей вероятностью будет или многососудистое поражение, или незначительная ИБС.…”
