Associations between ECG Changes and Echocardiographic Findings in Patients with Acute Non-ST Elevation Myocardial Infarction

Abstract

Background: STEMI shows specific ECG changes due to sudden coronary blockage, but NSTEMI has varied ECG characteristics, including ST depressions and T wave inversions. Echocardiography, especially tissue Doppler imaging and speckle tracking, is crucial for diagnosing and predicting outcomes in acute coronary syndrome. The study aims to correlate ECG changes with echocardiographic findings in NSTEMI, offering potential diagnostic insights. Objective: The study aims to connect ECG alterations with echocardiographic findings in NSTEMI patients. Methods and Materials: This cross-sectional study took place from January to June 2023 at a Mymensingh Medical College Hospital, Mymensingh, Bangladesh. The research included 109 NSTEMI patients, both with and without cardiac history. Inclusion criteria were age above 30 and ischemic type of chest pain. Results: Out of 109 admitted patients, 67.4% were male and 6.4% were female. The average age was 54.34 ± 2.31 years, and prevalent conditions included 7.3% with diabetes, 11% with dyslipidemia, and 0.9% with edema, while 73% had a family history of ischemia. Conclusion: There were inconsistencies between the ECG and Echo in identifying the site of the infraction in the MI patients. Pulmonary hypertension, infection, ischemic stroke, and inferonasal regional wall motion abnormalities. Maximum no association was found in ECG changes and echocardiographic findings with acute non-ST elevation myocardial infarction.
