Abstract
Tissue Doppler imaging is a breakthrough in cardiology. It is well established as safe, non invasive, and versatile diagnostic modality, and is now a predominant technique used for the evaluation of left ventricular function, for the assessment and quantification of valvular heart lesions and the quantification of ischemia-induced regional myocardial dysfunction.
Aim: The present study was carried to investigate whether various admission electrocardiogram patterns of acute anterior wall myocardial infarction can be associated with distinct pattern of regional wall motion abnormalities as detected by trans-thoracic echocardiography and Tissue Doppler Imaging (TDI).
Patients and methods: The study included thirty patients with diagnosis of first time acute anterior myocardial infarction. All patients underwent 12-lead ECG, echocardiography to measure the WMSI and EF and pulsed wave TDI for the measuring of the longitudinal velocity of the systolic shortening (S wave) of the segments affected.
Results: The mean age was 52.8 years ± 11.3. Males comprised 73.33% of the sample size and all of them were smokers. 23 patients were diagnosed having anterior STEMI (76.7%) and 7 patients were diagnosed having anteroseptal STEMI (23.3%). The mean total CPK on admission of all patients was 954.1 ± 705.6. The mean EF% was 45.2 ± 11.7 and the mean WMSI was 1.48 ± 0.19 of all patients. The mean S wave of all segments was 2.5 ± 2.1. The mean S wave of the patients with anterior STEMI was 2.16 ± 1.17 and of patients with anteroseptal STEMI was 3.54 ± 1.24. When segmental wall motion score index and EF was correlated, there was a significantly negative relationship between EF% and WMSI. The mean S wave was significantly positively related with the mean EF%. The mean S wave was significantly negatively related with the mean WMSI.
