THE EFFECTS OF BETA BLOCKERS IN ENJECTION FRACTION OF MYOCARDIAL INFRACTION PATIENT

Myocardial infarction (MI) is a major health problem, with relatively high rates of morbidity and mortality. Beta blockers have been demonstrated to improve the long-term prognosis post-MI in terms of mortality and sudden cardiac death. This study was designed with the aim to provide information about the benefits of beta-blockers at improvement of ejection fraction in patients with myocardial infarction. The present study is one of the first echocardiographic studies of patients treated with beta blockers for myocardial infarction focusing on ejection fraction. Study was carried out in Sudan Heart Center, in between July 2012 to June 2014. Study population comprises A total of 67 adults patient who underwent cardiac ultrasound scanning were enrolled in this prospective study. (52; 77.6% males and 15; 22.4% females) and aged 33 to 86 years; mean age of 64 ± 14.67 years. Echocardiography studies were performed using Esaote echocardiography System (My Lab 50 Vision, Italy) with Phased array probe, convex face with small footprint for \"peeking\" in between rib interspaces (2.5 MHz). The mean and standard deviation (SD) of LVEF before prescribed beta blockers was (43.10±4.2).After receive beta blockers the mean and standard deviation (SD) of LVEF was (57.12±8.6) , T-Test for Paired Samples shows there is significant different effect between Two Variables . 48 patients had normal LVEF (>55%), 15 mildly reduced (45%–54%), and 4 moderately reduced (<44%). The result of this study shows significant increase in ejection fraction (p<0.001) after received beta blockers.
