Short-term Treatment Outcome of Patients with Acute ST-elevation Myocardial Infarction in a Tertiary Care Hospital

Outcome of acute ST-elevation myocardial infarction patients varies time to time. The present study was intended to find out the short-term treatment outcome of the patients admitted in hospital. This descriptive study was carried out in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from 15 January 2014 to 14 July 2014. A total of 100 patients admitted with Acute ST-elevation Myocardial Infarction confirmed on the presence of the (a) Typical chest pain of acute ST-elevation Myocardial Infarction (b) Electrocardiogram (ECG) evidence of ST segment elevation in two or more contiguous leads (c) Raised cardiac marker (Troponin I) were included in the study. Patients were randomly enrolled according to the inclusion and exclusion criteria and observe for one week. Data were processed and analyzed by using computer bases software SPSS version 19.0. Descriptive statistical methods were applied for data analysis. P value was considered as statistically significant when it is less than 0.05. Short-term treatment outcome of acute ST-elevation myocardial infarction include mechanical, arrhythmic, ischemic and inflammatory sequelae, as well as left ventricular mural thrombus. In addition to these broad categories, heart failure, arrhythmia, death are other common complications of AMI. The initiation of the complications usually results in explicit sign and symptoms of the acute MI patients. Learning of the complications in the post infarction period and the clinical syndromes develop with each complication, will allow the health care worker to evaluate and manage the complication appropriately.

Association of Aortic Valve Sclerosis with Angiographic Severity of Coronary Artery Disease in Patients with Acute Coronary Syndrome, Aged ≤65 Years

Aortic valve sclerosis (AVS) represents a degenerative process that progresses with advancing age. The study was intended to find out the association between aortic valve sclerosis and the severity of CAD in patient's age ≤65 years with acute coronary syndrome. This cross-sectional analytical study was carried out in the department of cardiology, National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh during a period of October 2017 to September 2018. A total of 140 Acute coronary syndrome (ACS) patients undergoing coronary angiogram during index hospitalization were included in the study. Study patients were divided into two groups on the basis of echocardiographic presence or absence of Aortic valve sclerosis (AVS), with 70 patients in each group. Group I was patients with aortic valve sclerosis and Group II was patients without aortic valve sclerosis. All patients underwent transthoracic echocardiography before they underwent coronary angiography on different days. Severity of CAD was determined by Gensini score and Vessel score. Association of traditional risk factors (smoking habit, hypertension, diabetes mellitus, dyslipidaemia and family history of CAD) with severity of CAD was investigated. Coronary angiography showed that AVS group had a higher positive rate of CAD (82.9% vs. 54.3%, p<0.001) and incidence rate of triple vessel CAD (40% vs. 14.3%, p<0.001) than non-AVS group. Gensini score had higher in AVS group than non AVS group (37.9±27.8 vs. 12.5±14.2; p<0.001). Multivariate analysis showed that AVS (p=0.01) and age (p=0.04) were independent predictors of the presence of significant coronary artery disease. The study concluded that echocardiographically detected AVS is an independent predictor of coronary artery disease severity. There is positive correlation between severity of AVS and severity of CAD in patient's age ≤65 years with ACS.

Association of Diastolic Dysfunction with Angiographic Severity of Coronary Artery Disease in patients with Non-ST Elevation Myocardial Infarction

In recent years, diastolic dysfunction is an evolving context. Presence of left ventricular diastolic dysfunction (LVDD) indicates a poor prognosis in patients with an ACS and chronic coronary artery diseases. This study evaluated the association of LVDD and angiographic severity of CAD in patients with non-ST elevation myocardial infarction (NSTEMI). This cross-sectional analytical study was carried out in National Institute of Cardiovascular Diseases, Dhaka, Bangladesh, during the period of April 2017 to March 2018. A total of 120 NSTEMI patients undergoing coronary angiogram (CAG) during index hospitalization were included in the study. All patients underwent transthoracic echocardiography before they underwent CAG on different days. Presence (Group I, n=65) and absence of LVDD (Group II, n=55) was established by echocardiography. Severity of CAD was assessed by Vessel score and Leaman score. Association of traditional risk factors (smoking habit, hypertension, diabetes mellitus, dyslipidemia and family history of CAD) with severity of CAD was investigated. Vessel score showed coronary artery obstruction (CAO) was present in 62(95.4%) patients in Group I and 35(63.6%) patients in Group II, single vessel was involved in 17(27.4%) patients while multi vessel in 45(72.6%) patients was found in Group I. On the contrary 27(77.1%) single vessel patients and 8(22.9%) multi vessel patients were found in Group II. Positive Leaman score was significantly higher in Group I, 62(95.4%) than that of Group II, 35(63.6%) which is statistically significant (p<0.001). This study showed a positive correlation between LVDD and CAD severity in terms of vessel score and Leamanscore. This study also demonstrates that the severity of vessel score and Leaman score was higher in the higher grade of diastolic dysfunction. The present study concludes that LVDD is associated with angiographically severe CAD in patients with NSTEMI.
