ABSTRACT
Background: It is a new pandemic; the demographic profile of COVID-19patients may be helpful for corona virus patients. Methods: This was a cross-sectional study conducted at the department of cardiology at Rangpur medical college hospital, Rangpur, Bangladesh during July 2020 to December 2020.In total 37confirmed COVID-19patients were selected as the study population. Data were collected from patients or their attendants by using a pre-designed structured questionnaire, after having appropriate consent. The statistical package for the Social sciences (SPSS) version 22.0 was used for data analysis. Results:In this study 70% participants were male whereas 30% were female and the ratio was 2.36:1. The mean±SDage of the participants was 56.57±15.96 years. The highest number of participants were from 51-60 years’ age group which was 27.3%, 2.70%, 18.92%, 16.22%, 13.51%, and 21.62% participants were from 21-30, 31-40, 41-50, 61-70 and >70 years of age group respectively. The majority portion of participants were with normal body-weight (BMI: 18.5-24.9) which was in 57% and 43% were with overweight (BMI: 25.0-29.9). More than half of the patients were from Rangpur district which was 54%. The highest number of patients were with cough as a major symptom, which was 51.35%. The highest number of participants were with IHD (64.86%) as a major comorbidity. Conclusions:As per the findings of this study, we can conclude that, middle aged population are mostly being affected byCOVID-19in Bangladesh. The affected number of males were higher than female.
ABSTRACT
The complications, therapy and prognosis are significantly determined by the exact location of occlusion site in left anterior descending (LAD) coronary artery in anterior acute myocardial infarction (AMI). This study assessed the role of Electrocardiogram (ECG) as a predictor of coronary artery occlusion site in anterior AMI. Sixty two patients of anterior AMI were divided into two groups according to the occlusion site in relation to first septal and first diagonal branches, proximal--group A and distal--group B. Their initial ECG were analyzed and interpreted. The number of patients having ST elevation in leads aVR and aVL (> or = 0.5 mm) were significantly higher in proximal group compared to distal ones (42.3% vs 2.8% and 73.1% vs 22.2%; p < 0.001). Similarly the number of patients having ST depression in inferior leads, II (> or = 1 mm), III (> or = 1 mm) and aVF (> or = 1 mm) were also significantly higher in proximal group (84.6% vs 22.2%, 88.5% vs 33.3% and 84.6% vs 22.2%; p < 0.001). The sensitivity of ST depression in inferior leads II (> or = 1 mm), III (> or = 1 mm) and aVF (> or = 1 mm) to predict the proximal lesion were 85.0%, 88.0% and 85.0% respectively, whereas specificity were 78.0%, 67.0% and 78.0% respectively. The ST elevation in a VR had 42.0% sensitivity and 97.0% specificity to predict proximal lesion. Similarly ST elevation in aVL (> or = 0.5 mm) had 73% sensitivity and 78% specificity. In anterior AMI, ST elevation in aVR, aVL and ST depression in inferior leads can predict the occlusion site in LAD proximal to first diagonal and first septal branch.
