Objective: Linkages of renin gene polymorphisms with hypertension have been implicated in several populations with contrasting results. Present study aims to assess the pattern of renin gene polymorphisms in Bangladeshi hypertensive individuals.Methodology: Introns 1, 9 of renin gene and 4063 bases upstream of promoter sequence of renin gene were amplified from the genomic DNA of the total 124 (hypertensive and normotensive) subjects using respective primers. Polymerase chain reaction-based restriction fragment length polymorphisms were performed using BglI, MboI and TaqI restriction enzymes.Results: Homozygosity was common in renin gene regarding BglI (bb=48.4%, Bb=37.9%, BB=13.7%, χ2 =1.91, P>0.05), TaqI (TT=81.5%, Tt=14.5%, tt=4.0%, χ2 =7.50, P<0.01) and MboI (mm=63.7%, Mm=32.3%, MM=4.0%, χ2=0.00, P>0.05) polymorphisms among total study population. For BglI and TaqI genotype distribution, hypertensive subjects (BglI: χ2 =6.66, P<0.05; TaqI: χ2 = 10.28, P<0.005) significantly deviate from Hardy-Weinberg Equilibrium law compared to normotensive subjects (BglI: χ2=0.51, P>0.05; TaqI: χ2=0.20, P>0.05). On the other hand, with respect to MboI polymorphisms of renin gene, only normotensive subjects deviate from the law (patients: χ2=1.28, P>0.05; vs controls: χ2=6.81, P<0.01). In the context of allelic frequency, common T allele was clearly prevalent (T frequency=0.86, t frequency = 0.14) for TaqI, but rare alleles b and m were more frequent for both BglI (b frequency=0.69, B frequency=0.31) and MboI (m frequency=0.80 M frequency=0.20) polymorphisms, respectively.Conclusion: Thus, we report that Bangladeshi hypertensive subjects did not show any distinct pattern of renin gene polymorphisms compared to their healthy control subjects with regard to their genotypic and allelic frequencies.

Background: Acute myocardial infarction (AMI) is a major cause of death worldwide with arrhythmia being the most common determinant in the post-infarction period. Identification and management of arrhythmias at an early period of acute MI has both short term and long term significance. Objective: The aim of the study is to evaluate the pattern of arrhythmias in acute STEMI in the first 48 hours of hospitalization and their inhospital outcome. Methods: A total of 50 patients with acute STEMI were included in the study after considering the inclusion and exclusion criteria. The patients were observed for the first 48 hours of hospitalization for detection of arrhythmia with baseline ECG at admission and continuous cardiac monitoring in the CCU. The pattern of the arrhythmias during this period & their in-hospital outcome were recorded in predesigned structured data collection sheet. Result: The mean age was 53.38 ± 10.22 years ranging from 29 to 70 years. Most of the patients were male 42(84%). Majority of the patients had anterior wall ( anterior, antero-septal & extensive anterior) myocardial infarction (54%). Sinus tachycardia in isolation was the most common arrhythmia observed in 36.8% of patients followed by sinus bradycardia (22.8%), ventricular tachycardia (19.3%), ventricular ectopic (12.3%),first degree AV block (5.3%), complete heart block and atrial ectopic 1.7% each. Tachyarrhythmias were more common in anterior wall myocardial infarction, whereas bradyarrhythmias were more common in inferior wall myocardial infarction. Among studied patients, 72% had favourable outcome , followed by acute left ventricular failure 10%, cardiogenic shock & lengthening of hospital stay 8% each and death 2%. Conclusion: The commonest arrhythmias encountered were sinus tachycardia followed by sinus bradycardia, ventricular tachycardia, ventricular ectopic, AV block and atrial ectopic. The incidence of mortality was 2%. University Heart Journal Vol. 16, No. 1, Jan 2020; 16-21

Coronary artery disease (CAD) is one of the leading causes of death in the world and also in Bangladesh. This study was carried out to evaluate that Serum uric acid is a prognostic tool in acute myocardial infarction. In this study, 108 AMI cases were enrolled. All the patients were treated and managed identically by conventional standard management protocol. During hospital stay, patients were assessed for any kind of clinical outcomes e.g good recovery, mortality and morbidity (acute LVF, cardiogenic shock, arrhythmia and heart block). Patients with higher serum uric acid (SUA>6.5mg%, Group-II) were compared with Patients with lower serum uric acid (SUA<6.5mg%, Group-I). In Group I (n=66), good recovery, morbidity and mortality were found in 43 (65.2%), 21 (31.8%), 2(3.0%) patients and in Group II (n=42), good recovery, morbidity, mortality were 13 (31%), 23 (54.8%) and 6 (14.3%) patients respectively. In group II patients having high Serum uric acid concentration had low good recovery but high morbidity and mortality compared to group I patients. In group I (n=66), good outcome and bad outcome was found in 43(65.2%), and 23 (34.8%) patients and in group II (n=42), those were in 13 (31%) and 29 (69%) patents. Logistic regression analysis of serum uric acid concentration of study subjects were done considering uric acid as independent variable but outcome as dependent variable. It was shown that the odds ratio of mortality was 5.38(95% CI p<0.007), odds ratio of morbidity was 4.10(95% CI p<0.001) and odds ratio of bad outcome was 4.67(95% CI p<0.001). This findings indicates a patient having high uric acid had 5.38 times increased mortality, 4.10 times increased morbidity and 4.67 times increased bad outcome than patients having low serum uric acid concentration.University Heart Journal Vol. 12, No. 1, January 2016; 8-11

Acute coronary syndrome is a lethal condition. Treatment modality and success mostly depend on time yielded since onset of symptoms. It is known for more than 30 years that delay between symptom onset and treatment of less than 60 min are desirable, but pre hospital delays remain unacceptably long worldwide including Bangladesh. A greater understanding of the contributing factors may help to reduce delays. A number of sociodemographic, clinical, social and proximal factors have been associated with pre hospital delay. The total pre hospital delay period consists of two component: time taken by patients to recognize that their symptoms are serious and to contact medical help (decision time) and the time taken from requesting help to admission where emergency coronary care is available (time to hospital delay). Different factors may affect these two components. In hospital delay also known as door-to-treatment, is defined as time from arriving to hospital to initiation of reperfusion therapy. Regardless of how to shorten in hospital delay, if the pre hospital delay is not reduced, then reperfusion therapy cannot achieve the best results. We set out to discover what factors are specifically associated with three components: decision time, home to hospital delay and First Medical Contact (FMC) to revascularization delay. This review may help the National health management system to identify the factors associated with treatment delay in ACS and thus reduces ACS related morbidity and mortality.
