Background: Acute inferior ST-elevation myocardial infarction (STEMI) is medical emergency entailing immediate intervention to restore blood flow and mitigate myocardial damage. Primary percutaneous coronary intervention (PCI) has replaced thrombolytic therapy as preferred treatment strategy for having superior outcomes. Objectives: To develop a risk stratification model incorporating the identified predictors to estimate the individual risk of complete AV block in patients undergoing primary PCI for acute inferior STEMI. Methods: This study enrolled 139 patients diagnosed with acute inferior STEMI who underwent primary PCI at the hospital. They were divided into two groups, i.e. pre-operative and post-operative carrying 54 and 85 patients, respectively.  On admission, demographic, clinical data and peak values of cardiac biomarkers were obtained and the complications associated with PCI were elaborated. Results: Mean age of patients was 59.81+8.19 years, and comprised significantly more male (97) than female (42) patients (p<0.05). Proportion of patients with a history of complete AV block was 10.79%. Comorbidities included diabetes mellitus (33.09%), hypertension (49.64%), and dyslipidemia (64.74%).Coronary angiography findings for predicting AV block in patients with STEMI were categorized by location of culprit lesion in coronary vessels.

Objective: To determine frequency of glycemic control in patients with coronary artery disease (CAD) visiting to National Institute of Cardiovascular Diseases, Karachi. Study Design: Descriptive Cross-Sectional study Place and Duration: This study was conducted at Department of Cardiology, National Institute of Cardiovascular Diseases, Karachi, Pakistan for six months duration from 12th October 2019 to 11th April 2020. Methodology: One hundred and ten patients of both gender with coronary artery disease were enrolled in this study. Informed consent was taken after explaining the procedure, risks and benefits of the study. In our study, all the included patients were given the emergency treatment and their blood samples were sent to laboratory to assess the outcome variable i.e. glycemic control. All the data was analyzed by SPSS 24.0. Results: Mean ± SD of age was 62.5±8.4 years. Out of 110 patients, 65 (59.1%) were male while 45 (40.9%) were female. Obesity was found in 41 (37.3%) patients. Glycemic control was noted in 20 (18.2%) patients. Conclusion: It is to be concluded that less glycemic control was noted among coronary artery disease (CAD) patients with increasing prevalence of diabetes. Indicators of quality care (HbA1c & other complications) should be assessed regularly for better diabetes management. Keywords: Glycemic Control, Coronary Artery Disease, Type 2 Diabetes, Risk Factors
