Objective: To determine the frequency of fragmented QRS complex in patients with acute non-ST elevation myocardial infarction (NSTEMI). Study Design: Cross-Sectional Study. Setting: Department of Cardiology, Faisalabad Institute of Cardiology, Faisalabad. Period: July 15, 2019 to January 15, 2020. Material & Methods: One hundred and forty five diagnosed patients of NSTEMI on the basis of chest pain and positive troponin-I were included in this study. The electrocardiography (ECG) was performed to document the presence or absence of f QRS complex in these patients. A 12-lead ECG with paper speed of 25 or 50 mm per second and a voltage of 10 mm/mv was used. FQRS was labeled (as per operational definition). The collected data were entered and analyzed statistically by using SPSS v25.0. Data were stratified for age, gender, diabetes, smoking and hypertension. Post-stratification, f QRS complex was compared by Chi-Square test in stratified groups. A p-value ≤0.05 was taken as significant. Results: Total 145 patients presenting with NSTEMI were selected for this study. Mean age of the patients was 48.2±12.3 year. Among these patients, 90(62.1%) were males, while 55(37.9%) were females. Overall frequency of fQRS complex in patients with NSTEMI was 64(44.1%). Conclusion: There is an association of fQRS among patients with acute non-ST elevation myocardial infarction (NSTEMI). Further prospective studies are needed to determine the clinical significance of fQRS complex and identify its correlation with the incidence of possible complications. [ABSTRACT FROM AUTHOR]

Objective: To determine the correlation between mean RDW values and mean SYNTAX scores in patients of non ST elevation myocardial infarction. Methodology: This descriptive study was conducted at adult Angiography Department of Faisalabad Institute of Cardiology, Faisalabad from September, 2018 to October, 2018. A total of 130 patients were enrolled in this study. Patients were divided into high (n=89) and low (n=41) SYNTAX groups. The high SYNTAX group was defined as patients with value in the third tertile (SYNTAX score, SX score ≥ 33) while the group with low SNTAX score was defined as patients with values in the lower 2 tertiles (SYNTAX score, SX score < 33). The high RDW group was defined as patients with RDW value > 16% and the low RDW group as those with RDW value < 16%. Results: The mean RDW value was correlated with mean SYNTAX score in both groups. The RDW levels were significantly high in patients with high SNTAX score than those with low SYNTAX score (16.2± 1.8 vs. 14.2 ± 1.2, p <0.001). Pearson's coefficient was used to determine the correlation between RDW levels and SYNTAX scores. There was a significant positive correlation between mean RDW value and mean SYNTAX score value (r=0.831, p <0.001). Conclusion: We found a positive and significant correlation between mean RDW values and mean SYNTAX scores in patients of non-ST elevation myocardial infarction. This reflects the utility of RDW being a non-invasive and readily available laboratory test to determine the severity and complexity of coronary disease in these patients. [ABSTRACT FROM AUTHOR]
