ABSTRACT
Aim: The purpose of this study was to predict
the patient’s death due to sudden cardiac arrest with left ventricular
dysfunction by analyzing the value of BNP
Study design: Prospective
longitudinal study
Place and duration: This study was conducted at Karachi institute of
heart diseases Karachi, Pakistan from Feb 2020 to Feb 2021
Methodology: This cross sectional study was
conducted from Feb 2020 to Feb 2021 on 70 patients who were pin pointed with
acute STEMI complicated by left ventricular systolic failure and hospitalized in our hospital. A total of 70 patients who
were recognized with STEMI, 48 of whom got primary PCI, and 17 of whom received
thrombolytic treatment.
Results: The average age of the patients was
57.6 years and the range being from 35 to 80 years. Male patients constituted
73.3 percent of the study. It was discovered a mean of NYHA of 2.5, an average
Killip classification of 2.8 and an average TIMI score of 8.1. A 90-day
follow-up showed that 48 patients survived out of which 7 were reported to have
a life-threatening arrhythmia and 12 had sickle cell disease. When ROC curve was shown, Pro-BNP indicated Sc.D. and unanticipated
cardiac death was forecasted which also stipulated an AUC of 0.76, while the AUC was 69.6
percent of the ROC curve of the same neuropeptide in evaluating accuracy in
prediction of VT, by. A Kaplan-Meier analysis reveals that an increase in
pro-BNP over 3.2ng/ml has a significant predictive influence on SCD [OR 0.748
(CI 95 percent: 0.07-0.932), p-value .039]
Conclusion: BNP levels in individuals with ischemic
cardiomyopathy after an acute MI are a significant, independent predictor of
sudden death.
