Association of high BNP level with heart failure in patients presenting with STEMI.
Objective: The objective of this study is to to determine the association of high BNP level with heart failure in patients presenting with STEMI. Study Design: Cohort Study. Setting: Department of Cardiology, Punjab Institute of Cardiology, Lahore. Period: 01 January 2017 to 30 June 2017. Material & Methods: After meeting the inclusion criteria 150 patients were enrolled. Informed consent and demographic information was taken. Then patients divided in two groups, high and normal BNP groups. Then patients were admitted in cardiology wards and were followed-up there for 5 days. Patients evaluated for symptoms of heart failure and underwent echocardiography for confirmation of presence or absence of heart failure. All the collected data was entered and analyzed on SPSS version 21. Results: In this study the mean age high BNP group was 48.87± 10.18 years while the mean age in normal BNP group was 48.99±12.15 years. Male to female ratio of the patients was 2:1. The heart failure occurred in 19(12.67%) patients. There is 1.58 times higher risk of heart failure in high BNP than normal BNP i.e. RR=1.58[1.14-2.19]. Conclusion: This present study concluded that high BNP level is strongly associated with heart failure in patients presenting with STEMI.
