Significance of N-Terminal Pro Brain Natriuretic Peptide as a Diagnostic Tool for Premature Ventricular Contractions in Patients with Preserved Left Ventricular Function"

Abstract

ObjectiveThe study was aimed to evaluate the levels of NT-proBNP in mild, moderate and frequent ventricular ectopic burden in patients with preserved left ventricular function.Material and methodsA case control study was conducted in Islamic International Medical College (IIMC) in collaboration with Armed Forces Institute of Cardiology (AFIC) after approval from ethical review committee (ERC) of Riphah University (Ref #Riphah/IIMC/ERC/17/0230). It comprised of 120 Premature ventricular contractions (PVCs) patients with 40 patients in each group of mild (<10%), moderate (10-20%) and frequent (>20%) PVCs burden. 40 healthy subjects with no PVCs were taken as a control group. NT-proBNP levels were measured in all groups and statistical analysis was done by applying ANOVA and Pearson correlation tests to evaluate its association with PVCs burdenResultsNT-proBNP levels were found to be raised in all PVCs burden of <10%, 10-20% and >20% as compare to control group with p value of 0.039, 0.02 and 0.009 respectively. p value of ≤0.05 was considered significant. Symptomatic and asymptomatic patients show higher NT-proBNP levels as compared to control group with p-value of .002 and .04.Conclusion It is concluded that NT-proBNP levels are raised in patients of PVCs. This finding can be helpful for diagnostic purposes of PVCs.
