Prevalence, Determinants and Clinical Significance of Cardiac Troponin-I Elevation among Individuals with Hypertensive Emergency: A Prospective Observational Study

INTRODUCTION: Cardiac troponin-I (cTnI) elevation release during hypertensive emergencies (HEs) is a frequent epiphenomenon that may tangle management of individuals being treated for HEs. The primary objective of this study was to determine the prevalence, determinants, and clinical significance of cTnI elevation and secondary objective was to find out the prognostic significance of cTnI elevation in patients admitted for HE in the emergency department (ED) of a tertiary care hospital. METHODOLOGY: The investigator has employed the quantitative research approach with a prospective observational descriptive design. The population of this study comprised of 205 adults, which included both males and females, who were more than or 18 years of age. The subjects were selected by non-probability purposive sampling technique. The study was conducted from August 2015 to December 2016 (16 months). Ethical permission was obtained from the Institutional Ethics Committee (IEC), Max Super Speciality Hospital, Saket, New Delhi and well-informed written consents were taken from the subjects. The analysis of data was done with the help of SPSS, version 17.0. RESULTS: Out of 205 patients in the study, cTnI elevation was found in 102 patients (49.8%). Moreover, there was increased duration of stay in the hospital in patient with elevated cTnI level with mean duration stay 1.55 ± 0.82 (p <0.001). In addition, cTnI elevation was associated with increased mortality, 11 out of 102 in an elevated cTnI group (10.8%) with p <0.002. CONCLUSION: It was found that cTnI elevation in individuals affected by various clinical factors. The authors highlighted a high frequency of mortality among the individuals presented with HE with elevated cTnI level, whereas the presence of cTnI was associated with greater odds of death.
