Prevalence of Short-Term Mortality and Assessment of Risk Factors of Unstable Angina and Non-ST-Elevation MI in Patients Admitted at CCU of PMCH Nawabshah

Abstract

Objective: To determine the short term mortality and risk factors in patients with
unstable Angina and non-ST elevation Myocardial Infarction at Cardiology
department PUMHS Nawabshah (SBA).
Method: A cross sectional study was conducted at cardiology department PUMHS
Nawabshah from June 2023 to Dec 2023. Acute coronary syndrome patients with
unstable angina and non ST elevation myocardial infarction, either age and gender
were included. Detailed clinical history along with thorough clinical examination was
done. Socio demographic details, mortality and risk factors were noted by researcher
through predesigned Performa. Findings of ECG, laboratory investigations like the
presence of troponin, serum cardiac biomarkers were collected .Data was entered and
analyzed by SPSS version 25, association was confirmed with chi square test at 95%
confidence interval.
Results: - The study results shows that 3.3% patients having the age group 15-25
years,13.3% patients between 26-40 years,36.6% patients between 41-55,46.6%
patients came at the age of 56-80 years. Males were 70% and females were 30%. The
current study reveals the risk factors associated with UA/NSTEMI were as
hypertension in 46% patients, 41% were smokers, and DM was noted in 46.3%.
Hyperlipidemia 49%, positive family history 24.7%, past history of coronary artery
disease in 20%, and renal insufficiency was found in 1% of patients. The complication
rate was 41.5%, 29.6% patients developed left ventricular failure and Arrhythmia in
3.3% patients. Renal dysfunction was seen in 1% and 7.6% patients were expired.
Conclusion: Left ventricular failure was found highly prevalent and the mortality
rate was observed 7.6%. DM, old Age, hypertension, smoking and dyslipidemia
were recorded as the most common risk factors.
