Association of CHADVASC Score in Predicting In-Hospital Mortality in Patients with ST-Segment Elevation Myocardial Infarction Undergoing Primary PCI

Abstract

Objective: To assess CHADVASC score in predicting in-hospital mortality in patients presenting to the hospital with ST
segment Elevation Myocardial Infarction undergoing primary PCI.

Study Design: Analytical Cross-sectional study.

Place and Duration of Study: Armed Forces Institute of Cardiology/National Institute of Heart Diseases, Rawalpindi,
Pakistan, from Mar 2023 to Apr 2023.

Methodology: A total of 198 patients were enrolled. Their CHADVASC scores were recorded and were divided into Group-A (score of 0-1), B (score 2-3) and C (score 4 and above). Sampling was done by using non-probability consecutive sampling. A brief clinical history including duration of symptoms, comorbid, duration of hospital stay and survivability status were
recorded. Chi-square and Independent sample t-test were applied to find the association between In-hospital mortality and
CHADVASC score, duration of hospital stay as well as comorbids. p-value <0.05 was taken as significant

Results: Among study participants, majority were males 133(67.2%). Mean age of patients was 60.86±9.02 years. In-hospital
mortality was noted in 13(6.56%) patients. There was a significant association between CHADVASC score and mortality
(p<0.001). It was also noted that mortality increased with prolonged duration of stay in hospital (p=0.03). Another observation
noted was that males presented at an earlier age (59.45±9.79 years) than females (63.63±6.54 years).
Conclusion: CHADVASC score like the TIMI score and GRACE score can be used to stratify risk in patients presenting with
Acute Coronary Syndrome (ACS). It is a fairly easy to use test at bed side and can help clinicians decide further treatment
strategies and how .............
