| description | Introduction: Acute myocardial infarction (AMI) is one of the
leading causes of mortality and morbidity. Various prognostic
markers have been used in AMI some of which are expensive
and/or not easily available.
Aim: To determine the role of serum uric acid levels in predicting
short-term outcome in AMI.
Materials and Methods: A hospital-based prospective,
analytical observational study, in 102 consecutive AMI patients
(WHO criteria), ≥ 18 years of age, admitted to the Departments
of Medicine and Cardiology. Patients with recurrent myocardial
infarction (MI), with additional confounding factors likely to alter
serum uric acid levels were excluded. Serum uric acid was
measured by using VITROS Uric acid slide method.
Statistical Analysis: Unpaired ‘t’ test was used to study
association of serum uric acid levels with individual parameters.
Unadjusted multivariate logistic regression analysis was used
for comparison of variables against in-hospital mortality. A
‘p-value’ <0.05 was considered statistically significant
Results: There was a male preponderance (Male:Female =
1.83:1.0) with a mean age of 58.09±13.40 years. Chest pain
(73.53%) was the commonest symptom. Anterior-wall was
the commonest site (66.67%) and ST-segment elevation MI
(STEMI) was the commonest type (55.9%) of MI. One-third
(33.3%) of patients had dyslipidemia and over half (57.84%)
were hypertensive. Over one-fourth (27.45%) had elevated
serum uric acid (>7.0 mg/dL); mean serum uric acid levels were
maximum in patients ≥80 years (7.38mg/dL). Mean serum uric
acid level was higher in NSTEMI compared to STEMI (5.78mg/
dl vs. 5.59mg/dL; p=0.60). Mean serum uric acid was higher
in higher Killip classes (6.58 and 7.38 mg/dL in classes III, IV
respectively) compared to lower classes (3.80 & 4.58mg/dL in
classes I, II respectively). Higher serum uric acid levels were
associated with longer hospital stay (6 days for serum uric acid
<4 mg/dL vs 9 days for serum uric acid >7 mg/dL). Overall
in-hospital mortality was 9.8%; of which the highest number
(70%) had serum uric acid level >7mg/dL (p=0.03).
Conclusion: In AMI, patients with a higher Killip class,
signifying severe disease, were found to have a higher serum
uric acid level. Further, patients with higher serum uric acid
had longer hospital stay and significantly higher in-hospital
mortality. Serum uric acid may be used as a cheap and effective
prognostic indicator in AMI. |
