An analytical Study to Evaluate the correlation between Serum Uric Acid Levels and Deaths in Acute Myocardial Infarction Patients At a Tertiary Level Institute Catering to Rural Population of Western Maharashtra

Abstract

Introduction: Cardiovascular diseases are the number one cause of mortality all over the world. Elevated serum uric acid is highly predictive of mortality in patients with heart failure or coronary artery disease. We conducted this study to assess serum uric acid levels on admission as a potential predictor of short-term mortality (7 days) in acute myocardial infarction patients. Methodology: Total of 200 patients diagnosed with the myocardial infarction (MI) in our hospital along with 200 age and gender matched controls were selected for this study. The clinical history, examination, ECG changes and biochemical markers were evaluated on day 0, 3 and 7. Association with Killips class and mortality in STEMI / NSTEMI cases was done. Results: The study had 200 cases and 200 controls. The mean age of cases was 62.54 ± 18.24 years and controls was 61.94±17.25 years. There were majority males among both cases 114 (57%) and controls 112 (56%). The patients were classified using Killip’s class. Majority belong to class I 98 (49%) followed by II 42 (21%). There were 26 (13%) of class III and 34 (17%) into class IV. There is significant difference seen between uric acid levels of cases and control on day 1, 3 and 7 (p<0.001). There was 25% mortality (50 deaths) seen among the cases. There was association seen between Killips class III & IV and mortality, there was higher mortality seen in STEMI as compared to NSTEMI (i.e. p<0.05). Conclusion: Our study concludes that the serum uric acid (SUA) levels have significant association with Killip‘s class and mortality in Acute Myocardial Infarction cases.
