Background: The present study was conducted for assessing the incidence of hypokalemia among AMI patients. Materials & methods: A total of 50 patients with presence of AMI and 50 healthy controls were enrolled. Complete demographic details of all the patients were obtained. ECG and ECHO findings were recorded in all the patients. Blood samples were obtained from all the patients. All the collected samples were sent to laboratory and serum potassium levels were evaluated using auto-analyser. Comparison of potassium levels was done between AMI patients and controls. Hypokalemia was defined as presence of serum potassium levels less than 3.5 mEq/L. Results: Mean potassium levels among patients of AMI group and control group was 3.9 mEq/L and 4.6 mEq/L respectively. Non-significant results were obtained while comparing the mean potassium levels among patients of AMI group and control group. Overall, hypokalemia was seen in 14 percent of the patients of the AMI group. Conclusion: Hypokalemia is significantly prevalent among AMI patients.
