Key result
Hypokalemia was present in 87% of patients receiving thiazides during acute myocardial infarction and ventricular fibrillation, compared to 2.6% of patients not receiving these medications.

Supports potassium monitoring in thiazide-treated acute MI; leaves open whether repletion reduces VF risk.
Observational (n=59)
Is thiazide use associated with hypokalemia in patients with acute myocardial infarction and ventricular fibrillation?
Absolute Event Rate: 87% vs 2.6%
Thiazide use is strongly associated with hypokalemia in patients presenting with acute myocardial infarction and ventricular fibrillation, highlighting the need for prompt potassium correction to mitigate arrhythmia risk.
M. Duke (1978) conducted an observational in Acute myocardial infarction and ventricular fibrillation (n=59). Thiazide preparation vs. Not receiving thiazides was evaluated on Hypokalemia. Hypokalemia was present in 87% of patients receiving thiazides during acute myocardial infarction and ventricular fibrillation, compared to 2.6% of patients not receiving these medications.
