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.
Observational (n=59)
Is thiazide use associated with hypokalemia in patients with acute myocardial infarction and ventricular fibrillation?
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.
Absolute Event Rate: 87% vs 2.6%
Ten of 59 patients (17%) were receiving a thiazide preparation at the time of an acute myocardial infarction and ventricular fibrillation. Hypokalemia was present in seven of eight patients (87%) receiving thiazides, whereas it was observed in only one of 38 patients (2.6%) not receiving these medications. If hypokalemia is present in patients receiving thiazides who have had an acute myocardial infarction, it should be corrected so as to remove this predisposing cause of ventricular fibrillation.
M. Duke (Mon,) conducted a 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.
