Key result
Patients with acute myocardial infarction had significantly lower mean serum potassium levels (3.97 mEq/L) compared to healthy controls (4.41 mEq/L), with hypokalemia occurring in 24% of cases.
Why the study?
Do serum potassium levels predict the severity and clinical outcomes (arrhythmias, heart failure, mortality) in patients with Acute Myocardial Infarction?

Do serum potassium levels predict the severity and clinical outcomes (arrhythmias, heart failure, mortality) in patients with Acute Myocardial Infarction?
Hypokalemia is prevalent in patients with acute myocardial infarction and is significantly associated with an increased risk of arrhythmias, highlighting the importance of monitoring and correcting potassium levels.
Lower potassium levels in acute MI warrant monitoring; cross-sectional data leaves open predictive value for arrhythmias or mortality.
Background: An Acute Myocardial Infarction (AMI) is a subset of a spectrum of IHD that includes unstable angina and AMI with or without ST elevation. Ischemic heart disease (IHD) places a massive health burden on humanity. Sodium (Na + ) and potassium (K + ) have played key roles in the development and maintenance of essential cellular functions throughout more than 2 million years of human evolution. However; there is a lack of current, adequately powered studies that define the optimal range of serum potassium levels with respect to mortality and other important clinical outcomes in patients with AMI. Hence; we planned the present study to evaluate serum potassium levels in AMI and assess its prognostic value in the severity and outcome of AMI.

Neki et al. (2017) conducted a cross-sectional in Acute Myocardial Infarction (n=100). Acute Myocardial Infarction vs. Healthy controls was evaluated on Mean serum potassium levels (p=0.003). Patients with acute myocardial infarction had significantly lower mean serum potassium levels (3.97 mEq/L) compared to healthy controls (4.41 mEq/L), with hypokalemia occurring in 24% of cases.
