Objective: To determine the effect of serum potassium levels on short term mortality outcomes in patients with acute myocardial infarction. Methods: This Descriptive Case Series was conducted in the CCU of Mayo Hospital Lahore from 15th November, 2017 to 15th May, 2018. A total of 156 patients of either sex between the age group of 30-60 years and diagnosed as cases of myocardial infarction with symptoms of less than 24 hours duration and serum potassium level of <3.5 mEq/L were included in the study. Patients were then followed up for 7 days and adverse outcome was recorded. Data was analyzed using computer software SPSS Version 22.0. Results: Out of the 156 patients, 119 (76.3%) were males and 37 (23.7%) were females. Mean age of the patients was 47.88±6.24 years, mean weight 85.31±13.14 Kg, mean duration of presenting complaints was 10.269±4.51 hours and mean Serum Potassium levels were 3.05±0.25 mEq/L. Adverse outcome in the form of mortality due to arrhythmias was seen in 15 (9.6%) patients. Conclusion: Low serum potassium level (<3.5mEq/L/L) was significantly associated with increased adverse outcome in acute myocardial infarction patients.

Background The evidence of current epidemiological studies investigating the association between serum potassium levels and mortality of acute myocardial infarction (AMI) patients is controversial and inadequate. Design Systematic review and meta-analysis. Methods Two researchers independently searched the PubMed, EMBASE and Web of Science databases to identify observational studies published prior to 31 October 2017. Similarly, two researchers separately extracted data and any differences were resolved by discussion. Pooled relative risks and 95% confidence intervals (CIs) were computed with an inverse variance-weighted random-effects model. Heterogeneity among studies was assessed with the I2 statistic. Results Seven cohort studies were included for analysis. Compared with the reference group (3.5 to <4.0 mEq/L), the pooled relative risks of mortality were 1.15 (95% CI = 1.00–1.32), 1.09 (95% CI = 0.97–1.24), 1.42 (95% CI = 1.19–1.70) and 1.85 (95% CI = 1.39–2.47) for AMI patients with a potassium level of<3.5, 4.0 to <4.5, 4.5 to <5.0, and ≥5.0 mEq/L, respectively. For admission and post-admission potassium, although J-shaped associations were also indicated, non-significant results were observed for AMI patients with potassium levels of <3.5 mEq/L when compared with the reference group. Notably, in subgroup analyses of study characteristics, stratified by study quality, geographic location, type of outcome, number of cases, type of AMI, and adjustment for potential confounders, the findings were broadly consistent across strata. Conclusions These findings indicate that both lower (<3.5 mEq/L) and higher (≥4.5 mEq/L) serum potassium levels are associated with an increased risk of mortality of patients with AMI.
