Prevalence of Hyperkalemia in Myocardial infarction

Abstract

Aim: Increased potassium level in cardiac patient is extremely dangerous. It should be controlled strictly in myocardial infarction patients with precautions. Methods: Total 3340 patients with hyperkalaemia history were collected from Mayo hospital Lahore.Majority of patients are hospital admitted. Mean age 49±5 years, 59% males and 41% females. We assess the incidence and influencing factors on potassiu level in myocardial infarction patients.Patients were classified as : <4 mEg/L, 4 to <4.8 mEg/L, 4.8 to <5.5, 5.5 to <6.0 mEg/L, and >6.0 mEg/L. Linear regression analysis were applied on multivariate variables. The association between the increased risk of hyperkalemic in hospital admitted patients and mortality rate were also assessed. Results: From 3340 patients with hyperkalemia with or without myocardial infarction. The hyperkalemia rate (potassium <4.8 mEg/L) was 19.3% in patients with chronic cardiac diseases. Mild to moderate hyperkalemia potassium rate (potassium 5.5 to <6.0 mEg/L) had in 11.3% of patients. The most high rate of hyperkalemia (potassium > 6.0 mEg/L) in patients was in 23%. There were unreasonable high mortality risk were noted in high rate of hyperkalemia in patients. There is strong relationship with early diagnosed patients and excellent prognosis.Conclusion: Hyperkalemia is very dangerous in cardiac disease patients. Higher levels of potassium in patients are directly coupled with increased mortality rate in hospitals, with increased risks of hyperkalemia adverse outcomes were noted even at mild rate of hyperkalemia. It is concluded that more aggressive and quick treatment of hyperkalemia may improve patient health and prognosis.
