Insights
Serum sodium and potassium levels significantly decrease in patients with acute myocardial infarction (AMI). These electrolyte changes correlate with AMI severity and patient outcomes, offering prognostic insights.
Area of Science:
- Cardiology
- Clinical Biochemistry
Background:
- Acute myocardial infarction (AMI) is a major global health concern.
- Limited research exists on serum electrolyte changes and their prognostic value in AMI.
- Serum sodium and potassium alterations in AMI require further investigation.
Purpose of the Study:
- To investigate serum electrolyte (sodium and potassium) changes in AMI patients.
- To correlate these electrolyte levels with AMI severity and patient outcomes.
Main Methods:
- A study involving 100 participants, divided into AMI and control groups.
- Serum electrolytes (Na+, K+) analyzed using flame-photometry.
- Comparison of electrolyte levels between study and control groups across demographics.
Main Results:
- Statistically significant decreases in serum sodium and potassium observed in the AMI group compared to controls.
- Higher sodium levels noted in smokers and diabetic AMI patients; lower in hypertensive patients.
- Lower potassium levels observed in diabetic AMI patients; no significant association with smoking or hypertension.
Conclusions:
- Decreased serum sodium in AMI is attributed to hypoxia-induced sarcolemma permeability changes.
- Reduced serum potassium is linked to elevated catecholamine levels during early AMI.
- Electrolyte imbalances provide potential biomarkers for AMI prognosis.
Objectives:
Acute myocardial infarction (AMI) is one of the leading causes of morbidity and mortality across the world. Serum electrolytes changes in AMI have not been studied extensively and there is paucity of information in the literature in this regard. Scanty information is available in the literature about prognostic value of serum electrolytes in ischaemic heart disease. Hence this study was undertaken to study any changes in the serum electrolytes with special reference to serum sodium and potassium in cases of AMI and study the correlation of serum sodium and potassium in the severity and outcome of AMI.
Materials And Methods:
Hundred people were included in study divided equally in study and control groups. Study group comprised confirmed diagnosis of recent onset of AMI. The blood samples of both the groups were analysed for Serum electrolytes (Na+, K+) by flame-photometry (Bio-Lab Diagnostic kit).
Results:
There was statistically significant decrease in sodium and potassium levels in across all age groups & in both sexes of study group compared to control group. Significant high level of sodium was observed in AMI patients who are smokers and AMI patients with Diabetes whereas the level was low in AMI patients with hypertension. Potassium levels were low in AMI patients with Diabetes whereas the change was insignificant in association with smoking and hypertension.
Conclusion:
Decrease in sodium level was due to hypoxia and ischaemia, which increase the permeability of sarcolemma to sodium whereas decrease in potassium level was influenced by the catecholamine levels which are elevated in early acute myocardial infarction.

Sodium Regulation
Sodium ions make up approximately 90% of extracellular cations, with a normal blood plasma concentration of 136–148 mEq/L. A decrease in blood volume and pressure triggers the release of renin from granular cells in the juxtaglomerular complex (JGC), primarily...
