Abstract

Background: Hypomagnesemia, hypokalaemia, and hyponatremia are the common serum electrolyte abnormalities seen in chronic congestive heart failure. The present study was conducted to assess serum magnesium levels in chronic heart failure patients.
Materials & Methods: 90 chronic heart failure patients of both genderswere divided into two groups. Group I were patients with normal magnesium levels (>2mEq/L) and group II patients with low magnesium levels (≤ 2 mEq/L).
Results: Out of 90 patients, males were 50 and females were 40. The mean BMI in group I was 25.1 kg/m² and in group II was 27.5 kg/m². The mean SBP was 122.4 mm Hg in group I and 134.6 mm Hg in group II. DBP was 70 mm Hg in group I and 82.4 mm Hg in group II. There were 8 diabetes in group I and 21 in group II. The difference was significant (P< 0.05). The mean LVEF in group I was 35.6% and in group II was 36.7%. The serum potassium was 4.3 mEq/L in group I and 4.1 mEq/L in group II. Serum creatinine was 1.8 mg/dL in group I and 1.2 mg/dL in group II. The difference was significant (P< 0.05).
Conclusion: Chronic heart failure patients had low serum magnesium level. Low serum magnesium levels were predictor of deranged cardiac & biochemical profile seen in chronic heart failure patients
