ABSTRACT
Electrolyte disturbances, specially hypokalemia and hypomagnesaemia are common in patients with congestive heart failure [CHF]. This study was carried out to determine the serum concentration of magnesium [Mg] in patients with CHF. This descriptive analytical study performed at Mashhad Ghaem hospital between shahrivar 1382 and shahrivar 1383. Serum Mg concentration of 60 patients with symptomatic CHF was measured by spectrophotometric absorption technique and analyzed based on clinical variables and echocardiographic parameters of left ventricular function. Data was analyzed in SPSS software by t-test at alpha=0.05. From 60 patients with CHF, 52% were male and 48% were female with mean age 63 +/- 13.15 years. 56.5% of patients were in the range of 60-80 years old. Hypomagnesaemia was showed in 55% of patients. No significant correlation was found between serum Mg level, age, sex, functional class and LVEF. Hypomagnesaemia was common in the presence of arrhythmia, Atrial fibrillation [60%] and PVC [80%] Hypomagnesaemia is common in patients with CHF especially in patient with arrhythmia [AF, PVC]
