Abstract

Abstract : Objective: In this study we investigated serum phosphorus levels in patients with acute left heart failure. Figure. No caption available. Design and method: A total of 215 participants, 115 patients with acute left heart failure and 100 controls, were enrolled in the study. Patients applied to emergency room with the complaints of heart failure were assessed by echocardiography. Ejection Fraction (EF) levels lower than 50% were accepted as heart failure. Paients with renal disorders, hyperparathyroidism, chronic hearth failure, alcoholism, intake of medications that alter phosphorus level were excluded. Mean phosphorus levels of each group were measured and compared each other. SPSS 12.0 package program (SPSS Inc., Chicago, Illinois) was used for statistical analysis. Chi square test was used to compare categorical measures between the groups. Mann Whitney U or T test was used for comparison of numerical measurements between the two groups. Level of statistical significance was considered as 0.05 in all tests. Results: There were 148 (69%) women and 67 (31%) men in present study. The mean age was 52.6 years. Demographic characteristics of participants were not significantly different between the groups. Mean EF levels of groups were 40.8 versus 60.0 respectively. The difference was statistically significant (P < 0.001). Mean phosphorus levels were 3.01 versus 4.27 mg/dl respectively. There was statistically significant difference (P = 0.041) (Table 1). Table 1: Phosphorus levels in the study and control groups. Conclusions: Phosphorus is a major intracelluler constituent. The deficiency of phosphorus can cause a variety of signs and symptoms. Myocardial creatine phosphate, ATP, and ADP levels reduce in case of phosphate deficiency. In addition to these, mitochondrial and myofibrillar creatine phosphokinase activities also reduces. Alterations occur in mitochondrial oxygen consumption, acid-extractable phospholipid precursors, and mitochondrial oxidation of long chain fatty acids due to phosphate depletion. All these effect heart muscles and can cause heart failure. Consequently phosphorus levels should be controlled in patients with acute left heart failure. Phosporus supplementation may be a supportive treatment.
