title: The Association of Calcium-Phosphorus Product With the Severity of Cardiac Valves Failure in Patients Under Chronic Hemodialysis.
abstract: BACKGROUND
  Recent studies have mainly focused on the roles of serum calcium and phosphorus product in the development of valvular heart failure. We determined the association of calcium-phosphorus product with the severity of heart valve failure in patients under chronic hemodialysis (being under hemodialysis for 6 months or more) in Boo-Ali Hospital in 2012 and 2013.
  
  
  METHODS
  It was a cross-sectional, descriptive, comparative study. Thirty-three patients undergoing chronic hemodialysis were recruited to the study. All the patients were hospitalized at Boo-Ali Hospital. The study was done in a 2 years long time frame and the association of calcium-phosphorus product and severity of heart valve failure was evaluated among them.
  
  
  RESULTS
  The results demonstrated that there was no significant association between age, gender, renal failure cause and hemodialysis duration (P > 0.05). Our results showed a negative correlation between the severity of cardiac valves failure and CA × P level. It was not a meaningful correlation though (P > 0.05).
  
  
  CONCLUSIONS
  Based on the obtained results, it is concluded that there is not any association between calcium-phosphorus product and the severity of heart valve failure in patients under chronic hemodialysis.
