Prevalence and progression of cardiovascular calcifications in peritoneal dialysis patients: A prospective study

► Cardiovascular calcifications are considered an important prognostic factor. ► Few data are available on cardiovascular calcifications in patients on peritoneal dialysis. ► Prevalence of cardiovascular calcifications increased from 77% to 90% in 3 years. ► Cardiovascular calcifications progressed in over 70% of peritoneal dialysis patients. ► Serum calcium and phosphate levels are not predictors of calcification prevalence and progression. ► Serum phosphate levels are positively associated with left ventricular hypertrophy.
