Relationship Between Cardiopulmonary Exercise Testing and Ca-P in Chronic Kidney Disease (CKD)

Evaluation of the Relationship Between Cardiopulmonary Exercise Testing (CPET ) Abnormalities and Ca-P Status in CKD Stage3-5

Reductions in exercise capacity associated with exercise intolerance augment cardiovascular disease risk and predict mortality in chronic kidney disease. This study utilized cardiopulmonary exercise testing to (a) investigate mechanisms of exercise intolerance; (b) unmask subclinical ca and p and vitamin D abnormalities that may precede cardiovascular disease in chronic kidney disease.

Cardiopulmonary exercise testing will carry out in Stage 3-5 chronic kidney disease patients ; estimated glomerular filtration rate <60 ml/min/1.73 m2) and biochemistry will be added (Ca P Via D PTH FGF23).

Inclusion Criteria:
