Cardiovascular Disorders and Risk Factors in Childhood Cranial and Craniospinal Tumors Survivors

Echocardiography - standart protocol. Pulse wave characteristics were obtained using finger photopletysmography (PPG) (Angioscan-01, AngioScan-Electronics) from an infrared light sensor. Endothelial function was also evaluated using occlusion index and shear rate during post-occlusive reactive hyperemia (PORH). CPET was conducted on a treadmill (Intertrack 8100, Schiller, Switzerland) with a breath-by-breath algorithm of gas exchange analysis (Cardiovit CS-200 Ergo-Spiro, Schiller, Switzerland), using Bruce, modified Bruce or Naughton protocols depending on the level of physical tolerance.
