Regional distribution of white matter hyperintensity burden in coronary artery disease and links with coronary revascularization procedure

Zacharie Potvin-Jutras, Stefanie A Tremblay, Ali Rezaei, Safa Sanami, Dalia Sabra, Brittany Intzandt, Lindsay Wright, Christine Gagnon, Amélie Mainville-Berthiaume, Olivier Parent, Mahsa Dadar, Josep Iglesies‐Grau, Christopher J. Steele, Mathieu Gayda, Anil Nigam, , Claudine Joëlle Gauthier

This study examines regional white matter hyperintensity (WMH) burden in coronary artery disease (CAD) and finds that CAD is associated with higher WMH volumes, with CABG linked to greater superficial WMH burden than PCI.

Enhanced fitness relates to reduced cerebrovascular reactivity and perfusion in a sample of very healthy older adults

Brittany Intzandt, Dalia Sabra, Catherine Foster, Laurence Desjardins-Crépeau, Rick D. Hoge, Christopher J. Steele, Louis Bherer, Claudine Joëlle Gauthier

The paper examines the relationship between fitness, cerebral blood flow, and cerebrovascular reactivity in older adults, finding that higher fitness is associated with reduced cerebrovascular reactivity and altered hemodynamic responses.
