    Five-year outcomes after coronary artery bypass grafting and percutaneous coronary intervention in octogenarians with complex coronary artery disease

    We assessed the clinical effectiveness of coronary artery bypass grafting (CABG) in comparison with that of percutaneous coronary intervention (PCI) in octogenarians with triple-vessel disease (TVD) or left ma...

    Cerebral blood flow and metabolism associated with cerebral microbleeds in small vessel disease

    Cerebral microbleeds (CMBs), probably reflecting microangiopathy, have not yet sufficiently been examined in association with cerebral blood flow (CBF) and metabolism. We investigated the relationships between...
