Frailty is a geriatric syndrome of impaired resistance to stressors due to a decline in
physiologic reserve. Frailty and cardiovascular disease (CVD) share a common biological …

Objectives: The purpose of this study was to test the value of gait speed, a clinical marker for
frailty, to improve the prediction of mortality and major morbidity in elderly patients …

Frailty is a state of late life decline and vulnerability, typified by physical weakness and
decreased physiologic reserve. The epidemiology and pathophysiology of frailty share …

BACKGROUND: Acute kidney injury (AKI) requiring renal replacement therapy (RRT) in
patients undergoing cardiac surgery is associated strongly with adverse patient outcomes …

BACKGROUND: Transaortic valve implantation has recently been introduced as an

Background—In the era of increasing percutaneous treatment options for heart disease, the
estimation of surgical risk has become a key factor in selecting optimal treatment strategies …

Risk assessment models developed from administrative and clinical databases are used for
clinical decision making. Since these models are derived from a database, they have an …

Background—Although echocardiography is commonly performed before coronary artery
bypass surgery, there has yet to be a study examining the incremental prognostic value of a …

Background—The age cutoff to define elderly is controversial in cardiac surgery, empirically
ranging from≥ 65 to≥ 80 years. Beyond semantics, this has important implications as a …

Predicting outcomes in open-heart surgery can be challenging. Unexpected readmissions,
long hospital stays, and mortality have economic implications. In this study, we investigated …
