Serum Lactate Mortality Index (post-CPB): Explanation and Clinical Context The Serum Lactate Mortality Index (SLMI) is a prognostic tool used to estimate the risk of postoperative mortality in patients after cardiopulmonary bypass (CPB). It is calculated by multiplying peak serum lactate levels (mmol/L) by the time elapsed since CPB (hours). Elevated lactate levels reflect impaired tissue perfusion and oxygen deliver
STS Adult Cardiac Surgery Risk Score: Explanation and Clinical Context The STS Adult Cardiac Surgery Risk Score provides an evidence-based estimation of perioperative mortality and morbidity in adults undergoing cardiac surgery. It incorporates patient-specific clinical variables such as age, sex, renal function, history of heart failure, previous cardiac surgery, and type of surgical procedure. The score is derived
STS CABG Mortality Risk Score: Explanation and Clinical Context The STS CABG Mortality Risk Score is a validated tool used to estimate the risk of operative mortality for patients undergoing coronary artery bypass grafting (CABG). It incorporates various clinical variables, including patient demographics, comorbidities, and procedural factors, to provide a personalized risk assessment. This score aids clinicians in d
STS Primary Mitral Valve Repair/Replacement Risk Calculator: Explanation and Clinical Context The STS Primary Mitral Valve Repair/Replacement Risk Calculator is a tool developed by The Society of Thoracic Surgeons to estimate the short-term (operative/30-day) risk associated with mitral valve repair or replacement surgeries for patients with primary mitral regurgitation (MR) and degenerative mitral etiology.
