Progenitor Cell Function and Cardiovascular Remodelling Induced by SGLT2 Inhibitors.

Sodium-glucose cotransporters 2 (SGLT2) are high-capacity, low-affinity transporters, expressed mainly in the early portion of the proximal renal tube, mediating up to 90% of renal glucose uptake, while SGLT1 receptors are found mainly in the small intestine, facilitating glucose absorption. SGLT2 inhibitors (SGLT2i) originally emerged as agents for the treatment of type 2 diabetes mellitus; however, they soon demonstrated remarkable cardio- and renoprotective actions that led to their licensed use for the treatment of heart failure and chronic kidney disease, regardless of the diabetic status. Cardiovascular remodelling represents an umbrella term that encompasses changes that occur in the cardiovascular system, from the molecular and cellular level, to tissue and organs after local injury, chronic stress, or pressure.

Baseline neutrophil-to-lymphocyte ratio and efficacy of SGLT2 inhibition with empagliflozin on cardiac remodelling.

Aims: The neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation and plays a critical role in the assessment and prognosis in patients with heart failure. The EMPA-HEART CardioLink-6 trial demonstrated that patients with type 2 diabetes (T2D) and coronary artery disease (CAD) treated with a sodium-glucose transport protein 2 inhibitor for 6 months experienced regression in left ventricular mass. Given this, we evaluated the relationship of baseline NLR and cardiac reverse remodelling in the entire cohort of this trial.

Health-related quality of life after restrictive versus liberal RBC transfusion for cardiac surgery: Sub-study from a randomized clinical trial.

Background: Transfusion Requirements in Cardiac Surgery III (TRICS III), a multi-center randomized controlled trial, demonstrated clinical non-inferiority for restrictive versus liberal RBC transfusion for patients undergoing cardiac surgery. However, it is uncertain if transfusion strategy affects long-term health-related quality of life (HRQOL).

Study Design And Methods: In this planned sub-study of Australian patients in TRICS III, we sought to determine the non-inferiority of restrictive versus liberal transfusion strategy on long-term HRQOL and to describe clinical outcomes 24 months postoperatively.

Upregulation of Krebs cycle and anaerobic glycolysis activity early after onset of liver ischemia.

The liver is a highly vascularized organ receiving a dual input of oxygenated blood from the hepatic artery and portal vein. The impact of decreased blood flow on glucose metabolism and how hepatocytes could adapt to this restrictive environment are still unclear. Using the left portal vein ligation (LPVL) rat model, we found that cellular injury was delayed after the onset of liver ischemia.

Management of postoperative atrial fibrillation after cardiac surgery.

Purpose Of Review: Postoperative atrial fibrillation (POAF) occurs commonly after cardiac surgery and is associated with a number of adverse outcomes. This article will review the available evidence on the prevention and treatment of atrial fibrillation after cardiac surgery. Using this knowledge, we propose a conceptual framework on the management of patients with POAF during various phases after cardiac surgery.
