Brief Summary:
The purpose of this study is to investigate the effects of Dapagliflozin (FORXIGA) 10mg (n=20) and placebo (n=20) on the renal concentration mechanism, mobilization of Na+ from tissue stores, and mobilization of muscle glycogen and fat, in patients heart failure NYHA classes I and II,with or w/o T2DM in a 4-week double-blind, placebo-controlled, randomized study with 2 treatment arms.
Detailed Description:
Sodium-glucose co-transporter-2 (SGLT-2) inhibitors are a new class of oral medications used for T2DM, which lower blood glucose levels by increasing renal sodium (Na+) and glucose excretion. However, their applications seem to go beyond glycemic control. Recent studies have shown that treatment with SGLT-2 inhibitors significantly improves cardiovascular outcome, with unprecedented reductions in cardiovascular mortality and heart failure hospitalizations. The underlying mechanism of this surprising effect is unclear.
Our hypothesis is that increased Na+ and glucose excretion induced by SGLT-2 inhibitors predisposes to water loss, to which the body responds by increasing urea production in an effort to prevent dehydration. Urea is accumulated in the renal medulla, where it provides the alternative osmotic driving force for water reabsorption. However, hepatic urea production is an energy-intense process, for which amino acids from skeletal muscle are the ideal fuel because they provide both the nitrogen and the energy needed for urea generation. Alanine is transported from muscle to the liver, where it serves as a substrate for new pyruvate generation, which can then be used for the urea cycle, glucose production or ketone body generation. In the same time, as increasing amounts of alanine are shuttled to the liver, muscle will deplete its glucose reservoirs and reprioritize fuel utilization in favour of fatty acids.
