SGLT2 inhibitors not only improve glycaemic control (lowered blood glucose levels) but also reduce the development, severity and hospitalisation rate of those living with chronic heart failure
Intriguingly clinical researchers also noted that the use of these drugs in individuals with chronic heart failure but without a definite diagnosis of diabetes mellitus type 2 also benefitted enormously in terms of the rate of development / severity of chronic heart failure, incidence of hospitalisations and indeed prematurity of death
Much debate remains regarding the mechanisms by which SLGT2 inhibitors benefit those with CHF
At present there is still much detail to discover but top thoughts at the moment include:
Increased glucose excretion, promotes increased osmosis which off-loads fluid from the system i.e. acts as a diuretic
Enhanced glucose excretion lowers blood glucose levels (even in the non-diabetic) reducing activation of the SNS and RAAS resulting in a reduced blood pressure – off-loading the failing left ventricle
SGLT2 inhibitors may improve functionality at cardiomyocyte level aiding economical increases in force generation and therefore EF and cardiac out-put.
