Brief summary
Sodium glucose co-transporter 2 inhibitors (SGLT2i) proved their favorable outcomes in heart failure. However, it is still unknown if their role extent into preventing heart failure, especially after acute myocardial infarction. This study aimed at identifying if there is such role for SGLT2i.
Detailed description
A notable breakthrough in the management of heart failure is the use of a class of anti-diabetic medications known as, gliflozins. Gliflozins act by inhibiting the sodium glucose co-transporter 2 (SGLT-2). This is a transmembrane protein found at the luminal border of tubular cells of the proximal convoluted tubules of the kidney. It accounts for around 90% of glucose re-absorption. Inhibiting the SGLT-2 results in better glycemic control in patient with diabetes mellitus type 2 (DMT2). In heart failure, sodium glucose co-transporter 2 inhibitors (SGLT2i - i.e., gliflozins) were found to have a favorable cardiovascular outcome independent of their anti-glycemic effect. In patients with acute myocardial infarction, the heart function as a pump is affected & heart failure develops. In particular, patients with anterior ST-elevation myocardial infarction (STEMI) are at a higher risk of remodeling & heart failure. This is due to the cutoff in blood supply in the left anterior descending (LAD) coronary artery which supplies a great area of left ventricle. A question that rises: is there a role for SGLT2i, & in particular dapagliflozin, in acute myocardial infarction in improving post-infarction cardiac function & preventing heart failure? especially in patients who experience Anterior ST-Elevation Myocardial Infarction (STEMI).
