The expanded use of SGLT2 inhibitors motivates us to assess the role of SGLT2 inhibitors in perioperative period on patients who will undergo cardiac surgery in Assiut University.

With over 50 million cases of heart failure worldwide, heart failure is one of the most serious health issues facing humanity. Heart failure patients still have an extremely poor prognosis and quality of life, even with advancements in heart failure treatment. It continues to be the most common cause of hospitalization in elderly.

A substantial number of theories have been proposed to explain the beneficial effects of SGLT2 inhibitors. These include blood pressure lowering, increasing diuresis/natriuresis, improving cardiac energy metabolism, preventing inflammation, weight loss, improving glucose control, inhibiting the sympathetic nervous system, preventing adverse cardiac remodeling, preventing ischemia/reperfusion injury, inhibiting the cardiac Na/H exchanger inhibiting SGLT1, reducing hyperuricemia, increasing autophagy and lysosomal degradation, decreasing epicardial fat mass, increasing erythropoietin (EPO) levels, increasing circulating provascular progenitor cells, decreasing oxidative stress; and improving vascular function.

In addition to lowering blood sugar, several large trials also have demonstrated cardiovascular and renal benefits in patients with T2DM. Surprisingly, recent data also suggest that SGLT-2 inhibitors may improve cardiovascular and renal outcomes in patients without diabetes, leading to expanded indications for their use.
