The evidence for sodium-glucose cotransporter 2 inhibitors
(SGLT2i)
in the treatment of type 2 diabetes or chronic heart failure was sufficient
but lacking in acute coronary syndrome (ACS). Our aim was to investigate
the effects of SGLT2i on cardiovascular outcomes in ACS patients.
Studies of SGLT2i selection in ACS patients were searched and pooled.
Outcomes included all-cause death, adverse cardiovascular events,
cardiac remodeling as measured by the left ventricular end-diastolic
dimension (LVEDD) and left ventricular end-systolic dimension (LVESD),
cardiac function as assessed by the left ventricular ejection fraction
(LVEF) and NT-proBNP, and glycemic control. Twenty-four studies with
12,413 patients were identified. Compared to the group without SGLT2i,
SGLT2i showed benefits in reducing all-cause death (OR 0.72, 95% CI
[0.61, 0.85]), major adverse cardiovascular events (MACE) (OR 0.44,
95% CI [0.30, 0.64]), cardiovascular death (OR 0.66, 95% CI [0.54,
0.81]), heart failure (OR 0.52, 95% CI [0.44, 0.62]), myocardial infarction
(OR 0.68, 95% CI [0.56, 0.83]), angina pectoris (OR 0.37, 95% CI [0.17,
0.78]), and stroke (OR 0.48, 95% CI [0.24, 0.96]). Results favored
SGLT2i for LVEDD (MD −2.03, 95% CI [−3.29, −0.77]),
LVEF (MD 3.22, 95% CI [1.71, 4.72]), and NT-proBNP (MD −171.53,
95% CI [−260.98, −82.08]). Thus, SGLT2i treatment reduces
the risk of all-cause death and MACE and improves cardiac remodeling
and function in ACS patients.
