Abstract
Aims
EMPAREG OUTCOME study showed a reduction in cardiovascular events in patients treated with the sodium-glucose transporter 2 inhibitor (SGLT2i) empagliflozin, as compared to placebo. Other drugs of the same class are currently been investigated for cardiovascular outcomes. In the meanwhile, a re-analysis of data collected in available studies can add relevant insight.
Methods
A MEDLINE search for SGLT-2 inhibitors (dapagliflozin, empagliflozin, canagliflozin, ipragliflozin, ertugliflozin, luseogliflozin) was performed, collecting all randomized trials up to November 16, 2015. All trials with a duration of treatment ≥12 weeks, enrolling patients with type 2 diabetes, comparing a SGLT2i with placebo or other comparators were included. The principal outcome was the effect of SGLT2i on all-cause and cardiovascular mortality. Secondary endpoints were myocardial infarction and stroke. Mantel–Haenszel odds ratio with 95 % confidence interval (MH-OR) was calculated.
Results
A total of 71 trials were included (31,199 and 16,088 patients in SGLT2i and comparator groups). Treatment with SGLT2i was associated with a significant reduction in all-cause mortality (MH-OR 0.70 [0.59–0.83], p < 0.001), cardiovascular mortality (MH-OR 0.43 [0.36–0.53], p < 0.001), and myocardial infarction (MH-OR 0.77 [0.63–0.94], p < 0.01), but not stroke (MH-OR 1.09 [0.86–1.38], p = 0.50), with no apparent difference across molecules (after excluding cardiovascular outcome trials).
Conclusions
Available data suggest that the beneficial action observed with empagliflozin on all-cause and cardiovascular mortality in EMPAREG OUTCOME study is a class effect. The present meta-analysis showed a significantly reduction in myocardial infarction, with no increased risk of stroke.
