Abstract
Background: Physiologic determinants, such as pulse pressure [difference between systolic blood pressure (SBP) and diastolic BP (DBP)], mean arterial pressure (2/3 DBP + 1/3 SBP), and double product [beats per minute (bpm) × SBP], are linked to cardiovascular outcomes. The effects of canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, on pulse pressure, mean arterial pressure, and double product were assessed in patients with type 2 diabetes mellitus (T2DM). Methods: This post hoc analysis was based on pooled data from four 26-week, randomized, double-blind, placebo-controlled studies evaluating canagliflozin in patients with T2DM (N = 2313) and a 6-week, randomized, double-blind, placebo-controlled, ambulatory BP monitoring (ABPM) study evaluating canagliflozin in patients with T2DM and hypertension (N = 169). Changes from baseline in SBP, DBP, pulse pressure, mean arterial pressure, and double product were assessed using seated BP measurements (pooled studies) or averaged 24-h BP assessments (ABPM study). Safety was assessed based on adverse event reports. Results: In the pooled studies, canagliflozin 100 and 300 mg reduced SBP (−4.3 and −5.0 vs −0.3 mmHg) and DBP (−2.5 and −2.4 vs −0.6 mmHg) versus placebo at week 26. Reductions in pulse pressure (−1.8 and −2.6 vs 0.2 mmHg), mean arterial pressure (−3.1 and −3.3 vs −0.5 mmHg), and double product (−381 and −416 vs −30 bpm × mmHg) were also seen with canagliflozin 100 and 300 mg versus placebo. In the ABPM study, canagliflozin 100 and 300 mg reduced mean 24-h SBP (−4.5 and −6.2 vs −1.2 mmHg) and DBP (−2.2 and −3.2 vs −0.3 mmHg) versus placebo at week 6. Canagliflozin 300 mg provided reductions in pulse pressure (−3.3 vs −0.8 mmHg) and mean arterial pressure (−4.2 vs −0.6 mmHg) compared with placebo, while canagliflozin 100 mg had more modest effects on these parameters. Canagliflozin was generally well tolerated in both study populations. Conclusions: Canagliflozin improved all three cardiovascular physiologic markers, consistent with the hypothesis that canagliflozin may have beneficial effects on some cardiovascular outcomes in patients with T2DM.
