- AIMS/HYPOTHESIS: SGLT2 inhibition is associated with a reduced risk of cardiac disease that is still largely unexplained. According to one hypothesis, improved myocardial energetics may explain the cardioprotective effects of SGLT2i. However, recent mechanistic studies that have addressed this question have lacked the power to detect discrete but still clinically significant effects.METHODS: We pooled data from two recent randomized clinical trials and performed a meta-analysis to determine the effect of SGLT2 inhibition on myocardial oxygen consumption and myocardial external efficiency measured by positron emission tomography.RESULTS: SGLT2 inhibition reduced myocardial oxygen consumption (-1.06 [95%CI: 0.22-1.89] mL/100 g/min (n = 59, p = 0.01)), but did not affect myocardial external efficiency (2.22 [95%CI: 0.66-5.11] % (n = 59, p = 0.13)).CONCLUSIONS: /interpretation: SGLT2 inhibition reduces myocardial oxygen consumption at rest, which may contribute to the drugs' cardioprotective effects.

- Abdominal obesity is associated with elevated postprandial triglycerides (TG), an independent risk factor for cardiovascular diseases. Previous studies show that whey protein (WP) and dietary fiber may separately reduce postprandial TG. However, few studies have investigated the long-term effects of WP and dietary fiber on postprandial TG. We aimed to investigate the separate and combined long-term effects of WP and dietary fiber from wheat bran on postprandial TG and markers of lipid metabolism in subjects with abdominal obesity. We conducted a 12-week, double-blind, randomized, controlled, parallel intervention study. In a 2 × 2 factorial design, 73 adults were randomized to receive 60 g/day of either WP hydrolysate or maltodextrin (MD) combined with high-fiber wheat bran products (HiFi; 30 g dietary fiber/day) or low-fiber refined wheat products (LoFi; 10 g dietary fiber/day). A high-fat meal test was conducted before and after the intervention. Sixty-five subjects were included in the final analyses. There were no differences between intervention groups in postprandial TG assessed as incremental area under the curve (iAUC). WP-LoFi had reduced postprandial TG assessed as total area under the curve (tAUC) and reduced fasting TG compared with all other groups, and reduced fasting apolipoprotein B-48 compared with MD-LoFi. There were no changes in lipoprotein lipase activity. Total cholesterol and apolipoprotein B-100 were reduced after WP intake compared with MD. Total cholesterol was increased after HiFi intake compared with LoFi. In conclusion, intake of WP in combination with low-fiber cereal products for 12 weeks had beneficial effects on postprandial TG tAUC and fasting TG, but not on postprandial TG iAUC in subjects with abdominal obesity. Combining WP with high-fiber wheat bran products did not improve lipid profile.
