From: Acute vitamin C improves cardiac function, not exercise capacity, in adults with type 2 diabetes
The effect of acute, peak exercise on systolic and diastolic function saline and during an acute vitamin C infusion. Data in panels a–d are presented as the change (Δ) from rest/pre-infusion to peak exercise. a Change in lateral E:E’. b Change in septal E:E’. c Change in mitral valve deceleration time. d Change in ejection fraction from rest/pre-infusion to peak exercise. e Left ventricular circumferential strain measured at peak exercise. f Left ventricular longitudinal strain measured at peak exercise. *Significantly different from saline (P < 0.01). †Significant interaction between the vitamin C intervention and group (P = 0.018); mitral valve deceleration time decreased in participants with T2D with vitamin C. There was a suggestive change in ejection fraction with acute, peak exercise during vitamin C infusion (P = 0.057). There was a suggestive decrease in the peak exercise circumferential strain with during vitamin C infusion (P = 0.052)
