Abstract Context: Thyroid hormone regulates several cardiovascular functions, and low T3 levels are frequently associated with cardiovascular diseases. Whether T3 exerts any acute and direct effect on endothelial function in humans is unknown. Objective: Our objective was to clarify whether acute changes in serum T3 concentration affect endothelial function. Design, Setting, and Subjects: Ten healthy subjects (age, 24 ± 1 yr) participated in a double-blind, placebo-controlled trial at a university hospital. Interventions: T3 (or placebo) was infused for 7 h into the brachial artery to raise local T3 to levels observed in moderate hyperthyroidism. Vascular reactivity was tested by intraarterial infusion of vasoactive agents. Main Outcome Measures: We assessed changes in forearm blood flow (FBF) measured by plethysmography. Results: FBF response to the endothelium-dependent vasodilator acetylcholine was enhanced by T3 (P = 0.002 for the interaction between T3 and acetylcholine). The slopes of the dose-response curves were 0.41 ± 0.06 and 0.23 ± 0.04 ml/dl·min/μg in the T3 and placebo study, respectively (P = 0.03). T3 infusion had no effect on the FBF response to sodium nitroprusside. T3 potentiated the vasoconstrictor response to norepinephrine (P = 0.006 for the interaction). Also, the slopes of the dose-response curves were affected by T3 (1.95 ± 0.77 and 3.83 ± 0.35 ml/dl·min/mg in the placebo and T3 study, respectively; P < 0.05). The increase in basal FBF induced by T3 was inhibited by NG-monomethyl-l-arginine. Conclusions: T3 exerts direct and acute effects on the resistance vessels by enhancing endothelial function and norepinephrine-induced vasoconstriction. The data may help clarify the vascular impact of the low T3 syndrome and point to potential therapeutic strategies.

AbstractTo examine the acute influence of pedaling cadence on arterial stiffness in young men, 15 healthy men (21.8±0.4 years) underwent 3 trials in self-control crossover design: non-cycling control (CON), cycling at 60 (RPM60) and 90 rounds per min (RPM90). Cycling lasted 30 min at intensity of 35% heart rate reserve. Arterial stiffness in cardio-ankle vascular index (CAVI) was measured at baseline (BL), immediately after (0 min) and 40 min after cycling. There were no significant CAVI changes over time in CON. CAVI in RPM60 decreased immediately after exercise and returned to baseline afterwards (6.1±0.2, 5.6±0.2 and 6.0±0.2 at BL, 0 and 40 min, respectively). RPM90 elicited significant CAVI reduction from 6.2±0.2 at BL to 5.5±0.2 at 0 min, and reverted to 5.7±0.1 at 40 min, maintaining significant difference to its baseline. There was no significant CAVI difference between RPM60 and CON, whereas CAVI in RPM90 was significantly lower than that in CON at 0 min (5.5±0.2 vs 6.1±0.2, P<0.01) and 40 min (5.7±0.1 vs 6.3±0.1, P<0.05). Despite equivalent exercise volume, arterial stiffness improvement induced by cycling was influenced by pedaling cadence. Higher cadence resulted in superior effect on arterial stiffness.
