The effects of coronary heart disease, beta-blockade medications and stage duration on graded exercise testing
Controversy exists regarding the effects of beta-blocker medications on functional capacity in cardiac patients and in the effects of disease-related impairments on cardiorespiratory dynamics during exercise testing. Therefore, this study was conducted to examine the exercise responses of 26 …

Reproducibility and sensitivity of Doppler echocardiographic indices of left ventricular function during exercise
… under a placebo (control) condition, acute beta-blockade, and oral hyperhydration states. Hematocrit was measured as a means to assess blood volume changes. The subjects exercised at levels requiring 20, 40 and 60% of their maximum oxygen consumption. Each stage lasted six minutes. PkA, pkV, …

Correlation of Homocysteine Concentration with Plasma Fibrinogen and Physical Activity in Males with Coronary Artery Disease
… Univariate analyses revealed those subjects on beta-blocker therapy (n = 12) had lower fibrinogen concentrations than those not on these medications (n = 28) (277.7 ± 16.7 vs. 316.1 ± 10.9 mg/dl , respectively, p = 0.04). A trend existed for those on beta-blockade to also have lower Hcy …

Myocardial ischemia-reperfusion and cardioprotection. A study with microdialysis in a porcine model.
… years, concerns with the use of perioperative beta-blockers have been debated. Beta-blockers may inhibit the pharmacological preconditioning elicited by volatile anaesthetics. In the third study, it was demonstrated that levosimendan, in the presence of beta-blockade, was still able to induce a …
