The Effect of Ticagrelor With or Without Atorvastatin on Endothelial Function in Healthy Males

2016-09-22 21:08:21 | BioPortfolio


To test the effect of atorvastatin or placebo in combination with ticagrelor on ACh-induced vasodilatation of the forearm resistance vasculature as assessed by forearm blood flow (FBF) measurement before and 10 min after a 20 min forearm ischemia. The area under the dose-effect curve (AUC) of different ACh doses will be calculated and compared between treatment groups (atorvastatin + ticagrelor vs. placebo + ticagrelor) and different time points (pre-ischemia vs. post-ischemia).

Medical and Biotech [MESH] Definitions

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

A disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ISCHEMIA) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. Prolonged hypoxia-ischemia is associated with ISCHEMIC ATTACK, TRANSIENT; BRAIN INFARCTION; BRAIN EDEMA; COMA; and other conditions.

The chilling of a tissue or organ during decreased BLOOD perfusion or in the absence of blood supply. Cold ischemia time during ORGAN TRANSPLANTATION begins when the organ is cooled with a cold perfusion solution after ORGAN PROCUREMENT surgery, and ends after the tissue reaches physiological temperature during implantation procedures. WARM ISCHEMIA TIME starts then and ends with completion of SURGICAL ANASTOMOSIS.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.
