- The purpose of this study is to determine the level of inhibition of platelet activation of an approved thienopyridine(clopidogrel or prasugrel) and aspirin regimen in the setting of drug eluting coronary stent implantation.
- In subjects with high residual levels of platelet reactivity after receiving either a maintenance or loading dose of either clopidogrel or prasugrel, a cross over of thienopyridine treatment to the alternate medication will occur.
- The study tests the hypothesis that adequate platelet inhibition will occur in subjects who have high levels of platelet reactivity and are subsequently switched from clopidogrel to prasugrel(loading or maintenance dose) without increased episodes of bleeding or MACE events at discharge and 30 days post Percutaneous Coronary Intervention (PCI).

As with coronary artery stenting, activation and embolisation of platelets occurs with carotid artery stenting (CAS). Based on promising data on the use of clopidogrel plus aspirin in coro...

A prospective, randomized trial to compare the time taken to achieve a therapeutic INR upon re-starting warfarin at a "loading" dose (namely 1.5 times the "maintenance" dose for 3 days) co...
The risk of thrombotic complications after implantation of drug-eluting stents (DES) may be increased in patients with diabetes mellitus (DM) or metabolic syndrome (MS). It is recommended ...
Primary percutaneous coronary intervention (PCI) is the main reperfusion therapy in patients with ST-elevation myocardial infarction (STEMI). The optimal platelet inhibition at the time of...
Purpose To retrospectively validate a first-pass analysis (FPA) technique that combines computed tomographic (CT) angiography and dynamic CT perfusion measurement into one low-dose examination. Materi...
To determine the value of ultra-low dose chest CT with tin filtration for ordinal coronary artery calcium (CAC) risk scoring.
To assess sex-specific differences regarding use of conventional risks and coronary artery calcification (CAC) to detect coronary artery disease (CAD) using coronary CT angiography (CCTA).
High-dose aspirin (HDA) is used with intravenous immunoglobulin (IVIg) in Kawasaki Disease (KD). Practice regarding HDA varies, and it is unclear whether HDA duration affects long-term course.
Cardiovascular disease (CVD) is the major cause of mortality worldwide. Coronary artery disease (CAD) contributes to half of mortalities caused by CVD. The mainstay of management of CAD is medical the...
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
A treatment schedule in which the total dose of radiation is divided into large doses.
The highest dose of a biologically active agent given during a chronic study that will not reduce longevity from effects other than carcinogenicity. (from Lewis Dictionary of Toxicology, 1st ed)

A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
