Role of multidetector computed tomography in the diagnosis and management of patients attending the rapid access chest pain clinic, The Scottish computed tomography of the heart (SCOT-HEART) trial: study protocol for randomized controlled trial.

Background: Rapid access chest pain clinics have facilitated the early diagnosis and treatment of patients with coronary heart disease and angina. Despite this important service provision, coronary heart disease continues to be under-diagnosed and many patients are left untreated and at risk. Recent advances in imaging technology have now led to the widespread use of noninvasive computed tomography, which can be used to measure coronary artery calcium scores and perform coronary angiography in one examination.

Effect of enoxaparin versus unfractionated heparin in diabetic patients with ST-elevation myocardial infarction in the Enoxaparin and Thrombolysis Reperfusion for Acute Myocardial Infarction Treatment-Thrombolysis In Myocardial Infarction study 25 (ExTRACT-TIMI 25) trial.

Background: Patients with diabetes mellitus (DM) are at higher risk for complications after ST-elevation myocardial infarction (STEMI) than patients without DM. Potent antithrombotic therapies may offer particular benefit for these high-risk patients and must be balanced against the potential for increased bleeding.

Methods: We performed a prospectively planned analysis of efficacy and safety in patients with DM among 20,479 patients with STEMI treated with fibrinolysis and randomized to a strategy of enoxaparin (up to 8 days) or unfractionated heparin (UFH) (48 hours) in ExTRACT-TIMI 25.

Enoxaparin vs. unfractionated heparin with fibrinolysis for ST-elevation myocardial infarction in elderly and younger patients: results from ExTRACT-TIMI 25.

Aims: To determine the effects of age on outcomes in patients with STEMI treated with a strategy of enoxaparin (ENOX) vs. unfractionated heparin (UFH).

Methods And Results: In the ExTRACT-TIMI 25 trial, 20,479 patients with STEMI were randomized in a double-blind fashion to UFH or ENOX.
