Randomized Controlled Trial Multicenter Study Comparative StudyEarly and late benefits of prasugrel in patients with acute coronary syndromes undergoing percutaneous coronary intervention: a TRITON-TIMI 38 (TRial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet InhibitioN with Prasugrel-Thrombolysis In Myocardial Infarction) analysis.
We evaluated the relative contributions of the loading and maintenance doses of prasugrel on events in a TRITON-TIMI 38 (TRial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet InhibitioN with Prasugrel-Thrombolysis In Myocardial Infarction) analysis. ⋯ Both the loading dose and maintenance dose of prasugrel were superior to clopidogrel for the reduction of ischemic events. This result emphasizes the importance of maintaining high levels of inhibition of platelet aggregation via P2Y(12) receptor inhibition, not only for the prevention of periprocedural ischemic events but also during long-term follow-up. The excess major bleeding observed with the use of prasugrel occurred predominantly during the maintenance phase. Approaches to reduce the relative excess of bleeding with prasugrel should focus on the maintenance dose (e.g., reduction in maintenance dose in previously reported high-risk subgroups, such as the elderly and those patients with low body weight).

Randomized Controlled TrialIntensive lipid-lowering with atorvastatin for secondary prevention in patients after coronary artery bypass surgery.
The aim of this post hoc analysis from the TNT (Treating to New Targets) trial is to determine whether patients with previous coronary artery bypass grafting (CABG) surgery achieved clinical benefit from intensive low-density lipoprotein (LDL)-cholesterol lowering. ⋯ Intensive LDL-cholesterol lowering to a mean of 79 mg/dl with atorvastatin 80 mg/day in patients with previous CABG reduces major cardiovascular events by 27% and the need for repeat coronary revascularization by 30%, compared with less intensive cholesterol-lowering to a mean of 101 mg/dl with atorvastatin 10 mg/day.

Comparative StudyPlasma N-terminal B-Type natriuretic peptide as an indicator of long-term survival after acute myocardial infarction: comparison with plasma midregional pro-atrial natriuretic peptide: the LAMP (Leicester Acute Myocardial Infarction Peptide) study.
Our aim was to assess the prognostic value of midregional pro-atrial natriuretic peptide (MR-proANP) in patients after acute myocardial infarction (AMI). ⋯ The A- and B-type natriuretic systems are activated after AMI. Midregional pro-atrial natriuretic peptide is a powerful predictor of adverse outcome, especially in those with an elevated NT-proBNP. Midregional pro-atrial natriuretic peptide may represent a clinically useful marker of prognosis after an AMI as part of a multimarker strategy targeting the natriuretic neurohormonal pathway.
