The potential benefit of dual antiplatelet therapy beyond 1 year after a myocardial infarction has not been established. We investigated the efficacy and safety ticagrelor, P2Y12 receptor antagonist with established an acute coronary syndrome, in this context.We randomly assigned, double-blind 1:1:1 fashion, 21,162 patients who had to 3 years earlier ticagrelor at dose 90 mg twice daily, 60 or placebo. All were receive low-dose aspirin followed for median 33 months. primary end point was...

However, few diabetes trials have prospectively evaluated adjudicated as an end point.A total of 16 492 patients with type 2 a history of, or at risk cardiovascular events were randomized to saxagliptin placebo (mean follow-up, 2.1 years). The primary point was the composite death, myocardial infarction, ischemic stroke. Hospitalization for predefined component secondary point. Baseline N-terminal pro B-type natriuretic peptide measured...

Background— Despite the known association of diabetes mellitus with cardiovascular events, there are few contemporary data on long-term outcomes from international cohorts patients mellitus. We sought to describe at 4 years and identify predictors these events in Methods Results— The Reduction Atherothrombosis for Continued Health (REACH) registry is an high risk atherothrombosis or established atherothrombosis. Four-year event rates were determined corrected group prognosis method. Of 45...

Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been hypothesized to be involved in atherogenesis through pathways related inflammation. Darapladib is an oral, selective inhibitor of the Lp-PLA2 enzyme.To evaluate efficacy and safety darapladib patients after acute coronary syndrome (ACS) event.SOLID-TIMI 52 was a multinational, double-blind, placebo-controlled trial that randomized 13,026 participants within 30 days hospitalization with ACS (non-ST-elevation or ST-elevation myocardial...

Dipeptidyl peptidase 4 inhibitors may have a protective effect in diabetic nephropathy.We studied renal outcomes of 16,492 patients with type 2 diabetes, randomized to saxagliptin versus placebo and followed for median 2.1 years the Saxagliptin Assessment Vascular Outcomes Recorded Patients Diabetes Mellitus-Thrombolysis Myocardial Infarction 53 (SAVOR-TIMI 53) trial.At baseline, 9,696 (58.8%) subjects had normoalbuminuria (albumin/creatinine ratio [ACR] <30 mg/g), 4,426 (26.8%)...

OBJECTIVE The glycemic management of patients with type 2 diabetes mellitus (T2DM) and renal impairment is challenging, few treatment options. We investigated the effect saxagliptin in Saxagliptin Assessment Vascular Outcomes Recorded Patients Diabetes Mellitus (SAVOR)-Thrombolysis Myocardial Infarction (TIMI) 53 trial according to baseline function. RESEARCH DESIGN AND METHODS T2DM at risk for cardiovascular events were stratified as having normal or mildly impaired function (estimated...

AimsTicagrelor reduced major adverse cardiovascular event (MACE) by 15–16% in patients with prior myocardial infarction (MI) PEGASUS-TIMI 54. We hypothesized that who recently discontinued P2Y12 inhibition, even years after MI, may be at particular risk of MACE and derive benefit from continuation or reinitiation therapy.

Sodium-glucose cotransporter 2 inhibitors, such as dapagliflozin, promote renal glucose excretion and reduce cardiovascular (CV) deaths hospitalizations for heart failure (HHF) among patients with type diabetes. The relative CV efficacy safety of dapagliflozin according to baseline kidney function albuminuria status are unknown.

In acute coronary syndrome (ACS), potassium levels <3.5 mEq/L are associated with ventricular arrhythmias. Current guidelines therefore recommend a target >4.0 in ACS. Our study evaluated the association between levels, cardiac arrhythmias, and cardiovascular death patients non-ST-segment elevation myocardial infarction or unstable angina. Potassium were measured 6515 prior to randomization receive either ranolazine placebo MERLIN-TIMI 36 trial. A seven-day continuous electrocardiographic...
