Right ventricular function in patients with pulmonary regurgitation with versus without tetralogy of Fallot.
Right ventricular (RV) dilation from pulmonary valve regurgitation (PR) is common after intervention(s) for pulmonary stenosis (PS) or atresia and intact ventricular septum (PA/IVS). It is not well established whether PR and RV dilation have similar effects on RV function and exercise capacity in these patients compared to patients after repair of tetralogy of Fallot (rToF). The aims of this study were to compare exercise tolerance, RV function and myocardial mechanics in non-ToF versus rToF children with significantly increased and comparable RV volumes. ⋯ Global RV function and exercise capacity are similarly reduced in non-ToF and rToF patients with severely dilated RV, after matching by RVEDVi, suggesting a comparable impact of RV dilation on RV global function. The significance of reduced RV longitudinal function and worse dyssynchrony in rToF patients require further exploration.

Randomized Controlled Trial Multicenter StudyRandomized evaluation of ticagrelor monotherapy after 3-month dual-antiplatelet therapy in patients with acute coronary syndrome treated with new-generation sirolimus-eluting stents: TICO trial rationale and design.
Ticagrelor monotherapy after short-term dual-antiplatelet therapy (DAPT) may optimize ischemic and bleeding risks, particularly for acute coronary syndrome (ACS) patients, because its strategy is less potent than ticagrelor-based DAPT but more potent than aspirin or clopidogrel monotherapy. ⋯ The TICO trial is an ongoing trial evaluating the efficacy and safety of ticagrelor monotherapy following 3-month DAPT exclusively in ACS patients treated with uniform BP-SES. It may provide novel insights regarding the need for adjusted use of DAPT for rebalancing risk-benefit in current practice and changing from the conventional concept of aspirin maintenance to a ticagrelor-based regimen in the management of ACS.

Multicenter Study Clinical TrialAdverse events in patients with high platelet reactivity following successful chronic total occlusion PCI: The Assessment of Dual AntiPlatelet Therapy with Drug-Eluting Stents (ADAPT-DES) study.
Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) typically requires a greater number of stents and longer stent length than non-CTO PCI, placing these patients at greater risk for adverse ischemic events. We sought to determine whether the association between high platelet reactivity (HPR) and the risk of ischemic events is stronger after CTO than non-CTO PCI. ⋯ In ADAPT-DES, HPR was associated with an increased 2-year risk of TVF after PCI, an association that was at least as strong after CTO PCI compared with non-CTO PCI.

Meta Analysis Comparative StudyComparative effectiveness and safety of statins as a class and of specific statins for primary prevention of cardiovascular disease: A systematic review, meta-analysis, and network meta-analysis of randomized trials with 94,283 participants.
The current guidelines of statins for primary cardiovascular disease (CVD) prevention were based on results from systematic reviews and meta-analyses that suffer from limitations.

Randomized Controlled Trial Multicenter StudyA randomized, double-blind, placebo-controlled trial to assess the efficAcy and safety of Trimetazidine in patients with angina pectoris having been treated by percutaneous coronary intervention (ATPCI study): Rationale, design, and baseline characteristics.
About 30% of angina patients have persisting symptoms despite successful revascularization and antianginal therapy. Moreover, in stable patients, percutaneous coronary intervention (PCI) does not improve survival as compared with medical therapy alone. Trimetazidine, an antianginal agent devoid of hemodynamic effect, may help reducing symptoms and improving outcomes after PCI. The ATPCI study is investigating the efficacy and safety of adding trimetazidine to standard-of-care in angina patients who had a recent PCI. ⋯ The ATPCI study will shed further light on the management of contemporary angina patients after PCI. Results are expected in 2019.
