Primary objective: To evaluate the impact of 12 weeks' administration of extended release niacin/laropiprant (ERN/LRPT) compared to placebo added to statin therapy on endothelial dependant dilatation of the arterial wall assessed by brachial vasoreactivity in stable coronary heart disease (CHD) patients. Secondary objective: To evaluate the impact of 12 weeks' administration of extended release niacin/laropiprant (ERN/LRPT) compared to placebo added to statin therapy on serum lipids and the parameters of inflammation in stable coronary heart disease (CHD) patients. CHD-coronary heart disease ER-extended release

The main purposes of this study is to analyze, in a randomized controlled trial, the effects of an exercise-based cardiac rehabilitation program (i) on biomarkers of endothelial function, (ii) on biomarkers of inflammation, (iii) on autonomic function, and (iv) on arterial stiffness in coronary artery disease patients (CAD). Additionally, the investigators aim to analyze the (v) contribution of age and the changes in traditional risk factors to the modification of the endothelial dysfunction and inflammation, and (vi) the contribution of the changes in inflammatory and endothelial function biomarkers to the modification of autonomic function and arterial stiffness. The investigators hypothesize that exercise training will improve the autonomic function, arterial stiffness and mitigate the endothelial dysfunction and inflammation in CAD patients even in the absence of significant changes in traditional risk factors. Thus, the investigators expect with the present study to promote, develop and expand the knowledge in this field by assessing the impact of exercise on a pool of markers that provide a wide picture of the pathophysiological processes underlying CAD.

It is the aim of the study to compare the effects of 6 weeks of either high-intensity interval training (HIT; carried out at correctly assessed 85-95% of maximal heart rate), pyramid, or continuous endurance training, on changes of physical exercise capacity in cardiac patients. The three exercise arms (isocaloric) are composed as follows: Endurance training (n=15): 31min at 65-75% HRmax; HIT (n=15): 4x4min intervals at 85-95% HRmax divided by 3x3min of active recovery at 60-70% HRmax, making it a total of 25min; Pyramids (n=15): One Pyramid consists of 8 one-minute blocks. Those are grouped starting with one block of 70-75% HRmax, followed by one block at 75-80% HRmax and another one at 80-85% HRmax. The top of the pyramid are 2 blocks of 85-90% HRmax. Intensity is lowered afterwards with one block at 80-85% HRmax, followed by one block at 75-80% HRmax and last one at 70-75% HRmax. Two more pyramids follow, each divided by 2min of active recovery at 65-70% HRmax, making it a total of 28min. All protocols are initiated by 5min of warm-up and end with 5min of cool-down, both at 60-70% HRpeak. Primary Outcome: Individual maximum power output in watt (Pmax). Secondary Outcome: Change of power output in watt at lactate thresholds at 2 and 4 mmol/l.

This study is designed to provide an assessment of the change in baseline lipid parameters with RVX000222 after 12 weeks and 24 weeks of treatment when given in addition to optimized statin background therapy in subjects with low baseline HDL-C.

The purpose of the ISCHEMIA trial is to determine the best management strategy for higher-risk patients with stable ischemic heart disease (SIHD). This is a multicenter randomized controlled trial with 5179 randomized participants with moderate or severe ischemia on stress testing. A blinded coronary computed tomography angiogram (CCTA) was performed in most participants with eGFR ≥60 mL/min/1.73m2 to identify and exclude participants with either significant unprotected left main disease (≥50% stenosis) or those without obstructive CAD (<50% stenosis in all major coronary arteries). Of 8518 participants enrolled, those that had insufficient ischemia, ineligible anatomy demonstrated on CCTA or another exclusion criterion, did not go on to randomization. Eligible participants were then assigned at random to a routine invasive strategy (INV) with cardiac catheterization followed by revascularization, if feasible, plus optimal medical therapy (OMT) or to a conservative strategy (CON) of OMT, with cardiac catheterization and revascularization reserved for those who fail OMT. SPECIFIC AIMS A. Primary Aim The primary aim of the ISCHEMIA trial is to determine whether an initial invasive strategy of cardiac catheterization followed by optimal revascularization, if feasible, in addition to OMT, will reduce the primary composite endpoint of cardiovascular death, nonfatal myocardial infarction, resuscitated cardiac arrest, or hospitalization for unstable angina or heart failure in participants with SIHD and moderate or severe ischemia over an average follow-up of approximately 3.5 years compared with an initial conservative strategy of OMT alone with catheterization reserved for failure of OMT. B. Secondary Aims Secondary aims are to determine whether an initial invasive strategy compared to a conservative strategy will improve: 1) the composite of CV death or MI; 2) angina symptoms and quality of life, as assessed by the Seattle Angina Questionnaire; 3) all-cause mortality; 4) net clinical benefit assessed by including stroke in the primary and secondary composite endpoints; and 5) individual components of the composite endpoints. Condition: Coronary Disease Procedure: Coronary CT Angiogram Procedure: Cardiac catheterization Phase: Phase III per NIH Condition: Cardiovascular Diseases Procedure: Angioplasty, Transluminal, Percutaneous Coronary, other catheter-based interventions Phase: Phase III per NIH Condition: Heart Diseases Procedure: Coronary Artery Bypass Surgery Phase: Phase III per NIH

Attenuated plaque ≥ 5mm by intravascular ultrasound(IVUS) was reported to be high risk for distal embolism in Acute coronary syndrome(ACS). The purpose of this study is to assess the effect of thrombus aspiration catheter and distal protection device (filter wire; Filtrap™) in the aforementioned subgroup of patients at high risk for distal embolism.

This study will evaluate the efficacy of ranolazine as compared with placebo when used as part of standard medical therapy in chronic angina subjects with incomplete revascularization post-percutaneous coronary intervention (PCI; formerly known as angioplasty with stent) on the composite of ischemia-driven revascularization or ischemia-driven hospitalization without revascularization.

The study aims to further assess the safety, efficacy and the performance of its delivery system of FIREHAWK rapamycin-eluting stent up to five years.

The purpose of this study is to evaluate the potential benefit of targeting patients' expectations before coronary artery bypass graft surgery through a brief psychoeducational intervention.
