Active clinical trials for "Coronary Artery Disease"

For the treatment of primary large-diameter coronary atherosclerosis through percutaneous coronary intervention (PCI), the use of a drug balloon (DCB) is not inferior to the placement of a drug-eluting stent (Firehawk™ family). * Large-diameter vessels were defined as vessels with a diameter of ≥3.00 mm and ≤ 4.0mm

Coronary calcified lesion is associated with a poor clinical outcome. Intravascular ultrasound (IVUS) provides anatomic information in detail about reference vessel dimensions and lesion characteristics including severity of diameter stenosis, lesion length, and morphology. Both randomized and observational studies have reported the clinical benefits of IVUS guidance for patients with chronic total occlusion (CTO), long lesions, acute coronary syndrome (ACS) with complex bifurcation lesions. Our previous ULTIMATE trial has demonstrated that IVUS-guided drug-eluting stent (DES) implantation significantly improved clinical outcome in all-comers, particularly for patients who had an IVUS-defined optimal procedure, compared with angiography guidance. However, the benefit of IVUS guidance in coronary severe calcification still remains unknown in the modern DES era.

Study design Prospective randomized open labeled multicenter study Hypotheses In asymptomatic patients with ≥ 10% of myocardial ischemia: PCI (Percutaneous Coronary Intervention) with latest generation of drug eluting stents is superior to optimal medical therapy in terms of relative reduction in MACCE (Major Adverse Cardiovascular and Cerebrovascular events). In symptomatic patients with ≥ 5% of myocardial ischemia: PCI with latest generation of drug eluting stents is superior to optimal medical therapy (OMT) in terms of improved life quality measured as an increase of SAQ (Self Assessment Questionnaire) score of 8 points after 6 months. Inclusion Criteria CTO in native coronary artery Myocardial ischemia in a territory supplied by CTO assessed by nuclear imaging. Age ≥18 yrs. Able to provide written Informed consent and willing to comply with the specified follow-up contacts Target artery ≥ 2.5 mm Prior to randomization all patients undergo 3 months of OMT. Subsequently the population will be divided into: Cohort A: Asymptomatic (CCS < 2 and SAQ QoL > 60) patients with myocardial ischemia (≥ 10% of LV) in a territory supplied by CTO Cohort B: Symptomatic patients (CCS class ≥ 2 and/or SAQ QoL score ≤ 60 after treating non CTO lesions and after OMT) with Myocardial ischemia (5% of LV) in a territory supplied a CTO Cohort C: patients enrolled but not randomized in cohort A or B Exclusion criteria (for both cohort A and B) NSTEMI or STEMI within 1 month Coronary anatomy not suitable for CTO-procedure Coronary artery disease involving the left main/three-vessel disease with indication for CABG following heart team conference Life expectancy < 2 years Severe chronic pulmonary disease (FEV1 < 30 % of predicted value) Contraindication to dual anti-platelet therapy Pregnancy eGFR < 30 mL/min/1.73 m2 In multi-vessel disease: if it is deemed unsafe to treat the non-CTO lesion first. Severe valvular heart disease Primary endpoint Cohort A: Composite endpoint of MACCE (all-cause mortality, stroke, any myocardial infarction, clinically driven revascularization*), hospitalization for heart failure or incidence of malignant arrhythmias. *CCS class ≥ 2 and/or QoL score < 60. Same criteria used as for allocation to Cohort B Cohort B: SAQ Quality of Life Assessment after 6 months. Number of patients 1,560 (1200 in cohort A/360 in cohort B Follow up time Cohort A: 5 years Cohort B: 6 months

The central hypothesis of ROMA:Women is that the use of multiple arterial grafting (MAG) will improve clinical outcomes and quality of life (QOL) compared to single arterial grfating (SAG). The specific aims of ROMA:Women are: Aim 1: Determine the impact of MAG vs SAG on major adverse cardiac and cerebrovascular events in women undergoing coronary artery bypass grfating (CABG). The investigators will compare major adverse cardiac and cerebrovascular events (death, stroke, non-procedural myocardial infarction, repeat revascularization, and hospital readmission for acute coronary syndrome or heart failure) in a cohort of 2,000 women randomized 1:1 to MAG or SAG (690 from the parent ROMA trial + 1,310 from ROMA:Women). Differences by important clinical and surgical subgroups (patients younger or older than 70 years, diabetics, racial and ethnic minorities, on vs off pump CABG, type of arterial grafts used) will also be evaluated. The women enrolled in the ongoing ROMA trial (anticipated to be approximately 690) will be included in ROMA:Women, increasing efficiency and reducing enrollment time. Hypothesis 1.0. MAG will reduce the incidence of major adverse cardiac and cerebrovascular events. Hypothesis 1.1. The improvement with MAG will be consistent across key subgroups. Aim 2: Determine the impact of MAG vs SAG on generic and disease-specific QOL, physical and mental health symptoms in women undergoing CABG. The investigators will compare generic (SF-12, EQ-5D) and disease-specific (Seattle Angina Questionnaire) QOL and physical and mental health symptoms (PROMIS-29) in a sub-cohort of 500 women randomized 1:1 to MAG or SAG (including those enrolled in ROMA:QOL). Differences by important subgroups (as defined above) will also be evaluated. Hypothesis 2.0. MAG will improve generic and disease-specific QOL compared to SAG. Hypothesis 2.1. MAG will improve physical and mental health symptoms compared to SAG. Hypothesis 2.2. The improvement with MAG will be consistent across key subgroups.

This is a prospective, multi-center, single-group post-market study. It is planned to be carried out in about 3 clinical institutions, and a total of 60 subjects are expected to be enrolled.

Beta-blockers have the greatest cardiovascular impact in patients with reduced heart function/heart failure and in reducing the peri-operative risk of atrial fibrillation. In patients without these high-risk features treated with coronary artery bypass graft (CABG) surgery, their continued long-term role is unclear.

To assess if an angiographic follow-up at 6 months after Percutaneous Coronary Intervention in Left Main Coronary Artery Disease decrease the composite objective of death, myocardial infarction, and stroke at 36 months.

Proprotein convertase subtilisin/kexin type 9 inhibitor monoclonal antibodies (anti-PCSK9) significantly reduce the serum LDL-C level, leading to a regression of the coronary epicardial plaque demonstrated by intracoronary ultrasonography (IVUS), as well as cardiovascular events (CV) in patients with atherosclerotic CV disease treated with statin. The impact of PCSK9 inhibition on coronary microcirculation has never been assessed. However, microvascular coronary dysfunction (CMVD) is a powerful prognostic marker, irrespective of conventional CV risk factors, but also of the severity of the epicardial coronary involvement detected during coronary angiography. The investigators hypothesized that anti-PCSK9 would decrease CMVD, measured by the microcirculatory resistance index (MRI) during coronary angioplasty (Percutaneous coronary intervention, PCI) in patients with myocardial ischemia proved in myocardial scintigraphy.

This study compares a new method of treating severely calcified coronary lesions, the intracoronary lithoplasty, with the current gold standard, the rotablation.

The purpose of this study is to assess if using the Impella® CP (or Impella® 2.5) device during high-risk PCI in patients with reduced left-sided heart function will result in an improvement in symptoms, heart function and health after a heart procedure compared to the current standard of care.
