NCT ID: NCT04935086 Enrolling by invitation - Clinical trials for Coronary Artery Disease

Risk Factors for Predictors of MACEs After RA-CABG

Start date: June 30, 2021
Phase:
Study type: Observational

As the secondary choice of artery grafts, radial artery is more and more used to achieve multiple arterial revascularization in CABG. Risk factors for predictors of major cardiovascular adverse events (MACE) after CABG using radial-artery grafts (RA-CABG), however, remain uncertain. This case-control study aims to identify the baseline predictors of MACE after RA-CABG. We will collect the baseline characteristics and perioperative data of patients underwent RA-CABG from Jan. 2009 to Dec. 2019 in our single center. By reviewing the latest follow-up records, we will examine the correlation between the baseline characteristics and clinical outcomes (MACEs), then identify the independent risk factors for predictors of MACEs after RA-CABG.

NCT ID: NCT04810364 Enrolling by invitation - HIV Infections Clinical Trials

HIV Infection And Evolvement of Atherosclerotic Plaque

HIVE
Start date: January 5, 2020
Phase:
Study type: Observational [Patient Registry]

In a prospective multi-center observational study, 200 HIV-infected patients treated with antiretroviral treatment (ART) and who suffered from coronary artery disease (CAD) will be enrolled. Blood samples for biological parameters will be collected with all participants: lipid profile and markers of systemic inflammation specific for HIV-infection (lipopolysaccharide-binding protein; cytokines: IL-1β, IL-6, IL-8, IL-10, TNF -α, INF-γ, INF-α; procalcitonin; inflammatory hsCRP). All of them will undergo functional testing (Echo, CMR both at rest and stress if necessary) and invasive imaging with QCA, FFR, QFR, OCT, IVUS, VH-IVUS, NIRS. Patients will be treated according to the current and previous recommendations. Both medical treatment and percutaneous transluminal coronary angioplasty (PTCA) with or without stenting will be done. Collected data will be analyzed: correlation between ART, blood test results, coronary angiography results, including performed PTCA, history of myocardial infarctions, and other cardiovascular events. The follow-up period will achieve 12 months prospectively with collected clinical events and imaging outcomes which will be determined at the baseline and 12-month follow-up. The independent ethics expertise will be provided by the Central Clinical Hospital of the Russian Academy of Sciences (Moscow, Russia). The monitoring of the clinical data with imaging will be provided by The Ethics Board of Central Clinical Hospital of the Russian Academy of Sciences.

NCT ID: NCT04789278 Enrolling by invitation - Clinical trials for Coronary Artery Disease

Incidental Coronary Calcification Quality Improvement Project

ICC QI
Start date: March 30, 2021
Phase: N/A
Study type: Interventional

This is a multi-center, randomized quality improvement project. At least 200 statin-naïve patients without a history of atherosclerotic cardiovascular disease with incidental coronary artery calcium (CAC) on a prior non-gated chest CT will be enrolled across the Stanford Healthcare System and the Palo Alto Veteran's Affairs Healthcare System. Patients will be randomized in a 1:1 fashion to notification or usual care arms. The primary aim of this project is to estimate the increase in 6-month statin prescription among statin-naïve patients without a history of atherosclerotic cardiovascular disease with incidental CAC on a non-gated chest CT who are randomized to receive notification of their findings vs. usual care.

NCT ID: NCT04744571 Enrolling by invitation - Clinical trials for Coronary Artery Disease

Safety and Efficacy of Drug-Coated Balloon Angioplasty for the Treatment of Chronic Total Occlusions

Start date: February 2021
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate the safety and efficacy of drug-coated balloon angioplasty for the treatment of chronic total occlusions patients with chronic total occlusion (CTO) lesion.

NCT ID: NCT04680338 Enrolling by invitation - Clinical trials for Cardiovascular Diseases

Early Detection of Silent Myocardial Ischemia

EarlySynergy
Start date: May 27, 2019
Phase: N/A
Study type: Interventional

Early-Synergy investigates a diagnostic imaging approach in asymptomatic individuals from the general population for early detection of silent myocardial ischemia and cardiac dysfunction. The diagnostic imaging approach consists of cardiac computed tomography for coronary artery calcium scoring (CT-CAC) and cardiac magnetic resonance (CMR) stress perfusion imaging. Early-Synergy investigates the effect of early detection of silent myocardial ischemia and cardiac dysfunction by CMR in asymptomatic individuals with increased CAC. In addition, the diagnostic yield of CMR for early detection of silent myocardial ischemia and cardiac dysfunction is investigated. Asymptomatic individuals at increased risk (CAC ≥ 300) are therefore randomized 1:1 to either CMR stress perfusion imaging or a control group.

Evaluating Infrasonic Hemodynography

Start date: January 4, 2021
Phase: N/A
Study type: Interventional

This comparative diagnostic accuracy study will determine the accuracy of a noninvasive wearable infrasonic sensor to detect the mechanical, electrical, and hemodynamic function of the cardiovascular system.

NCT ID: NCT04223882 Enrolling by invitation - Clinical trials for Stress, Psychological

Stress Management in Patients With Coronary Artery Disease

Start date: February 3, 2020
Phase: N/A
Study type: Interventional

Introduction: Stress can cause hemodynamic and metabolic changes that contribute to endothelial dysfunction and there is a significant association between high stress and cardiovascular events. Objective: To evaluate the influence of stress management on endothelial function in patients undergoing percutaneous coronary intervention (PCI). Methods: Randomized, controlled, parallel, intention-to-treat clinical trial. Will be considered eligible patients who underwent percutaneous coronary intervention and who have high stress (above average for the Brazilian population) in the Perceived Stress Scale (PSS-10). Patients will be evaluated on PCI admission and stress management with cognitive behavioral techniques will be implemented one month after hospital discharge in the intervention group. Group sessions will be held between 6-9 people. There will be 4 1-hour meetings for 8 weeks. The primary outcome will be the difference in the variation of brachial artery flow-mediated dilatation (FMD) between the groups and at 3 months of baseline evaluation and at 6-month follow-up after the intervention and the secondary outcome will be the difference in the variation of the velocity of brachial artery. Pulse wave evaluated at the same time periods as DMF. Outcomes will be evaluated by Generalized Estimation Equations (GEE). Expected Results: In patients undergoing high-stress percutaneous coronary intervention, the use of cognitive behavioral techniques for stress management will improve endothelial function and vascular stiffness.
