Active clinical trials for "Coronary Artery Disease"

The main objective of this study is to evaluate the effectiveness of stent Inspiron ™ sirolimus-eluting and coating the abluminal biodegradable stent Biomatrix Flex ™ lesions in native coronary arteries.

This is a phase 1, single-blind, randomized, placebo-controlled, multiple ascending dose study aimed to assess the safety, tolerability, and pharmacokinetics of GS-6615 in healthy subjects.

The purpose of this study is to assess the effectiveness and safety of rivaroxaban compared with placebo (inactive medication), in reducing the risk of death, myocardial infarction or stroke in participants with heart failure and significant coronary artery disease following an episode of decompensated heart failure.

The use of drug eluting stents (DES) used to treat coronary artery blockages is limited by poor healing of the stented area. This will require the combined use of blood thinners such as aspirin and clopidogrel (i.e. dual anti-platelet therapy (DAPT)) to prevent complications such as clot formation on the stent which may lead to a heart attack. Diabetic patients and those presenting with a heart attack at the time of stent placement are at increased risk for clot formation. However, little is known of the healing responses after stent placement in these populations. Currently all patients receiving DES are advised to complete DAPT for twelve months although more personalized durations of DAPT based on stent healing would reduce both clot formation and potential bleeding from the blood thinners, thereby improving the long-term safety of DES. Intracoronary optical frequency domain imaging (OFDI) is a novel high resolution invasive imaging technique that has the ability to evaluate stent healing at follow-up. Among the commercially available coated stents used in the U.S., the zotarolimus eluting stents (RESOLUTE Integrity, Medtronic, Minneapolis, MN) has demonstrated superior healing in both preclinical and clinical studies. The purpose of this trial is to determine the healing responses of the RESOLUTE Integrity stent as detected by OFDI in patients with and without diabetes presenting with ACS. Specifically, in this observational study, the study team will investigate non-insulin dependent diabetics and non-diabetics in the setting of ACS and RESOLUTE Integrity stent placement. The investigators hypothesize that healing responses in patients with non-insulin dependent diabetes will be similar to those without diabetes presenting with ACS and that a majority of patients will demonstrate complete healing as determined by OFDI measurements.

In view of the lack of large-scale clinical study and potent evidence-based medicine, the investigators designed a randomized, double-blind, placebo-controlled study to ascertain whether preoperative intravenous administration with glutamine can improve the postoperative cardiac function and prognosis of adult patients undergoing cardiac surgery. The investigators want to detect the levels of myocardial protein O-GlcNAc modification and HSP70 expression, changes in sensitive indicators of myocardial injury, systemic inflammatory reaction and oxidative stress levels, and to examine the correlation between these changes and Clinical manifestations. The ultimate goal of the study is to explore a new way for clinical myocardial protection.

The goal of this study is to find out if a drug called selatogrel (ACT-246475) can prevent platelets from binding together when administered by an injection under the skin in the thigh or in the belly. Another goal is to know how fast and for how long selatogrel (ACT-246475) works and if there is a difference if the drug is injected in the thigh or in the belly. This study will also help to find out more about the safety of this new drug.

To determine the efficacy of HS-25 (20mg) in reducing low density lipoprotein-cholesterol (LDL-C) levels after a 12-week period of treatment in combination with Atorvastatin in subjects with hypercholesterolemia and coronary heart diseases; To determine the safety of HS-25 (20mg) combination with Atorvastatin in subjects with hypercholesterolemia and coronary heart diseases

Cardiac rehabilitation (CR) is designed to increase healthy behaviours (e.g. physical activity, healthy eating, smoking abstinence) and reduce risk factors (e.g. high blood pressure & cholesterol) in order to improve quality of life and health among people with heart disease. Unfortunately, few patients attend CR, often reporting several barriers to access including travel distance, parking fees and lack of time. Advances in technology have the potential to improve accessibility and delivery of CR programs, and improve patient empowerment. The University of Ottawa Heart Institute has developed an e-health program called the Virtual Cardiac Rehabilitation Program (VCRP); an online cardiovascular health management system (website & Smartphone app) that provides strategies for the control and management of risk factors. The goals of VCRP are to: empower and educate patients; foster better communication between patients and their health care team; stimulate shared decision making; and, facilitate care coordination leading to better health outcomes. The VCRP provides patients with: real-time access to their health information, as well as tracking of risk behaviours and factors through integration with devices; a wellness plan; access to a personal on-line health coach; goal-setting notifications; on-line community forums; and, circle of care access to information. The aim of this project is to evaluate the effects of VCRP (with integrated fitness tracker) compared to a standard, home-based CR program. The study will look at changes in: patient empowerment; health behaviours; risk factors; quality of life; clinical outcomes; and, costs. The study will improve our understanding of: patient and provider needs; program usability; and shared decision-making. Results will inform the use of e-health programs such as VCRP into healthcare settings to improve patient empowerment, shared decision-making, and the ability to integrate wearable monitors to improve health behaviours.

The purpose of this study was to evaluate the long-term safety and tolerability of ezetimibe 10 mg once daily co-administered with atorvastatin 10 to 80 mg daily for up to 12 consecutive months in participants with heterozygous familial hypercholesterolemia (HeFH) or in participants with coronary heart disease (CHD) or multiple cardiovascular risk factors and primary hypercholesterolemia not controlled by a starting dose (10 mg daily) of atorvastatin.

A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device procedural success of the Scoreflex NC Scoring Percutaneous Transluminal Coronary Angioplasty (PTCA) catheters in subjects with stenotic coronary arteries during percutaneous coronary intervention. Two-hundred (200) subjects will be treated at up to 15 U.S. sites with the Scoreflex NC Scoring PTCA catheter during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through hospital discharge.
