Details and patient eligibility

About

People with Coronary Artery Disease (CAD) have narrow or blocked arteries that supply blood to the heart. Reduced blood flow to the heart muscle from CAD can cause chest pain or aching, especially with exercise or activity. CAD can lead to weakening of the heart muscle or heart failure, and a higher risk of heart attack or death. Certain proteins in the blood, known as biomarkers, can be found in people with CAD. Higher levels of these biomarkers are associated with a greater risk of complications from CAD. The purpose of this study is to see if a customized treatment based on biomarkers will reduce the biomarker levels and lead to lower risk of complications from CAD.

Full description

People with Coronary Artery Disease (CAD) have narrow or blocked arteries that supply blood to the heart. Reduced blood flow to the heart muscle from CAD can cause chest pain or aching, especially with exercise or activity. CAD can lead to weakening of the heart muscle or heart failure, and a higher risk of heart attack or death. Certain proteins in the blood, known as biomarkers, can be found in people with CAD. Higher levels of these biomarkers are associated with a greater risk of complications from CAD. The purpose of this study is to see if a customized treatment based on biomarkers will reduce the biomarker levels and lead to lower risk of complications from CAD.

Participants with high biomarker levels will be randomly assigned (like flipping a coin) to either the treatment group or usual care. Both groups will have physical exams, blood tests, and answer questionnaires. Participants in the treatment group will have their medications adjusted based on their biomarker levels. They will also be asked to make lifestyle changes like diet, exercise, and quitting smoking. Participants in the usual care group will receive the standard of care prescribed by their doctor.

This study will take place in research rooms at Emory University Hospital and the Woodruff Memorial Research Building.

Participants will be paid for being in the study.

Participants will be recruited from Emory Healthcare outpatient cardiology clinics and cath labs. Participants will be identified through the medical record and by their doctors. Written consent will be obtained from Participants before they can join the study.

Study data and blood samples will be collected and banked for possible research in the future. These may also be shared with other researchers including researchers outside of Emory.

This study will advance scientific knowledge and benefit human health by giving us more treatment options for CAD.

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

276 participants in 3 patient groups

Optimization Group

Experimental group

Description:

Participants with CAD and a BRS greater than 0 who are randomized to the Optimization Group have treatment goals that include achieving LDL-C\<70 mg/dL, hemoglobin A1c \<7%, blood pressure \<130/80 mmHg, smoking cessation, at least 30 minutes of moderate-intensity aerobic activity 5 days a week and weight loss to body mass index \<30 kg/m2. To achieve these goals, both pharmacological and lifestyle interventions will be considered and individualized for each patient.

Treatment:

Other: Medical/Behavioral therapy

Usual Care Group

Active Comparator group

Description:

Participants with CAD and a BRS greater than 0 who are randomized to the usual care group will receive standard of care therapy prescribed by their primary care physician and/or cardiologist. Patients and their physicians will be informed that their BRS is ≥1 and they have been randomized to the usual care group.

Treatment:

Other: Standard of Care

Registry Group

Other group

Description:

Participants with BRS of 0 at baseline and after 3 months will undergo follow-up including measurements of BRS at the time-points specified for the randomized subjects and also for adverse events. Laboratory results and questionnaire data will be obtained on the phone.

Treatment:

Other: Registry
