Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to determine, wheather strict dietary intervention with the use of the DASH diet atop of optimal medical treatment reduces previously diagnosed coronary atherosclerotic lesions assessed witch coronary computed tomography.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A total of 180 patients with coronary atheroslerotc lesions confirmed in coronary computed tomography (CCT) will be analyzed in a 12-month observation time. Patients will be randomized to two groups in a 1:1 fashion. 1 - optimal medical treatment, 2 - strict dietary intervention with implementation of the DASH diet atop of optimal medical treatment. CCT scans will be performed at screening and at 12 months after randomization. Computed tomography imaging data describing atheroslerotic lesions will be assessed.

Study Groups

Dietary And Lifestyle Counseling

Patients receiving strict dietary counseling (implementation of the DASH diet) and lifestyle changes support atop of optimal medical treatment as per 2013 ESC guidelines on the management of stable coronary artery disease.

Group Type EXPERIMENTAL

Dietary And Lifestyle Counseling

Intervention Type BEHAVIORAL

The DASH (Dietary Approaches to Stop Hypertension) diet is a dietary pattern of proven effect on arterial blood pressure reduction. It is rich in fruits, vegetables, whole grains, and low-fat dairy foods; includes meat, fish, poultry, nuts, and beans; and is limited in sugar-sweetened foods and beverages, red meat, and added fats. Dietary counseling will be provided during each of 7 control visits within the 12-month time of observation.

Optimal Medical Treatment

Intervention Type OTHER

Optimal Medical Treatment as per 2013 ESC Guidelines on the Management of Stable Coronary Artery Disease.

Optimal Medical Treatment
