Dietary Intervention to Stop COronary Atherosclerosis in Computed Tomography

The Effect of Strict Dietary Intervention on Atherosclerotic Lesions in Patients Diagnosed With Coronary Artery Disease, Assessed by Coronary Computed Tomography Angiography (CCTA).

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.

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.

Inclusion Criteria:

• coronary atheroslerotic lesions confirmed in the screening CCTA with reduction of the artery diameter less than 70% in 2 or more coronary artery segments
• no indications for coronary angiography / revascularization (no documented significant ischemia of myocardium)
• free and informed consent of the person concerned
• willingness to follow the strict directions given by the investigators

Exclusion Criteria:

• any valvular heart disease requiring cardiac surgery (or expected cardiac surgery intervention within 12 moths)
• diagnosis of dilated / hypertrophic cardiomyopathy
• diagnosis of DM t. 2
• past CABG procedure
• women in reproductive age
• known genetic factors with a possible impact on the progres of coronary atherosclerotic lesions (e. i. congenital metabolic disorders, familial hyperlipidemias)
• low quality of the CCTA data
