Purpos. To assess the effectiveness of preventive counseling with focus on diet modification followed by remote support via telephone on awareness of cardiovascular (CV) risk factors (RFs) in patients (pts) with high/very high CV risk. Material and methods. This is a prospective randomized controlled study of 100 pts with high/very high CV risk (5-9% and ≥10% according to the SCORE scale) and any 2 criteria for metabolic syndrome. Pts were randomized into 2 groups in 1:1 ratio - the intervention group (n=50) and the control group (n=50). The intervention group received comprehensive preventive counseling with focus on diet modification followed by remote preventive counseling by phone every two weeks for the first 3 months after enrollment (a total of 6 sessions). The control group received usual care in Health centers which also included basic preventive counseling. A specially designed questionnaire was used to evaluate the awareness of the basic CV RFs, including open questions. The awareness was assessed at baseline, 6 and 12 months. Results. The groups were well balanced according to demographic and clinical features. The results of the study revealed an extremely low awareness of major CV RFs of pts in both groups at baseline: practically none of them indicated as RFs for cardiovascular disease elevated cholesterol (8,0% and 4,0%, respectively) and blood pressure (14.0% and 4.0%). At 6 month the level of awareness of CV RFs has increased significantly. Moreover, pts of the intervention group were more informed about elevated cholesterol (58,0% vs. 28,0%; p<0,01) and unhealthy diet (76,0% vs. 52,0%; p<0,05). At 12 month the level of awareness of CV RFs was significantly higher in both groups to compare from baseline. Conclusion. Preventive counseling with focus on diet modification followed by 3 months remote support via phone provided a significant improvement of awareness of CV RFs in pts with high/very high CV risk.
