Background Long-term secondary preventive programs in coronary heart disease (CHD) are of highest efficacy but numerous logistical problems often compromise their implementation. Contemporary remote technologies have a potential to overcome these barriers.


To assess  the impact of 2 preventive counselling programs with subsequent remote support in CHD patients with concomitant obesity.


A prospective randomized parallel-group study in 120 stable CHD patients hospitalized for elective coronary revascularization who were from 40 to 65 years old and had concomitant obesity. Patients were randomized (1:1:1) into 3 groups (n=40 each). Before discharge, Groups 1 and 2 received a single-session comprehensive counselling with focus on diet followed by remote counselling by phone (Group 1) or via text messages (Group 2). Remote counselling was delivered weekly (Months 1-3) and then monthly (Months 4-6). Group 3 received only standard advice from their attending physicians. The patients were followed for 12 months with assessment of adiposity measures, self-reported dietary patterns, physical activity (IPAQ questionnaire), smoking status, blood pressure (BP), fasting blood glucose, lipids and C-reactive protein (CRP) levels, as well as of clinical events.


At 1 year of follow-up, the patients from both intervention groups showed a marked improvement of several risk factors including obesity: the body mass index was reduced by 1.48±0.13 kg/m² in Group 1 and by 1.53±0.18 kg/m² in Group 2; the waist circumference went down by 7.62±0.49 and by 7.41±0.74 cm, respectively; the height-normalized fat mass decreased by 4.66±0.40 kg and 5.98±0.63 kg, respectively (all P values are <0.01 vs corresponding changes in the control group). These changes were coupled with more healthy dietary patterns and less sedentary lifestyles in both intervention groups: the proportion of patients with low activity level fell from 87.5% to 2.5% in Group 1 and from 80% to 10% in Group 2 (both p values <0.01 vs control). In Group 1, BP decreased by 18.08±2.20 mmHg (systolic) and 8.56±1.61 mmHg (diastolic); both р values <0.01 vs Group 3. In Group 2 systolic BP dropped by only 11.95±2.50 mmHg (non-significant) and diastolic BP by 6.33±1.52 mmHg (р<0.05 vs control). The proportion of smokers went down from 30% to 5% in Group 1 and from 22.5% to 0% in Group 2 (both p values <0.01 vs control). The fasting glucose levels decreased by 0.21±0.20 mmol/L in Group 1 and by 0.48±0.25 mmol/L in Group 2 (<0.01 vs control, both), but there were no meaningful improvements in blood lipids or CRP.


Long-term (6 months) secondary prevention programs incorporating remote support technologies result into sustained improvement of key secondary prevention indicators in obese CHD patients, irrespective of the support modality (by phone or via electronic messaging).
