ObjectiveTo improve the knowledge of the population about heart-healthy habits through a training program supplemented by a web site and community activities. DesignA controlled clinical trial with intervention done through participation in the Cardiovascular Health Training Classroom (CHTC) LocationA town of 80,000 inhabitants. ParticipantsPatients: both sexes, aged 55 to 70 years, with at least one cardiovascular risk factor (CVRF). InterventionThe intervention group (IG) consisted of patients who participated in the CHTC. Intervention was carried out through a 20-hour presential group course in which a support web site was offered and complementary activities were organized. Classes were taught by three Primary Care nurses. Main measurementsThe primary endpoint was knowledge of CVRF. The secondary variables were age, sex, CVRF, lifestyle, visits to health centers, pharmaceutical use adherence, and satisfaction with the program. ResultsData from patients in the first 10 courses (n=150) were evaluated. A statistically significant improvement was observed in overall knowledge of CVRF in the IG (87.3% to 100%) compared with control group (GC) (84.5% to 92.7%), p<.001, as well as an improvement in physical activity is (IG: 71.2% to 83.1% versus CG: 72.6% to 78.2%), p=.05. The total number of Primary Care visits (medical and nursing) decreased in the IG more than in the CG. The satisfaction rate of the course was very high. ConclusionsThis experience is effective in improving cardiovascular health knowledge and promoting some healthy habits.
