Randomized clinical trial to assess the efficacy of a comprehensive programme of secondary prevention of cardiovascular disease in general practice: the PREseAP study

Abstract

Introduction and objectives: To assess the efficacy of a comprehensive program of secondary prevention of cardiovascular disease in general practice.

Methods: A cluster randomized clinical trial was carried out in a regular general practice setting. Male and female patients aged under 86 years with a diagnosis of ischemic heart disease, stroke or peripheral artery disease were recruited between January 2004 and May 2005. Study participants were seen at 42 health centers throughout the whole of Spain. The primary endpoint was the combination of all-cause mortality and hospital cardiovascular readmission at 3-year follow-up.

Results: In total, 1224 patients were recruited: 624 in the intervention group and 600 in the control group. The primary endpoint was observed in 29.9% (95% confidence interval [CI], 25.5-34.8%) in the intervention group and 25.6% (22.3-29.2%) in the control group (P=.15). At the end of follow-up, 8.5% (6.3-11.3%) in the intervention group and 11% (7.4-16%) in the control group were smokers (P=.07). The mean waist circumference of patients in the intervention and control groups was 100.44 cm (95% CI, 98.97-101.91 cm) and 102.58 cm (95% CI, 100.96-104.21 cm), respectively (P=.07). Overall, 20.9% (15.6-27.7%) of patients in the intervention group and 29.6% (23.9-36.1%) in the control group suffered from anxiety (P=.05), and 29.6% (22.4-37.9%) in the intervention group and 41.4% (35.8-47.3%) in the control group had depression (P=.02).

Conclusions: A comprehensive program of secondary prevention of cardiovascular disease in general practice was not effective in reducing cardiovascular morbidity and mortality. However, some factors associated with a healthy lifestyle were improved and anxiety and depression were reduced.
