Información sobre el riesgo cardiovascular a hipertensos seguidos en atención primaria. ¿Mejora nuestra eficacia?

Abstract

Objectives. To analyse how information to patients on their cardiovascular risk affects the latter's subsequent evolution and to see whether there are differences in the evolution of risk as a function of its being high, moderate, or low. Design. Intervention study of patients who attended our scheduled hypertension clinics. Setting. Health centre on the periphery of Murcia, Spain. Participants. Three hundred patients (139 men and 161 women) from 40 to 75 years old, with essential hypertension, treated or otherwise, controlled or otherwise, in the hypertension programme. They were divided into 3 groups of 100 patients: low, moderate, and high risk. Interventions. There were 2 attendances of each patient: a) initially, at which cardiovascular risk was calculated; half of each risk group were informed of their cardiovascular risk; b) finally, a year later, at which the cardiovascular risk of all the patients was calculated. Main measurements. Calculation of cardiovascular risk on the Framingham scale. Results. No significant differences were appreciated in low and moderate cardiovascular risk groups. In the high-risk group, the informed patients fell from an initial 23.6±2.5% to 20.1±2.6% after a year (P
