Abstract
Objetivo
Analizar el riesgo coronario, el tratamiento prescrito y determinar si tras un período se modifica el riesgo coronario (RC) de la población con hipercolesterolemia en atención primaria (AP).
Diseño
Observacional transversal.
Emplazamiento
Población consultante en un equipo de AP urbano de Madrid.
Pacientes
Quinientos ochenta y tres pacientes diagnosticados de hipercolesterolemia de ambos sexos y mayores de 25 años que constan en el registro de morbilidad, seleccionados aleatoriamente.
Mediciones y resultados principales
El RC determinado por el método de Framingham lo consideramos alto si es > 20% a los 10 años. Los pacientes con enfermedad cardiovascular (ECV) inicial tienen prescritos hipolipemiantes la mitad de ellos, con más frecuencia los más jóvenes, presentando un colesterol final de 220 mg/dl de media. Entre los pacientes sin ECV inicial, un 32,5% (28,0-36,7%) tiene un RC > 20% y éstos presentan 4,9% (3,0-8,2) más probabilidad de recibir fármacos que los que lo tienen inferior. La prescripción de hipolipemiantes está explicada en un 68% por el RC elevado y la historia familiar de cardiopatía isquémica. Tras al menos un año de seguimiento, constatamos una reducción en la proporción de pacientes con RC alto (diferencia relativa de proporciones 28,7% [20,4-37,1]).
Conclusión
La mitad de los pacientes con ECV o con un RC elevado sin ECV reciben hipolipemiantes. La mayor parte de la prescripción de fármacos está asociada al RC y en la consulta de AP se consigue disminuir la prevalencia de sujetos con RC elevado.

Abstract
Objective
In patients with hypercholesterolaemia determinate the prevalence of high coronary risk (CR), study the lipid lowering treatment applied and determinate if there is any change in CR after a period of treatment.
Design
Cross-sectional.
Emplacement
Primary care.
Patients
583 patients with hypercholesterolaemia both sex, older than 25 years registred in chronic morbility, aleatoried seleccioned.
Measurement and results
Applying the Framingham coronary multivariate risk method we estimate high CR > 20%. Patients with a previous history of cardiovascular event, were treated in a 50%, more frequently younger subjects, rising 220 mg/dl of final cholesterol level. Patients without any cardiovascular event known, the 32.5% (28.0-36.7%) have a CR > 20%. Subjects with high CR have 4.9 (3.0-8.2) more probability if receiving treatment than the others with lower risk. The lipid-lowering treatment is explained in a 67% because the high CR and the familiy history of coronary event. After at least one year period there is a reduction in those with high CR (diference relative of proportions 28.7% [20.4-37.1]).
