Resumen
Objetivos

Evaluar el cumplimiento del tratamiento antiagregante con clopidogrel en pacientes con claudicación intermitente, analizar los factores de riesgo (FR) clásicos y su control en el tiempo y evaluar la correlación del test de elevación de tobillo y la claudicometría, el conocimiento de la enfermedad por parte delpaciente y la evolución de la calidad de vida.

Pacientes y métodos

Serealizó un estudio epidemiológico, de observación, prospectivo y multicéntrico. Se incluyeronpacientes con claudicación intermitente y elseguimiento fue de 6meses. a cadapaciente se le realizó: índice tobillo/brazo, claudicometríay test de elevación del tobillo, test de cumplimiento autocomunicado de Haynes-Saccket, cuestionario de Batalla, cuestionario de salud SF-12, índice de actividad de Duke y analítica, en cada visita. Las variables se analizaron mediante el test χ2, test F-Fisher, y testsigned-rank para datos pareados. Se consideraron estadísticamente significativos valores de p> 0,05.

Resultados

De los 928 pacientes incluidos, completaron las tres visitas 372. El cumplimiento del tratamiento fue del 98,5%. A los 6 meses, tan sólo el 20,8% de los pacientes conocían la enfermedad, y el único FR que mejoró fue el tabaquismo (p= 0,04). La calidad de vida disminuía con relación a la población general. El test de elevación del tobillo y la claudicometría mostraron una correlación significativa (Pearson= 0,84).

Conclusiones

Apesar de que elcumplimiento deltratamiento es muy elevado, la mayoría de los pacientes con claudicación intermitente no tienen un conocimiento preciso de su enfermedad.El control de los FR tras 6 meses de seguimiento no es adecuado.

Summary
Aims

The aim of this study was to evaluate clopidogrel antiaggregant therapy compliance in patients with intermittent claudication. We also sought to analyse the classical riskfactors (RF) and their control over time, and to evaluate the correlation of the ankle-raising test and treadmill exercise testing, the patient's knowledge of the disease and how quality of life progresses.

Patients and methods

We conducted aprospective, multicentre epidemiological study based on observation. The sample was made up of patients with intermittent claudication, who were monitored over a 6-month period. Each patient was submitted to the following tests: Ankle-Brachial lndex, treadmill exercise testing and ankle-raising test, Haynes-Sackett self-reported compliance test, the Batalla survey, the SF-12 health survey, the Duke activity index and analyses on each visit. The variables were analysed by means of the chi-squared test, Fisher's F test, and Signed-rankfor paired data test. Values of p < 0.05 were considered to be statistically significant.

Results

Of the 928 patients included in the study, 372 completed the three visits. Therapy compliance was 98.5%. At six months only 20.8% of the patients knew the disease and the only RF that improved was smoking (p= 0.04). Quality of life diminished in relation to the general population. The ankle-raising test and treadmill exercise testing showed a significant correlation (Pearson= 0.84).

Conclusions

Although therapy compliance is very high, most patients with intermittent claudication do not have accurate knowledge of the disease they are suffering from. After 6 months'follow-up, the control of RF is not adequate.

Resumo
Objectivos

Avaliar a adesão ao tratamento antiagregante com clopidogrel em doentes com claudicação intermitente. Analisar os factores de risco (FR) clássicos e seu controlo no tempo, avaliar a correlação do teste de elevação do tornozelo e claudicometria, o conhecimento da doençapor parte do doente e a evolução da qualidade de vida.

Doentes e métodos

Estudo epidemiológico, de observação, prospectivo e multicêntrico. Foram incluídos doentes com claudicação intermitente e o seguimento foi de 6 meses. Em cada doente realizou-se: índice tornoze-lo/braço, claudicometria e teste de elevação do tornozelo, teste de adesão autocomunicada de Haynes-Saccket, questionário de Batalla, questionário de saúde SF-12, índice de actividade de Duke e analítica em cada visita. As variáveis foram analisadas pelo teste do chi-quadrado, teste F-Fisher e teste Signed-rank para dados emparelhados. Consideraram-se estatisticamente significativos valores de p < 0,05.

Resultados

Dos 928 doentes incluídos, completaram as três visitas 372. A adesão ao tratamento foi de 98,5%. Aos seis meses, apenas 20,8% dos doentes conheciam a doença e o único FR que melhorou foi o tabagismo (p= 0,04). A qualidade de vida diminuía em relação àpopulação em geral. O teste de elevação do tornozelo e a claudicometria mostraram uma correlação significativa (Pearson= 0,84).

Conclusões

Apesar da adesão ao tratamento ser muito elevado, a maioria de doentes com claudica-ção intermitente não têm um conhecimento preciso da sua doença. O controlo dos FR aos 6 meses de seguimento não é adequado.
