RESUMO
FUNDAMENTO A associação do índice tornozelo-braquial (ITB) com a medida do complexo médio intimal das artérias carótidas (MCMI) não está amplamente estudada.

OBJETIVO:

Objetivamos avaliar se pacientes com ITB < 0,9 apresentam maior prevalência de placa aterosclerótica carotídea do que aqueles com ITB > 0,9.

MÉTODOS:

No período de janeiro a dezembro de 2011, recrutamos 118 pacientes (48 homens e 70 mulheres) que tiveram seus ITB e MCMI mensurados. Os pacientes foram divididos em grupo 1 (ITB < 0,9) e grupo 2 (ITB > 0,9). Utilizamos os testes de Mann-Whitney, qui-quadrado e Fischer para comparações entre os grupos. Para avaliar correlação entre ITB e MCMI empregamos a correlação de Pearson.

RESULTADOS:

A prevalência de ITB < 0,9 foi 29,7%, enquanto a da MCMI > 1,5 mm de 34,7%. Não houve diferença de características clínicas entre os grupos 1 e 2 idade média (64 ± 9 vs. 62 ± 7,2 anos, p = 0,1), homens (40% vs. 41%, p = 0,9), hipertensão (74% vs. 59%, p = 0,1), diabetes melito (54% vs. 35%, p = 0,051), dislipidemia 26% vs. 24%, p = 0,8), tabagismo (57% vs. 65%, p = 0,4). A prevalência de placa carotídea foi maior no grupo 1 (48,6% vs. 28,9%, p = 0,04). A correlação de Pearson entre o ITB e a MCMI foi de - 0,235, com valor de p = 0,01.

CONCLUSÕES:

Pacientes com ITB < 0,9 apresentaram maior prevalência de aterosclerose carotídea. Houve correlação negativa entre o ITB e a MCMI.
ABSTRACT

BACKGROUND:

The association between the ankle brachial index (ABI) and the measurement of intimal medial thickness (IMT) has not been fully studied.

OBJECTIVE:

We aimed to evaluate whether the prevalence of carotid atherosclerosis was higher in patients with ABI < 0.9 than in those with ABI > 0.9.

METHODS:

From January 2011 to December 2011, 118 patients (48 men and 70 women) were enrolled. ABI and IMT Measurements were performed in all patients. Patients were divided in Group 1 (ABI < 0.9) and Group 2 (ABI > 0.9) according to ABI values. Mann-Whitney, Chi-square and Fischer tests were used for comparison among the groups. Pearson's correlation was used to assess correlation between ABI and IMT.

RESULTS:

The prevalence of ABI < 0.9 was 29.7%, whereas carotid atherosclerosis > 1.5 mm was 34.7 %. Clinical characteristics were similar between groups 1 and 2 mean age (64 ± 9 vs. 62 ± 7.2 years, p = 0.1), male gender (40% vs. 41%, p = 0.9), hypertension (74% vs. 59%, p = 0.1), diabetes mellitus (54% vs. 35%, p = 0.051), dyslipidemia (26% vs. 24%, p = 0.8), smoking (57% vs. 65%, p = 0.4). The prevalence of carotid atherosclerosis was higher in group 1 (48.6% vs. 28.9%, p = 0.04). Pearson's correlation between ABI and IMT was -0.235, with a p value = 0.01.

CONCLUSION:

Patients with ABI < 0.9 showed a higher prevalence of carotid atherosclerosis. There was a negative correlation between ABI and IMT.
