RESUMO

OBJETIVO:

Determinar a prevalência de estenose da artéria renal (EAR) em pacientes submetidos a cineangiocoronariografia.

MÉTODOS:

Estudo prospectivo, considerando 1.656 cinean-giocoronariografias seguidas de aortografia, entre janeiro/2002 e fevereiro/2004, de pacientes encaminhados à cineangiocoronariografia diagnóstica com história ou não de hipertensão arterial sistêmica (HAS).

RESULTADOS:

Dos 1.656 pacientes, a idade média foi de 61,6 ± 11,8 anos, 53,8 por cento eram do sexo masculino, 10,2 por cento eram diabéticos, 63,8 por cento apresentavam coronariopatia obstrutiva. A presença de EAR maior que 50 por cento foi observada em 228 (13,8 por cento) pacientes, e em 25 (1,5 por cento) destes, ocorreu bilateralmente. A coronariopatia obstrutiva foi definida como estenose que causa redução do lúmen do vaso em 50 por cento ou mais, em um, dois ou três vasos principais, denominados uniarterial, biarterial ou triarterial, respectivamente.A quantificação era realizada através da análise visual da angiografia. Comparando os grupos com e sem EAR > 50 por cento, observou-se diferença estatisticamente significativa quanto a gênero, idade, ocorrência de diabete melito, PA e função ventricular esquerda. Não houve diferença significativa, no entanto, quanto à ocorrência de obstrução coronariana > 50 por cento. Quando, porém, a EAR considerada é > 70 por cento, observa-se diferença significativa quanto a PA, associação à obstrução coronariana > 50 por cento e à disfunção ventricular esquerda, maiores no grupo com EAR.

CONCLUSÃO:

A prevalência de EAR neste estudo foi comparável àquela das grandes casuísticas da literatura e, em razão de sua importância pela associação com HAS e doença renal terminal (DRT) e suas seqüelas, devemos estar atentos para seu diagnóstico angiográfico.
ABSTRACT

OBJECTIVE:

To determine the prevalence of renal artery stenosis (RAS) in patients who have undergone cineangiocoronariography.

METHODS:

Prospective study of cineangiocoronariography and aortography examinations conducted between January 2002 and February 2004 on 1,656 hypertensive and normotensive patients who underwent the examinations to confirm the diagnosis of obstructive coronary artery disease or valve disease.

RESULTS:

The average age of the 1,656 patients was 61.6 ± 11.8 years. Eight hundred and ninety-one (53.8 percent) were male, 169 (10.2 percent) were diabetic and 1,054 (63.8 percent) presented obstructive coronary artery disease. Renal stenosis greater than 50 percent was observed in 228 (13.8 percent) patients, and 25 (1.5 percent) had bilateral stenosis. Obstructive coronary artery disease was defined as stenosis greater than or equal to 50 percent of the vessel lumen, in one, two or three main arteries, classified as single, double or triple vessels, respectively. Quantification was conducted using visual analysis of the angiography. Comparison of the groups with and without renal artery obstruction > 50 percent, revealed significant statistical differences in relation to gender, age, diabetes mellitus, blood pressure and left ventricular function. However, no statistical difference was noted in relation to the occurrence of coronary artery obstructions > 50 percent. Nevertheless, renal artery obstructions > 70 percent, revealed significant differences in relation to blood pressure, coronary artery obstructions > 50 percent and left ventricular function, which were all higher in the renal artery obstruction group.

CONCLUSION:

The prevalence of RAS found in our study was comparable to that reported by major medical literature case studies. RAS is associated with systemic hypertension (SH), end-stage renal disease (ESRD) and its sequelae, emphasizing how important it is that we are aware of possible candidates for angiographic diagnosis of this disease.
