RESUMO

Objetivos:

Avaliar a prevalência de diabetes mellitus buscando associação com a gravidade da doença arterial coronária em pacientes submetidos à intervenção coronária percutânea em centro de referência no sul do Brasil.

Métodos:

Estudo transversal. Foram avaliados todos os pacientes submetidos à intervenção coronária percutânea eletiva entre novembro/2006 e dezembro/2007 em hospital de referência. Aplicou-se questionário previamente ao procedimento e realizou-se glicemia capilar em jejum.

Resultados:

Foram realizadas 617 intervenções coronárias percutâneas e implantados 718 stents em 569 indivíduos (1,32 stents por intervenção).Destes, 177 pacientes (32,2%) foram considerados diabéticos. Característicasdemográficas, fatores de risco para doença arterial coronária, vaso alvo, diâmetro do vaso e extensão da lesão foram semelhantes entre os grupos. Doença arterial coronária grave, categorias III e IV, foi encontrada em 51,2% dos pacientes com diabetes, comparados com 37,6% dos sem diabetes (p<0,001). Houve correlação significativa entre os níveis de glicemia e a gravidade da doença arterial coronária(p<0,05).

Conclusões:

Existe associação entre a presença de diabetes e a gravidade angiográfica da doença arterial coronária em pacientes submetidos à intervenção coronária percutânea, o que sugere que essa maior gravidade possa contribuir para os desfechos adversos nesses pacientes.
ABSTRACT

Aim:

To evaluate the prevalence of diabetes mellitus by searching for an association between severe coronary artery disease (CAD) in patients undergoing percutaneous coronary intervention (PCI) in a reference center in southern Brazil.

Methods:

This was a cross-sectional study. Data were derived from patients undergoing PCI from November, 2006 to December, 2007 in a Brazilian reference center. A questionnaire was administered as well as a capillary blood glucose test before the procedure.

Results:

In all, 617 PCIs were performed with 718 stents implanted in 569 patients (1.32 stent/PCI).Diabetes was present in 177 patients (32%). Baseline demographics and angiographic characteristics(including CAD risk factors, target-vessels, vessel diameters, and lesion extensions) were similar between the two groups. Severe CAD (levels III and IV) was found in 51.2% of diabetic patients as compared to 37.6% of non-diabetic patients (p<0.001). Coronary artery disease was significantly less severe in non-diabetic subjects as compared to diabetic patients, with the presence of 1-vessel disease respectively in 38.5 vs. 27.9% (p<0.001). There was a significant correlation between bloodglucose levels and CAD severity (p<0.05).

Conclusion:

There is a significant correlation between the presence of diabetes and the severity of CAD in patients submitted for PCI, thereby suggesting that this more intense atherosclerotic process might contribute to the adverse cardiovascular events seen in diabetic patients.
