| Abstract: | Introduction: The dyslipidemia is one of the main factors of risk of coronary artery disease that contributes for the risk of cardiovascular diseases, but around one third of the patients with acute myocardial infarctions. Have normal levels of total and LDLC cholesterol. There is few data of the lipid profile and the Non HDL cholesterol (non-HDL-C) in patients with non-ST-segment elevation acute coronary syndrome (SCASSST).Objective: Analyze the lipid profile of patients with SCASSST/Unstable Angina and IAM with no ST-segment elevation (IAMSSST), including the determination of non- HDL-C. Methods: Observational Transversal. Study analyzed data of 1080 admitted patients with Acute Coronary Syndrome (IA/IAMSSST at the cardiovascular Intensive care unit at PUCRS-São Lucas Hospital between the period of September/1999 and October/2010. Analysis of the lipid profile were realized in the first 24h of the admission. Results: Among the 1080 patients, 51,9% male, 32,9% diabetics, 84,1% presented systemic arterial hypertension,26,1 smokers. In the analyzed sample it was observed that 53,4% of the patients had been using hypolipidemic treatment. At the lipid profile it was observed that 44,8% of patients presented abnormal levels of Triglycerides, 66,6% (men) and 73,3 (women) HDL-C out of goals; 30,2% of patients presented total cholesterol >200mg/dL, and 24,4% had LDL-C >130mg/dl and 51,7% LDL-C >100mg/dL. Among the 1080 patients 182 had triglycerides >200mg/dL associated to LDL-C > 130mg/dL of which, 58 patients (31,9%) presented non-HDL-C >160mg/dL. Conclusion: The results of our study demonstrate that the majority of patients with SCA (AI/IAMSSST) had low HDL-C and about half of them presented LDL-C <100mg/dL. The non-HDL-C had been elevated in one third of the patients, associated to elevated triglycerides levels.
Introdução: A dislipidemia é um dos principais fatores de risco para a doença arterial coronariana, porém cerca de um terço dos pacientes com infarto agudo do miocárdio estão com níveis de colesterol total e LDL-C normais. Há poucos dados do perfil lipídico e do não-HDL-colesterol (não-HDL-C), em pacientes com síndrome coronariana aguda sem supradesnivelamento de ST (SCASSST).Objetivo: Analisar o perfil lipídico de pacientes com SCASSST/Angina Instável e IAM sem supradesnivelamento de ST (IAMSSST), incluindo-se a determinação do não-HDL-C.Métodos: Estudo observacional transversal analisou 1080 pacientes internados com Síndrome Coronariana Aguda (AI/IAMSSST) na Unidade de Terapia Intensiva Cardiovascular do Hospital São Lucas-PUCRS, entre setembro/1999 a outubro/2010. Foram realizadas análises do perfil lipídico nas primeiras 24h da admissão. Resultados: Entre os 1080 pacientes, 51,9% do sexo masculino, 32,9% diabéticos, 84,1% apresentavam hipertensão arterial sistêmica e 26,1% tabagistas. Na amostra analisada, observou-se que 53,4% dos pacientes faziam o uso de tratamento hipolipemiante. Na análise do perfil lipídico observou-se: 44,8% apresentaram níveis de triglicerídeos anormais; 66,6% (homens) e 73,3% (mulheres) HDL-C fora das metas; 30,2% dos pacientes apresentavam colesterol total >200mg/dL, sendo que 24,4% tinham LDL-C >130mg/dL e 51,7% LDL-C >100mg/dL. Entre os 1080 pacientes, 182 tinham triglicerídeos >200mg/dL associado a LDL-C > 130mg/dL; destes, 58 pacientes (31,9%) apresentavam não-HDL-C >160mg/dL. Conclusão: Os resultados do nosso estudo demonstram que a maioria dos pacientes com SCA (AI/IAMSSST) tinham HDL-C baixo e cerca de metade apresentavam LDL-C <100mg/dL. O não-HDL-C esteve elevado em um terço dos pacientes associado a níveis elevados de triglicerídeos. |
