Avaliação dos efeitos a curto prazo de programas de conscientização e de terapia com pravastatina em indivíduos de alto risco para doença cardiovascular provenientes de consultórios particulares The evaluation of short term effects of awareness programs and pravastatin therapy on subjects from private clinics at high risk for cardiovascular disease
Abstract
OBJETIVO: Avaliar a eficácia de programas de conscientização (PC) sobre o controle de fatores de risco (FR) para doença cardiovascular (DCV). MÉTODOS: Pacientes hipercolesterolêmicos de alto risco para DCV foram divididos em 2 grupos durante 16 semanas. O grupo A (n=417, 54,3±10,0 anos, 55% homens) recebeu orientação verbal e escrita sobre controle de FR, e o grupo B (n=180, 54,4±10,9 anos, 45% homens) apenas orientação verbal. Todos os participantes receberam 10mg/dia de pravastatina por 12 semanas. Avaliaram-se o peso, pressão arterial, o colesterol total (CT) e frações, triglicérides, índices I e II de Castelli (CT/HDL-C e LDL-C/HDL-C) e escores de Framingham. RESULTADOS: No basal, A diferiu de B no HDL-C (40,0±11,0 vs 43,0±11,0mg/dl, p=0,013) e no índice I (8,2±3,0 vs 7,6±2,3, p=0,008). Após 16 semanas as variações % foram maiores em A do que B no CT (-28,0 vs -25,0, pPURPOSE: To evaluate short-term efficacy of awareness programs (AP) in reducing coronary heart disease risk factors (CHDRF). METHODS: High risk hypercholesterolemic patients were divided in 2 groups during 16 weeks. Group A (n=417, 54.3±10.0 years, 55% males) received verbal and written orientation on CHDRF control, and group B (n=180, 54.4±10.9 years, 45% males) received only verbal orientation. All participants received pravastatin 10mg q.d. for 12 weeks. The evolution of body weight, arterial pressure, lipid profile, Castelli's I and II indexes (TC/HDL and LDL/HDL), and Framingham scores were evaluated. RESULTS: At baseline, A had a lower HDL-C (40.0±11.0 vs 43.0±11.0mg/dl, p=0.013) and a higher index I (8.2±3.0 vs 7.6±2.3, p=0.008) than B. After 16 weeks, A had greater change than B in TC (-28.0 vs -25.0, p<0.05), LDL-C (-29.0 vs -27.6, p<0.05), HDL-C levels (+13.7 vs +10.8, p<0.05) and in the Castelli's Index (-39.0 vs -33.0; p<0.05). In both groups pravastatin use potentialized the effects of diet on the lipid profile. CONCLUSION: The AP seemed to be more effective than verbal orientation alone in CHDRF reduction at short-term.
