[Effects of atorvastatin in N-terminal pro-brain natriuretic peptide plasma levels in hypercholesterolemic patients with or without hypertension]. / Efecto de la atorvastatina sobre los valores del propéptido natriurético cerebral N-terminal en pacientes con hipercolesterolemia con hipertensión arterial y sin ella.

ABSTRACT

BACKGROUND AND OBJECTIVE: N-terminal pro-brain natriuretic peptide (NT-proBNP) is a useful predictor of cardiovascular events in patients without clinical evidence of cardiovascular disease. It is unknown if the cardiovascular risk factors control can modify these levels. We studied if atorvastatin treatment decrease NT-proBNP levels in hypercholesterolemic subjects, with and without hypertension. PATIENTS AND METHOD: It was an open, prospective study in 39 patients with hypercholesterolemia without clinical evidence of cardiovascular disease. 15 (38.5%) had hypertension. Blood samples were collected initially and 12 and 24 weeks after beginning treatment with 20 mg of atorvastatin. RESULTS: The median age was 54 years, and 41% were males. NT-proBNP (pg/ml) values were 193 (294) at baseline; 141 (211) (p < 0.05) after 12 weeks therapy, and 89 (130) (p < 0.01) at 24 weeks. In hypertensive patients value changed from 275 (388) at baseline, 196 (290) (p < 0.05) and 112 (124) (p < 0.001) after 12 and 24 weeks treatment. And the levels in normotensives patients were 137 (198) at baseline, 103 (129) (p = NS), and 74 (135) (p < 0.001) at 12 and 24 weeks after treatment with atorvastatin. We didn't find any correlations between the percentage decrease in NT-proBNP levels, and change of total cholesterol, systolic blood pressure, C reactive protein, or nitrites/nitrates blood levels, at 12, and 24 weeks compared to baseline levels. CONCLUSIONS: In middle-aged hypercholesterolemic patients, without evidence of cardiovascular disease, atorvastatin therapy decrease NT-proBNP blood levels, in both hypertensive and normotensives subjects.
