Abstract

We have previously reported that a long-acting loop diuretic, azosemide, reduces cardiovascular risks in patients with chronic heart failure (CHF) as compared with a short-acting one, furosemide, in Japanese Multicenter Evaluation of LOng- versus short-acting Diuretics In Congestive heart failure (J-MELODIC). However, the mechanisms of the difference have not been elucidated. This study aimed to examine whether there is a difference in the reduction in plasma brain natriuretic peptide (BNP) level and in left ventricular (LV) functional recovery between the CHF patients treated with the long-acting diuretic (the azosemide group) and the short-acting diuretic (the furosemide group). We reviewed changes in plasma BNP level and echo-assessed LV functional parameters from baseline to a year after the entry in 288 CHF patients with New York Heart Association class II or III symptoms that joined J-MELODIC. The decrease in plasma BNP levels was larger in the azosemide group than in the furosemide group (p < 0.01). The changes in echocardiographic parameters were not more favorable in the azosemide group than in the furosemide group. In conclusion, the decrease in plasma BNP levels was larger in the azosemide group than in the furosemide group. These findings may account for the better prognosis in CHF patients treated with azosemide than those with furosemide in J-MELODIC.
