Abstract:
Objective To investigate the effect of spirolactone on cardiac function and serum brain natriuretic peptide in patients with chronic heart failure( CHF). Methods Eighty-four patients with CHF were randomly divided into control group( n=42 )and observation group( n=42 ). The patients in the control group were given conventional therapy,while in the observation group were given spirolactone( 20 mg/times,2 times/day)based on treatment of the control group for six months. The clinical effects and left ventricular end diastolic diameter( LVEDd ),left ventricular ejection fraction( LVEF ) and serum brain natriuretic peptide( BNP ) of pretherapy and post-treatment between the two groups were recorded and compared. Results The total effective rate of observation group was 95. 2%(40/42),obviously higher than that of control group(80. 9%(34/42),χ2=6. 468,P=0. 028). The levels of LVEDd and BNP in two groups after treatment were(57. 8 ± 6. 2)mm and (62. 4 ± 7. 8)mm,(364. 4 ± 32. 8)ng/L and(457. 4 ± 43. 2)ng/L,significantly lower than those at before treatment((64. 6 ± 7. 4)mm and(64. 8 ± 7. 6)mm,(867. 8 ± 78. 5)ng/L and(864. 4 ± 74. 8)ng/L),while LVEF in two groups after treatment were( 49. 8 ± 5. 4 )% and( 42. 6 ± 4. 6 )%,significantly higher than those before treatment((35. 2 ± 3. 9)% and(35. 4 ± 3. 5)%),and the differences were significant(t = -3. 264, 4. 626,-5. 373,-3. 932,5. 438,-6. 548;P﹤0. 05). Moreover the changes in observation group were obvious than those in control group in terms of LVEDd,BNP and LVEF( t = -3. 425,3. 644,-2. 846;P ﹤0. 05 ) . Conclusion Spironolactone can effectively decrease the serum brain natriuretic peptide levels,improve the cardiac function in patients with chronic heart failure,and it is worthy of popularization and application.
