The Efficacy of Different Therapy Protocols for Heart Failure in Patients with Heart Failure and Increased Natriuretic Peptide Level

The Efficacy of Different Therapy Protocols for Heart Failure in Patients with Heart Failure and Increased Natriuretic Peptide Level Natriuretic peptide BNP might be clinically useful for monitoring treatment effects in patients with heart failure (HF). In order to investigate the pharmacological effects of different therapy protocols for patients with HF based on the BNP level before and after therapy, we performed an open randomized comparative trial. Sixty-two HF patients with increased natriuretic peptide level, aged 55.82±9.09, II-III NYHA functional classes, ejection fraction (EF) <45%, received a 12-week treatment with either traditional pharmacotherapy for HF with ACE inhibitors and β-blockers (1 st group), or ACE inhibitors and angiotensin II receptor blockers (ARBs) (2 nd group), or β-blockers and ARBs (3 rd group), and ACE inhibitors, β-blockers and ARBs (4 th group). We evaluated the BNP plasma level, hemodynamic state (pulmonary capillary wedge pressure (PCWP), cardiac output (CO), EF and exercise capacity. The BNP plasma level decreased significantly in the 4 th group of patients who received ACE inhibitors, β-blockers and ARBs, in comparison to other groups. A beneficial influence on hemodynamic and exercise capacity was significantly pronounced in this group, compared to the other therapy regimes. In conclusion, the therapeutic protocol: ACE inhibitors, β-blockers and ARBs in HF patients with increased natriuretic peptide level significantly improves the quality of life, left ventricular function, hemodynamic parameters and exercise capacity. All these changes were accompanied with a decreasing of the BNP plasma level.
