Elevated brain natriuretic peptide is commonly seen in chronic heart failure, and treatment includes general therapy and drug therapy. 1. General treatment: treat all underlying diseases that can lead to impaired cardiac function, such as hypertension, give tilmisartan, nifedipine and other antihypertensive treatment; coronary artery disease, give aspirin, atorvastatin and other antiplatelet aggregation, plaque stabilization treatment; lung infection, give cefuroxime and other anti-infective treatment. 2.Drug treatment (1) Diuretics: such as furosemide, hydrochlorothiazide, etc. to diuretic edema and reduce the heart load. (2) Angiotensin-converting enzyme inhibitors: such as Benadryl can reduce the adverse effects of neurohumoral compensatory mechanisms in patients with heart failure, improve ventricular remodeling, adverse effects such as dry cough, angioedema, can be changed to angiotensin receptor antagonists. (3) Positive inotropic drugs: such as digoxin to enhance myocardial contractility. (4) Vasodilator drugs: e.g. nitroglycerin is not routinely used, and is used in combination when hypertension and angina pectoris are present. When brain natriuretic peptide is elevated, it is recommended to go to the cardiology department of the hospital and be treated under the doctor’s treatment.
