pharmacologic intervention in CHF
抗心衰药物是主要用于治疗CHF的药物,主要有强心苷、非甙类正性肌力药、利尿药、ACEI和β受体阻断药等。
Improving hemodynamics with inotropic drugs does not decrease mortality; (病马加鞭)
long-term treatment directed towards neurohormonal factors with ACE inhibitors and beta-blockers can decrease mortality

Consensus recommendations for the management of CHF
Patients with heart failure should first be evaluated to assess LV ejection fraction. Patients with systolic dysfunction (EF <40%) should then undergo the following treatment:
水钠潴留:利尿药
ACEIs,ARBs 和/或 beta-blocker
室率快的房颤:强心苷(地高辛)
重症患者延长寿命:醛固酮受体拮抗剂

fluid retention - a diuretic.
ACE inhibitor and beta-blocker should be initiated and maintained unless specifically contraindicated. (Patients with severe heart failure should probably not receive a beta-blocker)
Digoxin - in patients with rapid atrial fibrillation.
Spironolactone, an aldosterone antagonist, may reduce mortality in patients with severe heart failure
第十五页,共34页。
ACE inhibitors
first-line therapy in all patients with heart failure
improve symptoms, slow progression of the disease, reduce mortality, and decrease the incidence of hospitalization
The most common adverse effects of ACE inhibitors are directly related to lowering angiotensin II concentrations (hypotension and renal insufficiency) and increasing concentrations of kinins (cough and angioneurotic edema)
