There is no so-called optimal treatment for left heart failure, and the conventional comprehensive treatment includes general treatment, drug treatment and treatment in the acute stage.
1. General treatment: low-salt diet is recommended, physical activity should be restricted and bed rest should be paid attention to during acute onset of the disease.
2. Drug therapy: common drugs include diuretics, angiotensin-converting enzyme inhibitors, β-receptor antagonists and positive inotropic agents.
(1) Diuretics: mostly used for obvious fluid retention, commonly used drugs such as hydrochlorothiazide, with adverse effects such as hyperuricemia.
(2) Angiotensin-converting enzyme inhibitors or angiotensin receptor antagonists: can relieve the symptoms, but also slow down the progress of heart failure. Such as perindopril or irbesartan, etc. Adverse effects include hypotension and dry cough. The newest drug, sacubitril valsartan, is also available for treatment.
(3) β-receptor antagonists: common drugs used are metoprolol, etc., which are prohibited in patients with bronchospasm.
(4) Positive inotropic drugs: commonly used drugs for digoxin, etc., adverse reactions have all kinds of arrhythmia.
3. Treatment of acute stage: improve symptoms and stabilize hemodynamic status.
