Heart failure patients with generalized edema, and a sudden rise in blood pressure is considered to be an acute attack of chronic right heart failure or chronic left heart failure with total heart failure, need for diuretic, cardiac, vasodilator, improve the prognosis of treatment. 1. Diuretic: diuretic furosemide intravenous injection, in addition to the diuretic effect, there is a venous dilatation effect, conducive to the rapid relief of pulmonary edema and generalized edema, the use of attention to the monitoring of ion levels. Diuretics are the cornerstone of heart failure treatment to improve symptoms, is the only drug that can control fluid retention in the treatment of heart failure , but can not be used as a single treatment. 2. Cardiotonic: increase myocardial contractility and cardiac output and are conducive to the improvement of symptoms, at the same time can reduce peripheral vascular resistance, increase renal blood flow, increase urinary excretion, increase coronary blood flow, improve myocardial ischemia. Commonly used drugs are small to medium doses of dopamine, milrinone, levosimendan and so on. 3. Vasodilatation: reduce peripheral resistance, can effectively lower blood pressure, reduce cardiac afterload, but also conducive to improve coronary blood supply, trial period must closely monitor blood pressure changes, small doses of slow drug delivery and combined with cardiotonic drugs. Commonly used drugs are sodium nitroprusside, isosorbide nitrate, human recombinant brain natriuretic peptide and so on. 4. Improve the prognosis, improve myocardial remodeling, significantly reduce the risk of heart failure hospitalization and cardiovascular death, improve symptoms and quality of life, commonly used drugs are dagliflozin, sakubutra valsartan, etc.. The emergence of an acute attack of heart failure, should immediately seek medical treatment, so as not to delay the condition of serious consequences.
