Hypertension has turned out to be one of the main causes of heart failure, and hypertension combined with heart failure is more common. At this time, the use of drugs that can lower blood pressure and improve prognosis is required, so the drug of choice is the ACEI class of drugs, that is, the Prilosec class of drugs. When these drugs are not tolerated, the ARB alternative is used, i.e. sartan or other drugs. It can both lower blood pressure and improve the prognosis of heart failure patients, so it is often the first choice as an antihypertensive drug. Another drug is beta-blockers, which can lower blood pressure on the one hand and improve the prognosis of heart failure patients on the other. However, there is a timing problem with the use of beta-blockers for heart failure patients. When acute left heart failure patients are in the acute phase, beta-blockers cannot be used when the hemodynamics are not stable enough, and there are also contraindications when the blood pressure is in cardiogenic shock, and this drug should be used according to the condition.
