The blood pressure of patients with heart failure should be controlled within the normal range, <140/90mmHg is better, but should not be too low, so as not to cause insufficient perfusion of important organs. Patients with heart failure should control their blood pressure level within the normal range, below 140/90mmHg, preferably <130/80mmHg, but the specific blood pressure level should be formulated according to the patient's condition. However, care should be taken to avoid the blood pressure level being too low, so as not to aggravate the condition by insufficient perfusion of vital organs. For patients with heart failure combined with hypertension, it is important to control the blood pressure level to within the normal range, which can effectively reduce the cardiac afterload. However, some patients with heart failure may have relatively low blood pressure levels, related to the decline in myocardial contractility, and should strive to keep their blood pressure levels above 90/60 mmHg. Blood pressure levels vary significantly from one heart failure patient to another, and it is important to maintain appropriate blood pressure levels under the direction of a physician.
