The presence of low blood pressure in patients with heart failure is often a sign of more severe disease and a poor prognosis.
Normal arterial blood pressure is formed by a combination of cardiac systolic ejection, adequate blood volume, peripheral resistance, and the elastic reservoir action of the middle and large arteries, and low blood pressure occurs if the heart failure condition is severe.
Heart failure is a group of clinical syndromes due to the inability of cardiac ejection to meet the needs of the tissues and organs in the peripheral circulation, which is mainly manifested as shortness of breath, chest tightness, palpitations, edema, fatigue, and decreased exercise tolerance.
In the early stage of heart failure disease, due to various compensatory mechanisms such as neurological and humoral, blood pressure is often not lowered, and patients can have no obvious clinical manifestations in the stabilization period. Hypotension occurs when heart failure patients’ myocardial contractility decreases significantly, which is a manifestation of heart failure patients’ disease loss of compensation and poor prognosis.
When patients with heart failure have hypotension, they should consult a doctor in time and follow the doctor’s instructions to standardize the treatment.
