Low blood pressure in heart failure is related to heart pump failure as well as application of drugs.
1. Heart pump failure: heart failure is a clinical syndrome of tissue and organ insufficiency caused by heart pump failure. Heart failure patients with diastolic and contractile function of the heart muscle decline, in the early stage of heart failure, the heart has a certain compensatory function, the blood pressure may be maintained at normal levels, but as the disease progresses, the heart function enters a period of failure to compensate for the situation, there will be low blood pressure.
2. Application of drugs: patients with heart failure often apply diuretics such as spironolactone, β-blocker propranolol, angiotensin-converting enzyme inhibitors / angiotensin II receptor blockers such as captopril and valsartan, etc., angiotensin receptor enkephalinase inhibitors such as sarcoplasmic reticulocysteine valsartan, all of these drugs will affect the blood pressure, the occurrence of low blood pressure.
Low blood pressure in heart failure, can be appropriate application of blood pressure-raising drugs such as small doses of dopamine with cardiac drugs such as sildenafil.
Heart failure belongs to the end stage of various heart diseases, as well as a more complex clinical syndrome, with a higher incidence and a poorer prognosis. Approximately 15-25% of patients with heart failure have low blood pressure, and prompt and effective treatment should be implemented for patients with heart failure combined with low blood pressure. If low blood pressure occurs, seek medical attention and follow your doctor’s instructions.
