How low is blood pressure dangerously low in heart failure patients?

Heart failure patients with blood pressure below 90/60mmHg is relatively dangerous and may affect vital organs such as further damage to heart function, insufficient blood supply to the brain, renal ischemia and so on.
1. Further impairment of heart function: If the blood pressure is lower than 90/60mmHg in heart failure, it may lead to insufficient blood supply to the coronary arteries, further damage to the myocardium, and a decline in cardiac function, which may eventually lead to serious impairment of heart function if not diagnosed and treated in a timely manner.
2. Insufficient blood supply to the brain: if the blood pressure of heart failure is lower than 90/60mmHg, it will lead to insufficient blood supply to the brain, which may lead to blackout or even fainting, and if the blood supply to the brain is insufficient for a long time, it will also lead to irreversible damage to the brain cells.
3. Renal ischemia: If the blood pressure of heart failure patients is lower than 90/60mmHg, it may lead to insufficient blood supply to the kidneys, and a large number of metabolic toxins can not be normally discharged through the kidneys, leading to accumulation of toxins in the body, which may lead to acute or chronic renal insufficiency.
It can be seen that heart failure patients with blood pressure below 90/60mmHg, the impact on vital organs is still very large, is relatively dangerous, so for the heart function is not good for the crowd, should be timely monitoring of blood pressure, and when there are symptoms of discomfort, should be timely medical care.
