What are the signs of insufficient blood supply to the heart?

Insufficient blood supply to the heart must be taken seriously, because the heart is the main organ that maintains our life activities. If the heart is not supplied with enough blood, it will easily lead to cardiac hypoxia or cause other adverse injuries. We should also understand the symptoms of insufficient blood supply to the heart. If you find weakness in your limbs, swollen legs, or dizziness, memory loss, and accompanied by cardiovascular diseases, they may be caused by insufficient blood supply to the heart.

1. Weak limbs, swollen feet, insufficient blood flow to the legs, frequent leg soreness, leg swelling or leg pain; if it is the hands or arms, the hands may be weak or even difficult to lift things. In addition, cardiogenic edema is closely related to insufficient blood flow dynamics, which can easily cause edema in sagging parts such as ankles and calves.

2. Dizziness, blurred vision and memory loss . When blood flow is insufficient, the brain tissue is not supplied with enough blood, causing cerebral ischemia and hypoxia. Symptoms include dizziness, general weakness, unsteady walking, and a significant loss of memory, which affects work and study efficiency and may even lead to fainting or cerebral infarction.

3. Cardiovascular disease The heart is the "engine" of the human body. If the heart is not supplied with enough blood, it is easy to cause cardiovascular diseases such as heart failure. Data from the 2015 "Blue Book on the Current Status of Cardiovascular Disease Prevention and Treatment in China" jointly released by the Chinese Medical Association and the Vascular Disease Branch of the Chinese Medical Association showed that the number of cardiovascular disease patients in my country has reached 290 million, ranking first in the incidence and mortality of all diseases in my country.

4. Pulmonary congestion Due to reduced cardiac output and obstructed venous return, congestion may also form in the lungs. Patients often experience breathing difficulties and hypoxia, and cough up pink foamy sputum. Long-term conditions can cause the alveolar walls to thicken and fibrose, become hard in texture, and appear brown to the naked eye, which is called brown lung lesions.
