Symptoms of coronary artery stenosis

summary

Arterial embolism, known as arteriosclerotic occlusive disease, is a systemic disease occurring in the large and middle arteries of the whole body. The pathogenesis is that blood clots or foreign bodies entering the blood vessels block the blood vessels and form emboli in the blood vessels. With the blood flow, it stops in the artery whose diameter is equal to the size of the embolus, resulting in the blockage of the artery and causing acute ischemia. The severity of the disease is closely related to the speed of disease progression and the number of collateral circulation. The most common cases of this disease are distal abdominal aorta and iliofemoral popliteal artery embolism. Generally seen in male patients, the incidence of more than 45 years old.

Symptoms of coronary artery stenosis

The etiology and pathogenesis of the disease is not clear, the etiology may be smoking, caused by nicotine vasoconstriction. Cold stimulation by cold makes blood vessels spasm, causing embolism. Long term hormone level disorder, resulting in vasomotor dysfunction. Recent studies have shown that the history of vascular trauma can also cause arterial embolism, because the blood stasis in the blood vessel makes the diameter of the blood vessel decrease, resulting in thrombosis.

Because of the embolism and spasm of the artery, the pulsation of the artery far away from the embolism plane was weakened or even disappeared; The pulsation of the embolized proximal artery increased. This is how the pulse of the artery weakens or disappears. Sensory and motor disorders are caused by peripheral nerve ischemia, resulting in paresthesia, numbness and even loss of sensation of the skin on the distal limb of the lesion plane. Then it developed into deep sensory loss, with acupuncture like sensation, muscle weakness, even paralysis, and varying degrees of foot or wrist ptosis.

The general manifestations of arterial embolism are pain, changes of skin color and temperature, weakening or disappearance of arterial pulsation, sensory and motor disturbance, etc. Pain is the earliest symptom of the disease. Severe pain can be caused by spasm of the diseased artery and sudden increase of proximal arterial pressure. Because of the blockage of blood vessels, the disorder of blood circulation causes the change of skin color and the rise of temperature.

matters needing attention

The treatment of the disease can be surgical or non-surgical treatment, non-surgical method can reduce blood pressure and blood lipid, reduce the hypercoagulable state of blood, forming lateral limb circulation. However, artificial blood vessels can be implanted to bypass the diseased vessels.
