99% of blood clots have no symptoms.

Thrombotic diseases include arterial thrombosis and venous thrombosis. Arterial thrombosis is relatively more common, but venous thrombosis was once considered a rare disease and has not been paid enough attention.

 

1. Arterial thrombosis: the root cause of myocardial infarction and cerebral infarction

The most familiar source of myocardial infarction and cerebral infarction is arterial thrombosis.

At present, among the national cardiovascular diseases, hemorrhagic stroke has declined, but the morbidity and mortality of coronary heart disease are still rising rapidly, and the most obvious one is myocardial infarction! Cerebral infarction, like myocardial infarction, is known for its high morbidity, high disability, high recurrence and high mortality!

 

2. Venous thrombosis: "invisible killer", asymptomatic

Thrombosis is the common pathogenesis of myocardial infarction, stroke and venous thromboembolism, the top three fatal cardiovascular diseases in the world.

The severity of the first two is believed to be known to everyone. Although venous thromboembolism ranks the third largest cardiovascular killer, unfortunately, the public awareness rate is very low.

Venous thrombosis is known as the "invisible killer". The scary thing is that most venous thrombosis do not have any symptoms.

 

There are three main factors for venous thrombosis: slow blood flow, venous wall damage, and blood hypercoagulability.

Patients with varicose veins, patients with high blood sugar, high blood pressure, dyslipidemia, patients with infection, people who sit and stand for a long time, and pregnant women are all high-risk groups of venous thrombosis.

After the occurrence of venous thrombosis, symptoms such as redness, swelling, stiffness, nodules, cramping pain and other symptoms of the veins appear in mild cases.

 

In severe cases, deep phlebitis develops, and the patient's skin develops brown erythema, followed by purple-dark redness, ulceration, muscle atrophy and necrosis, fever all over the body, severe pain in the patient, and may eventually face amputation.

If the blood clot travels to the lungs, blocking the pulmonary artery can cause a pulmonary embolism, which can be life-threatening.
