Understand Your Risk for Excessive Blood Clotting
Many factors can lead to excessive blood clotting, leading to limited or blocked blood flow. Blood clots can travel to the arteries or veins in the brain, 心, 肾脏, 肺和四肢, 这会导致 心脏病, 中风器官损伤甚至死亡.
获得性危险因素
- 超重和 肥胖
- 先进的时代
- 怀孕
- Prolonged bed rest due to surgery, hospitalization or illness
- Long periods of sitting, such as car or plane trips
- Use of birth control pills or hormone replacement therapy
- 癌症
- 吸烟
- 糖尿病
- 炎症
- Antiphospholipid syndrome (an autoimmune disorder)
- Dehydration may cause blood vessels to narrow and blood to thicken, raising the risk of blood clots.
遗传风险因素
的基因, 或者继承, source of excessive blood clotting is less common and is usually due to genetic defects. These defects often occur in the proteins needed for blood clotting and can also occur with the substances that delay or dissolve blood clots.
You are more likely to have a genetic cause of excessive blood clotting if you have:
- Family members who have had dangerous blood clots.
- A personal history of repeated blood clots before age 40.
- A personal history of unexplained miscarriages.
Other risk factors – diseases and conditions
Many diseases and conditions can cause excessive blood clotting. Certain diseases and conditions are more likely to cause clots to form in specific areas of the body.
Conditions that can trigger excessive blood clotting in the 心 and brain:
- 血管炎 is a disorder that causes the body's blood vessels to become inflamed. Platelets may stick to areas where the blood vessels are damaged and form clots.
- 糖尿病 increases the risk of plaque buildup in the arteries, 这会导致 dangerous blood clots.
- 心脏衰竭 is a condition in which the 心 is damaged or weakened. When the 心 can't pump enough blood to meet the body's needs, blood flow slows 这会导致 clots to form.
- 心房纤颤 最常见的类型是 心律失常或心律不齐. 心房纤颤 can cause blood to pool in the upper chambers of the 心 and can cause clots to form.
- 超重和肥胖 refer to body weight that's greater than what is considered healthy. These conditions can lead to inflammation and damage the lining of the blood vessels.
- 代谢综合征 is the name for a group of risk factors that increases your chance of having 心 disease and other health problems, including an increased risk of forming blood clots.
Conditions that can trigger excessive blood clotting in the limbs include:
- 深静脉血栓(DVT) is a condition where blood clots form in the veins deep in the limbs. A blood clot in a deep vein can break off and travel through the bloodstream. If the clot travels to the lungs and blocks blood flow, the condition is called pulmonary embolism.
- 外周动脉疾病 (PAD) is a narrowing of the peripheral arteries, most commonly in the arteries of the pelvis and legs. PAD is similar to coronary artery disease and carotid artery disease. All three of these conditions are caused by narrowed and blocked arteries in various critical regions of the body. Hardened arteries (or atherosclerosis) in the coronary artery region, restricts the blood supply to the 心 muscle. (View an illustration of coronary arteries.) Carotid artery disease refers to atherosclerosis in the arteries that supply blood to the brain.
- 动脉粥样硬化: 是哪一种疾病中的斑块(脂肪), cholesterol and other deposits) builds up in the wall of an artery. Plaque formations can grow large enough to greatly reduce the blood flow through an artery. When a plaque formation becomes brittle or inflamed, it may rupture, causing a blood clot to form. A clot may further narrow the artery or completely block it.
