What causes blood clots? Blood clots are essential to stop bleeding after injury, but harmful blood clots can also form, causing serious damage. Most heart attacks and strokes result from the sudden formation of a blood clot on a cholesterol plaque inside an artery in the heart or brain. When the plaque ruptures suddenly, thrombogenic substances inside the plaque are exposed to blood, triggering the blood clotting process.

Blood Clots and Ways of Prevent it There is a complex mechanism in place to form clots in the blood. Clots form when there is damage to the blood vessels and an initial clot is formed. There is a sort of cascade effect when the blood is clotting inappropriately. Fibrin is formed which causes the clot to become intense and life threatening especially if it is deep in the vein or breaks free and travels to the lungs.

- 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, heart, kidneys, lungs and limbs, which in turn can cause heart attack, stroke, damage to the body’s organs or even death. 1  Smoking.

Causes Blood clots form when platelets (blood components) and plasma proteins thicken, forming a semisolid mass. This process may be triggered by an injury or it can sometimes occur inside blood vessels that don't have an obvious injury. Once these clots form, they can travel to other parts of your body, causing harm.

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, heart, kidneys, lungs and limbs, which in turn can cause heart attack, stroke, damage to the body’s organs or even death. The genetic, or inherited, source of excessive blood clotting is less common and is usually due to genetic defects.

Blood Clots Normally, if you get hurt, your body forms a blood clot to stop the bleeding. Some people get too many clots or their blood clots abnormally. Many conditions can cause the blood to clot too much or prevent blood clots from dissolving properly. Blood clots can form in, or travel to, the blood vessels in the brain, heart, kidneys, lungs, and limbs. A clot in the veins deep in the limbs is called deep vein thrombosis (DVT). DVT usually affects the deep veins of the legs.

Blood Clots When a blood clot (thrombus) forms in one or more arteries that supply blood to the heart, it blocks the blood flow to a part of the heart muscle, reducing or completely cutting off the oxygen supply to the cells in that area. 1  As a result, the part of the heart muscle that is deprived of oxygen dies, and a heart attack occurs.

Blood Clots Blood clotting problems and rare blood disorders also cause blood clots to form, but the cause of blood clots is not always known. For some women, the use of oral contraceptives (birth control pills) may increase the risk of blood clot formation. The risk is higher for women over 35 years of age who smoke or have a history of previous blood clots. A variety of things can cause inflammation of a superficial vein. One common cause is due to trauma or injury, for example from solutions or medications given intravenously (into a vein) in hospitals.

- Pulmonary embolism is caused by a blocked artery in the lungs. The most common cause of such a blockage is a blood clot that forms in a deep vein in the leg and travels to the lungs, where it becomes lodged in a smaller lung artery. Almost all blood clots that cause pulmonary embolism are formed in the deep leg veins.Clots also can form in the deep veins of the arms or pelvis.f a large blood clot blocks the artery in the lung, blood flow may be completely stopped, causing sudden death. A smaller clot reduces the blood flow and may cause damage to lung tissue. But if the clot dissolves on its own, it may not cause any major problems. Symptoms of pulmonary embolism usually begin suddenly.

Stroke and blood clots But conditions like hypertension, atherosclerosis and some other blood problems can lead to the development of blood clots. Thrombosis is the name given to the formation of blood clots. When the clot blocks the blood flow to the heart or the brain, a heart attack or stroke can follow. An embolism occurs when a blood clot travels around the body and lodges in an organ. Predisposing conditions for thrombosis. Damage to the blood vessels.

- A blood clot, also known as a thrombus, is a coagulative mass of red blood cells, platelets, and fibers that forms in response to tissue injury. Parts of it can break off, travel through the body, and block blood flow to organs, causing ischemia (tissue damage due to lack of oxygen). Totally different topics.

Venous Blood Clots (Thrombi, DVT) Most tend to dissolve on their own without any problem, but sometimes blood clots can cause medical problems. Blood clots become dangerous when they block blood flow through an artery or a vein. When a blood clot stops blood flow to an artery in the heart or brain, a heart attack or stroke can result. Blood clots also can block veins in other parts of the body, causing conditions like varicose veins or pulmonary embolism (a life-threatening blood clot in the lungs). When a blood clot forms and stays where it forms, it’s called a thrombus.
