know Thrombosis

Thrombosis refers to abnormal, life-threatening blood clots that form in the artery or vein. A clot in the vein (usually in the leg or pelvis) is known as a deep vein thrombosis (DVT) and a clot that breaks off and travels to the lungs is known as a pulmonary embolism (PE). Together, DVT and PE make up venous thromboembolism (VTE).

Know Atrial Fibrillation

Atrial Fibrillation (AFib) is a common type of arrhythmia, or irregular heartbeat. Because the heart beats and contracts irregularly, blood flow may slow or pool and cause the formation of a clot. This clot is an example of arterial thromboembolism. If it breaks free, it can lodge in an artery, travel to the brain and result in a stroke. Know the risk factors for a stroke. Take action.
