Can a Blood Clot Be Fatal?
A blood clot can be fatal when it blocks a vital artery or travels to the lungs or brain. A pulmonary embolism, which occurs when a clot reaches the lungs, is a common cause of death from a blood clot. According to the American Heart Association, blood clots cause thousands of deaths each year in the United States.
Common Causes and Risk Factors
Deep vein thrombosis, or DVT, is a clot that forms in a deep vein, usually in the leg. It becomes dangerous if it breaks loose and travels to the lungs. Risk factors include prolonged immobility, surgery, cancer, pregnancy, obesity, and certain genetic clotting disorders. Long periods of sitting, such as during travel, can also increase the risk.
Warning Signs and When to Seek Help
Warning signs of a dangerous clot include sudden shortness of breath, chest pain, rapid heartbeat, and coughing up blood. A clot in the brain can cause a sudden severe headache, confusion, or trouble speaking. Immediate medical attention is critical because early treatment greatly improves survival chances.
