How long you can live with a blood clot in your heart depends on the underlying heart disease. For example, atrial fibrillation, which is commonly known as atrial fibrillation caused by attached wall thrombus, only need to take long-term anticoagulant drugs to prevent thrombus dislodgement caused by cerebral embolism or other organs embolism can be, generally does not have a great impact on life expectancy. If it is dilated cardiomyopathy, heart failure caused by epiphyseal thrombus, life expectancy depends entirely on the underlying disease, if it is a severe heart failure, the 5-year survival rate is only about 50%, so it is inferred that 50% of patients can survive for 5 years, and it has little to do with thrombus. If there is a thrombus, anticoagulation is needed, and in some patients the thrombus can disappear completely after 3 months of anticoagulation.
