Some of the conditions in which blood clots develop include atrial fibrillation (a form of cardiac arrhythmia), heart valve replacement, a recent heart attack, extended periods of inactivity (see deep venous thrombosis), and genetic or disease related deficiencies in the blood's clotting abilities. Thrombi may cause obstruction of arteries and veins and they are possible sources of emboli. Preventing blood clots reduces the risk of stroke, heart attack and pulmonary embolism. Heparin and warfarin are often used to inhibit the formation and growth of existing blood clots, thereby allowing the body to shrink and dissolve the blood clots through normal methods (see anticoagulant). Atrial fibrillation (AF or afib) is a cardiac arrhythmia (an abnormality of heart rate or rhythm) originating in the atria. ...
