The contraction of the heart muscle starts in the two atria, which push the blood into the ventricles. Then the walls of the ventricles squeeze together and force the blood out into the arteries: the aorta to the body and the pulmonary artery to the lungs.
In 1875, blood clots in the heart were found to cause strokes. It was established that blood clots were not only capable of developing in arteries and veins, but inside the heart as well. A blood clot in the heart--also referred to as cardiogenic embolism--can be fatal. Blood clots can travel to the brain, cutting off blood supply and causing a stroke. A stroke coming from a blood clot in the heart is classified as an ischemic stroke. The result is death of brain cells, swelling and subsequent brain damage.
