...impede, or even stop, the passage of blood through the artery in which the condition exists. As the volume and surge of the blood decrease, a clot may form, often quite suddenly, around one of the rough projections that has grown on the arterial wall. The clot is a thrombus, the process of its formation is thrombosis, and if it happens in one of the coronary arteries, it is coronary thrombosis (while there are medical distinctions in their precise use, the terms "coronary occlusion" and "cardiac infarction" are generally synonymous with "coronary thrombosis...
...stuck by his claims through all the minute cross-examination of yesterday and today, reversing himself on only one point. Ford admitted this morning that if the hypodermic neodie had entered Mrs. Borroto's vein, he "didn't believe the air would stop at the thrombus"--the blood clot that dammed the upper part of the vein...
...Smooth Flow. Most dreaded and suddenly fatal of all heart ailments are those due to bloodclotting, e.g., coronary thrombosis. For reasons not yet perfectly understood (too little exercise, poor metabolism, infection), blood cells sometimes begin to stick together to form a thrombus (a stationary clot). But the thrombus grows, may eventually let loose daughter clots (emboli) which swim on to lodge at vital bottlenecks in the blood stream. A thrombus which lodges in a coronary (heart) artery, blocking off the blood supply to the heart muscle, can kill within a few minutes; a clot in the brain causes a stroke...
...confused with embolism. A thrombus stays in one place; an embolus, which might be a blood clot, or a pocket of air or oil, moves through the blood stream. If an embolus settles down, it becomes a thrombus...
...keep him alive for months. Like all muscles, the heart requires the nourishment of blood. It gets this blood through two coronary arteries which tap off from the aorta just after it springs from the hollows of the heart. If a coronary artery is clogged by a blood clot (thrombus), or is narrowed by hardening, the heart cannot get enough blood to survive. Before it dies, it causes the terrifying signal of pain called angina pectoris...
