...Mike Fackelmann had no reason to think he had heart disease. Although his cholesterol was a touch on the high side, he had never experienced any chest pains and had just passed a stress test with flying colors. So last November, when a cardiologist at the Cleveland Clinic Foundation Hospital asked the then 49-year-old registered nurse to help demonstrate an experimental new cardiac scanner, neither the physician nor Fackelmann expected to see anything out of the ordinary. The idea was simply to slide Fackelmann through the machine and show what finely detailed images of the heart it could...
...favor Fackelmann did may well have saved his life. The scan revealed a major blockage in one of his coronary arteries. A few days later, doctors propped open the dangerously clogged blood vessel with a stent, thereby preventing what could have been a heart attack. "I would have been one of those guys who was just out jogging with my son or playing basketball and died," Fackelmann says. "There was never any reason for me to suspect that there was such a dramatic lesion in my heart...
What makes this story all the more remarkable is that the image that changed Fackelmann's future was generated without any kind of surgery. For years, the gold standard for discovering the location of blockages in a patient's coronary arteries has been a procedure called a cardiac catheterization, in which a specialist inserts a probe through an incision into a blood vessel in the groin, then snakes it up toward the heart, where an opaque dye is released...
...Leading the way are improvements in CT (for computed tomography) scanning, which uses highly specialized X-ray machines to take multiple, finely layered pictures of the heart and surrounding blood vessels. Sophisticated computer programs sort the data to generate amazingly detailed, three-dimensional images like the ones that alerted Fackelmann's doctors to his hidden heart problem. Advances in other techniques like MRI (magnetic resonance imaging) have astonished physicians with the clarity of details now available to them on the inner workings of the heart...
...racing to keep up with these changes. In July, the American College of Cardiology and the American Heart Association published their first guidelines on how to train doctors to perform the new cardiac scans. Three studies have shown that cardiac CT is 90% accurate at picking up blockages like Fackelmann's. But no standards have been written yet for determining under what conditions using the new scans makes the most sense, and for which patients. More definitive answers may be forthcoming at the annual American Heart Association meeting in November, when several research groups are expected to present their latest...
