Heartfelt from page 25 duce, a light bulb went on. But the switch had been flipped many times before' The two-year Beaumont study involved 197 patients who were recruited as they came into the emergency room with heart attack symptoms. Randomly, half were assigned to have the CT scan and the oth- ers to undergo standard diagnostic treat- ment. "Our research showed coronary CT angiography can detect if arteries are nor- mal or diagnose mild, moderate or severe blockages with a high degree of accuracy, exceeding 95 percent, without invasive cardiac catheterization;' Goldstein said. "The holy grail of the field is to detect these plaques (blockages)!" Six million patients annually seek emergency treatment for chest pain in the United States, according to the Journal of the American College of Cardiology, which published Goldstein's account of the Beaumont study in its February issue. "At least half have inconclusive early test results and, of these, approximately 65 percent are eventually found not to have suffered a heart attack;' the journal stated. A new, larger study of 750 low-risk patients across the country will test Beaumont's results. "For research like this, it's early:" Goldstein acknowledged. "The most impor- tant part is the limitations of this study." He says, for instance, that the CT scan is less helpful for patients who are known to have coronary artery disease and may not produce clear images in obese patients. Radiation's Effect In an editorial that accompanied Goldstein's article, the issue of radiation exposure was raised. And, the Journal's editor-in-chief, Dr. Anthony N. DeMaria, wrote: "These data demonstrate a potential application of CT angiography for the rapid assessment of chest pain in the emergency room. However, it must be acknowledged that the patient population was limited ... and that the primary benefit was in detecting abnormalities sooner and more inexpen- sively, but not more accurately. The effect of the earlier diagnosis upon outcome also remains to be determined." "The best papers say: I'm beautiful but I've got a blemish right here Goldstein pointed out. "I'm very confident that our results are accurate Indeed, Beaumont is regularly using CT testing for its low-risk patients. This isn't the first potential break- through in which Goldstein has been involved. One important contribution derived from work demonstrating that patients with heart attacks typically har- bored more than one unstable region in their arteries. Until then, a heart attack was always thought to be a local vascular accident, he said. "We showed that 50 percent of patients have at least one other unstable blockage; that the area that announces the problem is only the tip of the iceberg!" Another long-standing area of inter- est has been in patients who suffer heart Dr. Gilbert Raff, standing, and Dr. James Goldstein view CT-delivered heart images on a computer screen. Recognize Heart Attack Symptoms C hris Simpson, a Troy wife, mom and grandmother, is a ready spokeswoman for the CT scan. At 59, she had a strong fami- ly history — father, mother and brother — of heart disease. "My dad died of his fourth heart attack and my brother had a heart attack and bypass surgery in his early 40s," she said. "I was aware of the kind of symp- toms that women have and that they can be different from men," she said. So when, in 2005, Simpson experi- enced several. bouts of moderate dizzi- ness and jaw ache after exercising, she headed to Beaumont Hospital-Royal 26 April 26 • 2007 Oak where she agreed to be part of the study. "I wasn't even experiencing any pain at the time," she said. She drew the CT scan, which quickly showed a lesion as well as other blocked arteries. She had one stent put in at the time, then over a few more weeks, three more. "I was happy to participate," Simpson said. "One of the best advan- tages is that it is done very quickly and quick response to heart attacks controls damage." Simpson, a writer/designer for 0/E Learning in Troy, is on a regimen of cholesterol and .blood pressure-reduc- ing drugs; she has had no recurrence of symptoms. "I have the feeling that I dodged the bullet," she said. Coronary disease is America's No.1 killer, according to the American Heart Association. Recognizing symptoms of a heart attack and getting to the hos- pital immediately could be the differ- ence between life and death, the heart association says. Some heart attacks are sudden and intense — the "movie heart attack" where no one doubts what's hap- pening. But most heart attacks start slowly, with mild pain or discomfort. Often, people affected aren't sure what's wrong and wait too long before getting help. The American Heart Association warns you to call 911 if you have any of the following symptoms: •Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain. •Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach. •Shortness of breath, with or with- out chest discomfort. •Other signs may include breaking out in a cold sweat, nausea or light- headedness. •Women should be alert to the fact that although chest pain or discom- fort is a sign, they are more likely to experience some of the other common symptoms, particularly shortness of breath, nausea/vomiting and back or jaw pain. - Judith Doner Berne
