Doctors edge closer to identifying heart risks
More than 1 million people in the United States will have a heart attack this year. Most will occur in people with no symptoms. With better prediction methods for cardiovascular disease, many of those could be prevented. Two new studies in the Journal of the American Medical Association explore methods for helping doctors identify patients who are at greatest risk for heart problems. They are not definitive, and still point to unanswered questions, but represent a continued fight against the most common killer in the United States. One new study found that coronary artery calcium was about six times better at predicting cardiovascular risk than a family history of coronary heart disease.
