EKG Heart Test May Predict Risk in Older Adults
News from MSN Health & Fitness:
TUESDAY, April 10 (HealthDay News) ? Minor changes in the results of a commonly used heart test ? an electrocardiogram, or EKG ? translate into a 35 percent increased risk of heart events, such as heart attacks, hospitalizations for chest pain or the need for heart surgery, in people over 70, according to new research.
For people with major abnormalities in their EKG, the risk of having a heart event is even higher, compared to people with normal tests.
?We analyzed data from the Health, Aging and Body Composition Study. More than 3,000 patients had an electrocardiogram done at baseline, but we only included the people who didn?t have a previous history of coronary heart disease or cardiovascular disease, so no heart attacks or strokes,? said lead study author Dr. Reto Auer, a research fellow in the department of epidemiology and biostatistics at the University of California, San Francisco.
?We found that people who had minor or major changes in their electrocardiogram had a greater risk of heart events,? Auer said. ?And, when we adjusted the data for commonly known risk factors ? smo????? continues on MSN Health & Fitness

ECG Abnormalities in Elderly Linked to Increased CHD
News from Family Practice News Digital Network:
Both major and minor abnormalities on electrocardiogram signaled an increased risk of coronary heart disease within 8 years among elderly people in the general population, according to a report in the April 11 issue of JAMA.
Adding ECG abnormalities to traditional cardiovascular risk factors in a risk prediction model modestly but significantly improved the prediction of coronary heart disease events, said Dr. Reto Auer of the department of epidemiology and biostatistics, University of California, San Francisco, and associates.
To date, few studies have examined whether ECG abnormalities could improve risk prediction in older adults, and none have adequately adjusted for the presence of traditional cardiovascular risk factors. Predicting CHD with traditional risk factors is less accurate in the elderly than in other patient populations, the investigators noted.
Dr. Auer and colleagues examined the issue using data from the Health, Aging, and Body Composition (Health ABC) Study, a population-based cohort study of community-dwelling men and women who were aged 70-79 years at baseline in 1997-1998. For their secondary analysis of data from this study, the investigat????? continues on Family Practice News Digital Network
