Coronary heart disease patients have poor quality of life

Washington, July 15 (ANI): Better treatments boost survival rates of coronary heart disease patients, but the quality of those extra years may be less than ideal, according to a new study.
Adults with cardiovascular trouble scored up to 9 percent lower on four scales measuring their quality of life, when compared with adults without coronary heart disease (CHD).
Lead author Jipan Xie, M.D., Ph.D., former health scientist in the Division for Heart Disease and Stroke Prevention at the Centers for Disease Control and Prevention in Atlanta, Ga, said that patients with coronary heart disease were more likely to say they had poorer quality of life, or describe themselves as sick.
Those most likely to report poorer quality of life in this study were between the age group of 18 to 49; women; and black or Hispanic.
Xie said that the age-related difference probably reflects a difference in age-related expectations.
“Younger people may feel more pressure - especially younger men - in the workplace and may be more threatened by limitations imposed by their disease,” she said.
Older people, especially those who were older than 65, were less likely to say heart disease limited their life or had an adverse effect on their quality of life.
“The implications of these findings underscore the need for interventions aimed at improved health-related quality of life for people with coronary heart disease - a population that has been growing rapidly,” she said.
For the study, researchers used data from the 2000 and 2002 Medical Expenditure Panel Surveys and they identified 2,091 people with a history of coronary heart disease from a sample of 37,386 individuals.
On average, CHD patients had 2.4 percent lower mental health scores; 4.6 percent lower health utility scores - which measured mobility, self-care, usual activity, pain and anxiety; 9 percent lower self-ratings of health; and 9.2 percent lower physical health scores.
Researchers noted that men and women with heart disease rated lower on the mental health measure than did participants free of CHD.
Yet, while self-rated health scores indicated that men were more affected by CHD than women, physical health scores indicated women with heart disease had more functional impairment than men.
Xie said contradictory findings are fairly common in these types of analyses, but the findings suggest a disconnect between self-perception and functional ability.
Researchers said the study is limited because the disease status was self-reported and patients had various stages of CHD and treatments.
Also, there was not enough information to explain the differences in patient-reported health status among demographic subgroups.
The study is published in Circulation: Journal of the American Heart Association. (ANI)
