Abnormal Heart Function Associated With Reduced Capacity For Exercise
Patients with abnormal diastolic function (when the heart is relaxed and expanded) in the left ventricle of the heart have a substantially lower maximum capacity for exercise, according to a study in the January 21 issue of JAMA.
Many factors, including age, female sex, body mass index and co-existing medical conditions are known to be associated with a decrease in exercise capacity. Identifying potentially reversible mechanisms underlying the decline in maximum exercise capacity could have important implications. Some research has suggested that assessing left ventricular (one of four chambers in the heart) function could be used to predict exercise capacity, according to background information in the article.
