Latest Left ventricle Stories
American Heart Association Journal Report:Study Highlights:   * The size and pumping ability of the right side of the heart differs by age, gender and race/ethnicity, according to the first large imaging study of the right ventricle.   * Defining the right ventricular norms for different populations could aid in identifying abnormal right ventricle size and function.   * Abnormal right ventricle function may be a sign of conditions that involve both the heart and...
Hibernating, it turns out, is much more complicated than one might think.Research published in the latest issue of the journal Physiological and Biochemical Zoology illustrates a complex series of changes that occur in grizzly bears' hearts as they hibernate. The changes guard against complications that could arise from greatly reduced activity.A grizzly hibernates five to six months of the year. During that time, its heart rate slows drastically from around 84 beats per minute when active to...
Study highlights:   * New, precise imaging of the heart's motions showed important differences between men and women and different age groups.   * The gender differences in heart motion were not all explained by anatomical differences.   * The new imaging technique could lead to earlier diagnosis of cardiovascular disease.Using a new noninvasive imaging technique, scientists said they have discovered important, fundamental differences in heart motion by age and...
Patients with abnormal diastolic function -- the heart is relaxed and expanded -- in the left ventricle have a lower exercise capacity, U.S. researchers say. Dr. Jasmine Grewal of the Mayo Clinic in Rochester, Minn., and colleagues studied the relationship between left ventricular diastolic function and exercise capacity. The study included 2,867 patients undergoing exercise echocardiography -- a noninvasive diagnostic procedure that uses ultrasound to study the structure and motions of the...
An abnormal heart condition could affect how much you can exercise. New research shows patients with abnormal diastolic function "“ when the heart relaxes and expands "“ in the left ventricle of the heart have a substantially lower maximum capacity for exercise.There are factors known to decrease one's capacity for exercise, including age, female sex, a body mass index greater than 30 and co-existing medical conditions. However, new research suggests assessing left ventricle function...
New research shows that exercise can cause structural changes in the heart depending on the type of exercise being done.Researchers found a size increase in both the left and right ventricles in athletes after 90 days of team training. Athletes that only did strength training showed excessive growth in their left ventricles, but no change in their right ventricle size.Dr. Aaron L. Baggish of Massachusetts General Hospital in Boston and colleagues found that while the ability of the left...
Overweight people who lose a moderate amount of weight get an immediate benefit in the form of better heart health, according to a study conducted at Washington University School of Medicine in St. Louis. And the heart improvements happen whether that weight is shed by eating less or exercising more."If individuals want to do something that's good for their heart, then my message to them is lose weight by the method they find most tolerable," says the study's senior author Sándor...
