Heart-Healthy Exercise

Exercise in a Healthy Heart Program: A Cohort Study

OBJECTIVE To assess the effects of exercise on resting heart rate (RHR), weight, lipid profile, and blood pressure. We hypothesized that the participants who increased their physical activity would show improvement in their cardiovascular risk factors compared to those who did not. DESIGN Retrospective chart review over the mean duration of 4.9 years of follow-up. SETTING Healthy Heart Prog...

Exercise, Heart and Health

Regular physical activity provides a variety of health benefits, including improvement in cardiopulmonary or metabolic status, reduction of the risk of coronary artery disease or stroke, prevention of cancer, and decrease in total mortality. Exercise-related cardiac events are occasionally reported during highly competitive sports activity or vigorous exercises. However, the risk of sudden deat...

Exercise and the heart.

Comparison of formulae for heart rate correction of QT interval in exercise ECGs from healthy children.

OBJECTIVE To investigate the differences in four formulae for heart rate correction of the QT interval in serial ECG recordings in healthy children undergoing a graded exercise test. SUBJECTS 54 healthy children, median age 9.9 years (range 5.05-14.9 years), subjected to graded physical exercise (on a bicycle ergometer or treadmill) until heart rate reached > 85% of expected maximum for age. ...

Vortex formation ratio in heart failure compared to healthy volunteers at rest and during exercise

Background Heart failure is associated with high mortality, and diagnosis lacks reliable quantitative measures. Therefore, new measures of heart failure are needed. Vortex formation ratio (VFR) [1] is a method to describe the optimal vortex blood flow during rapid filling of the left ventricle (LV) of the heart. VFR has previously been determined using echocardiography [2] and has been proposed...
