The authors undertook this study to determine the effects of age, gender, and heart rate (HR) on the results of cardiac autonomic function tests for measuring heart rate variability (HRV) in a large sample of healthy subjects ( n =309). Conventional tests (deep breathing, maximum/minimum 30...

Six-minute walk distance (6MWD) of 300 and 400 m are important targets of functional capacity. The present study was performed to determine cutoff values of physical function associated with 6MWD < 300 m and < 400 m in elderly patients with heart failure (HF). 6MWD, handgrip st...
Purpose To review our experience with exercise stress tests (EST) in children and young adults with history of heart failure(HF), and to determine which exercise parameters are useful to stratify risk in these patients. Methods and Materials This is a retrospective review of HF pts at a ...
Your doctor may be able to determine what heart condition you may have depending on which part of your results were abnormal. If my EKG is normal, is my heart OK? It's possible to have normal EKG results and still have a heart condition.You might need further testing before your doctor...

Optimal testosterone levels may support healthy mood, libido, body composition, and cardiovascular wellness. You may wish to discuss with your doctor the use of supplements such as DHEA and pregnenolone. Speak to your physician to determine whether prescription testosterone may also be helpful for you...
1.A graded test to measure an individual's heart rate and oxygen intake while undergoing strenuous physical exercise, as on a treadmill. 2.A test performed on a system or organization to determine its susceptibility to failure under various conditions. ...
Wrist-worn devices with heart rate monitoring have become increasingly popular. Although current guidelines advise to consider clinical symptoms and exercise tolerance during decision-making in heart disease, it remains unknown to which extent wearables can help to determine such functional capacity measures...
MCG researchers also want to use their assays to look at levels of active ANP and corin in a larger number of patients to determine whether corin levels are a good predictor/indicator of heart failure. "Corin levels were low in heart failure patients but we can't say when they dropped," ...
