OBJECTIVES This study assessed the incremental value of technetium-99m myocardial single-photon emission computed tomography (SPECT) and simultaneous first-pass radionuclide angiography, when added to treadmill exercise, for prediction of the extent of coronary artery disease. BACKGROUND Technetium-99m count statistics permit the simultaneous assessment of myocardial perfusion and function. H...

The prophylactic antianginal efficacy of nitroglycerin (NTG) oral spray was assessed in 20 patients with angiographically documented coronary disease and stable angina pectoris. The evaluation was by a randomized crossover trial involving treadmill exercise testing. On study day 1, a control treadmill exercise test was performed, followed 30 minutes later by a second exercise test 2 minutes aft...

OBJECTIVE To examine blood pressure (BP) in sedentary African American women during two exercise intensities on a cycle and treadmill at fixed heart rate (HR) values. METHODS Blood pressure (BP) and heart rate (HR) were assessed in 44 women (age 33.1 +/- 8.2 years) during cycling and treadmill walking at 40% and 60% heart rate reserve (HRR). Systolic blood pressure (SBP) and diastolic blood p...

The present study aimed to clarify changes of oxidative stress and antioxidative functions in treadmill-exercised Thoroughbred horses (n=5, 3 to 7 years old), using recently developed techniques for measurement of serum d-ROMs for oxidative stress, and BAP for antioxidative markers. Also, the effect of nasogastric administration of hydrogen-rich water (HW) or placebo water preceding the treadmi...

Post-traumatic stress disorder (PTSD) is a condition which occurs after a person has experienced unusual stress. The neurons in the hippocampus are especially vulnerable to the PTSD. In the present study, the effect of treadmill exercise on spatial learning memory and cell proliferation in the hippocampus of rats with PTSD. Radial 8-arm maze test and immunohistochemistr for 5-bromo-2'-deoxyridi...

BACKGROUND Preoperative evaluation of lung resection candidates with impaired pulmonary reserves includes measurement of aerobic capacity. Stair climbing is an attractive low-cost alternative to treadmill exercise testing but it lacks standardisation. OBJECTIVES To directly compare stair climbing and treadmill exercise testing with respect to an established cut-off value for lung resection. ...

BACKGROUND The initial response of heart rate to dynamic exercise has been proposed as having prognostic value in limited studies that have used modalities other than the treadmill. Our aim was to evaluate the prognostic value of early heart rate parameters in patients referred for routine clinical treadmill testing. METHODS AND RESULTS The heart rate rise at the onset of exercise was measure...
