Cardiovascular disease (CAD) screening in asymptomatic patients with diabetes mellitus is controversial. An exercise stress test is a safe and effective initial testing for Ischemic Heart Disease (IHD) screening. Treadmill stress test is not the best screening method for a particular patient who is not able to exercise, abnormal electrocardiogram (ECG) or positive exercise treadmill test (ETT) ...

OBJECTIVES To investigate the diagnostic and prognostic value of ST segment depression limited to the recovery phase of an exercise stress test, as compared with that of ST segment depression appearing during exercise. SETTING Exercise stress test laboratory of a university hospital. PATIENTS AND DESIGN Clinical and angiographic data were compared for 574 consecutive patients who developed ...

Objectives: To investigate the diagnostic and prognostic value of ST segment depression limited to the recovery phase of an exercise stress test, as compared with that of ST segment depression appearing during exercise. Setting: Exercise stress test laboratory of a university hospital. Patients and design: Clinical and angiographic data were compared for 574 consecutive patients who developed S...

BACKGROUND Analgesic effect of exercise is a well established fact; however available reports are contradictory on gender differences in pain perception following exercise stress test. OBJECTIVE The current study is prospectively designed to evaluate and compare the effect of acute bout of sub-maximal exercise stress on cold pressor pain in normal adult males and females. METHOD The experim...

OBJECTIVES In this study, we sought to assess safety of symptom-limited exercise stress tests the day after coronary stenting. BACKGROUND Isolated cases of coronary stent thrombosis have been linked to early exercise stress testing, thereby questioning the safety of unrestricted physical activity after the coronary procedure. METHODS At a single center, 1,000 patients were randomized to a s...

This study was designed to assess the effects of age and physical fitness on vagal modulation of heart rate (HR) during exercise by analyzing the instantaneous R-R interval variability from Poincaré plots (SD1) at rest and at different phases of a bicycle exercise test in a population of healthy males. SD1 normalized for the average R-R interval (SD1n), a measure of vagal activity, was compared...

Graded exercise testing (GXT) is the most widely used assessment to examine the dynamic relationship between exercise and integrated physiological systems. The information from GXT can be applied across the spectrum of sport performance, occupational safety screening, research, and clinical diagnostics. The suitability of GXT to determine a valid maximal oxygen consumption (VO2max) has been und...

BACKGROUND When the subject is not able to satisfy traditional testing procedures, alternative exercises or indices such as arm cranking or the oxygen uptake efficiency slope (OUES) have been proposed. However, the OUES has not yet been used on elderly subjects from an exercise performed with the arms. OBJECTIVE The aim of our study was to evaluate the possibility of using the OUES as an inde...

Cigarette smokers experience an exaggerated triglyceride (TAG) and oxidative stress response to high fat feeding. Exercise training may serve to attenuate the rise in these variables, by improving TAG clearance and antioxidant defense. We compared blood TAG, antioxidant capacity, and oxidative stress biomarkers in exercise trained (>2 hrs per wk) and untrained smokers matched for age, in respon...

BACKGROUND Although basic research has uncovered biological mechanisms by which exercise could maintain and enhance adult brain health, experimental human studies with older adults have produced equivocal results. PURPOSE This randomized clinical trial aimed to investigate the hypotheses that (a) the effects of exercise training on the performance of neurocognitive tasks in older adults is se...
