Journal ArticleDOI
Cardiovascular responses to exercise. Effects of aging and exercise training in healthy men.
TL;DR: There is an age-associated decline in heart rate, ejection fraction, and cardiac output responses to supine exercise in healthy men and both the young and old increased peak exercise cardiac output by use of the Frank-Starling mechanism (ie, cardiac dilatation) as well as an increase in ejectedion fraction.
Journal ArticleDOI
Physical training improves skeletal muscle metabolism in patients with chronic heart failure
S. Adamopoulos,S. Adamopoulos,Andrew J.S. Coats,Andrew J.S. Coats,F Brunotte,Leonard F Arnolda,Theo E. Meyer,Campbell H. Thompson,Jeff F. Dunn,John R. Stratton,Graham J. Kemp,George K. Radda,Bheeshma Rajagopalan +12 more
TL;DR: The reduction in phosphocreatine depletion and in the increase in ADP during exercise, and the enhanced rate of phosphocreatingine resynthesis in recovery indicate that a substantial correction of the impaired oxidative capacity of skeletal muscle in chronic heart failure can be achieved by exercise training.
Journal ArticleDOI
Mechanisms of thrombocytopenia in chronic autoimmune thrombocytopenic purpura. Evidence of both impaired platelet production and increased platelet clearance.
TL;DR: Both depressed platelet production and increased platelet clearance by the liver and spleen contribute to the thrombocytopenia of AITP.
Journal ArticleDOI
Detection of left ventricular thrombus by two-dimensional echocardiography: sensitivity, specificity, and causes of uncertainty.
TL;DR: Patients with proved thrombus had a higher prevalence of electrocardiographic transmural anterior infarction, left ventricular aneurysm, and clinical systemic emboli and these clinical features help to identify a subset of patients most likely to haveleft ventricular thrombi who may benefit from echocardiography.
Journal ArticleDOI
Effect of endurance exercise training on heart rate variability at rest in healthy young and older men
Wayne C. Levy,Manuel D. Cerqueira,George D. Harp,Karl-Arne Johannessen,Itamar B. Abrass,Robert S. Schwartz,John R. Stratton +6 more
TL;DR: Exercise training increases parasympathetic tone at rest in both the healthy older and young men, which may contribute to the reduction in mortality associated with regular exercise.
