Cardiorespiratory responses of cardiac transplant patients to graded, symptom-limited exercise.
The electrocardiographic and ventilatory responses of 15 denervated heart patients who had undergone cardiac transplantation and 14 age-matched, normally innervated men were compared to assess the pattern of response to graded treadmill exercise. A 5-minute postexercise venous lactate sample was also obtained. Respiratory exchange ratio and ventilation (Ve) were higher in denervated patients th...
متن کاملLeft ventricular response to isometric exercise in patients with denervated and innervated hearts.
Patients with cardiac denervation resulting from allograft transplantation have been observed to increase their diastolic and systolic blood pressure during isometric exercise without concomitant cardioacceleration. To determine the mechanism for the blood pressure increase, heart rate, blood pressure, and ventricular volumes (measured using fluoroscopy of tantalum midwall myocardial markers) w...
متن کاملCardiopulmonary response to dynamic exercise after heart and combined heart-lung transplantation.
The exercise capacity and cardiopulmonary response to progressive dynamic exercise of eight healthy recipients of heart-lung transplants were compared with those of matched recipients of orthotopic cardiac transplants and normal controls. In both transplant groups the maximum workloads were lower than that in the normal group. The transplant recipients had higher pre-exercise heart rates and lo...
متن کاملAbnormal neuroendocrine responses during exercise in heart transplant recipients.
BACKGROUND Osmotic and neural factors stimulate neuroendocrine activity during exercise. In contrast to excitatory mechanisms, afferent information from cardiac mechanoreceptors inhibits integrative centers in the hypothalamus and medula oblongata, which serves to buffer neuroendocrine activity. Orthotopic cardiac transplantation results in the loss of afferent information from cardiac mechanor...
متن کاملExercise response after cardiac transplantation: correlation with sympathetic reinnervation.
OBJECTIVE To investigate the relation between sympathetic efferent reinnervation and chronotropic competence during exercise testing after cardiac transplantation. PATIENTS Twenty five long-term cardiac transplant recipients and 11 normal controls. SETTING Regional cardiothoracic centre. METHODS Intracoronary tyramine was given to the transplant recipients and the per cent heart rate chan...
