Exercise capacity before and after cardiac valve surgery. 1983

V Carstens, and D W Behrenbeck, and H H Hilger

Exercise stress testing and right-heart catheterization were carried out in 131 patients before and 6 months after cardiac valve surgery. The exercise capacity increased only a little in patients with mitral or double-valve surgery. In contrast, most patients with an aortic valve replacement had good exercise performance after surgery. Corresponding to the reduced exercise capacity most of the patients also had disturbed hemodynamics after surgery, with an elevated mean pulmonary artery pressure at rest, that raised inappropriately during exercise, and a diminished cardiac output at rest, that failed to increase during exercise, in relation to oxygen uptake.

D010101	Oxygen Consumption	The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body.

D011669	Pulmonary Wedge Pressure	The blood pressure as recorded after wedging a CATHETER in a small PULMONARY ARTERY; believed to reflect the PRESSURE in the pulmonary CAPILLARIES.

D002302	Cardiac Output	The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).	Cardiac Outputs,Output, Cardiac,Outputs, Cardiac
D005080	Exercise Test	Controlled physical activity which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used.

D005082	Physical Exertion	Expenditure of energy during PHYSICAL ACTIVITY. Intensity of exertion may be measured by rate of OXYGEN CONSUMPTION; HEAT produced, or HEART RATE. Perceived exertion, a psychological measure of exertion, is included.	Physical Effort,Effort, Physical,Efforts, Physical,Exertion, Physical,Exertions, Physical,Physical Efforts,Physical Exertions
