Changes in Cardiac Output with Age

Age-related Morphological Changes in Cardiac Valves

The mandate of quality health care includes improved neonatal survival, better maternal and neonatal health and an improved life expectancy, resulting in an increasingly older population with the largest growth in the 65+ age group. Therefore, there is a growing need for an improved awareness of age-related changes in the body in general and in the heart in particular. In addition to risk facto...

Less invasive indicators of changes in thermodilution cardiac output by ventilatory changes after cardiac surgery.

BACKGROUND AND OBJECTIVE We studied whether changes in less invasive, noncalibrated pulse-contour cardiac output (by modified ModelFlow, COmf) and derived stroke volume variations (SVV), as well as systolic and pulse pressure variations, predict changes in bolus thermodilution cardiac output (COtd), evoked by continuous and cyclic increases in intrathoracic pressure by increases in positive end...

Normal cardiac output in relation to age and body size.

The resting cardiac output was measured in 151 healthy persons (109 males and 42 females) of 4 to 78 years of age by the earpiece dye-dilution method by using an automatic calibration device of dye concentration. Cardiac index had a significantly inverse correlation to age in 105 cases with the age higher than 20 years: r=-0.491 and y=-4.874-0.023x, where y is cardiac index (liters/min/m2) and ...
