Studies with intravenous triolein with relation to age of patient^*

Triolein labeled with I¹³¹ was given intravenously to 27 normal controls, 20 coronary heart disease patients and a miscellaneous group of 10 patients. When curves of the disappearance rate were constructed and analyzed, it was apparent that (1) there was no difference between patients with corcnary heart disease and controls, and (2) there was a statistically significant correlation between age and the disappearance rate up to eight hours, and between age and 24-hour radioactivity in all subjects regardless of clinical category. The significance of these findings is discussed in relationship to previous studies in which age matching was lacking.
