[Reaction of hemodynamic parameters to coronary angiography with two different age groups (author's transl)]

Two groups of patients (A = 19 less than 50 a; B = 21 greater than 50 a) were supervised during coronary injection as to cardiac and pulmonary pressure. In both groups there is an equivalent increase of the cardiac index by 20%, the initial value being lower in groups B. The increase lasts for more than 2 Min. During 5 Min the pulmonary pressure is increased by 25%. The reaction is based on an intracellular calcium flow induced by contrast medium.
