Coronary circulation

Question 1

What happens to cardiac efficiency in patients with hypertension?

Answer 1

Cardiac efficiency is considerably reduced in situations of increased ventricular pressure, such as in hypertension or aortic stenosis.

Question 2

What do you think happens if there is denervation of the heart after heart transplant surgery?

Answer 2

Denervation of the heart is initially followed by a reduction in coronary vascular resistance. Thus the net effect of the neural influence seems to be constriction rather than dilatation.
