Augmented response of endothelin-A and endothelin-B receptor stimulation in coronary arteries of hypertensive hearts.


To determine whether the vasoconstrictor response to endothelin-1 (ET-1) is altered in coronary vessels of hypertensive hearts and the role of ETA and ETB receptors in these responses to ET-1, the vasoconstrictor response to ET-1 in coronary vessels was measured with or without ETA and ETB receptor antagonists. In isolated hearts of spontaneously… (More)
