The paper presents new evidence of the vasoactivity of cardiac glycosides in the myocardium. Experiments were performed on the in situ dog heart. The present study primarily focuses on the analysis of K-strophantoside induced topo-optical and thermographic alterations in acute myocardial ischemia. The strong binding of K-strophantoside to the coronary vessel wall and the endothelial cells was found to be accompanied by vasoconstriction in the regionally ischemic heart muscle. The potential clinical impact of these findings on therapy is briefly evaluated.

D008859	Microscopy, Polarization	Microscopy using polarized light in which phenomena due to the preferential orientation of optical properties with respect to the vibration plane of the polarized light are made visible and correlated parameters are made measurable.

D002301	Cardiac Glycosides	Cyclopentanophenanthrenes with a 5- or 6-membered lactone ring attached at the 17-position and SUGARS attached at the 3-position. Plants they come from have long been used in congestive heart failure. They increase the force of cardiac contraction without significantly affecting other parameters, but are very toxic at larger doses. Their mechanism of action usually involves inhibition of the NA(+)-K(+)-EXCHANGING ATPASE and they are often used in cell biological studies for that purpose.

D003326	Coronary Circulation	The circulation of blood through the CORONARY VESSELS of the HEART.	Circulation, Coronary
D003327	Coronary Disease	An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
