Effects of coronary vasodilators on large and small coronary arteries of dogs. 1977

K Takeda, and Y Nakagawa, and Y Katono, and S Imai

Using the isolated perfused heart preparation supported by a donor the effects of vasodilators on the large conductance artery were studied and were compared with those on the small resistive artery and arterioles. Nitroglycerin produced a preferential dilation of the large conductance artery, while dipyridamole produced a dilation only of the small resistive artery and arterioles. Among the "calcium antagonistic" vasodilators tested, only diltiazem produced a dilatation of the large conductance artery, verapamil and nifedipine producing a dilatation only of the small resistive artery and arterioles. These findings indicate that the mechanism of contraction of the large conductance artery is different from that of the small resistive artery and arterioles.

UI	MeSH Term	Description	Entries
D007511	Ischemia	A hypoperfusion of the BLOOD through an organ or tissue caused by a PATHOLOGIC CONSTRICTION or obstruction of its BLOOD VESSELS, or an absence of BLOOD CIRCULATION.	Ischemias
D007548	Isosorbide Dinitrate	A vasodilator used in the treatment of ANGINA PECTORIS. Its actions are similar to NITROGLYCERIN but with a slower onset of action.

D009543	Nifedipine	A potent vasodilator agent with calcium antagonistic action. It is a useful anti-anginal agent that also lowers blood pressure.

D004176	Dipyridamole	A phosphodiesterase inhibitor that blocks uptake and metabolism of adenosine by erythrocytes and vascular endothelial cells. Dipyridamole also potentiates the antiaggregating action of prostacyclin.

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D004896	Erythritol	A four-carbon sugar that is found in algae, fungi, and lichens. It is twice as sweet as sucrose and can be used as a coronary vasodilator.
D005996	Nitroglycerin	A volatile vasodilator which relieves ANGINA PECTORIS by stimulating GUANYLATE CYCLASE and lowering cytosolic calcium. It is also sometimes used for TOCOLYSIS and explosives.
