Vasorelaxing effects of the soluble guanylyl cyclase activator BAY 60-2770 in nitrate-tolerant monkey and canine coronary arteries.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Nitrate tolerance is an important problem in the treatment of ischemic heart diseases. The present study investigated whether or not a soluble guanylyl cyclase (sGC) activator can be used as a coronary vasodilator under nitrate-tolerant conditions. Helically cut strips of endothelium-denuded monkey and canine coronary arteries were suspended in organ chambers for isometric tension recording. Nitrate tolerance was induced by a 1-h treatment with nitroglycerin (0.1 mM) followed by 1-h washout of the agent. Control strips were not exposed previously to nitroglycerin, but otherwise were treated identically. The relaxant response to nitroglycerin was dramatically impaired by previous exposure to the drug for 1 h in either monkey or canine coronary arteries, indicating the development of nitrate tolerance. In contrast, development of nitrate tolerance did not affect the relaxant potency and efficacy of the sGC activator BAY 60-2770 in either the monkey or canine coronary arteries. These findings suggest that it may be possible to use sGC activators as substitute drugs for nitroglycerin if tolerance is developed during the treatment of ischemic heart diseases.
