Coronary Vasomotor Response After Riociguat Exposure (CORONARIES)
The aim of the study is to assess the effects of intracoronary Riociguat on coronary blood flow in subjects with coronary artery disease and to compare this effect with the intracoronary nitroglycerin, a coronary vasodilator widly used to treat patients with coronary artery disease.

|Official Title:||A Study to Compare the Acute Coronary Vasodilating Effects of the sGC Stimulator Riociguat (BAY 63-2521) With the Nitric Oxide Donor Nitroglycerin in Patients With Coronary Artery Disease|
- The ratio of the coronary blood flow after Riociguat to the corresponding flow observed after adenosine, compared to that after nitroglycerin administration [ Time Frame: Within 5 min after completion of the intracoronary Riociguat infusion ] [ Designated as safety issue: No ]
- Adverse event collection [ Time Frame: Until 30 days after study drug treatment ] [ Designated as safety issue: Yes ]
