Abstract/OtherAbstract:
Heart rate (HR), cardiac output (CO), coronary sinus blood flow (CSF), left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), mean arterial (MAP), and coronary arteriovenous difference for oxygen (AVDcO2) were measured in patients with stable angina pectoris without cardiac failure before and 40 to 60 minutes after administration of 2 or 3 mg of molsidomine. In 20 patients these measurements were made in basal state during spontaneous rhythm. In eight of these patients (including three receiving beta blockers) the measurements were made during atrial pacing. In eight other patients, all receiving long-term beta-blocker therapy, the measurements were made during cold pressor test. At the basal state in spontaneous rhythm, a gradual reduction in the LVSP to 70% or less of its initial value was observed in four patients receiving 3 mg of molsidomine (two of whom received beta-blocker treatment). The LVSP was immediately restored by vascular filling. In the 16 other patients molsidomine decreased LVSP, LVEDP, MAP, CO, and double product (DP = LVSP X HR). The AVDcO2 was unchanged. CSF and myocardial oxygen uptake index (MVO2 = CSF X AVDcO2) were decreased. During atrial pacing, hemodynamic and coronary effects were similar to those seen in the basal state. During the cold pressor test, the increases in LVSP, MAP, and LVEDP were significantly reduced by molsidomine. The variations in CSF and coronary resistance (MAP/CSF) were also significantly different after administration of molsidomine, with better metabolic regulation of the coronary circulation.(ABSTRACT TRUNCATED AT 250 WORDS)
