In most studies, aspirin has been shown to be effective for a period of 1 year in reducing the frequency of saphenous vein bypass graft occlusion when begun 1 day before surgery, on the day of surgery, or the day after surgery. Effective doses of aspirin range from 100 to 975 mg/d. Aspirin in combination with dipyridamole is effective in the prevention of saphenous vein bypass graft occlusion i...

Communications to the Editor local vasodilator and reduces platelet aggregation in vitro; it is believed to mediate dipyridamole’s in moo antiplatelet and vasodilator effects. It is unclear how methylxanthines cause bronchodilation; almost all act to block adenosine receptors. Aminophylline has been shown to reduce cerebral blood flow, probably by antagonizing the vasodilator effects of adenosi...

BACKGROUND AND PURPOSE Trial data suggest that dipyridamole, with or without aspirin, is more efficacious in the secondary prevention of stroke than of coronary events. This selective effect might be attributed to blood pressure lowering by dipyridamole. Therefore, we aimed to assess the effect on blood pressure in the setting of a randomized clinical trial in patients with cerebral ischemia of...

BACKGROUND Increasing evidence suggests that beyond its antiplatelet properties, dipyridamole may have pleiotropic effects on other cells within the neurovascular elements of the brain. In this experimental cellular study, we asked whether dipyridamole can ameliorate brain endothelial injury after exposure to inflammatory and metabolic insults. METHODS Human brain endothelial cells were grown...

Dipyridamole is an effective inhibitor of cardiovirus growth in cell culture. The effects of dipyridamole on mengovirus replication in vivo and in vitro were examined in the hope the drug could be used as an experimental analog of the poliovirus inhibitor guanidine. Guanidine selectively inhibits poliovirus RNA synthesis but not RNA translation, and as such, has been a valuable research tool. A...

We investigated the effect of i.v. dipyridamole, a potent small-vessel coronary vasodilator, on myocardial infarct size in conscious dogs. Dipyridamole, 7-9.7 microgram/kg; 15 dogs) or saline (15 dogs) was infused for 6 hours beginning 10 minutes after acute permanent occlusion of the mid-circumflex coronary artery. After sacrifice, 48 hours after occlusion, stereoscopic postmortem angiography ...

The effects of 0.25 mg/kg dipyridamole on left ventricular (LV) pressures, LV dP/dt, heart rate, aortic pressures, left circumflex coronary blood flow, and left circumflex coronary arterial diameters and on calculations of late diastolic coronary resistance and large coronary cross-sectional area were studied in 15 conscious dogs. Injection of dipyridamole, a drug that has a mechanism of action...

AIM AND BACKGROUND Dipyridamole-induced stress myocardial perfusion scans (MPS) has been widely used for management of coronary artery disease. The adverse effects of dipyridamole and other stress agents have been evaluated. The aim of this research is to confirm the dynamic data on dipyridamole side effects during MPS. METHODS We collected data of 183 patients who underwent dipyridamole-indu...
