The ESPS-2 showed that dipyridamole alone prevents stroke. More importantly, it showed a substantial benefit for dipyridamole combined with aspirin over aspirin alone. When the ESPS-2 data are aggregated with the 14 previous trials of dipy ridamole combined with aspirin over aspirin alone, the combination reduces the risk of stroke by 23% over aspirin alone. Nevertheless, important questions remain unanswered. We conclude that another randomized clinical trial showing a significant benefit of the combination of dipyridamole plus aspirin over aspirin alone may be needed before the addition of dipyridamole to aspirin is widely accepted for prevention of stroke. |
