Secondary prevention of stroke: does dipyridamole add to aspirin?
Aspirin used alone reduces secondary occurrence of vascular events in cerebrovascular patients. There is no evidence, however, of a reduction of fatal events (vascular deaths and fatal strokes). In contrast, aspirin in combination with dipyridamole reduces non-fatal as well as fatal events. These results as well as the indirect comparisons of the risk reductions suggest that the combination of aspirin with dipyridamole may be superior to aspirin alone; this hypothesis is presently tested in a large randomized trial.
This study reports significant associations of genetic variants in TNFA and IL6 with the risk for AITD, highlighting the relevance of polymorphisms in inflammation-related genes in the etiopathogenesis of AITD.
