Aspirin for MI/angina

162-325 mg of chewable aspirin should be promptly administered to patients who do not have bleeding tendency. Administration should not be delayed as the peak effect of aspirin can be seen as early as half hour after administration and it is important to prevent thrombus formation and propagation.

If the patient undergoes stenting 162-325 mg aspirin should be continued for 1 month after bare metal stent implantation, 3 months after sirolimus-eluting stent implantation, or 6 months after paclitaxel-eluting stent implantation.

Most subjects will get low dose (75-162 mg) all their life.
