Apr 04,  · e following are key points to remember from is review about e use of dual antiplatelet erapy (DAPT) for post-percutaneous coronary intervention (PCI) patients undergoing noncardiac surgery: A significant number of patients following coronary stenting undergo noncardiac surgery and require DAPT interruption. Zebrafish care. AB, alpha-actin-GFP, and RGYn fish strains were maintained under standard conditions at 28.5°C on a -hours dark and 14-hours light cycle (Higashijima et al., 1997. Westerfield, 2000). e RGYn fish utilize retinoic acid response element (RARE) driven promoters to express EYFP (Perz-Edds et al., 2001).To work wi embryos at e desired developmental stage, zebrafish tanks. Our finding suggests no apparent benefit but instead harm wi extension of DAPT beyond 1 year after stenting wi DES when no event has occurred wi in e first year after stenting. No conclusion can be drawn for high-risk patients who could not be randomised. e consistency between findings from all trials of such interruption suggests e need for a reappraisal of guidelines for DAPT. 25,  · isions regarding treatment wi and duration of DAPT require a oughtful assessment of e benefit/risk ratio, integration of study data, and patient preference. Recommendations in e document apply specifically to duration of P2Y 12 inhibitor erapy in patients wi CAD treated wi DAPT. Aspirin erapy should almost always be continued. Findings Nine patients taking DAPT for up to 3 mon s, and 12 taking DAPT between 9 and 12 mon s participated in e focus groups. We found at: (1) participants adhered to treatment when ey believed DAPT was important to heal outcomes. (2) ose who experienced nuisance bleeding reported symptoms to be mild and manageable.
