In patients with truly time-sensitive disease (defined in the 2014 ACC/AHA guidelines as needing to proceed in 2–6 weeks), DAPT can be stopped 3 (three) months (90 days) after a coronary stent is placed if postponing surgery any longer would result in significant morbidity.
Dual antiplatelet therapy (DAPT) is recommended for 1 month following bare metal stent placement, for 3 months following a second generation drug-eluting stent placement, and for 6–12 months following a first generation drug-eluting stent placement. [1] DAPT's antiplatelet properties are intended to prevent blood clots, however they also ...
[1] [2] As a result, dual therapy stents were developed to reduce the long-term need for dual-antiplatelet therapy. [3] The COMBO stent is the first and only dual therapy stent that addresses the challenges of vessel healing in drug-eluting stents. [4] This stent is an anti-CD34 antibody-coated and sirolimus-eluting bioresorbable stent. [2]

“The public should know that aspirin remains an important treatment for a heart attack, and in these studies, it was an essential therapy in the 3 months after receiving the stent,” Dr. Harlan ...
Before-and-after cross sections of the artery show the results of the stent placement. Arterial Stenting 3D Medical Animation Cardiac stenting is achieved by PCI procedures in two distinct medical situations, when a patient has clearly suffered a heart attack and therefore PCI/stenting is being used in an emergency setting, termed 'primary PCI'.
[4] [5] The reduction in death, however, does not persist long-term. After a few years, the survival after repair is similar to EVAR or open surgery. This observation may be the result of durability problems with early endograft, with a corresponding need for additional procedures to repair endoleaks and other device-related issues.
Most current FDA-approved drug-eluting stents use sirolimus (also known as rapamycin), everolimus and zotarolimus. Biolimus A9-eluting stents, which utilize biodegradable polymers, are approved outside the U.S. [27] Newer-generation PCI technologies aim to reduce the risk of late stent thrombosis or other long-term adverse events.
