Clinical Case 1

• 72 year old woman with NSTEMI, permanent atrial fibrillation and elevated CHADSVASC score of 3 on a non-vitamin K antagonist develops exertional angina. A stress test is abnormal with high risk features. Coronary angiography demonstrates severe proximal LAD disease and she is treated with a drug eluting stent.

Atrial Fibrillation Recommendations

1. Double therapy is preferred to triple therapy to reduce hemorrhagic complications without a signal of harm with regards to stent thrombosis.

2. Non-vitamin K antagonists are preferred to warfarin and should be used at doses which are effective to reduce systemic thromboemboli.

3. Patients on double therapy all start on triple therapy for a period of at least periprocedurallyto one month.

4. Reasonable to stop antiplatelet tx at one year.

Summary

1. Bleeding is a common occurrence and is associated with excess morbidity and mortality.

2. Antiplatelet therapy including DAPT is no longer a 12 month standard answer post ACS.

3. Double therapy in patients with Afib should include triple therapy for the first week to minimize stent thrombosis and maybe to one month. Double therapy should be the default and triple therapy should be avoided.

4. Abbreviated DAPT lowers bleeding without signal of excess risk of MACE
