World Stroke Day 2023 - Quiz

If a patient with newly diagnosed atrial fibrillation has high bleeding risk (e.g.HAS-BLED score >3), which of the following is the best treatment option as far as the anticoagulation therapy is concerned?
A) Withhold the anticoagulation therapy to modify the bleeding risk factors.
B) Administrate anticoagulation agents only when the HAS-BLED<3.
C) Administrate anticoagulation therapy immediately and try to modify the bleeding risk factors.
D) Bleeding risk factors and scores should not guide the decision for the initiation of the anticoagulation therapy
E) High bleeding risk and recent medical history of gastrointestinal bleeding are absolute contraindications to anticoagulation therapy.
According to the guidelines, which is the best anticoagulation agent for AF patients at high bleeding risk?
A) Vitamin K antagonists
B) Non-Vitamin K antagonists
C) Low molecular weight heparin
D) Unfractionated Heparin
E) Fondaparinux
Which of the following is correct?
A) Estimated bleeding risk, in the absence of absolute contraindications to OAC, should not in itself guide treatment decisions to use OAC for stroke prevention.
B) Stroke and bleeding risk reassessment at periodic intervals is not recommended to inform treatment decisions (e.g. initiation of OAC in patients no longer at low risk of stroke) and address potentially modifiable bleeding risk factors
C) In high bleeding risk patients, clinical pattern of AF (i.e. first detected, paroxysmal, persistent, long-standing persistent, permanent) should guide the thromboprophylaxis management.
D) Rhythm control therapy is indicated in all paroxysmal AF patients at high bleeding risk in order to prevent the AF recurrences.
