How does atrial fibrillation contribute to the development of aCVA?

Solutions

Expert Solution

AF (atrial fibrillation) is a complex arrhythmia characterised by both abnormal automatic firing and the presence of multiple re-entry circuits looping around the atria.

It's the most common arrhythmia and causes irregularly irregular pulse.

How does AF cause CVA ?

Fibrillation causes blood to

stagnate in the left atrial

appendage.(since there is no effective contraction,it causes stagnation of blood)

The stagnant blood creates an

environment for a thrombus or

blood clot to form

The clot dislodges from the

Left atrial appendage and travels through

arterial system

The clot lodges itself in the blood

vessels of the brain, restricting or blocking

blood flow and causing a stroke

There is a CHADSVAS score to predict risk of stroke in AF

C - Congestive cardiac failure -1

H-Hypertension

Age more then 75 -2

Stroke -2

Vascular events

Age 65 to 75 -1

Sex (female ) 1

A score more than 6 will have a 99% chance of stroke

Score 1 needs aspirin prophylaxis

Score 2 and above needs oral anticoagulant

Atrial fibrillation is the most common dysrhythmia treated in the US. Warfarin, enoxaparin, and rivaroxaban are all used at-home care for patients who have or at risk of developing atrial fibrillation. A) Why are the most commonly used medications for treating patients with a-fib not antidysrhythmic drugs (i.e., they are not intended to alter the rhythmicity of the heart)? B) What are the notable differences in patient education a nurse should provide to patients discharged with prescriptions for warfarin, enoxaparin,...
