Why stroke is more common than pulmonary embolism in patients with atrial fibrillation?

Atrial fibrillation (AF) is the most common cardiac arrhythmia, affecting >33 million individuals worldwide, and both the incidence and prevalence of AF are increasing.The apparent association between AF and PE may be attributable to shared risk factors, induced by factors related to AF itself (eg, intracardiac thrombi), or mediated by stroke or stroke‐related complications secondary to AF. The brain needs blood and oxygen. When that doesn’t happen and that crucial nourishment can’t reach the brain — either because of a clogged artery or a burst vessel — brain cells start to die.High blood pressure is generally considered the most common controllable risk factor for stroke, but atrial fibrillation is the most powerful. Evidence infers that the apparent risk of PE by AF could be explained by intermediate development of IS(Ischemic Stroke). Clinical and observational studies, including this study, have shown that AF is associated with risk of IS and that patients with IS are at a high risk for venous thrombosis

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,...

LASIK procedures have become more accessible and much more common in recent years. Many patients are attracted to the idea of LASIK, as it can eliminate the need for glasses or contact lenses. Research LASIK and the associated risks and benefits. For your original post, choose one of the vision problems that can be corrected by LASIK. Discuss how this problem affects the physiology vision and how LASIK can be used to correct this problem.
