Which statement about atrial fibrillation (AFib) is true?

Atrial fibrillation (AFib) is a complex condition with a well-documented genetic component, making the statement about a variety of different genes contributing to its expression accurate. Research has shown that multiple genes are involved in the pathophysiology of AFib, indicating a polygenic influence rather than the effect of a single gene. This multifactorial genetic basis implies that various genetic variations can affect the electrical conduction system of the heart, leading to AFib.

In addition to genetic factors, various environmental influences such as lifestyle and comorbid conditions can also play a significant role in the development of AFib, underscoring the complexity of this arrhythmia. The presence of various genes means that individuals may inherit differing susceptibilities to AFib, which can manifest in different forms and severities.

Understanding this genetic basis is crucial for nursing practice as it can influence prevention strategies, risk assessments, and patient education. It opens the door to more personalized approaches in managing patients who may be at higher risk for AFib due to their genetic profiles.
