Which cardiovascular condition is associated with systemic lupus erythematosus (SLE)?

Pericarditis is the cardiovascular condition most commonly associated with systemic lupus erythematosus (SLE). This inflammatory process involves the pericardium, which is the fibrous sac surrounding the heart. SLE can lead to inflammation of various structures, and the pericardium is particularly vulnerable due to the systemic nature of the disease and the immune-mediated damage it causes.

In the context of SLE, pericarditis may present as chest pain, which can be sharp and worsens with inspiration or coughing. This condition occurs due to the autoimmune attack on the connective tissues of the pericardium, leading to the accumulation of fluid and potentially causing complications like pericardial effusion.

In addition to pericarditis, SLE is associated with a range of other cardiovascular complications, but pericarditis is the most directly linked and frequently observed in patients. Thus, this makes it the correct answer, highlighting the need for clinicians to monitor for this condition when treating patients with SLE.
