Most common underlying condition that causes splenic infarct when you do not have sickle cell or heart problem? seemingly healthy 32 yr old female.

Ideas: There are some blood clotting disorders that can be diagnosed by blood tests. Also the arrhythmia atrial fibrillation is a potential source of clots that can be missed if a monitor is not worn for a few weeks. Artery disease not likely at that age unless from a rare inflammatory condition.

Mist common are : Malignant hematologic conditions like leukemia, lymphoma and myelofibrosis; hypercoagulable states like protein s and c deficiency and lupus anticoagulant; autoimmune/collagen vascular disease like systemic lupus erythematosus. These are few of the most common ones. Hope it helpful you.
