<human>: Hello.  I am a 39 year old male with a history of heart disease on both sides of my family.  I have had an elctro-physiology study done.  That was about 8 years ago.  Over the past few months i have been seeing splinter hemorrrhages on my thumbnails and big toe nails.  My body seems to ache for no apparent reason.  I went to see my doctor about this earlier this summer.  He wasnt overly concearned but I had some lab work completed.  Of the five blood tests done, only my white blood count was abnormal.  It was low.  I do not smoke.  I consider myself to be active enough to maintain a healthy lifestyle.  Should I be concerned?  Thank you.
<bot>: Hi, Thanks for asking. Based on your clinical history and query, my opinion is as follows:1. Splinter hemorrhages in previous heart disease, strongly need to rule out infective endocarditis.2. However, looking at the associated low white cell count, do get a blood culture.3. Echocardiogram of the heart is also necessary to look for any vegetation. Discuss with your doctor regarding this test. Hope it helps. Any further queries, happy to help again.
