A patient with fever, subungual hemorrhages, Osler nodes, and heart murmur most likely has what condition?

• A. Bacterial Endocarditis.
• B. Rheumatic fever.
• C. Viral myocarditis.
• D. Pericarditis.

Answer: (A)

Fever with peripheral findings on the fingers and a new or changing heart murmur points to infective endocarditis. The subungual hemorrhages (splinter hemorrhages) and Osler nodes are classic peripheral manifestations of this infection, reflecting vascular and immune complex–mediated processes linked to vegetations on heart valves. The fever signals systemic infection, and the heart murmur indicates valvular involvement from those vegetations.

Rheumatic fever can cause a heart murmur and systemic symptoms but typically presents with migratory polyarthritis, not these specific nail and finger nodules. Viral myocarditis mainly causes chest pain, fatigue, and cardiomyopathy without these peripheral stigmata. Pericarditis presents with chest pain worsened by lying flat and a pericardial rub, rather than Osler nodes or splinter hemorrhages.
