Prognosis

The risk is increased with:

• Infected prosthetic valve  ^a
• Systemic embolisation  ^b
• Staphylococcus aureus infection  ^b
• Neurological complications  ^c

Note:

• Two-thirds of patients with prosthetic valve infective endocarditis die ^a

Neurological complications increase the risk of dying from infective endocarditis

Patient	Prognostic Factor	Outcome	CER	RR (95% CI)	NNF+ (95% CI)
infective endocarditis c	neurological complication not independent	death at 3 months	56%	1.31 (1.09 to 1.57)	6 (3 to 19)
