The purpose is to exam prospective if simple clinical information in combination with a normal s-procalcitonin are sufficient for exclusion of infective endocarditis (IE).

Biospecimen Retention:   Samples Without DNA

A venous blood sample was obtained from each patients and all samples were centrifuged and immediately frozen.

Enrollment: 761
Study Start Date: March 2007
Study Completion Date: May 2009
IE confirmed IE rejected
Prospective, controlled, blinded study of clinical/TEE criteria of IE compare to clinical/blood test criteria of IE.
IE confirmed IE rejected

Detailed Description:

Despite progress in surgical and medical treatment, infective endocarditis is still associated with high morbidity and mortality.

The variable clinical presentation of IE makes the diagnosis a clinical challenge.

Procalcitonin is a precursor from the hormone calcitonin and also a marker of systemic bacterial infections.

The purpose of this study is:

  • to investigate the diagnostic value of serum procalcitonin (PCT), C-reactive protein (CRP) and sedimentation rate (SR) when IE is suspected.
  • to investigate if a retrospectively generated clinical model suitable for exclusion of IE can be confirmed prospectively.
