Comparative Study[Utility of BNP measurement in the emergency room in patients with suspected unstable angina with a normal ECG].
Unstable angina is a serious condition, difficult to diagnose in the emergency room. Clinical, electrocardiographic and biological signs (increased troponine) are not sensitive. The authors set out to assess whether measuring B natiuretic peptide in the emergency room was more sensitive for identifying symptomatic coronary lesions. ⋯ All patients underwent coronary angiography during their hospital admission. The sensitivities of troponine at a threshold of 0.4 ng/ml and of brain natiuretic peptide (BNP) at a threshold of 10 pg/ml in this population were 66% and 92% respectively. The use of troponine and BNP together provided better results than troponine and BNP alone for the identification of patients with chest pain with significant coronary lesions.
