What are the recommendations for risk stratification in patients with non ST-elevation acute coronary syndromes (NSTE-ACS)?
The recommendations for risk stratification in patients with NSTE-ACS include performing rapid determination of likelihood of ACS, including a 12-lead ECG within 10 minutes of arrival at an emergency facility; performing serial ECGs at 15- to 30-minute intervals during the first hour in symptomatic patients with initial nondiagnostic ECG; measuring cardiac troponin (cTnI or cTnT) in all patients with symptoms consistent with ACS; measuring serial cardiac troponin I or T at presentation and 3-6 hours after symptom onset in all patients with symptoms consistent with ACS; using risk scores to assess prognosis in patients with NSTE-ACS; obtaining supplemental electrocardiographic leads V7 in patients with initial nondiagnostic ECG at intermediate/high risk for ACS; and considering BNP or NT pro-BNP to assess risk in patients with suspected ACS.
