BACKGROUND: Fast and accurate chest pain risk stratification in the emergency
department (ED) is critical. The HEART score predicts the short-term incidence of
major adverse cardiac events (MACE) in this population, dividing it in three risk
categories. We aimed to describe the population with chest pain, to characterize
the subgroup of patients with acute coronary syndrome (ACS) and to assess the
prognostic value of Manchester triage system and of HEART score. METHODS:
Retrospective observational study including patients admitted to the ED of a
tertiary hospital with chest pain as the presenting symptom. The primary outcome
was a composite of all-cause mortality, myocardial infarction or unscheduled
revascularization at 6 weeks. RESULTS: We enrolled 233 patients (age 58?±?19;
55.4 % males). The most common final diagnosis was non-specific chest pain
(n?=?86, 36.9 %), followed by ACS (n?=?22, 9.4 %). Male gender, smoking and
chronic kidney disease were associated with higher risk of ACS. According to
Manchester triage system, chest pain patients stratified with red or orange
priority had a higher incidence of ACS (16.5 % vs. 3.8 %, p?=?0.006). The
application of HEART score showed that most patients were in low risk category
(56.3 %). The six-week incidence of MACE in each category was 2 %, 15.6 % and
76.9 % (p?0.001). HEART score accurately predicted the short-term incidence of
MACE in chest pain patients (c-statistic 0.880; 95 % CI, 0.807-0.950, p?0.001).
CONCLUSIONS: Chest pain patients have very different levels of severity and the
discriminatory power of Manchester triage system should be used in the assessment
of this population. The HEART score seems to be an effective tool for risk
stratification in the ED.
