Can the HEART Score Rule Out Acute Coronary Syndromes in the ED?

Nine studies, comprising 11,217 patients, were included for meta-analysis. Major adverse cardiac event prevalence was 15.4% (95% confidence interval [CI] 14.8% to 16.1%) at a mean follow-up of 6 weeks. In the low-risk group (HEART score of 0 to 3), a combined total of 1.6% of patients (95% CI 1.2% to 2.0%) had an incidence of major adverse cardiac event. The pooled sensitivity and specificity of the HEART score for predicting major adverse cardiac events were 96.7% (95% CI 94.0% to 98.2%) and 47.0% (95% CI 41.0% to 53.5%), respectively (Table).
