each 0–2 points, total 0–10[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC6005932/) |\n| Risk bands | 0–3 low, 4–6 moderate, 7–10 high[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC6005932/) |\n| MACE by band (Dutch validation, n = 2,440) | 1.7% (0–3), 16.6% (4–6), 50.1% (7–10)[2](https://doi.org/10.1016/j.ijcard.2013.01.255) |\n| Pooled performance for HEART 0–3 | Sensitivity 0.96, NPV 0.99 for short-term MACE[3](https://pubmed.ncbi.nlm.nih.gov/30718010) |\n| Main variants | HEAR score, HEART Pathway, modified HEART score, HEART-2, HEARTS3[4](https://www.cardiologyres.org/index.php/Cardiologyres/article/view/1432/1358) |\n| Introduced | Six, Backus, and Kelder, Netherlands Heart Journal, 2008[5](https://doi.org/10.1007/bf03086144) |\n\n## How it works\n\nEach of the five elements captures a different driver of short-term cardiac risk, and the sum places the patient in one of three bands. The official scoring table assigns History: highly suspicious 2, moderately suspicious 1, slightly or non-suspicious 0; and ECG: significant ST deviation 2, nonspecific repolarization disturbance, left bundle branch block, or pacemaker rhythm 1, normal 0.[6](http://www.heartscore.nl/resources/sixyearsheart3103.pdf) Age scores 0 below 45 years, 1 from 45 to 65, and 2 at 65 or older.[5](https://doi.org/10.1007/bf03086144) Risk factors count conditions including currently treated diabetes mellitus, scored 0 for none, 1 for one or two, and 2 for three or more.[5](https://doi.org/10.1007/bf03086144) • [7](https://www.jstage.jst.go.jp/article/circrep/7/7/7_CR-25-0060/_pdf/-char/en)\n\nThe troponin element has been rescored over time. The original study used AccuTroponin I assays with a positivity threshold of 0.04 ng/ml; subsequent multicenter validation assigned 1 point for a value one to three times the local threshold and 2 points above three times the threshold.[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC6005932/) A total of 0–3 indicates low risk, 4–6 moderate risk, and 7–10 high risk; in the Dutch prospective validation these bands corresponded to 6-week MACE rates of 1.7%, 16.6%, and 50.1%.[2](https://doi.org/10.1016/j.ijcard.2013.01.255) • [1](https://pmc.ncbi.nlm.nih.gov/articles/PMC6005932/)\n\n## How it is done\n\nThe score is calculated at emergency department presentation using the 0-hour troponin value only, together with the initial 12-lead ECG, the clinician's assessment of the history, the patient's age, and cardiovascular risk factor count.[8](https://emj.bmj.com/content/38/11/808) Patients scoring 4–6 warrant consideration of observation and further testing.[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC6005932/)\n\nThe most widely used adaptation, the HEART Pathway, combines the score with serial troponin measurements at 0 and 3 hours after presentation to identify patients eligible for early discharge; a HEART score below 4 with serial troponins defines the rule-out group.[9](https://doi.org/10.1161/circoutcomes.114.001384) • [8](https://emj.bmj.com/content/38/11/808)\n\n## Origin\n\nThe HEART score was introduced by A. J. Six, B. E. Backus, and J. C. Kelder in \"Chest pain in the emergency room: value of the HEART score,\" published in the Netherlands Heart Journal in 2008; the derivation used clinical data from 122 patients referred to the emergency room.[5](https://doi.org/10.1007/bf03086144) A prospective validation by B.E. Backus, A.J. Six, J.C. Kelder, and colleagues followed in the International Journal of Cardiology in 2013, enrolling 2,440 unselected chest pain patients at ten Dutch hospitals.[2](https://doi.org/10.1016/j.ijcard.2013.01.255) The HEART Pathway was evaluated in a randomized trial by Simon A. Mahler, Robert F. Riley, Brian C. Hiestand, and colleagues, published in Circulation: Cardiovascular Quality and Outcomes in 2015.[9](https://doi.org/10.1161/circoutcomes.114.001384) Published accounts do not state the institution where the score was developed, beyond the Netherlands.[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC6005932/)\n\n## Variants\n\nNamed variants reported in the literature include the HEAR score, modified HEART score, HEART Pathway, HEART-2 score, and HEARTS3 score.[4](https://www.cardiologyres.org/index.php/Cardiologyres/article/view/1432/1358) A modified HEART score substituted high-sensitivity cardiac troponin I (Beckman-Coulter enhanced ACCU troponin I) for conventional troponin, identifying 6.8% of patients as low risk at a modified score of 0–2 with a 90-day MACE incidence of 1.1%.[4](https://www.cardiologyres.org/index.php/Cardiologyres/article/view/1432/1358)\n\nRecent adaptations respond to high-sensitivity assays. The high-sensitivity HEART Pathway (hs-HP) uses serial hs-cTnI at 0 and 2 hours (Access 2 assay, [Beckman Coulter](https://www.edgepedia.org/beckman-coulter); 99th percentile upper reference limit 18 ng/L, 10% coefficient of variation at 4 ng/L) and includes a \"one-and-done\" rule-out: patients with a HEAR score of 3 or less, chest pain onset more than 3 hours before presentation, and a single hs-cTnI below 4 ng/L are ruled out for myocardial infarction without serial testing.[10](https://pmc.ncbi.nlm.nih.gov/articles/PMC11697537/) A recalibrated HEART (rHEART) score uses a single high-sensitivity troponin T threshold of 19 ng/L.[11](https://www.ajconline.org/article/S0002-9149%2824%2900594-0/abstract)\n\n## Applications\n\nMeta-analytic performance supports the score's main use, ruling out MACE in low-risk patients. Across 25 studies published from 2010 to 2017 with 25,266 patients, short-term MACE (30 days to 6 weeks) occurred in 2.1% of patients with HEART 0–3 (182/8,832) versus 21.9% of patients scoring 4–10; pooled sensitivity for HEART 0–3 was 0.96 (95% CI 0.93–0.98) and negative predictive value 0.99 (0.98–0.99).[3](https://pubmed.ncbi.nlm.nih.gov/30718010)\n\nHead-to-head comparisons favor HEART over older scores. In the Dutch validation, its c-statistic of 0.83 significantly exceeded TIMI (0.75) and GRACE (0.70) (p < 0.0001).[2](https://doi.org/10.1016/j.ijcard.2013.01.255) At a 25% pretest MACE probability, a HEART score of 3 or less yields a posttest probability of 3.0% versus 7.8% for a TIMI score of 1 or less.[12](https://onlinelibrary.wiley.com/doi/10.1111/acem.13649) Against accelerated pathways, the HEART Pathway classified 38.4% of 4,399 emergency department patients as low risk versus 58.1% by EDACS, but missed fewer events: 30-day MACE occurred in 0.4% of HEART Pathway low-risk patients versus 1.0% by EDACS (p < 0.001).[13](https://heart.bmj.com/content/106/13/977)\n\nExternal validation spans multiple countries and populations: the 2,440-patient Dutch cohort,[2](https://doi.org/10.1016/j.ijcard.2013.01.255) a 939-patient Swedish cohort using 0/1-hour hs-cTnT,[8](https://emj.bmj.com/content/38/11/808) a 2024 US cohort of 821 patients validating rHEART,[11](https://www.ajconline.org/article/S0002-9149%2824%2900594-0/abstract) a 2024/2025 Iranian cohort of 274 patients in which HEART at a cutoff of 3 or less achieved the highest AUC (0.925) against TIMI, GRACE, and EDACS-ADP,[14](https://link.springer.com/article/10.1186/s12873-025-01327-4) and a 2025 Japanese validation confirming the standard scoring table.[7](https://www.jstage.jst.go.jp/article/circrep/7/7/7_CR-25-0060/_pdf/-char/en)\n\n## Limitations and alternatives\n\n**Reproducibility is imperfect.** Both the HEART score's history component and emergency physicians' assessment of chest pain history show kappa values of only about 0.6 or higher for interobserver agreement.[8](https://emj.bmj.com/content/38/11/808) A 2021 study by Soares and colleagues found 78% interrater agreement between attendings and residents, with the most discrepancies in the history component.[15](https://www.ochsnerjournal.org/content/early/2025/04/30/toj.24.0108/tab-figures-data) The HEART Pathway decision support algorithm addresses this by replacing subjective components with objective binary inputs.[10](https://pmc.ncbi.nlm.nih.gov/articles/PMC11697537/)\n\n**The troponin component appears underweighted.** In 15 Kaiser Permanente Southern California community emergency departments, the 30-day death or myocardial infarction rate for low-risk scores of 0–5 was 0.4% overall, but a troponin component of 1 point carried a 2.7% risk (95% CI 1.7–4.1), at least triple any other component; among 135 encounters with 30-day MI or death, 83% had an index troponin within normal limits.[16](https://www.ovid.com/journals/jacepo/fulltext/10.1002/emp2.12315~not-all-heart-scores-are-created-equal-identifying-lowrisk) The authors suggest allocating additional points to troponin and recalibrating the cutoff.[16](https://www.ovid.com/journals/jacepo/fulltext/10.1002/emp2.12315~not-all-heart-scores-are-created-equal-identifying-lowrisk)\n\n**Assay sensitivity changes the score.** The fifth-generation ultra-high-sensitivity troponin assay in current use is up to 100-fold more sensitive than the assay in the original 2008 study, which can shift low-risk patients into higher-risk categories.[4](https://www.cardiologyres.org/index.php/Cardiologyres/article/view/1432/1358)\n\nMissed events occur even in well-performing cohorts: in the Swedish 0/1-hour hs-cTnT analysis, the HEART score alone ruled out 53.4% of patients with an NPV of 98.8% and sensitivity of 94.8% for 30-day MACE, missing six patients (four MI, one unstable angina, one cardiac arrest).[8](https://emj.bmj.com/content/38/11/808) Published studies do not quantify HEART performance in renal disease or troponin elevation from explicitly non-ACS causes.[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC6005932/)\n\n## References\n\n1.
