Background: not a single clinical shift passes without evaluation of at least one patient with chest pain.this chief complaint accounts for 6.5 million visits per year and is the second most common presenting symptom to the emergency department (ed). 1 additionally, there is substantial liability associated with missed coronary artery disease, accounting for the highest proportion of paid. Intermediate heart score (4 – 6) = 16.6% mace rate. high heart score (7 – 10) = 50.1% mace rate. c statistic of heart score (0.83) > timi (0.75) > grace (0.70) limitations: study performed on patient population from the netherlands. observational study. each ed had different cut off values for positive troponins.

The heart score was developed in an ed setting in all patients with chest pain and not just acs patients. a larger, prospective study with narrower confidence intervals in a us population would be nice, but best current evidence is that the heart score performs better than timi and grace scores. 1. backus b, six a, kelder j, gibler w, moll f. 24% of all patients reached one or more of above endpoints. average heart score for all patients that did not reach an endpoint: 3.71 1.83. average heart score for all patients that did meet an endpoint: 6.51 1.84. significant difference p < 0.0001. Heart score with hs troponins lowers the number of low risk patients from 40% to 10% and 30 day mace rate lowers from 1.5% to 0.9%. if you add a second troponin at 2 or 3 hours, the mace rate falls to 0.3% [31]. heart pathway is most useful for low medium risk patients.

Backus et al current cardiology reviews 2011 –> c statistic = heart 0.9 vs timi 0.65 [5] the heart score is more accurate than timi and specifically outperforms timi at “low risk” thresholds; now lets talk about the heart score. a heart score of 0 – 3 is considered low risk, but there are some very important caveats to this:. The score is an acronym for history, ekg, age, risk factors, and troponin. unlike other clinical decision rules, the components are scored 0, 1, or 2, allowing for a middle ground, and this cdr was uniquely developed for use in the ed. this research group has previously performed prospective validation studies assessing the heart score.
