New scoring system for acute chest pain risk stratification: Is it worth SVEAT-ing it?

Table 1 Summarizing differences between the HEART and SVEAT scores

Scoring variables	HEART score	SVEAT score
Symptom- Chest pain	Stratifies symptoms subjectively, i.e., based on level suspicion. (This is open to bias based on the provider)	Stratifies symptoms more objectively by using well-defined terminologies for chest pain, hence being less open to bias
Risk factor	Includes hyperlipidemia, hypertension, diabetes mellitus, smoking, and a family history of obesity, and scoring is based on their frequency. Does not take recent coronary disease into account	Includes recent myocardial infarction, PCI/CABG, or any prior vascular event
EKG	Positively scores any EKG changes. If none are present, score 0. No negative scores	Gives a score of 3 for dynamic ST or T wave changes, higher than HEART (2). It also assigns a negative score when there are no EKG changes in the presence of ongoing chest pain
Age	Assigns a score of 2 for all patients over 65 yr	Assigns a score of 2 for all patients over 75 yr. It also assigns a negative score when the patient is < 30 yr
Troponin	Is applicable for both Troponin I and T assays. No negative scores for a normal Troponin	Validated for the 4th generation ultra-sensitive Troponin I assay only. Assigns negative scores for normal Troponin levels after > 4 h of chest pain

CABG: Coronary artery bypass grafting; EKG: Electrocardiographic; PCI: Percutaneous interventions; ST: Subthemes; SVEAT: Symptoms, history of Vascular disease, Electrocardiography, Age, and Troponin; HEART: History, Electrocardiography, Age, Risk factors and Troponin.
