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.
