Why the study?
Does maximum ST-vector magnitude during the first 24 hours of vectorcardiographic monitoring predict death or non-fatal myocardial infarction in patients with suspected unstable angina pectoris?
Does maximum ST-vector magnitude during the first 24 hours of vectorcardiographic monitoring predict death or non-fatal myocardial infarction in patients with suspected unstable angina pectoris?
Maximum ST vector magnitude during the first 24 hours of vectorcardiographic monitoring is a strong independent predictor of 1-year death or non-fatal myocardial infarction in patients with unstable angina.

May refine risk stratification in unstable angina; extends ECG observations but remains hypothesis-generating pending prospective validation.
Abrahamsson et al. (1999) studied this question.
