Key result
T wave positivization only in unstable angina was associated with a lower incidence of hospital myocardial infarction compared to additional ST segment elevation (6.24% vs 31%; P<0.02).
Why the study?
Does the electrocardiographic pattern of T wave positivization only compared to additional ST segment elevation predict in-hospital prognosis in patients with unstable angina?

T-wave positivization may identify lower-risk unstable angina; leaves open prospective validation for ECG-guided risk stratification.
Cohort (n=59)
Does the electrocardiographic pattern of T wave positivization only compared to additional ST segment elevation predict in-hospital prognosis in patients with unstable angina?
Absolute Event Rate: 6.24% vs 31%
p-value: p=<0.02
Patients with unstable angina presenting with T wave positivization only have a more favorable in-hospital prognosis and more developed collateral circulation compared to those with additional ST segment elevation.
Lewin et al. (1987) conducted a cohort in Unstable angina pectoris (n=59). T wave positivization only vs. T wave positivization with additional ST segment elevation was evaluated on hospital myocardial infarction (p=<0.02). T wave positivization only in unstable angina was associated with a lower incidence of hospital myocardial infarction compared to additional ST segment elevation (6.24% vs 31%; P<0.02).
