Abstract

In practice, TTC is diagnosed almost exclusively either via (1) emergency cardiac catheterisation, primarily for apparent 'STEMI', or (2) recognition of a potentially precipating stress, primarily in patients with a non-ST-elevation (N-STE) ECG pattern. We therefore hypothesized that the greatest delays in diagnosis would occur in the subgroup with N-STE and no known stressor. A seasonality analysis was also undertaken, to test a possible association between heat stress and TTC.
