Reliability using the universal classification of acute myocardial infarction compared to ST-segment classification.

Objectives: To study the inter-physician reliability using the universal classification (UC) of acute myocardial infarction (AMI) compared to the ST-segment classification (STC). The UC is based on clinical, electrocardiographic (ECG), and pathophysiologic characteristics compared to the STC, which is mainly ECG based.

Methods: In this registry of consecutive patients with AMI presenting to a tertiary hospital, we studied the inter-physician reliability [weighted kappa (wK)] using the UC and the STC.

The universal classification is an independent predictor of long-term outcomes in acute myocardial infarction.

Background: The long-term outcomes of patients with acute myocardial infarction (AMI) according to the universal classification (UC) are unknown. We investigated whether the outcome of these patients is better predicted by the UC than the ST-segment classification (STC).

Methods: We conducted a retrospective study of 348 consecutive patients with AMI with mean follow-up of 30.

Quartiles of peak troponin are associated with long-term risk of death in type 1 and STEMI, but not in type 2 or NSTEMI patients.

Background: The prognostic value of peak cardiac troponin (cTn) in different types of acute myocardial infarction (AMI) under the universal clinical classification is unknown.

Hypothesis: We tested the hypothesis that the prognostic value of cTn varies with its peak level and type of AMI.

Methods: We studied 345 consecutive patients with AMI with mean follow-up of 30.
