PDT was significantly shorter in the following groups: patients with chest compression pain\/chest discomfort, profuse sweating or dyspnoea than in patients with other symptoms; patients presenting with typical rather than atypical symptoms; patients with pain scores &gt;6 compared with scores \u22646; patients who were aware rather than unaware of AMI symptoms.
