Figure 2 Comparison of the outcomes of primary percutaneous transluminal coronary angioplasty (PTCA) in the 231 patients in our series who had acute myocardial infarction with ST segment elevation but without cardiogenic shock with a similar population of 245 patients undergoing primary PTCA in the Primary Angioplasty Registry (25), which required ST segment elevation and excluded patients with shock. The median times from emergency department (ED) arrival to reperfusion and the rates of PTCA success, reinfarction, stroke or transient ischemic attack (TIA), and in-hospital mortality were similar in the two groups. Black bars: Exeter and Portsmouth primary PTCA patients presenting with ST elevation without shock (n = 231). White bars: Primary Angioplasty Registry PTCA patients (n = 245).
