Comparison of characteristics of coronary care unit (CCU) patients collected prospectively with those in a retrospective population survey

Prospective CCU patients |
Retrospective CCU patients | |
| Numbers | 89 | 69 |
| Age (streptokinase only); M:F ratio | 63 (62.5); 63:26 | 65 (65); 47:22 |
| 2-150Agent—streptokinase:alteplase | 66:23 | 62:7 |
| 2-150AMI site—inferior:anterior:other | 47:39:3 | 42:22:5 |
| 2-151Median pain to needle time (mean) | 195 (227) | 237 (281) |
| 2-151Median door to needle time (mean) | 80 (88) | 81 (98) |
| Deaths/intracranial haemorrhage | 3/0 | 13/0 |
| Median pain to door time (mean) | 108 (138) | 138 (172) |
↵2-150 Retrospective data are weighted to streptokinase patients, missing most episodes of alteplase use. This excludes a predominantly younger group (less than 70 years) and anterior infarcts (standard eligibility criteria for alteplase at the time), with possibly earlier presentations.
↵2-151 Data calculated on sample of 56 patients only (initial group found by drug alert (streptokinase) + diagnosis of acute myocardial infarction).
AMI, acute myocardial infarction.
