The prehospital course of patients with chest pain

摘要: Abstract In order to determine whether prehospitalization characteristics of patients with chest pain are useful in predicting their subsequent course, we analyzed the precoronary care course 211 consecutive admitted because suspected myocardial infarction. On basis serial electrocardiograms and enzymes, 61 had a definite infarction on admission, 30 evolved criteria for an during hospitallzation, 102 cardiac without infarction, 18 were judged have noncardiac pain. The mean patient delay from onset arrival at hospital was 456 ± 703 minutes (median 210 minutes). decision seek medical help consumed 307 575 this delay, whereas transportation required only 17 49 minutes. Known heart disease, known stable angina progressive unstable tended prolong patient's help. Of 140 who contacted physician, 67 (48 per cent) sent emergency room; 71 additional 180 436 38 minutes) physician-advised consisting office visits (59 patients), house call (five patients) other attempted therapy (seven patients). presence prodromas or consistent not significantly different any group. We conclude that prodromas, although common, helpful differentiating those among hospitalized Furthermore, over 6 hours median 3 12 indicates is most immediate problem be solved decrease out mortality.
