- To improve the prognosis in patients with acute myocardial infarction (AMI) if treatment by early instituting treatment, we initiated a media campaign during 1 year with the intention to reduce delay times and increase ambulance use in patients with acute chest pain. This article describes the outcome during 3 years after the campaign was finished. The median delay time in patients with AMI was reduced from 3 hours 0 min before the campaign to 2 hours 20 minutes during the year of the campaign (P < .001). The median delay time remained at a similar level (2 hours 20 min) during the 3 years after the campaign. Ambulance use was not affected during or after the campaign. It can be concluded that a media campaign resulted in a reduction of delay times not only during the campaign, but also during 3 years after its performance, whereas ambulance use was not affected.

- Since 1980 an Emergency Medical Service (EMS) system with a two-tier ambulance service has been operating in Göteborg. During this 12-year period, all cardiac arrests outside hospital have been monitored. Cardiopulmonary resuscitation (CPR) training for the general public began in 1985 and, by the end of 1992, 125 000 persons had been trained. The aim of this study was to define the factors associated with an increased chance of survival after cardiac arrest witnessed out-of-hospital and secondary to ventricular fibrillation. The study group comprises all patients with cardiac arrest witnessed outside hospital in Göteborg between 1980 and 1992, in whom CPR was initiated by our EMS and ventricular fibrillation observed at the first ECG recording. In a multivariate analysis of age, sex, time of collapse, interval between collapse and first defibrillation, bystander-initiated CPR, the following factors were associated with an increased chance of being discharged from hospital: (1) Short interval between collapse and first defibrillation (P < 0.001); (2) Bystander-initiated CPR (P < 0.001); and (3) Age (P < 0.05). Among patients with an out-of-hospital cardiac arrest who were found by the EMS personnel to have ventricular fibrillation, the predictors of survival were: interval between collapse and defibrillation, bystander-initiated CPR and age.

- We studied 921 consecutive patients admitted to a single hospital for acute myocardial infarction during a period of 21 months and related their prognosis to gender. Women (n = 300, 33%) were on average 7 years older (p < 0.001) and more frequently had a previous history of hypertension (p < 0.001) and congestive heart failure (p < 0.001) than did men. They also tended to delay longer in seeking medical treatment and more often presented with only vague symptoms (p < 0.05). The in-hospital mortality for women was 19% versus 12% for men (p < 0.01). Women more often showed signs of congestive heart failure (p < 0.05) despite smaller infarcts as estimated from enzyme levels (p < 0.05). Total mortality during 1 year was 36% in women and 25% in men (p < 0.01). In a multivariate analysis, female gender did not appear as an independent risk factor for death. During 1 year of follow-up no differences in morbidity were observed between the sexes. We conclude that if women fare worse than men after suffering an acute myocardial infarction, the increased mortality is accounted for by older age.
