Two hundred and thirty-four patients admitted to a coronary care unit (CCU) were interviewed a few days after arrival in hospital to determine reasons for patient delay and the various components of total delay time from onset of symptoms to arrival in CCU. Of the three major components of delay, decision time (time from onset of symptoms to decision to go(More)
A media campaign conducted to reduce delay time and to increase the use of ambulance transport in acute myocardial infarction was performed in an urban area with about half a million inhabitants during 1 year. The main message was that chest pain lasting more than 15 minutes might indicate acute myocardial infarction; dial 90,000 immediately for ambulance(More)
In order to reduce the delay times from onset of symptoms to arrival in hospital, and increase the use of ambulance in patients with suspected acute myocardial infarction (AMI), a media campaign was initiated in an urban area. An initial 3-week intense campaign was followed by a maintenance phase of 1 year. Delay times and ambulance use during the campaign(More)
In a randomized, double-blind study, rt-PA vs. placebo treatment in early suspected acute myocardial infarction (AMI) was evaluated in patients both in hospital and prehospitally. The inclusion criteria were as follows: (a) age less than 75 years; and (b) chest pain indicative of AMI, of no longer than 2.75 h duration before first examination. In the(More)
We evaluated the effect of a media campaign aimed at reducing delay times in suspected acute myocardial infarction (AMI) on the volume of chest pain patients seen in the emergency department. During the 1st week of the campaign, the mean number of chest pain patients increased from 10.5 per day prior to the start to 25.4. However, the number declined(More)
We investigate whether symptoms of pressure, tightness, and/or pain in the chest, neck, and/or throat after administration of the 5HT1B/1D agonist avitriptan were associated with objective impairment of the myocardial function on 12-lead electrocardiogram (ECG), continuous ECG (Holter) monitoring, and echocardiography. Migraine sufferers who in two-thirds(More)
Independent trials of early administration of beta-blockers and thrombolytic agents have shown beneficial effects on both short- and long-term prognoses in acute myocardial infarction (AMI). The effects of a combination of the two strategies have not been thoroughly documented. Three hundred and fifty-two patients, of less than 75 years of age, with chest(More)
In a randomized, double-blind study, in which recombinant tissue plasminogen activator (rt-PA) administered at an early stage was compared with placebo in patients with suspected acute myocardial infarction (AMI), the effects on pain were studied in 312 patients. Inclusion criteria were as follows: (a) chest pain of duration less than 2 h and 45 min; and(More)
