- We randomized 352 patients with suspected acute myocardial infarction (AMI) to treatment with rt-PA (n = 177) or placebo (n = 175). Patients were eligible if evaluated within 2 h and 45 min from onset of chest pain, and if aged less than 75 years. There were no ECG criteria for inclusion. A mobile coronary-care unit with a cardiologist present was used to initiate treatment at home in 29% of cases. During 1 year of follow-up the mortality in patients treated with rt-PA was 10.2%, as compared with 14.3% in patients the initial ECG, the mortality during the first year was 8% in the rt-PA group vs. 18% in the placebo group (P less than 0.05). Among patients without ST-elevation the mortality was 9% for the rt-PA group vs. 12% for the placebo group (NS). Requirement for rehospitalization, symptoms of angina pectoris and congestive heart failure, time of return to work and requirement for various medications did not differ significantly between the two groups, regardless of the initial ECG pattern.

- To evaluate morbidity and use of medical resources in patients with chest pain and normal or near-normal coronary angiograms: 2,639 consecutive patients who underwent coronary angiograms due to chest pain were registered. Two years thereafter all patients who showed normal or near-normal coronary angiograms were approached with a questionnaire regarding hospitalization during the last 4 years (2 years before and 2 years after angiography). All medical files were also examined. Of the patients who underwent angiography, 163 (6%) had no significant stenoses, and of these, 113 showed complete normal angiograms and 50 showed mild (i.e. <50%) stenoses. During the 2 years before diagnostic angiogram, 66% of the patients were hospitalized compared with only 35% during 2 years after angiography (p <0.001). The reduction in hospitalization was due to curtailed utilization of medical resources for cardiac reasons; mean days in hospital was 6.6 days before angiography versus 2.8 days after (p <0.001). There were no significant differences in hospitalization when comparing patients with mild stenoses and completely normal angiograms. There were, furthermore, no differences between patients with positive or negative exercise tests. Thus, the need for hospitalization is significantly reduced after a diagnostic angiogram reveals normal or near-normal coronary arteries.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to describe the possibility of influencing components of hospital delay time within the emergency department (ED) among patients with ST-elevation on the initial electrocardiogram (ECG). Nurses recorded seven patient time points: (1) ED admission; (2) ECG recording; (3) decision by nurse/ED physician; (4) cardiologist ED arrival; (5) decision of coronary care unit (CCU) admission; (6) ED departure; (7) CCU arrival. After special training in ECG, nurses in the ED were subsequently delegated to send patients directly to the CCU if showing ST-elevation on the admission ECG without contacting either the physician in ED or the cardiologist on call (intervention). Delay times between hospital admission and admission to the CCU were evaluated during the 9 months prior to and during the 6 months after the start of this intervention. Fifty patients (66% men) participated in the first study during 3 months (prior to intervention). Patients with suspected or confirmed acute myocardial infarction (AMI) in the ED had a median delay time from ED arrival to CCU arrival of 55.5 minutes (34.5 minutes for patients with confirmed AMI; ST elevation on admission). Time interval from decision to admit to CCU and ED departure was an average of 31% of the total delay. A mean of 21% of total delay occurred between ED decision to cardiologist arrival, and 19% during the time interval from cardiologist ED arrival until decision to CCU admission. Among patients receiving thrombolysis, the median delay time from hospital admission to CCU admission was reduced from 40 minutes during the 9 months prior to start of the intervention (nurses sending patients directly to the CCU) to 22 minutes during the 6 months thereafter (p = 0.02). The largest proportion of hospital delay components for acute coronary syndrome patients occurred between the cardiologist's decision to admit to the CCU and departure from the ED, and the interval following the decision by the nurse or physician to the cardiologist ED arrival. When nurses were delegated to transfer patients with ST-elevation on admission directly to the CCU without contacting a physician, the delay time from ED admission to CCU admission was reduced by nearly 50%.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study was to describe mortality during the 2-year-period after coronary artery bypass surgery (CABG) in relation to perioperative risk factors and urgency of operation. All the patients in western Sweden were included in whom CABG was performed between June 1988 and June 1991, without concomitant procedures or re-operations. The study was prospective in design. In all, 2000 patients were operated upon and 186 (9.3%) of the operations were acute. There was a significant relationship between the urgency of the operation and mortality. Early mortality was 2.4% in elective operations and 5.4-62.5% in urgent to emergency operations. The 30-day to 2-year mortality was 4.2%. The perioperative risk indicators independently associated with early mortality were neurologic complications, serum-aspartate aminotransferase (S-ASAT) more than 2.0 microkat/l, urgency of operation, the use of circulatory assist devices, re-operation and ventilator time more than 24 h. The risk indicators for mortality after 30 days were pneumothorax, longer intensive care unit (ICU) time, the use of inotropic drugs and neurologic complications. In conclusion, the multivariate analysis reveals the urgency of the operation as a predictor of early mortality after CABG, but no significant association with mortality was found after 30 days. When excluding death within 30 days, three additional independent predictors of mortality were identified.
