- At present there are about 1 million trained cardiopulmonary resuscitation (CPR) rescuers in Sweden. CPR out-of-hospital is initiated about 2000 times a year in Sweden. However, very little is known about the bystanders' experiences and reactions. The aim of this study was to describe bystander-initiated CPR, the circumstances, the bystander and his experiences. All CPR bystanders in Sweden who reported their resuscitation attempts between 1990 and 1994 were approached with a phone interview and a postal questionnaire, resulting in 742 questionnaires. Bystander-initiated CPR most frequently took place in public places such as the street. The rescuer most frequently had problems with mouth-to-mouth ventilation (20%) and vomiting (18%). More than half (53%) of the rescuers experienced CPR without problems. Ninety-two percent of the bystanders had no hesitation because of fear of contracting the acquired immunodeficiency syndrome (AIDS) virus. Ninety-three percent of the rescuers regarded their intervention as a mainly positive experience. Of 425 interviewed rescuers, 99.5% were prepared to start CPR again.

- The incidence of Sweden's out-of-hospital cardiac arrests averages 10000 annually. Each year bystanders initiate cardiopulmonary resuscitation (CPR) approximately 2000 times prior to arrival of emergency medical service (EMS). The aim of this study was to identify factors influencing the bystanders psychological reactions to performing CPR. We mailed a questionnaire to all bystanders who reported performing CPR to the CPR Centre of Sweden from autumn 1992 to 1995. The study included 544 bystander reports. Nine factors were found to be associated with bystanders experience in a univariate analysis. Among these were victim outcome (p < 0.0001), CPR duration (p = 0.0009) and their experience of the attitude of the EMS personnel (p = 0.004). In a multivariate logistic regression model, lack of debriefing following the intervention (p = 0.0001) and fatal victim outcome (p = 0.03) were independent predictors of a negative bystander psychological reaction. The importance of having someone to talk to following an intervention and the EMS personnel concern for the rescuer should be emphasised. The goal should be that critical incident debriefing is available to every bystander following his or her CPR attempt.

- OBJECTIVE: To examine the consequences for close family members of patients on a waiting list for possible coronary revascularization. BACKGROUND: An increasing number of patients with symptomatic ischemic heart disease require evaluation for possible revascularization. Many of these patients must wait a long time before receiving treatment. The negative consequences of this long wait for patients and their relatives have not been satisfactorily evaluated previously. DESIGN: Cross-sectional descriptive study. SETTING: All hospitals in Southwestern Sweden. STUDY POPULATION: One hundred relatives of patients referred for possible revascularization and a sex- and age-matched reference group. The convenience sample consisted of 85% (n = 76) women and 15% (n = 13) men. OUTCOME MEASURES: Frequency of cardiovascular and psychosomatic symptoms. EVALUATION: One hundred relatives and 100 members of the control group were sent a questionnaire to evaluate their clinical condition; working situation; use of tobacco, alcohol and sedatives; and cardiovascular and psychosomatic symptoms. RESULTS: Family members had a significantly higher frequency of anxiety, depression, and irritability compared with the control group. Furthermore, family members reported sleeping disorders, including difficulty waking, tiredness due to lack of sleep, and restless sleep, more frequently than did the control group. CONCLUSION: Close family members of patients waiting for coronary revascularization have particular difficulties, and these difficulties should receive more attention.

- AIM: To describe the occurrence of death, development of acute myocardial infarction and need for hospitalization among patients on the waiting list for coronary artery by pass grafting and percutaneous transluminal coronary angioplasty. PATIENTS AND METHODS: All the patients on the waiting list for possible coronary revascularization in September 1990 in western Sweden. RESULTS: Of 718 patients waiting for either coronary artery bypass grafting or percutaneous transluminal coronary angioplasty, 15 (2.1%) died between the actual week in September 1990 and prior to revascularization and 12 (1.7%) developed a non-fatal acute myocardial infarction during the same period. All 15 patients who died before undergoing revascularization died a cardiac death. Death and/or the development of an acute myocardial infarction was significantly more frequent among the elderly, among patients with a low ejection fraction and among patients with a history of diabetes mellitus. In all, 29% required hospitalization prior to the procedure. The most common reason was symptoms of angina pectoris requiring hospitalization in 23% of the patients. CONCLUSION: Among patients on the waiting list before either coronary artery bypass grafting or percutaneous transluminal coronary angioplasty, 15 (2.1%) died prior to the procedure and 1.7% developed a non-fatal acute myocardial infarction. The risk of either death or developing an acute myocardial infarction was highest among patients in the older age groups, among patients with a history of diabetes mellitus and among patients with a lower ejection fraction.

- AIM: To describe various symptoms other than pain among consecutive patients on the waiting list for possible coronary revascularisation in relation to estimated severity of chest pain. DESIGN: All patients were sent a postal questionnaire for symptom evaluation. SUBJECTS: All patients in western Sweden on the waiting list in September 1990 who had been referred for coronary angiography or coronary revascularisation (n = 904). RESULTS: 88% of the patients reported chest pain symptoms that limited their daily activities to a greater or lesser degree. Various psychological symptoms including anxiety and depression were strongly associated with the severity of pain (P < 0.001), as were sleep disturbances (P < 0.001), and dyspnoea and various psychosomatic symptoms (P < 0.001). Nevertheless only 44% of the patients reported chest pain as the major disruptive symptom, whereas the remaining 56% reported uncertainty about the future, fear, or unspecified symptoms as being the most disturbing. CONCLUSIONS: In a consecutive series of patients on the waiting list for possible coronary revascularisation, half the participants reported that uncertainty and fear were more disturbing than chest pain.

- Objective. —To evaluate the appropriateness of performing coronary angiography and revascularization in a Swedish population. Design. —Prospective population study of questionnaires and medical records. Setting. —All the hospitals in southwestern Sweden that perform coronary angiography and revascularization. Patients. —Random sample of 831 patients (with chronic stable angina) on the waiting list for coronary angiography or revascularization in southwestern Sweden in September 1990. Main Outcome Measure. —Percentage of patients referred for coronary angiography or revascularization for appropriate, uncertain, or inappropriate indications. Results. —Of the patients referred for angiography, 89% were classified as appropriate, 9% as uncertain, and 2% as inappropriate. The percentages are similar for patients referred for coronary artery bypass graft surgery and for angioplasty (91% and 86%, respectively, classified as appropriate). The majority of patients had chest pain rated as Canadian Cardiovascular Society classes II through IV (93%), despite maximum anti-ischemic therapy in 90% of these patients. Conclusions. —Few patients were referred for coronary angiography or revascularization for inappropriate or uncertain indications. The percentage of these patients who are from southwestern Sweden is similar to the percentage recently reported from New York State.

- Keywords: cardiac symptoms; chest pain; coronary revascularization; delay; ischaemic heart disease; nervous reactions; waiting list Abstract. Objectives. To describe the characteristics and the severity of symptoms amongst patients on the waiting list for possible coronary revascularization. Design. All the patients were sent a postal questionnaire for symptom evaluation. Setting. All hospitals in western Sweden. Subjects. All patients in western Sweden on the waiting list in September 1990, who had been referred for coronary angiography or revascularization (n = 904) and a sex- and age-matched reference group (n = 809). Results. More than half of the patients had daily attacks of chest pain, whereas 16% reported less than one attack per week or no pain at all. However, other symptoms such as dyspnoea, tachycardia and nervous reactions were also common and 25% of all patients used sedatives. A long waiting time for a given procedure was not associated with more pain but with more nervous symptoms such as restlessness and insomnia (P < 0.0001) and greater use of sedatives and cigarettes (P < 0.05). Conclusions. We conclude that a long waiting time for possible coronary revascularization is associated with more nervous symptoms but not with more pain.

- 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.
