- The characteristics and the prognosis in 921 consecutive patients with acute myocardial infarction (AMI) admitted to one single hospital are described and related to whether they were treated in the coronary care unit or not. Patients treated in the coronary care unit (n = 779) had a 1-year mortality rate of 26% as compared with 41% for patients treated in general wards (n = 115; p < 0.001) and 74% for patients treated in the intensive care unit (n = 27; p < 0.001). Patients treated outside the coronary care unit had a different risk factor pattern including a higher age and a higher prevalence of a previous cardiovascular disease. Independent clinical risk indicators for death among patients in the coronary care unit were in order of significance, high age (p < 0.001), arrhythmia on admission (p < 0.01), acute congestive heart failure on admission (p < 0.01) and a history of diabetes mellitus (p < 0.05). In patients treated in general wards, the only risk indicator for death was a history of congestive heart failure.

- The prognosis during 1 year of follow-up in 715 patients admitted to one single hospital due to suspected acute myocardial infarction (AMI) with a history of unstable angina pectoris immediately preceding hospitalization is described. AMI developed in 192 patients (27%) during the first three days and in 255 patients (38%) during the first year. The mortality during hospitalization was 7% (50 patients) and during 1 year 19% (130 patients). Of the nonsurvivors, 54% died of AMI, 28% of congestive heart failure, and 20% of cardiogenic shock. Based on simple clinical parameters on admission to the emergency room, risk indicators for death during the following year could be identified as follows, in the order of significance: high age (p < 0.001), ST-segment depression on admission (p < 0.001), and a history of diabetes mellitus (p < 0.05). At admission to the emergency room, risk indicators for development of AMI during the following year were as follows: initial degree of suspicion of AMI (p < 0.001), electrocardiographic signs of acute ischemia on admission (p < 0.001), ST-segment elevation on admission (p < 0.01), age (p < 0.05), and lack of a previous history of chronic stable angina pectoris (p < 0.05). We conclude that, among patients admitted to hospital due to suspected AMI with a history of unstable angina pectoris immediately preceding hospitalization, 38% developed a confirmed infarction and 19% died during the following year.

Prognosis in suspected acute myocardial infarction in relation to delay time between onset of symptoms and arrival in hospital
- 1991

Tidskriftsartikel (refereegranskat)abstract
- During a 21-month period, the prognosis in all patients admitted to a hospital ward from the emergency room with suspected acute myocardial infarction (AMI) was prospectively recorded and related to the time between onset of symptoms and arrival in hospital. They were classified as early arrivers (less than or equal to 2 h), intermediate arrivers (2-8 h) and late arrivers (greater than 8 h). Among patients developing a confirmed AMI (n = 909) the 1-year mortality rate was 26.0% in early arrivers, 28.1% in intermediate arrivers and 32.6% in late arrivers. The corresponding figures for patients in whom AMI was ruled out (n = 2,035) were 15.2, 15.1 and 17.6%, respectively. In AMI patients, various morbidity aspects during hospitalization and 1 year of follow-up appeared mainly independent of delay time, whereas among those in whom AMI was ruled out congestive heart failure during hospitalization was most common in early arrivers. We conclude that patients with suspected AMI who do not arrive early in hospital have a high 1-year mortality rate regardless of whether they develop AMI or not. Whether their prognosis can be improved by shortening of delay time remains to be clarified.

Swedish obese subjects (SOS). Recruitment for an intervention study and a selected description of the obese state
- 1992

Tidskriftsartikel (refereegranskat)abstract
- Department of Medicine, Sahlgren's Hospital, University of Göteborg, Sweden. SOS (Swedish obese subjects) is an on-going intervention trial designed to determine whether the mortality and morbidity rates among obese individuals who lose weight by surgical means (gastric banding, vertical banded gastroplasty and gastric by-pass) differ from the rates associated with conventional treatment. For this purpose, the study is recruiting a sample of obese men and women who constitute a registry of potential subjects from which the participants are drawn. Eligibility criteria for participation in the registry were: age at application 37-57 years and BMI greater than or equal to 34 kg/m2 for men and greater than or equal to 38 kg/m2 for women. Before receiving a health examination, all patients complete extensive questionnaires on current and past health status, utilization of medical care and medications, socio-economic status, psychological profiles, dietary habits, physical activity, weight history, and familial disposition to obesity. Each surgical case is matched to its optimal control in the registry, to ensure that the two groups do not differ systematically with respect to any of 18 matching variables that may affect prognosis. The first 1006 subjects included in the registry have been studied with respect to morbidity and compared with on-going population studies of men and women in Göteborg, Sweden. The relative risks of prevalent disease and symptoms associated with obesity in 50-year-old males and females respectively were 4.3 and 4.7 (dyspnoea), 14.7 and 11.8 (angina), 6.3 (myocardial infarction, males only), 2.1 and 4.5 (hypertension), 5.2 and 6.6 (diabetes), 4.6 and 26.1 (claudication) and 1.7 and 1.8 (gall bladder disease). Correspondingly, obese males and females display elevations of systolic and diastolic blood pressure, fasting glucose, insulin, triglyceride, and uric acid levels. However, total cholesterol was not increased in obese males and was in fact significantly lower in obese compared with reference women. HDL-cholesterol was lower in obese than reference men (data were not available in reference women). The rate of taking sick pensions was over twice as high in SOS obese patients than in population controls. Finally, comparison of measurements with self-reported prevalence estimates revealed a considerable amount of previously undiagnosed hypertension and diabetes in the obese subjects. These data suggest that the excess health risks associated with obesity may not be fully appreciated. PMID: 1322873 [PubMed - indexed for MEDLINE]
