Tidskriftsartikel (refereegranskat)abstract
- The Minnesota Heart Health Program was a community trial of cardiovascular disease prevention methods that was conducted from 1980 to 1990 in three Upper Midwestern communities with three matched comparison communities. A 5- to 6-year intervention program used community-wide and individual health education in an attempt to decrease population risk. A major hypothesis was that the incidence of validated fatal and nonfatal coronary heart disease and stroke in 30- to 74-year-old men and women would decline differentially in the education communities after the health promotion program was introduced. This hypothesis was investigated using mixed-model regression. The intervention effect was modeled as a series of annual departures from a linear secular trend after a 2-year lag from the start of the intervention program. In the education communities, 2,394 cases of coronary heart disease and 818 cases of stroke occurred, with 2,526 and 739 cases, respectively, being seen in the comparison communities. The overall decline in coronary heart disease incidence was 1.8 percent per year in men (p = 0.03) and 3.6 percent per year in women (p = 0.007). For stroke, there were no significant secular trends. The authors recently published findings showing minimal effects of sustained intervention on risk factor levels. In the current report, there was no evidence of a significant intervention effect on morbidity or mortality, either for coronary heart disease or for stroke.

- 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 transport to the hospital. The target population was the general public. After 6 and 12 months 400 and 610 randomly chosen persons, respectively, were contacted by telephone to evaluate the reaction of the general public to the campaign. Of these, 60% and 71%, respectively, had heard of the campaign, and all parts of the message were spontaneously remembered by 15% and 19%, respectively. The reaction to the campaign was generally positive. Among all patients admitted to the coronary care unit of one of the two city hospitals, 65% were aware of the campaign and 31% of them were of the opinion that they came to the hospital faster because of the campaign. In conclusion, a media campaign aimed at reducing patient delay time in acute myocardial infarction was shown to reach a majority of people in the community and patients with ischemic heart disease. The reaction was positive and about one fifth of interviewed people spontaneously remembered the total message.

- It is difficult to assemble data from an previous termout-of-hospital cardiac arrestnext term since there is often lack of objective information. The true incidence of previous termsudden cardiacnext term death previous termout-of-hospitalnext term is not known since far from all of these patients are attended by emergency medical services. The incidence of previous termout-of-hospital cardiac arrestnext term increases with age and is more common among men. Among patients who die, the probability of having a fatal event outside previous termhospitalnext term decreases with age; i. e. younger patients tend to more often die unexpectedly and outside previous termhospital.next term Among the different initial arrhythmias, ventricular fibrillation is the most common among patients with previous termcardiacnext term aetiology. The true distribution of initial arrhythmias is not known since several minutes most often elapse between collapse and rhythm assessment. Most patients with previous termout-of-hospital cardiac arrestnext term have a previous termcardiacnext term aetiology. previous termOut-of-hospital cardiac arrestsnext term most frequently occur in the patient's home, but the prognosis is shown to be better when they occur in a public place. Witnessed previous termarrest,next term ventricular fibrillation as initial arrhythmia and cardiopulmonary resuscitation are important predictors for immediate survival. In the long-term perspective, previous termcardiac arrestnext term in connection with acute myocardial infarction, high left ventricular ejection fraction, moderate age, absence of other heart failure signs and no history of myocardial infarction promotes better prognosis. Still there is much to learn about time trends, the influence of patient characteristics, comorbidity and previous termhospitalnext term treatment among patients with prehospital previous termcardiac arrest.

Tidskriftsartikel (refereegranskat)abstract
- The early phase in suspected acute myocardial infarction (AMI) is particularly critical. More than 50% of deaths from coronary artery disease occur outside the hospital mainly due to ventricular fibrillation.1 Recent experiences strongly indicate that early intervention with thrombolysis2–4 and β blockers5,6 can limit myocardial damage and thereby improve prognosis. Delay times in suspected AMI have remained stable over the years. Therefore, a media campaign was started in the urban area of Göteborg, Sweden, with the intention to shorten delay times and to increase ambulance use in patients with suspected AMI.

- OBJECTIVES: To describe the characteristics and outcome of patients with acute myocardial infarction (AMI) in a community, with particular emphasis on those who never reached a Coronary Care Unit (CCU) and those in whom the primary diagnosis was something other than a heart attack. METHODS: Patients hospitalised in the city of Goteborg, Sweden, and discharged (dead or alive) with a diagnosis of AMI. RESULTS: Among 1423 patient admissions the mean overall age was 75 years (81 years and 79 years in the two subsets). Among all patients, 33% had a history of heart failure and 20% had a history of cerebrovascular disease. The figures were even higher in the two subsets which were evaluated. In overall terms, an invasive strategy (coronary angiography) was used in 32% (in 5% and 9% in the two subsets respectively). The overall one-year and three-year mortality rate was 30% and 44% respectively. The three-year mortality rate among patients not admitted to a CCU was 65% and, among patients with no suspicion of a heart attack on admission, it was 68%. CONCLUSION: Even in the 21st century, patients with AMI who reach hospital alive run a high risk of death and nearly half are dead within the first three years. In overall terms, patients are characterised by high age and high co-morbidity. Among patients who do not reach a CCU and among patients with no suspicion of AMI on admission, approximately two thirds are dead within the subsequent three years.

- 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 were compared with the previous 21 months. Among patients admitted to a coronary care unit (CCU) due to suspected AMI, the median delay time was reduced from 3 h to 2 h 40 min and the mean delay time was reduced from 11 h 33 min to 7 h 42 min (P <0.001). Among patients with confirmed AMI the median delay time was reduced from 3 h to 2 h 20 min and the mean delay time from 10 h to 6 h 27 min (P <0.001). We conclude that a 1-year media campaign can reduce delay times in suspected AMI, and that this effect appears to continue at 1 year, but ambulance use seems to be more djfficult to influence.

- We compared medical care and mortality through 1-year of hospitalized acute myocardial infarction (AMI) patients in 2 large metropolitan areas in the United States and Sweden. All hospitalized AMI discharges (International Classification of Diseases, 9th revision [ICD9] codes 410) occurring among 30 to 74-year-old residents of the Minneapolis-St. Paul metropolitan area in 1990 and Göteborg, Sweden, in 1990 to 1991 were identified and their medical records examined. There were dramatic differences in medical care during the index hospitalization of AMI patients between Minneapolis-St. Paul and Göteborg. Use of thrombolytic therapy, coronary angioplasty, bypass surgery, calcium antagonists and lidocaine was more common in Minneapolis-St. Paul; beta blockers were more frequently used in Göteborg, and aspirin use was similar. Despite these large differences, neither 28-day nor 1-year mortality of hospitalized AMI patients differed significantly. The marked differences found in the early treatment of AMI between Minneapolis-St. Paul and Göteborg, combined with the negligible differences observed in short- and long-term mortality, raise questions about the most effective and efficient allocation of medical resources.

Tidskriftsartikel (refereegranskat)abstract
- In 319 patients who participated in a double-blind trial to evaluate the effect of early rt-PA administration compared to placebo in suspected acute myocardial infarction, infarct size was assessed from analyses of serum activity of lactate dehydrogenase isoenzyme 1 (LD 1). Treatment was always started less than 3 h after the onset of symptoms, with one-third of the patients' treatment being initiated outside the hospital. The maximum activity of LD 1 was reduced by 32%, from 13.3 mu kat l-1 in placebo to 9.0 mu kat l-1 in rt-PA treated patients (P = 0.001). A reduction in LD-1 activity after rt-PA treatment was restricted to patients with ST-elevation in the initial electrocardiogram, and was more pronounced in patients with previous ischaemic heart disease, above median age, and in those with a shorter delay in initiation of treatment. We conclude that very early intravenous treatment with rt-PA limits indirect signs of infarct size. The effect appears to be restricted to patients with ST-segment elevation in their initial electrocardiogram.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: The aim of this study was to investigate the influence of diabetes on treatment and outcome in acute myocardial infarction (AMI), during two time periods, in two countries, and to assess whether this influence has changed over the past decades. METHODS: Patients, aged 30 to 74, with a diagnosis of AMI in two urban areas--Goteborg, Sweden and Minneapolis-St. Paul, Minnesota, USA--hospitalized during 1990-1991 and 1995-1996 were included. The primary endpoint was 7-year all-cause mortality. RESULTS: The study included 3824 patients, 734 (19%) had diabetes. Age-adjusted in-hospital mortality of diabetic patients was nearly twofold higher compared with non-diabetic patients (9.8% vs. 5.0%, p<0.05). Between 1990-1991 and 1995-1996 in-hospital mortality declined for both diabetic (11.9% vs. 7.6%, p=0.07) and non-diabetic (6.3% vs. 3.6%, p=0.002) patients. A history of diabetes was associated with nearly twofold higher long-term mortality rate (48.5% vs. 26%, p<0.05). Seven-year mortality was reduced between 1990-1991 and 1995-1996 in both diabetic (51.6% vs. 45.2%, p=0.13) and non-diabetic patients (29.3% vs. 22.1%, p<0.0001) (The results did not reach statistical significance for diabetic patients, due to smaller sample size.) During their hospital stay, diabetic patients received significantly less aspirin, beta-blockers and thrombolysis. After adjustment, a history of diabetes remained significantly associated with 7-year mortality following AMI, doubling the hazard of death (hazard ratio (HR)=2.11; 95% confidence interval (CI): 1.80-2.46). CONCLUSION: A history of diabetes is associated with nearly twofold higher long-term mortality rate and is independently associated with 7-year mortality following AMI. Short- and long-term mortality decreased from 1990 to 1995 in both non-diabetic and diabetic patients. Underutilization of evidence-based treatments contributes to the remaining increased mortality in diabetic patients with acute coronary disease.

- Swedish guidelines on treatment of hyperlipidemia recommend higher cut-off levels for initiating treatment than do American guidelines, but are virtually identical for instituting and performing therapy. The aim of this study was to compare family physicians' reported practices in Sweden and Minnesota. We selected random samples of family physicians in southern Sweden and Minnesota for telephone interviews. Participation rates were 236/264 (89%) and 183/209 (88%), respectively. Swedish and Minnesota physicians adhered to their guidelines on cut-off levels in a case describing a 48-year-old man but, contrary to guidelines, reported higher cut-off levels for a 65-year-old man and a 65-year-old woman. In all cases described, Swedish physicians reported significantly higher cut-off levels. Swedish physicians were less prone to institute medication in older patients and less familiar with drugs. Minnesota physicians were more inclined to advise nicotinic acid derivatives (P < .0001 for all patient categories). Swedish physicians more frequently preferred resins (P = .00029) or fibrates (P = .0028) for the 48-year-old man and resins for the 65-year-old man (P = .0026). Despite common medical knowledge, the two medical communities are directed by different guidelines. Although adherence to cut-off levels was equally high in both groups, the use of lipid-lowering drugs has not become a familiar part of the therapeutic armamentarium for Swedish family physicians.

- OBJECTIVES. To compare family physicians' reported practice habits on hypertension in Sweden and Minnesota, and to assess to what extent different national guidelines account for differences. DESIGN. Random samples of family physicians were selected for telephone interviews on their practice of hypertension. SETTING. Primary care in southern Sweden and in Minnesota. SUBJECTS. Family medicine specialists. Participation rates were 236/264 (89%) in Sweden and 183/209 (88%) in Minnesota. MAIN OUTCOME MEASURES. Cut-off levels, and non-pharmacological and pharmacological treatment of hypertension, related to three case scenarios: a 48-year-old man, a 65-year-old man and a 65-year-old woman. RESULTS. Swedish physicians reported significantly higher levels of diastolic blood pressure than Minnesota physicians for the institution of treatment of hypertension for all case scenarios. In both countries, physicians adhered to the cut-off levels of their national guidelines in the case of the 48-year-old man. Minnesota physicians did not use age as a modifying factor for treatment cut-off levels, as did Swedish physicians. Swedish physicians emphasized alcohol, fat and stress reduction, and Minnesota physicians weight and salt reduction as non-pharmacological treatment. While Swedish physicians generally preferred beta-blockers, Minnesota physicians chose ACE inhibitors or calcium channel blockers as the first choice drug. CONCLUSION. Swedish and US guidelines on hypertension were identical except for higher cut-off level for drug treatment in Sweden. Minnesota physicians reported cut-off levels close to national guidelines. For 65-year-old patients, Swedish physicians reported applying a higher cut-off level than indicated by guidelines. Swedish physicians also reported preferring less expensive drugs. As a consequence of the differing national guidelines and the identified physicians' practice habits in the two medical communities, it is likely that the segments of the populations treated and the drug costs differ substantially.
