  • Early identification of acute myocardial infarction and prognosis in relation to mode of transport
  • 1992
  • Ingår i: American Journal of Emergency Medicine. - : W.B. Saunders Co.. - 0735-6757 .- 1532-8171. ; 10:5, s. 406-412

    • Of 2,840 consecutive patients who were admitted to the emergency department of a Swedish university hospital due to suspected acute myocardial infarction (AMI), only 25% were reached by the mobile coronary care unit (MCCU), and only 4% simultaneously fulfilled traditional criteria for prehospital thrombolysis (ie, had ST-segment elevation on admission electrocardiogram and a delay time of less than 6 hours). In the subset of patients who fulfilled criteria for a confirmed AMI, 31% were reached by an MCCU and 11% fulfilled criteria for prehospital thrombolysis. Among patients with confirmed AMI, the hospital mortality rate was highest in patients transported by standard ambulance (19%) versus 15% in those transported by an MCCU and 8% in those transported by other means. The authors conclude that AMI patients transported by ambulance are high-risk patients for early death. Prehospital thrombolysis might reduce their rate of mortality. However, according to the authors' experience only a minor fraction of patients are available for prehospital thrombolysis.

  • Occurrence of angina pectoris prior to acute myocardial infarction and its relation to prognosis
  • 1993
  • Ingår i: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 14:4, s. 484-491

    • In 917 patients with acute myocardial infarction (AMI) we evaluated the impact of previous angina pectoris on the prognosis. Thirty-four percent of the patients had chronic angina prior to AMI, and 22% had angina pectoris of short duration. Patients with chronic angina pectoris differed from the remaining patients having a more frequent previous history of AMI, diabetes mellitus, hypertension, and congestive heart failure. They less frequently developed a Q-wave AMI, and had smaller infarcts according to maximum serum-enzyme activity as compared with the remaining patients. They had a higher one-year mortality rate (36%) as compared with those having angina pectoris of short duration (22%), and those with no angina pectoris (26%). Their reinfarction rate was also higher (26%) as compared with that in the other two groups (15% and 9% respectively). In a multivariate analysis considering age, sex, clinical history, initial symptoms, initial electrocardiogram and estimated infarct size, previous chronic angina pectoris was not an independent risk factor for death, but was independently associated with the risk of reinfarction (P<0.001) Among patients with a history of angina pectoris the outcome was related to medication prior to onset of AMI and at discharge from hospital. Patients in whom beta-blockers were prescribed at discharge had a one-year mortality of 13% as compared with 30% in the remaining patients

  • Prognosis for patients with initially suspected acute myocardial infarction in relation to presence of chest pain
  • 1992
  • Ingår i: Clinical Cardiology. - : John Wiley & Sons, Inc.. - 0160-9289 .- 1932-8737. ; 15:8, s. 570-576
  • Tidskriftsartikel (refereegranskat)abstract
    • In all 4,232 patients admitted to a single hospital during a 21-month period due to initially suspected acute myocardial infarction (AMI), the prognosis and risk factor pattern were related to whether patients had chest pain or not. Symptoms other than chest pain that raised a suspicion of AMI were mainly acute heart failure, arrhythmia, and loss of consciousness. In 377 patients (9%) symptoms other than chest pain raised an initial suspicion of AMI. These patients developed a confirmed infarction during the first three days in hospital with a similar frequency (22%) as compared with patients having chest pain (22%). However, patients with “other symptoms” had a one-year mortality of 28% versus 15% for chest pain patients (p < 0.001). Patients with “other symptoms” more often died in association with ventricular fibrillation and less often in association with cardiogenic shock as compared with chest pain patients. Among the 921 patients who developed early AMI, 64 (7%) had symptoms other than chest pain. They had a one-year mortality of 48% versus 27% for chest pain patients (p<0.001). We conclude that in a nonselected group of patients hospitalized due to suspected AMI, those with symptoms other than chest pain have a one-year mortality, which is nearly twice that of patients with chest pain.

  • Prognosis in hypertensives with acute myocardial infarction
  • 1992
  • Ingår i: Journal of Hypertension. - : Lippincott Williams & Wilkins, Ltd.. - 0263-6352 .- 1473-5598. ; 10:10, s. 1265-1271

    • OBJECTIVES: A previous history of hypertension is overrepresented among patients with ischaemic heart disease. The present study aims at describing the influence of a previous history of hypertension upon the prognosis among patients hospitalized due to acute myocardial infarction. DESIGN: Patients were followed for 1 year. Mortality and morbidity are described during hospitalization and after discharge from hospital. SETTING: Sahlgrenska Hospital, serving half of the area of Gothenburg in Sweden. PATIENTS: All patients admitted to Sahlgrenska Hospital during 21 months due to acute myocardial infarction regardless of age and whether they were admitted to the coronary care unit. RESULTS: Among all patients with confirmed acute myocardial infarction (n = 917) a previous history of hypertension was reported in 324 patients. Hypertensives more frequently had a previous history of acute myocardial infarction, angina pectoris, congestive heart failure and diabetes mellitus. Their mortality during hospitalization was similar to that in normotensives. However, the total mortality during 1 year of follow-up was 35% in hypertensives and 25% for normotensives (P < 0.01), and a previous history of hypertension was an independent risk indicator for death after discharge from hospital. Place and mode of death appeared similar in normotensives and hypertensives. Reinfarction was twice as common in hypertensives as in normotensives, and a previous history of hypertension was an independent risk indicator for reinfarction. CONCLUSIONS: Among patients with acute myocardial infarction a previous history of hypertension indicates a poor prognosis, one-third of patients dying and one-quarter developing reinfarction during the first year after onset of acute myocardial infarction.

  • Regional cerebral blood flow in schizophrenia: repeated studies during a psychotic episode
  • 1990
  • Ingår i: Psychiatry Research. - 1872-7123 .- 0165-1781. ; 35:1, s. 27-38
  • Tidskriftsartikel (refereegranskat)abstract
    • Regional cerebral blood flow (rCBF) measurements and clinical ratings were performed on 17 schizophrenic patients and a subgroup of 10 medication-free patients before and after treatment. While clinically exacerbated patients had normal blood flow, patients in remission showed a redistribution of flow with lower values in frontal areas. Anteroposterior ratios correlated with the degree of behavioral disturbances, suggesting that the level of frontal lobe activity in schizophrenia may be a function of the patient's clinical state at the time of study.

  • Subjective symptoms and wellbeing one year after acute myocardial infarction in relation to age
  • 1993
  • Ingår i: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 14:10, s. 1315-1319

    • The frequency of subjective cardiac and psychological complaints among men and women a year after a confirmed diagnosis of myocardial infarction (MI) were compared. Among 660 survivors, 595 patients completed mailed questionnaires at home one year after the MI. There were 421 men, mean age 67.1±10.7 years, and 174 women, mean age 72.1±10.6 years. Controlling for the significantly higher mean age among the women, the latter more often had a previous history of angina pectoris, 54.6% (P≤0.05) versus 42.9%, and heart failure, 24.7% versus 13.5% (P≤0.01). Despite these facts, the women were significantly less often referred to CCU, 82.2% versus 91.7% (P≤0.05). One year after the MI, controlling for differences in age and co-morbidity, women reported significantly higher frequencies of psychological and psychosomatic complaints, including sleep disturbances. These differences may have clinical implications for diagnosis and treatment of women with coronary heart disease.
