- This study aims to examine the situation for patients on the waiting list for possible coronary revascularization in terms of waiting time, treatment and various aspects of well-being in relation to gender. Patients on the waiting list for coronary angiography, percutaneous transluminal coronary angioplasty or coronary artery bypass grafting in September 1990 were approached with a questionnaire dealing with various aspects as described above. Of the 831 patients who participated in the evaluation, 174 (21%) were women. Although age was similar for men and women, men had a higher prevalence of previous myocardial infarction and a lower prevalence of previous hypertension. In terms of medication, women were more frequently treated with diuretics and sedatives than men. Women reported a higher frequency than men with regard to the following symptoms: chest pain at rest and at night, dyspnoea when walking, tachycardia, tiredness, headache, dizziness and sweating. Women also suffered more frequently from difficulty going to sleep, difficulty waking up, repeated awakening and insomnia. Men, on the other hand, suffered more frequently from restlessness, inability to act and irritability. Among patients on the waiting list for possible coronary revascularization, women differed from men by being more frequently treated with diuretics, reporting a higher frequency of various cardiovascular symptoms including chest pain and dyspnoea and, furthermore, reporting more sleeping disorders. Gender differences were found but they were not consistent.

- In acute ST-elevation infarction two different reperfusion strategies--thrombolytic medication and acute coronary angiography--have proved to improve the prognosis. The clinical course for patients with ST-elevation infarction is described in relation to whether they received thrombolytic medication or underwent acute coronary angiography with the aim of mechanical revascularization. The one-year mortality was high (20 percent) regardless of treatment strategy. In terms of morbidity there were no clear differences between the two treatment groups.

- Treatment of acute myocardial infarction (AMI) is changing, and differences in medical practice are observed within and between countries on the basis of local practice patterns and available technology. These differing approaches provide an opportunity to evaluate medical practice and outcomes at the population level. The primary aim of this study was to compare medical care in patients hospitalized with AMI in 2 large cities in Sweden and the United States. A secondary aim was to compare medical outcomes.

- BACKGROUND: Most patients with acute coronary syndrome quit smoking when hospitalized, although several have been found to relapse and resume smoking within 3 months. AIM: This paper reports a study to identify factors that can predict who will resume smoking after hospitalization for an acute coronary syndrome. METHODS: Patients (n = 1320) below the age of 75 years, admitted to a Swedish university hospital coronary care unit with acute coronary syndromes, between September 1995 and September 1999, were consecutively included. Data were collected from hospital medical records and included information on previous clinical history, former illnesses and smoking. During their hospitalization, an experienced nurse interviewed the patients by using a structured questionnaire to obtain additional information. Patients were followed up 3 months after the discharge. Those who continued to smoke (non-quitters) were compared with those who had stopped (quitters) with regard to age, sex, medical history, clinical course, and intention to quit. To identify factors independently related to continued smoking, a logistical regression in a formal forward stepwise mode was used. RESULTS: Of the patients admitted, 33% were current smokers. Three months after discharge, 51% of these patients were still smoking. There were no significant differences in age, gender or marital status between non-quitters and quitters. In a multivariate analysis, independent predictors of continued smoking were: non-participation in the heart rehabilitation programme (P = 0.0008); use of sedatives/antidepressants at time of admission (P = 0.001); history of cerebral vascular disease (P = 0.002), history of previous cardiac event (P = 0.01); history of smoking-related pulmonary disease (P = 0.03) and cigarette consumption at index (P = 0.03). CONCLUSIONS: Smoking patients who do not participate in a heart rehabilitation programme may need extra help with smoking cessation. The findings may provide means of identifying patients in need of special intervention.

- The aim of this study was to evaluate short- and long-term outcome prior to and after the introduction of a more intensified treatment in the ambulance of patients with acute severe heart failure. Consecutive patients with acute severe heart failure transported by the mobile coronary care unit (MCCU) in the community of Göteborg prior to and after the introduction of an intensified treatment (nitroglycerine, continuous positive airway pressure (CPAP) and furosemide). One hundred and fifty-eight patients were evaluated during each period. The median age was 77 and 76.5 years, respectively, and 52% and 42% were women. The proportion of patients given nitroglycerine in the ambulance was 4% and 68% in the two periods; the proportion of patients treated with furosemide was 13% and 84%, respectively. CPAP was used in less than 1% during period 1 and in 91% during period 2. On admission of the ambulance 60% had fulminant pulmonary oedema during period 1 versus 78% during period 2 (p<0.0001). On admission to hospital the opposite was found, 93% during period 1 versus 76% during period 2 (p<0.0001). The median serum creatinine kinase (CK-MB) maximum activity was 13 microkat/l during period 1 and 8 microkat/l during period 2 (p = 0.007). However, the mortality during the first year remained high during both periods (39.2% and 35.8%, p = 0.64). It is concluded that a more intensive treatment in the ambulance of patients with acute severe heart failure seems to have resulted in an improvement in symptoms during transport and less myocardial damage. However, no significant improvement in long-term mortality was observed.

- Signal-averaged electrocardiograms (SAECG) were analyzed for late potentials and spectral turbulence in 208 patients with ischemic heart disease with a history of sustained monomorphic ventricular tachycardia (MVT) (n = 62), resuscitation from ventricular fibrillation (VF) (n = 64) or no ventricular tachyarrhythmia (n = 82). Receiver operating characteristic curves were utilized to optimize cut-off values for prediction of MVT and VF. Patients with MVT had a lower ejection fraction (mean = 0.37) than patients with VF (0.44; p = 0.01) and controls (0.48; p < 0.0001). The mean FQRSD in MVT patients (126 ms) was longer than in VF and controls (113 ms; p = 0.005 and 102 ms; p < 0.0001, respectively). The RMS40 was lower in MVT (19 microV) than in VF and controls (29 microV; p = 0.0003 and 28 microV; p < 0.0001, respectively); 81% of the MVT patients were spectral turbulence-positive vs 47% of VF patients and 31% of control patients (p < 0.0001 for both differences). With optimized reference values, FQRSD, TQRSD and ISCSD contributed significantly to the identification of MVT patients and FQRSD to VF patients. The sensitivity of combined time-domain and spectral turbulence analysis was 90% for MVT and 58% for VF, with 63% specificity. MVT patients had a lower ejection fraction and were more often late potential and spectral turbulence positive than VF and control patients. These findings indicate that a large electroanatomic substrate is required in MVT. A long FQRSD was a risk marker for both MVT and VF. Spectral turbulence analysis added independent information, and the combination of time-domain and spectral turbulence analysis was superior to either method alone in identifying the MVT patients. Neither method of analysis, singly nor in combination, performed satisfactorily in identification of VF risk.

- Previous methods for frequency domain analysis of the signal-averaged ECG (SAECG) have had low reproducibility. The reproducibility of time domain late potential analysis and spectral turbulence analysis was evaluated with 2 immediately consecutive SAECG recordings in 121 randomly selected subjects without heart disease (short-term) and also in 47 subjects after 1 month (long-term). A test was late potential positive if 2 or more of 3 variables were outside the reference limits and spectral turbulence positive if the score was 3 or 4. The short-term reproducibility was high for the filtered QRS duration (FQRSD), root mean square amplitude of the last 40 ms (RMS40) and high frequency low amplitude signals less than 40 microV (HFLAS40) of the time domain and total QRS duration (TQRSD), power spectral density of the last 40 ms and the late potential duration of time domain analogous analyses. The Spearman rank order correlation coefficients were 0.89, 0.88, and 0.84 and 0.97, 0.91 and 0.97, respectively. The reproducibility of the spectral score variables varied, and the correlation for the low slice correlation ratio was 0.71, spectral entropy 0.61, interslice correlation mean 0.58, and interslice correlation SD 0.28. A diagnostic inconsistency between 2 tests occurred in 0 (0%) subjects in late potential analysis if FQRSD was required for positivity, and in 7 (6%) otherwise, and in 9 (7%) of spectral turbulence analysis. If the spectral variable mean peaks per slice, with a correlation of 0.89, replaced interslice correlation SD in the spectral score, diagnostic inconsistency occurred in 0 (0%) subjects. The reproducibility seemed higher in women and in younger people but significantly only for interslice correlation subjects mean and HFLAS40. The long-term reproducibility did not differ significantly from short-term for any variable. In conclusion, the reproducibility was high in all time domain and time domain analogous variables. It varied among the spectral turbulence score variables and was very low for interslice correlation SD. The reproducibility of the spectral score improved substantially if this variable was replaced by mean peaks per slice.
