- 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.

- Pulsed tissue Doppler can measure myocardial velocities with high temporal resolution. Our aim was to determine the onset timing of the regional left ventricular longitudinal early lengthening (e) in relation to the mitral inflow (E) in acute coronary syndromes. We applied pulsed tissue Doppler to the septal, lateral, inferior, and anterior left ventricular basal walls of 160 patients with acute coronary syndromes and 60 control subjects. Maximum systolic and early diastolic velocities were lower for patient than for control walls (6.1 +/- 1.7 vs 7.9 +/- 1.4 cm/s, P <.0001, and 6.9 +/- 2.3 vs 10.0 +/- 2.3 cm/s, P <.0001, respectively) and e started later than E (12 +/- 30 vs 2 +/- 19 milliseconds later, P <.0001). All 3 variables related to the degree of visual left ventricular wall pathology. The intraindividual time range for all 4 e starts was wider for patients (43 +/- 27 vs 30 +/- 18 milliseconds, P <.0001). Our results show that pulsed tissue Doppler can identify a delayed and asynchronous initial wall lengthening in acute coronary syndromes.

- OBJECTIVE: To evaluate whether subgroups of patients with no chance of survival can be defined among patients with out-of-hospital cardiac arrest. PATIENTS: Patients in the Swedish cardiac arrest registry who fulfilled the following criteria were surveyed: cardiopulmonary resuscitation (CPR) was attempted; the arrest was not crew witnessed; and patients were found in a non-shockable rhythm. SETTING: Various ambulance organisations in Sweden. DESIGN: Prospective observational study. RESULTS: Among the 16,712 patients who fulfilled the inclusion criteria, the following factors were independently associated with a lower chance of survival one month after cardiac arrest: no bystander CPR; non-witnessed cardiac arrest; cardiac arrest occurring at home; increasing interval between call for and arrival of the ambulance; and increasing age. When these factors were considered simultaneously two groups with no survivors were defined. In both groups patients were found in a non-shockable rhythm, no bystander CPR was attempted, the arrest was non-witnessed, the arrest took place at home. In one group the interval between call for and arrival of ambulance exceeded 12 minutes. In the other group patients were older than 80 years and the interval between call for and arrival of the ambulance exceeded eight minutes. CONCLUSION: Among patients who had an out-of-hospital cardiac arrest and were found in a non-shockable rhythm the following factors were associated with a low chance of survival: no bystander CPR, non-witnessed cardiac arrest, the arrest took place at home, increasing interval between call for and arrival of ambulance, and increasing age. When these factors were considered simultaneously, groups with no survivors could be defined. In such groups the ambulance crew may refrain from starting CPR.

- OBJECTIVE: To describe the cause of death in the long term after coronary artery bypass grafting (CABG) with particular emphasis on cardiac death. PATIENTS AND SETTING: All the patients in western Sweden without simultaneous valve surgery and without previous CABG who underwent CABG in 1988-1991 in Goteborg, Sweden. DESIGN: Prospective, observational study for 10.6-13.6 years (i.e. until the end of 2001). Various factors contributing to death were described, with the emphasis on cardiac death. RESULTS: In all, 2000 patients were included in the survey. The all-cause mortality rate was 39%. Fifty-eight per cent of all deaths were judged as cardiac deaths. The most frequent cause of death was heart failure (65% among patients who died within 30 days after CABG and 36% among those who died >30 days after CABG). The second most common cause of death was myocardial infarction (56 and 29%, respectively), followed by cancer (0 and 24%, respectively), stroke (21 and 18%, respectively) and infection (8 and 11%, respectively). CONCLUSION: The factors most commonly contributing to death in the long term after CABG were, in order of frequency, heart failure, myocardial infarction, cancer, stroke and infection.

- AIM: To describe the change in the occurrence of ventricular fibrillation as initially observed arrhythmia among patients suffering from out-of-hospital cardiac arrest in Sweden. PATIENTS: All patients included in the Swedish cardiac arrest registry between 1991 until 2001. The registry covers 85% of the population in Sweden. METHODS: All patients with bystander witnessed out-of-hospital cardiac arrest included in the Swedish Cardiac Arrest Registry between 1991 and 2001 from the same ambulance organisation each year were included in the survey. RESULTS: Over 11 years, among patients in Sweden with a bystander witnessed out-of-hospital cardiac arrest in whom cardiopulmonary resuscitation (CPR) was attempted (n = 9666), the occurrence of ventricular fibrillation as the initially obseved arrhythmia decreased from 45% in 1991 to 28% in 2001 (P < 0.0001) if the arrest occurred at home, and from 57% to 41% if the arrest occurred outside home (P < 0.0001). This was found despite the fact that the proportion who received bystander CPR increased from 29% in 1991 to 39% in 2001 if the arrest occurred at home (P < 0.0001) and from 54% to 60% if the arrest occurred outside home (NS). There was a significant increase in age among patients with out-of-hospital cardiac arrest at home, no change in the estimated interval between collapse and call but an increase in the interval between call and arrival of the ambulance among patients with out-of-hospital cardiac arrest outside home. CONCLUSION: During 11 years in Sweden, there was a marked decrease in the proportion of patients found in ventricular fibrillation among patients with a bystander witnessed cardiac arrest regardless whether the arrest occurred at home or outside home. A modest increase in age and interval between call for, and arrival of, the ambulance was associated with these findings.

- AIM: To evaluate whether long-term treatment with a fixed low dose of warfarin in combination with aspirin improves the prognosis compared with aspirin treatment alone after an acute myocardial infarction (AMI). METHODS: Patients who were hospitalized for AMI were randomized to either 1.25mg of warfarin plus 75mg of aspirin (n=1659) daily or 75mg of aspirin alone (n=1641). The study was performed according to the PROBE (Prospective Open Treatment and Blinded End Point Evaluation) design and was conducted at 31 hospitals in Sweden. The median follow-up time was 5.0 years. In the aspirin+warfarin group, 30.2% were permanently withdrawn as opposed to 14.0% in the aspirin group (P<0.0001). Analyses were performed on an intention-to-treat basis. RESULTS: The combination of cardiovascular death, reinfarction or stroke was registered in 28.1% in the aspirin+warfarin group versus 28.8% in the aspirin group (NS). Cardiovascular deaths occurred in 14.2% in the aspirin+warfarin group vs 15.7% in the aspirin group (NS). Whereas no difference was found with regard to total mortality or reinfarction, those randomized to aspirin+warfarin had a reduced occurrence of stroke (4.7% vs 7.1%; P=0.004). The percentage of patients who suffered a serious bleed was 1.0% in the aspirin group vs 2.2% in the combination group (P=0.0006). CONCLUSION: A fixed low dose of warfarin added to aspirin in the long term after AMI did not reduce the combined risk of cardiovascular death, reinfarction or stroke. The results did, however, indicate that a fixed low dose of warfarin added to aspirin reduced the risk of stroke, but this was a secondary end point. The combination of aspirin and warfarin was associated with an increased risk of bleeding.

- Smoking is one of the major risk indicators for development of coronary artery disease, and smokers develop acute myocardial infarction (AMI) approximately a decade earlier than nonsmokers. In smokers with established coronary artery disease, quitting smoking has been associated with a more favorable prognosis. However, most of these studies comprised younger patients, the majority of whom were males.
