- Contraction of longitudinal and subendocardial myocardial muscle fibres is reflected in descent of the atrioventricular (AV) plane. The aim was therefore to determine whether beta blocker treatment with prolongation of diastole might result in improved function as reflected by AV plane movements in patients with chronic heart failure.Double blind, randomised, placebo controlled and open intervention study.University hospital.Patients with congestive heart failure: placebo controlled (n = 26) and an open protocol (n = 15).12 months of metoprolol treatment.Short axis and long axis echocardiography, invasive haemodynamics, radionuclide angiography.Recovery of systolic and diastolic function during metoprolol treatment was reflected by early changes in mean (SD) AV plane amplitude, from 5.3 (2.0)% to 7.1 (3.2)% and 7.8 (3. 1)% (at 3 and 12 months, respectively; p < 0.05). In a multivariate analysis, only the change in AV plane amplitude by three months was independently associated with improvement in pulmonary capillary wedge pressure by six months (r = 0.80, p = 0.017). Change in AV plane amplitude by three months was also a better predictor of improvement in ejection fraction by 12 months (r = 0.78, p < 0.001) than changes in radionuclide ejection fraction by three months (r = 0.34, p = 0.049).Improvement in longitudinal contraction was closely associated with a decrease in left ventricular filling pressure during metoprolol treatment. This association was stronger than changes in short axis performance or radionuclide ejection fraction, emphasising the importance of AV plane motion for left ventricular filling and systolic performance in patients with heart failure.

- 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 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.

- 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.

- To describe the impact of a history of diabetes mellitus on the improvement of symptoms and various aspects of quality of life (QoL) during 5 years after coronary artery bypass grafting (CABG). Patients who underwent CABG between 1988 and 1991 in western Sweden were approached with an inquiry prior to surgery and 5 years after the operation. QoL was estimated with three different instruments: Physical Activity Score (PAS), Nottingham Health Profile (NHP) and Psychological General Well-Being (PGWB) index. 876 patients participated in the evaluation, of whom 87 (10%) had a history of diabetes. Symptoms of dyspnea and chest pain improved both in diabetic and non-diabetic patients. Diabetic patients scored worse than non-diabetic patients both prior to and 5 years after CABG, but without any major difference in improvement between the two groups with all three measures of QoL. PAS tended to improve more in non-diabetic than in diabetic patients, whereas improvement in NHP and PGWB was similar regardless of a history of diabetes. Diabetic patients differ from non-diabetic patients having an inferior QoL both prior to and 5 years after CABG. Both diabetic and non-diabetic patients improve in symptoms and QoL after the operation. In some aspects improvement tended to be less marked in the diabetic patients but on the whole improvement was similar compared to non-diabetic patients.

- The aim of this study was to describe the relief of symptoms and improvement in other aspects of health-related quality of life 5 years after coronary artery by-pass grafting in relation to age. Patients in western Sweden were approached with an inquiry prior to surgery and 5 years after the operation. Health-related quality of life was estimated with 3 different instruments: Physical Activity Score (PAS), Nottingham Health Profile (NHP), Psychological General Well-Being Index (PGWB). Prior to surgery patients were approached either in the ward or by post and 5 years after surgery they were approached by post. A total of 1719 patients were available for the survey, of whom 876 (51%) responded to the survey both prior to and after 5 years. Among the 876 respondents 287 were <60 years, 331 were 60-67 years and 258 were >67 years. In terms of physical activity, chest pain and dyspnoea, a similar improvement was observed regardless of age. In terms of health-related quality of life questionnaires, there was an inverse association between age and improvement when using PAS and a similar trend was observed with NHP and PGWB. In conclusion, 5 years after coronary artery bypass grafting relief of symptoms and improvement in physical activity was not associated with age, whereas improvement in other aspects of health-related quality of life tended to be less marked in elderly people. Overall age seemed to have a small impact on the improved well-being 5 years after coronary surgery. However, due to the limited response rate the results may not be applicable to a non-selected coronary artery bypass grafting population.
