  • Thoracic epidural anaesthesia in patients with unstable angina pectoris

    • The effect of high thoracic epidural anaesthesia with intermittent epidural bolus injections of bupivacaine (2.5 or 5 mg ml-1) was studied in 28 patients with unstable angina pectoris. The majority of the patients had a history of previous acute myocardial infarction(s) and/or angina pectoris and severe coronary artery disease. All patients were treated wth nitroglycerin infusion for gt;24 h and were included in the study if they had chest pain, not caused by acute myocardial infarction, at bed rest or recurrent anginal pain at rest < 2 days after infarction. 4.4 ± 0.3 ml of bupivacaine induced a blockade of the upper seven sympathetic segments ( Th1-7) for 98 ± 9min. Heart rate decreased significantly from 70 ± 3 to 64 ± 3 beats min-1 while blood pressure was unaffected by thoracic epidural anaesthesia. In 27 patients (96%) the anaesthesia induced complete analgesia. Nitroglycerin infusion was discontinued definitely within 3 h in 26 patients (93%) and pain was thereafter controlled by means of thoracic epidural anaesthesia as the sole treatment in 23 patients (82%) and as the major treatment in 25 patients (89%). Twenty-one patients (75%) were fully mobilized and stabilized. Treatment with thoracic epidural anaesthesia lasted for 6.0 ± 1.1 days. The number of daily epidural injections decreased significantly with time from 2.7 ±0.3 the first day to 0.9 ± 0.3 the fourth day (P>0.01, n = 19). Two patients developed acute myocardial infarction during the anaesthesia treatment period, and one of these patients died. Exercise stress testing was performed on eight patients three to five days after the start of thoracic epidural anaesthesia. At a comparable workload, ST-segment depression was significantly (P>0.05) less pronounced during anaesthesia ( − 0.6 ± 0.1 mm) compared with control ( − 1.3 ± 0.2mm). The respective heart rate values were 95 ± 7 and 107 ± 7 beats min -1 (P > 0.05), while systolic or diastolic blood pressure did not differ between the two conditions. We conclude that blockade of cardiac sympathetic afferents and efferents by means of thoracic epidural anaesthesia can effectively treat pain and stabilize patients with unstable angina pectoris refractory to medical treatment. Furthermore, thoracic epidural anaesthesia attenuates stress-induced myocardial ischaemia; thus, it may be an efficient supplementary treatment for the control of pain and for stabilizing patients with unstable angina pectoris during diagnostic procedures and prior to coronary surgery or angioplasty.

  • Follow-up by repeated signal-averaged surface QRS in patients with the syndrome of arrhythmogenic right ventricular dysplasia
  • 1989
  • Ingår i: European Heart Journal. - 0195-668X .- 1522-9645. ; 10:suppl D, s. 54-60
  • Tidskriftsartikel (refereegranskat)abstract
    • Repeated signal-averaged surface electrocardiograms were recorded with a mean interval of 32·5 months (range 14 to 55 months) in 12 patients with the syndrome of arrhythmogenic right ventricular dysplasia (ARVD). The mean differences in the amplitude and duration of the filtered QRS complex (FQRS), the root mean square voltage of the last 40 ms of the FQRS and the duration of the terminal potentials of less than 25 µV were not statistically significant between the recordings. A wide spectrum of changes in the voltage and duration of the terminal potentials was observed, irrespective of the clinical susceptibility to ventricular tachycardia. Three patients developed changes suggesting a progression, with a decreased voltage and prolonged duration of the terminal potentials, and four patients showed the opposite pattern. In five patients the signals were stationary. It is concluded that the properties of late potentials may change with time in patients with ARVD. Follow-up by repeated signal-averaged QRS does not appear to be useful in predicting the susceptibility to ventricular tachycardia in ARVD. Its application in predicting and following progressive right ventricular morphological changes remains to be determined.

  • Quality of life five years after myocardial infarction
  • 1989
  • Ingår i: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 10:5, s. 464-472
  • Tidskriftsartikel (refereegranskat)abstract
    • In 539 patients 5 years after myocardial infarction (MI), quality of life and factors influencing life quality were studied. All patients originally participated in an early intervention trial with metoprolol. A cardiac follow-up questionnaire and the Nottingham Health Profile were answered by 82%. In the former, information about subjective symptoms, smoking, work and current medication was obtained; the latter described health-related quality of life in terms of energy, sleep, emotions, mobility, pain and social isolation. The rate of and the reasons for rehospitalization were registered in the patients' records. The MI patients reported a comparatively high quality of life. Compared with ‘normal’ population, a decrease was noted in energy, sleep and mobility, and in sex life, hobby-activity and holiday activity. A non-parametric multivariate analysis disclosed that dyspnoea, angina pectoris and anxiety were closely associated with decreased quality of life. In conclusion, 5 years after MI most patients seemed well-adjusted. Impaired quality of life was reported by patients suffering from angina pectoris, dyspnoea and emotional distress. No relationship was found between health-related quality of life and the beta blocker, metoprolol, which was the most frequently used drug.
