White matter disease in magnetic resonance imaging predicts cerebral complications after coronary artery bypass grafting.

Background: The aim of the present study was to assess neurologic and neuropsychologic complications in 104 patients randomized to coronary artery bypass grafting or spinal cord stimulation. An additional objective of the study was to assess whether preoperative white matter disease might predict cerebral complications, as previous studies have shown that there is a relationship between white matter disease and neuropsychologic decline after coronary artery bypass grafting.

Methods: The patients were subjected to neurologic examination before and six months after intervention.

Temporary cessation of spinal cord stimulation in angina pectoris-effects on symptoms and evaluation of long-term effect determinants.

Background: Spinal cord stimulation (SCS) has been used since 1985 for patients with refractory angina pectoris. Spinal cord stimulation has anti-ischaemic effects and reduces angina effectively. After long-term treatment, temporary cessation of stimulation may occur due to SCS battery depletion or electrode fracture.

Long-term effects of spinal cord stimulation and coronary artery bypass grafting on quality of life and survival in the ESBY study.

Aims: To assess the long-term outcome regarding quality of life and survival in patients who were included in the ESBY study 1992-1995. The ESBY study (Electrical Stimulation versus Coronary Artery Bypass Surgery in Severe Angina Pectoris) included 104 patients-with severe angina, increased surgical risk and no prognostic benefits from revascularization-randomized to coronary artery bypass grafting or spinal cord stimulation.

Methods And Results: The ESBY patients' quality of life was analysed using two questionnaires, and 5-year mortality was assessed.

[Treatment guidelines for refractory angina pectoris now available. Therapeutic methods varying between behavior therapy and heart transplantation].

Refractory angina pectoris is defined as severe angina despite optimal medical and surgical/invasive treatment (CABG, PTCA). The epidemiology of this condition is unknown. The estimated yearly incidence is 2,000 patients in Sweden and 30,000-50,000 patients in Europe.
