title: Heart transplantation in Finland 1985-1995.
abstract: OBJECTIVE
  Since improved immunosuppression in the 1980's, heart transplantation is a well established procedure to treat patients with end-stage heart failure. The first heart transplantation in Finland was performed in 1985. Since then the activity has gradually increased to a level of about 25 annual transplants. The aim of this report is to sum up the clinical experience during the first 11 years.
  
  
  METHODS
  From February 1985 till the end of 1995, 190 heart transplantations were performed in our institution. There were 176 males and 14 females ranging from 15 to 62 (mean 42.2) years of age. End-stage preoperative cardiac disease was dilating cardiomyopathy in 108 cases, coronary artery disease in 65 cases, valvular disease in 12 cases and congenital heart disease in five cases.
  
  
  RESULTS
  The 30-day hospital mortality was 29 out of 190 (15.2%). The actuarial survival was 77% at one year, 75% at two years and 73% at 10 years. The most common causes of death were rejection (11 cases), graft failure (11 cases), abdominal complications (six cases) and cytomegalovirus (CMV) infection (four cases). A total of 87 rejection episodes occurred in 53 patients consisting 28 per cent of patients. 44 rejections occurred within three months post transplantation. Significant infections were noted in 198 instances in 97 patients. These were of bacterial origin in 92, viral in 48, fungal in 12 and protozoal in 10 cases, and 36 such infections which responded to antibiotics favourably but in which the microbe remained unidentified. 138 infections (i.e. 80%) occurred within 6 months post transplantation. In viral infections cytomegalovirus (CMV) predominated (29 out of 48). The CMV infection was significantly milder in patients who were seropositive preoperatively than in preoperatively seronegative patients with seropositive donors. CMV infection was associated with increased risk of post-transplant coronary artery disease. Three years after transplantation some restoration of sympathetic nervous response was observed at orthostatic test in heart rate and blood pressure.
  
  
  CONCLUSIONS
  It can be concluded that 1) if a patient survives the three immediate postoperative months, his prognosis is good for the forthcoming years, 2) clinically significant rejections occur in less than one third of the patients, 3) cytomegalovirus is the most harmful agent post transplantation and a risk factor for post-transplant coronary artery disease and that 4) some restoration of sympathetic nervous control of the heart occurs within three years after transplantation.
