In the United States, heart donor availability has increasingly failed to keep pace with rising demand. Transplant data were obtained from the United Network for Organ Sharing for 1988, 1989, and 1990 and by survey of 50 heart transplantation centers, which performed 1932 transplantations between 1983 and 1989. According to the United Network for Organ Sharing, 512 patients on the waiting list died in 1988; 527, in 1989; 650, in 1990, and if present trends continue more than 800 will have died in 1991. Similar numbers of patients were inactivated or removed from the list each year. Only 49% of patients (1647 of 3390) on the heart transplant waiting list at some time in 1988 underwent the procedure in that year. For 1989 the figure fell to 42% (1630 of 3915 patients). Survey data revealed a threefold increase in the ratio of the number of patients who died/number of patients who underwent transplantation from 0.07 in 1983 to 0.21 in 1989 and in the ratio (number of patients who died+number of patients who were removed from the list)/number of patients who underwent transplantation from 0.12 in 1983 to 0.38 in 1989. The major causes of death among waiting patients were congestive heart failure (46%) and arrhythmia (29%). From 1983 to 1989, 55% (134 of 243) of those patients with documented urgency status died in the intensive care unit; 45% (109 of 243) died elsewhere. Waiting time for patients dying in the intensive care unit rose from 10.7 days in 1985 to 50.3 days in 1989; patients dying out of the intensive care unit waited 103.7 days in 1985 and 85.6 days in 1989. In conclusion, the number and proportion of potential recipients who die awaiting heart transplantation is increasing every year. Congestive heart failure and arrhythmia are the major causes of death, and similar numbers of patients die in and out of the intensive care unit. |
