Abstract

The accessibility and success of cardiac transplantation promotes transplantation for a broad range of recipients, including those requiring intravenous inotropes or mechanical-assist devices. To determine if survival is dependent on preoperative requirements for hemodynamic support, we studied 230 patients who underwent transplant at the Loyola, Stanford, and UTAH programs from December 1, 1984 through November 30, 1986, and who were followed up for 34 months postoperatively. Group 1 (n = 132 of 230, 57%) patients required only oral medical therapy to maintain hemodynamic compensation; Group 2 (n = 69 of 230, 30%) patients were dependent on intravenous inotropic support; and Group 3 (n = 29 of 230, 13%) patients required mechanical assistance. Pretransplant characteristics showed that dilated cardiomyopathy was more common in Group 2 patients, and lower cardiac index and ejection fraction were more prevalent in Group 3 patients as expected. Although survival was lower in Group 3 only at 1 month (Group 1, 98.5%; Group 2, 92.8%; and Group 3, 86.2%; p less than 0.01), the survival advantage in Groups 1 and 2 was lost by 3 months, with 1-year survival rates of 88.6% in Group 1, 81.2% in Group 2, and 82.8% in Group 3. Allograft survival and cause of death were not different among the three groups. Acute rejection occurred at a lower monthly frequency in the first 4 months in Group 3 (Group 1, 0.47 +/- 0.03; Group 2, 0.47 +/- 0.05; and Group 3, 0.29 +/- 0.06; p less than 0.01), whereas infectious complications occurred at similar frequencies.(ABSTRACT TRUNCATED AT 250 WORDS)
