[The clinical course of end stage heart disease in 152 patients qualified for heart transplantation in a four year observation].

Unlabelled: The aim of the study was to analyse the clinical course of pts with end stage disease (ESD) in the period of four years. The study population consisted of 152 pts (132 males, 20 females) at the age of 17-66 years (mean = 48.8 year SD = 9.1) primarily qualified to the heart transplantation (HTX). We analysed the ethiology of cardiac failure, the NYHA class of circulation insufficiency, frequency of occurrence of cardiac arrhythmias and conduction system disturbances in 24-hour ecg monitoring, and the pharmacotherapy efficacy. An ischemic ethiology of cardiac failure we found in 102 pts, cardiomyopathy (idiopathic, hypertrophic or postinfectious) in 46 and unoperable valvular disease--in 4. Ten pts were in II NYHA class, 112 in III, and 30 in IV. Left ventricular ejection fraction (echo assessed) ranged from 11% to 40%(mean = 24.9%), LVEDd = 46-111 mm (mean = 80.9 mm), LVESd = 34-83.5 mm(mean = 63 mm). We found IVa class by Lown ventricular arrhythmias (in Holter monitoring) in 38 pts and IVb in 78. Fifty six pts were treated with amiodarone, 10--with beta-blockers and 11 with sotalol. 19 pts were treated by permanent cardiac pacing during the waiting period, 2 ones--by PTCA, 2--by CABG, three ones--by dynamic cardiomyoplasty, and one--by partial aneurysmectomy. One pt was treated by CABG and automatic cardioverter-defibrilator implantation. In 5 cases HTX was delayed because of the positive effect of pharmacotherapy. In assessed period HTX were performed in 64 cases, 31 pts died and 43 are still waiting for the procedure.

Conclusions: During the 4-year period HTX were performed in 42% of waiting pts. Mortality in this group was 38.2%. In 9 pts (5.9%) the alternative methods of surgical treatment were applicable. In 5 pts (3.9) the decision about HTX was delayed because of the positive change of the clinical status. This fact confirms the necessity of the waiting list verification.
