Primary objectives of this dissertation work were the evaluation of the access to the post-healing treatment and its prognostic significance after heart-thorax-surgical or cardiological hospitalization in patients with coronary heart disease, as a potential aspect for the high cardiovascular mortality in Saxony-Anhalt. Of the 315 patients who died during the observation period, 223 (70.8%) died of heart disease. This dissertation shows a statistically significant reduction of mortality by 21.7% in favor of the rehabilitation patient collective. Rehabilitation for cardiac patients was associated with lower mortality. Fewer patients underwent rehabilitation in this study than in other, comparable studies. Those who did not were older and had a greater burden of accompanying disease.
