[The incidence of fatal lung emboli with special reference to the underlying disease and the effect of weather].

The frequency of the fatal pulmonary embolism in the autopsy material of Rostock University undergoes greater variations. After an increase of the incidence in connection with hyperalimentation and increase of age to the twofold to threefold between 1922 and 1974 as possible sequel of a prophylaxis of thrombosis a decrease of maximally 12.4 to 8.2% is to be established. The average age is 67.8 years, females are more affected to the relation of 1:1.6. Clinically the diagnosis of causes of death was exactly made in 25.9%. In the relation of causes dominate basic diseases of the cardiovascular and respiratory system with disturbances of the haemodynamics, malignant tumours without significant preference of certain organ carcinomas and infectious-toxic complications. A conspicuous accumulation concerned the chronic respiratory syndrome, often a polypathia existed. In the region of the coast of the Baltic Sea pulmonary embolisms appeared statistically significantly more frequently in fine weather phases and at beginning fine weather, respectively, with indifferent or tendencially rising global radiation on the day of the event and particularly in winter season. An influence of passages of weather fronts could not be established.
