[Influence of atmospheric pressure fluctuation on condition of patients with cor pulmonale]

Based on investigation of 632 patients with cor pulmonale, we found that there were a close corresponding relationship of attack, exacerbation and death of patients to negative variation of daily atmospheric pressure. It was more obvious that the persistent and significant decrease in atmospheric pressure could influence the patient situation. The disease attacks usually appeared behind in negative variation of pressure changes, however, the death did before them. The mechanism of influences of atmospheric pressure changes on situation of patients with cor pulmonale were discussed preliminarily. The authors point out that the disease condition might be predicted by forecast and should take preventive measures to avoid it in advance.
