Abstract

Twenty patients with chronic obstructive lung disease were studied. The spirometry demonstrated predominantly reduction of vital capacity with signs of pulmonary hyperinflation. Obstruction of the proximal and distal airways was also noted. Total pulmonary resistance and static lung compliance were increased in the majority of these patients. Hypoxemia was present in the entire group, with no carbon dioxide retention. Various degrees of pulmonary artery dilatation were detected on the radioisotopic examination, suggesting pulmonary hypertension, confirmed by the increased mean pulmonary transit time. Regional disturbance of myocardial motility of the right ventricle was observed in 90% of the patients, being severe in 15%. The end-systolic volume was increased in 95% of the patients and the end-diastolic in 55%. These changes represent an initial functional disturbance, which does not allow to draw conclusions about reduction of the cardiac output or the ejection fraction. Left ventricular motility was normal in 85% of the patients, reduced in 15% and severely reduced in only one patient. Left ventricular volume was discrete or moderately increased in six patients (20%). The ejection fraction was decreased in one patient (5%). The increased ejection fraction observed in three patients is likely a consequence of a rise in the ejected  More>>

Taking into consideration the patients' age, it could be concluded that aortosclerosis with structural changes of its caliber is the cause of the elongation. (author).}
