Regional pulmonary ventilation in patients with ischemic heart disease

: The state of regional pulmonary ventilation was studied in 41 patients with coronary heart disease (CHD) of various degrees of myocardial affection using pulmophonography. A total degree of ventilation irregularity in the CHD patients did not differ from that of healthy individuals. An increase in this index was noted for the right lung in all the patients. The most noticeable changes of regional pulmonary ventilation were observed in patients with macrofocal cardiosclerosis and consequent cardiac aneurysm, and were expressed in an increase in ventilation of the right lung upper zone and its decrease in the left lung upper zone and in the middle zone of both lungs.
