AB  - OBJECTIVE: To evaluate the onset of exercise-induced interstitial pulmonary edema 
      in cardiac patients by high-resolution CT (HRCT). DESIGN: Prospective, normal 
      controlled. PARTICIPANTS: Thirty subjects divided into three groups: group 1--10 
      outpatients with chronic congestive heart failure (CCHF), New York Heart 
      Association (NYHA) class I; group 2--10 outpatients with CCHF, NYHA class II/III; 
      and group 3 (control)--10 normal subjects. METHOD: HRCT scans were obtained at 
      rest and 4, 8, 12, 16, and 20 min after progressive treadmill exercise test. 
      RESULTS: The following HRCT findings consistent with interstitial edema were 
      significantly different (p<0.05) in group 2 when compared with groups 1 and 3: 
      artery/bronchus ratio > 1 in the upper lobes, peripheral increase in the vascular 
      markings, interlobular septal thickening, and peribronchial "cuffing." These 
      differences were maximal at 12 min after exercise and returned to normal values 
      after 20 min. CONCLUSION: Interstitial pulmonary edema was present immediately 
      after exercise in CCHF patients. It may be important in the genesis of dyspnea of 
      these patients.
