Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Comparison is made with the next preceding similar study of ___ . Moderate cardiac enlargement remains as described earlier . There is a relative prominence of the left ventricular contour , finding which in conjunction with the generally widened and elongated thoracic aorta is compatible with systemic hypertension . All these findings are unchanged and presently there is no evidence of pulmonary vascular congestion . Relatively low positioned and somewhat flattened diaphragms are indicative of COPD and there exist some linear densities on the bases compatible with increased interstitial fibrosis . There is , however , no evidence of new acute pulmonary infiltrates and no evidence of pleural effusions in the lateral or posterior pleural sinuses . Previously described local rib changes in the upper axillary area on the right side persist and are compatible with old but no new skeletal injuries . The retrocardiac rounded density in the midline compatible with the previously described moderately sized apparently fixed hiatal hernia .
    OUTPUT:
    
Stable chest findings with moderate cardiac enlargement . No evidence of acute pulmonary congestion . No evidence of new acute pulmonary infiltrates .
