Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding similar study ___ ___ . The heart is moderately enlarged . The configuration indicates a left ventricular prominence to the left and posteriorly . This finding in conjunction with the generally widened and elongated thoracic aorta is suggestive of systemic hypertension . This cardiac enlargement is rather similar to what has been noticed on the previous chest examination ___ ___ . The pulmonary vasculature on the other hand has undergone a change in it , much as the vasculature is more plethoric and shows perivascular haze consistent with some mild degree of interstitial edema . In addition , the lateral pleural sinuses are now blunted by small amounts of pleural effusion that extend into the posterior pleural sinuses as seen on the lateral view . There is no evidence of new discrete pulmonary parenchymal infiltrates and no pneumothorax can be identified in the apical area .
    OUTPUT:
    
Persistent moderate degree of cardiomegaly , most likely related to systemic hypertension . Since the preceding examination , the patient has developed an episode of interstitial edema and mild bilateral pleural effusions . This finding indicates mild degree of chronic CHF , but there is no evidence of new acute pneumonic infiltrate .
