My husband, age 52, spit up foamy pink saliva this morning.  He says it is intermittent but has been happening for in excess of a year.  He has HBP controlled by Benicar.  He claims he has no other symptoms but I am concerned it is a potential heart/lung issue.  Recommendations?
Thanks for your question on Chat Doctor. I can understand your concern. Pink frothy saliva in morning is a symptom of possible early heart failure or bronchitis. Since he is already having hypertension, you should first rule out heart diseases. So get done blood pressure monitoring, ECG, 2d echo and stress test. If all these are normal then no need to worry about heart diseases. Also get done chest x-ray and PFT (Pulmonary Function Test) for the diagnosis of bronchitis. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
