I've had asthma since 2000 (am 77yo). High humidity really sets off the coughing and fluid in my lungs. I recently had an ECO and discovered progressive aortic valve restriction. Symptoms are very similar to asthma. I'm having an angiogram Friday to understand the extent of restriction and course of action. The bottom line is to have your cardiologist do an ECO to rule out aortic valve concerns. The earlier the better.
