question: Hi Dr. A few days back had chronic cough and wheezing. The wheezing got better with asthama medications and puff but the cough persisted. on taking a x-ray and other blood tests dr concluded acute broncitis and put me on medication. The x-ray also showed mild cardiomelagy with slightly prominent pulmonary vasculature. Iam really scared as the dr has reffered me to a cardiac specialist. Is this very serious?
