Hi thanks for contacting HCM... Noted you have excess cough.... So first respiratory causes needs to be investigated. Here it might be bronchitis or chronic obstructive pulmonary disease or any restrictive disease.... It could be allergic condition like asthma also So investigate with following...... -respiratory physical examination -auscultation -chest x ray - pulmonary function test If you have acid reflux or gastritis then also irritative cough can occur. If still cause not identifiable cardiac causes ruled out by ECG or echo. Avoid smoking..... Keeping these in mind consult physician. Take care. Dr.Parth
