Hello Hypertrophic cardiomyopathy ( two types obstructive and non-obstructive) is characterized by left ventricular hypertrophy , typically of a non-dilated chamber , without obvious cause such as hypertension or aortic stenosis. Now about the treatment point of view . Condition may deteriorate just after physical exertion , competitive sports and probably strenuous activity , so these should be avoided in any condition. Dehydration should be avoided in any condition and DIURETICS ( LASIX in your case) should be used with great caution. Beta adrenergic blockers are often used and ameliorates angina pectoris ( as you mentioned that there is shortness of breath and fullness in stomach or abdomen ) , so these symptoms may subsides in your case. Because this disease is a complex form so it is very hard to advise on this issue . In my opinion consult one more CARDIOLOGIST and get his 2nd opinion about use of lasix and pitting edema . All these things I mentioned in your case because diagnosis is already established . Hope this information will helps you. Good luck.
