Hello.Welcome to HCM forum.If any heart patient can walk two flight of stairs with brisk pace without any chest pain
or shortness of breath
or discomfort then it means you can enjoy your sex life normally.Sex is prohibited in patients who have severe heart problems or who can't walk few steps normally without any dysnoea. Moreover very very few heart patients have died because of heart attack
during sex and even those deaths have occurred to those people who were doing sex under the high dose of drugs like VIAGRA
.So relax and if you don't have any major problem,enjoy your sex life.Thanks and good luck.
