My grandfather died (while in sleep ) due to heart attack.(Age 60)

My father died at third heart attack.(Age 66)

My sister has undergone angioplasti (Age 60)

My another sister has High B.P. problem(Age 58)

I have underwent Bypass Surgery (Age 54) recently.

Is it that heart problem is hereditory?
