Hi Dr. Gopi, my dad currently has Coronary Heart Disease. He has a general Cardiologist ; However she told him that she will not perform a heart catherization anymore. That scares me because my dad is the type of person that nothing wont show up on the other cardio test, like EKG and others. The only way you can tell that my dad has a problem is through the Heart Catherization. My dad had a quadrouble bypass, and a lot of stents put in. So, my question is, should I find a interventional cardiologist or maybe a surgen cardiologist who has a higher level than a general cardiologist?
