Your PCP can send you for the tests, but if my life depended on it I would pay for the private care. I am 60% for heart and I have never seen a cardiologist. My experience with the VA was that they gave me tests that contradicted each other and they never followed up on it. My other experience is that the VA will wait until you have a heart attack before they even talk to you about your heart. I know we all get screwed to an extent because the VA is so cheap, but you have to protect yourself since they won't. I mean if you are 100% vet the VA is just waiting for you to die so they can take you off the ledger. We are dead men walking to them.
