I am new to this site found it browsing the web. I rec'd a letter from the VA stating that i was eligible for a Rating for Ischemic heart disease caused by exposure to agent orange. I have been 100% since 2003. I filed for heart disease in 1991 the letter said they knew of my filling and i would be paid back pay on the heart rating and it could go back to 1975. I had quadX4 1n 2003 but my medical records state that i had two previous heart attacks dates unknown. I was in the USMC 1967-1971 was wounded in RVN 1968 at the rockpile.Would like to hear from any one who served in the RVN.
