And no doubtedly, I believe Dr. Imbrie saved my life because I lost my brother at 53 and my father had a major heart attack at 53.

And he was very thorough, and I truly believe he saved my life.

  • Dr. Imbrie took the time to locate additional information regarding prescription options available to me and provided me with a clear explanation.

    2026-06-03

  • While Dr. Imbrie was somewhat personable, he contradicted information that my regular cardiologist (who I trust more than almost any other doctor I've ever seen) has explained to me, which made me hesitant. Then he basically said that the test he would do would prove that I didn't have a condition that several other doctors believe I may have the early stages of, so right from the beginning he was more or less dismissing mine and my doctors' concerns and saying I didn't have something without having even done the test yet. And then when he was explaining how the test was administered, he was making decisions that concerned me, and did not make me feel comfortable having him do the test. He's probably a great doctor for other people with other conditions, but he was not a good fit for me.
