(Review on Facebook) “Hello , This is a great test (Coronary Calcium Score) to determine the risk of a CV event before it happens . I had this test , cholesterol was high , have been on meds and it went down , did very well on stress tests , but just was not feeling well - Dr D’Agate scheduled the calcium test and my score was very high - 659 .... right after he then scheduled me to have a catherization and the results were I had severe blockage . I turn I had bypass surgery and it has been 18 months since . The calcium test was very important because without it my stress test and cholesterol levels seemed ok . Please listen to the cardiologist as they have all the tools needed to further determine the issues with each patient , I cannot thank Suffolk Heart Group enough and Dr D’Agate as I probably would not be writing this today . Thank you for reading and hope this helps who ever is questioning the Calcium Test“ – Gary “When my AFB was detected, Dr. Ladinksy said that he would set me up with the very best cardiology team. Now I know what he already knew. I sincerely thank you and look forward to our future meetings. Dear Dr. A’gate, Thanks so much for helping me through these challenging days. Your calm, confident, and gentle approach and guidance eased my nervousness. In short, you helped to save my life, and I am forever grateful. “ – Jack “Dr. D'Agate & staff are wonderful.

(Review on Facebook) “My husband and I are both patients for over 20 years. We would never go anywhere else.In 1999, they performed a quadruple bypass on my husband, who had multiple blockages. To this day, he has never had a heart attack due to their excellent care. Since Dr. D'Agate joined the practice, he has saved me twice. I went to the office complaining of chest pain and he sent me immediately to the hospital, where I ended up having stents put in. This happened twice. I would never consider going to any other doctor. He is extremely knowledgeable, kind and funny. He is unlike any other cardiologist I have ever been to. All the doctors in this group are exceptional. “ – Karen V. (Review on Facebook) “Dr. Agate is a real person — not just a face behind a clipboard reading test results and pushing pills. He asked about my lifestyle, and recommended achievable goals for my overall health. “ – Linda A. (Review on Facebook) “The Doctors are up to date on up to date on the all the current procedures relevant to all phases of care for the heart.The doctors are top notch Dr D'Agate who is the first physician you see is very pleasant and knowledgeable and puts you at ease and reduces any stress or anxiety you may have about a heart issue you might be experiencing. I have seen all of the doctors in this practice and without their expertise and in all phases of heart issues I probably wouldn't be writing this right now. Kudos to the physicians and staff at Suffolk Heart. Now go make an appointment you won't be sorry. JG “ – J.G.

Dr D’Agate recommended Dr Durbin of St Frances to do the procedure again 6 months later? It was a success! No more fluid the last 2years and my son has lost 40 lbs!
