Guy Mayeda MD FACC (Fellow of the American College of Cardiology), FSCAI (Fellow of the Society for Cardiovascular Angiography and Interventions) is an interventional cardiovascular specialist with additional expertise in endovascular interventions for coronary artery disease, critical limb ischemia, dialysis access shunt failures and aortic aneurysms/dissections.

Dr. Mayeda has always been fascinated by the intellectual challenge and emotional rewards of the medical profession. He considers it both a privilege and a great responsibility to have patients and their families entrust their lives to the care of a physician, often times a complete stranger at the time of the initial consultation. He chose his specialty because cardiovascular disease remains the number one cause of death and disability in America, although recent advancements in medical research and technology have grown exponentially making it possible to successfully treat patients who had been previously diagnosed as “incurable.”

Dr. Mayeda is proud to be part of a hospital based team that provides care for patients who have been deemed too ill or high-risk for conventional medical therapy. This team has the unique ability to evaluate and plan interventions using a multispecialty approach that includes treatments for multi-vessel coronary artery disease, structural heart disease and various vascular maladies.

According to Dr. Mayeda, “the most gratifying aspect of interventional cardiology is the ability to quickly intervene and treat patients with acute life-threatening illnesses and restore them to their former functional status, often within a few days.”

Dr. Mayeda’s patients would be surprised to learn that both his parents were incarcerated in a Japanese-American relocation camp in Arkansas during World War II. His father enlisted in the U.S. Army after graduating from high school in the relocation camp and fought with the 442nd infantry in Italy. His parents’ sacrifice and hard work allowed Dr. Mayeda and his three siblings to attend college and post graduate education.

When he was younger, Dr. Mayeda competed in triathlons and judo but “that was many years ago!” One of his favorite past recognitions was for “Best Handwriting” among the hospital medical staff (pre-dating the introduction of the EHR).

September 07, 2021
The staff apparently failed to inform the doctor of the reason for my visit. I did not enjoy sitting in a very uncomfortable chair for an hour waiting to see him. I was on the point of leaving when he was fetched. Since he didn't know why I was there, he had to call me later with the results.

Yes Dr. Mayeda is the best doctor I've seen in my lifetime and particularly with Cardiology issues. He's treated me before ,he treated me well again that the other day so I have nothing but positive things to say about him and it's too bad that all the doctors aren't as good as he is, he's terrific okay, that's it. Goodbye.

I trust LA Cardiology Associates with my care. I am a nurse and a patient of them. I have worked with these MDs for 29 years and even when I left Good Sam, I kept my MDs to take care of me. They're a great team and patient oriented!
July 16, 2021
Very professional ??
July 13, 2021
Hi. I was satisfied with the way. I was treated by the doctor, himself and I couldn't ask for a better treatment.
July 09, 2021
I've been a patient of Dr. Mayeda's for 15 to 20 years. And there's never been a time when I felt like I was not well attended to, well treated, not cared for professionally, very much appreciate his efforts, and the efforts of all those in the office.
July 09, 2021
Scheduling was not quite organized. My appointment was set up 4 months before but when I arrived at the office, I was not on the Lists. So that they have to squeeze me in because I was already there. Also, 2 hours before I get a call from the office that my appointment was a tele med appointment. I insisted that I was not informed way ahead of time. Besides, I am already at the other side of their office having an Ultra sound, then see the doctor.
July 06, 2021
Yes, Dr. Mayeda has been my doctor for many years now and I can't say enough good things about him and his staff. They have given me, excellent care. And actually I think he's the reason that I'm still around. Thank you.
July 02, 2021
30 minute wait
June 28, 2021
Fast service.
June 25, 2021
Small glitch in appointment by person on phone who tried to cancel my xiopatch inappropriately. I had to strongly argue that I needed to have it when I did.
June 25, 2021
Everything was good about Dr. Mayeda, I love him so dearly, he have time and patience with me. I never had a problem with him. So if that's all you know, I've been going to him over 13 years, about 14 years now, maybe longer than that, but he's, he's a good doctor, very good doctor.
June 25, 2021
This was my first office visit,since hospital & office changes I wasn't aware of my previous information not all saved, this delayed patients appointment times! I felt that was unprofessional of not getting a " heads up:, before being there!
June 22, 2021

The office at wilshire was difficult when it comes with parking. We waited3 hrs for the Dr to see us. And it was only a 5 mins chat with the Dr. He was nice and respectful but it wasn't a good office visit experience.
May 28, 2021
Dr was overbooked n we saw a nurse practitioner first. I waited 2 1/2 hours n if I hadn't complained twice I don't know if I would have had to wait longer. Not the Drs fault but how PIH is scheduling his patients. And I came to see the Dr not a nurse practitioner.
May 28, 2021
The Assistant to Dr. Mayeda who attended me was very professional, efficient and attentive.
May 18, 2021
The transfer of records from PIH taking over. USC care is very cumbersome. I had to fill out information that was already on file. So there needs to be a better transition of data during this takeover of PIH / you see kicks. So please improve your technology and your transfer of data. Thank you.
May 18, 2021
The doctor and staff are very professional and courteous. Doctor is very knowledgeable about the patient. The staff will try their vet best to aid the patient in any way they can. This doctor and staff made for a very pleasant visit.
