Diagnostic Testing

Diagnostic Testing One of the most important facets of cardiovascular health is educating yourself as much as possible. Education not only means researching and understanding different heart-healthy lifestyle choices to make, but also visiting your cardiologist regularly for checkups, and diagnostic measures in the event you might feel off in any way. All too often, cardiovascular issues go undiagnosed, and therefore untreated, in even the youngest of individuals. And sometimes, one checkup could have made all the difference in your health.

So don’t delay, Dr. Kalafatic and his team offer a wide variety of diagnostic treatment methods to help patients of all ages, diagnose and better understand issues or concerns they might be experiencing.

Dr. Kalafatic is an excellent cardiologist! Gave me tons of advice on my diet and told me some ways I could be more active during the day, without having to change my schedule too much. I did a full lipid panel and cholesterol test, he recommended some [prescription medication to help lower my cholesterol while also giving me some pointers on keeping things in check naturally as well. Highly Recommended!! Plus he speaks Spanish too! So I’m definitely making an appointment for my mother (who doesn’t speak much English) as soon as she gets back from Nicaragua!

I called the doctor’s office just to let him know that I would be 15 minutes late. Once I arrived, I was seen right away by the medical assistant who was very professional and made me feel comfortable on my first visit. Dr. Kalafatic examined me and asked all the right questions. Never was there a rush by either Dr. Kalafatic or his staff. I have scheduled a follow up appointment. 5 Stars all around.

Luis H.

The wait was maybe 15mins… if that much. He was very thorough. He explained everything in detail and his bedside manner was great! He is very genuine. I high recommend him!

Nicole W.

Verified Patient

I used to be a patient of Dr. Kalafatic…I don’t live in Bronx, NY anymore. I think you might be related to the doctor I used to see. He was much older than you. It’s good to know that his offspring took over the practice and that you’re offering great medical services too. 😊

My mother had a stroke 4 years ago, and it took her years to get her movement back and be able to talk 100% but thankfully she’s a lot better now. During that time, she had to be taken to her cardiologist Dr. Kalafatic’s office. And despite her limited mobility and issues with speaking clearly, Dr. Kalafatic and his staff made each appointment an absolute breeze! No hassles whatsoever, I never had to wait long (as I was often on my lunch break at work taking my mom). Thanks Dr. K!

Ricky U.

I got a referral to see Dr. Kalafatic for an echocardiogram and an EKG from my doctor. And while it was just a checkup, because of some issues I was having I must say it was a great experience. Showing up to my appointment early, I never thought I would be seen early! That was a huge plus right from the beginning. Then throughout the time I was there, from the staff to the doctor himself, everyone was friendly and made me feel super comfortable. I have a follow-up appointment for a stress test in a month or so, and I got to say, I’m not dreading it in the least! If you need any cardiology testing done at all, definitely ask about Dr. Kalafatic in the Bronx!
