about us

Stat! Cardiologist is a fast growing internal medicine & cardiac services company in the Chicago suburbs.

Founded in 2017 by Dr. Saifullah Nasir, we operate 4 clinic sites in Chicago and suburbs (including Niles, Schaumburg, and Oak Brook). Our focus is on providing exceptional heart care to our patients. Besides receiving Cardiology training, Dr. Nasir is also a Board Certified Internal Medicine doctor.  If you already have a primary care provider, we will work with your primary care provider to coordinate your care.  If you do not have one, we can be your primary care provider as well.  Our work is efficient, prompt and personalized.

“I make it a personal mission to advocate for all my patients.  My patients are just like my family and have access to me via cell phone 24/7.”
-Dr. Nasir

Dr. Saifullah Nasir completed medical school and residency in Internal Medicine at Baylor College of Medicine. He then completed Cardiovascular Disease training at Lutheran General Hospital in Park Ridge, IL. He was selected as Chief Cardiology Fellow during his training. Dr. Nasir received hands-on training in general cardiology, nuclear medicine, vascular medicine, and echocardiography.


Besides excellent cardiology care, we focus on delivering unique advantages to our business partners. This allows them to thrive in a very competitive healthcare market.  In many cases, we have demonstrated an ability to leverage resources to your advantage and raise your market share.

We have partnerships with a number of other cardiology providers to deliver procedures such as coronary stent placement, pacemaker/defibrillator placement, and advanced heart failure/transplant.  Because of hands-on involvement and close working relationship with multiple specialists, we are able to deliver faster care to our patients.
