Quick answer
Yes, we are accepting new cardiology patients. Fill out the appointment form on this page or call (832) 432-1951 (Northwest Houston), (832) 304-2070 (Tomball) or (832) 645-8992 (Sugar Land). Our team confirms your visit, checks your insurance and tells you whether your plan needs a referral.
Your first visit is about understanding your heart and circulation as a whole. Dr. Khan and our team review your symptoms, your medical and family history, the medicines you take and any earlier test results, then examine you and explain what we found in plain language.
If a test would help, we tell you why, what it involves and where it is done. Many tests, such as an ECG, echocardiogram, stress test or heart monitor, can be scheduled at our offices. Procedures such as cardiac catheterization take place in a hospital setting.
You leave with a clear plan: what is going on, what we recommend next, and when we will see you again. If another doctor referred you, we send them a report so your care stays connected.
