Cardiology

San Antonio

177 businesses listed, showing 1–40. How we order them.

San Antonio's cardiology category lists 177 entries, but the count alone doesn't tell you who actually answers the phone. Of those, 174 have a phone number on file and 150 link out to a website, so most entries carry a real way to reach someone before you drive out to zip code 78229, which holds 59 of the listings, more than any other area in the city.

None of these listings are marked verified, so treat the directory as raw data rather than a curated shortlist. Paid placements would carry a Sponsored tag if any ran here, and right now this category has zero, meaning every entry sits in the same unpaid, unranked order. If you run one of these cardiology practices and the phone number bounces or the website link is dead, you can claim the listing and update the details yourself, so a patient searching by zip code in San Antonio doesn't hit a dead end. Call two or three offices near your zip before assuming coverage, since listing counts vary widely by area, from 59 in 78229 down to single digits in zips like 78201 and 78215.
