Los Angeles carries 206 cardiology listings on this page, more than most people want to scroll through when they just need a heart doctor nearby. Narrowing starts with location: the 90048 zip alone holds 25 of these practices, so if you're in that stretch you have a dense cluster to pick from before widening the search. Everywhere else the count thins out fast, so knowing your zip first beats reading the full list top to bottom.

Of the 206 practices, 162 list a website you can check before calling, which still leaves a chunk with phone number only, so call two or three if a site isn't listed. Paid placements on this page get a Sponsored tag so you can tell them apart from the rest, and none are active in Los Angeles cardiology right now, meaning what you see is plain directory order. If you run one of these practices and the phone number or site link looks wrong, you can claim the listing yourself and fix it, which matters most for patients trying to reach someone in a crowded zip like 90048.
