Beyond stars and reviews — what 48,000 verified patient reviews tell us about how to actually pick a cardiologist.

The headline rating is almost useless. The reviews underneath it are where the signal lives.

The metrics that matter

When we cluster reviews by outcome satisfaction, three factors dominate: time spent in consultation, clarity of diagnosis explanation, and willingness to recommend lifestyle-first interventions before procedures.

Volume vs. outcomes

High-volume cardiologists are not always better. Above ~40 procedures per month, patient-reported satisfaction starts to decline — likely a function of consultation time.

The best predictor of patient satisfaction is not the doctor reputation. It is the average consultation length.

Ask before you book: "How long is a typical first consultation?" Anything under 15 minutes is a yellow flag for a complex specialty like cardiology.
