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.
