Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $65,310 of the $66,763 with a category attached, or 97.8%. AstraZeneca accounts for 62.8% of it on its own, with 4 other manufacturers making up the rest. 2025 is the largest year on record at $18,000, more than ten times the $1,047 reported in 2019. Among cardiovascular disease clinicians in CT with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

Who reported the general payments

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
