Cardiovascular disease research — NIH Funding Overview

Reviewed by Dr. Meng ZhaoLast reviewed June 9, 2026Data refreshed September 5, 2026Editorial standards

Cardiovascular disease (CVD) research at NIH is led by NHLBI, with contributions from NIA, NIDDK, and NHGRI on metabolic and genetic risk. Active areas include heart failure with preserved ejection fraction (HFpEF), atherosclerosis biology, hypertension, arrhythmia genetics, and population-level prevention.

Why this matters now

CVD remains the leading cause of death in the U.S., and NIH portfolios have expanded with the GLP-1 era to include cardiometabolic intersections. Implementation and equity science has grown alongside the BLOCK and STRIVE-related programs.

How NIH funds this area

NHLBI mechanisms include R01, U01, P01, K-series, and large clinical trial cooperative agreements (U10, U24). Data below covers all NIH awards mentioning cardiovascular in title, abstract, or terms.

How to use this funding brief

Use this page to narrow cardiovascular funding into heart failure, atherosclerosis, hypertension, arrhythmia, prevention, or implementation science. Broad totals are useful for scale, but institute fit becomes clearer only after choosing the clinical or biological decision your project addresses.

Search tactics

  • Search "heart failure", "atherosclerosis", "hypertension", or "arrhythmia" for narrower scope.
  • For population science, search "cardiovascular disparities" or "CVD prevention".
  • NHLBI Comprehensive Sickle Cell Centers and population studies are large-scale anchors.

What the data shows

$1.0B$2.0B$3.0B$4.1BFY21FY22FY23FY24FY25FY26*
Total NIH award dollars mentioning CVD per fiscal year, from the NIH RePORTER snapshot refreshed September 5, 2026. *The most recent fiscal year is still accumulating awards.
  • Funding peaked in FY2023 at $4.1B. The FY2025 total of $3.6B is +3% versus FY2021.
  • The number of awards fell about 7% in FY2025 even as total dollars grew — funding is concentrating in fewer, larger awards.
  • About 78% of FY2026 dollars so far are non-Type-1 award actions, including competing renewals, supplements, non-competing continuations, and institutional changes. This is a descriptive record mix, not a measure of renewal activity alone.
  • The average FY2025 award was $622K, and R01 was the most common mechanism in the recent window.

Editorial read

Cardiovascular funding is large but flat: FY2025 is essentially unchanged from FY2021 and below the FY2023 peak, across one of the biggest award bases we track (more than 33,000 awards in five years). Flat nominal funding in a portfolio this size usually means intensifying competition at the margins — the momentum lives in subfields like heart failure, arrhythmia, and implementation science, so narrow the question before judging the market.

Counts and total funding per fiscal year from NIH RePORTER. Recent fiscal years may understate final totals because of reporting lag.

    ABSTRACT Existing treatments for acute kidney injury (AKI) are limited to supportive care, and there are no current therapies that can modify the disease course or prevent progression to chronic kidney disease (CKD) and ultimately end-stage renal disease (ESRD). While AKI has multiple causes, cardiac surgery-associated AKI (CSA-AKI) is a major etiology.…
