Key findings

What ClinicalTrials.gov does not surface for Heart Diseases on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. Heart Diseases is recruiting below its size-band peers.

    26 of 86 indexed trials (30.2%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Heart Diseases trials is spread across many organizations.

    National Heart, Lung, and Blood Institute (NHLBI) accounts for 7 of 86 trials (8.1%). 64 distinct sponsors appear on at least one study for this condition label.

  3. Typical Heart Diseases enrolment sits around 349 participants.

    Median target enrolment is 349 among the 86 trials that report a genuine target (sentinel values excluded). 16 of those (18.6%) plan for fewer than 100 participants.

  4. Heart Diseases splits between interventional and observational designs.

    54 interventional and 32 observational studies make up this index (62.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
