About Dr. Heart
Eric Jason writes as Dr. Heart (Health Observer) and works on the formula documentation and calculator architecture behind Heart Score Calculator. His role is to turn published health equations into clear tools with visible inputs, source notes and practical limitations.
Dr. Heart reviews how each calculator is explained, including its intended population, accepted units, input limits and result notes. The professional name “Dr. Heart” identifies this editorial work and does not replace advice, diagnosis or treatment from a licensed healthcare professional.

Our Methodology & Data Sources
Dr. Heart documents the published equation behind each tool and checks that the page identifies the formula, required inputs, intended use and known limitations. Primary sources include:
- American Heart Association (AHA) & ACC: For 10-year cardiovascular risk assessment models.
- Academy of Nutrition and Dietetics: Utilizing the Mifflin-St Jeor and Katch-McArdle formulas for precise metabolic (TDEE/BMR) calculations.
- United States Pharmacopeia (USP): Standardized equations for medical dosing and liquid density conversions.
- American College of Sports Medicine (ACSM): Normative data for aerobic fitness and VO2 Max field tests.
Our 3-Step Editorial Process
Before a calculator goes live, the editorial and development process includes three checks:
- Data Sourcing: We extract raw mathematical formulas exclusively from peer-reviewed journals, national health guidelines, and clinical trial publications.
- Algorithm Programming: The published formula is translated into code with named variables, unit controls and defined input limits.
- Output Validation: Common and edge-case inputs are compared with published examples or independently calculated reference results.
