Decode your numbers, calmly.
Free, evidence-based tools for the moment your lab results come in. No login. No medical advice. Just the calm middle.
Lipid Panel Translator
Paste your full lipid panel (LDL, HDL, Trigs, ApoB, Lp(a)). Get a plain-English readout per marker, contextualized to your age and family history.
Should I Get a CAC Scan?
Six questions. Honest recommendation on whether to push your doctor for a coronary calcium scan — plus a script to use in the appointment.
Perimenopause Cholesterol Estimator
Did your LDL jump in your 40s? See where your number sits on the typical pre-peri-post menopause trajectory — and whether the rise is normal or worth flagging.
ApoB / LDL Discordance Checker
When particle count and cholesterol mass disagree, the particle count usually wins. Check whether your numbers are concordant — or hiding risk.
Why we built these
The moment you get a lab result back is rarely the moment your doctor is available to walk through it with you. Most people end up alone with a portal screen full of numbers, a search bar, and a rising heart rate. Search results are dominated by either AHA-orthodoxy boilerplate that dismisses the rise, or carnivore-bro YouTube takes that tell you cholesterol doesn't matter. Neither is useful. Hey Heart's tools are built for the calm middle — evidence-based, honest about what the markers do and don't predict, and specific enough to be actionable.
Every tool runs entirely in your browser. Nothing you enter is transmitted, logged, or stored unless you specifically opt to email yourself a printable PDF. We don't sell data, we don't share with advertisers, and the calculation itself is open enough that any cardiologist could audit it against the source guidelines on the methodology page.
Which tool to start with
If you just got a lab result back and you're trying to make sense of the whole panel: the Lipid Panel Translator is the right starting point. It reads every standard marker plus ApoB, Lp(a), and non-HDL, and puts each one in context against the AHA's 2026 targets and your specific risk profile. If you're a woman in perimenopause or postmenopause and your numbers jumped, start there to see whether the rise is typical for your stage.
If you're past the "what does this mean" question and onto the "what should I do" question: the CAC scan decision tool walks through whether a coronary calcium scan would actually change your plan, with a doctor-conversation script you can use in your appointment. If your LDL looks fine but you suspect your particle count tells a different story, the discordance checker is the focused version of that question.
What these tools deliberately don't do
They don't recommend specific medications, dosages, or therapy changes. They don't calculate a precise 10-year ASCVD risk score (use the ACC/AHA risk calculator and your clinician for that). They don't diagnose familial hypercholesterolemia, metabolic syndrome, or any other condition. And they don't replace a clinician who knows your full history — they're built to make that conversation more productive, not to substitute for it.
If you're looking for the deeper backstory on a specific marker, our blog has explainers on ApoB vs LDL, why an Lp(a) test is worth pushing for, how to interpret an LDL of 160, and what to do tonight if you just got flagged.
These tools are for education, not medical advice. Interpretation rules cite the 2026 AHA/ACC dyslipidemia guidelines, the 2021 ESC and CCS lipid guidelines, and peer-reviewed literature linked on the methodology page. Always discuss results with a clinician who knows your full history.
