About this tool

Heart Disease Risk Calculator

Educational estimates of coronary artery disease, stroke, atrial fibrillation and lipid-related risk from common factors. Not a diagnosis.

Pick the risk, enter your numbers and see an educational estimate with what moves it. Talk to a doctor about your result. This page brings together 4 separate heart disease risk calculator pages (Atrial fibrillation (AFib), Coronary artery disease, Lipid, Stroke) so you can compare them without hunting for the right one.

How to use Heart Disease Risk Calculator

  1. 1

    Open Heart Disease Risk Calculator on AltFTool — it loads instantly in your browser.

  2. 2

    Choose your risk at the top: Atrial fibrillation (AFib), Coronary artery disease, Lipid, Stroke. On a phone it is a drop-down list.

  3. 3

    Fill in the heart disease risk calculator for that risk; each of the 4 options keeps its own rules, data and defaults.

  4. 4

    Read the result, then switch risk to compare. The page link keeps your risk (?v=atrial-fibrillation), so you can bookmark or share it.

Why use Heart Disease Risk Calculator

  • All 4 in one place

    Atrial fibrillation (AFib), Coronary artery disease, Lipid and the rest sit behind one picker, so switching risk takes a tap instead of a new search.

  • Built for each option

    Every risk keeps its own rules, numbers and defaults rather than one generic template.

  • Shareable view

    The link remembers the risk you picked, so a bookmark or a shared link opens straight on it.

Common use cases

  • You are 68 with treated hypertension and a BMI over 30, and want a structured sense of how those stack up before a routine cardiology appointment.
  • Your doctor mentioned your 10-year risk came out around 9 percent and suggested a statin, and you want to understand which of your inputs — the smoking, the blood pressure or the HDL — is driving that number.
  • Working out your cholesterol ratio from a printout that lists only the raw values, without hand-dividing total by HDL
  • You have just been told you have atrial fibrillation and want to understand why your cardiologist raised blood thinners before your follow-up appointment.

Frequently asked questions

Which risk options does this tool cover?

4: Atrial fibrillation (AFib), Coronary artery disease, Lipid, Stroke. Pick one at the top of the tool; the page link updates (for example ?v=atrial-fibrillation) so you can bookmark or share that exact view.

What score means high risk of atrial fibrillation?

In this simplified 14-point scheme, 0-2 is Low, 3-4 Moderate, 5-7 High and 8-14 Very High, with indicative annual AF incidence of under 1%, 1-3%, 3-5% and over 5% respectively. These are broad bands from population data, not a prediction for any individual.

What counts as high 10-year ASCVD risk?

Under the ACC/AHA categories, below 5 percent is low, 5 to 7.4 percent is borderline, 7.5 to 19.9 percent is intermediate, and 20 percent or more is high. The 7.5 percent mark is the threshold at which guidelines begin discussing statin therapy, alongside risk-enhancing factors — that decision belongs with your doctor.

What is a good cholesterol ratio?

A TC/HDL ratio below 5.0 is generally described as desirable and an LDL/HDL ratio below 3.0 likewise; lower is better in both cases. The gauges here turn amber above 4 and red above 5, which is where the score starts adding points.

What CHA₂DS₂-VASc score means I need a blood thinner?

Guidelines generally recommend oral anticoagulation from a score of 2 or more, treat 1 as an individual risk-benefit discussion, and consider no anticoagulation at 0. The final decision belongs to your doctor, who will weigh bleeding risk, kidney function and your own preferences.
