Post-Cardiac Rehabilitation Risk Reduction Score Calculator

Clinical calculation support · Verify results before clinical use

Patient factors and rehabilitation participation

Enter the patient characteristics below to calculate the arithmetic score retained from the supplied template.

0 Score

Enter an age from 18 to 120 years.

0 to +2 points
Gender

The supplied algorithm assigns one point for male sex.

Current smoking status
Diabetes mellitus
Cardiac rehabilitation attendance

“Yes” means the patient attended a cardiac rehabilitation program.

-2Arithmetic score
Calculated output

Not a validated risk estimate

This number is the arithmetic output of the supplied point rules. It does not estimate an individual's absolute risk, mortality, or the benefit attributable to cardiac rehabilitation.

Clinical validity warning The point weights and the subtraction for rehabilitation attendance have not been verified as a validated prognostic model. Do not use this score to guide treatment, determine prognosis, or communicate a percentage risk reduction. Cardiac rehabilitation benefits are supported by clinical evidence, but those benefits cannot be calculated from this score.

About this calculator

This page preserves the arithmetic rules in the supplied PHP template for transparency, while explicitly identifying the score as unvalidated. It is not a published or externally validated “Post-Cardiac Rehabilitation Risk Reduction Score.”

The possible arithmetic range is −3 to 7. No validated score categories, calibration, discrimination, or clinical cutoffs are available for these weights.

Clinical context

Cardiac rehabilitation is an evidence-based component of secondary prevention. Observational studies report associations between participation and improved outcomes, but the magnitude of benefit varies by population, program exposure, adherence, and study design. Such evidence does not validate the custom point weights used here.
