# RISK-E (Olmos 2017) In-Hospital Mortality Score for Active Left-Sided IE Cardiac Surgery

> RISK-E (Olmos 2017) In-Hospital Mortality Score for Active Left-Sided IE Cardiac Surgery is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes the Olmos 2017 RISK-E score for predicted in-hospital mortality after cardiac surgery in active left-sided infective endocarditis, returning a numeric score out of 68.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability risk-e-olmos-2017-in-hospital-mortality-score-for-active-left-sided-bdefc008
```

Example prompt: Calculate the RISK-E score for a 68-year-old patient with active left-sided infective endocarditis going to cardiac surgery — they have periannular complications and cardiogenic shock, no prosthetic valve infection, no Staph aureus or fungi, no acute renal failure, no septic shock, and no thrombocytopenia.

## When to prefer this

Use this endpoint when you need to programmatically compute the Olmos 2017 RISK-E score for in-hospital mortality after cardiac surgery in active left-sided IE, and you have already clinically assigned all seven binary flags and know the patient's age. Prefer this over manual calculation to avoid arithmetic errors in time-sensitive perioperative workflows. Do not use for diagnosis, surgical decision-making, or when echocardiographic interpretation is required — the endpoint performs only arithmetic on caller-supplied inputs.

## Known failure modes

- Missing required query parameter (age or any boolean flag) — likely returns a 400 error
- Age outside integer range 18-120 — may return validation error
- Non-boolean value passed for a flag parameter — schema validation failure
- Network or server error returns 5xx with no score
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Olmos 2017 RISK-E (Risk-Endocarditis) for in-hospital mortality after cardiac surgery in active left-sided IE. Age <=51: 0; 52-63: 9; 64-72: 13; >=73: 14. Flags: prosthetic_infection +6, periannular_complications +5, staphylococcus_aureus_or_fungi +9, acute_renal_failure +5, septic_shock +7, cardiogenic_shock +15, thrombocytopenia +7. Returns score and max_score 68 only. Not a diagnosis or surgery decision. magent does not examine the valve or read echo.

## Output

Returns a JSON object containing the computed RISK-E integer score (sum of age bracket points plus applicable flag points) and the maximum possible score of 68. Does not include diagnosis, surgical recommendation, or mortality percentage.
