Add category points for five entered variables from reduced in-hospital and six-month GRACE tables. These subtotals are not complete GRACE risk scores or mortality probabilities.

Enter the five values used by this reduced calculation.
Both results are partial sums of category points—not percentages, absolute risks, or complete GRACE 2.0 outputs. They omit clinical variables required by validated GRACE endpoints. Use an approved clinical tool and professional assessment; do not use these results for triage or treatment decisions.
The GRACE family of models was developed from the Global Registry of Acute Coronary Events to estimate outcomes after acute coronary syndrome. This page accepts age, heart rate, systolic blood pressure, creatinine and Killip class, then adds category points. Because a complete validated GRACE assessment also uses findings such as cardiac arrest at admission, ST-segment deviation and elevated cardiac biomarkers, the two outputs here are labelled reduced point subtotals.
They are not mortality percentages, a complete GRACE 2.0 result, a diagnosis or a treatment recommendation. They should not be used to decide whether someone with chest pain needs care. Chest pressure, shortness of breath, fainting, sweating or pain spreading to the arm, jaw or back warrants emergency assessment according to local guidance.

How to Use This Calculator
Enter measurements obtained in an appropriate acute-care context. Age is in completed years, pulse is beats per minute, and systolic blood pressure is mmHg. Creatinine may be entered in mg/dL or µmol/L; when µmol/L is selected, the page divides by 88.4 before applying its mg/dL bands. Choose Killip class from I through IV based on a clinician’s assessment of heart-failure signs.
Check that the observations refer to the same presentation and are not guesses.
Confirm the creatinine unit printed on the laboratory report. Values such as 1.1 mg/dL and 97 µmol/L are roughly equivalent.
Select the clinically assessed Killip class. Do not infer it from a single symptom without examination.
Calculate to see the reduced in-hospital and six-month point subtotals.
Do not translate either subtotal into a mortality probability. Use an authorized complete model with all required variables for clinical risk estimation.
The page uses category tables rather than continuous coefficients. A small measurement change across a boundary can therefore change the points abruptly even when the patient’s condition has barely changed.
For µmol/L, creatinine in mg/dL = creatinine in µmol/L ÷ 88.4. Each measurement is placed into a predefined band. These sums describe only the five inputs available here. They are not the complete published GRACE risk equations and the page does not supply a calibrated outcome probability.

Clinical meaning and limitation
Age
Completed years
Older age adds more points in the reduced tables; valid adult range on this page is 18–120.
Pulse
Beats per minute
Heart rate at assessment; rhythm and treatment context are not represented.
Systolic BP
mmHg
The upper blood-pressure value; lower bands receive more points.
Creatinine
mg/dL or µmol/L
A renal-function marker converted to mg/dL for banding; unit selection is essential.
Killip class
I, II, III or IV
Clinical heart-failure class, from no signs through shock; it requires professional assessment.

Points, not percent
Reduced five-variable subtotals that omit variables required by full GRACE models.

Worked Example
For age 65, pulse 85 beats/min, systolic pressure 125 mmHg, creatinine 1.0 mg/dL and Killip class I, this page assigns 58 age points, 9 heart-rate points, 34 pressure points, 7 creatinine points and 0 Killip points. The reduced in-hospital subtotal is 108 points. Its alternate six-month age table assigns 36 points at age 65 while the 85 pulse remains 9, producing 86 points with the other bands unchanged.
Entering creatinine as 88.4 µmol/L instead gives 88.4 ÷ 88.4 = 1.0 mg/dL and the same subtotals. These numbers are only a check of this page’s reduced arithmetic. They must not be reported as “108% risk,” “86% risk,” or as outputs from a complete GRACE 2.0 calculation.

Why Use This Calculator?
A larger subtotal means the five entered features accumulated more points under these category tables. It does not show the patient’s absolute probability of death or reinfarction. A complete GRACE tool requires all variables specified by its chosen endpoint and version and converts the model result using validated coefficients or reference tables.
Risk assessment is only one part of acute coronary syndrome care. Electrocardiography, troponin testing, symptoms, timing, comorbidities, contraindications and clinical judgment affect decisions. The model was developed in patients with acute coronary syndromes; applying it to a well person, chronic stable symptoms or an unconfirmed condition does not make the result meaningful. Any professional use should follow current local guidelines and an approved clinical calculator.

Common Mistakes
Reading the displayed points as a percentage or expected number of events.
Calling the reduced subtotal a complete GRACE or GRACE 2.0 risk estimate.
Entering µmol/L as mg/dL, which moves creatinine into an extreme band.
Choosing Killip class without a clinical examination or confusing class number with a symptom count.
Using measurements taken at unrelated times without considering treatment already given.
Assuming a low subtotal makes acute chest symptoms safe to assess at home.
Comparing this subtotal with a complete tool that includes arrest, ECG and biomarker variables.

Frequently Asked Questions
Are the two outputs mortality percentages?
No. They are reduced point subtotals. The page neither completes the validated model nor converts points into an outcome probability.
Why is this called a reduced calculation?
Only five inputs are collected. Full GRACE assessments include additional presentation findings such as cardiac arrest, ST-segment deviation and cardiac biomarkers.
Which creatinine unit should I select?
Select the unit printed beside the laboratory value. The page converts µmol/L to mg/dL using 88.4 µmol/L per mg/dL before assigning its band.
Can I choose Killip class myself?
Killip class reflects clinical signs of heart failure and shock. It should be assessed by a qualified clinician in the context of the examination.
Can this result tell me whether chest pain is an emergency?
No. Do not enter data before seeking help for possible acute coronary symptoms. Emergency triage depends on symptoms and assessment, not this subtotal.
Why might a complete GRACE tool return something different?
It may include all required variables, continuous coefficients, a specified endpoint and calibration. This page uses reduced category sums and therefore is not directly comparable.
Can I compare the in-hospital and six-month numbers as percentages?
No. They come from different point schedules and neither is a percent. A smaller numeric subtotal does not by itself describe a smaller absolute risk across endpoints.
