HFA-ICOS Baseline Risk before Anthracycline Chemotherapy calculator
Enter the published formula inputs below to calculate and interpret this score.
Clinical inputs
Allowed range: 18–110 years
Age 80 years or older is high risk. Age 65 through 79 is a medium-2 factor. Under 65, age adds no points.
Allowed range: 5–80 %
Ejection fraction under 50% is high risk. From 50% through 54% is a medium-2 factor.
Allowed range: 60–260 mmHg
Systolic pressure above 140 mmHg or diastolic pressure above 90 mmHg counts as hypertension. Values of 140 and 90 do not.
Allowed range: 30–160 mmHg
Systolic pressure above 140 mmHg or diastolic pressure above 90 mmHg counts as hypertension. Values of 140 and 90 do not.
Allowed range: 4–20 %
Hemoglobin A1c above 7.0% counts as diabetes. A value of 7.0% does not.
Allowed range: 1–200 mL/min/1.73 m²
Estimated glomerular filtration rate under 60 is a medium-1 factor. A value of 60 is not.
Allowed range: 10–80 kg/m²
Body mass index above 30 kg/m² is a medium-1 factor. A value of 30 is not.

Lyon AR et al. Baseline cardiovascular risk assessment in cancer patients scheduled to receive cardiotoxic cancer therapies: a position statement from the HFA Cardio-Oncology Study Group in collaboration with the International Cardio-Oncology Society. Eur J Heart Fail. DOI: 10.1002/ejhf.1920. PMID: 32463967. Table 2, anthracycline proforma. Very high: heart failure or cardiomyopathy. High: severe valvular disease, myocardial infarction or coronary revascularisation, stable angina, LVEF under 50%, age 80 or older, previous anthracycline, prior radiotherapy to the left chest or mediastinum. Medium 2: LVEF 50–54%, age 65–79. Medium 1: troponin above the local upper limit, BNP or NT-proBNP above the local upper limit, hypertension (systolic pressure above 140 mmHg or diastolic above 90 mmHg or on treatment), diabetes (HbA1c above 7.0% or on treatment), eGFR under 60, previous non-anthracycline chemotherapy, current smoking or a significant smoking history, BMI above 30. Low risk is no risk factor or a single medium-1 factor. Medium risk is medium factors that add to 2 to 4 points. High risk is any high-risk factor or medium factors that add to 5 or more points. Very high risk is any very high-risk factor. Medium 1 counts 1 point and medium 2 counts 2 points. A single age and a single ejection fraction contribute only the highest matching row. (2020)
