HFA-ICOS Baseline Cardio-Oncology Risk Assessment for Multi-Targeted Kinase Inhibitors for CML

Baseline cardiotoxicity risk stratification before a BCR-ABL tyrosine kinase inhibitor for CML.

HFA-ICOS Baseline Cardio-Oncology Risk Assessment for Multi-Targeted Kinase Inhibitors for CML
Arterial vascular disease
Ischaemic heart disease, prior PCI/CABG, stable angina, TIA, stroke, or peripheral arterial disease.
Arterial thrombosis while on a prior TKI
Heart failure or left ventricular systolic dysfunction
Prior BCR-ABL TKI-mediated LV systolic dysfunction
Abnormal ankle-brachial pressure index
Pulmonary arterial hypertension
Baseline LVEF <50%
QTc ≥480 ms
10-year cardiovascular disease risk >20%
Age ≥75 years
Current smoker or significant smoking history
Venous thromboembolism (DVT or PE)
Arrhythmia
QTc 450-480 ms (men) or 460-480 ms (women)
Hypertension

Diabetes mellitus
Hyperlipidaemia
Age ≥60 years
Chronic kidney disease
Family history of thrombophilia
Obesity (BMI >30 kg/m²)
ResultLow risk

No or only a single medium-risk (1-point) factor is present. Routine baseline assessment is sufficient.

Medium-risk points
0
Overall risk category
Low risk

When to use

  • Baseline cardiovascular risk stratification before starting BCR-ABL tyrosine kinase inhibitor therapy in patients with cancer.
  • Determining how intensively to monitor cardiac function during treatment.

Formula

Overall risk = Very high if any very-high-risk criterion is present; otherwise High if any high-risk criterion is present OR medium-risk points total ≥5; otherwise Moderate if medium-risk points total 2-4; otherwise Low (0 or 1 medium-risk point). Medium-risk items are weighted 1 or 2 points as specified.

Pearls and pitfalls

  • Any single very-high-risk criterion overrides the point total and classifies the patient as very high risk.
  • Risk category is intended to guide referral to cardio-oncology and the frequency of on-treatment cardiac imaging/biomarker surveillance, not to withhold effective cancer therapy.
