EMERGENCY NOTICE: If you or a loved one are experiencing acute crushing chest pressure, pain radiating to the neck/jaw/left arm, sudden severe breathlessness, or dizziness during chemotherapy or immunotherapy, please call your local emergency services (911 in the US/Canada, 999 in the UK, 112 in the EU) or proceed immediately to the nearest Emergency Room.

1. Informational & Supportive Purpose Only

The content provided on CardioOncoGuides (accessible at cardio.oncoguides.org and across the OncoGuides Network) is published solely for educational, supportive, and informational purposes. The information, interactive risk calculators, cardioprotective medication profiles, echocardiography surveillance guidelines, and non-profit grant directories are designed to support, not replace, the relationship that exists between a patient and their oncologist, cardiologist, or healthcare team.

2. No Doctor-Patient Relationship

Use of this website, including calculation of baseline cardiotoxicity risk scores or logging of echocardiogram numbers in the hospital health vault, does not establish a doctor-patient relationship, clinical consultation, or prescription order. You should never delay seeking medical advice, disregard professional medical counsel, or discontinue any oncology or cardiovascular medications based on information found on this website.

3. Diagnostic and Treatment Variability

Cardiovascular responses to chemotherapy (e.g., Doxorubicin, Trastuzumab, 5-FU) and immunotherapy (e.g., Pembrolizumab, Nivolumab) vary significantly based on individualized genetic factors, cumulative dosages, and pre-existing cardiovascular comorbidities. All diagnostic and therapeutic decisions must be made in consultation with qualified clinicians.

4. Financial Aid & Non-Profit Directory Accuracy

While CardioOncoGuides continuously audits and verifies the non-profit copay foundations and patient assistance funds listed in our directory, fund availability, income eligibility criteria, and maximum grant caps change frequently based on foundation funding allocations. We do not guarantee grant approval or financial disbursement.
