ESC HCM Risk Score:
| From: | To: |
The ESC (European Society of Cardiology) HCM (Hypertrophic Cardiomyopathy) Risk Score is a validated tool to estimate the risk of sudden cardiac death in patients with hypertrophic cardiomyopathy. It helps guide decisions about implantable cardioverter-defibrillator (ICD) implantation.
The calculator uses the ESC HCM risk equation:
Where:
Explanation: The equation incorporates multiple clinical parameters to provide a personalized risk assessment for sudden cardiac death in HCM patients.
Details: Accurate risk stratification is crucial for identifying HCM patients who would benefit from preventive measures such as ICD implantation to reduce the risk of sudden cardiac death.
Tips: Enter age in years, maximum wall thickness in mm. Additional clinical parameters may be required for a complete assessment according to ESC guidelines.
Q1: Who should use this risk calculator?
A: This calculator is intended for healthcare professionals to assess sudden cardiac death risk in patients with confirmed hypertrophic cardiomyopathy.
Q2: What is considered a high-risk score?
A: According to ESC guidelines, a 5-year risk of sudden cardiac death ≥6% is generally considered high risk and may indicate need for ICD implantation.
Q3: What other factors are considered in the full ESC risk assessment?
A: The complete assessment includes family history of sudden cardiac death, unexplained syncope, non-sustained ventricular tachycardia, left ventricular outflow tract gradient, and left atrial size.
Q4: How often should risk be reassessed?
A: Risk should be reassessed periodically, typically every 1-2 years, or when new clinical events occur or there are changes in clinical status.
Q5: Are there limitations to this risk score?
A: The risk score should be used as part of a comprehensive clinical assessment and may have limitations in certain patient subgroups or those with specific comorbidities.
