Clinical Utility and Validation of the Krakow DCM Risk Score-A Prognostic Model Dedicated to Dilated Cardiomyopathy

Area of Science:

• Cardiology
• Heart Failure Research
• Clinical Prognostics

Background:

• Dilated cardiomyopathy (DCM) is a leading cause of heart failure with high mortality.
• Accurate prognosis is crucial for managing DCM but validated tools are lacking.
• Existing risk stratification methods are insufficient for the DCM population.

Purpose of the Study:

• To validate the predictive accuracy of the Krakow DCM Risk Score.
• To assess the score's ability to identify high-risk patients for targeted interventions.
• To establish a reliable tool for DCM prognosis in clinical practice.

Main Methods:

• A validation cohort of 329 DCM patients was analyzed (2009-2020).
• Individual mortality risk was calculated using the Krakow DCM Risk Score.
• Patient outcomes were followed for a mean of 42 months.

Main Results:

• The Krakow DCM Risk Score demonstrated good discrimination for overall mortality risk (AUC 0.704-0.765).
• A 2-year mortality risk exceeding 6% significantly identified high-risk patients (observed mortality 42.6% vs. 8.3%).
• The score showed good predictive accuracy in the validation cohort.

Conclusions:

• The Krakow DCM Risk Score is a validated tool with good predictive accuracy for DCM mortality.
• The 2-year mortality risk threshold (>6%) effectively discriminates high-risk individuals.
• This score can be readily applied in routine clinical practice for DCM patient management.
