Treatment of Alcohol-Induced Cardiomyopathy in Dilated Cardiomyopathy with Additional Risk Factors

This protocol addresses alcohol-induced cardiomyopathy occurring in the context of dilated cardiomyopathy (DCM), where no genotype associated with high sudden cardiac death risk has been identified, left ventricular ejection fraction remains above 35%, and specific additional risk factors are present.

Clinical Scenario

The patient presents with dilated cardiomyopathy without a genotype linked to elevated sudden cardiac death risk, and with a left ventricular ejection fraction greater than 35%. At least one of the following additional risk factors is present:

  • Syncope (unexplained loss of consciousness)
  • Late gadolinium enhancement detected on cardiac magnetic resonance (CMR) imaging

Treatment Approach

In this specific clinical setting, guidelines support considering an implantable device-based intervention targeting arrhythmic risk — though the full selection criteria, sequencing, and individualised considerations go beyond what can be summarised here.

References

An ICD may be considered in patients with DCM without a genotype associated with high SCD risk and LVEF >35% in the presence of additional risk factors.

Additional risk factors include syncope, LGE presence on CMR.
