What móre should we do to preventSudden Cardiac Death ?
Sudden cardiac death
Sudden cardiac death• A leading cause of mortality in the Western world• Estimated incidence of 1-2/1000/year.
Sudden cardiac death 36%Lung Cancer 16%Stroke 16%Breast Cancer 9%Traffic accidents 9%
Sudden cardiac death
• All ages
• Asymptomatic patients
• Often no detectable disease
• SCD 1st symptom in 30%
• Up to 93% lethal arrhythmias
• Normal autopsy
• “Heart Attack – Heart Failure – Heart rupture – Cardiac Arrest”• Underlying diseases:
Sudden cardiac death
10-15% Cardiomyopathies
60-80% Coronary Artery Disease
10-20% Primary Electrical Diseases 1-2% Aortic disease
1-5% Idiopathic Ventricular Fibrillation
Sudden cardiac death
• Primary prevention: AHT, DM, CH, Obesity, Sedentarism, Smoking
• Revascularisation
• Secondary prevention: Controlling Risk factorsHeart failure treatmentICD implantationResynchronisation therapyVT ablation
Prevention of SCD in CAD
VERY LIKELY other high-risk patients out there !
Sudden cardiac deathSCD <45y of age = up to 70% hereditary cause
SCD• Confirm diagnosis
• Identify high-risk relatives
• Pre symptomatic screening
• Prevent transmission to offspring through PGD
SUDS• Molecular autopsy
Sudden cardiac deathGenes have become the key to unlock

Death in BelgiumWhat is a natural cause of death ?
Death in BelgiumHow do you know
And does not affect family ?
What móre should we do to prevent SCD:
1. SCD < 45y = 70% hereditary
2. Investigate family
3. Recognize alarm symptoms
4. Only declare proven natural cause of deathInsist on autopsy as it may save family members
5. Dedicated cardiogenetics clinic
