Conclusion

In this comprehensive, nationwide study of SCD due to HCM, 87% (33/38) of cases had one or more abnormality prior to death, including cardiac symptoms, a positive family history, known cardiac disease or ECG abnormalities.
They sought medical care prior death, to a larger extent than controls.

These findings suggest that cardiac screening should be expanded beyond competitive athletes to aid SCD prevention in the young population with HCM.


Trends Show Overall Decrease in HCM-Related SCD But Disparities Remain (2022)

Nuvarande trend för hypertrofisk kardiomyopati-relaterad plötslig hjärtdöd (SCD) har minskat avsevärt under de senaste 60 åren.
Men hög förekomst hittades hos unga patienter med HCM, och det finns geografiska skillnader i att få SCD-förebyggande behandling, enligt en studie publicerad
28 september 2022 i JACC: Clinical Electrophysiology.


Risk stratification of sudden cardiac death: a review 

(Augusti 2023)

Abstract
Sudden cardiac death (SCD) is responsible for several millions of deaths every year and remains a major health problem.
To reduce this burden, diagnosing and identification of high-risk individuals and disease-specific risk stratification are essential.

Treatment strategies include treatment of the underlying disease with lifestyle advice and drugs and decisions to implant a primary prevention implantable cardioverter-defibrillator (ICD) and perform ablation of the ventricles and novel treatment modalities such as left cardiac sympathetic denervation in rare specific primary electric diseases such as long QT syndrome and catecholaminergic polymorphic ventricular tachycardia.

This review summarizes the current knowledge on SCD risk according to underlying heart disease and discusses the future of SCD prevention.
