Why the study?
Sudden death in a family causes severe anxiety, and assessing the cause of death can determine risk for relatives, but standard autopsy often fails to reveal arrhythmic causes.
Genetic assessment and clinical evaluation are crucial for risk stratifying family members after a sudden cardiac death to guide appropriate preventive interventions.
May inform family screening after sudden cardiac death; hypothesis-generating and requires validation in larger cohorts.
Sudden death in a family is associated with serious anxiety among family members. Assessing the cause of death may help determine the risk for other family members, thus alleviating some anxiety. In some cases, the cause of death may be evident on autopsy; however, in cases of arrhythmias, standard autopsy will not reveal the cause of death. Evaluation of the circumstances of death, medical history of the deceased, and results of genetic testing may reveal a diagnosis. Once a diagnosis is made, relatives should receive genetic testing and clinical assessment to stratify their risk. Depending on their risk, various interventions are available, including medication, defibrillators, and lifestyle modifications.
