Intro to our Studies

Sudden death is defined as natural (non-traumatic) death that occurs within an hour of the onset of acute symptoms or during sleep. Although sudden non-traumatic deaths are frequently attributed to cardiac disease, autopsy studies in unselected subjects suggest that about one third of sudden deaths have non-cardiac causes (eg: intracranial bleed, pulmonary embolism, acute asthma). The sub-division of sudden death based on underlying cardiac causes is defined as sudden cardiac death or sudden cardiac arrest (SCA). There may or may not be a pre-existing diagnosis of heart disease, but the time and mode of death are unexpected.

The reported incidence rates of SCA are variable. This variability is related to the study population and the inherent vagaries of classifying the mode and time of death, particularly in the absence of post-mortem studies. The incidence of SCA increases from less than 10 per 100,000 person-years in young healthy individuals (age < 35 years) to over 50 per 10,000 person-years in patients with structural heart disease, and the incidence is greater in males compared to females.

Coronary artery disease (CAD) and the associated complications account for the majority of SCA, and arrhythmic syndromes are often regarded the prima facie cause of SCA in the absence of significant CAD. Avoiding the pitfalls of misdiagnosis, the potential implications for the patient and the family demands a comprehensive and systematic approach for the identification of reversible or attributable causes in the SCA survivor. This review will outline a diagnostic approach to the SCA survivor.
