Silent MI linked to sudden cardiac death risk
More than 40% of sudden cardiac death cases have old myocardial scarring, shows study
A substantial proportion of people experiencing sudden cardiac death have no history of coronary artery disease (CAD) but many show signs of a previously undetected MI at autopsy, according to Finnish and US researchers.
To examine the prevalence of silent MI in those with sudden cardiac death and autopsy-defined CAD, the team analysed data on more than 5800 people who had experienced sudden cardiac death. Most (78.8%) were men.
