Cardiac Arrest in Young Male
It has been confirmed in many previous studies that sudden cardiac death is often linked with hypertrophic cardiomyopathy in young athletes, but with a divergence of study results.
A recent study observed non-athletes young men and found out that the rate of cardiac arrest among them was higher than those of the young athletes.
‘We performed a meta-analysis to compare the prevalence of sudden cardiac deaths associated with hypertrophic cardiomyopathy versus sudden cardiac deaths associated with structurally normal hearts’.
A time frame of 14 years were used to collect data in this retrospective cohort studies. Various patient registries, and autopsy series were used; examining sudden cardiac death etiology in young individuals not more than 35 year.
The data was divided into 34 studies representing a combined sample of 4,605 subjects.
The overall pooled percentage of sudden cardiac deaths caused by hypertrophic cardiomyopathy was 10.3% while sudden cardiac deaths with structurally normal hearts at death were more common at 26.7% .In non-athlete subjects, the pooled percentage of sudden cardiac deaths associated with structurally normal hearts was 30.7% significantly more common than sudden cardiac death caused by hypertrophic cardiomyopathy .There was no significant difference between summary estimates of hypertrophic cardiomyopathy and structurally normal hearts (p=0.57), except in Europe where structurally normal hearts were more common (p=0.01).
The researchers concluded that ‘hypertrophic cardiomyopathy is not a more common finding at death than structurally normal hearts in young subjects with sudden cardiac death’. The research however did not know the cause of death and advised that more researches are needed to ascertain this. In his words ‘ Increased attention should be directed towards identifying causes of death associated with a structurally normal heart in subjects with sudden cardiac death’
