Expatriates with international health insurance may be interested to know that athletic people are more likely to die of sudden cardiac death than was previously thought.
Dr Jonathan Drezner, vice-president of the American Medical Society of Sports Medicine, said in a podcast from the British Journal of Sports Medicine that recent research has shown professionals were underestimating its prevalence.
These studies had often utilised media reports to correlate causes of death, but this means they "missed out on almost half the cases", he declared.
Usual estimates of one athlete in every 200,000 are incorrect, Mr Drezner asserted, citing research he, his colleague Dr Kim Harmon and others at the University of Washington were involved in.
They looked through five years of National Collegiate Athletic Association members and discovered "the average incidence in that population is about one in 45,000".
Most occurrences of this form of heart failure are due to cardiac arrhythmias and death typically happens a very short time after initial symptoms are experienced.
