It’s unclear what condition he had. Initial reports were some ischemic heart disease which really doesn’t make any sense for a world class athlete. Hypertrophic cardiomyopathy would make way more sense for sudden cardiac death in an athlete. That disease is almost always genetic, so he probably had it his whole life.
Either that or the doping allegations were true and that led to the inflammation of his heart and a different type of cardiomyopathy which could have also been the cause of death.
