I don't think they ever confirm he has the heart condition, just when they screen him as an infant there is "~99% chance" he has it. Part of the plot is that the main character and others like him are never given a chance at anything in life because genetics have become viewed as destiny. They have futuristic advanced medical technology that probably could give everyone a good, meaningful life. He lives at the best time in history to survive a heart condition and yet he can't even get into daycare because the insurance won't cover him. The society in Gattaca has used their advanced technology to imprison themselves and eliminate social mobility rather than expand it.
