For those who wonder - cause of death: "My source says he succumbed to complications following his double-bypass surgery." –Scott Mace (2nd link)

Google: The overall risk of death during or within 30 days of double coronary artery bypass surgery (CABG) is very low, generally ranging between 1% and 2%. This translates to a short-term survival rate of 98% to 99%.

For a 74-year-old patient undergoing an isolated double bypass surgery (CABG), the short-term risk of death within 30 days of the procedure generally ranges from 2.5% to 4%. This translates to a short-term survival rate of roughly 96% to 97.5%.

So seems like pretty bad luck on his side.

I remember him back from 90's from reading PC Mag, didn't left that big of an impression on me besides the familiar thumbnail photo and Czech sounding name.
