Cycling puts more strain on your heart than most other sports, apart from rowing - especially with the sudden and vastly differing changes in pace/heart rate you get in road racing. This can lead to problems in those people who already are pre-disposed, either due to a heart defect from birth, or a slowly developing condition like high blood pressure. Congenital heart defects can be screened for, if you have a family history of these problems - see your GP. Blood pressure can easily be checked by a nurse, doctor, or other health professional.
Everyone gets a bit blase about training/racing when we are under the weather or off form. Also more and more people are getting into mass participation sports, weather it's bike events, running races or triathlons/adventure races, so with that there'll be a greater number of casualties.
In alot of cases it boils down to taking the precautions already mentioned, and getting blood pressure and cholesterol levels (predictors of cardiac accidents) checked regularly - it's not just overweight heavy smokers and drinkers that need to get these checked.
