The Role Of Preventive Cardiology And Coronary Atherosclerosis In Cardiology Today

Atherosclerosis begins decades before it causes symptoms, which is the single most useful thing to know about it. Fatty streaks appear in arteries in early adult life and build slowly, so risk accumulates over a lifetime rather than arriving at retirement. Research measuring this process in healthy people has shown how early it starts and how much of it is modifiable. The practical consequence is that prevention started in middle age is late but useful, and prevention maintained from early adulthood is far more powerful.
