Deep dives
Atherosclerosis and Heart Disease
Atherosclerosis is a condition where plaque builds up in the coronary arteries, ultimately leading to heart disease, which is the leading cause of death globally. The discussion emphasizes that while nearly everyone will develop atherosclerosis at some point, the goal is to do so as late in life as possible to avoid heart attacks, which are the true killers. Recent statistics indicate that cardiovascular disease accounts for approximately 20 million deaths annually, outperforming cancer as a cause of mortality. However, there has been a noticeable decline in early heart disease deaths over the past 50 years, largely attributed to reduced smoking rates, although disparities exist across socioeconomic classes.
