Consequences of High Cholesterol

For nearly 60 years, doctors have known about the linkbetween cholesterol and heart disease.

The consequences of high cholesterol can be serious. Most notably, high cholesterol raises the risk of heart disease — there is wide agreement in the medical community on this point. The relationship was first underscored by the pioneering Framingham Heart Study.

Since 1948, that study has monitored 5,209 men and women for the development of coronary heart disease. Data from this and other studies were joined in a report, which showed that the risk for coronary heart disease increases as blood-cholesterol level rises, especially as it rises past 200 mg/dL.


These high levels of blood cholesterol directly contribute to atherosclerosis and heart attack. Low HDL cholesterol and high levels of triglycerides are also factors of the metabolic syndrome, a condition that increases the risk of coronary heart disease.

We’ll start out taking a look at the more high-profile condition. The next page describes the series of events that start with atherosclerosis and can end in a heart attack.
