More Coronary Artery Calcification With City Living

"Green acres is the place for me. Farm livin' is the life for me."

City centre residents who took part in a study were almost twice as likely to suffer from coronary artery calcification (CAC), which can lead to heart disease, than people who lived in less polluted urban and rural areas, according to research published in the May issue of the Journal of Internal Medicine.

Researchers spoke to 1,225 men and women aged 50 and 60 years of age, including 251 (20%) who lived in the centres of major Danish cities.

Despite the fact that none of the participants showed any symptoms of heart disease, 43% of the total had CAC. The study also found that people who lived in city centres were 80% more likely to develop CAC than those living in other areas and that males, older participants, diabetics and smokers also faced higher risks.

I hear singing:

Low blood vitamin D is associated with more coronary artery calcification (CAC). Also, garlic may retard the progression of CAC.

If you must live in the city: Consider a HEPA filter. Also, try to live on a higher floor away from vehicle exhaust soot.

Calcification is now somewhat reversible, if one adheres to a stringent diet and exercise program.
It should be reversible within a decade or two, and then avoidable altogether.
Whether we humans would want to survive into a society dominated by mentally sclerotic codgers, however, is a different problem.

Virulence evolves when you have life forms, such as cities approximate, that need not be healthy in order to transmit their diseases -- for vectors to transport pathogens between them (in this case, the internet can work although clearly cars, trains, jets, etc, can transmit organic pathogens quite nicely).

Since mobility is the ultimate value of the global religion -- a religion, I would contend, born of and dedicated to virulence -- it is clear this is going to play itself out to the destruction of civilization.

The ridicule of "Green Acres" is hilarious.

There's something deeply ironic about fearing that a cure for artery calcification will lead to a society dominated by the "sclerotic".

"than people who lived in less polluted urban and rural areas"

I suspect that "less polluted" is editorializing not supported by any more evidence than any of several other possibilities. For example, perhaps the stress of living in proximity to many people leads, via higher levels of stress hormones, to more calcification.

I missed the part where this is attributed to pollution of urban areas. Could it be attributed to additional stress, noise, ambient light, or even EMF? there are a lot of ways that urban living differs from rural living.

My understanding about coronary calcium was that it did not cause coronary disease but was associated with coronary artery atherosclerosis, and therefore useful to test for by CT.
