For many years the role of elevated cholesterol in cardiac disease has been
debated but never adequately resolved. Several years, research suggested
that a bacterium, chlamydia pneumoniae, possibly may be implicated in heart
disease. Now, workers are investigating the possibility that other bacteria
may also be involved in the process of cardiac disease.
I first read about this theory in 1997 soon after I had a near fatal heart
attack and quadruple bypass surgery and I raised the subject with my
cardiologist, who confirmed that he had also been studying the same research.
As a result, he suggested that I took a short dose of a specific antibiotic
called Azithromycin.
One of the sources which discussed this discovery was the Canada News, which
stated:
"Ours is the first compelling experimental evidence in the world to show how
a bacterial infection in the genital tract or lungs can lead to heart
disease," Dr Penninger said of the study that his team published in the
scientific journal 'Science' (February 26, 1999).
Penninger and his research team found that the chlamydia bacterium resembles
the heart protein that makes the heart beat, but the body's immune system
can't tell the two apart. As a result, the immune system, which uses white
blood cells to kill off infectious diseases foreign to the body, is tricked
into launching twin attacks to destroy the invading bugs. It first attacks
the offending bacteria and then the heart protein. "

Now, Penninger and co-workers have reported in 'Nature Medicine' (Aug 2000)
that bacteria, viruses and other microbes are all components of the protein
bit that is common to heart muscle and the chlamydia bacterium (Science News
Aug 2000, Vol 18).
In other words, microbes may play a central role in heart disease. Who
knows, within a few years elevated cholesterol and sedentary lifestyle may be
replaced by a dominant theory that heart disease may be "caught" like a
common cold and that all of the recommendations!
