Study Finds More Evidence
Cigars Not a Safe Smoke
Puffing on one cigar may be enough
to harden the body's main artery for hours afterward, a small
study shows. Researchers say the findings add to evidence that,
far from being a "safe" alternative to cigarettes, cigars increase
the risk of cardiovascular disease.
The study of 12 healthy men who
smoked cigarettes and cigars found that shortly after smoking
a cigar, the men showed evidence of greater stiffness in the aorta,
the main artery carrying blood from the heart to the rest of the
body. The degree of stiffness in large arteries is key in how
well the heart's main pumping chamber can work and blood can flow.
The new findings provide the first
evidence that cigar smoking immediately increases stiffness in
large arteries, according to the study authors, led by Dr. Charalambos
Vlachopoulos of Athens Medical School in Greece. They report the
findings in the American Journal of Hypertension.
Tobacco use in its various forms
has long been known to carry serious health risks. Yet there's
been a popular perception that cigars, which enjoyed a surge in
popularity starting in the 1990s, offer a safer way to smoke.
But research shows that cigar smoking
does boost the risk of heart disease, stroke and several types
of cancer, including lung and oral cancers.
In the new study, the researchers
used a measure called pulse wave velocity to gauge aortic stiffness
in 12 young, male smokers for two hours after they smoked a cigar,
and after they puffed on an unlit cigar.
The men's aortic stiffness increased
"promptly" after they smoked the cigar and stayed elevated for
the two-hour study period, according to Vlachopoulos and his colleagues.
It's unclear what these immediate
effects mean for the long term, the researchers point out. But,
they add, hours of daily arterial hardening over time would "logically"
put a burden on heart and artery function.
This study, they conclude, "provides
further evidence that cigar smoking increases cardiovascular risk,
and fights the promoted perception that cigars are innocuous alternatives
to cigarettes."
