Smoking, Even for a Short Time, Significantly Increases a Woman's Risk for Peripheral Artery Disease
PHILADELPHIA - (BUSINESS WIRE) - A prospective study of initially healthy women aged 45 and over found
that smoking is a potent risk factor for symptomatic peripheral artery
disease, or PAD. PAD is a serious, often debilitating disorder, caused
by narrowing of the arteries in the lower extremities. Symptoms of PAD
include pain in the legs with normal activity and a feeling of tiredness
in the leg muscles.
Researchers followed 38,825 women for an average of 12.7 years to
determine if smoking increased a woman's risk for PAD and if smoking
cessation reduced that risk. The women were questioned about their
smoking history and if they currently smoked cigarettes. If so, they
were asked to disclose how many they smoked per day. During the course
of the study, patients periodically filled out questionnaires about
their health and smoking habits. Surveys were given twice during the
first year and then once per year for the remainder of the study and
follow-up period. Participants were asked to report any symptoms of PAD.
The researchers found that smoking increased a woman's risk for PAD
10-fold. Smoking cessation reduced the risk, but even after abstaining
from cigarettes for 20 years, the risk did not lower to that of a woman
who had never smoked.
"This study showed that-as has been previously shown for heart attacks
and for lung cancer-that smoking is actually very harmful for the
development PAD," said Eruna Pradhan, Assistant Professor of Medicine at
Harvard Medical School and an author of the study. "This is significant
because PAD is a disease that not only causes a lot of pain and
discomfort with usual, daily activities but it also increases the risk
of heart attack."
