Two out of three Canadians not aware of peripheral arterial disease
If a good night’s sleep helps the brain and body perform better, it’s a good guess that sleep problems can cause more than just fatigue. Numerous studies have shown a connection between sleep disorders and medical conditions such as cardiovascular disease, cerebrovascular disease, and metabolic disorders, including the risk of obesity and diabetes mellitus.

Two out of three Canadians are not aware of peripheral arterial disease (P.A.D.), a common vascular disease that affects as many as 800,000 Canadians, according to a study published in the Canadian Journal of Cardiology.
Commonly known as “hardening of the arteries,” P.A.D. occurs when arteries in the legs become narrowed or clogged with fatty deposits, reducing blood flow to the legs. As a result, P.A.D. may cause leg muscle pain when walking and lead to disability, amputation and a poor quality of life. The blocked arteries found in people with P.A.D. are a warning sign that other arteries, including those in the heart and brain, may also be blocked, increasing the risk of a heart attack or stroke.
In a cross-sectional, population-based telephone survey of 501 adults over age 50, researchers found that public awareness of P.A.D. (36 percent) is markedly lower than for other cardiovascular diseases such as stroke (72 percent), coronary artery disease (51 percent) and heart failure (48 percent). Yet, the risk for P.A.D. is equal to or greater than the risk for these conditions.
Few Canadians know that having P.A.D. significantly increases the risk for heart attack, stroke, amputation and death, the survey showed. Only one in five adults who were familiar with P.A.D. associates the disease with an increased risk of heart attack, stroke or death. Only 12 percent know that P.A.D. can lead to amputation.
P.A.D. affects both women and men and can strike adults of any age. The risk of P.A.D. is increased in people over age 50, particularly in smokers and former smokers, and in people with diabetes, high blood pressure, abnormal cholesterol and a personal history of heart disease or stroke.
“The study’s findings reinforce the need for national efforts to educate Canadians about peripheral arterial disease,” stated Marge Lovell, RN, lead author and clinical trials nurse at the London Health Sciences and Centre in London, Ontario. “If Canadians are not informed about P.A.D. and its devastating consequences, they will be less likely to take steps to avoid it.”
The study found that most Canadians do not know the causes or risk factors of P.A.D. Cigarette smoking and diabetes contribute to the development and progression of P.A.D., a fact unknown even by many survey respondents who reported familiarity with the disease. Further, half of those familiar with P.A.D. do not know that high blood pressure and high blood cholesterol are also risk factors.
In addition to Ms. Lovell, study authors are Kenneth Harris, MD, Thomas Forbes, MD, Beth Abramson, MD, Gwen Twillman, Paul Schroeder, MA, Emile R. Mohler, III, MD, Michael H. Criqui, MD, MPH, and Alan T. Hirsch, MD. The Canadian Journal of Cardiology is the official journal of the Canadian Cardiovascular Society, a member of the P.A.D. Coalition.
The P.A.D. Coalition funded the study through grants from Sanofi-Aventis Canada, Bristol-Myers Squibb and Cordis Endovascular, a division of Cordis Corporation.

About the P.A.D. Coalition
The Peripheral Arterial Disease (P.A.D.) Coalition is an alliance of more than 75 North American health organizations, professional societies, government agencies and corporations united to raise public and health professional awareness about lower extremity P.A.D. Established in 2004, the P.A.D. Coalition is a division of the Vascular Disease Foundation (www.vdf.org), a national, not-for-profit section 501(c)(3) organization. The P.A.D. Coalition seeks to improve the prevention, early detection, treatment, and rehabilitation of people with, or at risk for, P.A.D.
The neck arteries of obese children and teens look more like those of 45-year-olds, according to research presented at the American Heart Association’s Scientific Sessions 2008. “There’s a saying that ‘you’re as old as your arteries,’ meaning that the state of your arteries is more important than your actual age in the evolution of heart

You probably know that poor diet and lack of exercise can lead to dangerous deposits of fatty plaques in arteries. But it is not just the heart that is affected - blood flow can be blocked to the legs too, leading to pain when walking, immobility and even in extreme cases, amputation. Approximately 20% of us

Hispanic patients were 57 percent less likely than Caucasian patients to undergo coronary artery bypass surgery (CABG) one year after successful angioplasty, a type of percutaneous coronary intervention (PCI) to open blockages in the coronary arteries. Hispanics also had a trend toward lower rates of overall repeat revascularization procedures including stenting and bypass surgery, according

Chronic obstructive pulmonary disease (COPD) has a higher hospitalization rate and a higher hospital readmission rate than heart failure, angina, and other serious chronic diseases. Now, new survey results confirm that COPD affects many more Canadians than previously estimated (1.5 million) - and that 69 per cent of Canadians have not heard of COPD. In

Deep venous thrombosis (DVT), the formation of blood clots in the lower limbs, is the third-most common vascular disease in North America after heart attack and stroke, and is a frequent complication in hospitalized patients. DVT is a potentially serious condition that can lead to rapid death from pulmonary embolism if untreated, and has become
