Men with cardiovascular risk factors more likely to develop peripheral artery disease

Among nearly 45,000 men who were followed up for more than two decades, those with the risk factors of smoking, hypertension, high cholesterol, and type 2 diabetes had an associated greater risk of developing PAD, according to a study in the October 24/31 issue of JAMA.

"Peripheral artery disease (PAD) is a distinct atherosclerotic syndrome marked by stenosis or occlusion [blockage] of the arteries, particularly of the lower extremities. PAD affects 8 to 10 million individuals in the United States, and is associated with reduced functional capacity and increased risk for cardiovascular morbidity and mortality. Despite its widespread prevalence and negative associations with quality of life, morbidity, and mortality, PAD remains underdiagnosed and undertreated," according to background information in the article. Preventable or treatable risk factors for PAD are generally thought to be similar to other forms of cardiovascular disease, however their respective associations with risk of PAD and the extent to which they are jointly associated with the incidence of PAD are not well established.

Michel M. Joosten, Ph.D., of Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, and colleagues conducted a study to estimate the individual and cumulative associations of the 4 conventional cardiovascular risk factors of smoking, hypertension, hypercholesterolemia, and type 2 diabetes with the risk of PAD among men. The study included 44,985 men in the United States without a history of cardiovascular disease at the beginning of the study in 1986; participants in the Health Professionals Follow-up Study were followed up for 25 years until January 2011. The presence of risk factors was updated biennially during follow-up.
