Most Patients at Risk for Stroke Are Not Taking Preventive Steps

New Results From Kantar Health's National Health and Wellness Survey Show That Less Than 61% of High-Risk Patients Take Actions to Prevent Stroke

NEW YORK, NY--(Marketwire - May 23, 2011) - Less than half of US patients with atrial fibrillation (AF) are currently taking steps to avoid a stroke, according to new findings from the National Health and Wellness Survey (NHWS), conducted by Kantar Health and presented today at the 16th Annual International Meeting for ISPOR (International Society for Pharmacoeconomic and Outcomes Research) in Baltimore. AF is a major independent risk factor for stroke, and patients with AF have an approximately 5% annual risk for a stroke.

"We found that over 75% of patients with AF had a moderate or severe risk for a stroke," says Shaloo Gupta, M.S., Senior Research Analyst, Health Economics and Outcomes Research at Kantar Health. "Although the percentage of patients engaging in preventive behaviors increased with risk status, less than 61% of patients at high risk performed at least one of these behaviors."

Preventive stroke behaviors assessed in the NHWS included eating a low-fat diet, eating a low-sodium diet, exercising regularly, quitting smoking, losing weight, taking steps to lower blood pressure, taking steps to lower cholesterol, using clopidogrel, taking aspirin/baby aspirin, taking warfarin, and using other stroke-prophylactic medications. Although high-risk patients were more likely to engage in many of these preventive behaviors, they were no more likely to quit smoking, exercise regularly or eat a low-fat diet than patients at moderate or low risk.

"Although it has a low prevalence, stroke has been identified as one of the costliest conditions in the United States," Ms. Gupta says. "Our results suggest that most patients with AF are at a moderate to high risk for having a stroke, but many are doing very little to reduce their risk, including quitting smoking, exercising more regularly and eating a better diet. Increased patient education about stroke risk and prophylactic options may have enormous societal benefits."

Stroke risk was assessed with CHADS2, an index summing the presence of congestive heart failure, hypertension, age of 75 years or older, diabetes mellitus and history of prior stroke or transient ischemic attack.
