CHICAGO -- Screening for cardiovascular problems in elite-level football players should begin in high school and continue throughout the lives of college and professional players. Mayo Clinic physicians based that conclusion on the results of their new study of the cardiovascular health of 233 retired National Football League (NFL) players.
The Mayo data showed that 82 percent of NFL players under age 50 had abnormal narrowing and blockages in arteries, compared to the general population of the same age. This finding suggests that the former athletes face increased risk of experiencing high blood pressure, heart attack or stroke. The report on research conducted by the Mayo Clinic Arizona group will be presented next week at the American College of Cardiology Annual Scientific Session in Chicago.
Significance of the Mayo Clinic Study
This is the first and largest study to measure comprehensive cardiovascular performance measures on retired NFL athletes, ages 35 to 65. Its findings add to the emerging portrait of poor heart health among this group of retired athletes. The findings also suggest that players as young as high school age who are engaged in serious competitive-conference level of training and play may benefit from regular cardiovascular screening. What we hope to emphasize with our findings is that all NFL players -- retired or not -- need to undergo cardiovascular health evaluation because they may have changes in heart and vessel conditions that we can treat so they dont experience problems later in life, says Robert Hurst, M.D., Mayo Clinic cardiologist and lead researcher.
Adds chair of cardiovascular diseases at Mayo Clinic in Arizona and researcher Bijoy Khandheria, M.D.: Cardiovascular screening is readily available and needs to become a routine part of serious football players health care, beginning at the high school level for those who are engaged in a highly competitive and rigorous level of training and play.
Football and Heart Problems
Previous research by various institutions and investigators in recent years showed concerning health trends:
Observing these serious trends, the Mayo Clinic researchers undertook the study to define vascular health and, by association, cardiovascular risk in retired NFL players. To determine vascular health, the Mayo team conducted multisite screening events with the help of players associations. Investigators measured the internal diameter of the carotid artery. They also assessed plaque deposits which can block blood flow.
The most striking results showed that:
The Mayo research team concluded that because test results showed evidence of asymptomatic narrowing of the arteries -- called atherosclerosis -- the retired NFL players are at abnormally high risk for an adverse cardiovascular event, as compared with people of the same age in the general population. In addition, the high incidence of plaque found in players vessels suggests that the increased narrowing is not solely due to increased body mass index. Further research is needed to explain this. In the meantime, football players will benefit from regular cardiovascular screening. Effective therapies are available to help players avoid serious cardiovascular problems later in life, but players need to take that first step of seeking out screening programs to identify those at risk, Dr. Khandheria says.
