      NEW YORK (Reuters Health) - Deer hunting could be a dangerous endeavor for
      men with heart disease or risk factors for it, research findings suggest.

      In a study of 25 middle-aged male deer hunters, researchers found that the
      activities inherent to hunting -- like walking over rough terrain, shooting
      an animal and dragging its carcass -- sent the men's heart rates up
      significantly.

      In some cases, this led to potentially dangerous heart-rhythm disturbances,
      or diminished oxygen supply to the heart.

      Of the 25 hunters, 17 had established coronary heart disease, while the rest
      had risk factors such as being overweight, smoking or having high blood
      pressure or cholesterol.

      The findings suggest that for men like these, hunting could boost the risk
      of heart attack or cardiac arrest.

      Susan Haapaniemi and colleagues at William Beaumont Hospital in Royal Oaks,
      Michigan, report the findings in the American Journal of Cardiology.

      For the study, the researchers outfitted each man with a portable monitor
      that continuously recorded his heart's electrical activity during a day of
      deer hunting. For comparison, the men also had their hearts monitored as
      they exercised on a treadmill on a separate day.

      In general, the researchers found, deer hunting put the men's hearts under
      more strain than the treadmill did. Ten men exceeded the maximum heart rate
      they logged on the treadmill, and several showed potentially dangerous heart
      responses to hunting that they did not show during the treadmill test.

      Three men had signs of impeded blood flow to the heart during hunting, but
      not on the treadmill. Similarly, three of the men with heart disease had
      heart-rhythm abnormalities while hunting that did not show up on the
      treadmill test.

      The combination of physical exertion, adrenaline rush and the stress of
      rough terrain and cold weather may explain the "excessive cardiac demands"
      seen with hunting, according to Haapaniemi's team.

      What's more, they point out, most of the men in the study were taking part
      in an exercise program to treat their heart disease, or were regularly
      physically active. Hunting could be an even greater strain on the heart in
      men who are usually sedentary, the researchers note.
