Higher Resting Heart Rate May Boost Death Risk

Higher Resting Heart Rate May Boost Death Risk HealthDay 11/16/06 "study of more than 4,300 men, aged 42 to 53, found that those whose resting heart rate increased over five years were nearly 50 percent more likely to die over a 20-year span than men whose rate stayed the same or decreased...A long-term decrease in resting heart rate reduced death risk by nearly 20 percent...A resting heart rate of 60 to 80 beats per minute (bpm) is normal. People in excellent physical condition have a resting heart rate of about 40 to 50 bpm...cannot say for sure whether the increase in resting heart rate is only a marker for some other disease process or whether it is directly associated with mortality"

My hunch is that the resting heart rate is almost always tied to fitness levels and levels of SOD, CAT and GPX - internal antiox. enzymes that have profound effects on health. But it certainly does make sense that if you are fighting a chronic illness, or sudden powerful disease that the body might ramp up the heart rate. Anytime I've been ill, even with a cold, the bpm goes up.
