Heart Attack
According to new research, exercise both reduces the risk of a heart attack and protects the heart from injury should a heart attack occur.
For years doctors have been trying to discover how this second benefit of exercise works. Now researchers at Emory University School of Medicine have found that the heart produces and stores nitric oxide (eNOS) - a short-lived gas which switches on the chemical pathways that relax blood vessels, increase blood flow and activate survival pathways.
The researchers found that exercise boosted levels of an enzyme that produces nitric oxide. Unlike other heart enzymes stimulated by exercise, researchers found that the eNOS levels in heart tissue stayed high for a week after exercise had ceased.
