Autumn is here and the rain and wind may have you retreating to the sofa to snuggle with hot drinks rather than get out and about walking or exercising. However, the benefits of braving the cold may actually warm the heart! A new study (1) has found that any amount of physical activity appears to lower the risk of death among women and men with already diagnosed coronary heart disease. On the 31st July I wrote about physical activity and the prevention of cancer and with World Heart Day fast approaching (28th September) I thought it apt to mention this newly published study.
Individuals with heart disease frequently limit the amount of physical activity they partake in due to symptoms such as shortness of breath, chronic fatigue and circulatory problems. The researchers of this study wanted to investigate the long-term effects of exercise in individuals with existing heart disease. The study involved 14,021 people followed for an average of 14.7 years. The researchers categorised their physical activity into four levels – sedentary, mild, moderate and strenuous.
The results showed that the risk of death from cardiovascular problems increased significantly with less physical activity. The more active an individual was, the lower the risk of death from cardiovascular problems. This trend was similar in men and women. Over the course of the study, the death rate was lowest among men and women involved in strenuous recreation such as endurance activities or competitive team sports. The death rate was highest among men and women reporting sedentary leisure activities that primarily involved sitting. Sedentary individuals were 1.6 times more likely to die from cardiovascular disease or other causes over the long term compared to those more physically active.
The study concluded that “leisure-time physical activity independently predicted long-term survival in men and women with chronic stable CHD[coronary heart disease]”
If you suffer from heart problems ALWAYS make sure that you check with your GP or specialist before embarking on a new exercise regimen and seek advice on the best form of exercise for you to try. Walking and swimming are often recommended as good, gentle, ways to get started.
