While attending a conference for the American Heart Association in March, I had an interesting conversation with my doctoral mentor, Dr. Siddhartha Angadi. I am always in awe of his knowledge, as he’s only 35 years old and has a deep understanding of cardiovascular physiology – one to be revered by scientists of any scholar. We got on the topic of cardiovascular history, something I strongly believe worth sharing (you’ll understand by the time you finish reading).
In 1768, Dr. William Heberden made a profound statement regarding the treatment for those suffering from chest pain, which he appropriately named angina pectoris. His diagnostic exploration concluded with the following statement: “I knew one [patient] who set himself a task of sawing wood for half an hour every day, and was nearly cured.”
Heberden presented his accounts of angina to the Royal College of Physicians in London, England, describing causes, concerns, risks and treatments, all in an eloquently descriptive style of speech. The article outlining his findings was published in 1772, entitled “Some Account of a Disorder of the Breast.” For more than 250 years, we have known exercise prevents and reverses heart disease. Oh, how lost we have become. Pills, cars, screen time and TV dinner.
Some current statistics:
- According to the American Heart Association, the U.S. ranks 10th in the world for number of deaths due to CVD, and 1st among economically-developed countries.
- The leading cause of death in the U.S. (both men and women): CVD.
- Among the 24 nations that comprise the Organization for Economic Cooperation and Development (OECD), the U.S. spends the highest percentage of GDP on healthcare, roughly 17%.
In addition, there isn’t one simple answer to why the above statistical facts exist. It isn’t saturated fat or alcohol consumption (consider the French diet), or only genetics. However, the things we do know now Heberden wrote about long ago when medicine was beginning to find it’s way toward modernism.
- Alcohol is good for the cardiovascular system when consumed in moderation. Heberden’s account regarding chest pain: “Wine, and spirituous liquors, and opium afford considerable relief.”
- Stress has negative implications on health, including an increase risk for CVD-related mortality. Heberden states, “[Onset of angina pectoris] is increased by disturbance of the mind.”
- People live many years with atherosclerosis without knowing it. It may also begin in childhood, and is most prevalent in men. Heberden wrote, “There [exist] long intervals of perfect health… I have seen nearly a hundred people under this disorder, of which number there have been three women, and one boy twelve years old. All the rest were men near, or past the fiftieth year of their age.”
Most importantly, he knew, and we still know, exercise is the best free medicine for heart health. According to the current physical activity guidelines established by the U.S. Department of Health and Human Services, adults should aim to get 150 minutes of moderate intensity physical activity per week (or 75 minutes of vigorous activity per week, whichever you choose). This guideline is supported by a rich and sound plethora of scientific data, backed by the American College of Sports Medicine, the American Heart Association, Centers for Disease Control and Prevention, the Surgeon General, among others. In 2010, only 43.5% of Americans met the target amount of activity for health.
Time to chop wood, people!
