Heart disease is the number one killer in America and shows no sign of slowing down, particularly as the country continues to battle the obesity epidemic. There are a number of risk factors for the development of this condition, from obesity to sedentary lifestyles and more. However, a new study published from the Harvard School of Public Health is showing that a new potential marker could identify those that are most likely to be affected by the condition.


Blood Type and Heart Disease

According to the study, blood type may predict the chances of developing heart disease in some people. The study looked at 90,000 individuals and found that those with Type O blood have a natural protection in their blood which guards against heart disease. By comparison, people with types A, B or AB blood may have a higher risk of developing the condition over time. Of course, there are other protections against heart disease as well, including L-arginine. The benefits of arginine are well documented and have a host of other advantages in the body as well.


The risks according to blood type break down as such: those with Type AB have a 20% higher risk of heart disease, while those with Type B have a 10% higher risk of developing the disease, while those with Type A have a 5% higher risk of contracting the condition, than those with Type O blood type.


Lowering Heart Disease Risk

While you can’t change the type of blood you have, the point of the study is to show people their natural risk factors for developing heart disease, so that they might take advantage of other opportunities to low their risk. In addition to the benefits of arginine, for instance, those people with higher risk factors may also want to get more exercise, reduce stress and eat nutritiously to guard against the probably development of the condition.  However, knowing how your blood type factors in to the potential for the development of the disease ensures that you can take steps to stave it off. In other words, it allows you to gauge your risk and work with your doctor to reduce them so you are not caught off guard like many individuals are when dealing with heart disease; in fact, a lack of knowledge about the condition can be deadly for those that have it.


The benefits of arginine are far reaching. In addition to increasing the circulation in your heart muscles and allowing for greater blood flow, there are a number of other advantages to taking this supplement. A naturally-occurring amino acid, L-arginine can also help with joint ailments, aid in erectile dysfunction and assist with depression. While L-arginine is found in red meat and other nutritional food items, many people could use an extra boost to guard against conditions like heart disease, high blood pressure and more.


In addition to reaping the benefits of L-arginine, there are a number of other steps people can take to reduce their risk of developing heart disease. For example, smoking cessation for those that smoke can go a long way towards a more healthy lifestyle, as can maintaining a healthy weight and eating nutritiously. Researchers involved in the study have stated that the study encourages people to use their blood types as a wake call to become healthier and reduce risk factors where possible. It is important to keep in mind, however, the regardless of blood type and risk factors, it is important to get regular check-ups to stay on top of developments in the heart and body overall, as early detection can also be key to treating heart disease.
