Heart Guidelines Revised to Better Reflect Real Life


Heart disease is the leading cause of death in the United States, especially among women. The disease has been steadily rising among the most prevalent diseases for many years and the numbers continue to grow. The American Heart Association is now beginning to take new approaches to the prevention of heart disease by looking at the type of patients doctors regularly treat instead of the participants in clinical trials. Many of the participants of clinical trials are usually healthier than actual patients doctors see on a regular basis, so the American Heart Association is adjusting its recommendations for prevention and tailoring them more specifically for each individual. Not one list of things to do will work for every patient, so doctors are starting to individualize the treatment and prevention of heart disease. I believe this can also be applied to the community and calculating risk factors and preventative measures that could be taken by people within a community.

Public education of the risks that lead to heart disease are very important so that people that may be more susceptible can take necessary precautions. Everyone knows that being overweight and not exercising can lead to heart disease, but it is just as important to know that women that have had preeclampsia or rheumatoid arthritis also have an increased risk for heart disease. It is necessary to educate certain ethnicities of their risks to certain diseases. For example, African American women have high risk of hypertension and Hispanic women are particularly at risk for diabetes.

Women have to be extremely conscious of taking preventative measures because research shows they are much more at risk than men. 55,000 more women than men die from stroke each year. These preventative measures often have to be looked at by public health officials in the same way we were looking at our behavioral changes in class today. The same barriers exist for those trying to overcome their risk for heart disease as for those of us trying to exercise or eat fresh fruit. Women from lower income communities may not have the available resources to eat healthy all the time or exercise regularly at a gym. Not that the lack of a gym membership prevents exercise, but it is just another thing that can make a behavior change less convenient. Also, many women that are just trying to support their family and barely can get by are not going to be as willing to give a lot of thought to a disease that they do not even have and may never have. They are going to prefer to focus on the real pressing problems that have to be dealt with every single day. How do we find and educate them about things that can be done for their health without taking time out of their lives or costing any money?

There are many barriers to overcome in fighting this problem of making women aware of the risk they are at for disease like heart disease. Many people do not have health insurance and will not have the luxury of going to the doctor until they are actually sick. Educational programs need to be set up in the communities where high percentages of people do not have health insurance. What are some ways to make the general public aware of risk factors and preventative measures without a physical doctor visit? Heart disease is a killer disease, but it is also one that has many preventative measures. It should not take a doctor visit to make everyone aware of some of the simple steps that can be taken to prevent this disease, because honestly every single person is at risk. Overcoming the barriers to behavioral change is difficult for many people, but preventative measures that are more tailored to certain people is a good way to make these changes seem more attainable, and ultimately achieve a healthier population.

  1. This is interesting!
    I looked at the original version of the guidelines published in Circulation and saw a few interesting things. First, the article concluded that antioxidant supplementation (in the form of Vitamin E, C, or beta carotine) is not effective in either primary or secondary heart disease prevention. Also, Taking Aspirin once daily will not help prevent Heart Attacks in women under the age of 65.

    The study also looked at these guidelines from a global health perspective. Low and middle income countries account for 81%of deaths from cardiovascular disease. The guidelines committee determined that their recommendations (especially regarding risk assessment) could be effectively implicated in low and middle income countries.

    Something else that is worth noting, given our recent discussion of bio statistical methods, these recommendations are based on a massive amount of empirical data that was accumulated and evaluated for statistical relevance.

    Each recommendation was classified according to the strength of the recommendation and the level of the evidence. For example, the evidence suggesting that ingesting omega-3 fatty acids could be useful in primary and secondary heart disease prevention for women with high cholesterol or triglyceride levels was class B. This means that the evidence comes from only a single randomized trial or several poorly controlled trials.

  2. Interesting article and a very relevant take. I think in general we are seeing a rise in the trend towards specialized medical care for those who can afford it. Medical care has made "concierge services" more available as well. As we continue to find new advancements, I think the degree of specialization will only continue. Besides gender and ethnicity being taken into account, other attributes will be examined: profession, family structure, income, housing situation, lifestyle, diet, etc. Those things that we often consider on the fringe of medicine will have a heavier influence as drugs and antibiotics lose their dependability. Aspects like diet, stress management, and mental health all look to gain increasing prominence.

    With so many changes to the guidelines, I can't help but wonder how much of what we base our health decisions is either out-dated or was never correct in the first place? It's quite astounding and scary even to realize the degree of fallacy present in medical studies which inform the medical policy of these guidelines.

    And again like you said, I think the main point is all about finding solutions that are acceptable and attainable within an individual's own environment and lifestyle.
