Dr Anup Basuray (photo) presented a breakout session on a complex topic. The name Heart Failure does not in fact mean a heart has stopped working (my engineer/math husband is one of many who question the name Heart Failure – but this has been and remains our wording). The term is broad covering symptoms that occur when the heart is not fully functioning – leading to symptoms including shortness of breath, leg swelling, abdominal swelling, fatigue, and/or weight gain or loss. In his presentation, Prevent. Treat. Recover. : Transforming Heart Failure into a Success Story Dr. Basuray highlighted examples of young women patients he has treated. His case presentations illustrated the different ways people get heart failure; some specific to women, for example in the case of problems associated with pregnancy.

Heart Failure is diverse in cause, outcomes, and treatment. The slide here shows ~ 10 causes of Heart Failure, more recently identified is history of cancer treatment, and also included is ‘unknown‘ or doctor-speak, idiopathic. Heart valve disease, genetics (inherited causes), high blood pressure, drugs and alcohol, infection, coronary artery disease, pregnancy related, and irregular heart rate/rhythm can all be causes of Heart Failure.

Heart Failure results in fluid retention by the kidneys, a problem that is worse with high sodium diet. Western diets have high sodium – top sources are Breads and rolls, cold cuts and cured meats, pizza, poultry, soups, sandwiches, cheese, pasta dishes, meat dishes, SNACKS. Reading labels and being aware of sodium is key to heart health in general and to limiting fluid retention in Heart Failure in particular. Knowledge is power when considering what we eat – see here https://hearthealthdocs.com/heart-healthy-diet/  , and for surprising sources of salt https://hearthealthdocs.com/2016/06/08/surprise-sources-of-salt-in-your-diet/

Dr. Basuray addressed the power of prevention and how to stay healthy by knowing the following KEY modifiable risk factors for heart failure

  • High blood pressure
  • Diabetes
  • Obesity
  • High cholesterol

Know your numbers

  • Blood pressure, cholesterol, diabetes (blood glucose) screen
  • Every 4-6 years, as early as age 20

2013 AHA/ACC Heart Failure Guidelines 

So when should you learn about Heart Failure? Now is good. Same with choosing to live a heart healthier life.

Who Benefits from Fish, or Fish Oil? Some New Info on the Link to Heart Disease

IMG_8348rt5x7bwWhile we have known for some time about the potential benefits of fish in the diet, the specific role of supplements containing the beneficial component, omega-3 fatty acids, has been less clear, due to inconsistent results from various studies.

Fortunately, a new study released this month has clarified the link between supplementation with omega-3 fatty acids and the development of heart disease. This was actually a meta-analysis, meaning it summarized the data from multiple previous studies, in a manner that yields more information than the individual studies themselves. This was a very thorough analysis, specifically looking at the best quality studies (called randomized trials), and specifically looking at the useful component of omega-3 fatty acids, EPA and DHA. Moreover, the researchers were focused specifically on heart and circulatory complications.

What did they find? The intake of omega-3 fatty acids, either from food or supplements,fish-oil reduced the risk of heart disease by 6%. This reduction is mild, and was actually insignificant, but there was a significant decrease specifically patients who started out with high triglyceride levels (> 150 mg/dL) or LDL cholesterol (> 130 mg/dL). When the researchers included additional nonrandomized studies, the reduction in heart disease was 18%. Another important conclusion was that there does not appear to be any harmful effect of supplementation.

So what can we conclude?
First, supplementation with 1 g of omega-3 fatty acids daily, either from food or supplements, appears to be mildly beneficial in preventing heart and circulatory disease.
Second, the majority of the benefit is in patients who start out with elevation of triglyceride or LDL cholesterol. Previous studies (such as this) have shown that otherwise healthy patients derive minimal or no benefit from fish oil supplementation.
Third, there does not appear to be evidence of harm at this level of supplementation.

Also of note, more detailed studies are ongoing to determine the optimal level of supplementation and specific patients. Finally, keep in mind that there are other potential benefits of fish oil supplementation unrelated to heart disease, so if supplementation makes you feel better or healthier, it may be reasonable.  As always you should discuss your specific health situation with your doctor before considering any supplement or other therapy.
