Exercise affects men's, women's hearts differently: Study
CBS News
"Exercise physiology has been known to differ for men and women of different ages," said Dr.
Dr-Dori Naerbo's insight:

Doctors now use the formula "220 minus age" to determine how hard patients should work out during exercise stress tests. Many people also use this formula to set their target heart rate during workouts.

For the new study, a team led by Dr. Thomas Allison, director of stress testing at the Mayo Clinic in Rochester, Minn., reviewed 25,000 stress-test results. They saw significant differences between men and women.

 

Allison's group found that although peak heart rate declines with age for both sexes, the rate declines more gradually in women. This difference results in an overestimated peak heart rate in younger women and underestimated peak heart rate in older women, the researchers said.

 

The findings are scheduled for presentation Saturday at the annual meeting of the American College of Cardiology, in Washington, D.C.

Based on their findings, the study authors developed a new formula.

According to the revised formula, the maximum heart rate for women aged 40 to 89 should be 200 minus 67 percent of their age. For men, the preferred formula is 216 minus 93 percent of their age, the study authors said.

Interaction between genetic predisposition to obesity and dietary calcium in relation to subsequent change in body weight and waist circumference

Dr-Dori Naerbo's insight:

Studies indicate an effect of dietary calcium on change in body weight (BW) and waist circumference (WC), but the results are inconsistent. Furthermore, a relation could depend on genetic predisposition to obesity. Calcium may reduce WC among people genetically predisposed to a high WC.

Brands continue to target fast food marketing at kids

Brands continue to target fast food marketing at kids | heartmatters | Scoop.it
Companies are ploughing more and more money into marketing unhealthy foods to children. What will turn the tide?
Dr-Dori Naerbo's insight:

It is disheartening to see that  “junk food” companies are allowed to target children and worse, the pre-teen group!  In a free learning society in some countries this will have a huge impact as parents succumb to the will of their children.  As a result, childhood obesity will hit all time high, and we will end up outliving our children.  Why are we letting the kids have this junk?

 

Now it is time to stand up and educate the kids, we cannot leave it up to the companies that are targeting our children.   Food and sugar is the new drug of this century.  We need to start campaign in schools at a very early age just like anti-drug education.  

 

In addition, the schools need to make nutritious meals that taste good.  There was a program with Jamie Oliver in the US trying to make these changes.  Bravo for him and shame on the school district unwilling to make the changes for a healthier lifestyle.  

 

We need cool campaigns educating children on the dangers of fast foods and the importance of clean functional foods. Making functional food fun is a challenge; we have to go beyond boiling vegetables to death.  A segment of health classes could be to learn how to cook great functional foods that will tantalize and dance on your taste buds.  Ditch the elective cooking classes for mandatory lifestyle classes, which include, sex education, gastronomy, and healthy lifestyles.

American Heart Month: Women and men have major heart differences

American Heart Month: Women and men have major heart differences | heartmatters | Scoop.it
Some people may know heart attack symptoms differ in men and women, but more research shows significant anatomical differences that can affect diagnosis, treatment
Dr-Dori Naerbo's insight:

Finally, another study to prove what I have been trying to teach other women in my book about heart attacks.  Women do not present the same as men and most often they are silent attacks (no chest pain).  Additionally, when men have an angiogram to look for blockages it looks like a lump on a log whereas in women it can be diffuse and look like the walls are more narrow.  

 

Watch the video, learn the symptoms, many women in there 40s are having heart attacks.  It is not just something that happens to women over 60 years old.  I am still amazed at how many doctors (esp. female) still believe this and are not up-to-date with women's heart issues and the risk factors.  

 

Knowledge is power when you apply it in the right way. Be proactive, instead of reactive, learn the symptoms, use the right descriptors so you can get the help you need.  And please do not make  'light' of your symptoms, we all have an internal knowing about what is right in our bodies.  Start listening.  It is easy to say, I will get better, it will go away, its just a little ingestion, what if I go and its nothing then I will feel stupid.  So what! Better to go and be sure then damage your heart to the point of needing a transplant! Yes, that has happened before, many times.  Do let it happen to you.

Heart surgeon confesses processed food is slowly killing everyone

Dr. Dwight Lundell has dished the dirt on 'what really causes heart disease' and he admits prescribing cholesterol-lowering medications, and a low-fat, high-simple carbohydrate diet for two-and-a-half decades was misguided.
Dr-Dori Naerbo's insight:

Happy to see that some doctors are becoming enlightened and realising the old paradigm of prescribing drugs and certain diets do not work.

 

Make your food your medicine! The major food groups are along the side of the walls in a grocery store.  All the processed foods are in the middle, which are the sections to avoid.

A first-of-its-kind proposal in California would make companies put warnings about obesity and diabetes on sodas.
Dr-Dori Naerbo's insight:

The Journal of the American Medical Association (JAMA) recently published a study that found a significant relationship between added sugar consumption and increased risk for CVD mortality.  In addition, people who derive 25% of their daily calories from sugar are twice as likely to die from heart disease compared to people who take in just 7% of their calories from sugar. 

What do you think about the proposed warning labels?

You really CAN die of a broken heart: Losing a loved one doubles the risk of ...
Dr-Dori Naerbo's insight:
Research shows that you can die of a broken heart. Losing a loved one really can break your heart. Research shows that the risk of coronary failure or stroke doubles in the first month of bereavement.  Experts believe the findings show how important the ‘broken heart syndrome’ can be.

The researchers found that 0.16 per cent of patients experienced heart attacks or strokes within 30 days of their partner’s death – compared with 0.08 per cent of the normal population. Over the same period the risk of blood clots on the lungs was almost two and a half times greater.


Over the first three months, the risk of heart trouble or stroke was approximately a third higher, says a report in the journal, JAMA Internal Medicine. The researchers found a 25 per cent higher risk of death in the first year after bereavement among older couples, with a peak in the first three months.   Another study found the risk of early death increased for the surviving partner, and was much higher for widowers. But after the danger period of the first year, the bereaved can take comfort that the extra risk of dying declines.


To help cope with your feelings you may need extra support from friends and family, especially in the first month following bereavement when stress levels are particularly high. Scientists have said that divorce, operations and even winning the lottery are as likely as bereavement to trigger heart attacks.

CoQ10: The Longevity Factor

coenzyme Q10, mitochondria, mitochondrial theory of aging
Dr-Dori Naerbo's insight:

I am a huge fan of CoQ10 and have been taking 300 mg. everyday since my last MI.  CoQ10 has been life changing. As I have pointed out before, not all CoQ10s are created equal, so learn the difference, spend the extra money and get high quality.  

 

According to researchers CoQ10 is an essential component of the mitochondrial energy transfer system. When CoQ10 levels fall, mitochondrial dysfunction skyrockets, and ageing is accelerated.

Mitochondrial dysfunction is a term you will hear more often. It is the root cause of many diseases.

Major heart healing trial starts

Major heart healing trial starts | heartmatters | Scoop.it
Dr-Dori Naerbo's insight:

In this study, all the patients will have standard treatment to widen their narrowed arteries, and stents, half the patients will have stem cells taken from their bone marrow and injected into their heart.  

 

I have some reservations about this study.  First of all,  just widening and/ or stenting alone will give relief without stem cells, therefore it would be difficult to claim it was the stem cell alone.  Second, there is a window that is most suitable for delivery stem cells after MI according to several studies.  Third, the quantity and the quality of the stem cell will differ between each patient.  Fourth, there are conflicting reports regarding the potential for increased restenosis after stem cell transplantation. Fifth,  hopefully they will track the cells to see where they will eventually end up.  


I think they would have better outcomes if patients were optimised before treatment.  


Yes, while this is a great study, the real issue of why they got there in the first place should be addressed.
