Women with Type 2 diabetes lose CVD protection

People with diabetes are twice as likely to suffer sudden cardiac death, a new report shows

Released by the Baker Heart and Diabetes Institute, The Dark Heart of Type 2 diabetes also reveals that developing Type 2 diabetes early in life is one of the greatest contributors to an early death.

It shows that cardiovascular disease is the top cause of death among Australians with Type 2 diabetes, and a major contributor to the shortening of life expectancy by close to a decade: 8.2 years for men, and 9.1 years for women.

It is responsible for one in three deaths in people with Type 2 diabetes, the report shows.

Report co-author and Head of Clinical Diabetes and Population Health at the Baker Institute, Professor Jonathan Shaw, says that while great strides have been made in controlling blood glucose levels and thereby reducing the associated risk of kidney disease, loss of sight and limb complications, “cardiovascular disease remains a clear and present threat for people with Type 2 diabetes”.

“The reality is that Australians with type 2 diabetes are much more likely to die from heart disease, and at a younger age, than those without the condition — regardless of whether their blood sugar levels are elevated or under control,” says Prof Shaw.

“Perhaps the greatest concern is the risk of sudden cardiac death which happens without warning, even among people with no history of heart disease. The importance of regular check-ups cannot be understated.”

And the number of people diagnosed with diabetes early in life is increasing rapidly, the report warns.

“Over the last decade, we have seen reductions in heart disease deaths in older Australians with diabetes, yet we have not seen the same improvements in those under the age of 40,” says Prof Shaw.

Having Type 2 diabetes has a greater effect on the risk of dying due to cardiovascular disease in women than in men, he says.

“It appears that the gender-associated protection against cardiovascular disease is lost in women with type 2 diabetes,” he says.

Contrary to popular belief, controlling blood glucose levels alone does not adequately protect people with diabetes from dying of cardiovascular causes, such as sudden cardiac deaths, heart attack, heart failure or stroke.

“While glucose-lowering medicines can protect against some of the consequences of diabetes, such as blindness and kidney damage, people with Type 2 diabetes remain at significant risk of cardiovascular disease and should speak to their doctors about lowering their risk,” Prof Shaw says.

The report recommends that as well as controlling blood sugar levels, people with Type 2 diabetes must also keep their blood pressure and cholesterol at healthy levels.

It also recommends patients adopt a healthy diet, moderate weight reduction, stop smoking and increase physical activity.

The report also found:

  • Diabetes is the fourth most common condition managed in general practice.
  • The lifetime risk of developing type 2 diabetes is one in three.
  • Type 2 diabetes is the leading cause of preventable cardiovascular disease.
  • An estimated two-thirds of Australians with type 2 diabetes also have cardiovascular disease.
  • Diabetes has a greater effect on the risk of death due to CVD in women than in men, as the gender-associated protection against CVD is lost in women with type 2 diabetes.
  • Aboriginal and Torres Strait Islander people with type 2 diabetes have a higher incidence of CVD and death from CVD.
  • The annual cost of diabetes for medical care and government subsidies in Australia exceeds $10 billion.

    Protection is important. I was diagnosed with type 2 Diabetes and put on Metformin on June 26th, 2017. I started the ADA diet and followed it 100% for a few weeks and could not get my blood sugar to go below 140. Finally i began to panic and called my doctor, he told me to get used to it. He said I would be on metformin my whole life and eventually insulin. At that point i knew something wasn’t right and began to do a lot of research. Then I found Lisa’s diabetes story (google ” How I freed myself from diabetes ” ) I read that article from end to end because everything the writer was saying made absolute sense. I started the diet that day and the next week my blood sugar was down to 100 and now i have a fasting blood sugar between Mid 70’s and the 80’s. My doctor took me off the metformin after just three week of being on this lifestyle change. I have lost over 16 pounds and 3+ inches around my waist in a month. The truth is we can get off the drugs and help myself by trying natural methods
