Preventing Diabetes & Heart Failure

Who is at risk for diabetes?

Family history is the main risk factor for type 1 diabetes. Many risk factors for type 2 diabetes are also risk factors for heart failure. Risk factors for type 2 diabetes include:

  • Obesity
  • Carrying body fat around the belly ("apple-shaped")
  • Family history of diabetes
  • Lack of exercise (fewer than 3 times a week)
  • Impaired glucose tolerance in an earlier diabetes test
  • Delivering a baby weighing more than 9 pounds or history of gestational diabetes
  • High blood pressure
  • Low HDL (good) cholesterol or high LDL (bad) cholesterol
  • Polycystic ovary syndrome
  • Certain ethnicities, including African American, Native American/Alaska Native, Asian American, Hispanic/Latino, and Native Hawaiian/Pacific Islander.

Diabetes is particularly widespread in African-American women, who are 50% to 60% more likely than white women to have heart failure, and develop heart failure at an earlier age.14

How can I prevent heart failure if I have diabetes?

The best way to prevent heart failure if you have diabetes is to get your high blood sugar levels under control and reduce your other risk factors. This means reducing your blood sugar, blood pressure, and cholesterol levels close to a normal value through lifestyle changes—especially diet and exercise—and medications, such as ACE inhibitors and angiotensin receptor blockers (ARB).15 The closer your numbers are to the optimal range, the better your chances are of preventing heart failure.

The ABCs of Diabetes Management

There are three major treatment goals to keep your diabetes under control: the ABCs of diabetes management. Following the ABCs of diabetes management lowers your risk of death due to diabetes and having complications of diabetes, including heart failure. Ask your doctor what your numbers are, what your individual goals should be, and what you need to do to reach and maintain them.

A is for A1C test (short for hemoglobin A1C). This simple blood test measures your average blood sugar over the last 3 months, and you should have it done at least twice a year. Aim to have an A1C level less than 7%.

B is for blood pressure. You should aim for a blood pressure less than 130/80. Have your blood pressure checked at every doctor’s visit.

C is for cholesterol. Aim to have your LDL (bad) cholesterol less than 100 mg/dL. Have your cholesterol checked at least once a year.

Your health care provider can help you develop a plan for things you should do every day to take care of your diabetes, including following a healthy eating plan (eat your meals and snacks around the same time each day) and being physically active for a total of 30 minutes most days. If you have diabetes, you are at higher risk for many other diseases and problems. In addition to treating the diabetes itself, it is important to reduce other risk factors you have and to keep an eye out for other medical problems related to diabetes (such as vision or foot problems).
