The Risk of Heart Failure Rises with Prediabetes
Prediabetes is
associated with cardiovascular disease, kidney
problems and, of course, diabetes. Prediabetes
is a precursor to type 2 diabetes. And diabetes
is highly associated with heart failure (HF). In
fact, one report
indicated that the risk of heart failure
in persons with diabetes is about double the
risk compared to those with normoglycaemia.
However, there remains doubt as to whether
prediabetes raises the risk of heart failure.
So, one
study was done to determine if there is a
relationship between prediabetes and HF, such
that those with prediabetes are at a higher risk
of HF.
The study was a meta-analysis consisting of 15
studies. The studies included 9,827,430
individuals. The researchers used definitions of
prediabetes established by the American
Diabetes Association (ADA), the World Health
Organization (WHO), and the International Expert
Committee (IEC). For their definitions, the
organizations used glucose-measurement ranges for
impaired fasting glucose (IFG), impaired glucose
tolerance (IGT), and elevated HbA1c.
The researchers determined that when an
individual had prediabetes as defined by the
above mentioned organizations, there was an
increased risk of heart failure when compared
with normoglycaemia.
The researchers concluded that “Prediabetes is
associated with an increased risk of HF. Future
studies are needed to evaluate effective
treatments for prediabetes to prevent the
development and progression of HF.” And since the National Diabetes Prevention Program
Lifestyle Change Program (National DPP LCP) can
delay or prevent type 2 diabetes, it may be
prudent to determine if the program can delay or
prevent HF.
A follow-on study
based on the original Diabetes Prevention
Program study has shown that participation in
the study did lower blood pressure. Perhaps,
collecting blood pressure measurements and other
cardiovascular data in DPP clinical settings
could lead to a tweaking of the DPP program that
could cause a delay or prevent HF in program
participants.
