New research1 presented at the European Society of Cardiology Congress
in Barcelona shows that having a family history of cardiovascular disease (CVD)
is not enough to motivate people to follow healthy lifestyles.
Researchers used data from 188,139 users of HeartAge.me, a free online
tool that engages people presenting their personal CVD risk factors as their
estimated 'heart age', to test the hypothesis that those who have a family
history of CVD are more likely to attend medical examinations and blood
pressure checks and be motivated to adopt healthy diet and lifestyle habits.
38.5% of users reported a family history of CVD in at least one
parent, with 7% reporting a family history of CVD in two parents. Those who
reported that a parent had suffered with CVD were more likely to know their
blood pressure and cholesterol values than those without a family history of
CVD, suggesting that they were more likely to get tested regularly.
However, this awareness of risk factors did not translate into lower
CVD risk or healthier behaviours. Those who reported a family history of CVD
had higher heart ages (5.8 years older than real age) than those who did not
report family history (4.4 years older than real age). 25% of those who did not
report family history of CVD scored 'poor' on a diet and lifestyle index,
compared to 32% of users with family history of CVD in two parents.
Dr. Mark Cobain, Chief Science Officer at HeartAge who led the
research commented "Our research challenges the idea that a family history
of CVD may predispose individuals towards a healthier lifestyle. We see that
even though people with family history of CVD are more likely to know their
blood pressure and cholesterol numbers than those without, this alone does not
appear to motivate them to adopt healthier habits. This could be because they
believe that it is inevitable that they will develop CVD or doubt that it is
preventable through risk factor control."
He added "Previous research2 indicates that making CVD risk
personally relevant by giving an individual their heart age promotes behaviour
changes and improved outcomes. Such a strategy may prove effective in
communicating risk and motivating lifestyle change for those with a family
history of CVD."
Separate research3 from the same team, which was also presented at the
ESC Congress, highlighted the potential of small diet and lifestyle changes to
reduce CVD risk, suggesting that these changes could have similar, or even
greater effects than drugs such as statins or anti-hypertensives.
The modeling study looked at the impact of lifestyle changes including
following a healthy diet, losing weight, increasing physical activity and
giving up smoking on CVD risk expressed as a heart age. Key findings include
• For people with
hypertension (high blood pressure), adherence to a healthy diet could lower
heart age by on average 2-6 years; starting to take anti-hypertensives has a
similar effect with a reduction in heart age of 3 to 5 years.
• In overweight or obese
people, a 5-kilogram weight loss could reduce heart age by 2-4 years. Giving up
smoking could reduce heart age by an average of 13 years.
• In people with high
cholesterol, starting to use statins could reduce heart age with 3 to 6 years.
Since it was first launched in 2009, Heart Age has received widespread
support from healthcare professionals as a solution to help sustain behaviour
changes in multiple areas, such as healthy eating, increased physical activity
and smoking cessation. Local public health pilots are being conducted in the UK
in partnership with public health departments in local authorities, including
Shropshire Council and Bromley Council.
