At least this one actually defined moderate exercise so you could actually use this information. Maybe not so useful, previous CVD events were excluded from the research. I was doing high intensity exercise but still had a stroke. A great stroke association would complete this research with prior stroke patients. But that followup won't happen ever.

Moderate physical activity is associated with a greater than 50%
reduction in cardiovascular death in over-65s, according to research
presented at ESC Congress 2016 today.1 The 12 year study in nearly 2500
adults aged 65 to 74 years found that moderate physical activity reduced
the risk of an acute cardiovascular event by more than 30%. High levels
of physical activity led to greater risk reductions.
“The role of physical activity in preventing cardiovascular disease
(CVD) in people of working age is well established,” said Professor
Riitta Antikainen, professor of geriatrics at the University of Oulu,
Finland. “But relatively little is known about the effect of regular
physical activity on CVD risk in older people.”
The present study assessed the association between leisure time
physical activity and CVD risk and mortality in 2456 men and women aged
65 to 74 years who were enrolled into the National FINRISK Study between
1997 and 2007.
Baseline data collection included self-administered questionnaires on
physical activity and other health related behaviour, clinical
measurements (blood pressure, weight and height), and laboratory
measurements including serum cholesterol. Participants were followed up
until the end of 2013. Deaths were recorded from the National Causes of
Death Register and incident CVD events (coronary heart disease and
stroke) were collected from the National Hospital Discharge register.
The researchers classified self-reported physical activity as:
· Low: reading, watching TV or working in the household without much physical activity.
· Moderate: walking, cycling or practising other forms of light
exercise (fishing, gardening, hunting) at least four hours per week.
· High: recreational sports (for example running, jogging,
skiing, gymnastics, swimming, ball games or heavy gardening) or intense
training or sports competitions at least three hours a week.
During a median follow-up of 11.8 years, 197 participants died from CVD and 416 had a first CVD event.
When the researchers assessed the link between physical activity and
outcome they adjusted for other cardiovascular risk factors (blood
pressure, smoking and cholesterol) and social factors (marital status
and education). To minimise reverse causality, where worse health leads
to less physical activity, patients with coronary heart disease, heart
failure, cancer, or prior stroke at baseline were excluded from the
analysis.
The investigators found that moderate and high leisure time physical
activity were associated with a 31% and 45% reduced risk of an acute CVD
event, respectively (figure 1). Moderate and high leisure time physical
activity were associated with a 54% and 66% reduction in CVD mortality.
Professor Antikainen said: “Our study provides further evidence that
older adults who are physically active have a lower risk of coronary
heart disease, stroke, and death from cardiovascular disease. The
protective effect of leisure time physical activity is dose dependent –
in other words, the more you do, the better. Activity is protective even
if you have other risk factors for cardiovascular disease such as high
cholesterol.”
She concluded: “Physical exercise may become more challenging with
ageing. However, it is important for older people to still get enough
safe physical activity to stay healthy after their transition to
retirement.”
