Results of C-CHANGE
• Over 450 recommendations reduced
to 73 actionable items on
– Diagnosis
– Risk stratification
– Lifestyle measures
– Treatment including targets and monitoring
Lipid Treatment Targets
• Treatment target is based on the
person’s risk level.
– High or moderate risk: LDL-C <2.0
mmol/L or 50% in LDL-C; alternate
target: apoB<0.80 g/L.
– Low risk: If LDL-C ≥5.0 mmol/L, reduce
LDL-C ≥50%; apoB<0.90 g/L.
Physical Activity
• Adults aged 18-64 years and Older Adults 65 and
over should accumulate 150 minutes/week of
moderate intensity physical activity, or 90 minutes
of vigorous-intensity physical activity in periods of
at least 10 minutes each. Greater amounts of
activity and more vigorous activity provide
additional benefits.
• Engage in resistance activities on 2-4 days per
week.
• Engage in flexibility activities 4-7 days per week.
