Consider lifestyle changes, drug therapy, family testing, and other measures to manage FH if diagnosed.
Facts & Figures
US (MEDPED) Diagnostic Criteria cutoff values compared to the general population:
|Total cholesterol cutpoints in mg/dL (mmol/L)|
|Age (years)||First Degree relative with FH||Second Degree relative with FH||Third Degree relative with FH||General Population|
|<20||220 (5.7)||230 (5.9)||240 (6.2)||270 (7)|
|20-29||240 (6.2)||250 (6.5)||260 (6.7)||290 (7.5)|
|30-39||270 (7)||280 (7.2)||290 (7.5)||340 (8.8)|
|≥40||290 (7.5)||300 (7.8)||310 (8)||360 (9.3)|
The US MEDPED (Make Early Diagnosis to Prevent Early Death) Diagnostic Criteria were constructed by Williams et al and published in 1993 by studying 207 patients in 5 large FH pedigrees in Utah and setting different cholesterol cut-off points for age. Using their predefined criteria, they diagnosed FH with 98% specificity and 87% sensitivity with confirmation from genetic testing.
