The strategies
for control of the "first-stage" complications called NIDDM, AMI, stroke and
PVD, focus on addressing specific "intermediate" predictors, (for example raised
serum cholesterol, hypertension, smoking), do not address the root problem that underlies
the development of these risk indicators. A recent post-mortem study of 856 young American
adults aged 15-34 who died of external causes, and who had normal lipoprotein profiles
revealed that risk factors of hypertension, smoking, obesity and insulin resistance were
all associated with atheromatous lesions (Circulation, 2001, 103, 1546). Despite having
normal lipids, these young adults had moderate and in some cases advanced vascular
lesions. Those risk factors looked at in that study are part of the cluster of conditions
associated with metabolic syndrome and indicate that in the absence of lipid
abnormalities, vascular lesions are already developing. This means that our preventive
focus must be on factors that pre-date the development of dyslipidaemias. |
