title: Metabolic domino: new concept in lifestyle medicine.
abstract: A new concept has been proposed to capture the flow of events and chain reactions associated with cardiovascular risk: the metabolic domino. The metabolic domino differs for each individual based on their genetic predisposition. Lifestyle changes are the first dominoes to fall, which lead to obesity and insulin resistance, followed by postprandial hyperglycemia, hypertension, and hyperlipidemia. Atherosclerosis then begins, and diabetes occurs once the domino for impairment of insulin secretion has toppled. Progression of the atherosclerotic process can lead to cardiovascular events such as ischemic heart diseases or cerebrovascular disorders. Preclinical and clinical data indicate that treatments which inhibit the renin angiotensin system, such as angiotensin receptor blockers, can suppress the onset of diabetes and, when administered even earlier in the metabolic domino, reduce the development of hypertension in at-risk individuals. The inhibition of inflammation with thiazolidinedione can also block the sequence of events leading to cardiovascular outcomes, as was shown with pioglitazone in the Prospective Pioglitazone Clinical Trial in Macrovascular Events (PROactive).
