Abstract
The deadly quartet of the metabolic syndrome includes obesity, impaired glucose tolerance, an atherogenic lipid profile and hypertension. The synergistic effects of these comorbidities lead to a combination of functional and structural cardiomyocyte changes and finally result in a global adverse remodeling process. Overall cardiovascular outcome is significantly impaired. Furthermore, these changes increase the need for surgical or endovascular interventions and impair their outcomes. This is potentially due to current cardioprotective techniques being insufficiently tailored to the specific needs of these patients. The following review discusses the observed cardiomyocyte changes and systemic factors contributing to these changes. It describes the ensuing problems in cardioprotection and discusses strategies that can be taken to divert or circumvent these detrimental changes.

Prevalence of the metabolic syndrome rises rapidly.
Components of metabolic syndrome increase cardiovascular risk synergistically.
The metabolic syndrome leads to specific cardiomyocyte changes.
The natural course of the metabolic syndrome is detrimental.
The metabolic syndrome necessitates a tailored approach with correction of the individual risk factors and prevention of the hypertrophic and inflammatory stimuli.
New pharmacological insights might enable us to reactivate endogenous cardioprotective pathways in this high-risk population.
