[Oxidative stress and cardiovascular diseases].
A number of diseases like hypercholesterolemia and atherosclerosis, hypertension, congestive heart failure, diabetes, ischemia-reperfusion, neurodegenerative diseases as well as acute and chronic inflammatory diseases are characterized by an increased steady-state concentration of reactive oxygen species (ROS). On a biomolecular level an enhanced oxidative stress causes damage of proteins, lipids and nucleic acids. Both the experimental and therapeutic efficiency of different antioxidative compounds (like various antioxidative enzymes) , drugs, metabolites and vitamins for the maintenance of an appropriate intracellular redox potential underline the importance of an excessive ROS-formation for these diseases. Control of excessive ROS-formation can be obtained by angiotensin converting enzyme (ACE-) inhibitors, by AT (1)-receptor blockers, by statins and other lipid lowering compounds, by improved expression of antioxidative enzymes (superoxide dismutase, catalase etc.), by compounds such as probucol, certain vitamins, pyruvate, by lipid apheresis and by physical exercise training, which displays surprising efficacy.
