Abstract
The burden of cardiovascular and metabolic diseases is increasing with every year. Although the management of these conditions has improved greatly over the years, it is still far from perfect. With all of this in mind, there is a need for new methods of prophylaxis and treatment. Coenzyme Q10 (CoQ10) is an essential compound of the human body. There is growing evidence that CoQ10 is tightly linked to cardiometabolic disorders. Its supplementation can be useful in a variety of chronic and acute disorders. This review analyses the role of CoQ10 in hypertension, ischemic heart disease, myocardial infarction, heart failure, viral myocarditis, cardiomyopathies, cardiac toxicity, dyslipidemia, obesity, type 2 diabetes mellitus, metabolic syndrome, cardiac procedures and resuscitation.

Abstract
The pharmacokinetics of the total pool of coenzyme Q(10) (Co(10)), its oxidized (ubiquinone) and reduced (ubiquinol, CoQ(10)H₂) forms have been investigated in rats plasma during 48 h after a single intravenous injection of a solution of solubilized CoQ(10) (10 mg/kg) to rats. Plasma levels of CoQ(10) were determined by HPLC with spectrophotometric and coulometric detection. In plasma samples taken during the first minutes after the CoQ(10) intravenous injection, the total pool of coenzyme Q(10) and proportion of CoQ(10)H₂ remained unchanged during two weeks of storage at -20°C. The kinetic curve of the total pool of coenzyme Q(10) corresponds to a one-part model (R² = 0.9932), while the corresponding curve of its oxidized form fits to the two-part model. During the first minutes after the injection a significant portion of plasma ubiquinone undergoes reduction, and after 7 h the concentration of ubiquinol predominates. The decrease in the total plasma coenzyme Q(10) content was accompanied by the gradual increase in plasma ubiquinol, which represented about 90% of total plasma CoQ(10) by the end of the first day. The results of this study demonstrate the ability of the organism to transform high concentrations of the oxidized form of CoQ(10) into the effective antioxidant (reduced) form and justify prospects of the development of parenteral dosage forms of CoQ(10) for the use in the treatment of acute pathological conditions.

Abstract
Periodontal disease is an inflammatory disease process resulting from the interaction of a bacterial attack and host inflammatory response. Arrays of molecules are considered to mediate the inflammatory response at one time or another, among these are free radicals and reactive oxygen species (ROS). Periodontal pathogens can induce ROS overproduction and thus may cause collagen and periodontal cell breakdown. When ROS are scavenged by antioxidants, there can be a reduction of collagen degradation. Ubiquinol (reduced form coenzyme Q10) serves as an endogenous antioxidant which increases the concentration of CoQ10 in the diseased gingiva and effectively suppresses advanced periodontal inflammation.

Abstract
Co-Q10 is a lipid-soluble benzoquinone that is an important factor in free radical scavenging, mitochondrial membrane stability and ATP synthesis. Dietary Co-Q10 is a powerful antioxidant that has been useful in lessening the damage associated with ischemia-reperfusion injuries and aiding in the recovery of myocardial function after myocardial infarction. However, the role of dietary Co-Q10 in oxidative damage and repair is not well understood. Previous LC-EC methods have used packed carbon bed electrodes with high overpotentials that were sufficient to oxidize and reduce several biological compounds, thereby decreasing the selectivity that can be achieved with EC detection. Thin-layer cell dual electrode detection enables monitoring of reduced and oxidized forms of Co-Q10 simultaneously and selectively. The oxidation (+0.45 V vs. Ag/AgCl) and reduction (-0.4 V vs. Ag/AgCl) electrode potentials were optimized to oxidize and reduce the electroactive quinone moiety. The reduced form of Co-Q10 was prepared from the commercially available oxidized form using a Jones reductor. Confirmation of its formation was determined using the current ratios of the peak and half wave potentials from previously generated hydrodynamic voltammograms, using the oxidized form with electrodes in a series configuration. This analytical system was successfully applied to determine basal concentrations of oxidized (510 nM) and reduced (500 nM) Co-Q10 in human plasma. Peak identity of oxidized and reduced Co-Q10 was confirmed by two orthogonal methods: by the current ratios at +0.45 V and +0.25 V and -0.4 V and -0.2 V (vs. Ag/AgCl) as well as by retention time. Detection limits were determined to be 5 nM, with a linear range of three orders of magnitude.

Abstract
A wealth of research data points to increased oxidative stress as a key driver of the cardiac remodeling triggered by chronic pressure overload, loss of functional myocardial tissue, or atrial fibrillation. Oxidative stress is a mediator of the cardiomyocyte hypertrophy and apoptosis, the cardiac fibrosis, and the deficits in cardiac function which typify this syndrome, and may play a role in initiating and sustaining atrial fibrillation. Nox2- and Nox4-dependent NADPH oxidase activity appears to be a major source of this oxidative stress, and oxidants can induce conformational changes in xanthine dehydrogenase, nitric oxide synthase, and the mitochondrial respiratory chain which increase their capacity to generate superoxide as well. Consistent with these insights, various synthetic antioxidants have been shown to suppress cardiac remodeling in rodents subjected to myocardial infarction, aortic constriction, or rapid atrial pacing. It may prove feasible to achieve comparable benefits in humans through use of a "full-spectrum antioxidant therapy" (FSAT) that features a complementary array of natural antioxidants. Spirulina is a rich source of phycocyanobilin, a derivative and homolog of biliverdin that appears to mimic the potent inhibitory impact of biliverdin and free bilirubin on NADPH oxidase activity. Mega-doses of folate can markedly increase intracellular levels of tetrahydrofolates which have potent and versatile radical-scavenging activities - including efficient quenching of peroxynitrite-derived radicals Supplemental coenzyme Q10, already shown to improve heart function in clinical congestive failure, can provide important antioxidant protection to mitochondria. Phase 2 inducer nutraceuticals such as lipoic acid, administered in conjunction with N-acetylcysteine, have the potential to blunt the impact of oxidative stress by boosting myocardial levels of glutathione. While taurine can function as an antioxidant for myeloperoxidase-derived radicals, its positive inotropic effect on the failing heart seems more likely to reflect an effect on intracellular calcium dynamics. These measures could aid control of cardiac modeling less directly by lowering elevated blood pressure, or by aiding the perfusion of ischemic cardiac regions through an improvement in coronary endothelial function. Since nitric oxide functions physiologically to oppose cardiomyocyte hypertrophy and cardiac fibrosis, and is also a key regulator of blood pressure and endothelial function, cocoa flavanols - which provoke endothelial release of nitric oxide - might usefully complement the antioxidant measures recommended here.

Abstract
Comprehensive management of patients with chronic ischemic disease is a critically important component of clinical practice. Cardiac myocytes have the potential to adapt to limited flow conditions by adjusting contractile function, reducing metabolism, conserving resources, and preserving myocardial integrity to cope with an oxygen and (or) nutrition shortage. A prime metabolic feature of cardiac myocytes affected by chronic ischemia is the return to a fetal gene pattern with predominance of carbohydrates as the substrate for energy. Structural adaptation with multiple intracellular changes is part of the remodeling process in hibernating myocardium. Transmural heterogeneity, which defines the pattern of injury in ventricular cardiomyocytes and the response to chronic ischemia, is a multifactorial process originating from functional, metabolic, and flow differences in subendocardial and subepicardial regions. Autophagy is typically activated in hibernating myocardium and has been identified as a prosurvival mechanism. Chronic ischemia is associated with changes in the number, size, and distribution of gap junctions and may give rise to conduction disturbances and arrhythmogenesis. Differentiation between viable and nonviable myocardium by assessing sensitivity of inotropic reserve is a crucial diagnostic tool that is correlated with the prognosis and outcome for improved contractility after restoration of blood perfusion in afflicted myocardium.Reliable and accurate diagnosis of ischemic, scar, and viable tissues is critical for recover strategies. Although early surgical reinstitution of blood flow is most effective in restoring physiologic function of the hibernating myocardium, several new approaches offer promising alternatives. Among others, vascular endothelial growth factor and fibroblast growth factor-2 (FGF-2), especially its lo-FGF-2 isoform, have been shown to be effective in rapid neovascularization. Substances such as statins, resveratrol, some hormones, and omega-3 fatty acids can improve recovery effect in chronically underperfused hearts. For patients with drug-refractory ischemia, intramyocardial transplantation of stem cells into predefined areas of the heart can enhance vascularization and have beneficial effects on cardiac function. This review of ischemic injury, its heterogeneity, accurate diagnosis, and newer methods of treatment, shows there is much information and tremendous hope for better management of patients with coronary heart disease.
