Preventing Myocardial Injury Following Non-Cardiac Surgery: A Potential Role for Preoperative Antioxidant Therapy with Ubiquinone

Over 240 million non-cardiac operations occur each year and are associated with a 15–20% incidence of adverse perioperative cardiovascular events. Unfortunately, preoperative therapies that have been useful for chronic ischemic heart diseases, such as coronary artery revascularization, antiplatelet agents, and beta-blockers have failed to improve outcomes. In a pre-clinical swine model of ischemic heart disease, we showed that daily administration of ubiquinone (coenzyme Q10, CoQ10) enhances the antioxidant status of mitochondria within chronically ischemic heart tissue, potentially via a PGC1α-dependent mechanism. In a randomized controlled trial, among high-risk patients undergoing elective vascular surgery, we showed that NT Pro-BNP levels are an important means of risk-stratification during the perioperative period and can be lowered with administration of CoQ10 (400 mg/day) for 3 days prior to surgery. The review provides background information for the role of oxidant stress and inflammation during high-risk operations and the potential novel application of ubiquinone as a preoperative antioxidant therapy that might reduce perioperative adverse cardiovascular outcomes.

The Impact

Abstract Funding Acknowledgements Type of funding sources: None. Background. Falls among the elderly are a major cause of injury, significant disability and premature death. Hypotension is a potential risk factor for falls in older adults, especially patients with hypertension (HTN) taking antihypertensive drugs. Furthermore, the cardiovascular benefit of treatment of hypertension in older patients is clear, findings from observational studies have raised concerns that antihypertensive therapies in the elderly might also induce adverse effects, including injurious falls. In spite of the large number of issues related to this topic, the analysis of the causes of falls is insufficient. The aim of the study was to assess the frequency of falls and the impact of selected variables on the occurrence of risk of falls among patients with HTN. Material and methods. 100 patients, including 55 women, with HTN (mean age 69.4 ± 3.29 years) were enrolled into the study. The Tinetti test was used to assess the risk of falls. Sociodemographic and clinical data were obtained from the hospital register. Results. 89% of patients had a high risk of falls and 11% were prone to falls. The average number of falls during the last year in the study group was 1.86 ± 2.82 and in 30% of cases the fall was the cause of hospitalization. Single-factor analysis of the influence of selected variables on the risk of falls showed that higher values of SBP (-0.27; p = 0.007), DBP (-0.279; p = 0.005) and younger age of patients decrease the risk of falls (-0.273; p = 0.006). The linear regression model showed that independent predictors increasing the risk of falling are: use of diuretics (β=4.192; p < 0.001), co-occurrence of ischemic heart disease (β=4.669; p = 0. 007) and co-occurrence of heart failure (β=3.494; p = 0.016), and predictors reducing the risk of falling patients with hypertension are: the use of beta-blockers (β= -4.033; p = 0.013) and higher DBP value (β= -0.123; p = 0.016). Conclusions. Patients with HTN have a high risk of falling. Independent determinants increasing the risk of falling patients with HTN are the use of diuretics and the co-occurrence of ischemic heart disease or heart failure, while beta-blockers and a higher DBP value are factors reducing the risk of falling. Fall risk assessment and implementation of fall prevention should be carried out in everyday practice.
