| 1 | Exercise-mediated adaptations in vascular function and structure:Beneficial effects in coronary artery disease显示文摘Exercise exerts direct effects on the vasculature via the impact of hemodynamic forces on the endothelium,thereby leading to functional and structural adaptations that lower cardiovascular risk.The patterns of blood flow and endothelial shear stress during exercise lead to atheroprotective hemodynamic stimuli on the endothelium and contribute to adaptations in vascular function and structure.The structural adaptations observed in arterial lumen dimensions after prolonged exercise supplant the need for acute functional vasodilatation in case of an increase in endothelial shear stress due to repeated exercise bouts.In contrast,wall thickness is affected by rather systemic factors,such as transmural pressure modulated during exercise by generalized changes in blood pressure.Several mechanisms have been proposed to explain the exercise-induced benefits in patients with coronary artery disease(CAD).They include decreased progression of coronary plaques in CAD,recruitment of collaterals,enhanced blood rheological properties,improvement of vascular smooth muscle cell and endothelial function,and coronary blood flow.This review describes how exercise via alterations in hemodynamic factors influences vascular function and structure which contributes to cardiovascular risk reduction,and highlights which mechanisms are involved in the positive effects of exercise on CAD. | Xenofon M Sakellariou Michail I Papafaklis Eleni M Domouzoglou Christos S Katsouras Lampros K Michalis Katerina K Naka | 2021 | World Journal of Cardiology2021，13，9： | 1 |

| 4 | Elderly patients with non-cardiac admissions and elevated highsensitivity troponin:the prognostic value of renal function显示文摘BACKGROUND High-sensitivity cardiac troponin(hs-cTn)levels are frequently elevated in elderly patients presenting to the emergency department for non-cardiac events.However,most studies on the role of elevated hs-cTn in elderly populations have investigated the prognostic value of hs-cTn in patients with a specific diagnosis or have assessed the relationship between hs-cTn and comorbidities.AIM To investigate the in-hospital prognosis of consecutive elderly patients admitted to the Internal Medicine Department with acute non-cardiac events and increased hs-cTnI levels.METHODS In this retrospective study,we selected patients who were aged≥65 years and admitted to the Internal Medicine Department of our hospital between January 2019 and December 2019 for non-cardiac reasons.Eligible patients were those who had hs-cTnI concentrations≥100 ng/L.We investigated the independent predictors of in-hospital mortality by multivariable logistic regression analysis.RESULTS One hundred and forty-six patients(59%female)were selected with an age range from 65 to 100(mean±SD:85.4±7.61)years.The median hs-cTnI value was 284.2 ng/L.For 72(49%)patients the diagnosis of hospitalization was an infectious disease.The overall in-hospital mortality was 32%(47 patients).Individuals who died did not have higher hs-cTnI levels compared with those who were discharged alive(median:314.8 vs 282.5 ng/L;P=0.565).There was no difference in mortality in patients with infectious vs non-infectious disease(29%vs 35%).Multivariable analysis showed that age(OR 1.062 per 1 year increase,95%CI:1.000-1.127;P=0.048)and creatinine levels(OR 2.065 per 1 mg/dL increase,95%CI:1.383-3.085;P<0.001)were the only independent predictors of death.Mortality was 49%in patients with eGFR<30 mL/min/1.73 m2.CONCLUSION Myocardial injury is a malignant condition in elderly patients admitted to the hospital for non-cardiac reasons.The presence of severe renal impairment is a marker of extremely high in-hospital mortality. | Ioanna Samara Stavroula Tsiara Michail I Papafaklis Konstantinos Pappas Georgios Kolios Nikolaos Vryzas Lampros K Michalis Eleni T Bairaktari Christos S Katsouras | 2021 | World Journal of Cardiology2021，13，10： | 0 |
