Gender Differences and the Impact of Partnership and Children on Quality of Life During the COVID-19 Pandemic.

Objectives: The COVID-19 pandemic and its protective measures have changed the daily lives of families and may have affected quality of life (QoL). The aim of this study was to analyze gender differences in QoL and to examine individuals living in different partnership and family constellations. Methods: Data from the Gutenberg COVID-19 cohort study (N = 10,250) with two measurement time points during the pandemic (2020 and 2021) were used. QoL was assessed using the EUROHIS-QOL questionnaire. Descriptive analyses and autoregressive regressions were performed. Results: Women reported lower QoL than men, and QoL was significantly lower at the second measurement time point in both men and women. Older age, male gender, no migration background, and higher socioeconomic status, as well as partnership and children (especially in men), were protective factors for QoL. Women living with children under 14 and single mothers reported significantly lower QoL. Conclusion: Partnership and family were protective factors for QoL. However, women with young children and single mothers are vulnerable groups for lower QoL. Support is especially needed for women with young children.

Use of intravascular ultrasound for optimal vessel sizing in chronic total occlusion percutaneous coronary intervention.

Aim: The aim of this study is to provide evidence on how use of standardized intravascular ultrasound (IVUS) use impacts stent size choice in the setting of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) compared to visual estimation. Methods and results: Data of 82 consecutive patients who had successfully undergone IVUS-guided revascularization of CTO at the University Medical Center Mainz were analyzed. Angiography-based stent size prediction for the proximal and distal vessels was compared to the implanted stent diameter after IVUS assessment. Angiography-based stent size prediction for the proximal vessel was 3.09 ± 0.41, whereas IVUS use demonstrated larger vessel diameter, resulting in larger implanted stent diameter (3.24 ± 0.45, p < 0.001). Proximal vessel stent size prediction was underestimated in the majority of patients by angiographic estimation. Angiography-based stent size prediction for the distal vessel was 2.79 ± 0.38, whereas IVUS use demonstrated larger vessel diameter, resulting in larger implanted stent diameter (2.92 ± 0.39, p < 0.001). Conclusion: Pre-stent IVUS assessment in CTO PCI provides important information on vessel morphology and size. Angiography-based stent size prediction for the proximal and distal vessels was frequently underestimated, IVUS use demonstrated larger vessel diameter, resulting in significantly larger implanted stent diameter.

Environmental Noise-Induced Effects on Stress Hormones, Oxidative Stress, and Vascular Dysfunction: Key Factors in the Relationship between Cerebrocardiovascular and Psychological Disorders.

The role of noise as an environmental pollutant and its adverse effects on health are being increasingly recognized. Beyond its direct effects on the auditory system (e.g., hearing loss and tinnitus induced by exposure to high levels of noise), chronic low-level noise exposure causes mental stress associated with known cardiovascular complications. According to recent estimates of the World Health Organization, exposure to traffic noise is responsible for a loss of more than 1.5 million healthy life years per year in Western Europe alone, a major part being related to annoyance, cognitive impairment, and sleep disturbance. Underlying mechanisms of noise-induced mental stress are centered on increased stress hormone levels, blood pressure, and heart rate, which in turn favor the development of cerebrocardiovascular disease such as stroke, arterial hypertension, ischemic heart disease, and myocardial infarction. Furthermore, traffic noise exposure is also associated with mental health symptoms and psychological disorders such as depression and anxiety, which further increase maladaptive coping mechanisms (e.g., alcohol and tobacco use). From a molecular point of view, experimental studies suggest that traffic noise exposure can increase stress hormone levels, thereby triggering inflammatory and oxidative stress pathways by activation of the nicotinamide adenine dinucleotide phosphate oxidase, uncoupling of endothelial/neuronal nitric oxide synthase inducing endothelial and neuronal dysfunction. This review elucidates the mechanisms underlying the relationship between noise exposure and cerebrocardiovascular and psychological disorders, focusing on mental stress signaling pathways including activation of the autonomous nervous system and endocrine signaling and its association with inflammation, oxidative stress, and vascular dysfunction.

Everolimus-eluting bioresorbable scaffolds in patients with coronary artery disease: results from the German-Austrian ABSORB RegIstRy (GABI-R).

AIMS: The aim of this study was to analyse the procedural results and midterm safety of everolimus-eluting bioresorbable vascular scaffolds (BVS) used for percutaneous coronary intervention in a large all-comers cohort from the German-Austrian ABSORB RegIstRy (GABI-R). METHODS AND RESULTS: A total of 3,231 patients were included in this prospective, observational, multicentre study (ClinicalTrials.gov NCT02066623) of consecutive patients undergoing BVS implantation between November 2013 and January 2016. Endpoints were major adverse cardiac events (MACE; a composite endpoint of death, target vessel revascularisation, and myocardial infarction), and target lesion failure (TLF; a composite endpoint of cardiac death, target vessel myocardial infarction, and target lesion revascularisation). Scaffold thrombosis was a further endpoint. Of all patients, 51.5% presented with acute coronary syndrome. Predilatation and post-dilatation were performed in 91.5% and 71.9% of patients, respectively. Procedural success was 98.9%. After six months, the incidence of MACE was 4.1% and of TLF 2.4%. The rate of target vessel MI was 1.5%, and target lesion revascularisation was performed in 1.8%. Definite/ probable scaffold thrombosis was documented in 1.4% of patients. CONCLUSIONS: GABI-R, the largest registry to provide data regarding safety after BVS implantation in a real-world setting, reveals high procedural success and low six-month event rates.

Clinical restenosis and its predictors after implantation of everolimus-eluting bioresorbable vascular scaffolds: results from GABI-R.

AIMS: The aim of this study was to assess clinical restenosis and its predictors after implantation of bioresorbable vascular scaffolds (BVS) in everyday practice in the large-scale German-Austrian ABSORB Registry (GABI-R). METHODS AND RESULTS: Between November 2013 and January 2016, 3,264 patients underwent BVS implantation in the 93 centres of GABI-R. At six-month follow-up, 24 patients experienced clinically indicated target lesion revascularisation (cTLR) unrelated to BVS thrombosis (cumulative incidence 0.76%; angiographically, 58.3% of in-BVS restenosis of focal pattern). Compared to patients without cTLR, patients with cTLR had more lesions per patient (1.83±1.0 vs. 1.36±0.7), complex (52.3% vs. 36.2%) and mild-to-moderately calcified lesions (65.9% vs. 60.5%) treated, and more frequently had overlapping BVS (22.2% vs. 10.8%), all p<0.05. Implanted BVS length was 40.0 mm (28.0, 46.9) vs. 23.0 mm (18.0, 30.0), p<0.001, remaining in the multivariable analysis the only independent predictor of cTLR (hazard ratio 1.02, 95% CI: 1.01-1.04, p<0.001). The myocardial infarction rate was also significantly higher among patients with cTLR, 29.2% vs. 1.7%, p<0.0001. CONCLUSIONS: cTLR related to BVS restenosis at six months after BVS implantation is a rare event depending on implanted BVS length. Whether cTLR increases the myocardial infarction risk needs to be evaluated at longer-term follow-up and within the setting of adequately powered randomised trials.

Troponin I Assay for Identification of a Significant Coronary Stenosis in Patients with Suspected Acute Myocardial Infarction and Wide QRS Complex.

BACKGROUND: Common ECG criteria such as ST-segment changes are of limited value in patients with suspected acute myocardial infarction (AMI) and bundle branch block or wide QRS complex. A large proportion of these patients do not suffer from an AMI, whereas those with ST-elevation myocardial infarction (STEMI) equivalent AMI benefit from an aggressive treatment. Aim of the present study was to evaluate the diagnostic information of cardiac troponin I (cTnI) in hemodynamically stable patients with wide QRS complex and suspected AMI. METHODS: In 417 out of 1818 patients presenting consecutively between 01/2007 and 12/2008 in a prospective multicenter observational study with suspected AMI a prolonged QRS duration was observed. Of these, n = 117 showed significant obstructive coronary artery disease (CAD) used as diagnostic outcome variable. cTnI was determined at admission. RESULTS: Patients with significant CAD had higher cTnI levels compared to individuals without (median 250ng/L vs. 11ng/L; p<0.01). To identify patients needing a coronary intervention, cTnI yielded an area under the receiver operator characteristics curve of 0.849. Optimized cut-offs with respect to a sensitivity driven rule-out and specificity driven rule-in strategy were established (40ng/L/96ng/L). Application of the specificity optimized cut-off value led to a positive predictive value of 71% compared to 59% if using the 99th percentile cut-off. The sensitivity optimized cut-off value was associated with a negative predictive value of 93% compared to 89% provided by application of the 99th percentile threshold. CONCLUSION: cTnI determined in hemodynamically stable patients with suspected AMI and wide QRS complex using optimized diagnostic thresholds improves rule-in and rule-out with respect to presence of a significant obstructive CAD.

Treatment of coronary bifurcation lesions: stent-covering of the side branch with and without PCI of the side branch: a retrospective analysis of all consecutive patients.

BACKGROUND: Treatment of coronary bifurcation lesions is a complex problem. METHODS: This retrospective single-center study included all consecutive patients with PCI of coronary bifurcations with stent covering of the side branch (SB) between January 2008 - August 2011. RESULTS: Our study group (n = 98) was group A (n = 64, 65.3%) and group B (n = 34, 34.7%). Mean follow-up was 14.1 (group A) vs 12.3 (group B, p = ns) months. CONCLUSION: In patients with coronary bifurcations a simpler strategy has a significantly lower MACE. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01538186.

Thirty-one novel biomarkers as predictors for clinically incident diabetes.

BACKGROUND: The prevalence of diabetes is increasing in all industrialized countries and its prevention has become a public health priority. However, the predictors of diabetes risk are insufficiently understood. We evaluated, whether 31 novel biomarkers could help to predict the risk of incident diabetes. METHODS AND FINDINGS: The biomarkers were evaluated primarily in the FINRISK97 cohort (n = 7,827; 417 cases of clinically incident diabetes during the follow-up). The findings were replicated in the Health 2000 cohort (n = 4,977; 179 cases of clinically incident diabetes during the follow-up). We used Cox proportional hazards models to calculate the relative risk of diabetes, after adjusting for the classic risk factors, separately for each biomarker. Next, we assessed the discriminatory ability of single biomarkers using receiver operating characteristic curves and C-statistics, integrated discrimination improvement (IDI) and net reclassification improvement (NRI). Finally, we derived a biomarker score in the FINRISK97 cohort and validated it in the Health 2000 cohort. A score consisting of adiponectin, apolipoprotein B, C-reactive protein and ferritin almost doubled the relative risk of diabetes in the validation cohort (HR per one standard deviation increase 1.88, p = 2.8 e-5). It also improved discrimination of the model (IDI = 0.0149, p<0.0001) and reclassification of diabetes risk (NRI = 11.8%, p = 0.006). Gender-specific analyses suggested that the best score differed between men and women. Among men, the best results were obtained with the score of four biomarkers: adiponectin, apolipoprotein B, ferritin and interleukin-1 receptor antagonist, which gave an NRI of 25.4% (p<0.0001). Among women, the best score included adiponectin, apolipoprotein B, C-reactive protein and insulin. It gave an NRI of 13.6% (p = 0.041). CONCLUSIONS: We identified novel biomarkers that were associated with the risk of clinically incident diabetes over and above the classic risk factors. This gives new insights into the pathogenesis of diabetes and may help with targeting prevention and treatment.

Anticoagulant and/or antiplatelet treatment in patients with atrial fibrillation after percutaneous coronary intervention. A single-center experience.

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia sustained and frequently occurs in patients with coronary heart disease. Thus, a large number of patients requiring percutaneous coronary intervention (PCI) also suffer from AF. An anticoagulant regimen has not been standardized for patients with AF after coronary stent implantation. PATIENTS AND METHODS: The authors investigated data from 159 patients with AF who underwent PCI in their department. Baseline variables and incidence of a combined endpoint (stroke, myocardial infarction, cardiovascular death, severe bleeding) were compared in patients receiving clopidogrel and acetylsalicylic acid (ASA; group 1) versus patients receiving the combination of clopidogrel and ASA with low-molecular-weight heparin (LMWH; group 2) versus patients receiving the combination of clopidogrel and ASA with oral anticoagulation (OAC; group 3) at discharge. RESULTS: Patients discharged with triple therapy including OAC seemed to be at higher risk: patients in group 3 had decreased left ventricular ejection fraction and increased inflammatory state as measured by plasma fibrinogen and C-reactive protein. Moreover, previous OAC treatment and strokes were found more often in this subgroup of patients. In a median follow-up of 1.4 years, two severe bleeding events (both in group 1), four myocardial infarctions (all in group 1), 13 strokes (nine in group 1, four in group 2), and nine cardiovascular deaths (three in group 1, five in group 2, one in group 3) occurred. CONCLUSION: In this analysis, no treatment regimen seemed to be clearly superior. It underlines the importance of prospective, randomized trials to investigate the optimal antithrombotic/antiplatelet treatment for patients with AF after PCI.

Endothelin-1 in humans is increased by oxygen-derived radicals ex vivo and in vivo.

Endothelin-1, angiotensin II, and oxygen-derived radicals are pivotal factors in the development and progression of atherosclerosis. In vitro studies suggest that generation of oxygen-derived radicals by angiotensin II is an important mechanism increasing endothelin-1 synthesis, which consecutively may trigger effects such as cell proliferation and hypertrophy. The aim of this study was to confirm our previous data in an ex vivo and an in vivo setting. Explanted segments of internal mammary arteries were analyzed for big endothelin-1 expression following incubation with xanthine oxidase, angiotensin II, superoxide dismutase, and catalase to stimulate or to specifically inactivate oxygen-derived radicals. Endothelin-1 concentrations were determined by immunostaining and enzyme-linked immunosorbent assay. Further, oxypurinol was given to patients undergoing coronary angioplasty, a procedure known to increase plasma endothelin-1 concentrations. Angiotensin II and xanthine oxidase dose-dependently increased big endothelin-1 concentrations (p < .01 and p < .0001); the effects could be inhibited by coincubation with superoxide dismutase and catalase as determined by both semiquantitative immunofluorescence and enzyme-linked immunosorbent assay (p < .01). Patients undergoing coronary angioplasty exhibited significantly elevated big endothelin-1 concentrations 60 minutes after angioplasty (p = .03); in patients also receiving oxypurinol immediately after angioplasty, big endothelin-1 concentrations decreased (p = .001). Our results may explain the association between elevated angiotensin II levels, increased oxidative stress, and increased endothelin-1 concentrations in atherosclerosis. The data therefore support the concept that oxygen-derived free radicals stimulate the release of endothelin-1, which subsequently induces effects such as proliferation and enhanced agonist-induced vasoconstriction, previously attributed directly to angiotensin II.

Endothelin-1 mRNA and protein in vascular wall cells is increased by reactive oxygen species.

A dysregulated metabolism of oxygen-derived free radicals, nitric oxide and endothelin-1(ET-1) in conditions such as hypercholesterolaemia or hypertension may promote the development of atherosclerosis. We therefore subjected cultured human umbilical vein endothelial cells and coronary artery smooth muscle cells to oxidative stress induced by xanthine oxidase or hydrogen peroxide and observed alterations in ET-1 metabolism. Incubation with oxygen-derived free radicals increased preproET-1 promoter activity, ET-1 mRNA synthesis and big ET-1 concentrations in both cell types. This interaction of oxidative stress and ET-1 expression may be relevant in atherogenic conditions such as hypercholesterolaemia and hypertension since our data indicate that oxidative stress further aggravates the injurious effects attributed to ET-1.
