Behavioural Cardiology at the Department of Psychology, Johannes Gutenberg-University Mainz, Germany

2008

Abstract. We provide a short overview of the research in Behavioural Cardiology at the Department of Psychology at the Johannes Gutenberg-University Mainz focussing on two lines of research: Studies of psychosocial variables that might enhance or attenuate cardiovascular risk in healthy individuals and studies of psychosocial variables and health behaviours that might impact the health status of patients listed for heart transplantation. Our studies so far suggest that psychosocial factors like anxiety and repressive coping impact information processing and cardiovascular responses to stress. Moreover, we examine the impact of health-protective resource variables including self-efficacy an…

Validity of epicardial fat volume as biomarker of coronary artery disease in symptomatic individuals: Results from the ALTER-BIO registry

2019

Abstract Background To determine if an increased epicardial fat volume (EFV) is associated with coronary artery disease (CAD) in individuals with symptoms of cardiovascular (CV) disease. Methods Coronary Computed Tomographic Angiography (CCTA), demographic and clinical variables of 1344 individuals were retrieved: semi-automated measurements for EFV and coronary artery calcifications (CAC) were obtained. Individuals were grouped into three categories according to the presence of CAD, resulting in absent (CAD0), non-obstructive (CAD1) or obstructive (CAD2) disease-groups. Relation of EFV with CAD was assessed with two approaches: 1) presence of any CAD; 2) each individual CAD category. Resul…

Hypertension is strongly associated with false-positive bicycle exercise stress echocardiography testing results

2016

Exercise echocardiography is a reliable routine test in patients with known or suspected coronary artery disease. However, in ∼15% of all patients, stress echocardiography leads to false-positive stress echocardiography results. We aimed to investigate the impact of hypertension on stress echocardiographic results.We performed a retrospective study of patients with suspected or known stable coronary artery disease who underwent a bicycle exercise stress echocardiography. Patients with false-positive stress results were compared with those with appropriate results.126 patients with suspected or known coronary artery disease were included in this retrospective study. 23 patients showed false-…

Variations in acoustical beam properties of intracoronary Doppler catheters.

1993

The limitations of coronary angiography in assessing the functional significance of coronary obstructions is well known. While the critical variable of coronary blood flow cannot be readily measured, intraluminal Doppler sonography offers useful related functional information on blood flow velocity. In order to fully evaluate Doppler signals it is essential to have exact knowledge of the transducer transmission characteristics and of the ultrasound beam topology. In an experimental set-up, the transmitter-receiver characteristics of five commonly used Doppler catheters were investigated. In comparing the beam characteristics we found inhomogeneities in the lateral beam spread. At a penetrat…

A rare case of a coronary artery anomaly detected on multidetector computed tomography

2013

An anomalous aortic origin of the coronary artery arising from the opposite sinus with an interarterial course is a rare condition that is associated with a high risk of sudden cardiac death during or after strenuous exertion. We herein report the case of a 47-year-old woman presenting with chest pain, syncope and palpitations who presented with a rare coronary artery anomaly on multidetector computed tomography coronary artery (MDCT-CA) with prospective electrocardiogram (ECG) gating.

Management of Coronary Artery Perforation

2020

Coronary artery perforation (CAP) is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI), however if recognized and managed promptly, its adverse consequences can be minimized. Risk factors for CAP include the use of advanced PCI technique (such as atherectomy and chronic total occlusion interventions) and treatment of severely calcified lesions. There are 3 major types of CAP depending on location: (a) large vessel perforation, (b) distal vessel perforation, and (c) collateral perforation. Large vessel perforation is usually treated with implantation of a covered stent, whereas distal and collateral vessel perforations are usually treated with c…

Thoracic Anesthesia during the 2019 Novel Coronavirus Infection Pandemic: 2021 Updated Recommendations for Airway Management by the EACTAIC Thoracic …

2021

Contains fulltext : 244115.pdf (Publisher’s version ) (Closed access) The novel coronavirus pandemic has radically changed the landscape of normal surgical practice. Lifesaving cancer surgery, however, remains a clinical priority, and there is an increasing need to fully define the optimal oncologic management of patients with varying stages of lung cancer, allowing prioritization of which thoracic procedures should be performed in the current era. Healthcare providers and managers should not ignore the risk of a bimodal peak of mortality in patients with lung cancer; an imminent spike due to mortality from acute coronavirus disease 2019 (COVID-19) infection, and a secondary peak reflecting…

Impact of COVID-19 pandemic on acute heart failure admissions and mortality: a multicentre study (COV-HF-SIRIO 6 study)

2022

Abstract Aims The coronavirus disease‐2019 (COVID‐19) pandemic has changed the landscape of medical care delivery worldwide. We aimed to assess the influence of COVID‐19 pandemic on hospital admissions and in‐hospital mortality rate in patients with acute heart failure (AHF) in a retrospective, multicentre study. Methods and results From 1 January 2019 to 31 December 2020, a total of 101 433 patients were hospitalized in 24 Cardiology Departments in Poland. The number of patients admitted due to AHF decreased by 23.4% from 9853 in 2019 to 7546 in 2020 (P < 0.001). We noted a significant reduction of self‐referrals in the times of COVID‐19 pandemic accounting 27.8% (P < 0.001), with increase…

Mortality associated with cardiovascular disease in patients with COVID-19

2020

Introducción y objetivos: Las enfermedades cardiovasculares (ECV) se han identificado como un factor de riesgo de mal pronóstico en pacientes con infección por COVID-19. Métodos: Se realizó un metanálisis de estudios actualmente disponibles con la prevalencia de ECV en supervivientes frente a no supervivientes en pacientes con infección por COVID-19 hasta el 16 de julio de 2020. Los análisis se realizaron mediante un modelo de efectos aleatorios y sensibilidad. Se realizaron análisis para identificar posibles fuentes de heterogeneidad o evaluar los efectos de los estudios pequeños. Resultados: Se incluyó a 307.596 pacientes de 16 estudios, de los que 46.321 (15,1%) tenían ECV. La tasa de mo…
