Blood Pressure and Mortality in the 4D Study.

Kidney Blood Press Res

December 2023

Fifth Department of Medicine, University Medical Center Mannheim UMM, Faculty of Medicine of the University of Heidelberg, Mannheim, Germany.

Introduction: Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) are risk factors for cardiovascular mortality (CVM). Pulse pressure (PP) is an easily available parameter of vascular stiffness, but its impact on CVM in chronic dialysis patients with diabetes is unclear.

Methods: Therefore, we have examined the predictive value of baseline, predialytic PP, SBP, DBP, and MAP in the German Diabetes and Dialysis (4D) study, a prospective, randomized, double-blind trial enrolling 1,255 patients with type 2 diabetes on hemodialysis in 178 German dialysis centers.

September 2023

Department of Cardiovascular Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Okayama, Japan.

Article Synopsis
  • Transplanting human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) shows promise for treating heart failure, but there's a need for reliable long-term monitoring methods post-transplant.* -
  • The study introduced a sodium/iodide symporter (NIS) into human iPSCs and used nuclear medicine imaging to track the engraftment of these cells in immunodeficient rats over time.* -
  • NIS-expressing iPSC-CMs were successfully tracked with imaging, but it was found that NIS expression impacted the growth and proliferation of the cells, indicating the need for more research on its effects.*

Aims: Myocardial work (MyW) is an echocardiographically derived parameter to estimate myocardial performance. The calculation of MyW utilizes pressure strain loops from global longitudinal strain and brachial blood pressure (BP) as a surrogate of left ventricular systolic pressure (LVSP). Since LVSP cannot be equated with BP in hypertrophic obstructive cardiomyopathy (HOCM), we explored whether LVSP can be derived non-invasively by combining Doppler gradients and BP.

Article Synopsis
  • Women hospitalized for acute heart failure (AHF) are generally older and have more health complications but receive less diagnostic testing and treatment compared to men.
  • In low-income countries with less income disparity, women have better one-year survival rates than men, but this advantage diminishes in areas with greater income inequality.
  • The study highlights a critical need for equitable heart failure care across genders, as disparities in treatment and outcomes persist globally, particularly in lower-income regions.

Diagnosing post-capillary hypertension in patients with left heart disease: impact of new guidelines.

Clin Res Cardiol

September 2023

Department of Internal Medicine, Respiratory Medicine and Ventilatory Support, Medical Mission Hospital, Central Clinic Würzburg, Würzburg, Germany.

Background: In 2022, the definition of pulmonary hypertension (PH) in the presence of left heart disease was updated according to the new joint guidelines of the European Society of Cardiology (ESC) and the European Respiratory Society (ERS). The impact of the new ESC/ERS definition on the prevalence of post-capillary PH (pc-PH) and its subgroups of isolated post-capillary (Ipc-PH) and combined pre- and post-capillary PH (Cpc-PH) in patients with left heart disease is unclear.

Methods: We retrospectively identified N = 242 patients with left heart disease with available data on right heart catheterisation (RHC) and cardiac magnetic resonance imaging (CMR).

Pain is prevalent among patients with diabetes and chronic kidney disease (CKD). The management of chronic pain in these patients is limited by nephrotoxicity of commonly used drugs including non-steroidal anti-inflammatory drugs (NSAIDs) and opioids. Since previous studies implicated endothelin-1 in pain nociception, our post hoc analysis of the SONAR trial assessed the association between the endothelin receptor antagonist atrasentan and pain and prescription of analgesics.

Aims: Hospital admission during nighttime and off hours may affect the outcome of patients with various cardiovascular conditions due to suboptimal resources and personnel availability, but data for acute heart failure remain controversial. Therefore, we studied outcomes of acute heart failure patients according to their time of admission from the global International Registry to assess medical practice with lOngitudinal obseRvation for Treatment of Heart Failure.

Methods And Results: Overall, 18 553 acute heart failure patients were divided according to time of admission into 'morning' (7:00-14:59), 'evening' (15:00-22:59), and 'night' (23:00-06:59) shift groups.

Article Synopsis
  • The LeoDOR trial tested if a medicine called levosimendan helps people recover better after being in the hospital for heart failure.
  • It included a mix of patients who were given either levosimendan or a fake medicine (placebo) to see if it worked over 12 weeks.
  • The results showed that levosimendan didn’t make a big difference in recovery compared to the placebo, and some patients on it had more problems than those on the fake medicine.

A complementary safety assessment of the specific absorption rate (SAR) of the electromagnetic energy was performed in a prototype 8Tx/16Rx RF array for cardiac magnetic resonance imaging (MRI) at 7 T. The study aimed to address two critical aspects of 7-T SAR safety not always explicitly examined by coil vendors: (i) the influence of an RF-array position on a peak SAR value, and (ii) the risk of exceeding the permitted maximal SAR in the tissue surrounding conductive passive implants. The full-wave 3D electromagnetic simulations for the thorax with shifted array position and the whole-body volume in the presence of a dental retainer, an intrauterine contraceptive device (IUD), and a hip joint implant, were performed for two human voxel models.

Purpose: Functional cardiac MRI scans employing balanced steady-state free precession sequences suffer from dark band artifacts in the myocardium due to B inhomogeneity. We recently introduced a novel method for the theoretical derivation of B distributions in the human heart. This study aims to simulate the B distributions in the heart across the cardiac cycle using structural MR images and validate the simulations via in vivo measured cardiac phase-specific B maps on the same subjects at 3T.

Background: Performance anxiety is the most frequently reported anxiety disorder among professional musicians. Typical symptoms are - on a physical level - the consequences of an increase in sympathetic tone with cardiac stress, such as acceleration of heartbeat, increase in blood pressure, increased respiratory rate and tremor up to nausea or flush reactions. These symptoms can cause emotional distress, a reduced musical and artistical performance up to an impaired functioning.

  • CARD9 is an important signaling molecule in macrophages, but its function in atherosclerosis is still not well understood.
  • Deletion of the CARD9 gene leads to increased atherosclerosis in specific mouse models, indicating that it helps protect against this condition independent of the adaptive immune system.
  • CARD9 deficiency affects macrophage behavior by promoting inflammation and lipid accumulation, but treatments like rapamycin or metformin can reverse these effects and help restore normal macrophage functions.

Differential network interactions between psychosocial factors, mental health, and health-related quality of life in women and men.

Sci Rep

July 2023

Translational Social Neuroscience Unit, Department of Psychiatry, Psychosomatic and Psychotherapy, Center of Mental Health, University Hospital Würzburg, Margarete-Höppel-Platz 1, 97080, Würzburg, Germany.

Psychosocial factors affect mental health and health-related quality of life (HRQL) in a complex manner, yet gender differences in these interactions remain poorly understood. We investigated whether psychosocial factors such as social support and personal and work-related concerns impact mental health and HRQL differentially in women and men during the first year of the COVID-19 pandemic. Between June and October 2020, the first part of a COVID-19-specific program was conducted within the "Characteristics and Course of Heart Failure Stages A-B and Determinants of Progression (STAAB)" cohort study, a representative age- and gender-stratified sample of the general population of Würzburg, Germany.

Background: Invasive cardiac output (CO) is measured with the thermodilution (TD) or the indirect Fick method (iFM) in right heart catheterization (RHC). The iFM estimates CO using approximation formulas for oxygen consumption ([Formula: see text]O), but there are significant discrepancies (> 20%) between both methods. Although regularly applied, the formula proposed by Krakau has not been validated.

The presence of multiple pathogenic variants in desmosomal genes (DSC2, DSG2, DSP, JUP, and PKP2) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) has been linked to a severe phenotype. However, the pathogenicity of variants is reclassified frequently, which may result in a changed clinical risk prediction. Here, we present the collection, reclassification, and clinical outcome correlation for the largest series of ARVC patients carrying multiple desmosomal pathogenic variants to date (n = 331).
