Article Synopsis
  • Decreases in symptom severity and enhancements in quality of life are key objectives for treating patients with symptomatic chronic coronary syndrome (CCS) using invasive methods like PCI (Percutaneous Coronary Intervention).
  • A study involving 145 patients showed significant improvements in quality of life, physical limitation, and angina frequency six months post-PCI, with the most significant improvements seen in those with worse baseline health status.
  • Engaging in physical activity after the procedure further boosted quality of life improvements, indicating that patient health before treatment is crucial for outcomes, while demographic factors and psychological traits had minimal impact.

Background: Left atrial appendage closure (LAAC) is a mechanical alternative for stroke prevention in patients at risk who cannot tolerate oral anticoagulation (OAC).

Hypothesis: Our hypothesis was that the reduction of anticoagulation following LAAC results in a decrease of bleeding events and a rise in serum hemoglobin in a high-risk collective of patients with atrial fibrillation (AF).

Methods: Bleeding events, use of erythrocyte concentrates, anticoagulation, embolic events, and serum hemoglobin levels before and following LAAC were compared over more than 4 years.

Objective: Difficulties with dissociation and emotion regulation are well-documented reactions to early adverse childhood experiences (ACEs). Although findings identify dissociation and emotion dysregulation as explaining the relationship between various forms of ACEs and adult psychopathology, less is known about their combined effect in the relationship between ACEs and insecure attachment in adulthood. This study examined the indirect effects of dissociation and emotion regulation difficulties in the relationship between early adverse experiences and insecure attachment traits.

Objective: Interleukin-33 (IL-33) has been investigated as a mediator in the pathogenesis of fibrosis in lung, liver, and heart. There is accumulating evidence for the involvement of the IL-33/IL-33 receptor ST2L signalling pathway in systemic sclerosis (SSc). Little is known about the role of serum sST2 in SSc, which is the subject of the present investigation.

Aims: Chronic heart failure may lead to chronic kidney disease. Previous studies suggest tubular markers N-acetyl-b-D-glucosaminidase (NAG) and Kidney-injury-molecule-1 (KIM-1) as potential markers for the cardiorenal syndrome (CRS). The prognostic value of NAG and KIM-1 regarding implantable cardioverter defibrillator (ICD) shock therapies is unknown.

Heart transplantation is often an unrealizable therapeutic option for end-stage heart failure, which is why mechanical left ventricular assist devices (LVADs) become an increasingly important therapeutic alternative. Currently, there is a lack of information about molecular mechanisms which are influenced by LVADs, particularly regarding the pathophysiologically critical renin angiotensin system (RAS). We, therefore, determined regulation patterns of key components of the RAS and the β-arrestin signaling pathways in left ventricular (LV) tissue specimens from 8 patients with end-stage ischemic cardiomyopathy (ICM) and 12 patients with terminal dilated cardiomyopathy (DCM) before and after LVAD implantation and compared them with non-failing (NF) left ventricular tissue samples: AT1R, AT2R, ACE, ACE2, MasR, and ADAM17 were analyzed by polymerase chain reaction.

Grit, defined as passion and perseverance for long-term goals, predicts success in a number of social domains. The present two studies examined grit and its subscales, and how these relate to both adaptive and maladaptive personality traits pertaining to success. For Study 1, based on data from 249 participants, results indicated that grit was correlated positively with proactive personality, personal growth initiative, and competitiveness, and the perseverance subscale also was correlated positively with self- and other-oriented perfectionism.

Aim: Acute kidney injury (AKI) is often underdiagnosed due to several limitations of the renal marker creatinine. Tubular urinary biomarkers may substantially contribute to diagnose AKI early. For early detection of AKI, we evaluated for the first time N-acetyl-β-d-glucosaminidase (NAG), Kidney-injury-molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) in acute chest pain.

Implantation of left ventricular assist devices (LVADs) as bridge to transplant in end-stage heart failure allows for analyzing reverse remodeling processes of the supported heart. Whether this therapy influences the cGMP-PKG signaling pathway, which is currently under thorough investigation for developing new heart failure therapeutics, is unknown. In fourteen end-stage heart failure patients (8 with dilated cardiomyopathy, DCM; 6 with ischemic cardiomyopathy, ICM) tissue specimens of left ventricles were collected at LVAD implantation and afterwards at receiver heart explantation, respectively.

Background: Percutaneous mitral valve repair (PMVR) is increasingly performed in patients with severe mitral regurgitation (MR). Post-procedural MR grading is challenging and an unsettled issue. We hypothesised that the direct planimetry of vena contracta area (VCA) by 3D-transoesophageal echocardiography allows quantifying post-procedural MR and implies further prognostic relevance missed by the usual ordinal scale (grade I-IV).

About 50% of all patients suffering from heart failure (HF) exhibit a reduced ejection fraction (EF ≤ 40%), termed HFrEF. The others may be classified into HF with midrange EF (HFmrEF 40-50%) or preserved ejection fraction (HFpEF, EF ≥ 50%). Presentation and pathophysiology of HFpEF is heterogeneous and its management remains a challenge since evidence of therapeutic benefits on outcome is scarce.
