Collagen type I degradation peptide as a predictive biomarker for mortality in ST-elevated myocardial infarction

Background and aims Tissue remodelling and extracellular matrix (ECM) changes are primary consequences of ST-elevated myocardial infarction (STEMI), leading to an increased risk of developing heart failure and mortality. Collagen type I is the top constituent of the cardiac ECM and is rapidly degraded at sites of tissue injury occurring in STEMI. We aimed to investigate the...

Modified essential frailty toolset for risk stratification in transcatheter mitral and tricuspid valve repair

Background Current guidelines recommend frailty assessment for risk stratification of candidates for transcatheter mitral and tricuspid valve repair (TMTVR), but it remains unclear which frailty score is most appropriate. Methods In a retrospective monocentric analysis of patients who received TMTVR, a modified version of the essential frailty toolset (EFT) was calculated from...

Associations between cardiovascular risk factors and diseases with aortic pulse wave velocity and aortic distensibility: magnetic resonance imaging in the Hamburg city health study

Background The role of cardiovascular magnetic resonance (CMR)-imaging-based pulse wave velocity (PWV) and aortic distensibility (AD) in population-based cohorts as a risk stratification tool remains unclear. The purpose of this study was the CMR-based quantification of PWV and AD in the context of cardiovascular risk factors (CVRF) and/or diseases (CVD) in the Hamburg City...

Antithrombotic therapy in infective endocarditis: Long-term clinical outcomes of a retrospective cohort study

Background Administering antithrombotic therapy (ATT) in patients with infective endocarditis (IE) involves a complex balance of bleeding and thromboembolic risks. Data on outcomes beyond the acute phase remain limited. This retrospective single-center cohort study had two aims: first, to describe the use of anticoagulation during the acute phase of left-sided IE; and second, to...

Neurocognition and health-related quality of life in patients randomized to surgical or transcatheter aortic-valve replacement

Background Severe symptomatic aortic stenosis is associated with increased morbidity and mortality. Surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) are established treatment options. Neurological complications such as subclinical cerebral ischemia, delirium, and postoperative cognitive decline can occur during either treatment; however...

Computed tomography-derived Hounsfield units for the differentiation between thrombosis and leaflet fibrosis in bioprosthetic heart valves

Purpose Our hypothesis was that computed tomography angiography (CTA)-derived Hounsfield units (HU) can differentiate between thrombosis and leaflet fibrosis (defined by a lack of response to oral anticoagulation) in patients with bioprosthetic heart valve dysfunction. Materials and methods Valvular leaflet HU were retrospectively assessed in 95 patients (derivation cohort...

Characteristics and outcomes of patients with heart failure and reduced left ventricular ejection fraction in relation to sodium-glucose cotransporter-2 inhibitor treatment: real-world data from the multicentre H2-registry

Background Heart failure (HF), including heart failure with reduced ejection fraction (HFrEF), remains a major public health issue with increasing disease burden. Recent advances, particularly data on sodium-glucose cotransporter-2 inhibitors (SGLT2i), have shifted HFrEF treatment paradigms based on strong evidence from randomised-controlled trials (RCTs). There is a lack of data...

In-hospital outcomes of intravascular lithotripsy compared to rotational atherectomy and cutting/scoring balloon angioplasty

Background Intravascular lithotripsy (IVL) emerged for the treatment of coronary artery calcification with encouraging safety and effectiveness rates in previous trials. Knowledge about the in-hospital safety of IVL in comparison to frequently used plaque modification techniques remains limited. Objectives The aim of this study was to assess the in-hospital outcomes of IVL in...

Diagnostic and prognostic value of regional wall motion abnormalities in patients with non-ST-elevation myocardial infarction

Background Beyond global left ventricular function, identification of regional wall motion abnormalities (RWMA) is an essential component of emergency echocardiography in patients with non-ST-elevation myocardial infarction (NSTEMI). This study investigated the prognostic significance and diagnostic value of RWMA. Methods Echocardiographies of 1110 consecutive NSTEMI patients...

Impact of catheter ablation on prognostic outcomes in electrical storm

Background Electrical storm (ES) is associated with high mortality and may lead to worsening of heart failure or repeat ICD therapy deliveries. Catheter ablation of ventricular tachycardia (VT) in ischemic heart disease has proven to be successful in reducing ventricular arrhythmia recurrences. The prognostic impact of ablation on patients with ES needs to be further elucidated...

Current treatment decisions in cardiac transthyretin amyloidosis: a multicentre analysis

Background The efficacy of transthyretin stabilisation in cardiac transthyretin amyloidosis (ATTR-CM) has been demonstrated in a clinical trial setting, but little is known about treatment decision-making in the real world. Particularly, initiating or discontinuing specific therapy is challenging in early and advanced disease. We evaluated current decision pathways for tafamidis...

Implementation of post-mortem examinations within a large population-based cohort: results from the Hamburg City Health Study

Background Full post-mortem examinations (conventional autopsies) are a valuable tool for understanding disease mechanisms but are commonly rare, especially in epidemiological research. This study aimed to (1) assess conventional autopsy implementation in the Hamburg City Health Study (HCHS), (2) identify factors associated with conventional autopsy performance, and (3) compare...

Predictive value of the NORPACS score for malignant ventricular arrhythmias in STEMI patients undergoing primary PCI

Background Malignant ventricular arrhythmias (MVA)—sustained ventricular tachycardia or fibrillation—remain a major early complication after ST-segment elevation myocardial infarction (STEMI) despite timely reperfusion. The no-reflow phenomenon is a key substrate for arrhythmogenesis. The no-reflow prediction in acute coronary syndrome (NORPACS) score, originally developed to...

Effect of vessel diameter on the clinical benefits of drug-coated balloon angioplasty: Insights from paclitaxel-coated balloon and polymer-free sirolimus-eluting stent studies

Background 20 years ago, drug coated balloon (DCB) angioplasty was introduced into the interventionalist’s toolbox initially to treat in-stent restenosis. Since then, considerable clinical evidence was generated in patients with de novo lesions. Whether drug-eluting stents (DES) or DCB angioplasty are associated with better clinical outcomes for de novo lesion treatment is still...

A practical guide to the management of dyslipidaemia

Dyslipidaemia, especially elevated low-density lipoprotein cholesterol (LDL-C), is a major modifiable risk factor for atherosclerotic cardiovascular disease (ASCVD). Dyslipidaemia remains underdiagnosed and undertreated. Dyslipidemia is highly prevalent in Germany. Even among patients with high- and very-high cardiovascular risk, LDL-C targets are often not achieved. This paper...
