Background: Papillary muscle-delayed hyperenhancement (papHE) at cardiac magnetic resonance indicates fibrotic or infiltrative processes. Contrary to myocardial HE, the prevalence and prognostic implications of papHE in patients with nonischemic dilated cardiomyopathy are unclear.

Objectives: The purpose of this study was to determine the prevalence of papHE and describe its association with adverse clinical outcomes.

Aims: Recently, novel post-processing tools have become available that measure intraventricular pressure gradients (IVPGs) on routinely obtained long-axis cine cardiac magnetic resonance (CMR) images. IVPGs provide a comprehensive overview of both systolic and diastolic left ventricular (LV) functions. Whether IVPGs are associated with clinical outcome after ST-elevation myocardial infarction (STEMI) is currently unknown.

Objectives: Systemic sclerosis (SSc) is characterized by multiple clinical manifestations. Vasculopathy is a main disease hallmark and ranges in severity from an exacerbated Raynaud phenomenon to pulmonary arterial hypertension (PAH). The potential involvement of the immune system in SSc-associated vascular abnormalities is not clear.

Aims: Systemic sclerosis (SSc) is characterized by vasculopathy, inflammation, and fibrosis, and carries one of the worst prognoses if patients also develop pulmonary arterial hypertension (PAH). Although PAH is a known prognosticator, patients with SSc-PAH demonstrate disproportionately high mortality, presumably due to cardiac involvement. In this cross-sectional study, the relationship between cardiac involvement revealed by cardiovascular magnetic resonance (CMR) and systemic microvascular disease severity measured with nailfold capillaromicroscopy (NCM) in patients with SSc-PAH is evaluated and compared with patients with idiopathic PAH (IPAH).

Article Synopsis
  • TTN truncating variants (TTNtv) are the leading genetic cause of dilated cardiomyopathy (DCM), and this study focuses on comparing left atrial (LA) function between patients with and without these variants.
  • Results show that patients with TTNtv have larger LA volumes and reduced LA strain compared to those without genetic variants, indicating more severe LA dysfunction in the TTNtv group.
  • Computational modeling reveals that both left ventricular (LV) and LA dysfunction contribute to the observed differences between the two groups, highlighting complex interactions in heart function for DCM patients.

Aims: Left ventricular (LV) blood flow is determined by intraventricular pressure gradients (IVPG). Changes in blood flow initiate remodelling and precede functional decline. Novel cardiac magnetic resonance (CMR) post-processing LV-IVPG analysis might provide a sensitive marker of LV function in dilated cardiomyopathy (DCM).

Background Late gadolinium enhancement and left ventricular (LV) ejection fraction on cardiovascular magnetic resonance (CMR) are prognostic markers, but their predictive value for incident heart failure or life-threatening arrhythmias in acute myocarditis patients is limited. CMR-derived feature tracking provides a more sensitive analysis of myocardial function and may improve risk stratification in myocarditis. In this study, the prognostic value of LV, right ventricular, and left atrial strain in acute myocarditis patients is evaluated.

Article Synopsis
  • The study aimed to assess the prognostic significance of left atrial (LA) function, specifically LA conduit strain, obtained via cardiac magnetic resonance (CMR) imaging in patients with dilated cardiomyopathy (DCM).
  • Among 488 DCM patients, LA conduit strain along with New York Heart Association (NYHA) functional class and late gadolinium enhancement (LGE) were key predictors of adverse outcomes like sudden death and heart failure hospitalization during a follow-up period of around 6 years.
  • Incorporating LA conduit strain into existing prediction models considerably enhanced their accuracy and effectiveness in forecasting patient outcomes, underscoring its importance in assessing cardiac health in DCM.

Objective: This study aimed to determine whether lower values of feature-tracking cardiovascular magnetic resonance (CMR)-derived left atrial reservoir strain (LARS) and impaired left ventricular (LV) global longitudinal strain (GLS) were associated with the presence of symptoms and long-term prognosis in patients with SSc.

Methods: A total of 100 patients {54 [interquartile range (IQR) 46-64] years, 42% male} with SSc who underwent CMR imaging at two tertiary referral centres were included. All patients underwent analysis of LARS and LV GLS using feature-tracking on CMR and were followed-up for the occurrence of all-cause mortality.

Introduction: Right ventricular (RV) function is of particular importance in systemic sclerosis (SSc), since common SSc complications, such as interstitial lung disease and pulmonary hypertension may affect RV afterload. Cardiovascular magnetic resonance (CMR) is the gold standard for measuring RV function. CMR-derived RV and right atrial (RA) strain is a promising tool to detect subtle changes in RV function, and might have incremental value, however, prognostic data is lacking.

Many patients with COVID-19 experience severe and even fatal disease. Survivors may have long-term health consequences, but data on physical activity and sedentary behaviour are scarce. Therefore, we objectively assessed physical activity (PA) patterns among post-hospitalised patients with COVID-19 and explored associations with patient characteristics, disease severity and cardiac dysfunction.

Article Synopsis
  • Precapillary pulmonary hypertension (pPH) affects the heart's left ventricular (LV) function, but traditional measures like LV ejection fraction (EF) may not reveal subtle dysfunction, necessitating more sensitive assessment techniques.
  • The study compared LA strain and LV intraventricular pressure gradients (IVPG) in 31 pPH patients to 22 healthy volunteers using cardiovascular magnetic resonance (CMR) imaging.
  • Results indicated preserved systolic function in pPH patients, but marked diastolic dysfunction, suggesting that LA strain and IVPG could serve as early indicators of LV dysfunction in these patients.

Introduction: Recent randomised clinical trials showed benefit of non-culprit lesion revascularisation in ST-elevation myocardial infarction (STEMI) patients. However, it remains unclear whether revascularisation should be performed at the index procedure or at a later stage.

Methods And Analysis: The instantaneous wave-free ratio (iFR) Guided Multivessel Revascularisation During Percutaneous Coronary Intervention for Acute Myocardial Infarction trial is a multicentre, randomised controlled prospective open-label trial with blinded evaluation of endpoints.

There is much debate on the use of angiotensin receptor blockers (ARBs) in severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2)-infected patients. Although it has been suggested that ARBs might lead to a higher susceptibility and severity of SARS-CoV-2 infection, experimental data suggest that ARBs may reduce acute lung injury via blocking angiotensin-II-mediated pulmonary permeability, inflammation, and fibrosis. However, despite these hypotheses, specific studies on ARBs in SARS-CoV-2 patients are lacking.

Importance: Bystander cardiopulmonary resuscitation (CPR) is crucial for survival after cardiac arrest but not performed in most cases. New, low-cost, and easily accessible training methods, such as virtual reality (VR), may reach broader target populations, but data on achieved CPR skills are lacking.

Objective: To compare CPR quality between VR and face-to-face CPR training.

Clinical reasoning is a core competence of doctors. Therefore, the assessment of clinical reasoning of undergraduate students is an important part of medical education. Three medical universities in the Netherlands wish to develop a shared question database in order to assess clinical reasoning of undergraduate students in Computer-Based Assessments (CBA).
