Systemic autoimmune diseases are an important cause of pericardial involvement and contribute to up to ∼22% cases of pericarditis with a known aetiology. The underlying mechanism for pericardial involvement varies with each systemic disease and leads to a poor understanding of its management. Multimodality imaging establishes the diagnosis and determines the type and extent of pericardial involvement. In this review, we elaborate upon various pericardial syndromes associated with different systemic autoimmune and autoinflammatory diseases and the multitude of imaging modalities that can be used to further characterize autoimmune pericardial involvement. Lastly, these forms of pericarditis have a greater likelihood of recurrence, and clinicians need to understand their unique treatment approaches to improve patient outcomes.

Heart failure with preserved ejection fraction (HFpEF) affects half of all patients with heart failure. While previously neglected, the right ventricle (RV) has sparked interest in recent years as a means for better understanding this condition and as a potential therapeutic target.Right ventricular dysfunction (RVD) is present in 4%–50% of patients with HFpEF. The RV is intimately connected to the pulmonary circulation, and pulmonary hypertension is commonly implicated in the pathophysiology of RVD. The development of RVD in HFpEF may also be driven by comorbidities, such as chronic obstructive pulmonary disease, obesity, obstructive sleep apnoea and atrial fibrillation. The evaluation of RVD is particularly challenging due to anatomical and structural factors, as well as unique physiological characteristics of this chamber like load and interventricular dependency. Fractional area change, tricuspid annular plane systolic excursion and tricuspid annular systolic velocity are commonly used measurements of RV function. Speckle tracking echocardiography and cardiac magnetic resonance (CMR) are also gaining attention as important tools for the assessment of RV structure, fibre deformation and systolic performance. Further research is needed to confirm the utility and prognostic significance of RV [18F]fluorodeoxyglucose (FDG) positron emission tomography imaging as FDG accumulation is suggested to increase with progressive RVD. Targeted pharmacotherapy with phosphodiesterase inhibitors, guanylate–cyclase stimulators, nitrates and inhaled inorganic nitrites have yet to demonstrate improvement in RVD, compelling the need for evaluation and discovery of novel pharmacological interventions for this entity.

Background Myocardial infarction with non-obstructive coronary arteries is a working diagnosis for several heart disorders. Previous studies on anxiety and depression in patients with myocardial infarction with non-obstructive coronary arteries are lacking. Our aim was to investigate the prevalence of anxiety and depression among patients with myocardial infarction with non-obstructive coronary arteries. Methods We included 99 patients with myocardial infarction with non-obstructive coronary arteries together with age- and sex-matched control groups who completed the Beck Depression Inventory and the Hospital Anxiety and Depression Scale (HADS) 3 months after the acute event. Results Using the Beck Depression Inventory, we found that the prevalence of depression in patients with myocardial infarction with non-obstructive coronary arteries (35%) was higher than in healthy controls (9%; P = .006) and similar to that of patients with coronary heart disease (30%; P = .954). Using the HADS anxiety subscale, we found that the prevalence of anxiety in patients with myocardial infarction with non-obstructive coronary arteries (27%) was higher than in healthy controls (9%; P = .002) and similar to that of patients with coronary heart disease (21%; P = .409). Using the HADS depression subscale, we found that the prevalence of depression in patients with myocardial infarction with non-obstructive coronary arteries (17%) was higher than in healthy controls (4%; P = .003) and similar to that of patients with coronary heart disease (13%; P = .466). Patients with myocardial infarction with non-obstructive coronary arteries and takotsubo syndrome scored higher on the HADS anxiety subscale than those without (P = .028). Conclusions This is the first study on the mental health of patients with myocardial infarction with non-obstructive coronary arteries to show that prevalence rates of anxiety and depression are similar to those in patients with coronary heart disease.
