Serum levels of the soluble urokinase-type plasminogen activator receptor (suPAR) reflect immune and inflammatory activation, and are shown to be associated with cardiovascular outcomes. We herein investigated the potential association between suPAR and left ventricular diastolic dysfunction among patients with preserved left ventricular ejection fraction (LVEF) and sinus rhythm. Among 291 patients who had sinus rhythm and an LVEF of ae50% enrolled in the study, 26 (8.9%) were considered to have diastolic dysfunction. Patients with diastolic dysfunction had lower estimated glomerular filtration rate (eGFR), and higher systolic blood pressure (BPs), BNP, C-reactive protein, and suPAR than those without diastolic dysfunction. As compared with the first suPAR quartile, the fourth suPAR quartile was significantly associated with both diastolic dysfunction with an odds ratio of 8.95 [95% confidence interval (CI), 1.04-77.0, P < 0.05] after adjusting for sex, age, BPs log(eGFR), CRP, and diuretic use. On the other hand, receiver-operating characteristic curve (ROC) analysis showed that addition of log(suPAR) to the combination of age, sex, and log(eGFR), CRP, and diuretic use did not significantly improve the prediction of diastolic dysfunction. Among cardiac patients with preserved LVEF, serum suPAR was associated with diastolic dysfunction independent of confounding factors by logistic regression analysis. However, according to the ROC analysis, the utility of suPAR as a biomarker for diastolic dysfunction may be limited from a clinical point of view.

Mean serum uric acid (SUA) levels are higher in men than women. In addition, recent studies have suggested that the SUA threshold at which the cardiovascular risk might increase may vary between women and men. In the current retrospective study, by analyzing the data from 219 female and 519 male patients who were free from uric acid-lowering medication, we investigated whether SUA is associated with left ventricular mass index (LVMI), left ventricular ejection fraction (LVEF), and plasma levels of B-type natriuretic peptide (BNP) independent of confounding factors, such as serum calcium, inorganic phosphate, and fibroblast growth factor 23 (FGF23), in a gender-specific manner.

The role of pentraxin 3 (PTX3) has been implicated in the process of plaque vulnerability. However, few studies have addressed the direct relationship between plaque morphology and plasma PTX3. We evaluated the relationship between coronary vulnerable plaque, assessed by optical coherence tomography (OCT), and plasma PTX3 in patients with coronary artery disease (CAD).

A 52-year-old man was admitted to our hospital due to shortness of breath that developed one week after the diagnosis of influenza infection. He had a past history of myocarditis associated with influenza B infection 16 years before the current admission. The patient's left ventricular function showed diffuse hypokinesis with a left ventricular ejection fraction of 28%. Due to the progression of heart failure, the infusion of catecholamines and insertion of an intra-aortic balloon pump were required. The patient was discharged uneventfully on the 23rd hospital day. A significant increase in the serum antibody titer against influenza A virus subtype H3N2 led to a diagnosis of recurrent fulminant influenza myocarditis.

Immunoglobulin G4 (IgG4)-related disease is an emerging new clinicopathological disorder that is characterized by elevation of serum IgG4 levels and histological findings of IgG4-positive plasmacytic infiltration. IgG4-related disease may appear synchronously or metachronously in a wide variety of organs. The current patient was found to have pericardial effusion and retroperitoneal fibrosis. He was subsequently diagnosed with coronary artery stenosis. F-18-FDG positron emission tomography showed enhanced FDG uptake in lymph nodes as well as pericardial and peri-aortic tissue. Histopathology of the mediastinal lymph node showed the infiltration of numerous IgG4-positive cells, leading to the diagnosis of IgG4-related lymphadenopathy with pericardial and periarterial involvement.
