A 70-year-old woman suffered from bilateral lacrimal gland enlargement from 2 years ago (figure 1). Geranium-enhanced MRI disclosed diffuse enlargement of bilateral eyelids indicating IgG4-related disease (IgG4RD), especially Mikulicz’s disease. Laboratory tests showed elevation of serum IgG4 concentration and histopathological findings of the lacrimal glands showed IgG4-positive cell infiltration and obliterated veins by inflammatory cells, which consist of lymphocytes and plasma cells (obliterative phlebitis).

Background: High coronary thrombus burden has been associated with unfavorable outcomes in patients with ST-segment elevation myocardial infarction (STEMI), the optimal management of which has not yet been established. Methods: We assessed the adjunctive catheter-directed thrombolysis (CDT) during primary percutaneous coronary intervention (PCI) in patients with STEMI and high thrombus burden. CDT was defined as intracoronary infusion of tissue plasminogen activator (t-PA; monteplase). Results: Among the 1849 consecutive patients with STEMI, 263 had high thrombus burden. Moreover, 41 patients received t-PA (CDT group), whereas 222 did not receive it (non-CDT group). No significant differences in bleeding complications and in-hospital and long-term mortalities were observed (9.8% vs. 7.2%, p = 0.53; 7.3% vs. 2.3%, p = 0.11; and 12.6% vs. 17.5%, p = 0.84, CDT vs. non-CDT). In patients who underwent antecedent aspiration thrombectomy during PCI (75.6% CDT group and 87.4% non-CDT group), thrombolysis in myocardial infarction grade 2 or 3 flow rate after thrombectomy was significantly lower in the CDT group than in the non-CDT group (32.2% vs. 61.0%, p < 0.01). However, the final rates improved without significant difference (90.3% vs. 97.4%, p = 0.14). Conclusions: Adjunctive CDT appears to be tolerated and feasible for high thrombus burden. Particularly, it may be an option in cases with failed aspiration thrombectomy.

Patients with hypertrophic cardiomyopathy (HCM) may progress to the dilated phase (DHCM). This study aimed to identify the predictive factors for DHCM progression, including left ventricular (LV) ejection fraction (LVEF < 50%) or decreased LV contraction (LVEF < 60%). The study included 291 patients enrolled in our hospital’s HCM registry who were grouped based on their poststudy LVEF (LVEF of ≥60%, 50–59%, and <50%). Predictive factors of an LVEF of <50% or <60% were determined. Further, the effects of percutaneous transluminal septal myocardial ablation (PTSMA) on long-term systolic LV function and DHCM development were investigated. LVEF was ≥60%, 50–59%, and <50% in 239, 33, and 19 patients, respectively, during the follow-up period (mean: 64.9 months). Multivariate analyses indicated baseline atrial fibrillation (AF), nonsustained ventricular tachycardia (NSVT), and left ventricular diameter at end-systole (LVDs) as significant predictors of DHCM. Using a scoring method based on AF, NSVT, and LVDs, patients with 2 and 3 points had a significantly higher risk of developing DHCM. PTSMA in 78 HCM patients demonstrated no significant effect on long-term LVEF changes or DHCM development. We concluded that AF, NSVT, and LVDs are significant predictors of DHCM development. However, a validation study with a larger population is required.

BACKGROUND: The absence of practice standards in vasoactive agent usage for acute decompensated heart failure has resulted in significant treatment variability across hospitals, potentially affecting patient outcomes. This study aimed to assess temporal trends and institutional differences in vasodilator and inotrope/vasopressor utilization among patients with acute decompensated heart failure, considering their clinical phenotypes. METHODS: Data were extracted from a government-funded multicenter registry covering the Tokyo metropolitan area, comprising consecutive patients hospitalized in intensive/cardiovascular care units with a primary diagnosis of acute decompensated heart failure between January 2013 and December 2021. Clinical phenotypes, that is, pulmonary congestion or tissue hypoperfusion, were defined through a comprehensive assessment of clinical signs and symptoms, vital signs, and laboratory findings. We assessed the frequency and temporal trends in phenotype-based drug utilization of vasoactive agents and investigated institutional characteristics associated with adopting the phenotype-based approach using generalized linear mixed-effects models, with random intercepts to account for hospital-level variability. RESULTS: Among 37 293 patients (median age, 80 years; 43.7% female), 88.6% and 21.2% had pulmonary congestion and tissue hypoperfusion status, respectively. Throughout the study period, both overall and phenotype-based vasodilator utilizations showed significant declines, with overall usage dropping from 61.4% in 2013 to 48.6% in 2021 ( P _trend <0.001). Conversely, no temporal changes were observed in overall inotrope/vasopressor utilization from 24.6% in 2013 to 25.8% in 2021 or the proportion of phenotype-based utilization. Notably, there was considerable variability in phenotype-based drug utilization among hospitals, with a median ranging from 48.3% to 77.8%. In multivariable-adjusted models, a higher number of board-certified cardiologists were significantly associated with lower rates of phenotype-based vasodilator utilization and reduced inappropriate inotrope/vasopressor utilization, while tertiary care hospitals were linked to more appropriate inotrope/vasopressor utilization. CONCLUSIONS: Substantial variability existed among hospitals in phenotype-based drug utilization of vasoactive agents for patients with acute decompensated heart failure, highlighting the need for standardized treatment protocols.
