Background

Nonsteroidal immunosuppressive therapy is a potential therapeutic strategy for cardiac sarcoidosis. However, it is not recommended as an established treatment option. This study aimed to demonstrate the clinical outcomes of patients with cardiac sarcoidosis using nonsteroidal immunosuppressants through the ILLUstration of the Management and PrognosIs of JapaNese PATiEnts with Cardiac Sarcoidosis multicenter retrospective registry.

Methods

From a cohort of 512 patients, 426 who received corticosteroid therapy and 26 who received other immunosuppressive therapy were included for analysis. Clinical outcomes included all-cause death, fatal ventricular arrhythmic events (FVAE), and worsening heart failure with hospitalization.

Results

Nonsteroidal immunosuppressants were used for retained fluorodeoxyglucose uptake in the heart (n = 14), corticosteroid side effects (n = 7), ventricular arrhythmia (n = 4), complete atrioventricular block (n = 2), worsened extracardiac sarcoidosis (n = 2), and other reasons (n = 2). They comprised of methotrexate (n = 20), cyclosporine (n = 2), cyclophosphamide (n = 2), and azathioprine (n = 3). After the addition of a nonsteroidal immunosuppressant, corticosteroids were reduced in 14 of 26 patients (5 [5–17] mg), although no patient discontinued corticosteroids. Of the 14 patients, decreased fluorodeoxyglucose uptake was observed in seven at follow-up. Clinical outcomes were observed in 11 patients (42.3 %). Detected events included all-cause death in five patients (19.2 %), FVAE in four (15.4 %), and worsening heart failure with hospitalization in five (19.2 %), with some overlap.

Conclusions

Nonsteroidal immunosuppressive therapy may be a possible treatment option for patients who are not stabilized with corticosteroids alone or develop corticosteroid side effects.

Background

This study investigated excess risk in patients with heart failure with reduced left ventricular ejection fraction (HFrEF) with or without elevated levels of NT-proBNP (N-terminal pro-brain natriuretic peptide).

Methods

Patients with HFrEF from the NorthStar cohort (n = 1120) were matched on age, sex, and presence of AF (atrial fibrillation/flutter) to five controls without HFrEF from The Danish National Patient Registries. Patients were compared with controls before and after stratification according to baseline NT-proBNP levels, with cutoffs defined as </≥ 600 pg/ml in patients with sinus rhythm and </≥ 900 pg/ml in patients with AF. The primary composite endpoint was a 7-year risk of cardiovascular death or HF admission.

Results

In the HFrEF cohort, 704 patients had high NT-proBNP (median age, 73; mean left ventricular ejection fraction (LVEF), 33%). 416 patients had low NT-proBNP (median age, 65; LVEF, 30%). Patients from both groups were in NYHA class I-III. The primary endpoint occurred in 531 patients (75.4%) with HFrEF and elevated NT-proBNP, and 748 controls (21.3%) (risk difference, 54.2%; 95% confidence interval (CI) 50.7–57.6%). In comparison, it occurred in 199 patients (47.9%) with HFrEF and without elevated NT-proBNP, and 185 controls (8,9%) (risk difference, 38.9%; 95% CI 34.0–43.9%). Risk differences for all secondary endpoints were significant, except for overall mortality in the low NT-proBNP group (risk difference, 3.8%; 95% CI, −0.4–8.0%).

Conclusion

This study identified a significant excess risk in patients with HFrEF across various endpoints, which persisted after stratification into high and low levels of NT-proBNP.

Background

In Japan, the number of very elderly individuals with heart failure (HF) is on the rise. One indicator of HF stage progression is a decrease in exercise tolerance (ET). While peak oxygen uptake (peak VO₂) determined by cardiopulmonary exercise testing (CPX) is the gold standard for ET assessment, the wide-scale applicability of CPX is constrained owing to expensive equipment and challenges in this population. The 30-second chair stand test (CS30), a simple and quick alternative, is widely used among community-dwelling elderly individuals. The objective of this study was to investigate whether CS30 is a predictor of ET in elderly individuals with stage A/B HF.

Methods

Of 748 outpatients aged 75 years and over who visited our center between March 2021 and December 2022, 493 patients (296 males and 197 females) were included in this study. CS30 was measured using a seat height of 40 cm, and peak VO₂ was assessed using CPX.

Results

The findings showed a statistically significant positive association between CS30 and peak VO₂ for both males and females (males: β = 0.255, 95 % CI = 0.102–0.407; females: β = 0.282, 95 % CI = 0.043–0.521). Receiver operating characteristic (ROC) analyses showed moderate accuracy of CS30 in predicting low ET in both sexes (males AUC = 0.740, 95 % CI = 0.640–0.841, p < 0.001; females AUC = 0.725, 95 % CI = 0.644–0.807, p < 0.001). The cut-off values of CS30 were established as 18 times for males and 16 times for females.

Conclusions

CS30 is a potentially convenient method for estimating current ET in older adults, providing a feasible alternative to CPX.

Background

Inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), is a prevalent condition associated with chronic noninfectious inflammation of the gastrointestinal tract. It has been hypothesized that chronic inflammation can predispose patients to atrial fibrillation (AF), however, no clear evidence exists to support this.

Methods

A systematic literature search was conducted using major databases aimed at studies focusing on AF development in patients with IBD. Further subgroup analyses were performed for ulcerative colitis (UC) and crohn’s disease (CD). Risk ratios (RR) with their corresponding 95 % confidence intervals (CI) were pooled using a random-effects model in the Review Manager Software. Statistical significance was set at p < 0.05.

Results

Seven studies with 88,893,407 patients were included (1,002,719 and 87, 890, 688 patients in the IBD and non-IBD groups, respectively). IBD patients were at an increased risk of developing AF [RR: 1.52; 95 % CI: 1.19–1.95; p = 0.0009] compared to the non-IBD group. In subgroup analyses, patients with UC were at an increased risk of developing AF [RR: 1.29; 95 % CI: 1.08–1.53; p = 0.004], as were CD patients [RR: 1.30; 95 % CI: 1.07–1.58; p = 0.008] compared to the non-UC and non-CD groups, respectively.

Conclusion

Patients with IBD are at nearly 1.5 times the risk of developing AF compared to the non-IBD population. Our meta-analysis was limited by heterogeneity among the studies, highlighting the importance of further large-scale prospective studies to establish more robust evidence.

Pulmonary hypertension (PH) is a common and prognostically important complication of mitral regurgitation (MR). Mean pulmonary arterial pressure (mPAP) and pulmonary vascular resistance (PVR) are traditionally used to diagnose PH, however these indices measure static rather than pulsatile load, leading to an incomplete representation of pulmonary vascular load on the right ventricle (RV). Pulmonary arterial compliance (PAC) is one method for quantifying pulsatile load, and is both a stronger predictor of prognosis in left heart failure, as well as a more sensitive measure of early pulmonary vascular dysfunction than PVR. With the expansion of transcatheter mitral and tricuspid valve therapies, there is renewed interest to more accurately define the load imposed by the pulmonary vasculature on the RV, especially in the early phase, prior to the onset of chronic PH. This review discusses the pathophysiology of pH in left heart failure and MR, the utility of PAC as a measure of RV afterload, and its calculation for clinical use and interpretation, underlining the utility of PAC as an adjunct for assessing pulmonary vascular haemodynamics.

In the past few decades, great progress has been made in prenatal diagnosis of congenital heart disease (CHD). Fetal echocardiography is recognized as the main prenatal screening and diagnostic tool that can accurately detect approximately 85 % of fetal cardiac abnormalities. Evaluation of the fetal heart remains a major challenge in prenatal ultrasound screening and diagnosis due to fetal position, involuntary movement, small and complex fetal cardiac anatomy, maternal abdominal wall conditions, and lack of expertise in fetal echocardiography by some physicians engaged in obstetric ultrasound. Artificial intelligence (AI) can automate and standardize the display of each diagnostic section of the fetal heart and thus contribute to accurate diagnosis, which significantly optimizes the clinical application of fetal echocardiography. In this review, we not only clarify the role of AI but also highlight its significance and future solutions in the field of fetal echocardiography.

Introduction

Patients with ST-elevation myocardial infarction (STEMI) and late arrival (>12 h) after symptom onset, are at high risk for mortality and heart failure and represent a challenge for management. We aimed to define patient characteristics, management, and outcome of late-arrival STEMI in Israel over the last 20 years.

Methods

We analyzed data of late-arrival STEMI (12–48 h and > 48 h) from the biennial acute coronary syndrome Israeli Surveys (ACSIS), as well as time-dependent changes [early (2000–2010) Vs. late (2013–2021) period].

Results

Data regarding time from symptom onset to hospital arrival was available in 6,466 STEMI patients. Of these, 9.6 % arrived 12–48 h and 3 % >48 h from symptom onset. Late-arrival patients were more likely to be older women with diabetes and high GRACE score and less likely to have prior myocardial infarction.

In recent years, 95 % of patients arriving 12–48 h and 96 % of those arriving > 48 h had coronary angiography, as opposed to 75 % and 77 % in the early years (p = 0.007). Percutaneous coronary intervention (PCI) increased from 60 % and 55 % respectively to 85 % (p ≤ 0.001).

TIMI-3 flow after primary PCI was 89–92 %, irrespective of arrival time. Late arrival patients (12–48 h but not > 48 h) who had PCI had better adjusted 1-year survival, HR 0.49 (95 %CI 0.29–0.82), p = 0.01.

Conclusions

Late-arrival STEMI patients have higher risk characteristics. Most late-arrival patients undergo coronary angiography and PCI and have TIMI-3 flow after primary PCI. In patients arriving 12–48 h after symptom onset PCI is associated with better survival.

Sepsis-induced cardiomyopathy (SIC) is a common and high-mortality complication among critically ill patients. Uncertainties persist regarding the pathogenesis, pathophysiology, and diagnosis of SIC, underscoring the necessity to investigate potential biological mechanisms. With the rise of omics technologies, leveraging their high throughput and big data advantages, a systems biology perspective is employed to study the biological processes of SIC. This approach aids in gaining a better understanding of the disease’s onset, progression, and outcomes, ultimately providing improved guidance for clinical practices. This review summarizes the currently applied omics technologies, omics studies related to SIC, and relevant omics databases.
