Aims:We have previously shown that 2-dimentional strain is not a useful tool for ruling out acute coronary syndrome (ACS) in the emergency department (ED). The aim of the present study was to determine whether in patients with suspected ACS, global longitudinal strain (GLS), measured in the ED using 2-dimensional strain imaging, can predict long-term outcome.Methods: Long-term (median 7.7 years [IQR 6.7-8.2]) major adverse cardiac events (MACE; cardiac death, ACS, revascularization, hospitalization for heart failure, or atrial fibrillation) and all-cause mortality data were available in 525/605 patients (87%) enrolled in the Two-Dimensional Strain for Diagnosing Chest Pain in the Emergency Room (2DSPER) study. The study prospectively enrolled patients presenting to the ED with chest pain and suspected ACS but without a diagnostic ECG or elevated troponin. GLS was computed using echocardiograms performed within 24 hours of chest pain. MACE of patients with worse GLS (>median GLS) were compared to patients with better GLS (≤ median GLS).Results: Median GLS was −18.7%. MACE occurred in 47/261 (18%) of patients with worse GLS as compared with 45/264 (17%) with better GLS, adjusted HR 0.87 (95% CI 0.57-1.33, P = .57). There was no significant difference in all-cause mortality or individual endpoints between groups. GLS did not predict MACE even in patients with optimal 2-dimensional image quality (n = 164, adjusted HR=1.51, 95% CI 0.76-3.0). Conclusions:Global longitudinal strain did not predict long-term outcome in patients presenting to the ED with chest pain and suspected ACS, supporting our findings in the 2DSPER study.

Background We have previously reported an increased risk for non-hematological malignancies in young patients with moderate or severe aortic stenosis (AS). These findings were the result of a post-hoc analysis from a large echocardiography database and needed verification. Our aim was to determine, using a different study population, whether young patients with AS are at increased risk for cancer. Methods A large echocardiographic database was used to identify patients (age ≥ 20 years) with moderate or severe AS (study group) and patients without aortic stenosis (comparative group). The new occurrence of non-hematological malignancies was determined after the index date (first echo with moderate or severe AS or first recorded echo in the control group). Results The final study group included 7013 patients with AS and 98,884 without AS. During a median follow-up of 6.9 years (3.0–11.1) there were 10,705 new cases of non-hematological cancer. The crude incidence rate of cancer was higher in AS compared to non-AS patients (22.3 vs. 13.7 per 1000 patient-year, crude HR 1.58 (95%CI 1.46–1.71). After adjustment for relevant covariates, there was no difference between groups (HR 0.93, 95% CI 0.86–1.01). Only patients in the lowest age quartile (20–49.7 years), had an increased adjusted risk of cancer (HR 1.91, 95%CI 1.08–3.39). The HR for the risk of cancer associated with AS was inversely proportional to age (P < 0.001 for the interaction between AS and age). Conclusions Young patients with moderate or severe AS may have an increased risk for cancer. Cancer surveillance should be considered for young patients with AS.

Despite the increasing recognition of cardiac involvement in systemic sarcoidosis, the diagnosis of cardiac sarcoidosis (CS) remains challenging. Our aim is to present a comprehensive, retrospective case series of CS patients, focusing on the current diagnostic guidelines and management of this life-threatening condition. In our case series, patient data were collected retrospectively, including hospital admission records and rheumatology and cardiology clinic visit notes, detailing demographic, clinical, laboratory, pathology, and imaging studies, as well as cardiac devices and prescribed medications. Cases were divided into definite and probable CS based on the 2014 Heart Rhythm Society guidelines as well as presumed CS based on imaging criteria and clinical findings. Overall, 19 CS patients were included, 17 of whom were diagnosed with probable or presumed CS based on cardiac magnetic resonance imaging (CMR) and/or cardiac positron emission tomography using 18F-Fluorodeoxyglucose (PET-FDG) without supporting endomyocardial biopsy (EMB). The majority of CS patients were male (53%), with a mean age of 52.9 ± 11.8, with CS being the initial manifestation of sarcoidosis in 63% of cases. Most patients presented with high-grade AVB (63%), followed by heart failure (42%) and ventricular tachyarrhythmia (VT) (26%). This case series highlights the significance of utilizing updated diagnostic criteria relying on CMR and PET-FDG given that cardiac involvement can be the initial manifestation of systemic sarcoidosis, requiring prompt diagnosis and treatment to prevent morbidity and mortality.
