Objectives: Little is known about the risk profile and in-hospital prognosis of elderly patients presenting for ST-elevation myocardial infarction (STEMI) in Tunisia. We sought to determine in-hospital prognosis of elderly patients with STEMI in a Tunisian center.
Methods: The study was carried out on a retrospective registry enrolling 1403 patients presenting with STEMI in a Tunisian center between January 1998 and January 2013. Patients ≥75 years old were considered elderly. Risk factors and in-hospital prognosis were compared between elderly and younger patients, and then predictive factors of in-hospital death were determined in elderly patients.
Results: Out of the overall population, 211 (15%) were part of the elderly group. Compared to younger patients, elderly patients were more likely to have arterial hypertension but less likely to be smokers and obese. Thrombolysis was significantly less utilized in the elderly group (22.3% vs. 36.6% in the younger group, p<0.001), whereas the use primary percutaneous coronary intervention was comparable between the two sub-groups (24.2% vs. 28.8%, p=0.17). The incidence of in-hospital complications was higher in the elderly group, and so was the in-hospital mortality rate (14.2% vs. 8.1%, p=0.005). Heart failure on-admission, renal failure on-admission, and inotropic agents use were independently associated to in-hospital death in the elderly group.
Conclusions: In the Tunisian context, elderly patients presenting with STEMI have higher prevalence of risk factors and a worse in-hospital course in comparison to younger patients. Clinical presentation on-admission has a strong impact on in-hospital prognosis.

Objective: To evaluate the clinical efficacy and safety of noninvasive positive pressure ventilation combined with pressure support ventilation (NPPV-PSV) in the treatment of chronic heart failure (CHF) through a meta-analysis.
Methods: A systematic search was conducted using PubMed, Embase, Web of Science, Cochrane Library, CNKI and Wanfang databases to find randomized controlled trials and cohort studies on NPPV-PSV treatment for CHF. The period of search was set from inception until 2024.

Background: SET domain-containing protein 4 (SETD4) is a histone methyltransferase that has been shown to modulate cell proliferation, differentiation, and inflammatory responses by regulating histone H4 trimethylation (H4K20me3). Previous reports have demonstrated its function in the quiescence of cancer stem cells as well as drug resistance in several cancers. A limited number of systematic studies have examined SETD4's role in the tumor microenvironment, pathogenesis, prognosis, and therapeutic response.

Background: Acute type A aortic dissection (AAD) and acute type A intramural hematoma (AIMH) are life-threatening conditions with high mortality rates, and prognostic indicators are critical for guiding urgent treatment decisions. We assessed the prognostic significance of admission D-dimer levels in patients with AAD and AIMH.
Methods And Results: The prospective, multicenter, observational study in China recruited participants from 2013 to 2019.
Background: The purpose of this study was to investigate whether circulating pyruvate kinase M2 (PK-M2) levels are elevated in the peripheral blood and to assess their association with diagnosis and prognosis in patients with heart failure (HF).
Methods And Results: We conducted a prospective investigation involving 222 patients with HF and 103 control subjects, measuring PK-M2 concentrations using ELISA. The primary outcome, assessed over a median follow-up of 2 years (interquartile range: 776 to 926 days), was the time to the first occurrence of either rehospitalization for worsening HF or cardiovascular death.
