Article Synopsis
- This study investigates the impact of eruptive calcified nodules (CNs) on patient outcomes after percutaneous coronary intervention (PCI) compared to other calcified lesions, finding worse results for those with CNs.
- Researchers analyzed data from 51 patients who underwent PCI for calcified lesions, revealing that 54% of those with eruptive CNs had in-stent CNs at the 8-month follow-up, indicating more neointimal tissue growth.
- The results showed that patients with eruptive CNs experienced a significantly higher target lesion revascularization (TLR) rate both at 1 year (31.3%) and at 5 years (43.8%) compared
Article Synopsis
- A venous aneurysm is a localized dilation in major veins, with popliteal venous aneurysms (PVAs) being rare but serious as they can lead to deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE).
- A 21-year-old woman experienced a transient cardiac-pulmonary arrest due to a massive PTE caused by a thrombus from a right PVA, despite having no history of thrombotic issues.
- After treating her PTE and DVT with thrombolysis, surgical plication of the PVA was performed, and she has not had any recurrence of PTE or DVT in the subsequent two years, suggesting this surgical method may be an effective
This single-centre prospective feasibility study (UMIN000030232) evaluated whether zinc supplementation was safe and effective for improving outcomes among patients with acute myocardial infarction (AMI). Within 24 h after successful primary percutaneous coronary intervention, consenting patients with AMI were randomly assigned 1:1 to receive conventional treatment (conventional treatment group) or conventional treatment plus zinc acetate supplementation (zinc supplementation group). The two groups were compared in terms of major adverse cardiovascular events (MACE), and scar size, which was evaluated using cardiac magnetic resonance imaging (CMR) at 4 weeks after discharge.

We retrospectively enrolled 396 patients with acute decompensated HF. The early drop in SBP was defined as the difference between baseline and SBP measured 24 h after hospitalization.

Methods And Results: We enrolled hospitalized acute HF patients. We divided patients into four groups on the basis of BNP <250 pg/mL (BNP-) or BNP ≥250 pg/mL (BNP+) at discharge and the occurrence of WRF during admission: BNP-/WRF-, BNP-/WRF+, BNP+/WRF-, and BNP+/WRF+.
There are a few studies about the clinical impacts of plasma B-type natriuretic peptide (BNP) at discharge with the occurrence of worsening renal function (WRF) on mortality in patients with heart failure (HF). We divided total 301 patients with acute decompensated HF into four groups by the median value (278.7 pg/mL) of BNP level at discharge and by the occurrence of WRF.

Objective: We assessed the relationships between serum zinc concentration, complications, and prognosis in AMI patients after primary percutaneous coronary intervention.
Methods: We conducted a single-center, prospective, observational study including 50 patients with AMI.
