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+.
Article Synopsis
- A study was conducted to evaluate chronic stent recoil in severely calcified coronary lesions treated with thin strut stents after a procedure called rotational atherectomy.
- In a sample of 28 lesions, there was no significant change in minimal stent area over 8 months, although neointimal hyperplasia was noted in patients.
- Stent recoil was observed in 36% of lesions, primarily occurring in areas without calcification, while overall calcium angles showed significant changes, suggesting that although stent recoil can happen, it rarely leads to restenosis.
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.
View Article and Find Full Text PDFBackground: Tolvaptan is a promising drug for the prevention of contrast-induced acute kidney injury (CI-AKI) because it induces aquaresis without adversely affecting renal hemodynamics. CI-AKI is a major cause of acute renal failure associated with increased morbidity and mortality.
Objective: To investigate the effectiveness of different doses of tolvaptan for the prevention of CI-AKI.
Objectives: Using optical coherence tomography (OCT), we evaluated the effect of a cutting balloon (CB) compared with a conventional balloon after rotational atherectomy (RA) and before stenting in severely calcified coronary lesions.
Background: A CB is designed to create discrete incisions to facilitate fracture of severely calcified plaque.
Methods: OCT was performed preintervention (if possible), post-RA, and poststent implantation.
Impact of recanalization of chronic total occlusion on left ventricular electrical remodeling.

Background: Successful percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) is associated with reduction of cardiac mortality, as well as reducing fatal ventricular arrhythmias. The aim of this study was to evaluate the effect of recanalization of CTO on endocardial left ventricular voltages by paired electrophysiological studies.
Methods: Sixteen consecutive patients who underwent PCI for de novo CTO lesions were included.
The relationship between epicardial adipose tissue volume (EATV) and plaque vulnerability in non-culprit coronary lesions is not clearly understood.Fifty-four consecutive patients/158 lesions with suspected coronary artery disease underwent computed tomography (CT) and 40 MHz intravascular ultrasound imaging (iMap-IVUS) in cardiac catheterization. Cross-sectional CT slices were semiautomatically traced from base to apex of the heart.

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.
Article Synopsis
- The study investigates the impact of high-dose loop diuretics at discharge on cardiovascular mortality in Japanese heart failure patients.
- Patients who received high doses of diuretics (≥40 mg/day of furosemide) had significantly higher rates of cardiovascular and all-cause mortality compared to those on lower doses.
- The findings suggest that high-dose loop diuretics are a predictor of worse outcomes in heart failure patients, indicating that a dose of 40 mg furosemide daily should be considered high in this population.
Background: Recently several studies showed that worsening renal function (WRF) during hospitalization might be a strong independent predictor of poor prognosis in decompensated heart failure (HF) patients. However, these studies had a relatively short follow-up duration and their data were limited to in-hospital outcomes. Our purpose was to assess the relationship between WRF and long-term cardiovascular mortality in HF patients.

Methods: We prospectively enrolled 40 patients hospitalized for HF.
