Background And Aims: Although the phase angle (PhA), a measure of frailty and sarcopenia, determined by bioelectrical impedance analysis has been reported as a prognostic factor after cardiovascular surgery, few studies have reported the trajectory of the PhA after discharge. In this study, we examined the trajectory of the PhA along with conventional physical function measures and explored the factors associated with recovery for 6 months after hospital discharge in patients who had undergone cardiovascular surgery.

Methods: We included 116 patients who underwent elective cardiovascular surgery and cardiac rehabilitation after discharge.

Existing studies evaluating the comparison of clinical outcome of percutaneous coronary intervention (PCI) for severe calcified coronary lesions are limited, and the clinical outcomes of PCI for different morphologies of calcified lesions are controversial. Overall, consecutive 576 lesions with severe calcification that were treated with PCI from 2010 to 2021 at Nagoya Heart Center were investigated. All lesions were assessed using invasive coronary angiogram (CAG) or computed tomography-CAG at 12 months after DES implantation.

Angiotensin receptor-neprilysin inhibitors (ARNI) are effective against heart failure (HF) with reduced ejection fraction, but hypotension is a significant complication. Predictors of ARNI-associated hypotension remain unclear. This study aimed to determine predictors of hypotension after administering an ARNI to patients with HF accompanied by ARNI.

Article Synopsis
  • The study focused on the prognostic value of phase angle (PhA), a measure of cellular health, in predicting long-term mortality among older patients undergoing cardiovascular surgery.
  • Researchers conducted a retrospective analysis of 858 patients who underwent surgery from October 2016 to March 2021, measuring PhA and various physical function metrics like gait speed and grip strength before the surgeries.
  • Results indicated that higher PhA levels correlated with better physical function and were linked to improved survival rates after surgery, emphasizing the potential use of PhA as a valuable prognostic indicator.

Percutaneous coronary intervention (PCI) requires multiple staff members, including interventional cardiologists, with the physical burden of heavy protective measures to minimize radiation exposure. Here, we aimed to investigate the safety of task sharing with clinical engineers (CEs) working as 1st assistant during ad hoc PCI. We retrospectively included 286 patients who underwent ad hoc PCI following diagnostic catheterization for coronary artery disease between April 2019 and March 2021.

Background: Severely calcified coronary artery stenting remains a challenge due to stent thrombosis, target vessel failure, and higher mortality. Moreover, optimal vessel preparation for calcified plaque with a crack formation pattern has not been established yet. We aimed to identify the effect of crack formation in calcified plaque in the coronary artery on the lumen area after stenting.

Background: There is little evidence on the optimal strategy for bifurcation lesions in CTO.

Methods: We retrospectively reviewed 314 consecutive bifurcation lesions in CTO with SB ≥ 2.

Background: Long-term clinical outcomes beyond 5 years after X-EES implantation remain unclear.

Methods: This retrospective study has collected data from 1184 consecutive patients, corresponding to 1463 lesions, who were treated with X-EES alone in the Nagoya Heart Center between January 2010 and December 2013.

Article Synopsis
  • Obesity is a significant risk factor for coronary artery disease, but its impact on atherosclerosis progression varies by age after percutaneous coronary intervention (PCI).
  • A study divided patients into two groups (middle-aged and elderly) to assess obesity's effect on revascularization for new lesions within two years post-PCI, finding a notable correlation in middle-aged patients.
  • Results suggest obesity may not predict complications in elderly patients, indicating that treatment strategies for preventing revascularization should consider the patient's age.

Recently, Society for Vascular Surgery guideline recommends evaluating anatomic pattern with use of Global Limb Anatomic Staging System (GLASS) in Chronic Limb-Threatening Ischemia (CLTI) patients. The aim of this study is to validate GLASS stage into CLTI patients on hemodialysis (HD) and investigate the impact of GLASS stage to wound healing and amputation-free survival (AFS). Between April 2009 and March 2018, we performed EVT for 154 limbs in CLTI patients on HD.

Purpose: This study aimed to compare the efficacy of ultrasound-guided and angiography-guided intraluminal approach for femoropopliteal (FP) artery occlusive disease.

Methods: A retrospective analysis was performed using the data collected regarding patients that underwent endovascular treatment (EVT) for FP artery occlusive disease between January 2010 and April 2018 at two centers. A total of 221 consecutive de novo lesions were analyzed according to the method of recanalization.

Article Synopsis
  • - The study aimed to evaluate how accurately pre-percutaneous coronary intervention (PCI) predicted nonhyperemic pressure ratios (NHPRs) correspond to actual NHPRs measured after PCI, while also examining the effectiveness of using pre-PCI NHPR assessments for guiding treatment.
  • - Researchers conducted a multicenter trial comparing three NHPR measuring methods—instantaneous wave-free ratio (iFR), resting full-cycle ratio (RFR), and diastolic pressure ratio (dPR)—to see how well they predict functional outcomes post-PCI.
  • - Results showed strong correlations between predicted and actual NHPRs for all three methods, and the NHPR pullback strategy resulted in fewer and shorter treated lesions compared to traditional angiography-guid

Aortoduodenal syndrome is a rare duodenal obstruction caused by an abdominal aortic aneurysm. Current treatment involves open aneurysmal repair according to the theory that this procedure releases the duodenum from mechanical compression. However, the mechanism of duodenal blockage remains unclear and reports of endovascular aneurysm repair (EVAR) for aortoduodenal syndrome are quite rare.

Although stent implantation may be associated with tissue protrusion (TP), especially in patients with acute coronary syndrome (ACS), its long-term clinical outcomes remain unknown. The aim of the current study was to evaluate the long-term clinical outcomes of ACS patients with TP after the implantation of newer-generation drug-eluting stents (DESs). We retrospectively evaluated 366 consecutive ACS patients who underwent primary percutaneous coronary intervention (PCI) with newer-generation DESs.
