Article Synopsis
  • Guideline-directed medical therapy (GDMT) is crucial for improving outcomes in patients with critical limb ischemia (CLI), especially those with chronic kidney disease (CKD).
  • A study analyzed the prescription rates of GDMT for CLI patients undergoing peripheral vascular interventions, highlighting that those with CKD received lower rates of GDMT both before and after the procedure.
  • There was notable variability in GDMT delivery across different medical sites, indicating a need for better management strategies for patients, particularly those at higher risk for poor outcomes.

Article Synopsis
  • * Methods: Researchers reviewed 135 procedures performed on 116 patients, collecting data on demographics, symptoms, and various outcomes, including procedural success and complications related to the device and procedure.
  • * Results: The study found an overall procedural success rate of 87.4% with no device-related complications; however, some minor complications like access site hematoma (5.2%) and very low rates of major bleeding (0.7%) were reported, alongside 30-day adverse

Background: Critical limb ischemia (CLI) morbidity and mortality rates have historically been disproportionately higher than for other atherosclerotic diseases, however, recent trends have not been reported. In patients admitted with CLI, we aimed to examine trends in in-hospital mortality, major amputations, length of stay, and cost of hospitalizations overall and stratified by type of revascularization procedures.

Methods: Using 2011 to 2017 National Inpatient Sample data, we identified CLI-related admissions based on codes.

Objective: Patients with chronic kidney disease (CKD) have a greater risk of peripheral arterial disease (PAD). Although individual studies have documented an association between CKD and/or end-stage renal disease (ESRD) and adverse outcomes in patients undergoing PAD interventions in an era of technological advances in peripheral revascularization, the magnitude of the effect size is unknown. Therefore, we performed a meta-analysis to compare the outcomes of PAD interventions for patients with CKD/ESRD with those patients with normal renal function, stratified by intervention type (endovascular vs surgical), reflecting contemporary practice.

  • There is limited research on the outcomes of patients with peripheral arterial disease (PAD) who also have chronic kidney disease (CKD) or end-stage renal disease (ESRD), prompting a systematic review and meta-analysis to fill this gap.
  • The analysis included 16 studies with over 44,000 patients and found that those with CKD/ESRD faced significantly higher rates of major amputations and early mortality compared to those without these conditions, especially when the intervention was for critical limb ischemia (CLI).
  • The study highlights the need for randomized trials to better understand the risks and outcomes of PAD interventions in patients with CKD/ESRD, given the concerning data on their elevated risks.

Introduction: The femoropopliteal (FP) segment is a common site of involvement in peripheral arterial disease (PAD) and endovascular therapy has been shown to be safe and effective in the treatment of FP disease. Self-expanding nitinol stents are now frequently used for the treatment of FP disease but in-stent restenosis (ISR) remains a major issue that can lead to recurrence of symptoms requiring repeated revascularizations. Compared to plain old balloon angioplasty (POBA), drug-coated balloons (DCBs) have shown promising results with reduction of ISR rates and target lesion revascularization (TLR).

Objectives: We sought to compare outcomes between intravascular ultrasound- (IVUS) versus angiography (AO)-guided peripheral vascular interventions (PVIs). Introduction: Intravascular ultrasound facilitates plaque visualization and angioplasty during PVIs for peripheral arterial disease. It is unclear whether IVUS may improve the durability of PVIs and lead to improved clinical outcomes.

Atrial fibrillation (AF) is the most common arrhythmia worldwide, leading to an extensive public health and economic burden. The increasing incidence and prevalence of AF is due to the advancing age of the population, structural heart disease, hypertension, diabetes, and thyroid disease. The majority of costs associated with AF have been attributed to the cost of hospitalization.

Since the introduction of new antiplatelet and anticoagulant agents in the last decade, large-scale data studying gastrointestinal bleeding (GIB) in patients undergoing percutaneous coronary intervention (PCI) are lacking. Using the Nationwide Inpatient Sample, we identified all hospitalizations from 2006 to 2012 that required PCI. Temporal trends in the incidence and multivariate predictors of GIB associated with PCI were analyzed.

Introduction: Anti-arrhythmic medications (AAMs) are known to increase cardiac mortality significantly due to their pro-arrhythmic effects. However, the effect of AAMs on non-cardiac mortality has not been evaluated.

Methods: Trials published in English language journals from 1990 to 2015 were thoroughly retrieved by searching websites such as PubMed, Medline, Cochrane Library, and Google Scholar.

Background: The newer second-generation cryoballoons (CB-2 or Arc-Adv-CB) have been shown to achieve significantly lower temperature and faster pulmonary vein isolation (PVI) time in comparison with first-generation cryoballoons (CB-1 or Arc-CB). To test the premise that second-generation cryoballoons can improve clinical outcomes in comparison to first-generation cryoballoons in terms of safety and efficacy, we pooled data for systemic review and meta-analyses from all available literature comparing their clinical performance.

Methods: The Cochrane Library, PubMed, Google Scholar, and studies presented at various meetings were searched for any published literature comparing safety and efficacy of the second-generation cryoballoons (Arctic Front Advance cryoballoons) with first-generation cryoballoons (Arctic Front Cryoballoons).

Atrial fibrillation (AF) is the most common type of sustained arrhythmia, which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden.

Atrial fibrillation (AF) is the most prevalent arrhythmia worldwide and the most common arrhythmia leading to hospitalization. Due to a substantial increase in incidence and prevalence of AF over the past few decades, it attributes to an extensive economic and public health burden. The increasing number of hospitalizations, aging population, anticoagulation management, and increasing trend for disposition to a skilled facility are drivers of the increasing cost associated with AF.
