Background: Abdominal aortic calcification (AAC) is a critical indicator of cardiovascular risk, particularly in patients with chronic kidney disease (CKD). Traditional classification systems may underestimate the risk in those with moderate CKD. This study aimed to evaluate the association between CKD risk categories - defined by both estimated glomerular filtration rate (eGFR) and albuminuria - and the prevalence of severe AAC.

Background: Spontaneous coronary artery dissection (SCAD) is a rare and often underdiagnosed cause of acute coronary syndrome (ACS), predominantly affecting younger women without traditional cardiovascular risk factors. The management of SCAD remains a subject of debate, likely secondary to inconclusive evidence. This study aims to compare the clinical outcomes of SCAD patients treated with optimal medical therapy (OMT) versus those who underwent percutaneous coronary intervention (PCI) using a national population-based cohort.

Article Synopsis
  • Spontaneous coronary artery dissection (SCAD) is a condition gaining recognition, especially affecting young, healthy women with acute myocardial infarction (AMI) who often lack traditional risk factors for heart disease.
  • A study analyzed data from the National Inpatient Sample between 2016-2019, finding that of 1.5 million AMI cases in women, over 12,000 were linked to SCAD, revealing similar mortality rates between SCAD and non-SCAD patients.
  • Despite no significant difference in mortality, the incidence of SCAD-related AMI is rising annually, indicating a need for further research on effective treatments for these patients.

Introduction: Peripheral arterial disease (PAD) is a progressive, systemic atherosclerotic disease that is associated with an increased risk of coronary artery disease (CAD), cerebrovascular disease (CVD), and critical limb ischemia (CLI). CLI represents the most severe stage of PAD, characterized by progressive endothelial dysfunction and arterial narrowing. We hypothesized that the incidence of CLI and PAD would increase over the study period and that the rates of in-hospital mortality and major amputations among patients admitted with CLI would rise correspondingly.

Autoimmune Rheumatic Diseases (AIRDs) are associated with increased cardiovascular mortality. However, the post-percutaneous coronary intervention (PCI) outcomes in this population present a research gap, given the limited and discordant findings in existing studies. We conducted a systematic review and meta-analysis to assess the relationship between AIRDs and clinical outcomes after PCI; 9 studies with 7,027,270 patients (126,914 with AIRD, 6,900,356 without AIRD) were included.

Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have become increasingly utilized in patients undergoing percutaneous coronary intervention (PCI). Despite these purported advantages, prior reports regarding the use of IVUS and OCT have indicated that contemporary use of intravascular imaging remains low with significant regional variation. Here, we present the findings of an updated contemporary analysis regarding the use of IVUS/OCT-guided PCI versus angiography-guided PCI in the United States.

Inflammation plays a pivotal role in the pathogenesis of both acute and chronic heart failure. Recent studies showed that the neutrophil-to-lymphocyte ratio (NLR) could be related to adverse outcomes in patients with cardiovascular diseases. We sought to evaluate whether NLR could predict mortality in patients with acute heart failure by means of a meta-analysis.
