Insights

Elevated serum Kidney Injury Molecule-1 (KIM-1) levels and lower heart rate (HR) are linked to coronary no-reflow phenomenon (CNP) in ST-segment elevation myocardial infarction (STEMI) patients. CNP also increases stroke risk.

Area of Science:

  • Cardiology
  • Biomarkers
  • Acute Myocardial Infarction

Background:

  • Coronary no-reflow phenomenon (CNP) is a complication of percutaneous coronary intervention.
  • CNP is associated with adverse cardiovascular outcomes, including major adverse cardiovascular events (MACE).

Purpose of the Study:

  • To investigate the association between serum Kidney Injury Molecule-1 (KIM-1) levels and CNP in patients with acute ST-segment elevation myocardial infarction (STEMI).

Main Methods:

  • A total of 160 STEMI patients were divided into a reflow group (n=140) and a no-reflow group (n=20).
  • Serum KIM-1 levels, body mass index (BMI), heart rate (HR), and EuroSCORE II were measured.
  • Patients were followed for one year to assess outcomes, including stroke incidence.

Main Results:

  • CNP occurred in 12.50% of STEMI patients.
  • Serum KIM-1 levels were significantly higher in the no-reflow group compared to the reflow group (p<0.001).
  • Lower HR (p<0.001), higher BMI (p=0.047), and higher EuroSCORE II (p=0.016) were also observed in the no-reflow group.
  • Baseline KIM-1 levels and lower HR were identified as independent predictors of CNP (p=0.002 and p<0.001, respectively).
  • The incidence of stroke was significantly higher in the no-reflow group (15% vs. 2.90%, p=0.013).

Conclusions:

  • Baseline serum KIM-1 concentrations and lower heart rate are independently associated with CNP in STEMI patients.
  • CNP in STEMI patients is linked to an increased incidence of stroke during a one-year follow-up.

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
