Insights

The neutrophil to lymphocyte ratio (NLR) and Global Registry of Acute Coronary Events (GRACE) score can predict in-hospital death in elderly patients with acute myocardial infarction (AMI). Elevated NLR is a potential predictor for mortality in this patient group.

Area of Science:

  • Cardiology
  • Inflammation Research
  • Geriatric Medicine

Background:

  • Coronary artery disease (CAD) is a complex condition where inflammation is a key factor.
  • Predicting in-hospital mortality in elderly patients with acute myocardial infarction (AMI) is crucial for effective management.
  • Inflammatory markers like the neutrophil-to-lymphocyte ratio (NLR) and risk scores such as the Global Registry of Acute Coronary Events (GRACE) score warrant investigation for prognostic value.

Purpose of the Study:

  • To investigate the association between inflammatory markers (NLR, GRACE score) and in-hospital mortality in elderly AMI patients.
  • To explore the prognostic value of NLR and GRACE score for predicting outcomes in this demographic.

Main Methods:

  • Retrospective analysis of 1000 consecutive CAD patients, divided into elderly (≥60 years) and younger (<60 years) groups.
  • Assessment of laboratory and clinical characteristics, including calculation of NLR and GRACE score.
  • Comparison of NLR and GRACE scores between different patient subgroups (e.g., myocardial infarction types, risk strata) and survival outcomes.

Main Results:

  • Elderly patients with myocardial infarction (NSTEMI/STEMI) showed significantly higher NLR compared to those with unstable or stable angina.
  • NLR was significantly elevated in elderly AMI patients versus younger counterparts and higher in high-risk GRACE score groups.
  • Both elevated NLR and GRACE score were significantly associated with in-hospital death; ROC analysis identified optimal cut-off values for predicting mortality.

Conclusions:

  • An elevated neutrophil-to-lymphocyte ratio (NLR) is a potential predictor of in-hospital mortality in elderly patients experiencing acute myocardial infarction.
  • The NLR and GRACE score demonstrate prognostic value for identifying elderly AMI patients at higher risk of in-hospital death.

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals-I

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Poisson's Ratio01:23

Poisson's Ratio

Poisson's ratio is a material property that indicates their stress response. It explains the connection between the elongation or compression a material undergoes in the direction of an applied force and the contraction or expansion it experiences perpendicular to that force. When a slender bar is loaded axially, it stretches in the direction of the force and contracts laterally. Poisson's ratio is the negative ratio of this lateral contraction to the axial elongation. The negative sign...

Odds Ratio01:09

Odds Ratio

The odds ratio (OR) is a statistical measure used extensively in epidemiology and research to quantify the strength of association between exposure and outcome across different groups. Unlike relative risk, which compares the probabilities of an event occurring, the odds ratio compares the odds of an event occurring in the exposed group to the odds of it occurring in the unexposed group. The odds, in this context, are calculated as the probability of the event happening divided by the...

Hazard Ratio01:12

Hazard Ratio

The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.  
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...
