Insights
Coronary artery stent diameter is linked to patient age, gender, diabetes mellitus, and left ventricular ejection fraction. These factors independently influence the choice of stent size in patients with severe coronary artery disease.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Biomedical Engineering
Background:
- Percutaneous coronary intervention (PCI) is a common treatment for severe coronary artery stenosis.
- Stent diameter selection is crucial for optimal outcomes but its determinants are not fully understood.
- Factors like patient demographics and cardiac function may influence stent size choice.
Purpose of the Study:
- To investigate the relationship between coronary artery stent diameter and patient characteristics.
- To identify predictors of stent diameter in patients undergoing PCI for severe coronary lesions.
Main Methods:
- Analysis of 2256 patients undergoing PCI for severe coronary artery stenosis.
- Categorization of stent diameters into two groups: 2.5-2.75 mm and ≥3 mm.
- Statistical analysis including univariate and multivariate models to assess predictor variables.
Main Results:
- Stent diameter was not significantly affected by the type of PCI procedure (primary, early invasive, elective).
- Age, gender, history of diabetes mellitus (DM), and left ventricular ejection fraction (LVEF) were significantly associated with stent diameter.
- Multivariate analysis confirmed these associations, highlighting key patient-related factors.
Conclusions:
- Coronary artery stent diameter is independently associated with patient gender, age, history of DM, and moderate-to-severe systolic left ventricular dysfunction.
- These findings can inform personalized stent selection strategies in interventional cardiology.
- Understanding these relationships may contribute to improved procedural success and patient outcomes.
Objective:
This study aimed to determine the relationship between the diameter of coronary artery stents and age, gender, diabetes mellitus (DM), left ventricular ejection fraction (LVEF), renal dysfunction, and the clinical presentation of myocardial ischemia in the cohort of patients with implanted stents in coronary arteries with severe stenotic lesions.
Methods:
This study included 2256 patients (mean age, 59.3±10.9 years; men, 62%) who underwent percutaneous coronary intervention (PCI). The clinical status of the patients at presentation was subcategorized as follows: ST-segment elevation myocardial infarction, non-ST segment elevation myocardial infarction, unstable angina pectoris, and stable angina pectoris. The diameters, without any type or brand differentiation, were divided into two groups as follows: Group I, which included 2.5- and 2.75-mm-diameter stents, and Group II, which included ≥3-mm-diameter stents.
Results:
The type of procedure, including primary PCI, early invasive strategy, and elective stenting, was not found to be a significant factor affecting the diameter of coronary artery stents. Univariate and multivariate analyses revealed a relationship between the diameter of coronary artery stents and age, gender, DM, and LVEF.
Conclusion:
This study demonstrated that the diameter of coronary artery stents was independently associated with gender, age, a history of DM, and moderate-to-severe systolic left ventricular dysfunction.
