Abstract

The prevalence of radial access for transradial catheterization remains low in the United States, occurring in only 28% of cases in the National Cardiovascular Data Registry (NCDR) CathPCI. It is unknown whether the low adoption rate has been influenced by patient characteristics or is more operator dependent. In a 10-center study, we compared clinical and demographic characteristics among 323 radial and 1,506 femoral access percutaneous coronary intervention (PCIs) performed by 65 interventionists capable of radial PCI. We created a hierarchical logistic regression model to identify operator and patient characteristics associated with radial PCI and the median rate ratio to quantify the variation across operators. A subset was interviewed to assess health literacy and preferences in shared medical decision making. Radial access was used in 17.7% of patients. Patient factors associated with lower rate of radial PCI were previous PCI (33.4% vs 41.4%, p = 0.008), history of coronary artery bypass graft (8.4% vs 23.0%, p <0.001), and chronic total occlusion PCI (10.2% vs 17.9%, p <0.001). Operator characteristics associated with lower rate of radial PCI are being older, being longer in practice, lower number of publications, and S...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
