The Number of Patients and Therapeutic Profile of Spinal Stenosis Using Health Insurance Claims in Japan.

Study Design: Population-based retrospective descriptive study.

Objective: To describe the number and therapeutic profile of patients with spinal stenosis at a large-scale community level using health insurance claims data.

Summary Of Background Data: A few reports have documented the prevalence of spinal stenosis, and no report has described the therapeutic profile for spinal stenosis in a population base.

Inelastic vascular prosthesis for proximal aorta increases pulsatile arterial load and causes left ventricular hypertrophy in dogs.

Objectives: Elastic property of the proximal aorta plays an important role in reducing pulsatile load to the ventricle. When a stiff vascular prosthesis is used for the proximal aorta, the pulsatile load increases. We designed this study to elucidate whether the increase in pulsatile load caused left ventricular hypertrophy.
