Brief Summary:
The purpose of this study is to build upon trials done over 30 years ago, which did not include statins, new antiplatelet agents, and newer antihypertensive medications. Since the landmark trials (NASCET, ECST), there have been new developments in medical stroke prevention, which creates a gap in knowledge. The aim of this study is to evaluate that clinical care with Intensive Medical Therapy (IMT) alone, the one year stroke rate in patients with symptomatic carotid stenosis and low risk clinical features will be <5%.

Condition or disease Intervention/treatment
Carotid Stenosis Ischemic Stroke Transient Ischemic Attack Other: intensive medical therapy

Detailed Description:

This study will only be evaluating clinical care and no interventions will be done specifically for this research.

  • Informed consent from patient or legally authorized representative.
  • Participant survey/questionnaire completion at baseline, 6 and 12 months after enrollment
  • All data collected will be entered into a secure research data registry created for this study.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 114 participants
Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 12 Months
Official Title: Symptomatic Carotid Outcomes Registry With Multi-center Evaluation
Actual Study Start Date : August 1, 2022
Estimated Primary Completion Date : April 2025
Estimated Study Completion Date : October 2025

Group/Cohort Intervention/treatment
Symptomatic carotid stenosis with low risk features
50-99% symptomatic carotid stenosis with low clinical or radiologic risk features (see inclusion criteria) Patients will receive intensive medical therapy, including dual antiplatelet therapy, high potency statins, BP control, and lifestyle modification
Other: intensive medical therapy
Dual antiplatelet therapy, high potency statins, HTN control, lifestyle modification

Primary Outcome Measures :
  1. Ischemic stroke [ Time Frame: within 12 months ]
    ipsilateral to carotid stenosis, with radiologic confirmation

Secondary Outcome Measures :
  1. Myocardial infarction [ Time Frame: within 12 months ]
    ECG will be performed for suspected myocardial infarction and will be diagnosed if appropriate ST changes and confirmation with troponin measurements
