Brief Summary:

The purpose of this research study is to determine if carotid artery ultrasound scanning can provide additional information for determining cardiovascular risk in patients.

Patients who agree to participate wil undergo non-invasive carotid intima-media thickness (CIMT) measurement and plaque assessment. Findings of CIMT will be compared to results of patient standard of care stress echocardiogram (SE) and of diastolic function.

We hypothesize tht 1) in patients undergoing SE for inappropriate or uncertain indications, CIMT and plaque assessment will provide useful risk stratification beyond use of traditional risk factors; 2) CIMT findings will correlate with results of SE in terms of exercise capacity and 3) Exercise capacity will correlate with diastolic function.

Official Title: Carotid Intima-Media Thickness and Plaque Assessment Findings in Subjects Undergoing Stress Echocardiography For Risk Stratification
Actual Study Start Date : October 2014
Actual Primary Completion Date : May 2016
Actual Study Completion Date : May 2016

Group/Cohort Intervention/treatment
Stress Echocardiography (SE)
Subjects will undergo CIMT measurements.
Other: Carotid Intima-Media Thickness (CIMT)

Primary Outcome Measures :
  1. % Patients w/ Abnormal IMT vs. % Patients w/ Positive Ischemia on Stress Echocardiogram [ Time Frame: Baseline ]
    We are comparing the % of patients with abnormal IMT defined as presence of plaque (= or >1.5mm) or CIMT >75% percentile for age, race, and gender compared to % of patients with positive ischemia on stress echocardiogram as defined by a new wall motion abnormality on echocardiogram with stress.
