Information provided by (Responsible Party):
Konstantinos Toutouzas, University of Athens
  Purpose
A prospective study of 700 patients with coronary artery disease will undergo non invasive evaluation of their carotid arteries by ultrasound and microwave radiometry. The patients will be followed up for 3 years and their outcome regarding the cardiovascular events (death, cardiac events, cerebrovascular events) will be recorded

Condition
Carotid Artery Disease Stroke Myocardial Infarction Angina Pectoris

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective Natural History Study of Carotid Atherosclerosis

Further study details as provided by Konstantinos Toutouzas, University of Athens:

Primary Outcome Measures:
  • To detect if carotid ultrasound and carotid microwave radiometry measurements can predict the incidence of cerebrovascular and cardiovascular events in patients with coronary artery disease [ Time Frame: 3 years ]
    Microwave radiometry is a non invasive and safe technique that measures temperature of the internal tissues by detecting the normal radiation of the tissues in microwave frequencies. The primary outcome of the study is to see if the temperatures measured in the carotid arteries of patients with coronary artery disease can predict their outcome regarding cerebrovascular and cardiovascular events


Secondary Outcome Measures:
  • Relation of other demographic factors with carotid ultrasound and microwave radiometry measurements and outcome [ Time Frame: 3 years ]

Estimated Enrollment: 700
Study Start Date: January 2012
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts
carotid thermal heterogeneity
Patients that have carotid thermal heterogeneity detected by MR
no carotid thermal heterogeneity
Patients that DONT have carotid thermal heterogeneity detected by MR
carotid artery disease
Patients with detected carotid artery disease by ultrasound
no carotid artery disease
Patients with no carotid artery disease detected by ultrasound

Detailed Description:
Carotid artery Thermal heterogeneity recorded by MR will be corelated to cardiovascular events (death, cardiac events, cerebrovascular events) as well as to all demographic (age, sex, hypertension, dyslipidemia, smoking status, etc) factors
