NCT01521351

Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • 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

    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

    3 years

Secondary Outcomes (1)

  • Relation of other demographic factors with carotid ultrasound and microwave radiometry measurements and outcome

    3 years

Study Arms (4)

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
