Intervention / Treatment |
---|---|
Experimental: Definity
All patients will undergo a gray scale baseline unenhanced imaging session (apical 2- or 4 chamber view), as well as a DEFINITY (Perflutren Lipid Microsphere Injectable Suspension)-enhanced rest and a DEFINITY enhanced exercise or dobutamine stress echocardiography imaging session.
The unenhanced and DEFINITY-enhanced rest and stress echocardiography imaging sessions will be performed on the same day.
For the DEFINITY-enhanced imaging sessions all patients will receive diluted DEFINITY intravenously (IV).
Diluted DEFINITY will be prepared by mixing 1 mL of activated DEFINITY® with 9 mL of normal saline in a 10 mL syringe.

Number of Participants With Abnormal Contrast Stress Echocardiography and With Future Major Adverse Cardiac Events (MACE) at 2 and 5 Years Follow-Up
Time Frame: 2 year and 5 year follow up
|
Peri- or post-menopausal female participants with an intermediate pre-test likelihood of coronary artery disease (CAD) received a Definity contrast-enhanced stress echocardiography study at baseline using either treadmill exercise or dobutamine stresss. Images were evaluated for wall motion abnormalities. The results were compared to patient history on 2-year and 5-year follow up to identify the potential of stress echocardiography for predicting those at higher risk of experiencing future cardiac events. Major adverse cardiac events (MACE) are defined as

Prognostic value of stress ECG testing for identifying female patients at increased risk of major adverse cardiac events (MACE) at 2-year follow-up Peri- or post-meopausal female subjects with an intermediate pre-test likelihood of coronary artery disease (CAD) received resting ECG at baseline. ECG was evaluated as normal or abnormal. The results were compared to patient history on 2-year follow up to identify the potential for ECG to predict those at higher risk of experiencing future cardiac events.

Change in Brachial Artery Reactivity Was Assessed in in a Subset of Participants With and Without Major Adverse Cardiac Events at 2-year and 5-year Follow-up.
Time Frame: 2 year and 5 year follow up
|
A subset of the study population of peri- or post-meopausal female participants with an intermediate pre-test likelihood of coronary artery disease (CAD) was assessed for brachial artery reactivity at baseline. Brachial diameter was assessed using ultrasound and a pressure cuff both before and after administration of sublingual nitroglycerin. The results were compared to patient history on 2-year and 5-year follow up to identify the potential for brachial artery reactivity to predict those at higher risk of experiencing future cardiac events.The brachial artery reactivity was summarized using number of subjects with and without MACE on follow-up. Major adverse cardiac events (MACE) are defined as

Mean Baseline Calcium Score of Participants With and Without Major Cardiac Events at 2-year Follow up.
Time Frame: 2 year follow up
|
Coronary artery calcium scoring assesses calcification of the coronary arteries using electron-beam computed tomography (EBCT). It is a sum of lesion scores of area and density above a threshold density. There is no intrinsic upper limit to the calcium score but values above 1000 may not be measurable. A subset of peri- or post-meopausal females with an intermediate pre-test likelihood of coronary artery disease (CAD) received resting EBCT at baseline. Images were evaluated for calcium score and results compared to patient history on 2-year follow up, Mean calcium score with confidence interval was summarized for subjects with and without major cardiac events (MACE) at 2-year follow up. Calcium score for general population: Score Description Relative Risk 0 No evidence of CAD 0 1-112 Average Risk of CAD 1.9 100-400 Moderate risk of CAD 4.3 400-999 High risk of CAD 7.2 1000 Very high risk of CAD 10.8 |

The Presence of Wall Motion Abnormalities on Definity Stress Echocardiography Assessed for Participants With Both Normal and Abnormal Angiography
Time Frame: 60 days
|
In the sub-set of efficacy-evaluable participants who underwent clinically indicated coronary angiography, the accuracy of exercise echocardiography vs. angiography was determined for the detection of CAD.
Positive angiography was defined as any stenosis greater than or equal to 50% in any vessel.
Wall motion index change indicating abnormal motion was defined as greater than or equal to 13% in 2 or more segments.
Angiography was required to have taken place within 60 days following stress echocardiography.
