Stress MPI, coronary CTA, and multimodality for subsequent risk analysis

Effect of Stress on Coronary Risk Factors

In India, a survey indicates the prevalence of 30 times increase in hypertension among urban dwellers, compared with 10 times in rural inhabitants.1 Urbanization together with a change in life style, diet, and job stress, has been attributed in causing hypertension.Stress can cause hypertension by elevating the blood pressure (BP) and by stimulating the nervous system leading to the production ...

Dose optimization in coronary CTA.

The annual number of computed tomography (CT) procedures in the U.S. has increased 20-fold (from 3 to 60 million) between 1985 and 2005 (1), and as a result, the average (i.e., per capita) annual background dose in the U.S. has nearly doubled from 3.0 to 5.6 mSv (2). This has precipitated increasing societal concern over the potential public health impact—an increased risk of cancer—associated ...

Coronary CTA: Pattern of Disease

Management of Coronary Artery Calcium and Coronary CTA Findings

Coronary artery calcium (CAC) testing and coronary computed tomography angiography (CTA) have significant data supporting their ability to identify coronary artery disease (CAD) and classify patient risk for atherosclerotic cardiovascular disease (ASCVD). Evidence regarding CAC use for screening has established an excellent prognosis in patients with no detectable CAC, and the ability to risk r...

A systematic approach for analysis, interpretation, and reporting of coronary CTA studies

Over the past years, the number of coronary computed tomography angiography (CTA) studies performed worldwide has been steadily increasing. Performing a coronary CTA study with appropriate protocols tailored to the individual patient and clinical question is mandatory to obtain an image quality that is diagnostic for the study purpose. This process can be considered the primary mainstay of each...
