Overview
Echocardiography is useful to evaluate ventricular function[1] and detect ischemia induced regional wall motion abnormality that occurs at rest, during exercise or with pharmacologic stress test. As a testing modality, two-dimensional echocardiography is often coupled with other testing modalities to detect regional wall motion abnormalities that most frequently occur during induced myocardial ischemia associated with coronary artery disease (CAD). Potential paired testing modalities include: upright treadmill exercise, supine bicycle ergometry, pacing, and pharmacologic stress, particularly with dobutamine. Patients with CAD may respond more adversely to testing modalities than their counterparts. Often, an adverse outcome such as the inability to perform a bicycle ergometry test or exercise treadmill protocol can be characterized as a poor prognostic factor.
Echocardiography
Indications
- Echocardiography is typically useful in patients with murmurs,[2] previous MI[3] history and ECG changes suggestive of hypertrophic cardiomyopathy.[4]
- Regardless of the etiology, diastolic dysfunction has a major impact on the functional status, treatment and prognosis of heart failure.
- There is also an independent association observed between diastolic heart failure and history of ischemic heart disease, further emphasizing the use of echocardiography in patients with signs and symptoms suggestive of heart failure.[5][6]
- Resting echocardiography, doppler imaging and strain rate measurement[7] have improved the ability to identify undetected diastolic dysfunction[8] in chronic stable angina patients without heart failure.
