Doppler echocardiography is a simple, fast and non-invasive method to identify abnormal regional and global left ventricular function. One could consider this non-invasive method to be the best approach within imaging techniques. Stress echocardiography techniques are used for the diagnosis, risk stratification, prognosis and the study of myocardial viability in the ischemic heart disease. There are many ways to subject the heart to stress for echocardiographic studies. For physically fit patients exercise stress testing using a treadmill or bicycle is unemployed and patients who are unable to exercise undergo pharmacological tests. Although accurate diagnosis and a high prognosis value are achivied with both methods, there are new techniques under study, including the utilization of echocardiographic contrast with microbubbles for endocardial edge evaluation and for myocardial perfusion studies.
