This procedure is based on the same ultrasound principles used in transthoracic echocardiography. During the study, special emphasis is placed on the evaluation of the contraction or mobility of each of the segments that make up the different walls of the left ventricle. For the study, images of the heart in a resting state are initially obtained, which will allow their subsequent comparison simultaneously on the same screen with the images obtained during stress, which consists of increasing oxygen consumption by the heart muscle through the use of of certain drugs (pharmacological stress), or by performing physical exercise on the treadmill or stationary bicycle (stress with exercise).
The reason why the drug is used, instead of performing an effort ultrasound on the treadmill or stationary bicycle (Cycloergometer), is due to medical conditions or limitations, which prevent the patient from performing the physical test at that time. .
This test is performed to check the appearance of alterations in the contraction of the heart walls, not present in the study performed at rest, which suggest coronary artery disease.
Currently using the new advanced technology, we can more accurately assess the contraction of the heart muscle at each stage of the study, and in some cases can also make a direct measurement of the flow velocities of the arteries of the heart (coronary arteries) providing a greater diagnostic accuracy when comparing the results with those obtained using traditional echocardiography equipment.
- Arrive 15 minutes before the assigned appointment time.
