Stress Echo (Stress Echocardiography)
The Stress Echo is a safe and highly accurate imaging test, ideal for diagnosing heart conditions, especially when there is a suspicion of coronary artery blockages or myocardial ischemia.
This test combines:
- High-resolution echocardiography,
- 90% diagnostic accuracy without the use of radiation or contrast agents that could affect kidney function,
- Simplicity and applicability to almost all patients.
How Is Stress Echo Performed?
Stress Echo combines ultrasound (“Triplex”) imaging with cardiac stress, which can be induced in two ways:
- Physical Exercise: Performed on a treadmill or stationary bicycle.
- Pharmacological Stress: Administration of a medication (dobutamine) that mimics the effects of exercise.
The choice of method depends on:
- Equipment availability,
- The physicians’ expertise,
- The patient’s medical history and characteristics.
Enhanced Imaging
For better visualization of the endocardium and increased sensitivity, an intravenous contrast agent (safe and kidney-friendly) may be administered to enhance the imaging quality.
Indications for Stress Echo
Stress Echo is primarily used for:
- Diagnosis of coronary artery disease in patients with or without symptoms and risk factors (e.g., hypercholesterolemia, smoking, hypertension, diabetes).
- Monitoring after acute coronary syndromes (heart attack, angina).
- Assessment of heart function after surgical procedures (bypass surgery, angioplasty).
- Evaluation of myocardial viability following a heart attack.
- Diagnosis of coronary artery disease in heart transplant patients.
- Assessment of valvular heart disease and diastolic dysfunction.
Advantages of Stress Echo
Compared to a standard exercise stress test, Stress Echo offers greater diagnostic accuracy and is ideal for:
- Individuals at high risk for coronary artery disease.
- Women, in whom the standard exercise test may yield false-positive results.
Safety and Side Effects
Stress Echo is a safe test, with rare and mild side effects, including:
- Chest pain,
- Increased or decreased blood pressure,
- Palpitations,
- Nausea, dizziness, or fatigue (mainly with pharmacological stress).
Serious complications, such as a heart attack, are extremely rare. The test is performed under continuous medical supervision in a controlled environment.
Conclusion
Stress Echo is the first-line choice for diagnosing heart conditions, with an expanding range of indications. When performed by specialized cardiologists in modern facilities, it provides accurate results with minimal risk.
