Comparison of Cardiac Diagnostic Tests: Stress Test, CT Angio, Nuclear Scan & Angiography

Various cardiac tests assess coronary anatomy and myocardial perfusion. Dr. Aramesh selects the most appropriate test based on clinical presentation and risk factors.

1. Treadmill Exercise Stress Test

Monitors ECG and BP changes under progressive exercise to detect stress-induced ischemia.

2. Coronary CT Angiography (CCTA)

Non-invasive 3D imaging of coronary arteries using IV contrast to detect calcification and luminal stenosis.

3. Nuclear Myocardial Perfusion SPECT Scan

Evaluates regional myocardial blood supply during rest and pharmacological or exercise stress.

4. Invasive Coronary Angiography

Gold-standard catheterization procedure permitting direct diagnostic visualization and therapeutic stenting.
