A diagnostic process combining train electrocardiography with nuclear imaging, this evaluation is used to judge coronary artery illness. Through the examination, the person walks on a treadmill whereas coronary heart exercise is monitored with an electrocardiogram. A radioactive tracer, generally technetium-99m sestamibi (Cardiolite), is injected intravenously close to peak train. Subsequent imaging of the guts reveals areas of enough and insufficient blood stream.
This built-in strategy enhances diagnostic accuracy in comparison with train electrocardiography alone. The perfusion photographs determine myocardial ischemia, typically earlier than it turns into evident throughout customary stress testing. This functionality permits clinicians to detect blockages in coronary arteries and assess the extent of injury to the guts muscle, offering helpful data for therapy choices. The event of those mixed strategies considerably improved non-invasive cardiac analysis.
