A diagnostic process combining train electrocardiography with nuclear imaging, this evaluation is used to guage coronary artery illness. Throughout 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 center reveals areas of sufficient and insufficient blood circulate.
This built-in strategy enhances diagnostic accuracy in comparison with train electrocardiography alone. The perfusion photographs establish myocardial ischemia, typically earlier than it turns into evident throughout normal stress testing. This functionality permits clinicians to detect blockages in coronary arteries and assess the extent of harm to the center muscle, offering helpful data for remedy selections. The event of those mixed methods considerably improved non-invasive cardiac analysis.
