Can nuclear imaging methods improve sudden cardiac death risk stratification in cardiovascular patients?
Can nuclear imaging methods improve sudden cardiac death risk stratification in cardiovascular patients?
Nuclear imaging offers a potentially more reliable alternative or adjunct to left ventricular ejection fraction for sudden cardiac death risk stratification by visualizing underlying pathophysiological processes.
Nuclear imaging may refine SCD risk stratification beyond LVEF; leaves open whether it improves outcomes or changes practice.
Sudden cardiac death is a cause of fatal outcomes in large proportion of cardiovascular patients. Left ventricle ejection fraction at the moment is the main criteria for sudden cardiac death risk stratification, however the parameter is not enough reliable. Nuclear imaging methods make it to visualize finer pathophysiological processes representing the probability of the life threatening ventricular arrhythmias development. The review is focused on recent data on nuclear imaging for cellular perfusion assessment, transient ischemia, vitality of myocardium and myocardial blood flow, metabolic disorders and sympathetic innervation.
