Impact of combination evidence-based medical therapy on mortality in patients with acute coronary syndromes.

abstract：:The initial myocardial uptake of thallium-201 depends on myocardial blood flow distribution. The phenomenon of delayed thallium redistribution after transiently or chronically altered myocardial perfusion has been described. The net myocardial accumulation of thallium-201 after injection depends upon the net balance b...
