How do quantitative coronary CT angiography and pericoronary adipose tissue characteristics relate to dynamic myocardial perfusion SPECT in patients with acute myocardial infarction?
Pericoronary adipose tissue volume is inversely associated with myocardial blood flow and coronary flow reserve, suggesting a link between PCAT characteristics and microvascular dysfunction in acute myocardial infarction.
: Patients with MICAD demonstrated a greater extent of atherosclerosis and larger PCAT volume compared with MINOCA. Moreover, PCAT volume demonstrated inverse associations with MBF and CFR, indicating a potential link between PCAT characteristics and microvascular dysfunction.
