The role of 320 detector row CT perfusion in assessment of myocardial perfusion

Abstract

The estimated incidence of myocardial infarction (MI) is 470000 patients per year in the United States alone (Curtis ,2013). The risk of cardiac complications, such as recurrent acute MI, sudden death, angina pectoris, heart failure, and stroke for those who survive an acute MI is substantial (Adam et al., 2014).

Coronary artery disease (CAD) causes sudden death, nonfatal myocardial infarction, unstable angina (Sparrow et al., 2009). And it is believed to be the underlying cause in approximately two-thirds of patients with chronic heart failure (HF) and low ejection fraction (EF) (Ghostine et al, 2008) where regional myocardial dysfunction leads to global ventricular dysfunction and heart failure over time (Masci et al, 2009).
