Key result
Nuclear exercise stress test with 99mTc-sestamibi revealed ST-segment elevation in the recovery phase, leading to the diagnosis of critical right coronary artery stenosis in an asymptomatic male.

Recovery-phase ST elevation on nuclear stress testing may flag critical stenosis in asymptomatic patients; single case leaves open diagnostic role.
An asymptomatic Caucasian male patient underwent coronary artery disease diagnostics. Standard exercise treadmill test was inconclusive, and Holter ECG study didn't show any significant abnormalities. Considering the high risk of ischemic heart disease nuclear exercise stress test was performed,which revealed ST-segment elevation in the recovery phase of the treadmill exercise test. Single photon emission computed tomography (SPECT/CT) showed myocardial perfusion abnormalities in the inferior and lateral walls of the left ventricle. Furthermore,speckle tracking imaging showed subtle left ventricle dysfunction. Finally critical stenosis in the second segment of right coronary artery was diagnosed in coronary angiography.

Piszczek et al. (2012) conducted a case report in Coronary artery disease (n=1). Nuclear exercise stress test with 99mTc-sestamibi was evaluated. Nuclear exercise stress test with 99mTc-sestamibi revealed ST-segment elevation in the recovery phase, leading to the diagnosis of critical right coronary artery stenosis in an asymptomatic male.
