Incidence of severe coronary stenosis in asymptomatic patients with peripheral arterial disease scheduled for major vascular surgery
2016
Abstract
Peripheral arterial disease (PAD) has the risk equivalent of coronary heart disease. A total of 50 PAD patients asymptomatic for coronary heart disease were examined using coronary computed tomography angiography (CTA).
A stress myocardial CT perfusion (CTP) test was performed in patients who exhibited coronary stenosis >40 %. According to the combined CT examination (CTA and stress CT perfusion), 36 % of patients exhibited significant coronary stenosis.
Stress-induced hypoperfusion was observed in 95,7 % of severe stenotic lesions. A high prevalence of asymptomatic coronary heart disease was observed in this particular patient group.
High-sensitivity measurements of troponin I correlated with the extent of the coronary stenosis.
