Warranty period of normal CCTA and [15O]H2O PET in chest pain patients

Abstract Background Normal coronary computed tomography angiography (CTA) and positron emission (PET) are associated with an excellent prognosis. Hitherto, data on the warranty period of normal CTA myocardial blood flow (MBF) by PET scarce. Purpose To determine event-free after results. In addition, to whether MBF imaging confers additional prognostic value beyond anatomy in symptomatic patients. Methods Patients suspected but not previously diagnosed artery disease (CAD) who underwent or [15O]H2O were categorized based upon as no CAD, non-obstructive CAD obstructive CAD. A hyperemic <2.3 ml/min/g was considered abnormal indicative for ischemia. cumulative risk below 5% against death infarction (MI) used define period. Results Of 2575 included patients (mean age 61.4±9.9 years, 41% male) 1319 (51.2%) only, 1237 (48.0%) both 19 (0.74%) only. During a median follow-up 7.0 years 163 deaths 68 MIs occurred.
