NICE has recently issued guidance for patients with chest pain of recent onset suggesting exercise stress testing is of little value. Instead, an assessment is made of the nature of the pain then three risk factors in addition to age and gender are used to calculate a risk score. This allocates patients to a range of sophisticated tests including cardiac computed tomography, myocardial perfusio...

A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...

We present a female patient with atypical chest pain who was referred to our department for ischemia evaluation. Tc-MIBI myocardial perfusion scan with dipyridamole stress was performed. Sub-diaphragmatic activity in the hepatic tissue and then in the bowel loops caused severe overlap on the inferior wall even on consecutive delayed images. Dipyridamole stress was repeated for the patient with ...

A 74-year-old man was referred to the Cardiology clinic with a 3-week history of exertional chest tightness. These episodes lasted a few seconds without any limitation to activity. The gentleman is an ex-smoker and a hypertensive on treatment. The results of the clinical examination and ECG were unremarkable. An exercise tolerance test was found to be negative, albeit at a subtarget heart rate....

BACKGROUND The incremental prognostic value of stress single photon emission computed tomography (SPECT) for the prediction of cardiac death as an individual end point and the implications for risk stratification are undefined. METHODS AND RESULTS We identified 5183 consecutive patients who underwent stress/rest SPECT and were followed up for the occurrence of cardiac death or myocardial infa...

introduction: this study evaluated the diagnostic value of the dipyridamole induced electrocardiuogram (ecg) cahnges, comparing with myocardial perfusion imaging. materials and methods: 222 patinets were studied with dipyridamole infusion (based on ecg criteria) as well as dipyridamole-myocardial perfusion imaging (mpi). results: abnormal dipyridamole test and abnormal mpi were noted in 11% and...
