Background. Worldwide, coronary artery disease (CAD) is a leading cause of mortality and morbidity remains to be top health priority in many countries. A non-invasive imaging modality for diagnosis CAD such as single photon emission computed tomography-myocardial perfusion (SPECT-MPI) usually requested by cardiologists it displays radiotracer distribution the heart reflecting myocardial perfusi...

BACKGROUND Although high exercise tolerance is associated with an excellent prognosis, the significance of abnormal myocardial perfusion imaging (MPI) in patients with high exercise tolerance has not been established. This study retrospectively compares the utility of MPI and exercise ECG (EECG) in these patients. METHODS AND RESULTS Of 388 consecutive patients who underwent exercise MPI and ...

The study aims to discuss the relationship and difference between myocardial perfusion imaging (MPI) using SPECT and CT coronary angiography (CTCA) for diagnosis of coronary artery disease (CAD). Five hundred and four cases undergoing MPI and CTCA were comparatively analyzed, including fifty six patients undergoing invasive coronary angiography in the same period. Among patients with negative M...

Abstract Introduction Current cardiac PET and computed tomography imaging allows the simultaneous acquisition of anatomic physiological data for patients suspected CAD. Purpose We aimed to evaluate incremental prognostic value coronary artery calcium (CAC) score flow reserve (CFR) in with disease (CAD) undergoing positron emission (PET) myocardial perfusion (MPI). Methods included consecutive w...

statement of the problem periodontitis is a common infectious disease that can be affected by different factors.periodontal conditions can be influenced by systemic diseases and they also can act as risk factors for some systemic diseases. several studies have been carried out on the relationship between cardiovascular disease and periodontal disease. purpose the purpose of our study was to eva...

BACKGROUND Nuclear myocardial perfusion imaging (MPI) involves the use of radiotracers to generate scintigraphic images of the myocardium. It is the best validated and most standardised of all cardiac imaging modalities, demonstrating regional perfusion ventricular wall motion and accurately calculating reproducible left ventricular ejection fraction. Physiological or pharmacological stress can...
