The role of Tc-99m tetrofosmin single-photon emission tomography (SPECT) in the evaluation of myocardial perfusion before and 6 months after successful percutaneous transluminal coronary angioplasty (PTCA) was assessed in 41 consecutive patients (32 men and 9 women). Twenty-five patients had one-vessel disease, 14 had two-vessel disease, and 2 had(More)
AIMS Coronary artery disease (CAD) is a significant cause of morbidity and mortality in modern societies. The association between genetic markers and CAD is still poorly understood. In this study, we evaluated the effect of five genetic variants: Factor V Leiden (FV:c.1691G>A) (rs6025), Factor II prothrombin (FII:c.20210G>A; rs1799963), plasminogen(More)
OBJECTIVE To test the association of early post-stress lung/heart ratio (LHR) of 99mTc tetrofosmin radioactivity with gated-SPECT findings and angiographic results. METHODS We studied 158 consecutive patients, with stress/rest 99mTc tetrofosmin myocardial SPECT and coronary angiography. Rest scans were obtained as gated SPECT and the left ventricular(More)
The aim of this study was to assess the erythropoietic response to hypoxaemia in patients with diffuse idiopathic pulmonary fibrosis (DIPF), and to speculate on the underlying mechanisms. Patients on an established chronic respiratory failure due to DIPF or chronic obstructive pulmonary disease (COPD) were studied. The erythropoietic response to hypoxaemia(More)
Coronary artery disease is associated with multiple genetic and environmental risk factors. In this study, we evaluated the correlation of angiotensin l-converting enzyme (ACE) (I/D) and ApoE gene polymorphisms (E2, E3, E4 and g.-219G/T) with myocardial perfusion. We examined 410 patients using exercise-rest myocardial perfusion single photon emission(More)
AIM Coronary angiography is still the most reliable method for the detection of coronary artery disease. In this study we compared to this method the accuracy of 99mTc-Tetrofosmin myocardial SPECT. METHOD Fifty two patients (38 male and 14 female) were studied with stress-rest 99mTc-Tetrofosmin myocardial SPECT. Two independent observers evaluated the(More)
Stroke syndromes include a variety of syndromes with often overlapping clinical presentations. When ipsilateral hemiplegia is associated with symptoms of a lateral medullary syndrome, it corresponds to the submedullary syndrome of Opalski. A 72-year-old woman presented with sudden onset of headache, gait disturbance, and recurrent vomiting. Her clinical(More)
