Transient reduction of regional myocardial perfusion during angina at rest with ST-segment depression or normalization of negative T waves.
Previous studies have shown localized thallium-201 (20'Tl) defects during resting anginal episodes with ST-segment elevation. In this report, findings of 2oiTl during spontaneous angina in 14 patients with ST-segment depression and seven with normalization of negative T waves are reported. One millicurie of 20'T1 was injected i.v. during the ischemic episode and scintigrams were taken within 5-...
متن کاملHemoglobin A1c testing alone does not sufficiently identify patients with prediabetes.
Whether hemoglobin A(1c) (HbA(1c)) values are suitable for diagnosing diabetes has been debated. We sought to assess the prevalence of elevated HbA(1c) levels in a prediabetes patient population. Oral glucose tolerance tests and HbA(1c) levels were analyzed for patients entering a diabetes prevention program between January 1, 2007, and September 13, 2009. We calculated the percentage of patien...

15 صفحه اولAbnormal myocardial perfusion pattern in convalescent Kawasaki Disease patients assessed by stress perfusion cardiovascular magnetic resonance
Background Kawasaki Disease is a generalised systemic vasculitis involving blood vessels throughout the body, although the coronary arteries virtually always are involved. Previous evidence from echocardiographic, Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) studies of myocardial blood flow and flow reserve in KD patients revealed reduced hyperemic f...
متن کاملMechanism of reversible (99m)Tc-sestamibi perfusion defects during pharmacologically induced vasodilatation.
Reversible perfusion defects on (99m)Tc-sestamibi imaging during hyperemia are thought to occur due to myocardial blood flow (MBF) "mismatch" between regions with and without stenosis. We have recently shown that myocardial blood volume (MBV) distal to a stenosis decreases during hyperemia, resulting in a reversible perfusion defect on myocardial contrast echocardiography (MCE). In this study, ...
