BACKGROUND There is a paucity of randomized trials regarding diagnostic testing in women with suspected coronary artery disease (CAD). It remains unclear whether the addition of myocardial perfusion imaging (MPI) to the standard ECG exercise treadmill test (ETT) provides incremental information to improve clinical decision making in women with suspected CAD. METHODS AND RESULTS We randomized ...
OBJECTIVES Due to the frequent use of coronary angiography the awareness of Takotsubo stress cardiomyopathy (TSC) has increased although the exact pathophysiology of TSC is still largely unknown. Our objective was to investigate the effects of mental stress on myocardial function, heart rate variability (HRV) and salivary cortisol (SC) in TSC patients. DESIGN This study is a case-control stud...
Background—There is a paucity of randomized trials regarding diagnostic testing in women with suspected coronary artery disease (CAD). It remains unclear whether the addition of myocardial perfusion imaging (MPI) to the standard ECG exercise treadmill test (ETT) provides incremental information to improve clinical decision making in women with suspected CAD. Methods and Results—We randomized sy...
BACKGROUND Cardiovascular magnetic resonance (CMR) myocardial perfusion imaging (MPI) is a state-of-the-art noninvasive modality for detection of myocardial ischemia and coronary artery disease. Magnetic resonance coronary angiography (MRCA) allows visualization of the coronary tree, but its incremental value as part of a CMR protocol including MPI and late gadolinium enhancement (LGE) is not w...
Dexmedetomidine is a commonly used sedative and adjuvant agent to general anesthesia. The present was designed to evaluate the effects of dexmedetomidine on myocardial function by using tissue Doppler echocardiography during general anesthesia in patients with diastolic dysfunction. Forty patients undergoing orthostatic surgery with ejection fraction preserved diastolic dysfunction grade 2 or 3...
BACKGROUND Fibroblast growth factor-23 (FGF-23) is a phosphorus-regulating substance. Circulating FGF-23 levels increase markedly in dialysis patients and are independently associated with increased risk of mortality. Given the fact that cardiovascular disease is the leading cause of death in dialysis patients, the aim of this study was to test if elevated FGF-23 levels might be associated with...
