Clinical outcome and angiographic results with novel polysulfone polymer coating paclitaxel eluting stent in real-world clinical practice: a clinical centre registry.

Background: The Intek-Apollo stent (Switzerland) employs a polysulfone polymer coating which has demonstrated low interaction with blood and high thrombo-resistance. The aim of this study was to assess the clinical and angiographic outcomes after Intek-Apollo stent utilisation in a real-world setting.

Material/methods: A total of 130 patients (77.

Adenosine stress myocardial perfusion tomographic imaging in patients with significant aortic stenosis.

Background: Myocardial perfusion scintigraphy has been used by some investigators for the diagnosis of coronary artery disease (CAD) in patients with mild, moderate, and moderate to severe aortic stenosis, with various results. The aim of this study was to assess the safety and diagnostic accuracy of adenosine stress myocardial perfusion scintigraphy (adenosine single photon emission computed tomography [Ad-SPECT]) for the detection of CAD in patients with significant aortic stenosis.

Methods And Result: The study included 75 patients with significant aortic stenosis (maximal instantaneous aortic valve gradient >80 mm Hg [range, 81-149 mm Hg] and aortic valve area <0.

Detection of coronary artery disease in patients with severe aortic stenosis with noninvasive methods.

Exercise stress ECG testing is not generally recommended in patients with severe aortic stenosis. Analysis of the utility of exercise testing, both with and without the use of myocardial thallium-201 scintigraphy for the diagnosis of coronary artery disease (CAD), yielded low specificity. A noninvasive, safe, and accurate diagnostic modality to ascertain the presence of CAD is not available to date for patients with severe aortic stenosis.

Correlation of clinical and electrocardiography variables with coronary lesions in unstable angina pectoris.

The relation of clinical and electrocardiographic variables to the severity of coronary lesions in unstable angina was studied in 84 men and 8 women, aged thirty-nine to seventy-five, who were subjected to coronary arteriography within two weeks. Eighty-seven patients (94.6%) had significant stenosis (50% of the diameter) of at least one vessel, whereas 5 (5.
