BACKGROUND The interplay between the novel adipokine retinol-binding protein-4 (RBP4) and coronary artery disease (CAD) is still obscure. We investigated the relationship between RBP4 levels and the presence and severity of angiographically proven CAD and determined its possible role in acute myocardial infarction (AMI). METHODS 305 individuals with(More)
BACKGROUND Adjunctive interventions protect from reperfusion injury during primary percutaneous coronary intervention (PCI), but it is not known whether they are also protective during elective PCI. We sought to assess the efficacy of staccato reperfusion (SR) during PCI. METHODS Thirty seven patients with recent acute coronary syndrome and target lesions(More)
Transcatheter aortic valve implantation (TAVI) has nowadays replaced open heart surgery as an alternative therapeutic tool in selected patients. Thirty-five percent of patients with severe degenerative aortic valve stenosis (AS) remain untreated because of the existing comorbidities that increase their perioperative risk. TAVI is a relatively new technique(More)
Large coronary arteriovenous fistulas (CAVF) cause severe symptoms and their repair involves the serious challenge of occluding the fistula while simultaneously preserving normal coronary flow. We present a case of a giant CAVF involving the right and left coronary arteries in a symptomatic adult patient and its successful surgical repair.
The effect of β-adrenergic blockade on coronary collateral blood flow has not been clarified. We examined the acute effects of β-adrenergic blockade on coronary collateral blood flow. Fifteen patients (Part A) with stable angina were studied while undergoing coronary angioplasty. According to the protocol, all patients underwent a minimum of three balloon(More)
Aims: To test the hypothesis that ketanserin augments coronary collateral blood flow and decreases myocardial ischemia during balloon angioplasty. Methods and Results: Forty-four patients with single vessel disease and stable angina were studied. Collateral flow was determined during balloon inflations, based on the distal velocity time integral (13(More)
OBJECTIVE To investigate the effects of staccato reperfusion (SR) during percutaneous coronary intervention (PCI) on myocardial microcirculatory function as assessed by myocardial contrast echocardiography. SETTING Tertiary centre. METHODS Thirty-nine patients were randomised to SR (n=20) or abrupt reperfusion (AR, n=19) within 48 h of an acute coronary(More)
Left ventricle (LV) apical ballooning syndrome (ABS) is a recently established reversible cardiomyopathy (CM) that presents as acute coronary syndrome (ACS) with ST segment elevation and specific echocardiographic (Echo) findings in the absence of significant coronary artery disease. Synonyms of ABS include "stress-induced CM" and "Takotsubo CM", terms that(More)
We investigated the effects of coronary rotational atherectomy (PTCRA) on plasma levels of endothelin-1 (ET-1), atrial natriuretic peptide (ANP), and cyclic adenosine monophosphate (cAMP). We studied 14 patients undergoing PTCRA and compared them with 14 patients undergoing plain balloon angioplasty. Blood samples were taken from the femoral vein at(More)
