The prescription of aspirin (acetylsalicylic acid (ASA)) to patients with a history of hypersensitivity to this drug could prove harmful. The aim of the study was to assess the antiplatelet activity and safety of a combined antiplatelet treatment with indobufen and clopidogrel in acute coronary syndrome (ACS) patients with hypersensitivity to aspirin,(More)
The assessment of left ventricular shape changes during cardiac revolution may be a new step in clinical cardiology to ease early diagnosis and treatment. To quantify these changes, only point registration was adopted and neither Generalized Procrustes Analysis nor Principal Component Analysis were applied as we did previously to study a group of healthy(More)
BACKGROUND AND OBJECTIVE An elevated heart rate (HR) is an independent risk factor for mortality and morbidity in patients with acute heart failure (HF). The purpose of this study was to evaluate the impact of ivabradine, a selective HR-lowering agent, in patients with cardiogenic shock (CS) complicating ST-elevation acute myocardial infarction (AMI).

In this paper we use the 7 mm and 1.3 mm light curves obtained during the 2003.5 low excitation phase of the η Carinae system to constrain the possible parameters of the binary orbit. To do that we assumed that the mm wave emission is produced in a dense disk surrounding the binary system; during the low excitation phase, which occurs close to periastron,(More)

In this paper we present observations of η Carinae in the 1.3 mm and 7 mm radio continuum, during the 2003.5 low excitation phase. The expected minimum in the light curves was confirmed at both wavelengths and was probably due to a decrease in the number of UV photons available to ionize the gas surrounding the binary system. At 7 mm a very well defined(More)
Blazars are characterized by the existence of brightness variability in all observed wavelengths occurring in very short time scales. The origin of the extreme activity is probably related to a relativistic jet that lies very close to the line of sight. Since the radio to X-rays emission in blazars can be associated with synchrotron radiation, multiband(More)
Levosimendan increases the sensitivity of the heart to calcium and consequently exerts positive inotropic effects. Levosimendan is indicated in acutely decompensated severe congestive heart failure. We report that levosimendan infusion may induce myocardial ischemia in patients with acute heart failure.
Intensive monitoring of low-extinction windows towards the galactic bulge has provided in the last years valuable information for studies about the dynamics, kinematics and formation history of this part of the galaxy, mainly by characterizing the bulge stellar populations (Paczyński, 1996). Since 1997, we have been conducting an intensive(More)
We present results of a microvariability polarization study in the violently variable quasar 3C279. We have resolved the polarization curves in the V band for this object down to timescales of minutes. We found two main components in the evolution of the degree of linear polarization, one consisting of a flicker with timescales of several tens of minutes(More)
We present optical light curves for the period 1996-2000, of two of the brightest known EGRET BL Lac objects: PKS 2005-489 and PKS 2155-304, the latter also one of the few known TeV sources. For both objects, quiescent epochs of low level of variability were followed by active periods, without any indication of periodicity. In PKS 2005-489, several(More)
