Birhan; Yilmaz, Ahmet; Yalta, Kenan; Kendirliogiu, Omer; Tandogan, Izzet (HEALTH COMMUNICATIONS INC, 2007)In patients with acute coronary syndrome (ACS), the presence of atrial fibrillation (AF) results in worse inpatient outcomes than in those without AF Two electrocardiographic markers, maximum P wave duration (P-maximum) ... -
Acute Effects of Levosimendan and Dobutamine on QRS Duration in Patients with Heart Failure
Yontar, Osman Can; Yilmaz, Mehmet Birhan; Yalta, Kenan; Erdem, Alim; Tandogan, Izzet (ARQUIVOS BRASILEIROS CARDIOLOGIA, 2010)Background: Levosimendan is a novel inotropic agent that enhances cardiac contractility without increasing cellular calcium intake, so that it is not supposed to cause intracellular calcium overload and related arrhythmias. ... -
Asymptomatic total anomalous pulmonary venous connection with double drainage in a young adult: A case report
Yalta, Kenan; Turgut, Okan Onur; Yilmaz, Ahmet; Yilmaz, Mehmet Birhan; Manduz, Sinasi; Karadas, Filiz; Dogan, Kasim; Tandogan, Izzet (FORUM MULTIMEDIA PUBLISHING, LLC, 2007)Total anomalous pulmonary venous connection is an uncommon congenital anomaly in which all pulmonary venous return drains to the right atrium or one of its tributaries. Survival beyond infancy without surgical palliation ... -
Clinical importance of elevated CK-MB and troponin I levels in congestive heart failure
Yilmaz, Ahmet; Yalta, Kenan; Turgut, Okan Onur; Yilmaz, Mehmet Birhan; Ozyol, Ali; Kendirlioglu, Omer; Karadas, Filiz; Tandogan, Izzet (HEALTH COMMUNICATIONS INC, 2006)Myocyte necrosis has been considered to play a fundamental role in the pathophysiology of congestive heart failure (CHF), which has usually evolved as a consequence of depletion of compensatory mechanisms and contractile ... -
Comparative effects of levosimendan and dobutamine on right ventricular function in patients with biventricular heart failure
Yilmaz, Mehmet Birhan; Yontar, Can; Erdem, Alim; Karadas, Filiz; Yalta, Kenan; Turgut, Okan Onur; Yilmaz, Ahmet; Tandogan, Izzet (SPRINGER, 2009)Severe heart failure represents a major source of morbidity and mortality. Poor right ventricular function is an independent prognostic marker for mortality in patients with chronic heart failure. In this study, levosimendan ... -
Comparison of myocardial performance index versus ratio of isovolumic contraction time/ejection time in left ventricular systolic dysfunction
Yilmaz, Ahmet; Yalta, Kenan; Turgut, Okan Onur; Yilmaz, Mehmet Birhan; Ozyol, Ali; Erdem, Alim; Tandogan, Izzet (SPRINGER, 2007)Myocardial performance index (MPI) has been regarded as an important parameter in the evaluation of ventricular systolic function in congestive heart failure. This study was designed to investigate the relationship between ... -
Coronary collateral circulation: Any effect on P-wave dispersion?
Aslan, Halil; Turgut, Okan; Yalta, Kenan; Yilmaz, Mehmet B.; Ozdemir, Ramazan; Ermis, Necip; Sezgin, Alpay T.; Yetkin, Ertan; Tandogan, Izzet; Yilmaz, Ahmet (SAGE PUBLICATIONS INC, 2008)Coronary collateral circulation determines the severity of ischemic myocardial damage. Increased P-wave dispersion is an independent predictor for atrial fibrillation. Consistent evidence is little about the relation between ... -
Coronary Flow Slows as Renal Function Worsens
Yilmaz, Mehmet Birhan; Yalta, Kenan (WILEY, 2009)Background: Slow coronary flow in patients without obstructive coronary artery disease is an angiographic finding that could easily be detected by thrombolysis in myocardial infarction (TIMI) frame counts. On the other ... -
