Left atrial systolic function in acute coronary syndromes

Left atrial relaxation and left ventricular systolic function determine left atrial reservoir function.

BACKGROUND Determinants of left atrial (LA) reservoir function and its influence on left ventricular (LV) function have not been quantified. METHODS AND RESULTS In an open-pericardium, paced (70 and 90 bpm) pig model of LV regional ischemia (left anterior descending coronary constriction), with high-fidelity LV, LA, and RV pressure recordings, we obtained the LA area with 2D automated border ...

Prognostic value of C-Reactive Protein in Acute Coronary Syndromes

Introduction: Coronary artery disease (CAD) is among the most common, serious, chronic and life- threatening illnesses in the world. CAD represents a spectrum of conditions, with acute myocardial infarction at one end of it and silent ischemia at the other. There is growing evidence on importance of prognosis of C- reactive protein (CPR) in unstable angina and this protein is a maker of an adve...

Left atrial and left atrial appendage systolic function in patients with post-myocardial distal blocks

INTRODUCTION The study aimed to evaluate function of the left atrium (LA) and of the left atrial appendage (LAA) after myocardial infarction (MI) complicated by intracardiac conduction disturbances. MATERIAL AND METHODS The study comprised 59 patients with persistent post-myocardial distal blocks, who were allocated to one of the three following subgroups: study group I - 20 patients with lef...

Unprotected left main revascularization in patients with acute coronary syndromes.

AIMS In acute coronary syndromes (ACS), the optimal revascularization strategy for unprotected left main coronary disease (ULMCD) has been little studied. The objectives of the present study were to describe the practice of ULMCD revascularization in ACS patients and its evolution over an 8-year period, analyse the prognosis of this population and determine the effect of revascularization on ou...
