Left Ventricular Perfusion and Innervation in Paced Patients

چکیده
C ardiac pacing constitutes an efficient treatment for bradyarrhythmias, while it has also been used recently in the therapy of dilated and hypertrophic cardiomyopathy. At the dawn of the pacing era, our interest was focused on ensuring stable, permanent pacing. Now, that our knowledge of the pathophysiology of the paced beat has deepened, our interest in the identification of more “physiological” pacing sites and explanation of the effect of pacing on the treatment of heart failure and hypertrophic obstructive cardiomyopathy (HOCM) is renewed. Thus, myocardial innervation and perfusion along with their acute and long-term alterations have been the objective of a number of studies, that used different pacing sites.

Dipyridamole stress and rest gated 99mTc-sestamibi myocardial perfusion SPECT: left ventricular function indices and myocardial perfusion findings
Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. Methods: 297 consecutive patients were studie...

Introduction: Left ventricular ejection fraction (LVEF) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. LVEF is not improved in all patients after coronary artery bypass grafting (CABG). This study aimed to assess the possibility of prediction of LVEF changes after CABG using myocardial perfusion gated signle photon emission compu...

Introduction: We aimed to assess whether the vasodilator effect of oral dipyridamole on the left ventricular systolic function in patients with suspected CAD is different from that of intravenous (IV) dipyridamole using Tc-99m MIBI myocardial perfusion gated SPECT. Methods: Eighty-nine patients (17 M / 72 W; 61 ± 10 years) were enrolled in this study. The patients underwent a dipyridamole stre...

Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...

Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography.
