Radionuclide techniques for the assessment of myocardial viability.
O ver the past decade the number of patients presenting with heart failure has increased exponentially. It has been estimated that 4.7 million patients in the USA have chronic heart failure, with 400 000 new cases per year, resulting in one million hospitalisations. The diagnostic and therapeutic costs involved with heart failure are estimated to be more than $11 billion per year. Gheorghiade a...
متن کاملStunning, hibernation, and assessment of myocardial viability.
The last 3 decades have witnessed an unprecedented improvement in the outcome of patients with acute coronary syndromes. The widespread use of thrombolytic therapy and percutaneous coronary interventions, in association with increasingly potent antithrombotic agents, has contributed to significant reductions in mortality and morbidity in these patients. Although overall survival has improved, a...

Correspondence to: Don Poldermans, MD, PhD, Thoraxcentre, Department of Cardiology, Erasmus Medical Centre Rotterdam, Dr. Molewaterplein 40, 3015 GD Rotterdam, The Netherlands; [email protected] _________________________ C oronary artery disease is the most common cause of congestive heart failure. More than 70% of the patients with heart failure symptoms have underlying coronary diseas...
متن کاملPathophysiology of myocardial hibernation. Implications for the use of dobutamine echocardiography to identify myocardial viability.
Since the pioneering works of Tennant and Wiggers, it has been known that total ischaemia leads to a prompt cessation of contraction and eventually results in the appearance of cell damage and irreversible myocardial necrosis. Accordingly, in the minds of many cardiologists, the discovery of an abnormal regional contraction in a patient with coronary artery disease had long been equated with th...
متن کاملComparison between left ventricular electromechanical mapping and radionuclide perfusion imaging for detection of myocardial viability.
BACKGROUND A novel 3-dimensional left ventricular (LV) mapping system uses low-intensity magnetic field energy to determine the location of sensor-tipped electrode catheters within the LV. Using this system, we sought to distinguish between infarcted, ischemic, and normal myocardium by comparing LV electromechanical mapping data with myocardial perfusion imaging studies. METHODS AND RESULTS U...
