Repeated stunning precedes myocardial hibernation in progressive multiple coronary artery obstruction.
OBJECTIVE The aim of this study was to characterize a regional myocardial flow-function relationship in collateral dependent myocardium produced by multiple coronary artery obstruction. METHODS Ameroid constrictors were placed around the proximal right (RC) and circumflex (CX) coronary arteries and a silicon tubing cuff around the proximal LAD (left anterior descending artery) (luminal stenos...
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...
متن کاملMyocardial hibernation and stunning: from physiological principles to clinical practice.
In patients with coronary artery disease, one of the most powerful determinants of prognosis is left ventricular function. 2 Thus, if we assume that the prognostic benefit of revascularisation is mediated through an eVect on left ventricular function, two mechanisms might explain this benefit. First, coronary artery bypass surgery or angioplasty could reduce the impact of coronary artery diseas...
متن کاملPostischemic myocardial stunning is superior to transient ischemic dilation for detecting multivessel coronary artery disease.
BACKGROUND Although poststress myocardial stunning is regarded as a marker for severe coronary artery disease (CAD), no study has yet compared the diagnostic value of poststress stunning with transient ischemic dilation (TID) of the left ventricle (LV) for detecting multivessel CAD. METHODS AND RESULTS A total of 271 patients with suspected or known CAD underwent adenosine triphosphate (ATP) ...

chest radiographs must be exceedingly uncommon. Several cases of culture-proved pulmonary tuberculosis with negative chest films have been reported;; however, these cases were detected within a few weeks or months of documented tuberculin conversion, and epidemiologic studies have demonstrated that recovery of viable M tuberculosis is often possible in individuals who have just converted their ...
