myocardial stunning/infarction

We report a male patient who had recurrent coronary artery spasm on withdrawal from cardiopulmonary bypass, which led to myocardial infarction and stunned myocardium. The spasm responded to conventional medication. Transesophageal echocardiogram showed no remarkable asynergy during the operation.

BACKGROUND The mechanism through which ischemic preconditioning causes cardioprotection is unknown. The present study investigated the role of stunning in preconditioning. RESULTS We studied three different protocols of preconditioning: two cycles of 2-minute ischemia separated by 5-minute

Background: NPC is a member of the leumedins and is an inhibitor of leukocyte adhesion to endothelium via blockage of integrin binding. NPC 15669 also may have antiplatelet effects. We tested the efficacy of the novel leukocyte recruitment inhibitor NPC 15669 on myocardial stunning (MS) and

Myocardial stunning commonly occurs after cardiopulmonary bypass (CPB). Myocardial stunning can be cardioprotective under some conditions, but in other situations may actually contribute to myocardial infarction (MI). Vascular endothelial stunning may be one of the mechanisms by which myocardial

Postconditioning, i.e., brief intermittent episodes of myocardial ischemia-reperfusion performed at the onset of reperfusion, reduces infarct size after prolonged ischemia. Our goal was to determine whether postconditioning is protective against myocardial stunning. Accordingly, conscious

OBJECTIVE We sought to prospectively identify patients with stunning and hyperkinesia at hospital discharge on the basis of mismatches between left ventricular (LV) function and infarct size as assessed by technetium-99m (Tc-99m) sestamibi perfusion tomographic imaging. BACKGROUND Mechanical indexes

Quantitation of perfusion defect size using tomographic imaging with technetium-99m-hexakis-2-methoxy isobutyl isonitrile was performed at the time of hospital discharge in 32 patients with a first myocardial infarction who underwent successful coronary reperfusion within 8 h of the onset of chest

Low dose (5 to 10 micrograms/min) dobutamine echocardiography was used to predict the presence of reversible contractile dysfunction (myocardial stunning) after myocardial infarction successfully revascularised in the acute phase of primary angioplasty. The investigation was undertaken in 40

Stress-induced myocardial stunning is defined as a syndrome of acute chest pain, ST-T changes on the ECG and transient left ventricular apical wall motion abnormalities mimicking acute myocardial infarction but with surprisingly normal coronary angiography findings. The aim of this retrospective

BACKGROUND Strain rate (SR) imaging (SRI) is a tissue Doppler-based method of regional myocardial deformation imaging. The aim of this study was to see whether SRI could quantify changes in myocardial mechanical function after an acute myocardial infarction, and to follow the time course of these

We report a case of myocardial stunning after acute myocardial infarction. In the hyperacute phase of myocardial infarction, the patient's coronary arteries showed normal features on coronary angiography during extensive ST-segment elevation observed on a standard 12-lead electrocardiogram and

Emergent cardiac catheterization was performed on a 70-year-old female patient who was admitted for further evaluation of acute myocardial infarction. Coronary angiography didn't reveal any significant stenotic lesion, but levogram showed extensively abnormal contractility around the center of the

Background: Left ventricular remodeling following ST-elevation myocardial infarction (STEMI) is associated with poor outcome, including heart failure (HF). Neprilysin inhibition leads to improved outcome in patients with altered left

Stunned myocardium of right ventricle was studied by radionuclide angiography (RNA) and Thallium myocardial scintigraphy (TL) in 39 patients with inferior myocardial infarction with and without right ventricular myocardial infarction (RVMI). RNA was performed within 1 week of the onset (acute phase)

Microvascular integrity demonstrated by myocardial contrast echocardiography (MCE) predicts functional recovery after an acute myocardial infarction (AMI). Recently, parametric imaging-based quantitative MCE has been developed. Our aim was to assess the usefulness of parametric imaging-based
