Validity of resting strain/strain rate in prediction of myocardial viability

AbstractTo evaluate the validity of the resting strain/strain rate measurements in predicting myocardial viability taking delayed enhancement cardiac magnetic resonance imaging as the gold standard. A cohort of 60 patients at three months followed up after acute myocardial infarction were recruited for this study. Resting echocardiography with offline analysis of deformation indices and gadolinium contrast enhanced cardiac magnetic resonance imaging were applied for all patients. For the final assessment, 268 segments with significant resting wall motion abnormalities were presented. Resting longitudinal strain was significantly (p

AbstractAimsEpicardial adipose tissue (EAT) has been linked to impaired reperfusion success after percutaneous coronary intervention (PCI). Whether EAT predicts myocardial damage in the early phase after acute myocardial infarction (MI) is unclear. Therefore, we investigated whether EAT in patients with acute MI is associated with more microvascular obstruction (MVO), greater ST-deviation, larger infarct size and reduced myocardial salvage index (MSI).Methods and resultsThis retrospective analysis of a prospective observational study including patients with acute MI (n = 54) undergoing PCI and 12 healthy matc...

MINOCA is diagnosed in patients who fullfilled the fourth universal definition of AMI in the absence of significant obstructive coronary artery disease on coronary angiography. MINOCA is a group of heterogeneous diseases with different pathophysiological mechanisms requiring multimodality imaging.

We report the unusual case of a 57-year-old female patient with AL amyloidosis presenting with an ST segment elevation myocardial infarction due to coronary artery embolization (CE). The patient reported a history of exertional dyspnoea along with episodes of haemoptysis for the last few months. Her coronary angiography demonstrated embolization of the distal segment of the left anterior descending artery. The main findings of her cardiac ultrasound included concentric left ventricular hypertrophy, mildly impaired left ventricular systolic function, left atrium enlargement and a restrictive-like filling pattern, while her ...
