BACKGROUND: Rapid diagnosis of acute myocardial infarction (AMI) in the emergency department (ED) is often hindered by the limitations of the electrocardiogram (ECG). Speckle tracking echocardiography (STEch) is a semiautomated, computer-assisted process that provides accurate detection of regional ventricular wall motion abnormalities and can be performed at the bedside by operators with limited experience. CASE REPORTS: Two separate patients, each with history and ECG findings concerning for AMI, were evaluated using STEch performed by an emergency physician...

Despite the use of reperfusion therapies in the last decades, acute myocardial infarction further remains one of the most frequent causes of mortality. This is mainly caused by changes in the ventricular architecture leading to ventricular remodeling, followed by progressive development of heart failure. Transthoracic echocardiography is a non-invasive instrument which can provide information about the extent of the ischemic process and its consequences but can also predict the outcomes after myocardial infarction...

Left atrial (LA) work can be measured through speckle tracking echocardiography by calculating LA pressure-strain loop area, which includes two distinct phases of active contraction/relaxation (A-work) and passive dilation/emptying (V-work). Echocardiographic and hemodynamic data were acquired at baseline and during occlusions of left anterior descending (LAD: n = 7) and left circumflex (LCx: n = 9) coronary arteries in dogs. Left ventricular (LV) circumferential strain was decreased and mean LA pressure was increased in both occlusions...

OBJECTIVES: The ventricle undergoes adverse remodeling after myocardial infarction, resulting in abnormal biomechanics and decreased function. We hypothesize that tissue-engineered therapy could minimize postischemic remodeling through mechanical stress reduction and retention of tensile myocardial properties due to improved endothelial progenitor cell retention and intrinsic biomechanical properties of the hyaluronic acid shear-thinning gel. METHODS: Endothelial progenitor cells were harvested from adult Wistar rats and resuspended in shear-thinning gel...

A 68-year-old man with a non-ST elevation myocardial infarction (NSTEMI) presented with a low risk profile indicating invasive revascularization within 72 h. However, left ventricular (LV) global longitudinal strain (GLS) calculated by two-dimensional speckle tracking echocardiography (2D-STE) in the Emergency Room showed substantial myocardial infarction. Therefore, urgent reperfusion therapy was decided and delivered within 30 min from hospital admission. LV GLS fully recovered after the invasive procedure and the final infarct size was 7%...

BACKGROUND: Following acute ST elevation myocardial infarction (STEMI), restoration of large-vessel patency does not mean complete perfusion recovery. Little is known regarding the predictors of successful myocardial reperfusion for the STEMI patients undergoing pharmacologic and mechanical reperfusion strategies. AIM OF THE WORK: The aim of this clinical study was to find out the predictors of myocardial functional recovery following reperfusion of acute STEMI, represented by 3-month global longitudinal strain (GLS) value assessed by speckle tracking echocardiography...

BACKGROUND: Coronary artery disease is the most prevalent manifestation among cardiovascular diseases. Despite modern treatment, risk of ischemic complications in patients with acute coronary syndrome (ACS) remains important. The late Na+ current blocker ranolazine has shown to reduce the risk of recurrent ischemia and worsening of angina in patients with non-ST-segment elevation ACS by possibly improving myocardial perfusion, but up to now no trial has addressed whether this enhanced perfusion also leads to a decrease in ischemic myocardium of patients with ACS...

BACKGROUND: Cardiac rehabilitation (CR) exercise training is beneficial after myocardial infarction (MI). Whilst the peripheral adaptations to training are well defined, little is known regarding the effect on left ventricular (LV) remodelling, particularly LV function. Efficient LV ejection and filling is achieved through deformation and rotation of the myocardium in systole and diastole - LV mechanics. The response of LV mechanics to CR exercise training in MI patients is unknown. METHODS: In this observational exploratory study, 36 (of 40 enrolled) male, MI patients completed either 10-weeks of twice-weekly gym based cardiovascular exercise at 60-80% VO2peak (n=18), or a non-exercise control period (n=18)...
