A Pilot Study to Predict Future Cardiovascular Events by Novel Four-dimensional Echocardiography Global Area Strain in ST-Elevation Myocardial Infarction Patients Managed by Primary Percutaneous Coronary Intervention.

Context: Four-dimensional speckle-tracking echocardiography (4D-STE) is ideal to accurately assess myocardial deformation. The novel 4D global area strain (GAS) uses global longitudinal and global circumferential strains (GCSs) to detect subtle changes in myocardium.

Aims: The aim of this study was to determine the predictive value of 4D strain echocardiography for major adverse cardiovascular events (MACEs) in ST-elevation acute myocardial infarction (STEMI) patients after successful reperfusion by primary percutaneous coronary intervention (PCI).

Independent predictors of developing pulmonary hypertension in heart failure with reduced versus preserved ejection fraction.

Objectives: To investigate the different clinical and echocardiographic predictors of evolving PH in patients with heart failure with and without reduced ejection fraction.

Methods And Results: The study included 153 heart failure patients with reduced ejection fraction (HFrEF) ( = 89) and preserved ejection fraction (HFpEF) ( = 64) both of which were subdivided into 2 subgroups according to the presence of PH. All patients were subjected to detailed clinical assessment and full transthoracic echocardiogram.

Mitral Annular Plane Systolic Excursion-Derived Ejection Fraction: A Simple and Valid Tool in Adult Males With Left Ventricular Systolic Dysfunction.

Objectives: Validation of a mitral annular plane systolic excursion (MAPSE)-derived formula to calculate the ejection fraction where EF = 4.8 × MAPSE (mm) + 5.8 in adult males with left ventricular (LV) dysfunction.

Predictors of contractile recovery after revascularization in patients with anterior myocardial infarction who received thrombolysis.

Background: Identification of viable myocardium after myocardial infarction has gained paramount importance with the current progress in coronary revascularization.

Objective: To explore the prognostic power of certain patient characteristics to predict myocardial contractile recovery after revascularization in patients presenting with acute anterior ST elevation myocardial infarction (STEMI) who received thrombolytic therapy.

Methods: Seventy-three consecutive patients presenting with first acute anterior STEMI who had received thrombolytic therapy and had significant coronary stenosis or occlusion of the infarct-related artery amenable for revascularization were enrolled.
