Early right ventricular dysfunction after primary percutaneous coronary intervention in anterior versus isolated inferior myocardial infarction assessed by tissue Doppler imaging and speckle tracking echocardiography.

This study hypothesized that imaging provides information indicating the right ventricular (RV) involvement after anterior or inferior ST-elevation myocardial infarction (STEMI), beyond standard electrocardiogram (ECG) due to the increasing interest in RV function and assessment techniques. This study aimed to compare RV function between anterior and inferior MI without RV involvement using different echocardiographic modalities. This study included 100 patients with anterior (50 patients) and inferior (50 patients) STEMI, who underwent primary percutaneous coronary intervention (PPCI) and two-dimensional echocardiographic imaging within 24 h after PPCI with RV function analysis by left ventricular (LV) infarct size, LV filling pressure, and RV strain rate.

Novel predictors and adverse long-term outcomes of No-reflow phenomenon in patients with acute ST elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Objectives: The no-reflow phenomenon occurs in 25% of patients with ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI), and may be associated with adverse outcomes. The aim of our study was to detect novel predictors of no-reflow phenomenon and the resulting adverse long term outcomes.

Methods: We enrolled 400 STEMI patients undergoing primary PCI; 228 patients had TIMI flow 3 after PCI (57%) and the remaining 172 patients had TIMI flow <3 (43%).

Short- and long-term prognostic value of right ventricular function in patients with first acute ST elevation myocardial infarction treated by primary angioplasty.

Introduction: Limited data are known about the prognostic value of right ventricle (RV) function in patients with first acute ST-segment elevation myocardial infarction (STEMI). The aim of this study was to investigate the prognostic value of RV dysfunction in predicting both in-hospital and long-term outcomes in these patients, irrespective of the site of necrosis.

Methods: We enrolled 502 consecutive patients with first acute STEMI treated with primary angioplasty and underwent echocardiography within 48 hours of admission.

Relation of collateral circulation with reciprocal changes in patients with acute ST-elevation myocardial infarction.

Objective: Acute STEMI is often accompanied by reciprocal ST-segment depression (RC) occurring in opposite leads, whose significance has been debated for decades. The possible role of collateral circulation in promoting RC in acute STEMI has not been identified. So our aim to find the relationship between collateral circulation and RC in STEMI patients treated with primary percutaneous intervention (PPCI).

Transmural Extent in Relation to Clinical Scoring in Non-ST Elevation Myocardial Infarction Patients: Speckle-Tracking Echocardiographic Study.

Background: To assess the extent of transmurality in non-ST elevation myocardial infarction (NSTEMI) patients using speckle-tracking echocardiography (STE) in relation to their risk categorization to improve the risk stratification of NSTEMI patients through detecting the presence of transmural infarction.

Patients And Methods: It included 96 patients with NSTEMI. All patients were subjected to GRACE score (GS) calculation, transthoracic and speckle-tracking echocardiography (STE): To detect left ventricular ejection fraction and myocardial global longitudinal strain [GLS] and circumferential strain [CS].

Value of global longitudinal strain by two dimensional speckle tracking echocardiography in predicting coronary artery disease severity.

Background: Significant coronary artery stenosis might cause persistently impaired longitudinal left ventricle (LV) function at rest. LV global longitudinal strain (LVGLS) can be accurately assessed by 2D speckle-tracking strain echocardiography(2D-STE).

Objective: We aimed to evaluate the diagnostic accuracy of LV global longitudinal strain obtained by 2D-STE in prediction of severity of CAD.

Relation between left atrial measurements and thromboembolic risk markers assessed by echocardiography in patients with nonvalvular atrial fibrillation: A cross-sectional study.

Background: Left atrium (LA) dilatation has been associated with adverse cardiovascular outcomes in patients with sinus rhythm and atrial fibrillation (AF).

Aim Of The Study: We aimed to evaluate the accuracy of left atrial (LA) size to predict transesophageal echocardiographic (TEE) markers of increased thromboembolic risk left atrial appendage (LAA) thrombus, low LAA velocities and dense spontaneous echocardiographic contrast (SEC), and also to assess the best method to evaluate LA size.

Patients And Methods: Cross-sectional study included 64 patients with nonvalvular AF undergoing transthoracic and transesophageal echocardiographic (TTE and TEE) evaluation.

Factors influencing postoperative atrial fibrillation in patients undergoing on-pump coronary artery bypass grafting, single center experience.

Background: The reported incidence of AF after CABG surgery varies from 20 to 40%, with the arrhythmia usually occurring between second and fourth postoperative days. Postoperative AF after CABG was associated with greater in-hospital mortality and worse survival at long-term follow-up. Therefore, intensive attention has focused on the prevention of AF in high-risk patients.

Value of N-terminal pro brain natriuretic peptide in predicting prognosis and severity of coronary artery disease in acute coronary syndrome.

Background: Measurement of N-terminal pro brain natriuretic peptide (NT-proBNP) in the evaluation of patients with acute coronary syndrome has appeared to be a useful prognostic marker of cardiovascular risk.

Aim Of The Work: To assess the in-hospital prognostic value of NT-proBNP in patients with acute coronary syndrome (ACS) and its relation to the severity of coronary artery disease.

Patients And Methods: This study included 132 consecutive patients with ACS, 64 patients with unstable angina (UA), 46 patients with non-ST segment elevation myocardial infarction (NSTEMI), and 22 patients with ST segment elevation myocardial infarction (STEMI).
