Left Ventricular Dyssynchrony After Acute Myocardial Infarction is a Powerful Indicator of Left Ventricular Remodeling
BACKGROUND AND OBJECTIVES Left ventricular (LV) remodeling (LVR) after an acute myocardial infarction (AMI) has important clinical implications. We have investigated the prognostic relevance of ventricular systolic dyssnchrony as an indicator of LVR after an AMI. SUBJECTS AND METHODS We enrolled 92 patients (males, 72.8%; mean age, 61.0+/-13.0 years) with an AMI who underwent successful percu...
متن کامل[Cardiac dyssynchrony correlates with left ventricular remodeling after myocardial Infarction].
BACKGROUND Cardiac dyssynchrony is common in advanced heart failure (HF), but the changes in cardiac synchrony after myocardial infarction (MI) have not been adequately descríbed. AIM To study the relationship between cardiac synchrony and left ventricular remodeling after acute myocardial infarction. MATERIAL AND METHODS Forty nine patients aged 59+/-10 years (77% men) with a first episode...
متن کاملReduced left ventricular torsion early after myocardial infarction is related to left ventricular remodeling.
BACKGROUND Left ventricular (LV) torsion is emerging as a sensitive parameter of LV systolic myocardial performance. The aim of the present study was to explore the effects of acute myocardial infarction (AMI) on LV torsion and to determine the value of LV torsion early after AMI in predicting LV remodeling at 6-month follow-up. METHODS AND RESULTS A total of 120 patients with a first ST-segm...
متن کاملDoes left ventricular dyssynchrony immediately after acute myocardial infarction result in left ventricular dilatation?
BACKGROUND Reverse remodeling of the left ventricle (LV) is one of the advantageous mechanisms of cardiac resynchronization therapy (CRT). Substantial LV dyssynchrony seems mandatory for echocardiographic response to CRT. Conversely, LV dyssynchrony early after acute myocardial infarction may result in LV dilatation during follow-up. OBJECTIVE The purpose of this study was to evaluate the rel...
متن کاملLeft Ventricular Diastolic Dyssynchrony in Post-Myocardial Infarction Patients: Does It Predict Future Left Ventricular Remodeling?
Left ventricular (LV) remodeling is well-known complication after myocardial infarction (MI) and numerous studies have emphasized the clinical importance of ventricular remod-eling. 1-4) In these literatures, progressive LV dilatation and decreased LV ejection fraction were major determinants in future development of heart failure and long term survival. That is why early recognition of patient...
