Is glycated haemoglobin a sensitive index to identify left ventricular dysfunction two months after acute myocardial infarction in normotensive subjects?
2006, International Journal of CardiologyHyperbaric oxygen treatment does not affect left ventricular chamber stiffness after myocardial infarction treated with thrombolysis
2004, American Heart JournalCitation Excerpt :Of various Doppler indexes, DT has been shown to be the most valuable for quantitative assessment of LV chamber stiffness, since it appears to be independent of heart rate, afterload, and contractility.6,32–34 DT is mostly determined by infarct size.6–9 The same was shown for E/A ratio, but to a significantly lesser extent.6
Noninvasive Estimation of Left Ventricular Filling Pressure by E/e′ Is a Powerful Predictor of Survival after Acute Myocardial Infarction
2004, Journal of the American College of CardiologyCitation Excerpt :There are several potential explanations for this. Higher LV filling pressures are usually indicative of larger infarcts with more severe systolic dysfunction (1,23–26). In addition, LV pressure overload predisposes to ventricular remodeling, neurohormonal activation, and increased excitability (4,27,28), all of which would be expected to adversely affect the outcome.
Myocardial viability independently influences left ventricular diastolic function in the early phase after acute myocardial infarction
2002, Journal of the American Society of EchocardiographyCitation Excerpt :The current study showed that during the acute phase of myocardial infarction, patients with Mviab have significantly lower LVEDP independent of LV volume and WMSI. LV diastolic dysfunction is strongly linked to systolic myocardial dysfunction as a result of ischemic injury.16,17 Clinical and animal studies have identified myocardial infarct size as a major determinant of LV dilation.18-22
