Regional myocardial work by strain Doppler echocardiography and LV pressure: a new method for quantifying myocardial function.
There is a need for better methods to quantify regional myocardial function. In the present study, we investigated the feasibility of quantifying regional function in terms of a segmental myocardial work index as derived from strain Doppler echocardiography (SDE) and invasive pressure. In 10 anesthetized dogs, we measured left ventricular (LV) pressure by micromanometer and myocardial longitudi...
متن کاملQuantification of Regional Myocardial Function following Acute Myocardial Infarction by Ultrasonic Strain Rate and Strain Imaging
Objectives: The rapid diagnosis and early risk stratification of patients presenting with acute myocardial infarction (AMI) is important. In experimental setting ultrasonic strain rate (SR) and strain (S) have been shown to identify changes in deformation predictive of ischemia. We sought to evaluate and compare regional myocardial function at “the risk zone” (ARZ) supplied by the culprit coron...
متن کاملRegional pulmonary function analysis using image registration and 4DCT
Current radiation therapy (RT) planning for limiting lung toxicity assumes a uniform distribution of lung function with little consideration to the spatial and temporal pattern of lung function. Establishment of relationships between radiation dose and pulmonary function change can help predict and reduce the RT-induced pulmonary toxicity. Baseline measurement uncertainty of pulmonary function ...
متن کاملCharacterization of normal regional myocardial function by MRI cardiac tagging.
PURPOSE The aim of this study was to establish reference values for segmental myocardial strain measured by magnetic resonance (MR) cardiac tagging in order to characterize the regional function of the heart. MATERIAL AND METHODS We characterized the left ventricular (LV) systolic deformation in 39 subjects (26 women and 13 men, age 58.8 ± 11.6 years) whose cardiological study had not reveale...
متن کاملComparison of serum parathyroid hormone level between patients with acute myocardial infarction, unstable angina, and normal coronary function
Background: Nowadays, cardiovascular diseases (CVDs) are among the most common causes of mortalities worldwide. Parathyroid hormone (PTH) has an important role in the pathogenesis of CVDs. The aim of the current study was to compare serum PTH levels between patients with acute myocardial infarction (MI), unstable angina, and normal coronary function. Methods: This descriptive and analytic stud...
