Isovolumic relaxation intraventricular pressure difference predicts elevated left ventricular end-diastolic pressure in patients with coronary artery disease [PDF]

Scientific Reports
Current guideline for evaluating diastolic function requires multiple parameters to identify patients with elevated left ventricular end-diastolic pressure (LVEDP). However, the intermediate result still exists and may cause LVEDP undetermined.

ABSTRACT Alzheimer's Disease (AD) is a global health issue, affecting over 6 million people in the United States, with that number expected to increase as the population ages. As a neurodegenerative disorder that affects memory and cognitive functions, it is well established that AD is associated with cardiovascular risk factors beyond only cerebral ...

Diastolic Dysfunction in Neonates With Hypoxic-Ischemic Encephalopathy During Therapeutic Hypothermia: A Tissue Doppler Study

Frontiers in Pediatrics, 2022
Diastolic dysfunction often complicates myocardial ischemia with increased mortality rates. However, less is known about diastolic function after perinatal asphyxia in neonates with hypoxic-ischemic encephalopathy (HIE) during therapeutic hypothermia (TH)

Is High Temporal Resolution Achievable for Paediatric Cardiac Acquisitions during Several Heart Beats? Illustration with Cardiac Phase Contrast Cine-MRI. [PDF]

PLoS ONE, 2015
During paediatric cardiac Cine-MRI, data acquired during cycles of different lengths must be combined. Most of the time, Feinstein's model is used to project multiple cardiac cycles of variable lengths into a mean cycle.To assess the effect of Feinstein ...

Validity of tissue Doppler markers in the assessment of pulmonary hypertension

The Egyptian Heart Journal, 2014
The accuracy of tissue Doppler parameters of right ventricular function including Isovolumic relaxation time (IVRT) and Isovolumic contraction time (IVCT) have not been validated sufficiently in pulmonary hypertensive patients (pts).

Myocardial Motion Analysis for Determination of Tei-Index of Human Heart

Sensors, 2010
The Tei index, an important indicator of heart function, lacks a direct method to compute because it is difficult to directly evaluate the isovolumic contraction time (ICT) and isovolumic relaxation time (IRT) from which the Tei index can be obtained. In
