The patches also significantly reduced infarct size, which is the area of dead muscle; heart-muscle wall stress
and heart-muscle enlargement; as well as significantly reducing apoptosis, or programmed cell death, in the scar border area around the dead heart muscle.
When determining the minimum depth to bury the pipe, the compressive wall stress
on the pipe from exterior forces should be kept less than the allowable compressive stress of the HDPE material.
Objective: Rupture of Aortic Aneurysms (AA), which kills more than 30 000 persons every year in Europe and the USA, is a complex phenomenon that occurs when the wall stress
exceeds the local strength of the aorta due to degraded properties of the tissue.
Instead, AAA appears to be a multifactorial process involving inflammation, matrix degradation, thrombosis, and aortic wall stress
One could make the case that treating earlier in the LV remodeling process provides more viable tissue that compliments the mechanistic theory of the PARACHUTE which is to reduce volume, thereby reducing wall stress
in the upper chamber of the LV, and to synchronize wall motion during systolic contraction by replacing the eccentric wall motion in the apical region with a more compliant device.
Its release is stimulated by an increase in ventricular wall stress
To carry out a quantitative comparison, wall stress
values were exported for two regions of interest: (a) the complete aneurysm sac (approx.
He has written for the Wall Stress
Journal and has won the Keystone Press Award three times.
The primary study endpoint was change in N-terminal of the prohormone brain natriuretic hormone (NT-proBNP), a biomarker of left ventricular wall stress
, through 12 weeks.
13,14) The wall stress
of any segment of the myocardium is therefore highly dependent upon the local geometry, particularly the radii of curvature of the ventricle wall at that location.
Because of the loss of viable myocardium after an MI, the heart works under elevated wall stress
, which results in progressive myocardial hypertrophy and left ventricular dilation that leads to heart failure.
This leads to a vicious cycle by causing wall stress
