What tissues are most susceptible to ischaemia?
Renal cortical cells are the most sensitive to ischemia because renal oxygen levels are highest in this region of the kidney and progressively decrease from the outer medulla to the depths of the papillae.
What causes reperfusion injury?
Reperfusion injury, sometimes called ischemia-reperfusion injury (IRI) or reoxygenation injury, is the tissue damage caused when blood supply returns to tissue (re- + perfusion) after a period of ischemia or lack of oxygen (anoxia or hypoxia).
What is tissue ischemia?
Ischemia is a deficiency of blood in a tissue that is caused by constriction or obstruction of local blood vessels and results in a reduced supply of oxygen to the tissue.
What is reperfusion injury quizlet?
Reperfusion injury. Injury caused by the restoration of blood flow after an ischemic episode.

How do you fix ischemia?
Treatment for myocardial ischemia involves improving blood flow to the heart muscle. Treatment may include medications, a procedure to open blocked arteries (angioplasty) or bypass surgery. Making heart-healthy lifestyle choices is important in treating and preventing myocardial ischemia.
How do you know the end is near with congestive heart failure?

How do you fix diastolic heart failure?
Medications may be prescribed to treat or reduce symptoms of diastolic heart failure. They include: Angiotensin-Converting Enzyme Inhibitors (ACE Inhibitors) and Angiotensin Receptor Blockers (ARBs), which relax blood vessels to improve blood flow.
