Among the causes of ischemia are sickle cell anemia, ventricular tachycardia, the compression of blood vessels, and blood clots. Extremely low blood pressure, congenital heart defects, and the buildup of plaque in the arteries also can cause this condition. Sickle Cell Anemia Sickle cell anemia ...
Brain:This can cause astroke. Legs:Doctors call this “critical limb ischemia.” It’s a severe condition you can get withperipheral artery disease(PAD). That’s a condition where you have plaque build-up in the arteries of your leg. It causes intensepain, even when you’re resting. If...
Ischemia refers to the condition in which the muscles of the heart do not get an adequate supply of oxygen. This mostly happens because of reduced blood flow to the cardiac muscles either due to complete blockages or due to a partial block in the blood vessels that carry blood. This condit...
How can a stroke cause aphasia? What is acute myocardial ischemia? Why does ischemic heart disease lead to dilated cardiomyopathy? What is a cerebrovascular accident (stroke)? Explain what happens to brain cells and the consequences of the event. What causes coronary artery calcification? What type...
Ischemia can be developed in any part of the body, affecting any tissue. Ischemia can cause heart attacks andstroke, especially in cardiac ischemia or lack of blood flow to the heart. In very rare cases, ischemia can affect the intestines causing pain in the abdomen, blood in stools and al...
What ECG Changes might Myocardial Ischemia Cause other than ST Segment Elevation or Q Waves and What are the Differential Diagnoses of these Changes?general discussion of ST and T wave, and U wave abnormalities in ischemiaT wave abnormalitiesdifferential diagnosis of T wave inversion...
A leading hypothesis is that NDEs are caused by a lack of oxygen (hypoxia) or blood flow (ischemia) to the brain, which can trigger hallucinations and out-of-body experiences. The spike in brain activity, seen in the aforementioned studies, may also play a role in these vivi...
The retina develops from the diencephalon, and so remains part of the CNS; retinal ischemia activates the same pathways as ischemic injury in other CNS areas, and can therefore offer strong evidence regarding the pathological processes follow- ing injury. This makes the study of retinal ischemia ...
Myocardial ischemia or myocardial infarction can damage the heart, reducing the heart’s pumping function and causing fatal cardiac arrhythmias. If the coronary artery is completely blocked, it will cause a heart attack. This is viewed as the leading cause of death in patients with cardiovascular ...
What causes intestinal ischemia? What causes a macular hole? What causes autonomic dysreflexia? What causes the appendix to malfunction? What causes chronic inflammation of the bladder? What causes pleural effusion in cats? What causes bilateral pleural effusion?
