Plaque build-up often doesn’t cause symptoms, but it can block blood flow to vital organs like your heart. Coronary artery disease occurs when atherosclerosis affects the arteries supplying ...
A lung cavity or pulmonary cavity is an abnormal, thick-walled, air-filled space within the lung. [1] Cavities in the lung can be caused by infections, cancer, autoimmune conditions, trauma, congenital defects, [2] or pulmonary embolism. [3] The most common cause of a single lung cavity is lung cancer. [4]
The thrombus then travels downstream to other blood vessels, where the blood clot may partially or completely block blood flow. If the blood flow is completely blocked, cell deaths occur due to the lack of oxygen supply to nearby cells, resulting in necrosis. [83] The narrowing or obstruction of blood flow can occur in any artery within the body.
A vulnerable plaque is a kind of atheromatous plaque – a collection of white blood cells (primarily macrophages) and lipids (including cholesterol) in the wall of an artery – that is particularly unstable and prone to produce sudden major problems such as a heart attack or stroke.
Cardiologists share the truth about when blood vessel plaque buildup becomes dangerous.
The most frequent cause of MI is the rupturing of an atherosclerotic plaque formed in CAD. Plaque rupture exposes the subendothelial matrix beneath the plaque, initiating thrombus formation within the vasculature. [7] The thrombus deposits on the ruptured plaque to completely block the coronary artery, halting oxygen supply to cardiomyocytes.
Sleep apnea is a common sleep disorder that affects more than 20 percent of people in the United States. It happens when your breathing temporarily stops while you sleep. Depending on the severity ...
Drugs can increase a person's risk of aspiration through multiple mechanisms. [6] Medications including sedatives, hypnotics, and antipsychotics can result in decreased level of consciousness and loss of cough and swallow reflexes. [7] Long-term use of proton pump inhibitors can lead to overgrowth of gastric bacteria and increase risk of ...
