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 ...
The causes of heart disease depend on the type you have. For instance, unhealthy lifestyle habits can contribute to the plaque buildup that leads to coronary artery disease. ... (a drug used in ...
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [1] [2]The material consists of mostly macrophage cells, [3] [4] or debris, containing lipids, calcium and a variable amount of fibrous connective tissue.
Coronary occlusion is caused by plaque inside of the blood vessels that direct oxygen rich blood to the heart. [8] Plaque is caused by fatty deposits and scar tissue that cling to the walls of coronary arteries. [9] The development of plaque takes years and leads to stenosis of the coronary arteries and progressively reduces blood flow. [8]
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.
Henry VIII's first wife Catherine of Aragon's death is believed to have resulted from heart cancer. [citation needed] Eric Carr, American musician, drummer of the rock band Kiss, died of heart cancer. [10] Alexander Belov, Soviet basketball player. [11] Mimi Lerner, Polish-American mezzo-soprano, died of heart tumor. [12]
Hemorrhagic infarct, apex lower lobe, left lung Heart: Myocardial infarction (MI), commonly known as a heart attack, is an infarction of the heart, causing some heart cells to die. This is most commonly due to occlusion (blockage) of a coronary artery following the rupture of a vulnerable atherosclerotic plaque, which is an unstable collection ...
