Coronary artery disease (CHD)<\/strong> is the most frequent cause of death in western industrialized countries (1<\/a>) for men and women (2<\/a>). Arteriosclerosis (“vascular calcification”) causes the narrowing of the coronary vessels (coronary arteries) (5<\/a>). Coronary artery disease is also known as ischemic heart disease (6<\/a>) because a narrowing in a coronary vessel can lead to a lack of oxygen (ischemia) in parts of the heart (4<\/a>). This condition can cause a heart attack<\/a>\u00a0(3<\/a>). You can read all about Coronary artery disease here.<\/span><\/p>\n<\/div>\n ICD codes for this condition are I24, <\/span>I20, and <\/span>I25<\/span><\/span><\/p>\n Coronary artery disease is a serious disease of the heart that causes<\/a> circulatory problems of the heart muscle. The reason for this is narrowed coronary arteries. These arteries are also called “coronary arteries” or “coronaries”. They surround the heart muscle in a ring shape and supply it with oxygen and nutrients.<\/p>\n Coronary artery disease is caused<\/a> by arteriosclerosis (calcification of the coronary arteries): blood fats, blood clots (thrombi) and connective tissue accumulate in the inner walls of the vessels. This reduces the inner diameter of the vessels so that the blood flow is hindered.<\/p>\n A typical symptom of coronary artery disease<\/a> is a feeling of tightness in the chest (angina pectoris), which increases under physical exertion due to a mismatch between oxygen supply and oxygen consumption (coronary insufficiency). A heart attack or sudden cardiac death can be triggered by this disease<\/a>. Coronary artery disease (CHD) is one of the most important widespread diseases. It is more likely to affect men, who on average also contract it earlier than women.<\/p>\n Coronary artery disease (CHD) is defined as a condition in which arteriosclerosis (“vascular calcification”) leads to a lack of blood flow and thus to an imbalance between oxygen supply and oxygen consumption (coronary insufficiency) in parts of the heart muscle.<\/p>\n Depending on the extent of the arteriosclerotic changes, Coronary artery disease can be divided into the following degrees of severity:<\/p>\n Among the main branches are their outgoing branches, i.e. the entire area of the river where they supply the heart muscle.<\/p>\n<\/div>\n<\/div>\n<\/section>\n The symptoms depend on how much the coronary arteries are constricted by coronary artery disease<\/a> and where the bottleneck is located. Slight constrictions often do not cause symptoms<\/a>. However, coronary artery disease causes typical symptoms<\/a> if the vessels are severely constricted:<\/p>\n Coronary artery disease typically manifests itself as chest pain, tightness in the chest or a burning sensation behind the breastbone. Doctors refer to this condition as angina pectoris<\/a>. The symptoms occur mainly when the heart needs more oxygen, i.e. during physical or mental stress. The pain of angina pectoris often radiates into the left arm, but sometimes also into the neck, neck, back, jaw, teeth, or upper abdomen. “( feeling like a ring around the chest ).<\/p>\n Responsible for the pain is a lack of oxygen in the heart muscles when the coronary vessels are narrowed in the course of coronary artery disease<\/a>. If the pain decreases due to the administration of the vasodilating drug nitroglycerin, this is a clear indication of the presence of angina pectoris.<\/p>\n If a coronary vessel is narrowed by 70 percent of its normal width (stenosis), angina pectoris symptoms usually occur at rest. So-called heart stitches (short stitches in the chest) are not a specific indication of Coronary artery disease.<\/p>\n Coronary artery disease often also triggers cardiac arrhythmia. The lack of oxygen in the heart muscle also affects the electrical impulses (excitation conduction) in the heart.<\/p>\n Cardiac arrhythmia caused by coronary artery disease<\/a> can be confirmed by an ECG (electrocardiogram) and assessed for its potential danger. This is because many people have harmless cardiac arrhythmias and do not suffer from coronary artery disease.<\/p>\n Some people with this condition, especially diabetics, have no or hardly noticeable symptoms. In this case, one speaks of silent ischemia (deficient blood circulation). In most cases, the nerves of the heart and the entire body are so damaged by diabetes mellitus<\/a> that they no longer transmit pain signals correctly (diabetic neuropathy).<\/p>\n The heart muscle is thus damaged without the diabetic noticing. Coronary artery disease symptoms<\/a> can also be untypical in people over 75 years of age. They can manifest themselves as nausea and dizziness, for example, without typical chest or left arm pain.<\/p>\n<\/div>\n<\/div>\n<\/section>\n Coronary artery disease develops over the years through the interaction of various causes<\/a> and risk factors. Numerous scientific studies prove that coronary artery disease is related to the risk factors<\/a> mentioned here. Many of these can be avoided by adopting an appropriate lifestyle. This can drastically reduce the risk of developing it.<\/p>\n In people with coronary artery disease, the blood flow to the heart muscle is disturbed<\/a>. This is caused by a narrowing of the coronary arteries due to fat or calcium deposits (arteriosclerosis or coronary sclerosis). These deposits are located in the vessel wall of the coronary vessels and form so-called plaques<\/strong>, which constrict the vessel diameter at one or more points.<\/p>\n As a result, too little blood flows through the coronary vessels and an oxygen deficiency develops in the heart muscle (ischemic heart disease). This results in a mismatch between oxygen demand and oxygen supply (coronary insufficiency). This is particularly noticeable during exercise. If the diameter of the coronary vessels is reduced by half, circulatory disorders usually also occur.<\/p>\n Influensible risk factors for Coronary artery disease:<\/p>\n<\/h2>\n
