Coronary heart disease (CHD) is the leading cause of death in western industrialized countries. Arteriosclerosis ("vascular calcification") causes a constriction of the coronary arteries (coronary arteries). Coronary heart disease is also referred to as ischemic heart disease, as a constriction in a coronary artery can lead to hypoxia (ischemia) in parts of the heart. Coronary heart disease can cause a heart attack. Read all important information about coronary heart disease here.

Coronary heart disease (CHD): description

Coronary heart disease (CHD) is a serious heart disease that causes circulatory disorders of the heart muscle. Reason for this are narrowed coronary vessels. These arteries are also called "coronary arteries" or "coronaries". They surround the heart muscle in a wreath and supply it with oxygen and nutrients.

The cause of coronary heart disease (CHD) is arteriosclerosis (vascular calcification) of the coronary arteries: blood lipids, blood clots (thrombi) and connective tissue are deposited in the inner walls of the vessels. This reduces the inner diameter of the vessel so that blood flow is impeded.

A typical symptom of coronary heart disease (CHD) is chest tightness (angina pectoris), which increases with physical exertion, as there is a mismatch between oxygen supply and oxygen consumption (coronary insufficiency). A heart attack or sudden cardiac death can be triggered by the coronary heart disease. Coronary heart disease (CHD) is one of the most important common diseases and has been leading the cause of death statistics in Germany for years. Coronary heart disease (CHD) is more likely to affect men who, on average, contract earlier than women.

Coronary artery disease: definition

Coronary heart disease (CHD) is defined as a condition in which arteriosclerosis ("vascular calcification") leads to deficient circulation and thus to a mismatch of oxygen supply and oxygen consumption (coronary insufficiency) in parts of the heart muscle.

Coronary artery disease: classification:

Depending on the extent of arteriosclerotic changes, coronary heart disease can be classified into the following degrees of severity:

  • Coronary artery disease - edema disease: One of the three main branches of the coronary arteries is affected by one or more narrow passages (stenoses).
  • Coronary artery disease - branch vascular disease: Two of the three main branches of the coronary arteries are affected by one or more narrow passages (stenoses).
  • Coronary artery disease - three-vessel disease: All three main branches of the coronary arteries are affected by one or more narrow passages (stenoses).
