Hypoperfusions of the heart can be caused by many factors. This information serves as general guidance and should not be used as a self-diagnosis or self-treatment. It should not be considered as a replacement for visiting your GP!


A stenosis is a restriction of blood vessels or other hollow organs. Causes, symptoms, diagnosis and treatment depend on the location and clinical findings. Blood vessel stenoses are mostly caused by arteriosclerosis (calcification) but they can also be the result of injury or inflammation. For coronary heart disease (CHD), stenoses can often be detected by anginose discomfort (angina pectoris). A stenosis is often the precursor to a closure leading to an acute heart attack.

Angina pectoris

Angina pectoris is a paroxysmal pain in the chest caused by temporary disruption to circulation to the heart. This is usually caused by a narrowing of one or more coronary vessels. Angina pectoris is therefore not an illness in itself but rather a symptom/name for the clinical symptoms of an acute coronary insufficiency.

Coronary artery disease

According to the Center for Disease Control:

Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis. Coronary artery disease (CAD) is the most common type of heart disease in the United States. For some people, the first sign of CAD is a heart attack. You and your health care team may be able to help you reduce your risk for CAD.

Causes of CAD
Too much plaque buildup and narrowed artery walls can make it harder for blood to flow through your body. When your heart muscle doesn’t get enough blood, you may have chest pain or discomfort, called angina. Angina is the most common symptom of CAD. Over time, CAD can weaken the heart muscle. This may lead to heart failure, a serious condition where the heart can’t pump blood the way that it should. An irregular heartbeat, or arrhythmia, also can develop.
