Causes of Angina of Effort
Angina of. effort may occur from the presence of physical stress on the heart when coronary arteries cannot widen as needed because:
- The spasm of coronary arteries;
- Coronary artery atherosclerosis – the process in which cholesterol plaques (clusters) are accumulated on the walls of the arteries.
As a major sign of coronary heart disease, angina may also occur together with other disorders, such as:
- Aortic valve disorders. The aortic valve is located close to the coronary arteries, therefore, these disorders reduce the blood flow through these arteries;
- Severe anemia. This disorder causes insufficient oxygen supply to the heart muscle;
An angina of effort attack can be provoked by the following factors:
- Physical activity;
- Emotional stress;
- Leaving a warm area and encountering cold air;
- Heavy meal.
Also angina of effort can be caused by a significant increase of pressure in the right ventricle. Decrease in blood pressure, tachycardia and reduced blood oxygen levels are not the causes of this type of angina, but they have a negative effect on the condition.
