heart muscle is working all the time, so it needs a continuous supply of oxygen, coming together with the blood.Its supply to the heart coronary artery.The more intense the heart works, the more oxygen it needs.Angina symptoms begin to appear when the coronary arteries are narrowed as a result of atherosclerosis, or when they block bloo
Generally, these symptoms are not always present, but only when intense physical activity, such as during exercise, especially when the heart requires a lotoxygen, but because of impaired patency of the arteries, it can not get it in sufficient quantities.

Classification of angina
The classification of stable angina functional class uses the concept - it indicates the level of physical activity, which typically begins the attack of the disease.
- functional class 1 is the easiest - the patients tolerate their usual load of good, but very intense stress can happen angina.
- functional class 2 includes a condition in which seizures can start at moderate loads, such as when climbing on two or more flights of stairs.Many patients with angina, which refers to this class can not pass without stopping for more than half a kilometer, and very poorly tolerate frost.
- 3 functional class.Angina attack that class begin after loads that most healthy people seem quite minor, such as after lifting a flight of stairs or after walking non-stop over distances not exceeding a few hundred meters.
- 4 functional class.This category includes forms of angina pectoris, which have the most significant impact on the quality of human life.Patients with angina may feel a pain in my heart pain in the heart - always consult a physician , after having walked for less than a hundred meters, holding up relatively easy subject, and even while at rest.
If stable angina Stable angina - one of the manifestations of coronary heart disease manifestations of the disease rather predictable and equally intense for a long time (hence the name), then the progressive angina Progressive angina - what dangers lurkHuman stress attacks can suddenly become more frequent, prolonged and intense.
Symptoms of angina
