When the oxygen is the blood falls below the requirement of the heart muscles, a discomfort arises in the chest which is known as Angina. This shortage of oxygen usually occurs due to the coronary arteries becoming narrow called as Arteriosclerosis.
Usual Symptoms of Angina:
1. Squeezing in Chest
2. Heaviness in the test or aching in Chest
3. Tightening beneath the breastbone
4. Often this pain also reflects at the neck, arms, jaw and back.
5. In some cases sweating, heartburn, cramping and breath shortage is reported.
Angina is mainly reported at the time of exertion or after a heavy meal. Severe emotional stress can also lead to Angina. At this stage the muscles of the heart demand more supply of oxygen that the arteries can supply leading to the condition. This condition can last from one minute to 15 minutes and can be normalized by taking rest or by placing a tablet under the tough containing Nitroglycerin. What Nitroglycerin does is it relaxes the blood vessels and brings your blood pressure down.
Even though heart is a pumping machine and supplies blood to the whole body, it itself needs blood. The two arteries namely left and right coronary arteries supply blood to the muscle walls of the heart.
These Coronary arteries over a period of time, become narrow due to deposit of fatty material including cholesterol inside the walls. These deposits make the task of supply of oxygenated blood to the heart muscle a difficult task. THis problems is aggrevated when the heart demands more oxygen especially during exercises or any physical activity. Angina is different from an usual Heart Attack as in an Heart Attack, the arteries are completely clotted and blocked.
In case of Angina the blood flow is not completely blocked but is only restricted to a severe extend.
