What is Agina?
Acute angina is the condition that occurs when suddenly does not blood into the heart. Symptoms usually include sudden chest pain, nausea, dizziness and heart palpitations and tend to disappear at rest. For this reason, it differs from a heart attack, although this is a common symptom of coronary arteries, which means it deserves immediate medical attention. In many cases, this problem is caused by coronary arteries that have become too narrow to allow sufficient blood to flow to the heart.
Most cases of acute angina occur due to activity, including during or just after exercise, heavy food or even stress. All these activities may require more oxygen of blood that flows into the heart than usual, resulting in narrow coronary arteries will not be able to keep up with demand. In most cases the symptoms disappear within minutes as the patient either rests or inserts the nitroglycerin tablet for the abstain because both actions can SNto outer blood pressure. This is what separates the symptoms of acute angina from the symptoms of a heart attack, because the signs of the last state usually do not disappear with rest.
There are two types of this condition, with stable angina. Patients with stable angina usually have an idea of when their symptoms occur because they often occur when they are active and disappear with rest or nitroglycerin. On the other hand, Angina is more serious, with symptoms that may occur at any time, and usually do not leave rest or nitroglycerin. In fact, this condition usually precedes a heart attack, so it requires immediate medical attention. Fortunately, this type is much more rare than stable angina.
The most common symptom of acute angina is usually discomfort on the chest, which is usually described as pressure, difficulty or even sharp stab pain. This sign can be accompanied by a palpitations of the heart,With the feeling that the heart will pound the chest. Starting, nausea and even vomiting may occur simultaneously, causing the patient to be seriously unpleasant. Another symptom of acute angina is often dizziness or shortness of breath, which is due to reduced oxygen flow into the brain. Not surprisingly, anxiety, sweating and fatigue also often occur when acute angina is suddenly ongoing, especially if the patient is not aware of what is happening.
