Unstable Angina: Frequently Asked Questions

Unstable angina refers to an increase in the number, severity or duration in episodes of angina within the previous two months. It may also include a new episode within the past month brought on by physical activity or occurring at rest. Unstable angina is frightening and disabling and can lead to a heart attack. With unstable angina, the pain is more intense, lasts longer, is brought on by less effort, occurs at rest, is progressive, or can demonstrate any combination of these factors. ...

"Unstable" angina is a form of angina that is much more serious than stable angina. Unstable angina occurs when a person is resting, asleep, or undergoes physical exertion. Severe discomfort may come on suddenly in someone who has never had angina before. Attacks may intensify or happen more often. Unstable angina is caused by blood clots that form around damaged plaque (fatty deposit) within a coronary artery. Sometimes the clot washes away after the damage has healed. ...

It is important to distinguish between the typical stable pattern of angina and "unstable" angina. Angina pectoris often recurs in a regular or characteristic pattern. Commonly a person recognizes that he or she is having angina only after several episodes have occurred, and a pattern has evolved. The level of activity or stress that provokes the angina is somewhat predictable, and the pattern changes only slowly. This is "stable" angina, the most common variety. ...

The Heart Foundation’s 'Management of Unstable Angina Guidelines - 2000' identifies the distinction between unstable angina and non-STEMI as being 'cloudy' and the diagnoses of unstable angina, minor myocardial damage and non-STEMI representing a continuum1. At the time of admission, it is likely that patients with unstable angina will receive the same care as patients with non-STEMI, and may continue to receive the same level of care throughout their stay. The point really is about the care that is received. ...

Use boolean operators AND, OR, NOT, between words as much as possible, if you don't want surprises. The PubMed search engine has some 'artificial intelligence' and tries to look for a word combination instead of separate words, if the combination makes sense. The first pattern will be searched as if it is enclosed in quotes: "unstable angina". The second pattern will be searched as: unstable AND angina. More at PubMed .

Respuesta: Use operadores booleanos (AND, OR, NOT) entre las palabras tanto como le sea posible si no desea sorpresas. El motor de búsqueda de PubMed posee cierta 'inteligencia artificial' y trata de buscar combinaciones de palabras en vez de palabras separadas, si dicha combinación tiene sentido. El primer patrón será usado como si estuviera entre comillas: "unstable angina" mientras que el segundo será utilizado como: unstable and angina. Más en PubMed .

Angina (say "ANN-juh-nuh" or "ann-JY-nuh") is a type of chest pain or discomfort that occurs when there is not enough blood flow to the heart. Angina can be dangerous, so it is important to pay attention to chest pain, know what is typical for you, learn how to control it, and understand when you need to get treatment. There are two types of angina: Stable angina is chest pain that has a typical pattern. It happens when your heart is working harder and needs more oxygen, such as during exercise. ...

We should exclude this patient because the patient's "HIGH RISK" status has diminished after CABG. Q. Multi-vessel CABG (2000), recurrent angina resulting in PCI of LIMA graft at insertion site to LAD (2001), negative stress test post PCI. Eligible? (which of these events do we count, the CABG or the PCI) A: Not eligible. After the PCI the stress test is negative, therefore, this becomes a low risk patient. Check for disease elsewhere.
