Types of Angina
Angina can be classified into the following five
types:
1. Stable Angina
2. Unstable Angina
3. Variant or Prinzmetal’s Angina
4. Microvascular Angina
5. Atypical Angina
Stable Angina:
This is the most common type occurring due to physical
exertion such as walking up stairs, running to catch a
bus, mental or emotional stress and physical exercise
that cause strain with the pain being predictable. The
stable angina follows a regular pattern and the
pain/discomfort subsides on taking rest but returns on
resumption of the activity.
Unstable Angina:
The chest pain is unexpected and occurs with little
physical effort or when the patient is at rest and the
pain may be severe, prolonged and more frequent as
compared to stable angina. Sometimes, stable angina can
progress to unstable angina or an unstable angina can
also develop from inflammation, infection, abnormal
constriction of artery or partial blockade of artery due
to blood clot. Unstable angina does not follow a regular
pattern and can prove to be fatal requiring immediate
attention.
Variant Angina or Prinzmetal’s Angina:
This is a very uncommon type affecting women more often
than men between midnight to early morning hours (8.00 AM
in the morning). In this type, normal symptoms of angina
occur but with severity and for a prolonged period. The
pain does not follow severe physical exertion or mental
strain (3) & (5).
Microvascular Angina:
In this type, chest pain occurs but without any blockage
in a coronary artery. The pain is due to improper
functioning of the tiny arteries supplying blood to
heart. This condition is referred to as Syndrome X.
Atypical Angina:
Typical symptoms of angina may not be experienced in this
type and the patient may experience a mild chest
discomfort, shortness of breath, fatigue, nausea, back or
neck pain or burning indigestion. Women are more prone to
experience symptoms of atypical angina (6).
