Is irregular angina dangerous?

Irregular angina is generally dangerous.

Irregular angina is usually more dangerous than stable angina because its symptoms are more unpredictable in frequency and duration and can lead to serious health complications such as myocardial infarction, heart failure or sudden cardiac death. In addition, irregular angina may affect the daily life of the patient and lead to a decrease in quality of life.

To reduce the risk of irregular angina, patients should actively receive treatment, including medication, intervention or surgery. Good habits such as quitting smoking, limiting alcohol consumption, weight control, and increasing exercise should also be developed in daily life.
