Stable angina differs from unstable angina in terms of attack triggers, duration, and severity.
1. Attack triggers. Stable angina usually occurs during physical labor or emotional excitement, while unstable angina can occur in a quiet state.
2. Duration. Stable angina is usually relieved by resting or taking nitroglycerin for a few minutes, while unstable angina lasts for a longer period of time, up to 20-30 minutes.
3. Severity. The severity of unstable angina is relatively serious and is accompanied by many symptoms, such as palpitations, sweating, nausea, vomiting and tightness of breath.
When angina occurs, it is necessary to consult a doctor in a timely manner, under the guidance of the doctor’s regular use of medication, and if necessary, coronary angiography to clarify.
