Chronic stable angina history and symptoms On the Web
The name 'angina pain' can be thought of as a misnomer as patients often describes the sensation as discomfort rather than physical pain. The best method to characterize this discomfort/pain is through the 'PQRST system'.
History and Symptoms
- The most common cause of anginal pain is exertion. Anginal discomfort is often relieved by rest or nitroglycerine. Usually relief from rest or nitroglycerine occurs in 2 to 3 minutes.
- Less common precipitants of anginal discomfort include:
- The discomfort is not precipitated by changes in position. This is in contrast to pericarditis which is relieved by sitting up or sitting forward.
- In following the patient with chronic stable angina, the duration and or distance of exertion required to provoke the angina should be recorded to monitor the response to therapy.
Stable angina can be classified basing upon features.
- Substernal chest pain.
- Pain provocated by exertion and/or emotional stress.
- Relieved with rest and/or nitroglycerin.
Typical angina - All the three features. Atypical angina - two features. Non-anginal chest pain - one feature.
- The nature of the sensation is usually not described as a "pain" but rather as a discomfort. It is often described as:
- A sense of heaviness
- Band like tightness
- Or even as an "elephant sitting on my chest"
- The pain is not sharp or pleuritic in nature. This is in contrast pericarditis which is described in this way.
- Typically the angina is located in the center of the chest or on the left side of the chest.
- Less frequently the discomfort is predominantly in the epigastrum, the shoulders, neck or jaw.
- In some patients, the pain may radiate to the inner aspect of the left arm, the neck or the jaw.
Severity Scale (S)
- The patient should be asked to rank their pain on a scale of 0 - 10, zero being no pain at all and 10 being the worst pain ever.
- The patient should be asked:
- Does the discomfort interferes with activities?
- How bad the discomfort is when it is at its worst?
- Does it force the patient to sit down, lie down, or slow down?
- Both the New York Heart Association functional classification scheme (NYHA) and the Canadian Cardiovascular Society functional classification (CCS) can be used to quantify the severity of anginal pain.
- Anginal discomfort usually lasts 1 to 5 minutes with a range from 1 minute to 30 minutes. Pain that lasts seconds is usually not anginal pain.
- The pain is usually relieved in 2 to 3 minutes with rest or nitroglycerine. Anginal discomfort associated with emotional distress is usually relieved more slowly.
- Angina that occurs at night (nocturnal angina) is characteristic of coronary spasm.
- In following the patient with angina, the frequency and duration of pain, should be recorded to assess the response to therapy.
- There may be symptoms of systolic or diastolic left ventricular dysfunction that leads to shortness or breath or dyspnea.
- In some patients, chest discomfort is not present, and dyspnea is the anginal equivalent.

ACC/AHA/ACP–ASIM Guidelines for the Management of Patients With Chronic Stable Angina (DO NOT EDIT)
Clinical Evaluation of Patients With Chest Pain (DO NOT EDIT)
Clinical Evaluation in the Initial Diagnosis of SIHD in Patients With Chest Pain
"1. Patients with chest pain should receive a thorough history and physical examination to assess the probability of IHD before additional testing.(Level of Evidence:C)"
"2. Patients who present with acute angina should be categorized as stable or unstable; patients with UA should be further categorized as being at high, moderate, or low risk.(Level of Evidence:C)"
ESC Guidelines- Clinical Evaluation (DO NOT EDIT)
|"1. Detailed clinical history and physical examination including BMI and/or waist circumference in all patients, also including a full description of symptoms, quantification of functional impairment, past medical history, and cardiovascular risk profile. (Level of Evidence: B)"|
|"2. Resting ECG in all patients. (Level of Evidence: B)"|
