Study Notes
Angina
- Characterized by chest pain caused by reduced blood flow to the heart muscle
- Typically described as a tight, squeezing, constricting, or heavy sensation
- Can also be described as burning, aching, choking, dull, or constant
- Often lasts for 2-5 minutes
- Relieved by rest, position change, or nitroglycerin
Acute Coronary Syndrome (ACS)
- Umbrella term encompassing a spectrum of conditions related to unstable coronary plaques
- Includes unstable angina and myocardial infarction (heart attack)
Acute Myocardial Infarction (MI)
- Characterized by a complete blockage of blood flow to the heart muscle
- Can cause irreversible heart damage if not treated promptly
- Typically results from a ruptured atherosclerotic plaque
-
Symptoms
- Crushing, severe tightness or burning in the chest
- Heavy pressure or squeezing sensation
- Can radiate to the shoulders, neck, jaw, or arms
- Often lasts for more than 15-20 minutes
-
Often associated with:
- Dyspnea
- Diaphoresis
- Cool, mottled skin
- Tachycardia
- Hypotension or hypertension
- Nausea and vomiting
- Anxiety and a sense of impending doom
- Decreased level of consciousness
Precipitating Factors
- Angina: Exercise or activity, strong emotion, stress, cold, or heavy meal
- ACS: Generally unknown; ruptured atherosclerotic plaque plays a role
- MI: Generally unknown; ruptured atherosclerotic plaque plays a role
Relieving Factors
- Angina: Rest, position change, or nitroglycerin
- ACS: None; must treat underlying event
- MI: None; must treat underlying event
Location of Pain
- Angina: Substernal or precordial (across the chest wall)
- ACS: Substernal or epigastric chest pain
- MI: Starts in the center of the chest (substernal) and can radiate to the shoulders, neck, jaw, or arms
Length of Pain
- Angina: 2–5 minutes
- ACS: At least 10–20 minutes
- MI: More than 15–20 minutes
Angina
- Chest pain that occurs when the heart muscle doesn't get enough oxygen.
- Often described as tightness, squeezing, constricting, or heavy sensation.
- May also be described as burning, aching, choking, dull, or constant.
- Usually lasts for 2–5 minutes.
- Relieved by rest, position change, or nitroglycerin.
Acute Coronary Syndrome (ACS)
- Umbrella term for a range of conditions caused by a sudden blockage of a coronary artery.
- Includes unstable angina, NSTEMI, and STEMI.
- Chest pain may be new onset or represent a pattern of increasing frequency and severity of anginal pain.
- Can be caused by exertion or stress, but often the cause is unknown.
Acute Myocardial Infarction (AMI)
- Heart attack.
- Occurs when there is a complete blockage of a coronary artery leading to death of heart muscle.
- Often starts in the center of the chest and radiates to the shoulders, neck, jaw, or arms.
- Lasts more than 15–20 minutes.
- Characterized by intense crushing, tightness, or burning pain, severe pressure, or a squeezing sensation that is more severe than angina pain.
- Associated with symptoms like nausea, vomiting, dyspnea, diaphoresis, anxiety, palpitations, and irregular heart rhythms.
- Requires immediate medical attention.
Angina
- The most prominent symptom of angina is chest pain.
- Angina pain can be triggered by physical activity, strong emotions, stress, heavy meals, or exposure to cold.
- The classic pattern of angina is pain during activity and relief during rest.
- Angina pain can manifest as tightness, squeezing, heavy pressure, or a constricting sensation in the chest.
- The pain can radiate to the jaw, neck, shoulder, or arm.
- In some cases, angina pain can also be felt in the jaw, epigastric region, or back.
- Men typically experience more characteristic patterns of angina pain.
- Women frequently present with atypical symptoms, including indigestion, nausea, vomiting, fatigue, and upper back pain.
- Anginal pain usually follows a crescendo-decrescendo pattern, increasing to a peak, then gradually decreasing.
- Anginal pain typically lasts 2 to 5 minutes and is usually relieved by rest.
- Other symptoms of angina can include shortness of breath, pallor, rapid heart rate, anxiety, and fear.
- The severity of angina is categorized into classes that reflect its impact on physical activity:
- Class I Angina: Mildest class, occurring with strenuous or prolonged exertion.
- Class II Angina: Develops with rapid or prolonged walking or stair climbing.
- Class III Angina: Significantly limits ordinary physical activities.
- Class IV Angina: Most severe, occurring with minimal exertion or at rest.
Acute Coronary Syndrome (ACS)
- The primary symptom of ACS is substernal or epigastric chest pain.
- The pain can radiate to the neck, left shoulder, and/or left arm.
- Pain can occur with rest or activity and typically lasts at least 10 to 20 minutes.
- ACS can manifest as new onset pain or an increase in frequency and severity of anginal pain.
- Other symptoms include shortness of breath, sweating, paleness, cool skin, rapid heart rate, and low blood pressure.
- Nausea or dizziness can also occur.
Acute Myocardial Infarction (AMI)
- Chest pain that is more severe than previously experienced angina is the most common symptom of AMI.
- This pain has a sudden onset, is not usually associated with activity, and is continuous in nature.
- AMI typically occurs in the early morning.
- Individuals with a history of angina may experience escalating angina events leading up to an AMI.
- Chest pain associated with AMI is often described as crushing, severe, tightness or burning, heavy pressure, or a squeezing sensation.
- The pain can start in the center of the chest (substernal) and may radiate to the shoulders, neck, jaw, or arms.
- The duration of pain is typically longer than 15-20 minutes and is not relieved by rest or nitroglycerin.
- Other symptoms can develop due to the loss of myocardial oxygenation, including:
- Anxiety, rapid heart rate, and vasoconstriction: Caused by the sympathetic nervous system stimulation.
- Rapid breathing: Triggered by pain and blood chemistry imbalances.
- Elevated temperature and increased white blood cell count: Reflect the inflammatory reaction to tissue necrosis.
- Release of cardiac enzymes: Caused by injured or necrotic myocardial cells.
- The location and extent of the infarction can influence additional symptoms like high or low blood pressure, or heart failure.
- Nausea, vomiting, slow heart rate, and low blood pressure can manifest from vagal stimulation.
- Diaphragmatic irritation can cause hiccups.
- Sudden death can occur if a large vessel is occluded.
- Individuals experiencing chest pain for the first time may attribute it to indigestion.
- It is crucial for healthcare providers to emphasize the potential implications of chest pain to promote prompt emergency medical service (EMS) activation.
- Immediate emergency department (ED) evaluation is essential if thrombolytic medications are being considered.
- The risk of complications following AMI is dependent on the size and location of the affected area.
- Potential complications include:
- Irregular heartbeats (dysrhythmias)
- Heart failure (pump failure)
- Cardiogenic shock
- Infarct extension
- Structural defects
- Pericarditis
- Dressler syndrome
