Chest pain, clinically known as angina, is a significant symptom indicating that the heart muscle isn’t receiving sufficient oxygen. It’s crucial to understand that chest pain itself isn’t a disease but a manifestation of an underlying medical condition. Prompt and accurate diagnosis is vital to address the root cause and prevent serious complications.
The sensation of chest pain can vary widely, described as squeezing, dull, sharp, crushing, or burning. Patients experiencing severe angina may report an intense pressure, often likened to a heavy weight pressing on their chest. This pain can radiate beyond the chest, extending to the neck, jaw, or down the arms. Recognizing these diverse presentations of chest pain is the first step in effective nursing care.
Decoding Chest Pain: Types and Underlying Causes
Chest pain is often a symptom of various underlying health issues, including:
- Coronary Artery Disease (CAD): The most common cause, CAD involves the narrowing or blockage of coronary arteries, reducing blood flow to the heart.
- Coronary Microvascular Disease (MVD): Affecting the small blood vessels of the heart, MVD can also lead to angina.
- Pleuritis: Inflammation of the lining around the lungs, which can cause sharp chest pain that worsens with breathing.
- Pulmonary Embolism (PE): A life-threatening condition where a blood clot blocks an artery in the lungs, causing sudden chest pain and shortness of breath.
- Pneumothorax: Occurs when air leaks into the space between the lungs and chest wall, leading to lung collapse and chest pain.
- Gastroesophageal Reflux Disease (GERD): Stomach acid refluxing into the esophagus can cause heartburn, which is sometimes mistaken for chest pain.
Within angina itself, there are distinct types, each with unique characteristics:
-
Stable Angina (Angina Pectoris): This predictable form of chest pain is typically triggered by physical exertion or emotional stress. It arises from CAD, where narrowed arteries restrict blood flow during increased demand. Stable angina usually subsides with rest or medication, such as nitroglycerin. Recognizing the triggers and predictable nature is key in managing stable angina.
-
Unstable Angina: This is a more serious and unpredictable type of chest pain. It often occurs at rest and is a sign of a higher risk of myocardial infarction (heart attack). Unstable angina is frequently caused by the rupture of plaque in a coronary artery, leading to a sudden reduction in blood flow. It requires immediate medical attention and intervention to prevent severe cardiac events.
-
Variant (Prinzmetal) Angina: This less common type of angina is characterized by chest pain due to coronary artery spasm, temporarily narrowing the artery. It often occurs at rest, typically between midnight and early morning. Understanding this vasospastic mechanism is important for targeted treatment strategies.

Identifying Risk Factors for Chest Pain
Several factors increase an individual’s likelihood of experiencing angina. Recognizing these risk factors is essential for preventative care and patient education:
- High Cholesterol: Elevated levels of LDL cholesterol contribute to plaque buildup in arteries, narrowing them and increasing the risk of angina and CAD.
- Hypertension: High blood pressure puts extra strain on the heart and arteries, accelerating the development of atherosclerosis and angina.
- Smoking: Smoking damages blood vessels, promotes plaque formation, and reduces the oxygen-carrying capacity of blood, significantly increasing the risk of angina and heart disease.
- Overweight or Obesity: Excess body weight is linked to several risk factors for angina, including high cholesterol, hypertension, and diabetes.
- Diabetes: Diabetes mellitus increases the risk of heart disease and angina by damaging blood vessels and nerves.
- Metabolic Syndrome: A cluster of conditions including increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels, significantly raising the risk of heart disease and angina.
- Sedentary Lifestyle: Lack of physical activity contributes to obesity, high cholesterol, and hypertension, all of which are risk factors for angina.
- Unhealthy Diet: Diets high in saturated and trans fats, cholesterol, and sodium can lead to high cholesterol, hypertension, and obesity, increasing angina risk.
- Family History of Heart Disease: A family history of early heart disease increases an individual’s genetic predisposition to developing angina and related conditions.
- Older Age: The risk of angina and heart disease increases with age, particularly for men over 45 and women over 55.
Prompt diagnosis and treatment of chest pain are crucial to prevent serious consequences like myocardial infarction (heart attack). A thorough physical assessment coupled with risk factor identification is paramount. Diagnostic tests play a vital role in confirming the underlying cause of chest pain and guiding appropriate treatment. These tests may include:
- Electrocardiogram (ECG): To assess the heart’s electrical activity and detect signs of heart damage or ischemia.
- Blood Tests: To measure cardiac enzymes (like troponin) that are released into the bloodstream during heart muscle damage, as well as assess cholesterol levels and other risk factors.
- Stress Tests: To evaluate how the heart functions during physical exertion, helping to identify ischemia that may not be apparent at rest.
- Coronary Angiography: An invasive procedure that uses dye and X-rays to visualize the coronary arteries and identify blockages.
- Chest X-ray: To visualize the lungs and heart, helping to rule out other causes of chest pain like pneumonia or pneumothorax.
- Cardiac Catheterization: A procedure to assess heart function and blood flow, often combined with coronary angiography.
- Computed Tomography Angiography (CTA): A non-invasive imaging technique to visualize coronary arteries and detect blockages.
The Nurse’s Role: Nursing Process and Chest Pain Management
Nurses are integral in the comprehensive management of patients experiencing chest pain. A detailed pain assessment is the cornerstone of nursing care, facilitating timely diagnosis and intervention.
The primary goals of nursing care for patients with chest pain are:
- Accurate Identification: To determine the specific type of angina and its underlying cause.
- Prompt and Appropriate Treatment: To initiate timely interventions to alleviate pain and address the underlying condition.
- Pain Relief and Vasodilation: To administer medications that relieve pain and improve blood flow to the heart muscle.
- Myocardial Preservation: To take immediate steps to protect heart muscle if myocardial infarction is suspected.
- Lifestyle Modification Education: To educate patients on lifestyle changes that reduce their risk factors and prevent future episodes.
Patient education is a critical component of nursing care. Patients need to be empowered to recognize the symptoms of stable versus unstable angina, understand their treatment plan, and know when to seek immediate emergency assistance.
Nursing Care Plans for Acute Chest Pain
Once nursing diagnoses are established, nursing care plans provide a structured framework for prioritizing assessments and interventions, guiding both short-term and long-term care goals. Here are examples of nursing care plans relevant to acute chest pain:
Acute Pain
Chest pain is a subjective experience described variably by patients – squeezing, tight, sharp, or dull. It can sometimes mimic indigestion, presenting as a burning sensation. The hallmark description is often pressure, a feeling of “an elephant sitting on my chest.”
Nursing Diagnosis: Acute Pain
Related to:
- Myocardial injury
- Ischemia
- Disease process
- Physical exertion
As evidenced by:
- Diaphoresis (sweating)
- Distraction behaviors (e.g., pacing, restlessness)
- Verbal reports of chest pain, pressure, tightness
- Facial grimacing or expression of pain
- Guarding behavior (protecting the chest area)
- Positioning to ease pain (e.g., leaning forward)
- Clutching of chest
- Tachycardia (increased heart rate)
Expected Outcomes:
- Patient will report a reduction in chest pain to a tolerable level within a specified timeframe (e.g., within 30 minutes of intervention).
- Patient will be able to identify factors that exacerbate or relieve their chest pain.
Nursing Assessments:
-
Assess Pain Characteristics: Detailed assessment is crucial. Note the onset, location (e.g., substernal, radiating), quality (e.g., sharp, dull, pressure), intensity (using a pain scale), aggravating and alleviating factors, and duration of the pain. This comprehensive pain assessment guides accurate diagnosis and tailored management.
-
Review Diagnostic Test Results: Pay close attention to results of ECG, cardiac enzyme levels, and other relevant tests. A 12-lead ECG is typically performed immediately for patients presenting with chest pain to rapidly detect or rule out myocardial infarction.
-
Elicit History of Chest Pain: Determine if the patient has a history of angina or similar chest pain episodes. Comparing the current pain episode to previous experiences helps differentiate between stable and unstable angina and guides treatment decisions.
Nursing Interventions:
-
Administer Pain Medications as Prescribed: Follow physician orders for analgesics, nitrates, and other cardiac medications. Pharmacological therapy aims to provide prompt pain relief, improve myocardial perfusion, and reduce the risk of myocardial infarction. Short-acting nitrates like nitroglycerin are commonly used for immediate relief, while ACE inhibitors, analgesics, and calcium channel blockers may be used for longer-term management.
-
Provide Oxygen Supplementation: Administer supplemental oxygen as indicated by oxygen saturation levels and patient condition. Oxygen therapy increases oxygen delivery to the myocardium, especially critical during ischemic episodes. However, if oxygen saturation is within normal limits, supplemental oxygen may not be routinely necessary.
-
Prepare for Further Diagnostic Testing: Facilitate and prepare the patient for stress tests, echocardiograms, CTAs, or cardiac catheterization as ordered. These advanced tests provide detailed information about cardiac function and coronary artery anatomy, guiding further treatment strategies, including identifying potential blockages.
-
Provide Patient Education on Pain Management: Educate the patient about their specific type of angina, medication regimen (including proper administration of nitroglycerin), symptom recognition, and when to seek emergency medical attention. Empowering patients with knowledge promotes self-management and timely intervention for future episodes.

Anxiety
The experience of chest pain, particularly when severe or unexpected, can trigger significant fear and anxiety in patients.
Nursing Diagnosis: Anxiety
Related to:
- Perceived threat of death or serious illness
- Unfamiliar hospital environment and procedures
- Threat to current health status and lifestyle
As evidenced by:
- Verbalization of alarm or worry
- Expressing fear or apprehension
- Reporting panic or feelings of unease
- Nausea
- Dry mouth
- Palpitations (awareness of rapid or irregular heartbeat)
- Difficulty concentrating or focusing
- Tachycardia
- Tachypnea (rapid breathing)
- Diaphoresis
Expected Outcomes:
- Patient will verbalize effective coping strategies to manage anxiety related to chest pain and its potential implications.
- Patient will report a subjective sense of decreased fear and increased feelings of safety and control.
Nursing Assessments:
- Assess Patient’s Feelings of Fear and Anxiety: Engage in open communication with the patient to explore their specific thoughts and feelings about their chest pain and its potential significance. Actively listening to and validating the patient’s concerns is the first step in alleviating unnecessary anxiety and providing emotional support.
Nursing Interventions:
-
Provide Verbal and Physical Reassurance: Offer consistent verbal reassurance about their safety and the care being provided. Non-verbal comfort, such as a gentle touch (if appropriate and culturally sensitive), holding their hand, or calmly rubbing their back, can be highly effective. Providing both verbal and physical support while the patient expresses their fears and emotions can significantly reduce anxiety levels.
-
Explore Positive Coping Mechanisms: Teach and encourage the patient to utilize relaxation techniques and positive coping strategies. Chest pain, dyspnea, and related symptoms can be alarming. Educating patients on techniques like deep breathing exercises, guided imagery, or distraction methods can empower them to manage anxiety.
-
Administer Anti-Anxiety Medications as Ordered: If anxiety is severe or debilitating, administer prescribed anxiolytic medications, such as benzodiazepines, as appropriate and ordered by the physician. Severe anxiety can negatively impact physiological parameters and worsen outcomes. Medications may be necessary to promote relaxation and reduce fear in certain situations.
-
Provide Knowledge and Education: Once the acute threat has subsided and the patient is receptive, provide clear and understandable information about their chest pain, its causes, treatment plan, and prognosis. Knowledge is a powerful tool against anxiety. A patient who understands their condition and treatment is likely to feel more in control and experience less fear and anxiety.
Decreased Cardiac Output
Reduced cardiac output occurs when the heart is unable to pump sufficient blood to meet the body’s needs, often due to underlying cardiac conditions associated with chest pain.
Nursing Diagnosis: Decreased Cardiac Output
Related to:
- Ineffective myocardial contraction (reduced pumping strength of the heart muscle)
- Conditions compromising blood supply to the heart (e.g., CAD, MI)
- Narrowed or blocked arteries
- Rupture of unstable plaque
- Coronary vasospasm
- Structural heart defects
- Impaired heart muscle function
As evidenced by:
- Increased central venous pressure (CVP)
- Tachycardia or bradycardia (abnormally fast or slow heart rate)
- Dysrhythmias (irregular heart rhythms)
- Ejection fraction less than 40% (indicating reduced pumping efficiency)
- Decreased oxygen saturation (SpO2)
- Presence of abnormal heart sounds (e.g., S3, S4)
- Chest pain (angina)
- Hypotension or hypertension (abnormally low or high blood pressure)
- Dyspnea
- Tachypnea
- Changes in level of consciousness (e.g., confusion, restlessness)
- Fatigue, weakness
- Activity intolerance
- Cool, clammy skin
- Prolonged capillary refill time
- Edema (peripheral or pulmonary)
Expected Outcomes:
- Patient will demonstrate adequate cardiac output as evidenced by stable vital signs (heart rate, blood pressure within acceptable limits), normal sinus rhythm on ECG, and improved perfusion (warm and dry skin, adequate urine output).
- Patient will report reduced symptoms of decreased cardiac output such as dyspnea, fatigue, and chest pain.
Nursing Assessments:
-
Assess for Signs and Symptoms of Decreased Cardiac Output: Monitor for a constellation of symptoms that may accompany chest pain and indicate reduced cardiac output and systemic perfusion. These signs and symptoms can include diaphoresis, dyspnea, cough, nausea and vomiting, abdominal pain, fever, edema, calf pain, and swelling in the lower extremities. Recognizing these associated symptoms is crucial for timely intervention.
-
Monitor Heart Rate and Rhythm: Continuously assess heart rate and rhythm. Tachycardia is often an initial compensatory mechanism as the heart attempts to maintain cardiac output during angina episodes.
-
Obtain and Monitor ECG: Regular ECG monitoring is essential. ECG changes such as ST-segment elevation, ST-segment depression, T-wave inversions, or new onset arrhythmias (e.g., atrial fibrillation, tachycardic rhythms) are critical indicators of myocardial ischemia or injury and guide further diagnostic and therapeutic interventions.
-
Review Laboratory Results: Assess relevant lab values. A complete blood count (CBC) can identify conditions like anemia or infection. A basic metabolic panel (BMP) assesses electrolyte balance and kidney function, which can be affected by reduced cardiac output and medications.
Nursing Interventions:
-
Treat the Underlying Cause: Address the root cause of decreased cardiac output. Chest pain and reduced cardiac output can stem from various cardiac and non-cardiac factors. Identifying and treating the underlying cause is paramount. Non-cardiac causes may include pulmonary conditions, musculoskeletal issues, anxiety, or GERD. Cardiac causes can range from pericardial disease (non-ischemic) to coronary artery atherosclerosis and myocardial infarction (ischemic).
-
Implement Risk Factor Management: Focus on managing modifiable risk factors for heart disease. Controlling blood pressure, cholesterol levels, and blood glucose is crucial. Educate patients on medication adherence and lifestyle modifications to mitigate their individual risk profiles.
-
Encourage Lifestyle Modifications: Promote patient participation in and adherence to heart-healthy lifestyle changes. Lifestyle modifications are fundamental to long-term cardiac health, reducing plaque buildup and improving blood vessel function. Emphasize regular exercise, maintaining a healthy weight, smoking cessation, and a heart-healthy diet.
-
Administer Medications as Prescribed: Administer cardiac medications as ordered, such as antianginals (e.g., nitroglycerin), beta-blockers, calcium channel blockers, ACE inhibitors, and diuretics. Antianginal medications like nitroglycerin provide immediate symptom relief. The overall goal of pharmacotherapy is to reduce myocardial oxygen demand and improve cardiac function.
-
Control Heart Rate: Utilize medications to manage heart rate as appropriate. Certain antianginal medications, such as beta-blockers, ivabradine, and non-dihydropyridine calcium channel blockers, reduce heart rate to decrease myocardial oxygen demand and alleviate angina symptoms. Note contraindications, such as avoiding calcium channel blockers in patients with low ejection fraction and left ventricular failure.
Risk for Decreased Cardiac Tissue Perfusion
Chest pain itself is a significant indicator of potential or actual decreased cardiac tissue perfusion, raising the risk for myocardial infarction and other serious cardiac events.
Nursing Diagnosis: Risk for Ineffective Tissue Perfusion (Cardiac)
Related to:
- Heart disease (e.g., CAD, atherosclerosis)
- Hypoxia
- Myocardial infarction
- Ischemia
- Hypoxemia
As evidenced by:
A risk diagnosis is not evidenced by existing signs and symptoms as the problem has not yet occurred. Nursing interventions are focused on prevention.
Expected Outcomes:
- Patient will maintain adequate cardiac tissue perfusion as evidenced by absence of chest pain, stable vital signs, and appropriate hemodynamic parameters.
- Patient will demonstrate understanding of risk factors for decreased cardiac tissue perfusion and implement preventative measures.
- Patient will not experience a myocardial infarction or other adverse cardiac event.
Nursing Assessments:
-
Assess for Symptoms and Risk Factors: Continuously assess for symptoms suggestive of impaired cardiac tissue perfusion, particularly in patients with risk factors for heart disease. Symptoms such as chest pain, shortness of breath, diaphoresis, indigestion, and anxiety can indicate compromised cardiac perfusion. Identify and document existing risk factors for heart disease.
-
Obtain and Monitor Laboratory Work: Regularly monitor cardiac enzyme levels (e.g., troponin), electrolytes, arterial blood gases (ABGs), and other relevant blood tests. Cardiac enzymes are critical indicators of myocardial damage. Electrolyte imbalances and ABG abnormalities can reflect or exacerbate cardiac issues.
-
Continuously Monitor Telemetry: Implement continuous telemetry monitoring of vital signs, including blood pressure, pulse rate, ECG, and oxygen saturation. Continuous monitoring allows for the early detection of changes indicative of decreased cardiac perfusion, such as arrhythmias, ST-segment changes, or hemodynamic instability.
Nursing Interventions:
-
Reduce Cardiac Workload: Implement measures to reduce the heart’s oxygen demand. Administer supplemental oxygen to improve oxygenation. Encourage bed rest or activity restriction to minimize oxygen consumption and cardiac workload.
-
Prepare for Potential Surgical Interventions: Be prepared to facilitate and assist with potential surgical or interventional procedures. Cardiac catheterization with percutaneous coronary intervention (PCI), including stent placement, may be necessary to open blocked coronary arteries. Coronary artery bypass graft (CABG) surgery may be required in more complex cases to revascularize the heart.
-
Administer Medications as Prescribed: Administer cardiac medications as ordered, including vasodilators, anticoagulants, digoxin, and antihypertensives. Vasodilators relax blood vessels, improving blood flow. Anticoagulants prevent blood clot formation. Digoxin can improve cardiac contractility. Antihypertensives manage blood pressure.
-
Educate Patient on Lifestyle Modifications for Risk Reduction: Provide comprehensive education on lifestyle modifications to reduce the risk of decreased cardiac tissue perfusion and future cardiac events. Emphasize the importance of a heart-healthy diet (low in sodium and saturated/trans fats), smoking cessation, regular physical activity, and weight management.
Risk for Unstable Blood Pressure
Chest pain and associated cardiac conditions can lead to fluctuations in blood pressure, increasing the risk for both hypotension and hypertension.
Nursing Diagnosis: Risk for Unstable Blood Pressure
Related to:
- Ineffective myocardial contraction
- Conditions compromising cardiac blood supply
- Narrowed or blocked arteries
- Rupture of unstable plaque
- Coronary vasospasm
- Structural heart defects
- Increased cardiac workload
- Dysrhythmias
- Electrolyte imbalances
- Fluid volume imbalances (retention or deficit)
As evidenced by:
A risk diagnosis is not evidenced by existing signs and symptoms as the problem has not yet occurred. Nursing interventions are aimed at prevention.
Expected Outcomes:
- Patient will maintain blood pressure within individually acceptable limits as defined by physician orders and patient baseline.
- Patient will remain free from orthostatic hypotension and associated symptoms (e.g., dizziness, lightheadedness) when changing positions.
- Patient will verbalize understanding of when to contact their healthcare provider regarding hypo- or hypertension and blood pressure management.
Nursing Assessments:
-
Routinely Monitor Blood Pressure: Assess blood pressure frequently and at prescribed intervals. In unstable angina, oxygen demand may increase even at rest, while in stable angina, it typically increases with exertion. Exercise-induced increases in heart rate, blood pressure, and myocardial contractility contribute to increased myocardial oxygen demand.
-
Assess for Subjective Symptoms: Inquire about symptoms that may indicate blood pressure instability. Ask if the patient experiences palpitations, headaches, lightheadedness, or dizziness. These symptoms can be indicative of hypo- or hypertension.
-
Review Medication History: Thoroughly review the patient’s current medication list, including over-the-counter drugs and herbal supplements. Polypharmacy, particularly in older adults, increases the risk of blood pressure instability. Multiple antihypertensive medications, diuretics, antidepressants, and herbal remedies can interact and affect blood pressure control.
Nursing Interventions:
-
Prevent Excessive Exertion: Advise patients to avoid activities that may exacerbate angina and blood pressure instability. Angina can manifest as chest pressure, squeezing, soreness, or fullness during activities like strenuous exercise, walking uphill, or climbing stairs, especially in patients with hypertension.
-
Educate on Recognizing and Responding to Blood Pressure Changes: Educate the patient on what constitutes uncontrolled blood pressure (both high and low) and when to seek medical help. Patients may not be aware of appropriate blood pressure ranges or when readings are concerning. Instruct them on regular blood pressure monitoring and provide specific guidelines on blood pressure values that require immediate medical attention.
-
Promote Lifestyle Modifications for Blood Pressure Control: Reinforce the importance of lifestyle modifications to manage blood pressure. Simple lifestyle changes can significantly impact blood pressure. Emphasize dietary sodium reduction, regular exercise, weight management, limiting alcohol intake, and smoking cessation.
-
Strategize to Enhance Blood Pressure Control and Medication Adherence: Implement strategies to improve patient adherence to blood pressure management plans. Nurses play a vital role in monitoring, evaluating, and supporting patient participation in blood pressure control. Strategies to improve adherence include providing clear and concise instructions in understandable language, simplifying medication regimens (e.g., once-daily dosing), encouraging self-monitoring, and providing educational materials promoting overall health.
