Chest Pain (Angina) Nursing Care Plan and Diagnosis

Angina is myocardial ischemia talking. It is not its own disease, it is the chest telling you the heart muscle is not getting enough oxygen, usually from coronary artery disease. Your job at the bedside is to read the pain fast, relieve it, cut oxygen demand, and catch the patient who is sliding from stable angina toward infarction.

What Is Angina

Angina pectoris is chest pain from myocardial ischemia, caused by blockage or spasm of a coronary artery and a drop in myocardial blood supply. The lack of oxygen is felt as discomfort, pressure, or pain. It can show up anywhere in the chest, neck, arms, or back, but the classic location is pressure behind the sternum, often radiating to the left arm, and sometimes to both arms, the back, shoulder, jaw, or neck.

Angina comes in three forms:

• Stable angina is predictable chest pain on exertion, tied to stable plaque in the coronary arteries.
• Variant (Prinzmetal's) angina is less common. Episodes occur at rest, driven by coronary vasospasm, and can produce a transient ST-segment elevation.
• Unstable angina is pain that comes more often and unpredictably, at rest or with minimal exertion. It is the one that gets the patient to limit activity, and it is the one that can kill.

Most angina traces back to coronary artery disease. Plaque (fat, cholesterol, calcium, and other blood-borne substances) builds inside the coronary arteries, narrows them, and drops blood flow to the heart. It also makes clots more likely. Partial or complete blockage starves the myocardium of oxygen, which drives angina or a heart attack. Without quick treatment, an MI can become catastrophic.

Nursing Care Plan and Management

Care for angina is prompt assessment, effective pain control, and tight vital sign monitoring so you intervene before damage is done.

Nursing Problem Priorities

1. Manage the chest pain and relieve it.
2. Prevent complications (MI, cardiac arrest, cardiogenic shock).
3. Decrease oxygen demand by balancing activity and rest.
4. Reduce anxiety and fear.
5. Teach the patient about the disease, self-care, and lifestyle change.

Nursing Assessment

Assess for the following subjective and objective data:

• Pain that varies in frequency, duration, and intensity, especially as the condition worsens
• Narrowed focus
• Distraction behaviors (moaning, crying, pacing, restlessness)
• Autonomic responses (diaphoresis, blood pressure and pulse changes, pupillary dilation, increased or decreased respiratory rate)
• Situational crisis and reports of anxiety

Assess for factors driving the pain:

• Decreased myocardial blood flow
• Increased cardiac workload and oxygen consumption
• Myocardial tissue ischemia

Nursing Diagnosis

Formulate the diagnosis from your assessment and clinical judgment of the patient's condition. Diagnostic labels are a framework, not the point. In practice, your judgment shapes the plan around the patient's actual priorities.

Nursing Goals

• The client will report anginal episodes decreased in frequency, duration, and severity.
• The client will demonstrate relief of pain, shown by stable vital signs and absence of muscle tension and restlessness.
• The client will verbalize understanding of the disease process, the treatment regimen, and potential complications.
• The client will start the lifestyle changes needed to prevent myocardial complications.

Nursing Interventions and Actions

1. Managing acute chest pain and discomfort
2. Administering medications and pharmacologic interventions
3. Decreasing oxygen demand and managing decreased cardiac output
4. Monitoring and preventing myocardial complications
5. Providing emotional support and reducing anxiety
6. Patient education for lifestyle change

1. Managing Acute Chest Pain and Discomfort

Ischemia happens when oxygen demand outstrips supply, leading to tissue damage and possible thrombus formation. Assess and intervene as follows.

1. Perform a pain assessment: identify precipitating events, frequency, duration, intensity, and location. This differentiates the pain and tracks any progression to unstable angina. The shift from stable to unstable angina is potentially life-threatening.

2. Assess and document the response to medication. This shows disease progression and the effectiveness of your interventions, and may signal a need to change the regimen. Microvascular spasm is often unresponsive to short-acting nitrates and hard to treat, and it can only be told apart from other angina during invasive provocation testing.

3. Monitor vital signs every 5 minutes during the initial anginal attack. Tachycardia is common in acute coronary syndrome and acute MI. Rate irregularity can signal atrial fibrillation or frequent supraventricular or ventricular ectopic beats. Blood pressure may rise first from sympathetic stimulation, then fall if cardiac output is compromised. Hypotension often reflects hemodynamic compromise and predicts poor outcomes.

4. Auscultate heart sounds. Monitor rate and rhythm. Unstable angina carries an increased risk of acute life-threatening dysrhythmias in response to ischemia or stress. An S4 gallop is a common early finding. An S3 indicates reduced left ventricular function. Murmurs of mitral regurgitation or ventricular septal defect after the initial presentation indicate a grave prognosis.

5. Elevate the head of the bed if the client is short of breath or during nitrate administration. This eases gas exchange and reduces hypoxia and shortness of breath. Keep the head of the bed no higher than 30 degrees during angina to minimize headache or hypotension and support blood return to the heart and head.

6. Encourage immediate reporting of pain so medications can be given promptly. Timely treatment cuts oxygen consumption and myocardial workload and limits complications. Angina abates with rest or nitrates. A stable, predictable pattern is one thing, but unstable angina escalates in frequency and severity and is not relieved by rest.

7. Monitor for effects and adverse responses to medications, noting BP, heart rate, and rhythm. The goal is to cut myocardial oxygen demand by reducing ventricular stress. Drugs with negative inotropic properties can drop perfusion to already ischemic myocardium. Nitrates and beta-blockers together can have a cumulative effect on cardiac output. Nitrates are usually withheld if systolic BP is 90 mm Hg or less.

2. Administering Medications and Pharmacologic Interventions

Nurses administer the drugs, watch the responses, and teach the patient. The categories below cover antianginal therapy.

1. Nitrates (nitroglycerin, isosorbide) (sublingual, buccal, oral, metered-dose spray). Nitroglycerin is the standard for treating and preventing anginal pain and remains the cornerstone of antianginal therapy. IV and sublingual nitroglycerin vasodilate the coronary arteries and reduce pain. Watch for hypotension and headache after administration. Isosorbide dinitrate gives a rapid vasodilator effect lasting 10 to 30 minutes and can be used prophylactically to prevent or abort attacks.

2. Sustained-release tablets, caplets, chewable tablets, patches, transmucosal ointment. Long-acting forms prevent recurrence by reducing coronary vasospasm and cardiac workload. They can cause headache, dizziness, and lightheadedness that usually pass quickly. If the headache is intolerable, adjust the dose or discontinue.

3. Beta-blockers (acebutolol, atenolol, nadolol, metoprolol, propranolol). Beta-blockers reduce angina by reducing the heart's workload, and alone they often relieve less severe angina. Their negative chronotropic and inotropic effects lower oxygen demand.

4. Calcium channel blockers (bepridil, amlodipine, nifedipine, felodipine, isradipine, diltiazem). These relax coronary vascular smooth muscle, dilate coronary arteries, and reduce peripheral vascular resistance. Amlodipine relaxes coronary smooth muscle and produces vasodilation, improving myocardial oxygen delivery.

5. Analgesics (morphine sulfate). Morphine (2 to 4 mg IV) is the opiate of choice for preinfarction angina. It relieves pain and reduces fear and anxiety. After giving it, assess for pain relief and watch for hypotension and respiratory depression.

6. Lipid-lowering agents: bile acid sequestrants, cholestyramine, colestipol. First-line for lowering serum cholesterol. Note that these can inhibit absorption of fat-soluble vitamins and some drugs, including warfarin, digoxin, and propranolol. Patients started on anti-lipid therapy in the hospital tend to stay on it and get a meaningful drop in recurrent cardiac events.

7. Nicotinic acid and HMG-CoA reductase inhibitors: lovastatin, simvastatin. HMG-CoA reductase inhibitors can cause photosensitivity. Before starting, the patient goes on a cholesterol-lowering diet for 3 to 6 months, then indefinitely.

8. Calcium channel blockers (diltiazem, nifedipine, verapamil, bepridil, amlodipine, felodipine, isradipine). These prevent and terminate ischemia from coronary artery spasm and reduce vascular resistance, lowering BP and cardiac workload.

9. Beta-blockers (atenolol, nadolol, propranolol, esmolol). These reduce heart rate, slow conduction, lower blood pressure, and reduce contractility, balancing myocardial oxygen need against supply.

10. Acetylsalicylic acid and other antiplatelet agents (ticlopidine; glycoprotein IIb/IIIa agents abciximab, eptifibatide). Useful in unstable angina, ASA reduces platelet aggregation and clot formation. For patients with major GI intolerance, alternatives may be needed. IV antiplatelet agents are used alongside angioplasty.

11. IV heparin. A bolus followed by continuous infusion reduces the risk of subsequent MI by limiting the thrombotic complications of plaque rupture in intermediate or high-risk unstable angina. Low-molecular-weight heparin is increasingly used for its more predictable effect, fewer adverse effects (less bleeding risk), longer half-life, and no need for anticoagulation monitoring. Subcutaneous LMWH may be chosen over IV unfractionated heparin.

3. Decreasing Oxygen Demand and Managing Decreased Cardiac Output

Oxygen supply depends on blood flow and oxygen saturation. In atherosclerosis, coronary arteries cannot raise flow under stress, and the resulting shortfall is angina. The following actions reduce oxygen demand.

1. Provide supplemental oxygen as indicated. This raises oxygen available for myocardial uptake and reverses ischemia. Give it to all patients with acute ischemic pain. Hypoxia is common from reduced perfusion and adds stress to the compromised myocardium.

2. Watch for associated symptoms: dyspnea, nausea, vomiting, dizziness, palpitations, urge to void. Decreased cardiac output during ischemia stimulates the autonomic nervous system and produces vague sensations the patient may not connect to the attack. Weakness or numbness in the arms, wrists, and hands, plus shortness of breath, pallor, diaphoresis, dizziness, lightheadedness, nausea, and vomiting, may accompany the pain.

3. Provide light meals low in saturated fat, cholesterol, sodium, and refined sugar. Have the client rest for an hour after meals. This cuts the myocardial workload of digestion and the risk of an attack. Lower saturated fat and cholesterol reduce cardiovascular risk. Refined sugars are empty calories that convert to fat. Excess sodium drives water retention, vascular volume, and cardiac workload.

4. Monitor vital signs and cardiac rhythm. Tachycardia can come from pain, anxiety, hypoxemia, and reduced output, and a faster rate plus stronger contraction raises oxygen demand. BP may swing high or low. ECG changes showing dysrhythmias signal the need for further evaluation and treatment.

5. Auscultate breath and heart sounds. Listen for murmurs. S3, S4, or crackles can appear with cardiac decompensation or some drugs (especially beta-blockers). New murmurs may reveal a valvular cause for chest pain (aortic stenosis, mitral stenosis) or papillary muscle rupture. A large area of myocardium at risk signals higher-risk disease.

6. Note skin color and the presence and quality of pulses. Peripheral circulation drops when cardiac output falls, leaving the skin pale or gray and the pulses weaker.

7. Monitor pulse oximetry or ABGs as indicated. Use pulse oximetry to keep oxygen saturation above 95%, unless the patient has COPD and is a carbon dioxide retainer.

8. Monitor labs, especially PTT and aPTT. Heparin dosing follows the aPTT. Heparin therapy is usually therapeutic when the aPTT is 1.5 to 2 times normal.

9. Measure cardiac output and other functional parameters as indicated. Cardiac index, preload, afterload, contractility, and cardiac work can be measured noninvasively, including by thoracic electrical bioimpedance. These guide response to treatment and the need for emergency care. Account for the patient's circadian hemodynamic variability when reading changes.

10. Place the client at complete rest during anginal episodes. This cuts myocardial oxygen demand and the risk of tissue injury. A mismatch of myocardial oxygen supply and demand causes ischemia or infarction, and infarction is irreversible.

11. Maintain bed or chair rest in a position of comfort during acute episodes. This lowers oxygen demand, myocardial workload, and the risk of decompensation. Unstable angina warrants admission for bed rest with continuous telemetry.

12. Provide adequate rest periods and pace self-care. This conserves energy and reduces cardiac workload. The activity level that triggers symptoms varies, but most patients with stable angina avoid symptoms in daily activity simply by slowing down.

13. Stress avoiding straining, especially during defecation. Teach the patient to avoid the Valsalva maneuver (forced expiration against a closed glottis), which means bearing down during defecation or breath-holding while repositioning. Valsalva causes vagal stimulation and bradycardia, often followed by rebound tachycardia, both of which can impair cardiac output.

14. Administer supplemental oxygen as needed. This raises oxygen available for myocardial uptake, improving contractility and reducing ischemia and lactic acid. Oxygen is indicated for hypoxia (oxygen saturation below 93%) and for evidence of shock.

15. Discuss and prepare for stress testing and cardiac catheterization when indicated. Stress testing assesses ventricular health and strength and can be paired with echocardiography or myocardial perfusion scintigraphy. Stress echocardiography has an overall sensitivity of 78% and a specificity of 77%. Coronary angiography via cardiac catheterization is the gold standard for CAD, locating lesions and the degree of occlusion.

4. Monitoring and Preventing Myocardial Complications

Catch complications (cardiac arrest, heart failure, dysrhythmias) early by assessing the cause, monitoring vitals, and treating with oxygen, medications, and lifestyle change.

1. Evaluate pain in the jaw, neck, shoulder, arm, or hand, typically on the left. Cardiac pain radiates and is often referred to more superficial sites served by the same spinal cord level. It may come with severe apprehension and a sense of impending death, felt deep behind the sternum. It is poorly localized and may spread to the neck, jaw, shoulders, and inner upper arms, usually the left.

2. Monitor serial ECG changes. Ischemia during an attack can cause transient ST depression or elevation and T-wave inversion. Serial tracings confirm ischemic changes, which may disappear once the patient is pain-free, and provide a baseline for later comparison.

3. Instruct the client to notify the nurse immediately when chest pain, pressure, or heaviness occurs. Pain and decreased output drive sympathetic release of norepinephrine, raising platelet aggregation and thromboxane A2, a potent vasoconstrictor that can trigger coronary spasm and prolong the attack. Unbearable pain can cause a vasovagal response, dropping BP and heart rate. Some patients describe angina as pressure or heaviness, so evaluate those complaints quickly as indicators of ischemia.

4. Assess and monitor for signs and symptoms of heart failure. Angina is a symptom of underlying pathology that can compromise cardiac function to the point of decompensation. Weakness or numbness in the arms, wrists, and hands, shortness of breath, pallor, diaphoresis, dizziness, and nausea may appear alone but still represent ischemia.

5. Administer antianginal medications promptly and as indicated. See pharmacologic management above.

6. Closely monitor the cardiac monitor for silent ischemia. Silent ischemia is objective ECG evidence of ischemia without anginal symptoms. One-third of patients having a heart attack do not report chest pain.

7. Prepare for surgical intervention: angioplasty with or without intracoronary stent, valve replacement, CABG, as indicated. Angioplasty (PTCA) raises coronary flow by compressing lesions and dilating the vessel lumen. Intracoronary stents add structural support and improve long-term patency, and this approach is preferred over the more invasive CABG. CABG is recommended when testing confirms ischemia from left main disease or symptomatic three-vessel disease, especially with left ventricular dysfunction. Stents can also help the variant form of angina where vasospasm impairs flow.

8. Prepare for transfer to critical care if the condition warrants. Prolonged chest pain with decreased output reflects complications needing emergency intervention and specialist monitoring.

5. Providing Emotional Support and Reducing Anxiety

Chest pain in cardiovascular disease can signal new or unresolved coronary issues. Social isolation, adverse life events, chronic conditions, poor coping, distress, anxiety, and depression can be cause or consequence, and this comorbidity weighs on quality of life even when anxiety is in remission. Support the patient as follows.

1. Keep a calm environment and stay with the client during pain or anxiety. Anxiety releases catecholamines that raise myocardial workload and can prolong ischemic pain. Your presence reduces fear and helplessness while you stay ready for an acute emergency.

2. Evaluate the client's and family's understanding of the diagnosis. They are absorbing new information and lifestyle changes. Knowing their perceptions lets you individualize care and choose the right interventions.

3. Observe physical responses: restlessness, vital sign changes, repetitive movements. This gauges the degree of concern, especially against verbal comments, and notes the match between verbal and nonverbal cues. A pain-free variant of angina exists and may limit reporting, with the patient dismissing discomfort as anxiety-driven palpitations.

4. Identify previous coping strengths and current areas of control. This focuses attention on the patient's own capabilities and sense of control, fostering successful coping and reassurance.

5. Explain the purpose of tests and procedures such as stress testing. This reduces anxiety from fear of the unknown. Graded stress testing is the most widely used evaluation for chest pain and gives prognostic information in stable angina.

6. Promote expression of feelings and fears, and normalize them. Unexpressed feelings create internal turmoil and affect self-image. Verbalizing concerns reduces tension and supports coping. Negative self-talk raises anxiety and can worsen attacks.

7. Provide opportunities for questions and answer honestly. This builds trust and prevents misinterpretation. Make sure the patient understands as well as the healthcare team does.

8. Encourage family and friends to treat the client as before. This reassures the patient that their role has not changed. Patients with angina often fear losing their roles, or that the pain leads to MI or death.

9. Tell the client the regimen is designed to limit future attacks and increase cardiac stability. This builds confidence in the plan. Patients are often told that needing more than three nitroglycerin tablets means they need a higher level of care, and some are told to take aspirin as well.

10. Encourage stress reduction or relaxation techniques. Explore options with the patient. Music therapy, for example, has shown hemodynamic effects that may reduce cardiac workload.

11. Involve the client and family in decision-making. This promotes control and cooperation and reduces helplessness, restoring a sense of independence.

12. Refer to a spiritual counselor for spiritual needs. Addressing spiritual needs can ease anxiety. Let the patient practice their religion as long as it does not interfere with their care or the hospital environment.

6. Patient Education for Lifestyle Change

Teaching aims to build understanding of the illness, recognition of ischemia symptoms, the right actions during symptoms, and prevention of chest pain and CAD progression. Good education reduces the frequency and severity of attacks, slows the disease, and prevents complications.

1. Assess readiness and ability to learn, plus culture and information needs. This ensures information is delivered at the right time and in the right way for the patient and caregivers.

2. Identify and discuss nonmodifiable risk factors. Many women have varied symptoms before and during an acute MI. Recognizing that many women do not get crushing chest pain matters so their symptoms are not trivialized.

3. Review cholesterol, differentiate LDL and HDL, and stress periodic measurement. Recommended LDL is about 160 mg/dL, but patients with two or more risk factors (smoking, hypertension, diabetes mellitus, positive family history) should stay around 130 mg/dL, and those with CAD should keep LDL below 100 mg/dL. HDL below 35 to 45 is a risk factor, and a level above 60 mg/dL is an advantage. Oxidative stress is the most significant contributor to atherosclerosis through LDL oxidation and reduced nitric oxide.

4. Discuss the pathophysiology and the need to prevent and manage attacks. Patients need to know why angina happens and how to control it. Primary prevention is the most effective and cost-efficient way to reduce disease burden in the population.

5. Help the client and support person identify sources of physical and emotional stress and ways to avoid them. This is central to prevention. Mental stress activity in the brain's frontal lobe correlates directly with angina. In one study of 148 people with CAD (average age 62), activity in the inferior frontal lobe during mental stress (arithmetic and public speaking) tracked with the severity of self-reported angina.

6. Encourage avoiding triggers (stress, intense exertion, large heavy meals near bedtime, temperature extremes). This reduces ischemic episodes. Psychological factors may be stronger determinants of angina than CAD burden. A heavy meal pulls blood to the mesentery for digestion and away from the heart.

7. Teach female clients to recognize angina equivalents. Women should know about unexplained shortness of breath, cold sweat, sudden fatigue, nausea, and lightheadedness. More women than men die each year of acute coronary syndrome in the US, a fact largely unknown to providers.

8. Review weight control, smoking cessation, dietary change, and exercise. Knowing the risk factors lets the patient act on them. Patients with high cholesterol who do not respond to a 6-month low-fat diet and regular exercise will need medication. Population-wide education on diet and exercise reduces multiple coronary risk factors.

9. Encourage the prescribed reconditioning program and caution against exhaustion. Fear of triggering attacks can make patients avoid prescribed activity meant to build myocardial strength and collateral circulation. Most benefit comes with at least 150 minutes a week of moderate activity such as brisk walking, with more activity giving more benefit.

10. Discuss illness impact on work, driving, sexual activity, and hobbies, and provide information and privacy. Patients may avoid usual activities for fear of an attack or death. Take nitroglycerin prophylactically before any activity known to trigger angina. Prognosis depends on disease burden, the vascular beds involved, and the degree of flow limitation, and many patients survive years despite heavy disease.

11. Demonstrate self-monitoring of pulse and BP during and after activity, and how to schedule activity. This lets the patient modify activities to stay below the anginal threshold. Pain may start with exertion (stairs, intercourse, raking leaves) and ease within minutes of rest.

12. Discuss what to do when an attack occurs: stop activity, keep rescue NTG on hand, take PRN medication, use relaxation techniques. Being prepared removes the fear of not knowing what to do. Carry nitroglycerin at all times, but because it is unstable, keep it in its original capped dark glass bottle. Never move tablets into metal or plastic pillboxes.

13. Caution against certain herbs and medications. Ginseng can cause hypertension. St. John's wort should be avoided with cardiac drugs, since combining it with antiarrhythmics, beta-blockers, and calcium channel blockers can reduce their bioavailability and let dysrhythmias or hypertension return.

14. Promote smoking cessation programs. Smoking cessation is the single most effective intervention to reduce coronary atherosclerosis, associated with a 7 to 47% reduction in CAD in primary prevention.

15. Review prescribed medications for preventing attacks. Angina often requires several drugs to lower myocardial workload, improve circulation, and control attacks, with goals of reducing morbidity and mortality and preventing complications.

16. Discuss aspirin and other antiplatelet agents as indicated. ASA may be given daily to reduce platelet aggregation and improve coronary circulation. Chewing a non-enteric-coated aspirin at the start of chest pain reduces mortality, and the non-enteric form is preferred because chewing increases absorption in the mouth.

17. Review symptoms to report: increased frequency of attacks and changes in medication response. This can prolong survival in unstable angina and avoid both undue concern and dangerous delays. Document pain characteristics, heart rate and rhythm, BP, respirations, temperature, skin color, peripheral pulses, urine output, mentation, and tissue perfusion. Evaluate chest discomfort, pressure, or heaviness quickly as indicators of ischemia.

18. Stress the importance of followup appointments. Angina reflects progressive CAD that needs monitoring and occasional regimen adjustment. Refer to cardiac rehab for smoking cessation, weight management, exercise, and lipid control.
