A 52-year-old man with exertional chest pain that improves with rest has a presentation that is highly concerning for stable angina associated with coronary artery disease (CAD). His cardiovascular risk is increased by hypertension, obesity, hyperlipidemia, age, male sex, and significant chronic caregiver stress. A detailed cardiovascular history and physical examination, appropriate diagnostic testing, and aggressive management of modifiable risk factors are important to determine the cause of his symptoms and reduce the risk of myocardial infarction, stroke, and other cardiovascular complications.
The pattern of chest discomfort is particularly important. Pain that develops during physical activity and resolves after several minutes of rest is characteristic of myocardial ischemia caused by an imbalance between myocardial oxygen demand and coronary blood supply. However, the patient requires further evaluation because chest pain can have both cardiac and noncardiac causes.
A 52-year-old male house painter presents to a clinic with chronic fatigue and mild chest discomfort that occurs while working. His symptoms generally resolve within approximately five minutes after he rests and sometimes radiate to his left arm.
Three years earlier, the patient was advised to make lifestyle changes because of mild hyperlipidemia. Since that time, however, he has gained approximately 30 pounds. His medical history includes anxiety, hyperlipidemia, a previous cholecystectomy, and vasectomy. He reports no tobacco or nicotine use.
The patient also has substantial psychosocial stress. He is the primary caregiver for his wife, who has multiple sclerosis, while also providing financial support for his daughter and grandson. These responsibilities contribute to his reluctance to seek regular medical care.
Initial assessment findings include:
Blood pressure: 158/78 mmHg
Heart rate: 87 beats/minute
Respiratory rate: 20 breaths/minute
BMI: 32 kg/m², consistent with obesity
The healthcare provider orders an electrocardiogram (ECG), lipid profile, cardiac biomarker testing, and C-reactive protein (CRP) testing.
The patient’s reluctance to continue medical care is clinically important because untreated cardiovascular risk factors and delayed evaluation of exertional chest pain may increase the likelihood of serious cardiovascular events.
The patient’s symptom pattern is consistent with stable angina, although a definitive diagnosis requires appropriate clinical evaluation. Stable angina occurs when the heart requires more oxygen during exertion than narrowed coronary arteries can supply.
The classic pattern includes chest discomfort that:
Occurs predictably with physical exertion or emotional stress
Improves with rest
May feel like pressure, tightness, squeezing, heaviness, or discomfort
May radiate to the arm, shoulder, neck, jaw, or back
Because symptoms can change over time, the nurse should determine whether the patient’s episodes are becoming more frequent, lasting longer, occurring with less activity, or appearing at rest. Such changes may indicate an acute coronary syndrome rather than predictable stable angina.
A structured symptom assessment can help characterize the patient’s chest discomfort and determine the urgency of further evaluation.
Ask the patient to identify exactly where the discomfort begins and whether it spreads elsewhere. The quality of the sensation should also be clarified. Terms such as pressure, heaviness, squeezing, tightness, burning, or discomfort may provide more useful clinical information than simply asking whether the patient has “pain.”
The nurse should determine when the symptoms began, how often they occur, how long each episode lasts, and whether the episodes are becoming more frequent or severe.
Important questions include:
What activity triggers the chest discomfort?
Does it occur while climbing stairs, walking, or performing physical work?
Does it occur during emotional stress?
How long does each episode last?
Does the discomfort stop after resting?
Does it occur at rest or awaken the patient from sleep?
Has the pattern changed recently?
The assessment should also identify symptoms that may accompany myocardial ischemia, including:
Shortness of breath
Diaphoresis
Nausea or vomiting
Dizziness
Near-syncope or syncope
Palpitations
Unusual weakness or fatigue
Pain or discomfort involving the jaw, neck, shoulder, arm, or back
A change from predictable exertional symptoms to symptoms occurring at rest or with progressively less exertion requires urgent clinical attention.
A focused physical examination should complement the patient’s symptom history. The goal is to identify evidence of cardiovascular disease, impaired perfusion, hypertension, heart failure, or other conditions that could contribute to his symptoms.
The assessment should include evaluation of:
Blood pressure and heart rate
Peripheral pulses
Capillary refill
Skin color and temperature
Carotid arteries, including assessment for bruits when appropriate
Jugular venous pressure or jugular venous distention
Cardiac rate and rhythm
Heart sounds and murmurs
Peripheral edema
Lung sounds
Signs of poor peripheral circulation
Symptoms of intermittent claudication
Lung auscultation is particularly relevant because crackles, for example, may suggest pulmonary congestion associated with heart failure.
Orthostatic blood pressure measurements may also be appropriate depending on the patient’s symptoms, medication history, and clinical presentation.
An ECG is an important component of cardiovascular assessment, although a normal resting ECG does not necessarily exclude coronary artery disease. Additional testing should be guided by the patient’s symptoms, cardiovascular risk, examination findings, and estimated likelihood of obstructive coronary disease.
Depending on the clinical assessment, further evaluation may include laboratory testing, noninvasive cardiac imaging, coronary computed tomography angiography, stress testing, or referral to cardiology.
Cardiac biomarkers such as troponin are particularly important when acute myocardial injury or acute coronary syndrome is suspected. Their interpretation should be based on the clinical presentation and serial testing when indicated.
C-reactive protein is a marker of systemic inflammation. When high-sensitivity CRP (hs-CRP) is used in an appropriate clinical context, it may contribute to cardiovascular risk assessment.
An elevated CRP level, however, does not diagnose coronary artery disease. CRP can increase because of many conditions, including infection, obesity, autoimmune disease, trauma, and other inflammatory processes.
Therefore, an elevated CRP should not be interpreted as evidence that the patient’s chest pain is caused by CAD. The result must be considered alongside his symptoms, cardiovascular risk factors, physical examination, ECG, lipid profile, and other diagnostic findings.
Although stable angina associated with CAD is an important consideration, the differential diagnosis should remain broad until the evaluation is complete.
Potential cardiovascular causes include:
Coronary artery disease with stable angina
Acute coronary syndrome
Coronary artery vasospasm
Coronary thrombosis
Severe uncontrolled hypertension
Aortic stenosis
Aortic regurgitation
Hypertrophic cardiomyopathy
Other structural or congenital heart conditions
The clinical history and diagnostic findings help determine which conditions are most likely.
Chest discomfort may also result from noncardiac conditions, including:
Gastroesophageal reflux disease (GERD)
Esophageal spasm
Musculoskeletal chest pain
Costochondritis
Anxiety or panic disorder
Biliary disease
A noncardiac explanation should not be assumed simply because the patient has anxiety or another potential alternative diagnosis. Cardiac causes must be appropriately evaluated first when the symptom pattern raises concern for myocardial ischemia.
This patient has several modifiable and nonmodifiable cardiovascular risk factors.
The patient’s modifiable risk factors include:
Hypertension
Hyperlipidemia
Obesity
Potentially inadequate physical activity
Chronic psychosocial stress
Dietary and weight-related factors
His blood pressure of 158/78 mmHg is elevated and warrants appropriate follow-up and management. His BMI of 32 kg/m² also indicates obesity, which is associated with increased cardiovascular risk.
The patient is also at increased risk because of:
Age
Male sex
Existing cardiovascular risk profile
Risk assessment should consider the patient’s complete clinical picture rather than any single factor.
Patient education should focus on realistic and sustainable changes rather than presenting an overwhelming list of lifestyle requirements. Because the patient has significant work and caregiving responsibilities, the care plan should be individualized around his daily circumstances.
A heart-healthy eating pattern can help improve blood pressure, lipid levels, body weight, and overall cardiovascular health.
The patient should be encouraged to emphasize:
Vegetables and fruits
Whole grains
Legumes
Nuts and seeds
Fish and other healthy protein sources
Lean or minimally processed protein sources
Unsaturated fats in place of saturated fats
He should also reduce intake of highly processed foods, excess sodium, added sugars, and foods high in saturated fat.
Rather than focusing only on a specific dietary cholesterol limit, current cardiovascular prevention recommendations emphasize the overall dietary pattern and replacement of saturated fats with unsaturated fats.
Once the patient’s chest pain has been appropriately evaluated and exercise is considered safe, physical activity should be gradually incorporated into his routine.
Weight management is also important because obesity contributes to hypertension, dyslipidemia, insulin resistance, and cardiovascular risk.
The goal should be sustainable weight reduction rather than rapid weight loss. Even modest improvements in body weight, diet, and activity can contribute to better cardiovascular health.
The patient should understand that lifestyle modification and medication therapy may both be necessary to control cardiovascular risk factors.
Education should address:
Taking antihypertensive medications exactly as prescribed
Monitoring blood pressure when recommended
Following prescribed lipid-lowering therapy
Attending follow-up appointments
Discussing medication side effects rather than discontinuing therapy independently
Reviewing over-the-counter medications with a healthcare professional
Some medications and substances can increase blood pressure or interfere with cardiovascular management. These may include certain NSAIDs and sympathomimetic decongestants.
Medication education should be individualized according to the medications actually prescribed to the patient.
The patient’s statement that he “doesn’t have time to be sick” is an important barrier to care. His responsibilities as a caregiver and financial provider may cause him to prioritize his family’s needs over his own health.
Simply telling him to attend more appointments may not be sufficient. The healthcare team should acknowledge the practical challenges he faces and develop a realistic plan.
Healthcare professionals can:
Ask about the patient’s caregiving responsibilities and emotional stress.
Explain how untreated cardiovascular disease could affect his ability to support his family.
Help him understand the purpose of each diagnostic test.
Coordinate appointments when possible to reduce time away from work.
Encourage consistent monitoring of blood pressure and cholesterol.
Provide clear instructions about symptoms requiring urgent evaluation.
Refer him for appropriate cardiology evaluation.
Consider social work or community-based caregiver resources.
Encourage counseling or other stress-management support when appropriate.
Addressing psychosocial barriers is an important part of patient-centered cardiovascular care.
Patients with suspected stable angina should be taught that a change in their usual symptom pattern can indicate a medical emergency.
Urgent evaluation is particularly important when chest discomfort:
Occurs at rest
Becomes more severe or frequent
Lasts longer than usual
Occurs with progressively less activity
Is associated with significant shortness of breath
Is accompanied by fainting, severe weakness, diaphoresis, or other concerning symptoms
New, severe, or persistent chest pain should not be assumed to be anxiety, indigestion, or ordinary fatigue.
The immediate clinical priorities are to evaluate the cause of his exertional chest pain, determine his cardiovascular risk, and address modifiable factors that could contribute to future cardiovascular events.
Key priorities include:
Characterizing the patient’s chest pain pattern
Evaluating for coronary artery disease
Determining whether symptoms could represent acute coronary syndrome
Assessing and managing hypertension
Reassessing lipid levels and cardiovascular risk
Addressing obesity and lifestyle factors
Reviewing appropriate diagnostic testing
Educating the patient about warning signs
Addressing caregiver stress and barriers to care
Coordinating appropriate follow-up and specialist evaluation
Early identification and management of cardiovascular risk can help reduce the likelihood of myocardial infarction, stroke, heart failure, and premature cardiovascular death.
This 52-year-old man’s exertional chest discomfort that improves with rest is concerning for stable angina and possible underlying coronary artery disease. His hypertension, hyperlipidemia, obesity, age, male sex, and chronic caregiver stress further increase his cardiovascular risk.
A complete evaluation should combine a detailed chest pain history, focused cardiovascular examination, ECG and appropriate laboratory testing, and additional diagnostic studies based on his clinical risk. CRP may contribute to cardiovascular risk assessment in selected circumstances, but an elevated result is nonspecific and cannot independently diagnose CAD.
Long-term management should address blood pressure, cholesterol, weight, diet, physical activity, medication adherence, and psychosocial stress. Because caregiving responsibilities are a major barrier for this patient, an effective plan should be practical, patient-centered, and supported by appropriate community or multidisciplinary resources.
The presentation is most concerning for stable angina associated with coronary artery disease because the patient’s chest discomfort occurs during exertion, improves with rest, and sometimes radiates to his left arm. Further evaluation is necessary to establish the diagnosis and exclude acute coronary syndrome and other causes of chest pain.
CRP is an inflammatory biomarker that may provide additional information about cardiovascular risk in selected patients. However, an elevated CRP is nonspecific and does not establish the presence of coronary artery disease.
The major risk factors identified in the case include hypertension, hyperlipidemia, obesity, age, male sex, and chronic psychosocial stress. His weight gain and potential lifestyle challenges may further contribute to his overall cardiovascular risk.
Chronic caregiving stress can affect sleep, physical activity, diet, emotional well-being, blood pressure management, and adherence to healthcare recommendations. Addressing caregiver burden can therefore be an important part of comprehensive cardiovascular care.
A heart-healthy dietary pattern, appropriate physical activity, weight management, blood pressure control, lipid management, avoidance of tobacco, appropriate alcohol intake, stress management, and adherence to prescribed treatment can all contribute to cardiovascular risk reduction.
The timing, location, quality, duration, triggers, relieving factors, radiation, and associated symptoms help clinicians determine whether chest discomfort is consistent with myocardial ischemia and whether the symptom pattern may represent stable angina, acute coronary syndrome, or another condition.
Chest pain that is new, severe, prolonged, occurs at rest, becomes progressively more frequent, or is accompanied by symptoms such as severe shortness of breath, fainting, diaphoresis, or significant weakness requires urgent medical evaluation.
This NU556 cardiac and associated risk disorders case study demonstrates how cardiovascular assessment extends beyond identifying a single diagnosis. The patient’s exertional chest pain is concerning for stable angina, while his hypertension, hyperlipidemia, obesity, and psychosocial stress increase his overall cardiovascular risk.
Effective nursing and medical management requires careful symptom assessment, appropriate diagnostic evaluation, cardiovascular risk reduction, patient education, medication adherence, and attention to psychosocial barriers. A patient-centered approach that considers the individual’s work and caregiving responsibilities can improve engagement with care and support better long-term outcomes.
