chest pain - Nursing Case Study
Pathophysiology
• Primary mechanism: Ischemia - Reduced blood flow to the heart muscle often due to blockages in coronary arteries. This lack of oxygen leads to chest pain known as angina, as heart tissues struggle to function properly.
• Secondary mechanism: Inflammation - Conditions like pericarditis involve inflammation of the pericardium, the sac surrounding the heart, leading to sharp chest pain that worsens with breathing or lying down.
• Key complication: If ischemia is prolonged, it can lead to myocardial infarction (heart attack), where heart tissue is damaged or dies due to lack of oxygen, significantly increasing risk for serious heart complications.

Section 1
The initial assessment reveals that the patient's mild chest pain is associated with activities such as climbing stairs or carrying heavy objects, but it subsides with rest. The pain is located centrally in the chest and is described as a pressure rather than sharp. On physical examination, the patient appears comfortable at rest, with no visible distress. Heart sounds are regular with no murmurs, rubs, or gallops. Lungs are clear to auscultation bilaterally, and there is no peripheral edema noted. The patient's skin is warm and well-perfused, and capillary refill is less than 2 seconds.
Given the presentation, a 12-lead electrocardiogram (ECG) is performed to further assess cardiac function. The ECG shows normal sinus rhythm with no acute ischemic changes, such as ST elevation or T wave inversion, which are often suggestive of myocardial injury. However, there are non-specific ST segment changes that warrant further investigation. Basic laboratory tests, including a complete blood count (CBC) and metabolic panel, are within normal limits. Cardiac enzyme levels, such as troponin, are ordered to rule out any potential myocardial damage. The initial troponin level is within normal range, indicating no acute myocardial infarction.
These findings suggest that the chest pain is likely stable angina, possibly related to physical exertion. The immediate nursing priority is to educate the patient about lifestyle modifications, such as avoiding heavy lifting and managing stress, while monitoring for any changes in symptoms. An appointment for a stress test is scheduled to assess the severity of any underlying coronary artery disease. The patient is advised to continue with over-the-counter antacids and is counseled on recognizing signs of worsening chest pain that would require immediate medical attention. As the patient leaves the clinic, he is reminded to follow up with his primary care physician for ongoing management and evaluation of his heart health.

A week after the initial visit, the patient returns to the clinic for a follow-up appointment. During this visit, the patient reports some improvement in managing his chest pain by avoiding strenuous activities and adhering to the recommended lifestyle changes. However, he mentions experiencing occasional episodes of mild chest discomfort even with minimal exertion, such as walking short distances. These episodes are brief and still resolve with rest. The patient also reports taking antacids as advised, which have provided some relief from associated gastrointestinal symptoms.
In light of these new symptoms, a repeat 12-lead electrocardiogram (ECG) is performed. This ECG shows a similar pattern to the previous one, with normal sinus rhythm and non-specific ST segment changes, but no acute ischemic changes. A follow-up troponin test is again within normal limits, confirming the absence of acute myocardial injury. Vital signs are stable, with a blood pressure of 128/78 mmHg, heart rate of 72 beats per minute, respiratory rate of 18 breaths per minute, and oxygen saturation of 98% on room air. The patient remains well-perfused, with warm skin and normal capillary refill.
Given these findings, the healthcare team decides to expedite the stress test appointment to gather more detailed information about the patient's cardiac function during physical activity. Additionally, the patient is encouraged to keep a diary of his symptoms, noting the frequency and severity of any chest pain episodes. This information will be crucial for the primary care physician in determining whether further intervention, such as medication adjustment or referral to a cardiologist, is necessary. The patient is reminded of the importance of promptly seeking medical attention if his symptoms worsen, particularly if the chest pain becomes more severe, frequent, or occurs at rest.
Section 3
In the days following the expedited stress test, the patient returns to the clinic to discuss the results and any necessary changes to his management plan. The stress test indicates that while the patient does experience some chest discomfort during exertion, there is no evidence of significant coronary artery disease or ischemia. The findings suggest that the patient's symptoms may be more related to non-cardiac causes, possibly due to muscle strain or gastrointestinal issues, rather than a primary cardiac problem.
During this follow-up visit, the patient's vital signs remain stable, with a blood pressure of 126/80 mmHg, heart rate of 70 beats per minute, respiratory rate of 16 breaths per minute, and oxygen saturation of 99% on room air. The patient reports continuing to manage his symptoms with lifestyle modifications and finds some relief with the use of antacids. He has diligently kept a diary of his symptoms, noting a pattern that associates his discomfort with specific activities and dietary choices. This information supports the hypothesis of a non-cardiac origin, prompting the healthcare team to consider further evaluation for gastrointestinal or musculoskeletal causes.
With these new insights, the healthcare team decides to adjust the patient's management plan. They recommend a trial of a proton pump inhibitor (PPI) to better control any underlying acid reflux that might be contributing to his symptoms. Additionally, they provide guidance on gentle stretching exercises to alleviate any muscle strain and reinforce the importance of maintaining a balanced diet to minimize gastrointestinal triggers. The patient is scheduled for a follow-up appointment in two weeks to reassess his response to these interventions and determine if further diagnostic testing or referrals are required. This approach aims to address the patient's symptoms comprehensively while ensuring his continued safety and well-being.

Response to Interventions
Two weeks after the implementation of the new management plan, the patient returns to the clinic for his follow-up appointment. He reports a noticeable decrease in the frequency and intensity of his chest discomfort, attributing this improvement primarily to the use of the proton pump inhibitor (PPI). He notes that his symptoms are now less frequent, especially after meals, and he no longer experiences the same level of discomfort during physical activity. The patient also mentions that incorporating gentle stretching exercises into his daily routine has helped alleviate muscle tension, further reducing his symptoms.
During the follow-up assessment, the nurse documents stable vital signs: blood pressure at 124/78 mmHg, heart rate at 68 beats per minute, respiratory rate at 14 breaths per minute, and oxygen saturation at 98% on room air. The patient continues to maintain a symptom diary, which now shows a significant decline in episodes of discomfort and no new patterns of distress. Encouraged by these results, the healthcare team decides to continue the current management approach, emphasizing the importance of adhering to lifestyle modifications and medication regimen.
The team discusses with the patient the potential benefits of ongoing monitoring and education to prevent any recurrence of symptoms. They advise scheduling another follow-up in one month to ensure sustained improvement and to determine if any further adjustments are necessary. This carefully planned approach aims to support the patient's journey towards a healthier lifestyle, ensuring that any underlying issues remain well-managed while promoting overall well-being.
Section 5
As the patient continues with his management plan, he experiences a minor complication: mild gastritis, likely a side effect of the proton pump inhibitor (PPI) therapy. During his next follow-up visit, the patient mentions feeling occasional stomach discomfort, particularly in the mornings before breakfast. The nurse conducts a focused assessment and notes that while the patient's abdominal examination reveals mild epigastric tenderness, there are no alarming signs such as severe pain or gastrointestinal bleeding.
Laboratory results are reviewed, showing a mild reduction in hemoglobin levels from 14.5 g/dL to 13.2 g/dL, hinting at potential chronic gastritis effects. However, his complete blood count remains within acceptable ranges, and there is no evidence of active bleeding. The healthcare team decides to adjust the patient's medication regimen by introducing a histamine-2 blocker to mitigate gastric irritation and advises the patient to take the PPI with meals to further reduce gastric discomfort.
The patient is educated about recognizing signs of worsening gastritis and is encouraged to maintain his symptom diary with added focus on any gastrointestinal symptoms. The team reiterates the importance of dietary adjustments, such as avoiding spicy and acidic foods, to minimize irritation. A follow-up appointment is scheduled in two weeks to reassess his symptoms and ensure that these minor complications are effectively managed while continuing to monitor his overall progress. This approach aims to fine-tune the management plan while preventing any escalation of symptoms, reinforcing the patient's path towards stability and improved quality of life.
