chest pain - Nursing Case Study

Pathophysiology

• Primary mechanism: Myocardial ischemia occurs when blood flow to the heart muscle is reduced, often due to atherosclerosis, leading to oxygen deprivation and chest pain or angina.

• Secondary mechanism: Gastroesophageal reflux disease (GERD) can cause chest pain when stomach acid irritates the esophagus, mimicking cardiac pain.

• Key complication: Untreated myocardial ischemia can progress to myocardial infarction, causing significant heart muscle damage and increasing morbidity and mortality.

Section 1

As the nursing team conducts an initial assessment, the focus is on evaluating the severity and implications of the patient's chest pain. Upon auscultation, the nurse notes an S4 gallop, suggestive of decreased left ventricular compliance, potentially indicating myocardial ischemia. The chest pain is persistent, rated by the patient as an 8 out of 10 on the pain scale, and is not relieved by rest. The patient's skin appears slightly diaphoretic, and he continues to experience shortness of breath. Given his history of hypertension and hyperlipidemia, the possibility of acute coronary syndrome is high on the differential diagnosis.

Considering the potential for myocardial infarction, the healthcare team initiates further diagnostic testing. An electrocardiogram (ECG) is performed, revealing ST-segment depression in the lateral leads, which is indicative of ischemia. Blood tests are ordered, including cardiac biomarkers such as troponin, which shows an elevated level of 0.08 ng/mL, confirming myocardial injury. These findings, combined with his clinical presentation, support the diagnosis of unstable angina, necessitating urgent medical intervention to prevent progression to a myocardial infarction.

The patient is promptly started on a nitroglycerin infusion to alleviate chest pain and improve coronary blood flow. Aspirin and a beta-blocker are administered to reduce myocardial oxygen demand. Despite these interventions, the patient's oxygen saturation remains at 92% on room air, prompting the administration of supplemental oxygen to maintain adequate oxygenation. As the team continues to closely monitor his vital signs and symptoms, they prepare for potential escalation of care, including possible transfer to a higher-acuity setting for further evaluation and management by cardiology specialists. This situation underscores the need for vigilant monitoring and timely intervention to mitigate the risk of further cardiac complications.

Section 2

As the healthcare team monitors the patient closely, a change in his status becomes apparent. Despite the administration of nitroglycerin, aspirin, and a beta-blocker, the patient reports an increase in chest pain, now rated 9 out of 10. His diaphoresis has intensified, and he appears increasingly anxious. The patient's vital signs are reassessed, revealing a heart rate that has risen to 110 beats per minute, blood pressure of 150/95 mmHg, and a respiratory rate of 24 breaths per minute. His oxygen saturation, even with supplemental oxygen, is now fluctuating between 89% and 91%.

In response to these concerning changes, the healthcare team orders an urgent repeat ECG, which now shows evolving ST-segment elevation in the anterior leads, suggesting a progression from unstable angina to an acute myocardial infarction. The clinical picture is further complicated by the patient's lab results, with his troponin levels rising sharply to 0.18 ng/mL, indicating increased myocardial damage. The team acts swiftly to escalate care, contacting the cardiology team for immediate intervention.

The cardiologists recommend the initiation of a heparin drip to further reduce the risk of thrombus formation, and the patient is prepared for potential transfer to the cardiac catheterization lab for angiography and possible revascularization. This escalation highlights the critical need for dynamic clinical reasoning, as the team adapts to the patient's rapidly changing condition to prevent further cardiac complications. Throughout this process, the nursing team remains vigilant, ensuring that the patient is continuously monitored and that any further changes in his condition are promptly addressed.

Section 3

As the patient is transferred to the cardiac catheterization lab, the nursing team continues to monitor his condition closely. Upon arrival, the patient appears pale and is increasingly diaphoretic, indicating a potential deterioration in his hemodynamic status. His heart rate has further escalated to 120 beats per minute, while his blood pressure has dropped to 130/85 mmHg, suggesting a compensatory response to decreased cardiac output. The respiratory rate remains elevated at 26 breaths per minute, and oxygen saturation has dipped to 87% despite being on high-flow oxygen. The patient's anxiety has also increased, and he is now reporting nausea, which necessitates additional clinical interventions to maintain stability.

The cardiology team quickly proceeds with angiography, which reveals a significant occlusion in the left anterior descending artery, confirming the diagnosis of a STEMI. In response, an urgent decision is made to perform percutaneous coronary intervention (PCI) to restore coronary blood flow. The nursing team plays a critical role in preparing the patient for the procedure, ensuring that intravenous access is secured, and all necessary consent forms are reviewed and signed. They also provide reassurance to the patient, explaining the steps of the procedure to alleviate his anxiety.

During the PCI, the patient experiences transient episodes of ventricular arrhythmias, likely due to reperfusion injury as blood flow is restored to the ischemic myocardium. These episodes necessitate swift intervention with antiarrhythmic medications and continuous ECG monitoring. The nursing team remains alert to these developments, ready to implement advanced cardiac life support protocols if needed. This phase of the patient’s care underscores the importance of dynamic clinical reasoning and the ability to anticipate and manage potential complications, ensuring that the patient's transition through the acute phase of his myocardial infarction is as smooth as possible.

Section 4

Following the successful PCI, the patient's hemodynamic status initially shows signs of improvement. His heart rate stabilizes at around 90 beats per minute, and his blood pressure returns to a more reassuring level of 140/90 mmHg. Oxygen saturation gradually improves to 93% on high-flow oxygen, and his respiratory rate decreases to 22 breaths per minute. However, despite these improvements, the patient reports persistent chest discomfort and increasing shortness of breath. Concerned about these symptoms, the nursing team conducts a thorough assessment and gathers new diagnostic results to guide further interventions.

A repeat ECG shows the resolution of ST-segment elevation, suggesting successful reperfusion; however, new T-wave inversions and the presence of Q waves indicate the potential for ongoing myocardial damage. Blood tests reveal elevated troponin levels, consistent with myocardial injury, and a significant rise in B-type natriuretic peptide (BNP), indicating stress on the heart and possible heart failure. The nursing team also notices diminished breath sounds and dullness to percussion over the lower lung fields, raising the suspicion of developing pulmonary congestion or pleural effusion as a complication of the myocardial infarction.

With these new findings, the clinical team must reconsider their management strategy. The priority shifts towards optimizing cardiac function and preventing further complications. Diuretics are introduced to address fluid overload and alleviate pulmonary symptoms. The nursing team closely monitors the patient's fluid balance and renal function, recognizing the risk of acute kidney injury due to diuretic therapy. These developments highlight the need for vigilant clinical reasoning, as the team works to stabilize the patient's condition while remaining alert to the potential for further complications as he transitions into the recovery phase.

Section 5

As the patient continues to be monitored, the nursing team records a gradual decline in his respiratory status. Despite the administration of diuretics, the patient reports worsening shortness of breath and displays increased use of accessory muscles during respiration. His oxygen saturation begins to drop to 88% on high-flow oxygen, indicating the need for further intervention. The team promptly calls for a chest X-ray, which reveals bilateral pleural effusions and further signs of pulmonary edema, suggesting that the heart failure may be more severe than initially anticipated.

In response to these findings, the clinical team adjusts the patient's management plan to include the initiation of non-invasive positive pressure ventilation (NIPPV) to support his breathing and improve oxygenation. The patient is placed on continuous positive airway pressure (CPAP) to help reduce the work of breathing and facilitate the reabsorption of pulmonary edema. Meanwhile, the patient's vital signs are closely monitored: his heart rate remains at 92 beats per minute, but there is a noticeable increase in blood pressure to 150/96 mmHg, potentially indicating heightened sympathetic activity or fluid redistribution.

This shift in the patient's condition prompts the healthcare team to explore further therapeutic options, including optimizing his medication regimen to manage heart failure more effectively. The possibility of transitioning to intravenous vasodilators is considered to reduce cardiac preload and afterload, while ensuring renal function remains stable. As the patient navigates these challenges, the team emphasizes the importance of continuous reassessment and adjustment of care plans, recognizing the delicate balance required to optimize outcomes and prevent further decompensation.
