Chest pain pericarditis - Nursing Case Study

Pathophysiology

• Primary mechanism: Inflammation of the pericardium leads to irritation of the parietal pericardium, which is innervated by the phrenic nerve, causing sharp, pleuritic chest pain that often worsens with inspiration or when lying supine.

• Secondary mechanism: The inflammatory process may result in increased pericardial fluid secretion, causing an effusion that exerts pressure on the heart, potentially compromising cardiac function and leading to pain due to ischemia-like symptoms.

• Key complication: If pericardial effusion progresses to cardiac tamponade, the pressure can severely restrict heart filling during diastole, resulting in decreased cardiac output, hemodynamic instability, and life-threatening complications such as shock or cardiac arrest.

Section 1

As the healthcare team initiates further evaluation, additional diagnostic tests are performed to assess the severity and implications of the patient's condition. An echocardiogram reveals a significant pericardial effusion exerting pressure on the heart, consistent with early signs of cardiac tamponade. The inferior vena cava appears dilated and non-collapsible, indicating elevated central venous pressure. Electrocardiogram shows diffuse ST segment elevations, consistent with pericarditis, but also new PR segment depressions, suggesting increasing pericardial irritation.

Laboratory results reveal elevated inflammatory markers, including a C-reactive protein level of 30 mg/L and an erythrocyte sedimentation rate of 85 mm/hr, confirming ongoing inflammation. Cardiac biomarkers show elevated troponin I levels at 0.9 ng/mL, indicating myocardial strain, likely due to compromised coronary perfusion from the effusion. Additionally, the patient's renal function tests reveal a creatinine level of 2.1 mg/dL, suggesting acute kidney injury, possibly due to decreased renal perfusion or diabetic nephropathy exacerbation.

Upon re-evaluation, the patient's condition deteriorates; he becomes increasingly diaphoretic and confused, with a marked drop in blood pressure to 78/46 mmHg and heart rate increasing to 140 bpm. Pulsus paradoxus is noted on physical examination. The immediate priority is to address the hemodynamic instability and prevent progression to full cardiac tamponade. The clinical team urgently prepares for pericardiocentesis to relieve the pressure on the heart while simultaneously considering advanced interventions such as initiating vasopressor support to stabilize blood pressure. The unfolding complexity requires advanced clinical judgment to balance immediate life-saving interventions with managing underlying chronic conditions, ensuring a comprehensive approach to the patient's increasingly precarious clinical status.

Section 2

As the clinical team initiates pericardiocentesis, they are acutely aware of the precariousness of the situation, given the signs of impending cardiac tamponade. The procedure is performed under ultrasound guidance, and approximately 300 mL of serous fluid is aspirated from the pericardial space. Almost immediately, there is a transient improvement in the patient's hemodynamics; blood pressure rises to 92/58 mmHg, and heart rate decreases to 120 bpm. However, the relief is short-lived. Within the hour, the patient begins to exhibit signs of respiratory distress, with a respiratory rate climbing to 32 breaths per minute and an oxygen saturation dropping to 88% on room air. Auscultation of the lungs reveals new bilateral crackles, raising concerns for acute pulmonary edema.

The team quickly reassesses the patient, considering the possibility of volume overload exacerbated by aggressive fluid resuscitation earlier, combined with a compromised cardiac output. Repeat laboratory tests show a further increase in creatinine to 2.8 mg/dL, indicating worsening renal function, likely secondary to both decreased perfusion and now possible contrast-induced nephropathy from recent imaging. The patient’s mental status remains altered, with a Glasgow Coma Scale score of 12, indicating moderate impairment. The decision is made to initiate non-invasive positive pressure ventilation to address the respiratory insufficiency, while simultaneously starting a low-dose norepinephrine infusion to maintain adequate mean arterial pressure and support organ perfusion.

As the patient's journey continues, the team must balance the immediate need to stabilize his respiratory and cardiovascular status with the necessity of addressing the underlying inflammatory process and potential infectious etiology of the pericarditis. This juncture requires a careful examination of potential etiologies, including viral, bacterial, or autoimmune causes, and consideration of starting broad-spectrum antibiotics empirically, given the high inflammatory markers and potential for systemic infection. The unfolding complexity challenges the team to integrate multisystem management strategies while continually reassessing the patient's response to each intervention and adapting the care plan accordingly.

Section 3

As the team continues to manage the complex clinical scenario, they observe a change in the patient’s status that warrants immediate attention. Despite the initiation of non-invasive positive pressure ventilation and norepinephrine infusion, the patient's respiratory distress worsens. His oxygen saturation continues to decline, now reaching 82% on BiPAP, and he exhibits increased agitation and confusion, suggesting hypoxic encephalopathy. Auscultation reveals worsening crackles and the emergence of wheezing, indicating possible bronchospasm or further pulmonary compromise. Concurrently, his blood pressure remains tenuous at 86/54 mmHg despite the vasopressor support, and his heart rate climbs back to 130 bpm, suggesting inadequate circulatory support.

Repeat arterial blood gases indicate a mixed respiratory and metabolic acidosis, with a pH of 7.25, PaCO2 of 55 mmHg, and HCO3- of 18 mmol/L. Lactate levels have risen to 4.5 mmol/L, indicating ongoing tissue hypoperfusion. This constellation of findings prompts the team to consider escalating respiratory support to invasive mechanical ventilation, acknowledging the risks of sedation and potential loss of airway reflexes in the context of his altered mental status. In parallel, additional diagnostic imaging, such as a chest CT, is ordered to evaluate for potential pulmonary embolism or other structural causes of the respiratory decompensation, while carefully weighing the risk of further nephrotoxic contrast exposure.

As they prepare for these interventions, the team also discusses the necessity of refining the differential diagnosis for the underlying cause of the pericarditis. Given the acute deterioration and high inflammatory markers, consensus leans towards initiating broad-spectrum antibiotics to cover possible bacterial causes while awaiting further culture results. The complexity of the case now demands a multidisciplinary approach, with intensivists, cardiologists, nephrologists, and infectious disease specialists collaborating closely to prioritize interventions and anticipate potential complications. The goal is to stabilize the patient’s hemodynamics and respiratory status while advancing the diagnostic workup to pinpoint the underlying pathology.

Section 4

As the team advances in managing the patient's critical condition, they prioritize obtaining a chest CT to elucidate the cause of his rapid respiratory and hemodynamic deterioration. The imaging reveals signs consistent with acute pulmonary edema, likely secondary to acute left ventricular dysfunction, which had been masked by the initial diagnosis of pericarditis. Notably, there is also evidence of bilateral pleural effusions and atelectasis, complicating the respiratory picture further. No obvious pulmonary embolism is detected, but the extent of the pulmonary compromise necessitates immediate action. Given the imaging findings, the differential diagnosis expands to consider acute myocarditis or a severe exacerbation of his pericarditis with cardiac tamponade as potential contributors to his acute heart failure and respiratory distress.

In response to the new diagnostic insights, the team decides to initiate diuresis with intravenous furosemide to address the volume overload contributing to pulmonary edema. They also consider introducing inotropic support with dobutamine to improve cardiac output, mindful of the patient's tenuous blood pressure and the potential for further hemodynamic instability. Despite these interventions, the patient’s clinical status remains precarious, with his oxygen saturation fluctuating between 80-85% even after intubation and initiation of mechanical ventilation. His blood pressure shows minimal improvement, hovering around 90/56 mmHg, and his heart rate remains elevated at 125 bpm.

Meanwhile, the multidisciplinary team contemplates the next steps in the diagnostic workup and management. Given the high suspicion of myocarditis, an endomyocardial biopsy is proposed to obtain definitive histological confirmation, while cardiac MRI could provide additional non-invasive insights into myocardial inflammation. The potential for underlying infectious causes of myocarditis prompts a reevaluation of the antibiotic regimen, ensuring coverage for atypical pathogens. As the patient continues to be critically unstable, the team remains vigilant for signs of further decompensation, including refractory shock or arrhythmias, that may necessitate advanced hemodynamic support, such as extracorporeal membrane oxygenation (ECMO), to provide a bridge until a definitive diagnosis and targeted treatment can be effectively established.

Section 5

As the multidisciplinary team proceeds with the management of this complex case, they receive new diagnostic results from the cardiac MRI, which reveals diffuse myocardial edema and late gadolinium enhancement consistent with acute myocarditis. Additionally, the endomyocardial biopsy confirms lymphocytic infiltration, further solidifying the diagnosis of myocarditis. These findings prompt a reconsideration of the patient's treatment regimen, particularly focusing on managing the inflammatory process driving his cardiac dysfunction. High-dose intravenous corticosteroids are initiated, aiming to reduce myocardial inflammation and improve cardiac function. However, the team remains cautious, aware of the potential immunosuppressive effects and the risk of secondary infections, thus necessitating close monitoring and possibly further adjustments to antimicrobial coverage.

Despite these targeted interventions, the patient's clinical status changes, indicating a new complication potentially complicating his trajectory. He develops acute renal failure, likely secondary to a combination of factors including low cardiac output and the nephrotoxic effects of furosemide. This renal compromise is reflected in his laboratory values, with a serum creatinine climbing from 1.2 mg/dL to 3.6 mg/dL within 24 hours, and a marked reduction in urine output. The worsening renal function poses a significant challenge, necessitating a delicate balance between maintaining adequate perfusion and avoiding fluid overload. The team considers continuous renal replacement therapy (CRRT) as a potential strategy to manage fluid balance and mitigate further renal damage, while ensuring optimal hemodynamic support.

As the patient's condition teeters on the edge of stability, the team is faced with complex decision-making scenarios that require advanced clinical reasoning and judgment. They must weigh the risks and benefits of immunosuppressive therapy against the potential for opportunistic infections, monitor for signs of refractory shock despite current hemodynamic support, and consider the timing and appropriateness of implementing CRRT. These considerations highlight the delicate interplay between aggressive treatment and the prevention of further complications, underscoring the critical need for ongoing reassessment and adaptability in the management plan. The patient's journey exemplifies the complexity of acute care in the setting of overlapping cardiopulmonary and renal dysfunction, demanding meticulous attention to evolving clinical data and a coordinated, multidisciplinary approach.
