Shanghai General Hospital Successfully Treats a Patient with Complex, Severe Pulmonary Hypertension and Multiple Comorbidities

The cardiology team at Shanghai General Hospital has successfully identified a previously overlooked factor contributing to the deterioration of a 72-year-old patient with severe pulmonary hypertension and multiple underlying conditions. Through meticulous clinical assessment and a comprehensive, integrated treatment strategy, the team achieved significant symptom relief and a substantial improvement in the patient’s quality of life.

Ms. Wu (pseudonym), 72, had suffered from persistent chest tightness and shortness of breath for years, with severely limited exercise tolerance and daily functioning. Her medical history included both mitral and aortic valve replacement, as well as pacemaker implantation. She was also taking multiple medications and had coexisting hypertension and diabetes, making her case considerably more complex than that of a typical patient.

Over the preceding three months, her chest tightness and breathlessness had progressively worsened, and her exercise tolerance had declined dramatically. She eventually became unable to manage even basic daily activities independently. Her husband accompanied her to several hospitals in search of treatment, but the complexity of her condition and the limited anticipated benefits of available interventions meant that no effective, comprehensive management plan was established. As her condition continued to deteriorate, she also became increasingly discouraged.

When Ms. Wu presented to the Department of Cardiology at Shanghai General Hospital, Associate Chief Physician Jiang Rong conducted a detailed review of her medical history. She suspected that the patient had severe pulmonary hypertension and recommended hospitalization for a systematic evaluation to identify any underlying causes that might have been overlooked.

Following admission, the clinical team performed right heart catheterization, the gold standard for assessing the hemodynamic status of pulmonary hypertension. This procedure enables precise measurement of pulmonary artery pressure, pulmonary vascular resistance, and cardiac output, providing essential information for diagnosis and treatment planning.

The right heart catheterization results were as follows: pulmonary artery pressure, 61/15/32 mmHg; pulmonary artery wedge pressure, 19/11/13 mmHg; cardiac output, 5.3 L/min; cardiac index, 3.66 L/min/m²; and pulmonary vascular resistance, 3.58 Wood units.

Based on these findings and the patient’s clinical presentation, the team initially considered post-capillary pulmonary hypertension. Further assessment of her clinical features and hemodynamic profile led to a final diagnosis of pulmonary hypertension associated with left heart disease, with a combined hemodynamic component.

The team did not stop at this initial diagnosis. During a comprehensive review of the patient’s laboratory and diagnostic results, one finding immediately raised concern: her hemoglobin level was just 6.3 g/dL. After integrating this result with other laboratory findings, the team diagnosed severe iron-deficiency anemia.

This discovery proved pivotal in understanding the complexity of her condition. Severe anemia can cause tissue hypoxia and markedly reduce exercise tolerance. More importantly, it increases cardiac workload, potentially aggravating pulmonary hypertension and heart failure. In turn, heart failure and impaired oxygen delivery can further worsen the patient’s overall condition, creating a vicious cycle that compounds disease severity.

The team also identified severe gout, which required simultaneous consideration as part of the patient’s overall treatment strategy. Addressing this additional condition was essential to achieving coordinated, multidimensional care.

Following a comprehensive assessment, the team developed an integrated treatment plan targeting the patient’s pulmonary hypertension, severe iron-deficiency anemia, and gout.

For the severe iron deficiency, the team selected intravenous ferric carboxymaltose, an iron replacement therapy supported by substantial clinical evidence and guideline recommendations for iron deficiency in patients with heart failure. The aim was to replenish iron stores promptly, improve oxygen delivery to tissues, and help interrupt the vicious cycle linking anemia, heart failure, and pulmonary hypertension.

To manage the patient’s severe gout, the team administered Firsekibart, which precisely blocks the IL-1β inflammatory pathway to rapidly control acute attacks, achieve long-lasting anti-inflammatory effects, reduce the risk of recurrence, and exert potential multi-organ protective effects.

At the same time, the team continued appropriate assessment and management of her pulmonary hypertension, maintaining targeted therapy as clinically indicated. By addressing the coexisting conditions alongside the underlying cardiovascular disease, the team pursued a coordinated, whole-patient approach designed to improve overall prognosis and quality of life.

The results were encouraging. Within just one week, Ms. Wu showed a marked improvement in exercise tolerance and cardiac function, helping her regain confidence in daily life. Follow-up assessments subsequently showed a steady rise in hemoglobin levels, effective control of pulmonary hypertension, normalization of serum uric acid, and complete resolution of gout symptoms.

This case highlights the importance of precise hemodynamic assessment and comprehensive clinical reasoning in the diagnosis and management of pulmonary hypertension. Right heart catheterization established the hemodynamic profile of the disease, while comprehensive laboratory screening uncovered a key contributing factor that might otherwise have been missed. Comorbidities that appear unrelated to the primary diagnosis can sometimes play a central role in disease progression.

The Department of Cardiology at Shanghai General Hospital will continue to uphold a precision-medicine approach, applying systematic clinical reasoning to complex and challenging cardiovascular cases and providing professional, patient-centered care to safeguard cardiovascular health.
