Management of High-Risk Patients with Suspected Acute Coronary Syndrome

Critical Next Steps

The European Society of Cardiology recommends hospitalization in a high-dependency unit for patients with suspected acute coronary syndrome and high-risk features, including recent acute kidney injury and coronary artery disease with prior percutaneous coronary intervention 1, 2
Measurement of arterial blood gases with pH, PaCO2, and lactate is recommended for patients with a history of chronic obstructive pulmonary disease and recent respiratory issues, as suggested by the European Heart Journal 3, 1, 2
Continuous pulse oximetry is a Class I recommendation for patients with acute heart failure or respiratory distress, according to the European Heart Journal 3, 1

The American Journal of Respiratory and Critical Care Medicine recommends assessing for signs of acute chronic obstructive pulmonary disease exacerbation, including increased dyspnea, sputum volume, and purulence 4
Non-invasive positive pressure ventilation, such as bi-level positive airway pressure, is recommended for patients with respiratory distress and hypercapnia, as suggested by the European Heart Journal 3, 1, 2, 7
Controlled oxygen therapy should be provided to maintain an oxygen saturation of 90% or higher, while avoiding hyperoxia, according to the European Heart Journal 3, 1, 2, 7

The European Heart Journal suggests that patients with elevated troponin levels and suspected acute coronary syndrome should undergo urgent coronary angiography within 24-48 hours 1, 2
The American Journal of Respiratory and Critical Care Medicine recommends initiating or increasing short-acting bronchodilators for patients with chronic obstructive pulmonary disease exacerbation 4
Systemic corticosteroids, such as prednisone, may be considered for patients with moderate-to-severe chronic obstructive pulmonary disease exacerbation, as suggested by the American Journal of Respiratory and Critical Care Medicine and the European Respiratory Journal 4, 6

The European Heart Journal recommends hospitalization for patients with suspected acute coronary syndrome and high-risk features, including recent acute kidney injury and coronary artery disease with prior percutaneous coronary intervention 1, 2
Admission to a high-dependency unit is recommended for patients with persistent significant dyspnea, potential acute coronary syndrome, and multiple comorbidities, as suggested by the European Heart Journal and the American Journal of Respiratory and Critical Care Medicine 1, 2, 4
