Abstract

Non-atherosclerotic acute coronary syndrome (ACS) refers to a group of conditions that cause myocardial damage and clinical symptoms like traditional ACS but are not primarily caused by coronary artery plaque rupture or obstruction. This abstract provides an overview of the etiology, clinical presentation, diagnosis, and management of non-atherosclerotic ACS. Several etiologies can lead to non-atherosclerotic ACS, including coronary artery vasospasm, connective tissue disorders, stress-induced cardiomyopathy (Takotsubo syndrome), and vasculitis. The clinical presentation can mimic traditional ACS, with chest pain being the most common symptom. Diagnostic tools such as electrocardiography (ECG), laboratory biomarkers, echocardiography, coronary angiography, cardiac magnetic resonance imaging (MRI), and nuclear imaging play a crucial role in distinguishing non-atherosclerotic ACS from traditional ACS. Treatment strategies for non-atherosclerotic ACS are often based on expert consensus and clinical experience due to the lack of specific guidelines. Management approaches depend on the underlying etiology and may include pharmacological therapy, invasive interventions such as percutaneous coronary intervention (PCI) or surgery, and risk factor modification. Prompt diagnosis and appropriate management are crucial for improving patient outcomes. Further research and prospective studies are needed to enhance our understanding of non-atherosclerotic ACS and optimize its management.

Abstract

Acute Heart Failure (AHF) can affect carbon dioxide levels in the body by altering the balance between ventilation and carbon dioxide production, leading to either hypocapnia or hypercapnia. Arterial carbon dioxide (CO2) levels are essential for maintaining respiratory function and acid-base balance. However, the relationship between arterial CO2 levels and AHF remains complex and not fully understood. Diverse factors affect arterial CO2 levels in patients with AHF, including neurohormonal activation, respiratory compensation for hypoxemia, and changes in pulmonary perfusion. Hypocapnia, characterized by low arterial CO2 levels (PaCO2 < 35 mmHg), is commonly observed in AHF due to hyperventilation-driven respiratory alkalosis secondary to pulmonary congestion. It showed a strong connection with the survival rates of patients following a cardiac arrest. Nevertheless, elevated levels of carbon dioxide in the blood, known as hypercapnia, with a partial pressure of arterial carbon dioxide (PaCO2) exceeding 45 mmHg, can also arise in the later phases of acute heart failure (AHF), indicating fatigue in respiratory muscles or deterioration in pulmonary edema. Abnormal arterial CO2 levels have been associated with increased morbidity and mortality in AHF patients, serving as a valuable prognostic marker.

Abstract

Background: Patients with AHF may experience fluctuations in carbon dioxide levels, resulting in either hypercapnia or hypocapnia. Recent research has highlighted the significance of the relationship between CO2 fluctuation and patient outcomes. Objective: The aim of this study was to explore the relationship between arterial carbon dioxide pressure (PaCO2) upon admission to the ICCU in patients with AHF. Methods: A single centre retrospective observational study was performed, the patient were enrolled from patient medical record between 2021 and 2023. Participants were divided into three groups based on PaCO2 levels. The study end point was length of hospitalization, mortality at ICCU and mortality in hospital. Statistical analysis used various tests to compare outcomes, with significance set at p<0.05, and ROC analysis evaluated mortality prediction. Result: The study included 150 patients: 97 with hypocapnia, 33 with normal PaCO2, and 19 with hypercapnia. In-hospital mortality was 37.5%, and 1-month mortality was 33.3% in the hypercapnia group. PaCO2 >45 mmHg was linked to higher in-hospital mortality (OR 6.900, p <0.001) and 30-day mortality (OR 5.600, p <0.001), PaCO2 <35 mmHg showing a protective association in ICCU and in-hospital mortality (OR 0.202, p<0.001) and 30-day mortality (OR 0.237, p<0.001). Length of stay was not significantly affected by either hypocapnia or hypercapnia. The ROC for predicting in-hospital mortality was 0.648 and for 30-day mortality was 0.626 in the PaCO2 >45 mmHg group. Conclusion: PaCO2 levels at ICCU admission predict mortality in AHF patients. Hypercapnia is associated with higher in-hospital and 30-day mortality, while hypocapnia appears protective.
