The presentation of sudden shortness of breath, pleuritic chest pain, palpitations, and the recent discovery of atrial fibrillation with right ventricular strain patterns in a 65-year-old postoperative patient strongly suggests a pulmonary embolism (PE). Understanding the underlying pathophysiologic processes involved provides crucial insight into why these symptoms manifest and how they are interconnected, especially considering potential racial and ethnic influences on physiological response.

Pulmonary embolism is primarily caused by a thrombus, often originating from deep veins in the lower extremities, which dislodges and occludes pulmonary arteries. This blockage impairs pulmonary blood flow, leading to increased pulmonary vascular resistance and elevated pulmonary artery pressures. Consequently, the right ventricle faces increased afterload, which can cause right ventricular dilation and strain, observable on an EKG as T wave inversions in right precordial and inferior leads. The right ventricular strain pattern reflects the heart's response to increased pressure load due to pulmonary arterial obstruction, correlating with clinical signs of dyspnea and chest pain, especially on exertion or respiration (Goldhaber et al., 2019).

Cardiovascularly, the acute increase in pulmonary pressures results in decreased cardiac output and impaired oxygenation, further exacerbating hypoxia. The hypoxic environment stimulates pulmonary vasoconstriction, worsening the burden on the right ventricle. Alterations in the atrial conduction pathways caused by atrial fibrillation can lead to irregular ventricular response, reducing efficient cardiac output. This arrhythmia may be precipitated by atrial stretch or ischemia, both of which can occur with pulmonary hypertension. The combination of hypoxia, right ventricular strain, and atrial fibrillation collectively diminishes systemic oxygen delivery, contributing to the patient's symptoms (Koumantarakis et al., 2020).

Regarding racial and ethnic variables, research indicates that genetic predispositions, environmental factors, and disparities in healthcare access influence physiological responses. For instance, African American populations have been documented to have a higher baseline risk for thrombotic events, including PE, due to genetic factors such as elevated levels of clotting factors and differences in the fibrinolytic system (Miller et al., 2018). Additionally, disparities in healthcare access and preventative care can delay diagnosis and treatment, aggravating outcomes. These variables can modify the severity of the response to embolic events and influence recovery trajectories.

The interaction between the cardiopulmonary processes in this scenario culminates in a complex cascade that impairs oxygenation and cardiac efficiency. The thrombotic event impairs pulmonary circulation, leading to right ventricular strain, which triggers atrial fibrillation. This arrhythmia compromises stroke volume and worsens hypoxia, further stressing the cardiovascular system. The resultant symptoms of chest pain, shortness of breath, and palpitations are manifestations of this interconnected pathophysiological disturbance. Recognition of racial and ethnic factors plays a crucial role in risk stratification, personalized management, and improving health outcomes in diverse populations. Therefore, immediate diagnostic evaluation and tailored treatment are necessary to mitigate morbidity and prevent mortality associated with pulmonary embolism in postoperative patients (Jaff et al., 2019).
