Acute Pulmonary Embolism: Symptoms, Diagnosis, and Treatment - Cardiology

More Info

---

Acute pulmonary embolism (PE) is a serious condition that occurs when a blood clot blocks one or more pulmonary arteries in the lungs. This blockage can lead to significant complications, including reduced blood flow to the lungs, decreased oxygen levels in the blood, and strain on the heart. The symptoms of acute pulmonary embolism can vary widely, but common manifestations include sudden shortness of breath, chest pain (which may feel like a heart attack), rapid heart rate, and sometimes coughing up blood.
In your case, the routine chest CT scan revealed significant filling defects in both pulmonary arteries, indicating the presence of bilateral pulmonary thromboembolism. The dilated right atrium (RA) and right ventricle (RV) noted in the imaging suggest that your heart is under strain due to the increased pressure from the blocked pulmonary arteries. The absence of pleural effusion and enlarged lymph nodes is reassuring, as it indicates that there are no additional complications such as fluid accumulation or malignancy at this time.

Following your hospitalization and treatment with anticoagulants, it is not uncommon to continue experiencing symptoms such as chest discomfort, shortness of breath, and dizziness. The medications you are currently taking, including rivaroxaban (普栓達), are designed to prevent further clot formation and allow your body to gradually dissolve the existing clots. However, the resolution of symptoms can take time, and it is important to be patient as your body heals.

Your reported oxygen saturation levels between 88-93% are concerning, as they indicate that your blood oxygen levels are lower than the normal range (typically 95-100%). This can contribute to feelings of breathlessness and dizziness. It is crucial to monitor these levels closely and report any significant changes to your healthcare provider. Deep breathing exercises may help alleviate some discomfort, but if you experience increased pain or difficulty breathing, you should seek immediate medical attention.

In terms of follow-up care, it is essential to maintain regular appointments with your healthcare provider to monitor your progress. They may recommend additional imaging studies or pulmonary function tests to assess your lung capacity and overall respiratory function. If your symptoms persist or worsen, further evaluation may be necessary to rule out other potential complications, such as chronic thromboembolic pulmonary hypertension (CTEPH), which can occur in some patients after a PE.

In summary, acute pulmonary embolism is a serious condition that requires careful management and follow-up. While it is normal to experience lingering symptoms after treatment, it is vital to stay in close communication with your healthcare team and adhere to prescribed medications. If you have any concerns about your symptoms or treatment plan, do not hesitate to reach out to your doctor for guidance. Your health and well-being are paramount, and proactive management is key to recovery.
