腕管综合征治疗指南：选择、自我护理和康复

Overview

Pericarditis is inflammation of the pericardium, the thin, double-layered sac that surrounds and protects your heart. When this sac becomes inflamed, the layers can rub against each other, causing pain and sometimes fluid buildup (pericardial effusion). Acute pericarditis usually lasts a few days to weeks and often improves with treatment. Some people experience recurrent episodes. It can affect people of any age but is more common in young adults and men.

Most cases are not life-threatening when recognized and managed promptly. However, complications such as large fluid collections or constriction of the heart can occur and need medical attention.

Signs & Symptoms

The classic symptom is sharp, stabbing chest pain that may feel better when sitting up and leaning forward, and worse when lying down or taking a deep breath. Other common signs include:

• Chest pain that can radiate to the neck, shoulders, or back
• Low-grade fever
• Shortness of breath, especially when reclining
• Heart palpitations or a rapid heartbeat
• Fatigue or general feeling of being unwell
• Dry cough
• Swelling in the legs or abdomen in more severe or chronic cases

Causes & Risk Factors

Often the exact cause is unknown (idiopathic). Many cases follow a viral infection. Other causes and risk factors include:

• Viral infections (most common identifiable cause)
• Bacterial, fungal, or other infections (less common)
• Autoimmune conditions such as lupus or rheumatoid arthritis
• Heart attack or heart surgery (post-cardiac injury)
• Kidney failure or certain cancers
• Chest injury or radiation therapy to the chest
• Certain medications
• Male sex and younger adult age

Diagnosis

Your doctor will take a history, listen to your heart (a characteristic friction rub may be heard), and order tests. Common evaluations include:

• Electrocardiogram (ECG or EKG) to look for typical electrical changes
• Blood tests for inflammation markers (such as CRP or ESR) and to check for infection or heart muscle injury
• Chest X-ray
• Echocardiogram (ultrasound of the heart) to assess fluid around the heart and heart function
• CT or MRI of the heart in selected cases
• Sometimes pericardiocentesis (fluid sampling) if infection or other specific causes are suspected

Treatment & Management

Treatment focuses on reducing inflammation, relieving pain, treating the underlying cause when known, and preventing complications. Most people with uncomplicated acute pericarditis are managed as outpatients.

• Rest and activity restriction until pain and inflammation improve
• Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or high-dose aspirin as first-line therapy
• Colchicine often added to reduce recurrence risk and speed recovery
• Corticosteroids (such as prednisone) reserved for cases that do not respond to NSAIDs/colchicine or when there is a specific indication (e.g., autoimmune disease)
• Antibiotics or other targeted therapy if an infectious cause is identified
• Hospital care, drainage of fluid, or rarely surgery for large effusions, tamponade, or constrictive pericarditis

Your doctor will tailor medicines to your situation, monitor for side effects (especially stomach protection with NSAIDs), and schedule follow-up to confirm improvement. Do not stop prescribed medicines early without medical advice.

Living With It

Most people recover fully from a first episode of acute pericarditis within a few weeks. Recurrence can happen in some individuals; colchicine and careful follow-up help lower this risk. Lifestyle steps support healing: prioritize rest initially, gradually return to activity as cleared by your doctor, manage any underlying conditions, avoid smoking, and keep follow-up appointments. Emotional support matters—chest pain can be frightening, so talk with your care team about concerns. Long-term outlook is generally good with proper management.
