What is Coronary Stent Thrombosis?

Coronary stent thrombosis is the acute thrombotic occlusion of an implanted stent after percutaneous coronary intervention. It is classified by timing as acute (within 24 hours), subacute (1–30 days), late (up to 1 year) and very late (beyond 1 year).

Early discontinuation of dual antiplatelet therapy is the most important risk factor. Mechanical factors such as stent underexpansion, residual dissection, small vessel size and long stents also contribute.

It frequently presents as ST-elevation myocardial infarction and requires emergency reintervention. Because mortality is high, prevention is more important than treatment.

Symptoms

Sudden typical chest pain
ST elevation on ECG
Cold diaphoresis and weakness
Signs of heart failure
Cardiogenic shock
Nausea and vomiting
Pain lasting more than 20 minutes

Risk Factors

Early discontinuation of dual antiplatelet therapy
Stent underexpansion
Small vessel diameter and long stent length
Residual dissection
Low ejection fraction
Diabetes and chronic kidney disease
Clopidogrel resistance

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • New chest pain after stenting
  • Non-adherence to dual antiplatelet therapy
  • Preoperative interruption of antiplatelet therapy
  • Sudden signs of heart failure

Treatment Methods

01
Emergency primary percutaneous coronary intervention
02
Intensive antiplatelet and anticoagulant therapy
03
Additional stenting or balloon angioplasty when needed
04
Thrombectomy
05
Intensive care monitoring
06
Long-term dual antiplatelet therapy planning

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
