Blood clots are the body’s natural way of preventing bleeding. However, when clots form inside the heart or blood vessels without injury, they can be dangerous — even life-threatening. Early detection is crucial, especially when blood clots form in or around the heart, as they can lead to serious conditions like heart attacks, strokes, or pulmonary embolisms.
In this blog, we’ll explore:
- What blood clots in the heart are
- Early warning signs and symptoms
- Who is at risk
- How they’re diagnosed and treated
What Is a Blood Clot in the Heart?
A blood clot (thrombus) in the heart is a mass of blood cells that clumps together in a chamber of the heart or in a nearby artery. When these clots form improperly or fail to dissolve, they can block blood flow, leading to a heart attack or causing the clot to travel to the brain (stroke) or lungs (pulmonary embolism).
Why Are Blood Clots in the Heart Dangerous?
Blood clots can:
- Obstruct the coronary arteries, which supply oxygen-rich blood to the heart muscle
- Cause atrial fibrillation-related clots, which can travel from the heart to the brain
- Lead to heart failure, stroke, or sudden cardiac arrest if untreated
Early-Stage Symptoms of Blood Clots in the Heart
Blood clots often start with subtle symptoms. Recognizing them early can prevent severe damage.
1. Chest Discomfort or Pain
- A heavy, tight, or squeezing sensation in the chest
- Often mistaken for indigestion or muscle strain
- May radiate to the left arm, neck, or jaw
💡 This could be a sign of a clot blocking a coronary artery, leading to a heart attack.
2. Shortness of Breath
- Feeling winded or breathless even at rest or with mild activity
- May worsen when lying down
🫁 Could indicate reduced oxygen due to a clot affecting heart or lung circulation.
3. Irregular or Rapid Heartbeat (Palpitations)
- Feeling like your heart is racing, skipping beats, or fluttering
- Common in atrial fibrillation, which can lead to clot formation in the heart’s upper chambers
4. Sudden Fatigue or Weakness
- Overwhelming tiredness unrelated to physical activity
- May be accompanied by light-headedness or dizziness
🧠 Could signal that the heart isn’t pumping efficiently due to a clot.
5. Swelling in Legs, Ankles, or Abdomen
- Caused by poor circulation from a clot in the heart or deep veins
- Often one-sided leg swelling with pain or tenderness
🚨 Might be a deep vein thrombosis (DVT), which can travel to the heart or lungs.
6. Persistent Cough or Wheezing
- Especially if coughing up blood-tinged mucus
- May indicate a pulmonary embolism, a clot that has moved from the heart or veins to the lungs
7. Sudden Cold Sweats or Nausea
- Can resemble flu-like symptoms
- When paired with chest pain, it may be a red flag for heart attack due to a clot
Who’s at Risk for Heart Blood Clots?
You may be more vulnerable to cardiac blood clots if you have:
- Atrial fibrillation (irregular heart rhythm)
- Coronary artery disease (CAD)
- Heart failure
- Recent heart surgery or valve replacement
- Obesity or sedentary lifestyle
- Smoking, diabetes, or high blood pressure
- Cancer or autoimmune diseases
- History of blood clotting disorders
How Are Heart Clots Diagnosed?
Early detection can save your life. Common diagnostic tests include:
- Electrocardiogram (ECG) – Checks for abnormal heart rhythms
- Echocardiogram (ECHO) – Uses ultrasound to visualize clots in heart chambers
- Cardiac MRI or CT scan – Detailed imaging of the heart and vessels
- D-dimer blood test – Measures clotting activity
- Angiography – Detects blockages in arteries
Treatment Options
Depending on the location and size of the clot, your doctor may recommend:
1. Blood Thinners (Anticoagulants)
- Prevent new clots and stop existing ones from growing
- Common drugs: Warfarin, Heparin, DOACs (Eliquis, Xarelto)
2. Clot-Busting Medications (Thrombolytics)
- Used in emergency cases like heart attacks or strokes
3. Surgical Procedures
- Catheter-based clot removal
- Coronary angioplasty or bypass surgery in case of blocked arteries
4. Lifestyle Changes
- Regular exercise, a heart-healthy diet, quitting smoking, and managing weight
When to Seek Emergency Help
Call emergency services immediately if you experience:
- Sudden chest pain
- Difficulty breathing
- Rapid or irregular heartbeat
- Swelling in one leg with pain
- Unexplained fatigue or fainting
🧠 Time = Muscle: The earlier a blood clot is detected and treated, the better your chances of recovery.
Preventing Blood Clots in the Heart
Take these simple yet powerful steps:
- Stay physically active
- Take medications as prescribed (especially for AFib or heart conditions)
- Stay hydrated
- Avoid prolonged sitting (especially during travel)
- Regular heart checkups if you’re at risk
