A heart blockage occurs when fatty deposits called plaque build up inside the coronary arteries, narrowing them and restricting blood flow to the heart muscle. This condition, known as atherosclerosis, can lead to serious complications like heart attacks.
Plaque buildup happens gradually over decades. The process begins with damage to the inner layers of the arteries, often caused by high cholesterol, high blood pressure, or smoking. The body attempts to repair this damage by depositing fatty substances, cholesterol, and other materials, forming plaque.
| Type | Description | Common Causes |
|---|---|---|
| Stable Angina | Chest pain or discomfort that occurs during physical exertion | Moderate plaque buildup |
| Unstable Angina | Chest pain that occurs unexpectedly, even at rest | Severe plaque buildup or blood clots |
| Myocardial Infarction (Heart Attack) | Complete blockage of blood flow to the heart | Ruptured plaque and blood clot formation |
Several factors increase the risk of developing heart blockages:
Symptoms vary depending on the severity of the blockage. Common signs include:
If you experience these symptoms, seek immediate medical attention. Early intervention can prevent severe damage.
Lifestyle changes can reduce the risk of heart blockages. The American Heart Association recommends:
For those with existing conditions like diabetes or high blood pressure, following your doctor's treatment plan is important.
Understanding what can cause a blockage in the heart empowers individuals to take proactive steps toward maintaining cardiovascular health. Regular check-ups and a healthy lifestyle are key to preventing heart blockages and their potentially life-threatening consequences.
