Unstable Angina Causes and Risk Factors
Unstable angina occurs when the blood flow to the heart is blocked, causing the heart muscle to become damaged. There are several factors that can contribute to the development of unstable angina.
Blockages in the Coronary Arteries
The most common cause of unstable angina is the buildup of plaque in the coronary arteries, which supply blood to the heart. This buildup can lead to blockages, reducing blood flow to the heart and causing chest pain.
Risk Factors
Certain risk factors can increase your likelihood of developing unstable angina. These include:
- High blood pressure: Uncontrolled high blood pressure can damage the coronary arteries, leading to blockages.
- High cholesterol: High levels of low-density lipoprotein (LDL) cholesterol can contribute to the buildup of plaque in the coronary arteries.
- Smoking: Smoking damages the coronary arteries and increases the risk of heart disease.
- Diabetes: Having diabetes increases the risk of heart disease and unstable angina.
- Obesity: Being overweight or obese can increase the risk of heart disease and unstable angina.
- Family history: Having a family history of heart disease can increase your risk of developing unstable angina.
