What Causes a Heart Attack and How Can You Prevent One?
Published: Jan 03, 2024
Knowing what causes heart attacks can help in preventing them. Let's explore the common and lesser-known causes.
Common Causes
The most common cause of a heart attack is coronary artery disease, where plaque buildup narrows the arteries and reduces blood flow to the heart. Plaque can rupture, forming a blood clot that blocks the flow completely. This blockage can lead to a heart attack if not treated promptly.
Other Contributing Factors
Stress, smoking, high blood pressure, and high cholesterol are significant risk factors contributing to heart attacks. These factors can damage arteries, making them vulnerable to blockages. A healthy lifestyle is crucial in reducing these risks.
Type 2 Heart Attack Causes
Type 2 heart attacks are caused by an imbalance between oxygen supply and demand in the heart, often without a blockage. Conditions like severe anemia, arrhythmias, or sepsis can lead to this type of heart attack. It's less common but still a serious medical condition.
