30 Important Signs That May Indicate A Heart Attack

Difficulty in Breathing

This is a serious sign that you may have trouble breathing when you’re not actively trying to breathe. When you are at rest, your muscles relax and your breathing should be easy. You should see a doctor immediately if you experience breathing difficulties while you are sleeping, lying down, or doing light activities. The American Heart Association states that heart disease can occur when blood is unable to flow through the veins. This can lead to fluid buildup in the lungs, which can cause heart problems.
