5. Increased anxiety
See your physician if you experienced increased levels of anxiety that do not have a ready explanation.
6. Weak or heavy arms
When your heart does not receive sufficient oxygen to function, it can send impulses to your spine. When this happens, the nerves that are interconnected between your heart, spine, and arms send impulses that cause pain in your arms. If you experience numbness in your arm, you may be having a heart attack.
Keeping watch for these early warning signs of a heart attack could save your life. Share this information with your loved ones to protect their heart, too!
