These 8 signs will warn you a month before a heart attack

Feeling tired or worn out after a stressful day or restless night is typical, but this is another common sign of a heart attack. You may feel like you're more tired than usual, or like you cannot seem to get enough rest. This may be due to a decrease in blood flow to your heart, which causes the heart to work harder to pump blood throughout the body. Approximately 70% of women experience fatigue before a heart attack.
