Nowadays, most people lead busy lives and are forced to follow hectic schedules. This can easily cause stress, which later leads to more serious health issues. The food most Americans consume, fast food, is also a factor which negatively affects the quality of life. A great number of Americans struggle to maintain healthy weight and obesity is an issue many face.

One of the consequences of the above mentioned is a heart failure, or heart attack. In fact, heart attack is number one cause of death in America.

According to some research, the body knows if a heart attack is about to take place and is trying to warn us.

Some of the symptoms we should pay attention to and try to treat as fast as possible are the following:

1. Fatigue
Being extremely tired, sleepy, exhausted or lacking energy to perform even the slightest of tasks can be a sign of fatigue. One of the reasons it may affect a person are the lowered levels of blood that go to the heart. This usually takes place when arteries get narrowed. Fatigue can easily happen if someone experiences heart issues.
