A heart attack occurs when a coronary artery supplying the heart with blood and oxygen becomes blocked or obstructed. This restricts the flow of blood and oxygen to the heart muscles. Some heart attacks are instant and can be fatal, while others are smaller events that serve as warning signs to make necessary changes in the lifestyle and diet.
Typical signs of a heart attack involve:
Heaviness in chest
Nausea or cold sweats
Paleness in the face
Pain in the upper body, particularly in one or both arms, the neck, back, jaw or stomach
While pain in the chest or arm is a common sign of heart attack, it is not always experienced. Women are more unlikely to experience chest pain and may show other signs like fatigue or upper body discomfort.
People suffering from the problem of diabetes, high cholesterol, chronic stress and high blood pressure are more prone to get a heart attack. Besides, smoking, poor lifestyle habits and lack of physical activity also increases the risk.
