As per research, about 800,000 people in the country suffer from a heart attack yearly. Given the severity of this cardiovascular disease, it is important for everyone to have basic knowledge of its early signs and symptoms. Like for any ailment, the human body shows early warning signs of heart attack too, and if recognized in time, it can help save one’s life. Here are some early signs of a heart attack one shouldn’t ignore. Pain in the upper body One of the earliest signs of a heart attack is experiencing discomfort or throbbing pain in the arms, neck, back, or jaw. Sometimes, this discomfort may even be felt in the upper part of the abdomen. Breathlessness and tightness in the chest If one suddenly experiences heavy breathing or breathlessness as if they have just run a marathon (when they have not), it might be a serious sign of a heart attack. Sometimes, the shortness of breath may also be felt along with a tightness in the chest. In such a scenario, one may need immediate medical attention. Indigestion Sometimes, the early signs of a heart attack can also include indigestion, nausea, and vomiting. These may not necessarily indicate a heart attack but they should not be dismissed.
