A heart attack, which is the most common consequence of a heart disease, can be recognized not only by three symptoms in the previous article mentioned, but also be recognized by other warning signs, such as unusual chest, stomach or abdominal pain, nausea or dizziness, cold sweat or paleness, shortness of breath or difficulty breathing, weakness or fatigue, palpitations, and unexplained anxiety.

It is very important to be calm when a relative, friend or person has a heart attack, since you will have to know what to do if something like this happens. The first thing is to call an ambulance immediately. Then, according to experts, check whether the patient is conscious or not and place them flat on their back, kneel beside them and put one hand on their forehead and the other on their chin.

After doing these, tilt back their head. And lift their chin until their teeth almost touch. You will have to look and listen for signs of breathing. Pinch their nose and cover their mouth with yours, if the person is not breathing normally. Give two full breaths. The person's chest should rise as a consequence.

You may check the person's pulse by putting your fingers on their neck, next to their Adam's apple and windpipe, which is the tube through which air passes from mouth to lungs. Put your hands on the centre of the person's chest at the height of their nipples, if there is no pulse. Then put one hand on top of the other. Push down two inches on their chest 15 times. Continue with the two breaths and 15 pumps until an ambulance arrives.
