Difference Between Signs Of Cardiac Arrest and Symptom Of Heart Attack
Symptoms are irregularities that a person starts to experience or feel and signifies the start of a disease. Signs are sensed and spotted by medical professionals who observe the remedial characteristics. When a doctor is able to spot a symptom, it becomes a sign. The difference between the two can be cleared by an example. When you presume you have fever and complain it to the doctor, it is a symptom. But when the doctor checks your body temperature and finds out it is abnormal, then it is a sign.
The most deadly medical crisis faced by a person is heart attack. In such a case the patient needs urgent treatment and therefore it is necessary to recognize its symptoms. If there is an inadequate supply of blood to the heart then chances of a heart attack or Myocardial infarction increase. The reason for this blockage is due to clot formation or cholesterol plugs that are embedded in the blood vessels. There is terrible chest pain at either the middle of the chest, left side of the chest, left arm, shoulder or at the back. Surprisingly it could just exist as a tooth ache! The pain experienced by the person is its form the most ruthless and excruciating of all. Morphine is a pain killer that helps in lessening the pain caused. When the sympathetic nerve is stimulated excessively, it results in a heart attack. Sweating, nausea, light headedness is also observed.
The heart muscles are damaged extensively due to a heart attack and it also affects its pumping ability. The lungs get accumulated by the fluid and the oxygen supply to the tissues is reduced. The patient comes across DYSPNEA, that is, the patient feels difficulty while breathing. If the patient has gone through a heart transplant or is diabetic, then symptoms such as sweating and pain are not experienced due to improper functioning of the nerves. This is known as silent myocardial infarction.
The inability of the heart to pump sufficient amount of blood results in heart failure. Crack sounds are made by the lower lungs which can be detected by a doctor with the help of a stethoscope. The sounds are made due to the leaking of fluid which causes pulmonary edema. The rate of respiration increase as a result and there is difficulty in breathing. The parts of the body that are under the effect of gravity tend to swell up if the heart failure is sustained for a long time. For example, the ankle would swell if the person is seated or is standing and the back would swell if he or she was lying on the bed.
When in the case of heart failure there is low supply of oxygen to the tissues, then the de-oxygenated blood becomes blue in color. This is known as cyanosis. The tongue also becomes blue in color.
