When a coronary artery becomes blocked (usually by a blood clot), an area of heart tissue loses its blood supply. This reduction of blood can quickly damage and/or kill heart tissue, so quick treatments in an emergency department and/or catheterisation suite are necessary to reduce the loss of heart tissue. Experts have mentioned some few methods Coronary Pulmonary Resuscitation (CPR) .
Coronary artery disease (CAD) occurs when plaque, a sticky substance, narrows or partially obstructs coronary arteries (like sticky material stopping up a straw) and can result in reduced blood flow.
This reduced blood flow may cause chest pain (angina), a warning sign of potential heart problems such as a heart attack. Plaque may also trap small blood clots, completely blocking a coronary artery suddenly, resulting in a heart attack.
Plaque can occur in coronary and other arteries (for example, carotid arteries). Some plaque may be hard or firm on the outside, but soft and mushy or sticky on the inside. If the hard shell-like area cracks open, blood components like platelets and small blood clots form a large clot and effectively block blood flow through the artery. The heart tissue downstream from the clot then suffers from lack of blood and becomes damaged or dies.
A heart attack can cause other abnormalities besides blocking blood flow. For example, sudden cardiac death may occur when the heart’s electrical signals become erratic (arrhythmias). When the heart tissue that is responsible for regular electrical stimulus of heart muscle contractions is damaged, the heart stops effectively pumping blood.
Death usually occurs in a few minutes after the heart stops pumping blood. Consequently, rapid coronary pulmonary resuscitation (CPR) and a restoration of the organized electrical activity (usually done by electric shock with a defibrillator) may restore effective pumping of blood. This can be lifesaving for some individuals
Loss of heart tissue due to a blockage can cause symptoms such as chest pain, shortness of breath, weakness, and even death. Wellness &Fitness talked about some quick treatments we can use to reduced the number of deaths from heart attacks He said “Let us say it is 7.25pm and you are going home (alone of course) after an unusually hard day on the job.
“You are really tired, upset and frustrated. Suddenly you start experiencing severe pain in your chest that starts to drag out into your arm and up in to your jaw. You are only about five km from the hospital nearest your home.
“Unfortunately you don’t know if you’ll be able to make it that far. You have been trained in CPR, but the guy who taught the course did not tell you how to perform it on yourself.
“Since many people are alone when they suffer a heart attack without help, the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness.
“However, these victims can help themselves by coughing repeatedly and very vigorously. A deep breath should be taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest. A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again.
“Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating. The squeezing pressure on the heart also helps it regain normal rhythm. In this way, heart attack victims can get to a hospital.
“While heart disease is treatable by many methods, prevention or healing by living a reasonable lifestyle seems to be one of the best ways to reduce this widespread health problem.
