Rolling Stone magazine was in trouble Monday after releasing prematurely the news about Tom Petty’s Heart sudden death. Others claimed it was due to a heart attack, but others suggested that it was a cardiac arrest. Unfortunately, Petty died from cardiac arrest. However, it is important to remember that neither a heart attack nor a cardiac arrest are synonymous with death.
Although it is rare, cardiac arrest sufferers can be revive. A heart attack is associate a low risk of death within 18 months of treatment in Australia. Both of these are heart diseases, and heart failure can occur in either. What are the differences between heart attack, cardiac arrest and heart failure?
It is easiest to see the heart as a building, and to approach it like a tradesman to help you understand its conditions. Because it is essentially an electrical problem, cardiac arrest is the domain of the sparkie. The flow of electricity from the pacemaker cells at the top (sinoatrial) causes the heart to beat in a controlled and synchronised fashion.
Because the wiring runs throughout the heart, the electrical signal is transmit and receive by the heart muscle cells. It then powers the cells and beats as it moves through the circuit. There are mains electrical circuits that control the flow of energy, and can use as backups if any part of the circuit is damage. These include the atrioventricular, bundle of His, and purkinje fibres. All three can cause the heartbeat to occur, but at a slower pace than the sinoatrial.
This is not always what you expect. Circuit disruptions can be cause by diseases such as blockages, genetic conditions, and age-relate degeneration.
Two things could result. The first is an electrical blackout, in which there is no electricity. This is call asystole. The second is an electrical surge from the heart muscle that disrupts and stops the heart pumping. These surges are often referred to as asystole. These are the main types of cardiac arrest.
These conditions will stop your heart from pumping. The person will lose consciousness because blood cannot travel to the brain.
The defibrillator paddles deliver electric shocks to the patients in dramatic scenes. This is effective for treating ventricular arrhythmias because it can re-organise electricity surges. However, it is not efficient for asystole (where there’s no electricity).
Good-quality CPR is essential in this situation. They will die if they are left without blood supply to the brain or the rest of their body for too long. The survival rate from cardiac arrest in Australia occurs outside of hospitals. This drops to 24% one year later.
This is the area where the plumber lives. Although a heart attack can be used to refer to a variety of heart conditions, it is actually an acute myocardial injury, or AMI.
Although the heart supplies blood to all parts of the body, it is also dependent on its own blood supply. It does not receive it from the blood flowing through its chambers. The heart receives blood from the veins and arteries that are located on the outside of it. This supplies oxygen and carbon dioxide to the body.
Our Western lifestyle and diet have led to high levels of disease in these arteries. This is called “atherosclerosis”. This can cause arteries to narrow, and lead to sudden blockages that can result in heart attacks.
AMIs are usually caused by sudden ruptures of atherosclerotic plaque containing cholesterol, fat cells, and immune cells. This can cause a blood clot to form and block the flow of blood.
The heart muscle tissue, which is normally supply by these arteries, stops receiving blood and oxygen within minutes. This causes intense pain. This whole section of the hearts wall could die within 90 minutes and it may stop beating. This decreases the overall performance and puts the hearts at risk for ventricular arrhythmias, which is the dangerous surge of electricity.
Modern medicine has made it possible to survive hearts attacks significantly easier. One-third of hearts attacks were fatal in 1960. After having one in Australia in 2012, this number rose to 16%.
Despite the high survival rate for heart attacks, the burden of disease remains heavy. Hearts attacks account for 12% of deaths in Australia. One Australian is kill by a heart attack every 27 minutes.
Hearts failure is a structural problem, so it’s the problem of the carpenter. The hearts is unable to supply blood properly, so tissues aren’t receiving oxygen and other nutrients. Blood pools in the legs and abdomen. The hearts failure can be caused by a weakening in the pump or stiffening the hearts, which causes it to lose elasticity and stop filling with blood.
It can be cause by a variety of conditions including hearts attacks, genetic disorders, infections, and high blood pressure. Hearts failure is more common than the two previous. Failure is characterize by a progressive worsening in shortness of breath, fatigue and swelling that can have a significant impact upon quality of life.
Hearts failure can lead to death. This is because of the disruption in the construction of the house, which causes electricity problems. Organ failure also occurs due to a lack of oxygen supply.
All three conditions can be avoid and treat by living a healthy lifestyle and seeing your doctor. You can also take medications to lower your risk of developing hearts disease.
