| What are the symptoms of heart attack, cardiac arrest, and heart failure? How to distinguish? |
The three terms of heart attack, cardiac arrest, and heart failure have been repeated in everyday life and in popular science articles. I believe everyone is familiar.
So, do you know what the causes and symptoms of these three diseases are? What is the connection between them?
Today we will teach you how to distinguish between these three conditions:
Heart attack
In the case of a heart attack, it is often caused by blood clots or plaques accumulating in the arteries, causing blood flow to the heart to be blocked.
The heart muscle needs oxygen to survive, and when the blood flow is blocked, the muscle begins to die. Therefore, after a heart attack, the patient needs immediate surgery to resolve the blockage and restore blood flow.
A few hours, days, or even weeks before a heart attack, symptoms may have quietly appeared and lurked around. At this point the heart will continue to beat, but due to the blockage, it will not be able to get the oxygen-rich blood it needs.
Everyone's symptoms may be different during a heart attack. About two-thirds of people experience chest pain, shortness of breath, or days or even weeks before a heart attack.
In the event of a heart attack, the pain may start in the center of the chest and then spread to the back, chin or arm. Or the back, chin, and arms can feel pain, but the chest doesn't feel it. Sometimes, patients also feel stomach pain, and mistaken heart attack as indigestion.
Other symptoms include dizziness, sudden sweating, nausea, shortness of breath, increased heart, abnormal heart rhythm, loss of consciousness, restlessness, anxiety, and blueness of lips, hands, and feet.
If you have any of the above symptoms, you need to call the emergency number immediately.
Cardiac arrest
When a cardiac arrest occurs, the heart stops beating and needs to be restarted.
A heart attack is a blood circulation problem, and cardiac arrest is an electrocardiogram problem caused by a heart rate disorder. Most heart attacks do not cause cardiac arrest. However, heart attack is a common cause of cardiac arrest.
In many cases, cardiac arrest is a temporary condition experienced during first aid, and no heart disease can occur, but many patients may have early warning symptoms as early as one month before cardiac arrest.
Because the cardiac arrest stops the heartbeat, the brain, lungs, and other organs cannot get the blood and oxygen they need. If left untreated, cardiac arrest can cause death within a few minutes. If CPR cardiopulmonary resuscitation is performed on the patient immediately, it is possible that the rescue is successful.
Symptoms of cardiac arrest include dizziness, loss of consciousness, and shortness of breath. Within a few seconds of a cardiac arrest, the patient becomes slow to respond and has difficulty breathing.
If you see someone has a cardiac arrest, call the emergency number immediately.
In addition, the use of an automated external defibrillator (AED) with CPR can achieve a 23% higher survival rate than CPR alone. Because CPR is to pump blood to the heart, it circulates blood to the organs. The AED will shock the heart and restore the heart rhythm.
Heart failure
Heart failure occurs when the heart muscle fails to pump enough blood into the body. Heart failure is usually a long-term chronic disease, but it can also be an acute attack.
In patients with heart failure, the heart pumps abnormal blood, and its hormones and nervous system respond to a decrease in blood volume - which may lead to an increase in blood pressure, an increase in heart rate, and accumulation of salt and water in the heart. If the fluid is increased, congestive heart failure will occur.
There may be no symptoms in the early stages of congestive heart failure. As the disease progresses, weight gain, nausea, and other symptoms that are usually not related to the heart may occur.
Include:
Dry cough, especially when lying down
Older people are confused, lethargic, and lose their sense of direction
Dizziness, coma, fatigue or weakness
Edema, usually in the legs, ankles and feet
Nocturnal urine
Nausea, swollen abdomen, tenderness or pain caused by body edema, liver congestion
Breathing faster
Blue skin
Feeling anxious, upset, breathing difficulties
Shortness of breath and pulmonary congestion
Asthma, respiratory tract, similar to asthma
Heart failure is usually caused by other diseases, the most common cause being coronary artery disease. Other causes include different types of heart disease, lung thrombosis, thyroid problems, heart valve disease, kidney failure, and poor management of hypertension.
Heart failure can occur in people of any age, especially when suffering from congenital heart defects. Among them, the elderly have weakened heart function due to age, and are more susceptible to heart failure.
Heart failure can also cause arrhythmias, leading to cardiac arrest.
