What should I know about heart attacks?
What is a heart attack?
A heart attack is the death of heart muscle due to the loss of blood supply. The loss of blood supply is usually caused by a complete blockage of a coronary artery, one of the arteries that supply blood to the heart muscle. Death of the heart muscle, in turn, causes chest pain and electrical instability of the heart muscle tissue.
What are the warning signs and symptoms of a heart attack?
Chest pain or pressure is the most common symptom of a heart attack; however, people who are having a heart attack may experience a variety of conditions that include jaw pain, sweating, heartburn, shortness of breath, jaw pain, toothache, headache, and nausea and vomiting.
What causes heart attacks?
Most of the deaths from heart attacks are caused by ventricular fibrillation of the heart that occurs before the victim of the heart attack can reach an emergency room. Those who reach the emergency room have an excellent prognosis; survival from a heart attack with modern treatment should exceed 90%. The 1% to 10% of heart attack victims who die later include those victims who suffer major damage to the heart muscle initially or who suffer additional damage later.
How many people have heart attacks each year?
Heart attack, or myocardial infarction, is the number one killer of both men and women in the U.S. Each year, about 735,000 Americans suffer a heart attack, and heart disease is the leading cause of death for both men and women in the US.
What exams, procedures, and imaging tests diagnose heart attacks?
Heart attacks are diagnosed with procedures such as coronary angiogram and PTCA (coronary balloon angioplasty), and clot-dissolving drugs are available that can quickly open blocked arteries in order to restore circulation to the heart and limit heart muscle damage. In order to optimally benefit heart attack victims and limit the extent of heart damage, these treatments to open blocked arteries should be given early during a heart attack. Blood pressure is not a reliable measurement of whether one is having a heart attack. Blood pressure during a heart attack can be low, normal, or elevated.
What are the treatments and therapies for heart attacks?
Heart attacks that are treated early can prevent or limit damage to the heart muscle. If you or someone you know is having a heart attack, call 911 immediately for an ambulance.
Drugs that treat heart attacks include, for example, aspirin, nitroglycerin, clot-busting drugs, percutaneous coronary intervention, medical procedures, cardiac rehabilitation, oxygen therapy, and lifestyle changes.
Cardiac arrest vs. heart attack
Sometimes there is confusion between the terms "cardiac arrest" and "heart attack." A heart attack, or myocardial infarction, is damage to the heart muscle that occurs due to reduced blood flow to the heart muscle, depriving the heart muscle of the oxygen it needs to function properly.
Cardiac arrest means that the heart stops beating and death is imminent. A heart attack, if severe, can lead to cardiac arrest, and this is what occurs when a heart attack is fatal. However, other conditions, such as serious arrhythmias or shock, can also cause cardiac arrest.
What does a heart attack feel like?
Knowing the early warning signs of heart attack is critical for prompt recognition and treatment. Many heart attacks start slowly, unlike the dramatic portrayal often seen in the movies. A person experiencing a heart attack may not even be sure of what is happening. Heart attack symptoms vary among individuals, and even a person who has had a previous heart attack may have different symptoms in a subsequent heart attack. Although chest pain or pressure is the most common symptom of a heart attack, heart attack victims may experience a diversity of symptoms. The following list describes the symptoms of a heart attack in more detail.
Heart attack warning signs and symptoms: chest, head, jaw, and tooth pain
Chest discomfort, manifest as pain, fullness, and/or squeezing sensation of the chest
Chest pain is the hallmark symptom of a heart attack, although it can take many different forms. In other cases, chest pain may not occur at all. The characteristic chest pain of a heart attack has been described as a sense of pressure, squeezing, fullness, or pain that starts in the center of the chest. The pain or discomfort typically lasts more than a few minutes, or it may go away and then return. It can spread down the arms, to the back, or to the head and neck. Both women and men report chest pain as a primary symptom of heart attack, but women more often than men are likely to have some of the other symptoms, such as nausea, jaw pain, or shortness of breath, that are described below.
Jaw pain, toothache, headache
The pain of a heart attack can spread down both arms, to the jaw or head, or to the back. Some people report tooth pain or headache as a symptom of a heart attack. It is possible to have these types of pain without chest pain during a heart attack.
Shortness of breath
Feeling short of breath or like you are gasping for air is a common symptom of a heart attack. Shortness of breath, or difficulty breathing, is medically known as dyspnea. Shortness of breath may occur before or during the chest pain of a heart attack, and in some cases, it may be associated with other heart attack symptoms without any chest pain.
Heart attack warning signs and symptoms: digestive problems
Nausea or feeling sick on your stomach is a less common but possible symptom of a heart attack. Sometimes belching or burping can accompany nausea, and some patients have described a feeling like indigestion associated with a heart attack. Women are more likely than men to report these less typical symptoms of heart attack, and some patients have described feeling as though they are developing the flu.
Nausea that accompanies a heart attack can become so severe that vomiting occurs.
General epigastric (upper middle abdomen) discomfort
Sometimes the pain of heart attack is described as stomach pain or pain in the middle of the upper abdomen. The pain usually feels more like the discomfort of heaviness rather than sharp, stabbing pain, and the pain tends to persist for more than a few minutes. This can occur with or without pain in the true chest area.
Heartburn and/or indigestion
As mentioned previously, some people experiencing a heart attack can have belching and burping and describe a feeling of indigestion. Likewise, the pain and pressure of a heart attack may occur in the epigastric or upper-middle abdominal area, similar to the pain of heartburn.
Other heart attack early warning signs and symptoms: arm and back pain
Arm pain (more commonly the left arm, but maybe either arm)
The chest pain of a heart attack can spread, or radiate, down one or both arms and to the shoulders. This often happens, and the pain may even extend to the wrist and fingers. This is most common on the left side of the body but it can also occur on the right side.
Upper back pain
The upper back is another common location for the spread of the pain from a heart attack. Most commonly, back pain that stems from a heart attack is described as occurring between the shoulder blades.
General malaise (vague feeling of illness)
A feeling of being generally unwell or like you are coming down with an illness can accompany a heart attack. This can be described as fatigue or even lightheadedness, with or without fainting. Some people will experience severe anxiety or panic during a heart attack. This has been described as feeling a sense of doom, as one experiences a panic attack.
What should you do if you think you are having a heart attack?
Doctors agree that if you're in doubt, get checked out anyway. Even if you're not sure if something is really wrong, you should call 911 if you experience heart attack symptoms. Prompt administration of drugs can help restore circulation to the heart and increase your chances of survival.
