Myocardial Infarction Symptoms: How to Know if You’re at Risk

Some people will experience myocardial infarction symptoms before they have a heart attack. While others won’t show any warning signs at all until it’s too late. So how can you tell if you’re at risk? Read on to learn more about the early signs of myocardial infarction symptoms. How to prevent them before they become full-blown attacks.

Myocardial Infarction-What is a heart attack?

A heart attack is also called a myocardial infarction (MI). It occurs when blood flow to an area of your heart muscle is suddenly blocked. This blockage interrupts oxygen flow and deprives that part of your heart muscle of oxygen and other nutrients it needs. Within minutes, brain cells in that area begin to die due to a lack of oxygen and nutrients. If you don’t get help within an hour, permanent damage can occur in that part of your heart muscle.

 By knowing what a heart attack is and having a basic understanding of how it happens. You can help prevent one. Myocardial infarction symptoms include chest pain or discomfort, which can also be felt in your left arm, neck, or jaw. Other common signs of a heart attack include shortness of breath, sweating, and nausea. These symptoms may not always be present in every heart attack. They’re important for knowing what to look out for if you are at risk. Heart attacks usually occur when there’s some type of blockage in your coronary arteries (also called coronary artery disease). That blockage restricts blood flow and oxygen supply and causes damage over time.

What are the signs and Myocardial Infarction symptoms of a heart attack?

The classic signs and symptoms of a heart attack—are pain or discomfort in your chest. Radiating down your left arm and possibly into your jaw—are seen in only about 20 percent of all heart attacks. If you think you’re having a heart attack, call 911 immediately. There is no time to waste, even if you have one of these classic symptoms!

 Although many people think of a heart attack as something that happens suddenly and painfully. Most heart attacks don’t happen that way. About 75 percent of people who have a heart attack first feel symptoms over two days before their actual heart attack—as little as 15 minutes or up to 48 hours in advance. And while you may think that chest pain is one of these symptoms, it isn’t always present during a heart attack. Another common symptom is shortness of breath with or without chest discomfort, although again, not everyone experiences these symptoms in a heart attack. So what are some other possible signs and symptoms? If you notice any new or different sensations below your breastbone—or around your shoulders, neck, or jawline—get them checked out by your doctor right away.

Who is more likely to have a heart attack?

Anyone can have a heart attack, but there are some who are more likely than others. If you are at risk of a heart attack, take steps now to reduce your risk and improve your cardiovascular health. Here is how to know you may be at risk.

 More than 10 million people experience a heart attack every year. Men are more likely than women to have one, and older individuals are more likely than younger ones. Other risk factors include having pre-existing medical conditions such as diabetes, obesity, high blood pressure, or a family history of heart disease. If you smoke cigarettes or use recreational drugs, have been diagnosed with depression, or have high cholesterol levels, these are also indicators that you may be at higher risk for a heart attack.


If you think you’re at risk of a heart attack and your symptoms match those listed below, it’s important that you get immediate medical attention from your doctor and call emergency services as well.

What causes an MI?

The most common cause of an MI is atherosclerosis, a buildup of plaque inside your arteries that restricts blood flow and puts you at risk for heart attack or stroke. Plaque forms when fat, cholesterol, calcium, and other substances build up on your artery walls. If a blood clot forms in one of these narrowings due to plaque, it can lead to an MI.

 Another common cause of an MI is coronary artery disease (CAD), which refers to a buildup of plaque in the arteries that supply blood to your heart. Plaque typically forms on the walls of these arteries, and narrowed or blocked arteries may prevent blood from reaching your heart, leading to an MI.

Atherosclerosis and CAD can also increase your risk for conditions such as peripheral artery disease (PAD) and carotid artery disease (CAD). PAD is another type of heart disease that develops when plaque builds up in one or more major leg arteries, while CAD narrows or blocks blood flow through carotid arteries in your neck.

How do I know when it’s time to see a doctor?

Pay attention to your body. If you feel chest pain or discomfort that lasts longer than a few minutes, make an appointment with your doctor. The symptoms of myocardial infarction can differ between men and women, as well as among individuals, so it’s important to keep an eye out for yours. As soon as you notice symptoms of myocardial infarction, get medical help immediately.

 The signs of myocardial infarction vary from person to person. In general, they can include pain in your chest, which may be mild or severe; pain in other areas of your body, such as your back, neck, or arm; a sudden sense of feeling lightheaded or weak; and symptoms similar to those you’d experience with indigestion. If you experience these symptoms, it’s time to call emergency services right away. Myocardial infarction symptoms can also resemble those associated with a panic attack.

Where can I find more information about cardiac care?-Myocardial Infarction

The American Heart Association is a good place to start. It offers up-to-date information on cardiac care and living with heart disease. Plus there are links to resources on everything from secondhand smoke to CPR training. You can also search for about your condition by simply Googling myocardial infarction symptoms or myocardial infarction in quotes (without either quote). Another good site, WebMD’s Heart Center, covers all of these topics in depth.

 Another great source is your primary care physician. Many family doctors offer blood pressure checks and other tests that can help determine whether you’re a candidate for medications. Surgery, or invasive procedures. If you’re unsure about which doctor to choose. Contact your insurance provider for recommendations or look online for reviews of physicians in your area. It’s always important to feel comfortable with whomever you decide on. To schedule an appointment and chatting over coffee before you start seeing them regularly can give you a good idea of how things will go once they become your primary care physician.
