Question: what is myocardial infarction?
Acute myocardial infarction, also known as a heart attack, is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage.
This is usually the result of a blockage in one or more of the coronary arteries. A blockage can develop due to a buildup of plaque, a substance mostly made of fat, cholesterol, and cellular waste products or due to a sudden blood clot that forms on the blockage.
Call 911 or local emergency services right away if you think that you or someone you know may be having a heart attack.
Question: What are the usual symptoms of myocardial infarction?
In an emergency
If you, or someone around you, experiences symptoms of a heart attack, call 911 or go to the nearest emergency department.

While the classic symptoms of a heart attack are chest pain and shortness of breath, the symptoms can be quite varied. The most common symptoms of a heart attack include
:
pressure or tightness in the chest
pain in the chest, back, jaw, and other areas of the upper body that lasts more than a few minutes or that goes away and comes back
shortness of breath
sweating
nausea
vomiting
anxiety
feeling like you're going to faint
a fast heart rate
sense of impending doom
It's important to note that not all people who have heart attacks experience the same symptoms or the same severity of symptoms.
Chest pain is the most commonly reported symptom among both women and men. However, women are a bit more likely
than men to have more of the 'atypical' symptoms, such as:
shortness of breath
jaw pain
upper back pain
lightheadedness
nausea
vomiting
In fact, some women who have had a heart attack report that their symptoms felt like the symptoms of the flu.
Question: causes of myocardial infarction?
Your heart is the main organ in your cardiovascular system, which also includes different types of blood vessels. Some of the most important vessels are the arteries. They take oxygen-rich blood to your body and all of your organs.
The coronary arteries take oxygen-rich blood specifically to your heart muscle. When these arteries become blocked or narrowed due to a buildup of plaque, the blood flow to your heart can decrease significantly or stop completely. This can cause a heart attack.
Question: What are the potential risk factors associated with myocardial infarction?
A major trigger for heart problems can be
the fat content of food. People who eat a lot of processed and fried foods, as well as some meat and dairy foods that contain unhealthy saturated and trans saturated fats, are at a higher risk for heart disease. Obesity can increase this risk.
According to one study, replacing 2 percent
of calories consumed from carbs with trans fat could double the risk of heart disease.
In addition, your blood also contains fat known as triglycerides, which store
excess energy from the food that you eat. When the level of triglycerides in your blood is high, you may be more at risk for cardiovascular disease.
If, along with that, you also have a high level of low-density lipoprotein (LDL) in your blood, your risk may be even higher. This is because LDL cholesterol can stick to the walls of your arteries and produce plaque, a hard substance that blocks
blood flow in the arteries.
Reducing your cholesterol and the unhealthy fat in your body typically requires eating a balanced diet that contains few processed foods, and when necessary, taking medications called statins.
Your doctor would be able to recommend the best nutrition plan for you and determine whether you need to take medications.
Additional risks
In addition to your diet, the following factors can also increase your risk of heart problems
:
High blood pressure. This can damage your arteries and accelerate the buildup of plaque.
High blood sugar levels. Having high levels of blood sugar can damage blood vessels and eventually lead to coronary artery disease.
Smoking. Smoking may increase your risk for heart attack and lead to other cardiovascular conditions and diseases.
Age. The risk of having a heart attack increases with age. Men are at a higher risk of a heart attack after age 45, and women are at a higher risk of a heart attack after age 55.
Sex. Not only do men have a significantly higher risk of having a heart attack than women, but they also often have heart attacks earlier in life.
Family history. You're more likely to have a heart attack if you have a family history of early heart disease. Your risk is especially high if you have male family members who developed heart disease before age 55 or if you have female family members who developed heart disease before age 65.
Stress. Although the evidence for this is still limited, stress may also
be a trigger for acute myocardial infarction. Reducing chronic anxiety or stress can help reduce the risk of a heart attack and other heart problems over time.
Physical inactivity. Getting regular exercise can help keep your heart healthy by helping you maintain a moderate weight, as well as reduce your blood pressure, cholesterol, and blood sugar levels.
Drug use. The use of certain drugs, including cocaine and amphetamines, can narrow the blood vessels, which could increase the risk of heart attack.
Preeclampsia. If you have a history of preeclampsia, or high blood pressure during pregnancy, you may be at a higher risk of developing heart problems later in life.
Question: How do doctors usually figure out if someone has myocardial infarction, diagnosis?
To determine whether you've had a heart attack, your doctor will look over the history of your symptoms, as well as your vital signs such as your blood pressure. Your doctor will then complete a physical exam with specific attention to the heart.
Your doctor will also run a number of different tests if they suspect that you've had a heart attack. An electrocardiogram (EKG) may be done to measure your heart's electrical activity.
Blood tests will also be used to check for proteins that are associated with heart damage, such as troponin.
Your doctor may also perform an angiogram with coronary catheterization to look for areas of blockage in your arteries.
Question: What are the ways to prevent myocardial infarction?
There are many steps you can take to prevent a heart attack, even if you've had one before.
One way to lower your risk is to eat a heart-healthy diet.
This diet should largely consist of:
whole grains
vegetables
fruits
lean protein
You should also try to reduce the following in your diet:
sugar
processed foods
This is especially important for people with diabetes, high blood pressure, and high cholesterol.
Exercising several times a week will also improve your cardiovascular health. If you've had a heart attack recently, you should speak with your doctor before starting a new exercise plan.
It's also important to stop smoking if you smoke. Quitting smoking will significantly lower your risk of a heart attack and improve both your heart and lung health. You should also avoid being around secondhand smoke.
