what is the symptoms of m.i?

Answer 1

Acute myocardial infarction (AMI or MI), commonly known as a heart attack, is a disease state that occurs when the blood supply to a part of the heart is interrupted. The resulting ischemia or oxygen shortage causes damage and potential death of heart tissue. It is a medical emergency, and the leading cause of death for both men and women all over the world.[1] Important risk factors are a previous history of vascular disease such as atherosclerotic coronary heart disease and/or angina, a previous heart attack or stroke, any previous episodes of abnormal heart rhythms or syncope, older age—especially men over 40 and women over 50, smoking, excessive alcohol consumption, the abuse of certain illicit drugs, high triglyceride levels, high LDL ("Low-density lipoprotein") and low HDL ("High density lipoprotein"), diabetes, high blood pressure, obesity, and chronically high levels of stress in certain persons.

The term myocardial infarction is derived from myocardium (the heart muscle) and infarction (tissue death due to oxygen starvation). The phrase "heart attack" is sometimes used incorrectly to describe sudden cardiac death, which may or may not be the result of acute myocardial infarction.
Classical symptoms of acute myocardial infarction include chest pain, shortness of breath, nausea, vomiting, palpitations, sweating, and anxiety or a feeling of impending doom. Patients frequently feel suddenly ill. Women often experience different symptoms than men. The most common symptoms of MI in women include shortness of breath, weakness, and fatigue. Approximately one third of all myocardial infarctions are silent, without chest pain or other symptoms.Immediate treatment for suspected acute myocardial infarction includes oxygen, aspirin, glyceryl trinitrate and pain relief. The patient will receive a number of diagnostic tests, such as an electrocardiogram (ECG, EKG), a chest X-ray and blood tests to detect elevated creatine kinase or troponin levels (these are chemical markers released by damaged tissues, especially the myocardium). Further treatment may include either medications to break down blood clots that block the blood flow to the heart, or mechanically restoring the flow by dilatation or bypass surgery of the blocked coronary artery. Coronary care unit admission allows rapid and safe treatment of complications such as abnormal heart rhythms.

Unfortunately, these symptoms aren't unique to pregnancy. Some can indicate that you're getting sick or that your period is about to start. Likewise, you can be pregnant without experiencing any of these symptoms. Other pregnancy signs include: 1. Implantation Bleeding 2. Delay/Difference in Menstruation 3. Swollen/Tender Breasts 4. Fatigue/Tiredness 5. Nausea/Morning Sickness 6. Backaches 7. Headaches 8. Frequent Urination 9. Darkening of Areolas 10. Food Cravings However if you want a confirmed answer on whether you are pregnant or not, what you can do is to take a home pregnancy test one week later after your missed period. Another alternative is to see a doctor and have a blood test taken.

Heart Attack Symptoms & Signs

Chest pain behind the sternum (breastbone) is a major symptom of heart attack, but in many cases the pain may be subtle or even completely absent (called a "silent heart attack"), especially in the elderly and diabetics. Often, the pain radiates from your chest to your arms or shoulder; neck, teeth, or jaw; abdomen or back. Sometimes, the pain is only felt in one these other locations.

The pain typically lasts longer than 20 minutes and is generally not fully relieved by rest or nitrioglycerine, both of which can clear pain from angina.

The pain can be intense and severe or quite subtle and confusing. It can feel like:

*
squeezing or heavy pressure
*
a tight band on the chest
*
"an elephant sitting on [your] chest"
*
bad indigestion

Other symptoms you may have either alone or along with chest pain include:

* Shortness of breath
* Cough
* Lightheadedness - dizziness
* Fainting
* Nausea or vomiting
* Sweating, which may be profuse
* Feeling of "impending doom"
* Anxiety

Chest pain is discomfort or pain that you feel anywhere along the front of your body between your neck and upper abdomen.

Overview & Considerations

Like many people with chest pain, you may fear a heart attack. However, there are many possible causes of chest pain. Some causes are mildly inconvenient, while other causes are serious, even life-threatening. Any organ or tissue in your chest can be the source of pain, including your heart, lungs, esophagus, muscles, ribs, tendons, or nerves.

If your chest pain is new or different from previous episodes of chest pain, you should be evaluated by a healthcare provider right away. This is especially true if you have any symptoms suggestive of a heart attack.

Symptoms of a heart attack -- call emergency or 911

* You would describe your pain as a pressure, squeezing or tightness in the chest.
* Your pain radiates to your jaw, left arm, or between your shoulder blades in your back
* You have any sweating, nausea, dizziness, palpitations (a feeling of a racing heart), or shortness of breath.

Take these symptoms even more seriously if you have risk factors for heart disease like family history, cigarette smoking, high cholesterol, high blood pressure, diabetes, or cocaine use.

Angina
Angina is another type of heart-related chest pain. This pain occurs because your heart is not getting enough blood and oxygen. Angina pain can be similar to the pain of a heart attack. Angina is called stable angina when your chest pain begins at a predictable level of activity. (For example, when you walk up a steep hill.) However, if your chest pain happens unexpectedly after light activity or it occurs at rest, this is called unstable angina. This is a more dangerous form of angina and you need to be seen in an emergency room right away.
Indigestion is a vague feeling of abdominal discomfort -- possibly including a feeling of fullness, belching, bloating, and nausea.
Stress can come from any situation or thought that makes you feel frustrated, angry, or anxious. What is stressful to one person is not necessarily stressful to another.

Anxiety is a feeling of apprehension or fear. The source of this uneasiness is not always known or recognized, which can add to the distress you feel.
