Myocardial infarction:

A heart attack or myocardial infraction happens when the progression of blood to the heart is obstructed. The blockage is regularly a development of fat, cholesterol and different substances, which structure a plaque in the arteries that feed the heart (coronary arteries).

A plaque can burst and shape a coagulation that squares blood stream. The intruded-on blood stream can harm or demolish some portion of the heart muscle.

A heart attack, likewise, called a myocardial dead tissue, can be lethal, however treatment has improved drastically throughout the long term. It's pivotal to call 911 or crisis clinical assistance on the off chance that you figure you may be having a heart attack.

Symptoms of Myocardial Infraction

Regular heart attack signs and manifestations include:

• Pressing factor, snugness, torment, or a crushing or throbbing sensation in your chest or arms that may spread to your neck, jaw or back
• Sickness, acid reflux, heartburn or stomach torment
• Windedness
• Cold perspiration
• Weariness
• Dazedness or abrupt wooziness
• Heart attack side effects shift

Not all individuals who have heart attacks have similar manifestations or have similar seriousness of side effects. A few people have mellow torment; others have more extreme agony. A few people have no indications. For other people, the principal sign might be abrupt heart failure. Notwithstanding, the more signs and manifestations you have, the more prominent the possibility you're having a heart attack.

When Should You See A Specialist?

Act right away. A few people stand by too long on the grounds that they don't perceive the significant signs and side effects. Make these strides:

Call for an emergency clinical assistance. Quickly call your neighborhood crisis number or a nearby hospital. In the event that you don't approach crisis clinical administrations, have somebody drive you to the closest clinic.

Drive yourself just if there are no different alternatives. Since your condition can deteriorate, driving yourself puts you and others in danger.

Take dynamite, whenever endorsed to you by a specialist. Accept it as trained while anticipating crisis help.

Take headache medicine, whenever suggested. Taking prescribed medicine during a heart attack could lessen heart harm by assisting with shielding your blood from thickening.

Myocardial infarction: 

A myocardial infarction (commonly called a heart attack) is an extremely dangerous condition that happens because of a lack of blood flow to your heart muscle. The lack of blood flow can occur because of many different factors but is usually related to a blockage in one or more of your heart’s arteries. Without blood flow, the affected heart muscle will begin to die. If blood flow isn’t restored quickly, a heart attack can cause permanent heart damage and death.

Causes 

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.

Symptoms 

The following are the most common symptoms of a heart attack. But each person may have slightly different symptoms.

• Severe pressure, fullness, squeezing, pain, or discomfort in the center of the chest that lasts for more than a few minutes
• Pain or discomfort that spreads to the shoulders, neck, arms, or jaw
• Chest pain that gets worse
• Chest pain that doesn't get better with rest or by taking nitroglycerin
• Chest pain that happens along with any of these symptoms:
• Sweating, cool, clammy skin, or paleness
• Shortness of breath
• Nausea or vomiting
• Dizziness or fainting
• Unexplained weakness or fatigue
• Rapid or irregular pulse

Although chest pain is the key warning sign of a heart attack, it may be confused with other conditions. These include indigestion, pleurisy, pneumonia, tenderness of the cartilage that attaches the front of the ribs to the breastbone, and heartburn. 

Diagnosis

Ideally, a healthcare provider should screen you during regular checkups for risk factors that can lead to a heart attack. A heart attack is often diagnosed in an emergency setting. If you've had or are having a heart attack, care providers will take immediate steps to treat your condition. If you're able to answer questions, you may be asked about your symptoms and medical history. Tests to diagnose a heart attack include:

Electrocardiogram (ECG or EKG): This first test done to diagnose a heart attack records electrical signals as they travel through the heart. Sticky patches (electrodes) are attached to the chest and sometimes the arms and legs. Signals are recorded as waves displayed on a monitor or printed on paper. An ECG can show if you are having or have had a heart attack.

Blood tests: Certain heart proteins slowly leak into the blood after heart damage from a heart attack. Blood tests can be done to check for these proteins (cardiac markers).

Chest X-ray: A chest X-ray shows the condition and size of the heart and lungs.

Echocardiogram: Sound waves (ultrasound) create images of the moving heart. This test can show how blood moves through the heart and heart valves. An echocardiogram can help identify whether an area of your heart has been damaged.

Coronary catheterization (angiogram): A long, thin tube (catheter) is inserted into an artery, usually in the leg, and guided to the heart. Dye flows through the catheter to help the arteries show up more clearly on images made during the test.

Cardiac CT or MRI: These tests create images of the heart and chest. Cardiac CT scans use X-rays. Cardiac MRI uses a magnetic field and radio waves to create images of your heart. For both tests, you usually lie on a table that slides inside a long tubelike machine. Each test can be used to diagnose heart problems. They can help show the severity of heart damage.
