What is myocardial infraction?

Overview. A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don't get enough oxygen. This happens when blood flow to the heart muscle is blocked.

What myocardial infarction means?

Heart Attack (Myocardial Infarction) A heart attack (medically known as a myocardial infarction) is a deadly medical emergency where your heart muscle begins to die because it isn't getting enough blood flow. This is usually caused by a blockage in the arteries that supply blood to your heart.

What are the 5 types of myocardial infarction?

ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) coronary spasm, or unstable angina.

What triggers myocardial infarction?

Myocardial infarction (MI) is characterized by an extended subclinical phase leading to the sudden onset of life-threatening acute events (Figure). Acute MI is often preceded by specific triggers, which may include common activities such as alcohol consumption, heavy meals, physical exertion, and stressful events.

Can a myocardial infarction be detected in an ECG?

Diagnosis of myocardial infarction is confirmed based on clinical manifestations and electrocardiographic changes along with increased cardiac enzymes. Electrocardiogram (ECG) is one of the safest and easiest methods in the first place.

How is myocardial infarction treated?

The treatment of MI includes, aspirin tablets, and to dissolve arterial blockage injection of thrombolytic or clot dissolving drugs such as tissue plasminogen activator, streptokinase or urokinase in blood within 3 h of the onset of a heart attack.

How long can you live with myocardial infarction?

About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.

What is the difference between heart failure and myocardial infarction?

A heart attack occurs when there is a sudden loss of blood supply to the heart, while heart failure is when the heart is unable to pump blood efficiently.

What is the drug of choice for myocardial infarction?

The pain of myocardial infarction is usually severe and requires potent opiate analgesia. Intravenous diamorphine 2.5–5 mg (repeated as necessary) is the drug of choice and is not only a powerful analgesic but also has a useful anxiolytic effect.

What is the survival rate of heart attacks?

It is a life-threatening medical emergency and the longer this goes on without treatment, the more damage to the heart that can happen. Studies have found that survival rates for people hospitalized for heart attacks are approximately 90%2 to 97%.

Where is myocardial infarction located?

One of the most significant findings of myocardial infarction is the presence of ST segment elevation. The ST segment is the part of the ECG tracing that starts at the end of the S wave and ends at the beginning of the T wave. The point where the end of the Q wave and the ST segment meet is called the J point.

Is myocardial infarction reversible?

Myocardial infarction (MI) (ie, heart attack) is the irreversible death (necrosis) of heart muscle secondary to prolonged lack of oxygen supply (ischemia).
