Heart attack

A heart attack (myocardial infarction, or MI) is a serious medical emergency in which the blood supply to the heart is suddenly blocked, usually by a blood clot.
A heart attack is a medical emergency. Call 999 and ask for an ambulance if you suspect a heart attack.
Lack of blood flow to the heart can severely damage the heart muscle and be life-threatening.
Symptoms of a heart attack may include:

Chest pain: a feeling of pressure, heaviness, tightness, or tightness in the chest

pain in other parts of the body: may feel as if the pain is spreading from the chest on the arms (usually the left arm but can affect both arms), jaw, neck, back and abdomen from nausea) or nausea (vomiting)

an overwhelming feeling of anxiety (similar to a panic attack)

coughing or wheezing

pain in of the chest are usually severe, but some people may experience only mild pain, similar to an indigestion.While the most common symptom in both men and women is chest pain, women are more likely to have other symptoms, such as shortness of breath, nausea, and back or jaw pain.
Call 999 immediately if you think someone might be having a heart attack. The faster you act, the better your chances.

Heart attack treatment

While waiting for an ambulance, it may be helpful to chew and then swallow an aspirin tablet (ideally 300 mg), provided the person having a heart attack is not allergic to aspirin.
Aspirin helps thin the blood and improves blood flow to the heart.In the hospital, the treatment of a heart attack depends on its severity.
The 2 main treatments are:

use of medicines to break up blood clots

surgery to restore blood flow to the heart

Causes of Myocardial Infarction

Coronary artery disease (CAD) is the leading cause of myocardial infarction.
CHD is a condition in which the main blood vessels that supply the heart become clogged with cholesterol deposits known as plaques.
Before a heart attack occurs, one of the plaques ruptures (ruptures), causing a blood clot to form at the site of the rupture.
The clot can block blood flow to the heart and cause a heart attack.

Recovering from a Heart Attack

The time it takes to recover from a heart attack depends on the extent of damage to the heart muscle.Most people can return to work after a heart attack. Some people are healthy enough to go back to work after 2 weeks. Other people can take several months to recover. How soon you can get back to work depends on your health, the condition of your heart and the nature of your work.
The recovery process aims to:

reduce the risk of having another heart attack through a combination of lifestyle changes (e.g. eating a healthy diet) and medications (e.g. statins) that help lower the levels of cholesterol in your blood

gradually restore your physical condition so you can resume normal activities (cardiac rehabilitation)

Complications of a heart attack

Complications of a heart attack can be serious and potentially fatal.These include:

Arrhythmias: These are abnormal heartbeats. Type 1 is when the heart starts beating faster and faster and then stops (cardiac arrest)

Cardiogenic shock: when the heart muscles are severely damaged and unable to contract properly to supply enough blood to perform many functions in the body

Heart rupture – where the heart’s muscles, walls or valves separate (rupture)

These complications can occur quickly after a heart attack and are a leading cause of death.
Many people die suddenly from a heart attack complication before reaching the hospital or within the first month after a heart attack.
Prognosis often depends on:

age – serious complications are more likely with age

severity of heart attack – how badly the heart muscle was damaged during the attack

how long it took a person to receive treatment: treatment for a Heart attack should begin as soon as possible
