Heart attack symptoms
Heart attack symptoms can include:
- A sensation of pressure, weight, tightness, or squeezing across your chest is known as chest pain.
- pain in other bodily areas, such as the jaw, neck, back, and stomach, can seem to be radiating from your chest to your arms (typically the left arm, but it can impact both).
- feeling faint or lightheaded
- perspiring
- breathlessness
- Being ill (vomiting) or experiencing nausea
- a strong sense of unease that is comparable to a panic attack
wheeze or coughing
While the pain in the chest is usually quite intense, some people may just feel a slight discomfort, akin to indigestion.
Although chest pain is the most typical symptom, each individual may experience different symptoms. Some individuals may experience other symptoms in addition to chest discomfort, such as dyspnea, nausea, and jaw or back pain.
In the event that you believe someone is experiencing a cardiac arrest , dial 999 right away. Their odds increase with the speed at which you act.
Taking care of heart attacks
As long as the individual experiencing a cardiac arrest is not allergic to aspirin, it may be helpful to chew and then take an aspirin tablet (preferably 300 mg) while waiting for an ambulance.
Aspirin enhances blood flow to the heart and thins the blood.
The type and severity of a heart attack determine the course of treatment at a hospital.
The two primary therapies are:
- using medications to break up blood clots
- surgery to assist in supplying the heart with blood
causes of cardiac arrest
- attacks are mostly caused by coronary heart disease (CHD).
- A build-uHeart p of deposits of fatty substances, called plaques, clogs the major blood vessels (coronary arteries) supplying the heart muscle in patients with congestive heart disease (CHD).
- One of the plaques bursts (ruptures) prior to a heart attack, resulting in the development of a blood clot at the rupture site.
- A heart attack could be brought on by the clot obstructing the heart’s blood flow.
Getting well after a cardiac arrest
The degree of damage to your heart muscle will determine how long it takes for you to recover after a heart attack.
Most heart attack survivors are able to resume their jobs. Your health, your heart’s condition, and the nature of your profession will determine how soon you can return to work.
The procedure of recuperation seeks to:
- Use medication (like statins), which lower blood cholesterol, in conjunction with lifestyle modifications (such eating a healthy diet) to lessen your chance of having another heart attack.
- progressively get back into shape so you can carry on with your regular activities (cardiac rehabilitation)
consequences of a heart attack
Cardiac arrest complications can be extremely dangerous and even fatal.
Among them are:
- Heartbeat irregularities are known as arrhythmias. Certain varieties can halt heartbeat
- Heart-muscle injury that prevents the heart from contracting correctly enough to pump enough blood to support numerous bodily processes is known as cardiogenic shock.
- cardiac rupture, or the breaking apart of the heart’s walls, muscles, or valves
These complications are a major cause of death following a cardiac arrest and can occur quickly.
Before arriving at the hospital or within the first month following a heart attack, some people pass away unexpectedly from a heart attack-related complication. However, a lot of people can survive a heart attack with treatment.
The prognosis frequently hinges on:
- age: As you age, significant issues are more likely to occur.
- how much of the heart’s muscle was destroyed .
- The earliest feasible start of treatment is recommended for a cardiac arrest.
- overall wellness
