How Do Heart Attacks Happen?
A Heart Attack occurs when anything prevents your heart from receiving the oxygen it needs in the form of blood flow.
Every year, more than a million Americans get heart attacks. Myocardial infarctions are extra name for a heart dose (MI). The terms “myo,” “cardial,” and “infarction” all relay to the death of skin brought on by a lack of family flow. Your heart force may suffer lifelong harm as a result of this might loss.
Heart Attack Warning Signs
Heart attack signs and symptoms include:
- Pain, pressure, heaviness, tightness, or discomfort under your breastbone, in your arm, or in your chest.
- Aches and pains in your arm, back, jaw, or throat
- Feelings of suffocation, indigestion, or fullness (it may feel like heartburn)
- Sweating, nausea, vomiting, or lightheadedness
- Extreme weariness, Anxiety, drowsiness, or shortness of breath
- Rapid or erratic heartbeat
The signs and symptoms of a heart attack can vary from one individual or attack to attack. These signs and symptoms of a heart attack are more common in women:
- Unusual tiredness
- Vomiting or nauseous
- Unsteadiness or faintness
- Digestive discomfort. Indigestion could be the sensation.
- Pain in the upper back, shoulders, or neck
Some heart attacks cause no symptoms at all (a “silent” myocardial infarction). Diabetes sufferers are more likely to experience this.
Angina is not a disease or condition. It is a symptom that occasionally can indicate a heart attack. The symptoms could be brought on by routine tasks or exercise, but they would disappear after resting or taking nitroglycerin.
You could feel:
In the middle of the chest, there may be pressure, pain, squeezing, or a sense of fullness.
Discomfort or pain in the jaw, neck, back, shoulder, or arm
Call 911 if discomfort persists after taking nitroglycerin for more than five minutes or if it worsens. That condition is known as “unstable” angina and is a medical emergency that may be connected to an impending heart attack.
Instead, if you have “stable” angina, the most prevalent form, your symptoms typically occur with predictable causes (such as a strong emotion, physical activity, extreme hot and cold temperatures, or even a heavy meal). If you get some rest or take the nitroglycerin your doctor suggested, the symptoms go away.
Causes of heart attacks
Your heart muscle requires a continual flow of blood that is rich in oxygen. The vital blood supply to your heart is provide by your coronary arteries. When you have coronary artery disease, your arteries become narrow, which reduces blood flow. You get a heart attack when your blood supply is cut off.
In your arteries, plaques are created by the accumulation of fat, calcium, proteins, and inflammatory cells. These plaque deposits have a hard exterior and a soft, mushy interior.
The surface shell of the plate fractures when it suits firm. We refer to this as a rupture. Blood clots form around the plaque when platelets, which are disc-shape components of your blood that aid in clotting, travel to the area. Your heart muscle will become oxygen-starve if a blood clot plugs an artery. The quick death of the muscle cells results in lasting harm.
How Should I Respond to a Heart Attack?
You require prompt medical attention after a heart attack to unblock the artery and limit the damage. Call 911 as soon as you notice any heart attack symptoms. One to two hours after the first signs of a heart attack are when treatment is most effective. Your heart will suffer more harm and you have a decrease chance of surviving if you wait longer.
While you’re waiting for emergency services to come after calling them, take an aspirin (325 mg). Aspirin has a strong blood clot-inhibiting effect and can reduce the chance of dying from a heart attack by 25%.
If Someone Else Has a Heart Attack, What Should I Do?
If someone has cardiac arrest, which occurs when the heart has stopped and the individual is not breathing, dial 911 and begin CPR. Although CPR doesn’t restart the heart, it keeps the patient alive until emergency help can be provide.
AEDs (automated external defibrillators) are accessible in many public locations and can be use to treat cardiac arrest by virtually anyone. By shocking the heart back into a regular beat, this device works.
An AED should be used as follows:
Verify the responsiveness
To determine whether an adult or older child is unconscious, shout at them and give them a strong shake. On a conscious person, do not use an AED.
Pinch the skin of a newborn or young child. Never shake an infant.
check your pulse and breathing. Prepare to use the AED as soon as possible if present or unequal.
Get ready to use an AED
Make sure the person is away from any puddles or water and in a dry environment.
Examine the person’s physique for body piercings or the outline of any medical implants, such as pacemakers or implantable defibrillators.
The distance between AED pads and piercings or implant devices must be at least 1 inch.
Use a paediatric AED when treating newborns, babies, and kids up to age 8 if at all possible. Use an adult AED if not.
- Start the AED.
- Dry-clean the chest.
- Fasten pads.
- If necessary, attach the connector.
- Verify that nobody is touching the subject.
- Select “Analyze” from the menu.
- Double-check to make sure no one is touching the victim if a shock is recommend.
- Select “Shock” from the menu.
- Begin or continue the compressions.
Check the person’s cardiac beat after performing CPR for two minutes. Give them another shock if it’s still erratic or absent.
Continue CPR if a shock is not required until emergency help comes if the victim starts to move.
Keep the person close until assistance arrives.
Heart Attack Detection
Your symptoms will be discussed with you by emergency personnel, who will also do various tests.
Treatment for Heart Attack
In order to avoid lasting heart damage or death, a heart attack is a medical emergency that requires quick attention. If you dial 911, treatment frequently starts in the ambulance or the emergency department if someone else drove you there.
What medications are prescribe for heart attacks?
You will receive medications to stop further blood clotting in the heart and lessen the strain on the heart as soon as you arrive at the emergency facility or hospital. Drug therapy tries to stabilise the plaque, break up or halt blood clots, prevent platelets from adhering to the plaque and causing additional ischemia.
To minimise cardiac damage, you should take these medications as soon as you can (ideally, within 1 or 2 hours of the beginning of your heart attack).
Drugs that may be taken during a heart attack include:
- Aspirin to prevent blood clotting that could exacerbate a heart attack
- Additional antiplatelet medications to prevent clotting, such as clopidogrel (Plavix), prasugrel (Effient), or ticagrelor (Brilinta).
- Blood clots in your heart’s arteries can be removed with thrombolytic therapy (also known as “clot busters”).
- Any medley of these
Guidelines for Preventing Heart Attacks
Maintaining heart health and reducing the chance of suffering another heart attack are the two main objectives following a heart attack. Take your medications as prescribe, adopt a healthy lifestyle, schedule routine heart exams with your doctor, and think about enrolling in a cardiac rehabilitation programme.
After I leave the hospital, when will I next see my doctor?
After a heart attack, schedule a doctor’s visit for 4 to 6 weeks after you leave the hospital. Your recuperation will be monitored by your doctor. You could require regular exercise stress testing. With the use of these tests, your doctor can identify or lessen coronary artery blockages and make treatment plans.
If you experience symptoms like chest discomfort that occurs more frequently, intensifies, lasts longer, or extends to other places, as well as shortness of breath, particularly while you’re resting, dizziness, and irregular heartbeats, call your doctor right on0 200
