What is a heart attack?

A heart attack occurs when something blocks blood flow to the heart, preventing it from getting the oxygen it needs. This is a medical emergency. As soon as symptoms develop, call 911 immediately. Do not wait until symptoms go away. A heart attack is also called a myocardial infarction “Mio” refers to muscle, “cardiac” refers to the heart, and “infarction” refers to tissue death due to lack of blood supply. This tissue death can permanently damage your heart muscle.

Heart attack symptoms

Symptoms of a heart attack include:

  • Discomfort, pressure, heaviness, tightness, bruising, or pain in the chest, arms, or just below the breastbone
  • Discomfort in the back, jaw, neck, or arms
  • Bloating, indigestion, or choking feeling (may feel like heartburn)
  • Sweating, upset stomach, vomiting, or dizziness
  • Severe weakness, anxiety, tiredness, or shortness of breath
  • Fast or uneven heartbeat

Symptoms may vary from person to person, or from one heart attack to another. The following heart attack symptoms are more prevalent in women:

  • Unusual fatigue
  • Breathing difficulty
  • Nausea or diarrhoea
  • Unsteadiness or faintness
  • Discomfort in the stomach. Indigestion could be the sensation.
  • Neck, shoulder, or upper back discomfort
  • Information on Heart Attacks

Annual heart attacks affect more than a million Americans.  The CDC estimates that someone in the United States experiences it every 40 seconds.

Men and women both experience heart attacks. Numerous risk factors, such as high blood pressure, high levels of LDL (“bad”) cholesterol, diabetes, and whether you smoke, are alterable, despite the fact that they become more likely as you age.

Types of heart attacks: The following phrases may be used to describe a heart attack:

A heart attack known as a STEMI occurs when the entire coronary artery is occluded.

  • NSTEMI: A heart attack in which a coronary artery is significantly constricted but not completely blocked
  • MINOCA: A heart attack in which the main coronary arteries are not shown to be blocked. Myocardial infarction with non-obstructive coronary arteries is known as MINOCA.

Actually, a heart attack is not a sudden cardiac arrest. Consider a heart attack as an issue with the heart’s arteries, and a sudden cardiac arrest as the electrical system of the heart suddenly malfunctioning and preventing the heart from pumping blood.

A heart attack is not what angina is either. It’s a hint that occasionally a heart attack may be imminent. It indicates chest pain. It can also occur for other reasons in addition to heart attacks. When you relax or take nitroglycerin, the sensations may disappear. They may also appear during routine activity or exertion.

Call 9-1-1 if you notice symptoms of a heart attack.

One sign of angina is:

  • You can experience pressure, pain, squeezing, or a feeling that your chest is full if you have angina.
  • Shoulder, arm, back, neck, or jaw ache or pain

Call 911 if discomfort persists after taking nitroglycerin for more than five minutes, grows worse, or doesn’t get better. That is what medical professionals refer to as “unstable” angina, and it is an emergency that may be connected to an impending heart attack.

As an alternative, if you have “stable” angina, which is the most typical type. Your symptoms will typically occur in response to known triggers (such as intense feelings, physical activity, extremely high or low temperatures, or even a large meal). Resting or taking the nitroglycerin that your doctor has given will relieve the symptoms. Call 911 if not.

Causes of Heart Attack

Blood that is rich in oxygen is necessary for your heart muscle to function continuously. Your heart receives this essential blood supply through your coronary arteries. If you have coronary artery disease, your arteries constrict, which reduces blood flow. A heart attack happens when your blood supply is cut off. Your arteries develop plaques as a result of the accumulation of fat, calcium, proteins, and inflammatory cells. These plaque deposits are firm on the outside and mushy and soft on the inside.

The plaque’s outer shell splits when it becomes too hard. This is referred to as a rupture. Blood clots develop around the plaque as platelets, which are disc-shaped components of your blood that help it clot, travel to the area. Your heart muscle is deprived of oxygen if a blood clot narrows one of your arteries. Rapid cell death results in long-term harm to the muscle.

Who is at risk for a heart attack?

A heart attack might sporadically result from a spasm in your coronary artery. Your arteries narrow or spasm intermittently during a coronary spasm, preventing blood flow to your heart muscle (ischemia). Even if you don’t have substantial coronary artery disease, it can occur when you’re at rest.

A separate area of your heart muscle is served by each coronary artery. The area that the blocked artery serves and the duration between the attack and therapy determine how much damage is done to the muscle.

Soon after a heart attack, your heart muscle begins to recover. 8 weeks are required for this. The damaged area develops a scar, just like a skin wound. The new scar tissue does not, however, migrate naturally. As a result, following a heart attack, your heart cannot pump as much. The size and placement of the scar will determine how much it affects your ability to pump.

Having a heart attack: What Should I Do?

To unblock the clogged artery and limit the damage after a heart attack, immediate therapy is necessary. Call 911 as soon as a heart attack begins to show symptoms. Within 1 to 2 hours of the onset of symptoms, a heart attack is most effectively treated. More cardiac damage and a worse chance of survival result from waiting longer.

Chew a 325 mg aspirin as you wait for emergency services to arrive after you’ve phoned them. A heart attack’s risk of death can be reduced by 25% thanks to aspirin, a powerful blood clot inhibitor.

What Should I Do If Another Person Has a Heart Attack?

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 provided.

AEDs (automated external defibrillators) are accessible in many public locations and can be used 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:

  1. 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.
  1. 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 implanted devices must be at least 1 inch.
  1. Employ an AED

Use a pediatric AED when treating newborns, babies, and kids up to age 8 if at all possible. Use an adult AED if not.

  • Activate the AED.
  • Dry-clean the chest.
  • Fix the pads.
  • If necessary, connect the connector.
  • Ensure that nobody is contacting the person.
  • Click “Analyze” to start.
  • If a shock is suggested, double-check that nobody is touching the subject.
  • Select “Shock” from the menu.
  • Begin or continue compression.
  • Observe the AED’s instructions.
  1. Maintain CPR
  • 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.
  • Till help arrives, keep the person near.
  • Heart Attack Detection
  • Your symptoms will be discussed with you by emergency personnel, who will also do various tests.

Heart attack diagnosis tests

Your physician might recommend testing such as:

EKG: Electrocardiogram, or EKG, is a straightforward diagnostic that captures the electrical activity of the heart. It can identify the locations and extent of cardiac muscle injury your heart rate and rhythm can also be observed.

Blood tests: A number of blood tests, frequently performed every 4 to 8 hours, can aid in the diagnosis of a heart attack and identify any lingering cardiac damage. Different cardiac enzyme levels in your blood may signify damaged heart muscle. The cells in your heart often contain these enzymes. These cells’ contents, which includes the enzymes, leak into your bloodstream when they are damaged. Your doctor can determine the magnitude and timing of the heart attack by checking the levels of these enzymes. Troponin levels can also be determined via tests. Troponins are proteins that are found inside heart cells and are released when the cells are harmed due to your heart’s lack of blood flow.

When an echocardiogram is used

Echocardiography: During this ultrasound examination, sound waves are reflected off your heart to produce images. It can be used both during and after a heart attack to determine how your heart is beating and which parts aren’t functioning properly. The “echo” can also detect any damage to your heart’s valves or septum.

Cardiac catheterization: If drugs aren’t alleviating the symptoms or ischemia in the early stages of a heart attack, you may need cardiac catheterization, also known as cardiac cath. The cardiac catheter can provide a picture of the blocked artery and aid in therapy selection for your doctor.

A catheter, a small, hollow tube, is threaded up to your heart during this surgery and is put into a blood vessel in your wrist or groin. Your heart’s arteries are highlighted by dye. Once blockages are found, they are frequently treated with angioplasty or stents to unblock the artery and restore blood flow. Your doctor may do a number of tests to evaluate your heart. In the absence of cardiac catheterization, intravenous blood thinner can be used to open the artery.

Stress testing: Your doctor can perform a radionuclide scan or a treadmill test to see whether other parts of the heart are still vulnerable to having another heart attack.

Treatment for Heart Attack

In order to avoid lasting heart damage or death, a heart attack is a medical emergency that requires immediate attention. If you dialed 911, treatment frequently starts in the ambulance or the emergency department if someone else drove you there.

What medications are prescribed 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 stabilize the plaque, break up or halt blood clots, prevent platelets from adhering to the plaque and causing additional ischemia. To minimize heart damage, you should acquire these medications as soon as you can (ideally within 1 or 2 hours of the start 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
  • Other antiplatelet medications to prevent clotting include clopidogrel (Plavix), prasugrel (Effient), and ticagrelor (Brilinta).
  • Dissolving blood clots in your heart’s arteries with thrombolytic therapy (also known as “clot busters”).
  • Any combination of these additional medications taken during or after a heart attack can improve heart function, widen blood arteries, lessen discomfort, and prevent potentially fatal heart rhythms.

Are there any further therapies for heart attacks?

A technique to unblock the clogged arteries may potentially be used as treatment. Cardiac catheterization can be used for operations (such as angiography or stent) to open blocked or restricted arteries in addition to taking an image of your arteries.

Balloon angioplasty: If necessary, this treatment can be carried out via cardiac catheterization. A narrow, hollow tube with a balloon tip is placed into the heart’s obstructed artery. The balloon is gradually inflated to push the plaque against the arterial walls outward in order to widen the artery and increase blood flow. Most of the time, a stent must be implanted in order to perform this.

Stent placement: In this technique, a tiny tube is introduced into a blocked artery using a catheter to “prop” the artery open. The stent is typically permanent and constructed of metal. It might also be constructed from a substance that your body gradually absorbs. Some stents contain medication that aids in preventing the artery from being blocked once more.

Bypass surgery: Following a heart attack, you could undergo bypass surgery to reestablish your heart’s blood flow. By using a blood channel from your leg or chest, your surgeon will reroute blood flow around your blocked artery. They can skip several arteries.

How does the coronary care unit (CCU) operate?

You’ll typically spend at least 24 to 36 hours in a CCU after having a heart attack. Once you have passed the critical stage, you will continue to receive a range of medications, such as:

  • Beta-blockers to reduce heart rate
  • Increased cardiac blood flow with nitrates
  • To stop further clotting, take blood thinners such aspirin, Brilinta, clopidogrel, Effient, heparin, or Plavix.
  • ACE inhibitors can speed up cardiac muscle recovery.
  • Statins, which include atorvastatin and simvastatin, lower cholesterol and reduce the risk of heart attacks by promoting the healing of the heart muscle.
  • In case you experience atypical cardiac rhythms while you are in the hospital, medical professionals will continuously monitor your heart using an EKG.

Some people might require the installation of a pacemaker, a battery-operated device that helps maintain a constant heartbeat. Medical professionals will shock your chest with electricity if you have the risky arrhythmia ventricular fibrillation. Coronary artery disease cannot be cured by treatments. Still, you could get another heart attack. However, you can take measures to reduce its likelihood.

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 prescribed, adopt a healthy lifestyle, schedule routine heart exams with your doctor, and think about enrolling in a cardiac rehabilitation program.

Why must I take drugs following a heart attack?

Following a heart attack, you might need specific medications to:

  • Stop blood clots
  • Make your heart more efficient
  • Reduce cholestero to avoid plaques

You may be prescribed drugs to address heart failure, blood pressure problems, irregular heartbeat, and chest pain. Know the names, functions, and dosage requirements for all of your prescription drugs. Talk to your doctor or nurse about your meds. Keep a list of all your prescription drugs and bring it with you to every doctor’s appointment. Ask your doctor or pharmacist about them if you have any questions.

Do not miss your medication, even what might seem clear. Many people do not take their prescriptions as prescribed by their doctors. Ask your doctor for assistance in identifying the problem(s) that prevent you from taking your medication, which may be adverse effects, expense, or forgetfulness.

After a heart attack, what dietary adjustments are necessary?

Follow your doctor’s instructions to prevent heart disease from worsening and preventing another heart attack. Your way of life may need to change. You may reduce your risk and start living a healthier life by making the following changes:

Don’t smoke: Heart attacks and strokes are far more likely to occur if you smoke. You should discuss quitting with your doctor. Secondhand smoking can also cause heart disease, so you’ll also be doing your loved ones and friends a favor. Along with visiting smokefree.gov, you can also call the 800-QUIT-NOW hotline (800-784-8669).

Maintain a healthy weight: If you are overweight or obese, your doctor may advise some weight loss even though you don’t need to become skinny in order to lower your risk for a heart attack or stroke. Your cholesterol numbers will improve, and your blood pressure, blood sugar, and blood sugar levels will all decrease if you lose 5% to 10% of your body weight.

Exercise and Diet for a Healthy Heart

Follow a workout routine: Your risk of having a heart attack is reduced by moderate physical activity. Additionally, it can help you maintain a healthy weight while lowering your blood pressure and LDL or “bad” cholesterol and raising HDL or “good” cholesterol. At least 5 days a week, try to get in 30 minutes of heart-pumping activity. Swimming or brisk walking are two excellent options. Perform strength training, such as lifting weights, on the other two days. If you have a busy schedule, divide your exercise regimen into manageable halves.

Consume heart-healthy foods: Put a variety of fruits, vegetables, legumes, and lean meats on your meal, including chicken without the skin. Increase your consumption of fish, particularly omega-3-rich fish like salmon, trout, and herring, as well as nutritious grains like oats, quinoa, and brown rice.

Eat a heart-healthy diet: Omega-3s are also present in various nuts and seeds, avocados, olive oil, and flaxseeds. Dairy products like milk, yogurt, and cheese that are fat-free or low in fat are also better for your heart health than counterparts that are higher in fat.

How Does an Unhealthy and Alcoholic Diet Raise Your Risk of Heart Disease?

Cut back on unhealthy foods: Reduce your intake of unhealthy foods by avoiding processed or prepared foods, which are frequently loaded with salt and added sugar. Additionally, preservatives are present in them. Steer clear of butter, fried foods, fatty steak, and palm oil. All include a lot of saturated fats. Avoid consuming fruit punch and other sugary drinks that can cause weight gain. The same is true for packaged baked items including pies, cakes, and cookies. They can cause your cholesterol to rise since they are heavy in trans fats.

Limit alcohol: Drink in moderation; if you don’t already, refrain from starting. If you do drink, keep your intake to a minimum. It is advised to limit your alcohol consumption to one drink per day for women and two drinks per day for males. Drinking increases blood pressure and heart rate. Additionally, it increases blood fat levels and promotes weight growth.

How is high cholesterol diagnosed?

Levels, and cholesterol: Make sure your diabetes is under control if you have it. You can become more aware of the adjustments you need to make to keep these levels within typical ranges by keeping an eye on these statistics.

Reduce stress: At times, you might experience anxiety or frustration. Tell your loved ones and friends what’s going on. You can discover how others adapted to life after a heart attack or stroke by joining support groups.

Ask your doctor about a stress management program or speak with a mental health professional. Along with getting enough of exercise, you can lower your stress levels by engaging in mind-body activities like meditation.

Pay attention to your symptoms: Be aware of your symptoms; don’t just wish them away. If you experience any strange symptoms, such as shortness of breath, changes in your heart rate, or extreme exhaustion, consult your doctor. Watch out for any flu-like symptoms, back or jaw pain, sweating, nausea, or vomiting.

What makes cardiac rehabilitation important to me?

Your doctor might suggest cardiac rehabilitation if you’ve had a heart attack or been told you have heart disease. To improve your health and ward off potential issues, you’ll collaborate with a group of specialists.

Doctors and nurses could be on your team, along with experts in nutrition, physical therapy, occupational therapy, and mental health. They’ll design a plan around your requirements. You can also use them to modify the way you live. Your recuperation and general well-being may much improve if you persevere.

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 any symptoms, including chest discomfort that occurs. More frequently, intensifies, lasts longer, or spreads to other regions, shortness of breath, particularly. When you’re resting, dizziness, or irregular heartbeats, call your doctor right once.
