Definition- When the blood supply to the heart is significantly impeded or obstructed, a heart attack happens. The accumulation of fat, cholesterol, and other chemicals in the heart's (coronary) arteries is often what causes the obstruction. Plaques are the name given to fatty, cholesterol-containing deposits. Atherosclerosis is the name for the process of plaque accumulation. A plaque may occasionally burst and generate a clot that restricts blood flow. Part of the heart muscle can be harmed or destroyed by a lack of blood flow. A myocardial infarction is another name for a heart attack.

Symptoms- Heart attack symptoms might vary. Mild signs appear in some persons. Some display serious symptoms. Some individuals show no symptoms.

Typical heart attack signs include:
  • Chest discomfort that may be felt as pressure, stiffness, soreness, hurting, or discomfort
  • Spreading to the shoulder, arm, back, neck, jaw, teeth, or even the upper belly
  • Frozen sweat
  • Fatigue
  • Acid reflux or indigestion
  • unexpected dizziness or lightheadedness
  • Nausea
  • Breathing difficulty
  • Atypical symptoms in women might include back, arm, or neck discomfort that is sudden or acute. Sudden cardiac arrest can occasionally be the initial indication of a heart attack.

Heart attacks can happen abruptly. Nonetheless, many people have warning symptoms and signals hours, days, or even weeks ahead of time. An early detection sign of angina is persistent chest pressure or discomfort that doesn't go away with rest. A brief reduction in the amount of blood flowing to the heart is what causes angina.

Causes- Your heart muscle requires a continual flow of blood that is rich in oxygen. The vital blood supply to your heart is provided by your coronary arteries. When you have coronary artery disease, your arteries grow narrow, which reduces blood flow. You get a heart attack when your blood supply is cut off.

Most heart attacks are brought on by coronary artery disease. One or more of the heart's (coronary) arteries are clogged in coronary artery disease. Plaques, which are cholesterol-containing deposits, are typically to blame for this. Plaques can cause artery narrowing, which lowers cardiac blood flow.

A plaque that ruptures may result in a cardiac blood clot.

A cardiac (coronary) artery blockage may be wholly or partially responsible for a heart attack. If an electrocardiogram (ECG or EKG) reveals any particular alterations (ST elevation) that call for urgent invasive treatment, that electrocardiogram can be used to identify heart attacks. ECG readings may be used by your doctor to characterize various kinds of heart attacks.

An ST elevation myocardial infarction is often indicated by an immediate full blockage of a medium or large heart artery (STEMI).

When you have a partial blockage, your myocardial infarction was probably non-ST elevation (NSTEMI). Nonetheless, a complete blockage might occur in certain NSTEMI patients.

Prevention- Even if you've already suffered a heart attack, it's never too late to take precautions. There are several methods to stop a heart attack.

Maintain a fit lifestyle. Avoid smoking. A heart-healthy diet will help you keep a normal weight. Manage your stress by exercising frequently.

Control further medical disorders. Heart attacks can become more likely in people who have certain diseases, such as diabetes and high blood pressure. How often you require checks can be determined by talking to your doctor.

As recommended, take your meds. Your doctor may recommend medications to safeguard and enhance the condition of your heart.

Learning CPR correctly will enable you to assist someone experiencing a heart attack. Consider enrolling in a first-aid training program that is accredited that teaches CPR and how to use an AED (AED).
