A heart attack is a medical emergency. A heart attack usually arises when a blood clot blocks blood flow to the heart. Without blood, the tissue drops oxygen and dies.
Symptoms include a feeling of tightness or pain in your chest, neck, back, or arms, as well as fatigue, drowsiness, irregular heartbeat, and anxiety. Women have more atypical symptoms than men.
Treatment ranges from lifestyle changes and cardiovascular rehabilitation to medications, stents, and bypass surgery.
What is a Heart Attack?
A heart attack occurs when the torrent of oxygen-rich blood through one or more coronary arteries supplying the heart muscle is suddenly blocked, and part of the muscle is not getting enough oxygen. Clogging usually occurs when the plate breaks. If blood flow is not restored quickly, be it medication to dissolve the blockage or a catheter inserted into an artery to physically open the blockage, a portion of the heart muscle begins to die off.
Difference between a Heart Attack
The heart is a muscular organ that hearts blood throughout the body. This function provides your organs and tissues with oxygen and vital nutrients.
Heart disease prevents the heart from working correctly and can have serious health consequences. The United States Centers for Disease Control and Prevention (CDC) estimates that one in four deaths in the United States each year is due to heart disease.
Heart attack and heart disappointment are two conditions that affect the heart and can affect your health if left whole. However, they are not the same object, and several key differences between the two conditions exist.
Heart failure happens when the heart cannot pump much blood to meet your body’s organs and skin needs. The CDC estimates that 6.2 million adults in the United States are living with heart failure.
Different Types of Heart Failure
1. Left Heart Failure
Among the different types of heart failure, left-sided heart failure is the most common.
Left heart failure occurs when the side of the heart that pumps oxygenated blood into body tissue is affected. There are two types of left ventricular failure:
Systolic: Systolic failure is also known as ejection fraction heart failure. It happens when the left ventricle of the heart is unable to pump blood to the heart efficiently.
Diastolic: Diastolic failure is also known as preserved ejection fraction heart failure. When the left ventricle becomes stiff and unable to relax between heartbeats, it cannot fill enough blood.
2. Right Heart Failure
Right-sided heart failure affects the part of the heart that receives deoxygenated blood from the body. When heart failure occurs, the heart cannot pump blood to the lungs for oxygen.
What are the Causes of a Heart Attack?
One of the leading causes of heart attack is ischemic heart disease, characterized by a contraction of the coronary arteries. Ischemic heart disease typically results from arteriosclerosis: the thickening and hardening of the walls of the streets. Blood circulation in the heart muscle can also affect by other blood vessel disorders, scar tissue, heart failure, or other heart rhythm disorders.
Patients at risk of heart attack are those with a genetic predisposition, men over 45, women over 55, and bypass patients. It is not possible to influence these factors.
However, you can reduce or mitigate the following risk factors with proper treatment or lifestyle changes:
- Hypertension (high blood pressure)
- High levels of lipids in the blood, especially “bad” cholesterol (LDL)
- Overweight or obese
- Lack of exercise
How is a Heart Attack Diagnosed?
The most important test to diagnose a heart attack quickly is the electrocardiogram. If the electrocardiogram results confirm a heart attack, the electrical activity of the heart will need to observe during emergency treatment to detect any heart rhythm disturbances early.
Having done this, the medical team will need to locate the heart’s affected part and the coronary artery’s blockage. Echocardiography will carry out to do: an ultrasound examination of the nature. The coronary arteries are usually examined with a catheter in the hospital’s catheterization laboratory. Also, blood tests will be carried out to determine if a heart attack occurs and how serious the matter is. Other tests, such as CT scans or MRIs, can provide more information.
