A heart attack is a serious medical condition caused by a sudden blockage of the heart's natural blood supply. This is a life-threatening event identified and treated.
A heart attack occurs when the arteries that bring blood to the heart become blocked due to a build-up of fat and cholesterol, known as plaque. If the blockage lasts long enough, the heart is unable to receive enough oxygen, leading to tissue damage or death.
Most heart attacks are caused by coronary artery disease (CAD), in
which the arteries narrow and reduce blood flow to the heart muscle. In some cases, a complete blockage of the coronary artery, interruption of the blood supply, and later heart attack can occur. Certain factors, such as high cholesterol, high blood pressure, smoking, and diabetes, can increase the risk of a heart attack. Other risk factors include a family history of heart disease, physical inactivity, and stress.
Symptoms of a heart attack may include tightness, pain, or pain in the upper body, such as the chest, jaw, neck, arms, and back. This pain may come and go, becoming more intense over time. Other symptoms include extreme fatigue, shortness of breath, nausea, palpitations, and dizziness. A person experiencing these symptoms should seek immediate medical attention, as delay can Once a heart attack is diagnosed, the individual will begin treatment depending on the severity of the condition. In mild cases, medications such as nitroglycerin, acetylsalicylic acid (aspirin), and beta blockers are used to clear the blockage. In more severe cases, angioplasty, in which a narrow tube is inserted into the artery, may be needed to open the blockage. In some cases, bypass surgery may be necessary to increase blood flow to the heart.
To reduce the risk of a heart attack, it is important to lead a healthy lifestyle.
weight, exercising, and eating a healthy diet low in saturated fat and sugar. Also, regular medical check-ups to check cholesterol, blood pressure, and other risk factors are important. If a person experiences warning signs of a heart attack, they should seek medical attention immediately. Early diagnosis and treatment can help prevent serious damage or death from a heart attack.
