परिभाषा

A heart attack occurs when blood flow to the heart muscle is interrupted. Oxygen cannot get to the heart muscle, causing tissue damage or tissue death.

दिल का दौरा

A heart attack may be caused by:

  • Thickening of the walls of the arteries feeding the heart muscle (coronary arteries)

  • Spasm of the coronary arteries
  • Development of a blood clot in the coronary arteries
  • Embolism that affects the coronary arteries

  • लिंग पुरुष
  • उम्र बढ़ गई

निदान

परीक्षण में शामिल हो सकते हैं:

  • Blood tests—To look for certain enzymes found in the blood within hours or days after a heart attack.
  • Urine tests—To look for certain substances found in the urine within hours or days after a heart attack.
  • Electrocardiogram (EKG)—Records the heart’s activity by measuring electrical currents through the heart muscle, changes can show if there is blockage or damage.
  • Echocardiogram—Uses high-frequency sound waves (ultrasound) to examine the size, shape, function, and motion of the heart.
  • Stress test—Records the heart’s electrical activity under increased physical stress, usually done days or weeks after the heart attack.
  • Nuclear scanning—Uses radioactive material to show areas of the heart muscle where there is diminished blood flow.
  • Electron-beam computed tomography (EBCT)—A type of x-ray that uses a computer to make detailed pictures of the heart, coronary arteries, and surrounding structures.
  • Coronary angiography—Uses dye and x-rays to look for narrowing or blockage in the coronary arteries.

उपचार

उपचार में शामिल हैं:

  • ऑक्सीजन
  • Pain-relieving medicine
  • Nitrate medicines
  • Aspirin and other antiplatelet agents
  • Beta-blockers and/or angiotensin-converting enzyme (ACE) inhibitor medicines
  • Anti-anxiety medicine
  • Cholesterol-lowering medicines (such as statin drugs)

Within the first six hours after a heart attack, you may be given medicines to break up blood clots in the coronary arteries. Other medicines that may be given include those that block the function of platelets.

सर्जरी

If you have severe blockages, you may need surgery, such as:

  • Coronary artery bypass grafting (CABG)
  • Atherectomy
  • Balloon angioplasty with or without stenting

Physical or Rehabilitative Therapy

During recovery, you may need physical or rehabilitative therapy to help you regain your strength.

Treatment for Depression

You may feel depressed after having a heart attack. Therapy and medicine can help relieve depression.

If you have a heart attack, follow your doctor’s instructions .

रोकथाम

Preventing or treating coronary artery disease may help prevent a heart attack.

  • स्वस्थ वजन बनाए रखें.
  • Begin a safe exercise program. Follow your doctor’s advice.
  • यदि आप धूम्रपान करते हैं, तो छोड़ दें।
  • Eat a healthy diet. Your diet should be low in saturated fat and rich in whole grains, fruits, and vegetables.
  • Properly treat long-term conditions, like high blood pressure, diabetes, and high cholesterol.
  • Manage stress.
  • Ask your doctor about taking a small, daily dose of aspirin.
    • Although most people are able to tolerate such a low dose of aspirin, even this small amount can rarely lead to serious bleeding, particularly from the gastrointestinal (GI) tract.
    • Aspirin may not work as well when combined with other pain medicines.
