Myocardial Infarction

Myocardial Infarction

Myocardial Infarction (MI) is also referred to as a heart attack or coronary thrombosis. It is a condition where a part of the heart muscle suddenly loses blood supply. Typically, a heart attack occurs due to a thrombosis (blood clot) formed within a coronary artery. This obstructs normal blood flow to some part of the heart. If left untreated, myocardial infarction can cause damage to the heart. Besides a severe myocardial infarction can be fatal. There is shortness of breath and profuse sweating. It is essential to seek immediate medical help if you feel that you are suffering a myocardial infarction. Sudden overwhelming stress or laborious exertion or physical activity might bring on a myocardial infarction.

A heart attack is felt as a sudden and severe chest pain that may also travel up and down both arms. The pain felt during myocardial infarction lasts longer than that felt during an angina. In rare cases, a person does not feel any noticeable symptoms and is even unaware that he has suffered a heart attack. Smoking, diabetes, hypertension, high cholesterol and obesity puts a person at increased risk of heart attacks. Heart attacks are more noticed in older men and women, though there is an increasing trend for younger persons to suffer heart disease too. Female sex hormones protect women from heart disease till menopause. Heart ailments and coronary heart disease is sometimes genetic.

An ECG (electrocardiograph) can help trace your heart activity and whether you have suffered a heart attack. A Doppler ultrasound helps examine the heart valves, muscles and blood flow. A coronary angiogram is a special x-ray procedure that tests the severity of the blood vessel block with the help of a dye. The presence of certain enzymes like Troponin-I and Creatinine Kinase (CK) are indicative of a heart attack.

Hospital treatment is esential for a person suffering from a MI. The nature of the treatment hinges on the extent of damage of the heart muscle as well as the blockage of the blood vessels. Medication for dissolving the blood clot is administered. The patient is given drugs to reduce the pain and breathe easier. Beta-blocker drugs may be given to reduce the chances of another heart attacks. ACE Inhibitors may be prescribed to prevent heart failure. Balloon angioplasty may be recommended to improve blood flow to the heart.

Heart attack

A heart attack (myocardial infarction) is a condition where a blockage of a coronary artery deprives the heart muscle of oxygen. A heart attack occurs when there is excessive cholesterol plaque deposit on the coronary artery leading to a blood clot. This clot prevents supply of blood to the heart resulting in a heart attack. Chest pain that is caused due to narrowing of the blood vessels to the heart is called angina pectoris. This occurs due to insufficient supply of blood to the heart muscles. Heart cells will die and form scar tissue if normal blood flow is not replaced soon.

Conditions that contribute to a heart attack include elevated LDL cholesterol, nicotine exposure, hypertension among others. Typical symptoms of heart attack are often similar to other complaints such as squeezing fullness in the chest, hearburn, left arm pain, upper back pain and sweating along with shortness of breath.

An ECG is used to record the heart's electrical activity and can help identify areas of the heart that are oxygen-starved. This helps in immediate treatment. Prompt medical attention is vital in treating a heart attack. Early resumption of blood flow to the heart muscles is of vital importance in treating a heart attack.

Aspirin - Acetylsalicylic Acid

Developed by German chemist Felix Hoffmann in 1897, acetylsalicylic acid or Aspirin as it is popularly known is a safe and effective treatment for many an ailment ranging from moderate fever to swelling or even blood clotting. This over-the-counter medication is probably one of the widest selling drugs. Aspirin is used to treat headache, migraine, muscular pain, neuralgia and sore throat. Aspirin or acetylsalicylic acid has anti-coagulant properties as well as analgesic and antipyretic properties. This drug is a NSAID - non-steroidal anti-inflammatory drug. It is used to reduce temperature and is commonly recommended for pain relief as in the case of dental pain. Aspirin works as a pain reliever by working on the sensitivity of the nerves both at the site of the pain as well as the central nervous system. FDA has approved the use of aspirin in the following conditions:

Heart conditions : The FDA has approved the use of aspirin to reduce the risk of fatality in the event of a heart attack. Aspirin taken during a suspected heart attack can also lessen the damaging effects of the heart attack. Persons who have already suffered a heart attack or unstable angina are put on a course of aspirin to reduce the risk of another heart attack. Aspirin is also recommended for use in people who have suffered transient ischemic attack (TIA or mini-stroke). FDA has endorsed the use of low dose aspirin (75 and 325 mg) for lowering the risk of heart attack and strokes. Aspirin helps in improving blood flow through narrowed blood vessels.

Side Effects of Aspirin: Side effects from aspirin are relatively rare. If you are prone to heartburn or indigestion, ensure that you take aspirin after food. Some people experience rashes or vomiting or stomach pain. Rarely are side effects such as ringing in the ears, dizziness or mental confusion noticed. In such a case, consult a doctor immediately.

Aspirin and other salicylates should not be taken during the last 3 months of pregnancy or while breast-feeding. It is essential to keep the doctor informed if you are allergic to aspirin If you are taking medications for high blood pressure, diabetes or any anticoagulants, you must inform your physician before he prescribes aspirin.
