What is myocardial infarction?
Myocardial infarction is, in fact, what we call a heart attack. A heart attack is caused when a blood clot gets stuck in the coronary arteries i.e. the arteries supplying blood to the heart muscles. As the blood flow is blocked by the clot, the heart muscle does not get oxygen-rich blood causing the heart muscle to die. Heart attacks can be fatal if not treated quickly. Over time, patients who have had heart attack can develop conditions like chronic heart failure.
A heart attack can occur when:
- At rest
- After excessive physical activity or physical stress
- After sudden emotional stress
Common heart attack symptoms include:
- Pressure, tightness, pain, or a squeezing or aching feeling in the chest or arms that may spread to the neck, jaw or back
- Nausea, indigestion or stomach pain
- Excessive sweating
- Trouble sleeping
- Lightheadedness or dizziness
However, some people can have very mild symptoms or no symptoms at all.
Common diagnostic tools:
It is important to get immediate medical help you think you are suffering from any of the heart attack symptoms. Once in the hospital, your doctor will give you emergency treatment to ensure your heart suffers minimum damage due to the attack. Tests are then conducted to assess the severity of the attack.
ECG (Electrocardiogram): If you have had a heart attack, your ECG will be abnormal.
Stress Test: A stress test shows how your heart works during intense activities. It involves:
- 15-minute walk on treadmill
- ECG(Electrocardiogram) at rest and after walk
Angiography / Cardiac catheterization: During angiography, a special dye is injected into your blood through a thin tube or catheter which is inserted into a larger artery and then directed to the arteries of the heart. The dye clearly shows any blockages you might have.
Echocardiography: In this test, ultrasound waves are directed to the heart through a device called transducer. Different areas bounce off the waves differently these waves are picked up by a recording device to create moving pictures of your heart.
Treatment at Madhavbaug™
Post heart attack, cardiac rehabilitation is necessary for patients to get used to their changed health status, control their symptoms, reverse or retard hardening and narrowing of arteries and reduce risk of further complications. At Madhavbaug™, we check the functional capacity of the patient’s heart and offer treatment programmes accordingly.
Important: If someone is showing symptoms of a heart attack, call an ambulance or drive the person to a hospital as soon as possible. If you yourself are showing symptoms, please do not drive. Ask for help quickly. Your timely action can save lives.
