Heart Attack

What Is a Heart Attack?

A heart attack is a critical medical condition where the blood flow to the heart is severely reduced due to blockage or congestion. The blockage is usually due to prolonged build-up of cholesterol (plaque), fat, etc. that results in coronary heart diseases.

In some cases, the plaque ruptures causing a clot that restricts the blood flow to the heart. Eventually, the lack of blood in the heart may lead to serious damage to the heart muscles. Therefore, it is important to seek medical care from the doctor to restore blood flow and prevent cardiovascular damage. You can consult our doctor for Heart Attack treatment in Kolkata for timely diagnosis and advanced care.  

The heart muscles may get damaged and begin to die. Without treatment, the heart muscles will experience irreversible damage and may die.

There are three types of heart attacks - 

  • ST-segment elevation myocardial infarction (STEMI) - These types of heart attacks are severe and require immediate medical attention. These attacks occur when the coronary artery is fully blocked which can cause progressive damage to the heart muscles. 
  • Non-ST segment elevation myocardial infarction (NSTEMI) - These heart attacks occur when the blood flow is partially restricted. While such heart attacks may not be fatal, they can cause permanent damage to the heart muscles.
  • Coronary spasm, or unstable angina - Also termed as silent heart attacks or unstable angina occurs when the blood flow to the heart is restricted by the arteries connected to the heart contract. The symptoms of coronary heart spasms can mimic other medical conditions like indigestion. Therefore, it is important to distinguish the heart attack symptoms for timely treatment.
