Everything You Should Know About the Types of Heart Attacks
January 11, 2024 by admin

Heart disease is indeed the foremost reason for sudden death around the globe, and the growing numbers are the cause for major concern. Every heart problem is life-threatening and calls for immediate medical attention. Heart attack is the medical condition where the artery of which is responsible for the continuous supply of oxygen and blood is blocked. This obstruction has the potential to stop the function of the heart permanently. A cardiac attack is called myocardial infarction in medical terms. Reach out to the best cardiologist in Chennai to know more about your heart health issues.

Heart Attacks And Their Symptoms

 Acute Coronary Syndrome is a type of heart attack. The arteries transporting blood back to the cardiac are clogged in this syndrome, resulting in a heart attack. A heart attack could cut off the oxygen delivery to the entire body, resulting in chronic organ damage.

 Heart attacks can be classified into five groups. They are,

  1. STEMI (ST-Elevation Myocardial Infarction)
  2. NSTEMI (Non-ST-Elevation Myocardial Infarction)
  3. Coronary Artery Spasm
  4. Stable Angina (Angina Pectoris)
  5. Unstable Angina


The most severe cause of heart attack is an ST-segment elevation myocardial infarction, where the artery is entirely stopped. Blood cannot reach a significant portion of the cardiac muscle because of the blocked artery. A STEMI cardiac arrest damages the heart over time and necessitates immediate medical attention.


  • A sharp ache radiates from the middle of the chest.
  • Breathing problems
  • Nausea
  • Mouth, shoulder, and forearm pain
  • Anxiety
  • Light-headedness


STEMI is a life-threatening condition that necessitates immediate revascularization or blood flow recovery through a clogged artery. Revascularization is accomplished by either administering thrombolytics intravenously or performing a primary angioplasty, which involves inserting a tube with a balloon into the blocked artery. The balloon is inflated to unblock the clogged artery, allowing blood to flow again. A stent is also inserted at the location to avoid additional obstruction. Thrombolytics, often called clot busters, were drugs that disintegrate blockages in the arteries. To know more about it, consult a cardiologist In Chennai.


 NSTEMI, as well as non-ST segment myocardial infarction, is a form of a heart attack in which your heart does not get enough oxygen. The blood vessel is only slightly obstructed in this case, yet blood flow is substantially restricted. These heart problems are less severe than STEMI cardiac arrest, yet they can still cause lifelong damage. As in the event of an NSTEMI heart attack, a coronary angiography usually reveals the severity of the arterial blockage.


 NSTEMI cardiac arrest symptoms are related to STEMI symptoms. However, side effects may be disorientation, sweat, and severe chest discomfort.


 Cardiologists use a GRACE rating to assess diagnostic accuracy. The risk is calculated using eight parameters, including:

  • Heartbeats per minute
  • Age
  • Blood pressure systolic
  • ECG ST-segment deviation
  • Creatinine level within the blood
  • The cardiac marker is elevated.
  • Killip categorization
  • At the time of admission, there was a cardiac arrest

The cardiologist will recommend the best alternative treatments after just a comprehensive assessment of the person’s present state. Low-risk patients with a blockage that can be regulated and mitigated with medicines will be prescribed by the cardiologist.

Killip categorization is the process used to classify patients with acute myocardial infarction. To forecast and categorise the risk of death, it considers the progression of heart problems and a medical examination. Consult the best cardiology hospital in Chennai to learn about NSTEMI.

Coronary Artery Spasm:

Coronary artery spasm, often called silent cardiac arrest, occurs when the arterial wall suddenly spasms, restricting blood supply to the heart. Chest pain occurs when blood circulation is impeded due to muscle tension. Once blood flow is completely cut off, a cardiac attack occurs.


 Among the signs and symptoms are:

  • Light trouble breathing that only occurs when you’re resting and which last 5 to 30 minutes
  • a sense of suffocation
  • Tightness in the chest
  • Pain that radiates from the chest to the arms, neck, or jaw
  • Treatment

Medicines, including calcium channel blockers and nitrate, can be used to treat such a kind of disease attack.

Coronary artery spasm is called prinzmetal angina in medical terms. Angina refers to chest pain, pressure, or discomfort.

Stable Angina (Angina Pectoris):

Angina is a kind of chest pain caused by reduced blood supply to the heart. As blood flow is reduced, the heart does not receive enough oxygen, which could also result in heart failure.

Angina Unstable:

Unstable angina is a type of angina that develops unexpectedly and worsens over time, ultimately resulting in cardiac arrest. Patients with unstable angina have an increased chance of having a cardiac attack. Coronary heart disease caused by atherosclerosis – plaque formation in the arterial walls – has been the most prevalent trigger of unstable angina. You can consult the best cardiologist doctor in Chennai for more clarifications.


Open-heart surgery is most commonly used to treat persons who have coronary artery disease, heart failure, heart valve disease, and related heart conditions. However, certain other conditions necessitate heart surgery, such as:

  • Problems with the valves
  • Problems with the heart’s main vessel
  • A donor’s heart is used to replace a damaged heart.

What Are The Various Types Of Open-Heart Surgery?

There are various sorts of open-heart operations available according to the health situation. Among the most common are:

Coronary Bypass Grafting: This is the most frequent type of heart operation performed by alternating the blood supply channels to the heart. The healthy arteries are typically extracted from the chest, arms, or legs.

Cardiac Valves Replacement or Repair: This heart surgery is used to repair or replace the valve with a biological or metallic valve.

Treatment for Arrhythmia: Arrhythmia is a condition in which the body doesn’t beat in a regular rhythm. During surgery, a pacemaker or an ICD is implanted inside the body to correct abnormal heartbeats. Thanks to cutting-edge technology and skilled surgeons, treatments for arrhythmia ablation are available for arrhythmia.

Heart Transplantation: This surgery is used to successfully treat heart failure by exchanging the damaged heart with a healthy heart from a donor. Reach out to the best heart specialist hospital in Chennai for any heart issues.
