What Is Septal Infarct?

Are you curious to know what is septal infarct? You have come to the right place as I am going to tell you everything about septal infarct in a very simple explanation. Without further discussion let’s begin to know what is septal infarct?

What Is Septal Infarct?

A septal infarct refers to an area of tissue damage or necrosis (cell death) that occurs in the septum, which is the wall dividing the chambers of the heart. This condition arises due to inadequate blood supply to the septum, often as a result of a blocked or restricted coronary artery. Understanding septal infarcts, their causes, symptoms, diagnosis, and management is crucial in comprehending their impact on heart health.

Causes And Mechanism

Septal infarcts typically stem from coronary artery disease (CAD), where the coronary arteries, responsible for supplying oxygen-rich blood to the heart muscle, become narrowed or blocked. When a coronary artery is obstructed, the portion of the heart tissue it supplies lacks oxygen and nutrients, leading to cell death or necrosis, resulting in an infarct.


While some individuals may not exhibit noticeable symptoms, others might experience:

  • Chest Pain: Known as angina, chest pain or discomfort might occur due to reduced blood flow to the heart.
  • Shortness of Breath: Difficulty breathing or shortness of breath might arise, especially during physical activity or exertion.
  • Fatigue: Feeling unusually tired or fatigued even with minimal activity.


Diagnostic procedures used to detect septal infarcts and assess their extent include:

  • Electrocardiogram (ECG/EKG): This test records the heart’s electrical activity and can show abnormalities indicative of an infarct.
  • Echocardiogram: Ultrasound imaging of the heart can reveal abnormalities in the heart’s structure and function, helping diagnose a septal infarct.
  • Cardiac MRI or CT Scan: These imaging techniques provide detailed pictures of the heart, aiding in visualization of any damage or abnormalities in the septum.

Treatment And Management

Managing septal infarcts focuses on:

  • Medication: Patients might be prescribed medications to manage symptoms, reduce blood clotting, lower blood pressure, and improve heart function.
  • Revascularization Procedures: In severe cases, procedures such as angioplasty or bypass surgery might be necessary to restore blood flow to the affected area.
  • Lifestyle Changes: Adopting a heart-healthy lifestyle through diet modification, regular exercise, smoking cessation, and stress management plays a crucial role in managing and preventing further heart issues.

Long-Term Outlook

The prognosis for individuals with a septal infarct depends on various factors, including the size of the infarct, overall heart health, and timely intervention. Early detection and appropriate treatment significantly improve outcomes and reduce the risk of further complications.


Septal infarcts, resulting from impaired blood flow to the septum of the heart, pose significant risks to cardiac health. Timely diagnosis, appropriate medical interventions, and lifestyle modifications are key to managing septal infarcts and preventing further complications, underscoring the importance of regular heart health screenings and maintaining a heart-healthy lifestyle.


Is A Septal Infarction Serious?

People with a history of heart trouble may, in some cases, have had a septal infarct. This is a rare but serious kind of heart attack that affects the septum, and can be life threatening. There is no cure for a damaged septum – muscle and tissue separating the heart’s left and right sides.

Why Does My Ekg Say Septal Infarct?

If the finding on an ECG is “septal infarct, age undetermined,” it means that the patient possibly had a heart attack at an undetermined time in the past. A second test is typically taken to confirm the finding, because the results may instead be due to incorrect placement of electrodes on the chest during the exam.

Is A Heart Attack The Same As An Infarct?

Myocardial infarction (MI), colloquially known as “heart attack,” is caused by decreased or complete cessation of blood flow to a portion of the myocardium.

Is An Infarct Serious?

Myocardial infarction (MI) remains the leading cause of death worldwide. [1] Coronary artery disease is a major but preventable cause of morbidity and mortality.
