Heart Attack in the Septum: Causes, Signs, and Identification Methods

A septal infarct, a type of heart attack, occurs when the blood supply to the interventricular septum—the muscular wall dividing the left and right sides of the heart—is blocked. This condition often results from a myocardial infarction (heart attack).

Symptoms of Septal Infarct

Symptoms of a septal infarct are similar to those of an acute myocardial infarction and may include persistent or worsening chest pain, shortness of breath, cold sweats, nausea, fatigue, and atypical pain such as jaw, back, or arm pain, especially in women. In severe cases, a distinctive finding may be a holosystolic murmur along the left sternal border due to ventricular septal rupture.

Diagnosis and Treatment

An electrocardiogram (ECG) is often the first test used to check for a septal infarct, measuring the heart's electrical activity to help spot cardiac abnormalities. However, EKG results can sometimes be misleading, and doctors may order additional tests such as an echocardiogram, cardiac MRI, or nuclear stress test to confirm the diagnosis.

Treatment for septal infarct involves urgent reperfusion, medical stabilization, and possibly surgical repair for mechanical complications. Reperfusion therapy may include primary percutaneous coronary intervention (PCI) or thrombolytics to re-open blocked coronary arteries. Supportive therapy includes medications managing heart failure symptoms, arrhythmias, and hemodynamic instability. Long-term management involves lifestyle modifications, beta-blockers, antiplatelet agents, and statins to reduce future cardiovascular events.

Outlook and Prevention

The outlook for septal infarct depends on various factors, including the extent of damage to the heart, the location of the septal infarct, the person's overall health and wellness, and the presence of ventricular septal rupture (VSR). In cases of VSR, the outlook depends on the size of the tear and how quickly the person receives medical attention.

Preventing heart attacks and, consequently, septal infarcts, involves managing risk factors such as high blood pressure, unhealthy cholesterol levels, diabetes, obesity, lack of physical activity, smoking and other nicotine use, excessive alcohol intake, diet high in saturated fats, trans fats, cholesterol, and sodium. Recognizing variations in heart attack symptoms is crucial for early detection and timely medical intervention.

In conclusion, prompt recognition and treatment of septal infarct are essential to improve outcomes. If you experience any symptoms suggestive of a heart attack, seek immediate medical attention. Living a heart-healthy lifestyle can help reduce the risk of cardiovascular disease and heart attacks.
