Cardiomegaly is the medical term for an enlarged heart. It usually occurs when their is an underlying condition. It may cause problems with the efficacy of pumping the blood, which increases the risk of heart failure or stroke. Enlarged hearts are linked to a family history of cardiomegaly, substance abuse, hypertension and a sedentary lifestyle.

Cardiomegaly is cared for by managing the conditions that cause the heart to thicken or dilate. Depending on the cause, cardiomegaly can be either temporary or permanent. Although sometimes asymptomatic, cardiomegaly is generally associated with several symptoms.1‘Enlarged Heart (Cardiomegaly): Causes, Symptoms, Treatment.’ Cleveland Clinic, my.clevelandclinic.org/health/diseases/21490-enlarged-heart-cardiomegaly


Fainting can be a symptom of an enlarged heart. The medical term for fainting is syncope. It is caused when there's a temporary drop in the blood flow to the brain. Blood pressure is most likely to drop in people with cardiomegaly when they change positions, for instance, going from standing to lying down. When blood pressure drops, it can affect blood flow through the body and cause a person to pass out.

When someone faints, they will likely become conscious right away. Confusion may continue to linger for a few moments.2‘Syncope: Symptoms, Causes, Treatments.’ Cleveland Clinic, my.clevelandclinic.org/health/diseases/17536-syncope
