An enlarged heart may not pump blood effectively, resulting in congestive heart failure. Cardiomegaly may improve over time. But most people with an enlarged heart need lifelong treatment with medications.
When it comes to the heart’s health, there are some things you can’t control -- like getting older, or having a parent with heart disease. But there are many more things you can do to lower the chances of sabotaging your ticker.
“An ounce of prevention really is worth a pound of cure in this instance,” says Gregg Fonarow, MD, an American Heart Association spokesman and associate chief of UCLA's division of cardiology.
To help your heart keep on keeping on, here are 10 things not to do.
The heart enlarges in response to damage to the heart muscle. Up to a point, enlargement permits the heart to continue to pump blood normally. As enlargement progresses, though, the heart's pumping ability declines.
Dilated cardiomyopathy is the main type of cardiomegaly. In dilated cardiomyopathy, the walls of both the left and right side of the heart (ventricles) become thin and stretched. The result is an enlarged heart.
In the other types of enlarged heart, the heart's muscular left ventricle becomes abnormally thick. High blood pressure usually causes left ventricular enlargement (hypertrophy), while hypertrophic cardiomyopathy is an inherited condition.
Generally speaking, the heart's pumping ability is better preserved when the enlarged heart is "thick" rather than "thin."
Causes of an Enlarged Heart
The most common causes of an enlarged heart are blockages in the heart's blood supply (coronary artery disease) and high blood pressure. An enlarged heart can have many other causes, including:
Symptoms vary widely in people with an enlarged heart. Some may never have symptoms. Others may have mild symptoms that remain unchanged for years. And some may experience steadily worsening shortness of breath.
