The structural integrity of your heart determines its ability to sustain life
In short: A healthy heart is remarkably robust, but structural abnormalities can disrupt its essential rhythm. Whether born with these issues or acquiring them through age, infections, or environmental factors, structural heart disease compromises the very mechanics required to deliver oxygen and nutrients to your cells.
Structural heart disease is a broad classification encompassing abnormalities in the heart's valves, walls, chambers, or muscles. These conditions are generally divided into three main categories: congenital heart disease, which is present at birth; cardiomyopathy, which involves the heart muscle; and heart valve disease. Valve disease is the most prevalent form, occurring when one of the four valves—the mitral, tricuspid, pulmonary, or aortic—fails to function correctly. This failure typically manifests in two ways: regurgitation, where the valve leaks and allows blood to flow backward, or stenosis, where the valve narrows and restricts blood flow.
The physiological consequences of these malfunctions can be severe. When a valve becomes stenotic, the heart must contract with increased force to push blood through the narrowed opening. Conversely, regurgitation can lead to volume overload within the heart chambers. If the heart cannot pump sufficient blood to meet the body's needs, it may result in heart failure or even death if left untreated. This dysfunction can eventually damage other organs and tissues due to the lack of oxygen and nutrients being delivered to cells.
Risk factors vary depending on the specific condition. For congenital issues, maternal exposure to certain factors during pregnancy—such as rubella, industrial solvents, alcohol, or certain medications—can increase the risk for the child. For acquired diseases, factors like viral infections, drugs, or coronary artery disease may affect the muscle and linings. While these conditions can affect anyone regardless of sex or ethnicity, the risk increases significantly with age; for instance, more than 10% of adults over the age of 75 live with structural heart disease.
