Right Ventricular Hypertrophy: Causes, Risks, and Why Athletes Need Screenings

Right ventricular hypertrophy (RVH) is a condition where the muscle on the right side of the heart thickens and enlarges. This change often happens due to problems in the lungs or heart, leading to increased blood pressure and potential complications if untreated. Doctors frequently check for RVH in young athletes before they join sports teams to prevent undetected risks. RVH typically develops when lung conditions, such as pulmonary arterial hypertension, force the heart to work harder. Other causes include heart failure, chronic obstructive pulmonary disease (COPD), or blockages like pulmonary embolism. Structural heart issues, such as an atrial septal defect or pulmonary valve stenosis, can also trigger the condition.

The thickening of the heart muscle raises blood pressure and disrupts electrical signals, which can lead to serious health problems. Common symptoms include chest pain, dizziness, fainting, shortness of breath, and swelling in the legs or ankles. Diagnosing RVH usually involves tests like a chest X-ray, electrocardiogram (EKG), or echocardiogram. Treatment varies depending on the underlying cause and may include medication, a pacemaker, or surgery. Lifestyle changes, such as reducing salt intake, quitting smoking, maintaining a healthy weight, and limiting alcohol, can help lower the risk of complications.

Without proper treatment, RVH can raise the risk of congestive heart failure or cardiac arrest. Early detection through screenings, especially for athletes, remains crucial. Managing the condition often requires addressing its root cause while adopting healthier habits to protect heart function.
