Rheumatic Heart Disease (RHD) is a chronic heart condition that stems from rheumatic fever—an inflammatory disease that may develop after an untreated or poorly treated group A streptococcal throat infection. RHD primarily affects the heart valves, causing them to become scarred, narrowed, or leaky, which can disrupt normal blood flow and lead to long-term complications. Though preventable, RHD continues to affect millions, especially in low- and middle-income countries, making it a serious public health concern.
At the core of this disease lies the body’s own immune system. When rheumatic fever occurs, the immune response mistakenly attacks the body’s tissues—including the heart valves—thinking they are the same as the streptococcal bacteria. Over time, this immune assault causes permanent damage to the heart valves, primarily the mitral and aortic valves.
RHD may remain asymptomatic for years until significant heart valve damage occurs. When symptoms do manifest, they often include:
Shortness of Breath: This may occur during physical activity or even while at rest in advanced cases.
Fatigue: Due to the heart’s reduced ability to pump blood effectively.
Swelling of the Ankles and Feet: A sign of fluid buildup caused by heart failure.
Palpitations: Irregular heartbeats or a sensation of fluttering in the chest.
Chest Pain: Usually associated with exertion, though not always present.
Fainting or Dizziness: Particularly during activity, as the heart struggles to meet the body’s demands.
These symptoms may mimic other heart-related illnesses, making diagnosis dependent on thorough clinical evaluation and imaging, especially echocardiography.
Rheumatic Heart Disease is largely preventable. The key to prevention lies in the early recognition and proper treatment of strep throat and rheumatic fever. Below are essential precautions:
Prompt Treatment of Sore Throat: Any sore throat, particularly in children aged 5 to 15, should be evaluated by a healthcare provider. If it is caused by a streptococcal infection, a full course of antibiotics (usually penicillin) must be completed to prevent rheumatic fever.
Routine Medical Follow-up: People who have had rheumatic fever need regular follow-up with a healthcare provider to monitor for heart involvement and to receive prophylactic antibiotics, often monthly injections of penicillin, to prevent recurrent rheumatic fever.
Public Awareness and Hygiene: Education on the importance of hygiene, early medical consultation for sore throats, and vaccination strategies can significantly reduce the incidence of streptococcal infections.
Access to Healthcare: Ensuring timely access to primary healthcare facilities, particularly in underserved areas, plays a pivotal role in controlling the progression to RHD.
You should consult a healthcare provider under the following circumstances:
Persistent or Severe Sore Throat: Especially if it is accompanied by fever, swollen lymph nodes, or rash.
Unexplained Fatigue or Shortness of Breath: These may be early signs of heart valve problems.
History of Rheumatic Fever: Regular follow-up is essential, even in the absence of symptoms.
Heart Murmurs or Irregular Heartbeats: These need evaluation through a stethoscope and echocardiography.
Swelling in the Legs or Frequent Fainting: These can be signs of progressing heart disease.
Rheumatic Heart Disease, though preventable, remains a leading cause of cardiovascular morbidity and mortality in certain parts of the world. The key lies in early recognition, timely treatment of streptococcal infections, and sustained medical follow-up for those at risk. Public health initiatives focusing on education, hygiene, and healthcare accessibility can make a significant difference. By staying vigilant to the symptoms and understanding when to seek help, individuals and communities can take meaningful steps toward eradicating this silent yet serious condition.
