Rheumatic heart disease: What you need to know

Rheumatic heart disease (RHD) is a serious condition that can occur after an episode of rheumatic fever, an inflammatory disease itself usually triggered by a Streptococcus bacterial infection, such as strep throat or scarlet fever.

This heart disease is a chronic condition that affects the heart valves, causing them to become damaged or scarred. It can lead to heart failure, stroke, and other life-threatening complications if not managed properly.

This article aims to shed light on the risk factors, symptoms, treatments, and more regarding RHD, presenting the information in an accessible way for everyone.

First, let’s delve into the risk factors. Rheumatic fever, the precursor to RHD, is more common in children and young adults, typically between the ages of 5 and 15, and its transition to RHD can be influenced by several factors.

These include inadequate or delayed treatment of strep throat infections, living in overcrowded conditions, poor sanitation, and lack of access to healthcare—conditions that are unfortunately more prevalent in low- and middle-income countries.

Genetic predisposition also plays a role, with some individuals being more susceptible to developing RHD following rheumatic fever than others.

Symptoms of RHD vary depending on the severity and the specific heart valves affected. In the early stages, symptoms might be mild or even non-existent.

As the condition progresses, symptoms can become more pronounced and may include shortness of breath, fatigue, chest pain, swelling of the feet or ankles (edema), and a fluttering or thumping in the chest (palpitations).

Because RHD primarily affects the heart valves, it can lead to complications such as atrial fibrillation (an irregular heart rhythm), heart failure, and stroke.

The cornerstone of treating RHD involves managing the symptoms and preventing further damage to the heart. Antibiotics are used to treat strep throat infections promptly to prevent rheumatic fever from occurring in the first place.

For those who have already developed RHD, antibiotics, anti-inflammatory medications, and medications to manage heart failure and arrhythmias may be prescribed. In severe cases, surgery might be necessary to repair or replace damaged heart valves.

Prevention plays a crucial role in addressing RHD. This includes improving access to medical care, promoting better hygiene to prevent strep throat infections, and providing antibiotics to those who have had rheumatic fever to prevent recurrences, which can worsen heart damage.

Vaccines against Streptococcus bacteria are also under investigation and could provide a significant breakthrough in preventing both rheumatic fever and RHD.

Research into RHD continues, with studies focusing on better understanding the disease’s pathogenesis, improving diagnostic methods, and developing more effective treatments.

One area of interest is the development of vaccines that could prevent Streptococcus infections, thereby reducing the incidence of rheumatic fever and RHD.

Additionally, efforts are being made to improve healthcare access and education in regions where RHD is most prevalent, aiming to reduce the disease’s impact.

In conclusion, rheumatic heart disease is a condition with significant health implications, particularly in parts of the world with limited access to healthcare.

Understanding the risk factors and symptoms is crucial for early detection and treatment, which can significantly improve outcomes for those affected.

Ongoing research and preventive measures are key to combating this disease, with the hope of eventually eradicating it altogether.

Through a combination of medical treatment, preventive strategies, and global health initiatives, there is hope for reducing the burden of RHD and improving the lives of those affected by this preventable disease.
