Rheumatic Heart Disease How It Develops

Rheumatic heart disease primarily develops as a result of rheumatic fever, a condition that can occur following an untreated or under-treated streptococcal infection, such as strep throat or scarlet fever. When rheumatic fever occurs, it can cause inflammation and damage to various connective tissues in the body, especially affecting the heart valves. This damage can lead to long-term heart complications, known as rheumatic heart disease.

Understanding the Early Signs

In the early stages of rheumatic fever, symptoms often include joint pain and swelling, commonly referred to as rheumatic arthritis. These symptoms can affect multiple joints and may come and go over time. If not properly managed, the condition can progress and begin to impact the heart, particularly the heart valves, which are crucial for maintaining proper blood flow through the heart.

The Impact on Heart Valves

One of the most common effects of rheumatic fever on the heart is damage to the mitral valve, which can result in a condition called mitral stenosis. Mitral stenosis occurs when the valve opening becomes narrowed, restricting blood flow from the left atrium to the left ventricle. Over time, this can place extra strain on the heart and may eventually lead to heart failure if left untreated.

Environmental and Lifestyle Factors

Interestingly, the incidence of rheumatic heart disease has decreased significantly in recent years, particularly in developed countries. This decline is largely attributed to improved living conditions, better access to healthcare, and more effective treatments for bacterial infections. People who live in overcrowded or unsanitary conditions, especially in colder or more humid climates, are at a higher risk of developing rheumatic fever and subsequently rheumatic heart disease.

Prevention and Management

Preventing rheumatic heart disease starts with early diagnosis and treatment of streptococcal infections using antibiotics. For those who have already experienced rheumatic fever, long-term antibiotic therapy may be recommended to prevent recurrence. Managing heart valve damage often involves regular medical check-ups, medications to support heart function, and in some cases, surgical intervention to repair or replace damaged valves.
