by Lenegres Disease, also known as ligneous myocarditis or fibrous endocarditis, is a rare and progressive condition characterized by the excessive buildup of connective tissue in the heart muscles and valves. This hardening and thickening of heart tissues is called fibrosis and can affect the heart’s ability to pump blood efficiently.
The exact causes of Lenegres Disease are still unknown, but it is believed to involve an abnormal immune response in the body. In a healthy individual, immune cells help fight infection and promote healing. However, in Lev’s disease, immune cells seem to mistakenly attack the heart as if it were foreign, leading to chronic inflammation and overproduction of connective tissue proteins like collagen. Genetics may also play a role, as cases often run in families.
Symptoms
In the early stages, Lev’s disease may produce no noticeable symptoms. As the condition advances, common signs can include:
– Shortness of breath or difficulty breathing with exertion (dyspnea)
– Fatigue
– Chest pain
– Rapid or irregular heartbeat (palpitations or arrhythmias)
– Swelling in the legs, ankles, or abdomen (edema)
– Dizziness or fainting (syncope)
Over time, the thickening and stiffening of heart tissues can lead to severe heart failure if left untreated. Some people may also experience heart murmurs or abnormal heart sounds on examination in later stages.
Diagnosis
If a doctor suspects Lenegres Disease based on symptoms and physical exam findings, several tests can help confirm the diagnosis:
– Electrocardiogram (ECG or EKG): Checks for abnormalities in heart rhythm and electrical conduction.
– Echocardiogram: Uses ultrasound to image the heart walls, valves, and pumping chambers. Allows doctors to view areas of fibrosis.
– Endomyocardial biopsy: A small sample of heart muscle tissue is taken, usually during cardiac catheterization, for analysis under a microscope.
– Cardiac MRI: Provides highly detailed images of the heart muscle and detection of fibrosis.
Stages help determine treatment and prognosis. Advanced cases with substantial scarring have poorer outlooks than early-stage disease with minimal tissue changes. Genetic counseling may be recommended for family members.
Treatment Options
The goals of treatment are to reduce symptoms, prevent further damage to heart tissues, and improve quality of life. Approaches depend on the stage and severity of Lev’s disease:
– Medications: Drugs like ACE inhibitors, beta blockers, and diuretics can help manage heart failure symptoms and modify the body’s immune response in mild to moderate disease.
– Pacemaker or defibrillator: Implanted devices regulate abnormal heart rhythms that can arise.
– Catheter ablation: Destroy heart tissue conducting abnormal electrical signals causing arrhythmias.
– Heart transplant: Considered for younger individuals with severe fibrosis facing the risk of heart failure. While transplanted hearts may also be affected long term.
– Supportive care: Consists of a low-sodium, low-cholesterol diet plus oxygen therapy and activity monitoring as heart function declines.
Prognosis And Outlook
While current treatments cannot reverse established damage or cure Lenegres Disease, they aim to slow progression and provide relief from symptoms. Most patients have a good long-term outlook if diagnosed early before substantial scarring has set in. Later diagnosis accompanies worse prognoses.
With optimal management combining medications, device implantation, and lifestyle changes, many individuals with Lev’s disease live for decades. However, transplantation may become necessary for some facing drug-resistant heart failure. Continued research also works to better understand disease causes, develop targeted therapies, and improve long-term survival in advanced cases.
Complications
Beyond restricting daily activities and work capacity, complications can arise if Lev’s disease goes untreated or proves unresponsive to treatment:
– Heart failure: Stiffened heart tissues fail to adequately pump blood to the body’s organs and tissues over time.
– Life-threatening arrhythmias: Abnormal heart rhythms from electrical conduction defects, especially ventricular tachycardia/fibrillation, increase mortality risk.
– Embolism: Fibrous strands detach and block blood vessels posing stroke/pulmonary embolism risks.
– Pericardial effusion: Fluid buildup around the pericardium sac surrounding the heart compresses it.
– Myocardial calcification: Hard mineral deposits form as fibrosis worsens, increasing strain on the heart.
With diligent medical care and management of modifiable risk factors, many individuals lead full lives for decades. However, Lenegres Disease remains a chronic condition requiring long-term monitoring due to cardiac remodeling and progression likelihood over the years.
