If you suspect that you have carcinoid heart disease, you may be wondering what causes the condition. This article will discuss the symptoms and treatment options for this disease. It will also discuss the mortality rate for those diagnosed with it. In addition, you will learn how to recognize the warning signs and symptoms of this condition. The main symptoms of carcinoid heart disease are:
Diagnosis
Carcinoid heart disease is a common complication in patients with carcinoid syndrome, and it is responsible for a substantial amount of morbidity and mortality. Although the pathophysiology of the disease is unclear, chronic exposure to high concentrations of circulating serotonin is thought to be a key contributor. Despite this, international consensus guidelines for screening and diagnosis of carcinoid heart disease are lacking. Nevertheless, there are a number of diagnostic tests available that may be helpful in the diagnosis of this condition.
The clinical symptoms of carcinoid heart disease typically present between the fifth and seventh decades of life, and they typically appear between 55 and 60 years of age. There is a considerable lag between the onset of symptoms and the diagnosis, typically between 24 and 28 months to five years. Depending on the severity of valvar disease and cardiac symptoms, the diagnosis may take longer to reach. Patients with carcinoid syndrome may also experience other symptoms, such as diarrhoea and bronchospasm.
An MRI of the heart is the most reliable diagnostic test for carcinoid heart disease. A cardiac scan can reveal multiple tumors in the heart, including those that have spread from the liver. It is also helpful to perform an echocardiography to determine the stage and extent of the disease. Patients who develop symptoms of carcinoid heart disease should be evaluated by a cardiac surgeon. Once diagnosed, the treatment plan must be tailored to the patient’s specific needs and lifestyle.
The study compared the survival rates of patients treated from 1980 to 1990. Surgical procedures such as thoracoabdominal computed tomography or radiotherapy have changed the outlook for patients with carcinoid heart disease.
The median survival time for patients with carcinoid heart disease was 4.8 years, ranging from 3.8 to 5.7 years. Early postoperative mortality rate was 16% (95% CI, 8% to 24%) for group A patients, 22% (7 patients in group B, and 9% (4 patients in group C). Interestingly, the 5-HIAA serum level was higher in patients who died within the first 30 days.
The biochemical burden of carcinoid heart disease predicts the rate of progression and death. Treatment of carcinoid heart disease aims to reduce the amount of vasoactive substances secreted by the tumour and reduce its burden on the heart. Some treatments are also effective in preventing the progression of the disease, such as treatment with anti-inflammatory drugs or hepatic resection.
Treatment
The survival rate for carcinoid heart disease is variable, ranging from less than one year to more than four years. Most data come from patients treated between 1980 and 1990, when somatostatin analogues, hepatic artery dearterialization, and heart valve replacement became common. This study sought to determine the prognosis of patients with metastatic carcinoid disease and echocardiography evidence of carcinoid heart disease.
Surgical intervention can help reduce bleeding and eliminate symptoms of carcinoid heart disease. An FDA-approved drug called telotristat ethyl (Xermelo) may change the progression of the disease. A study published in the Journal of the American College of Cardiology found that patients receiving telotristat ethyl had a significantly lower risk of death and more favorable cardiac outcomes.

Although a significant proportion of patients died during the follow-up period, the median survival for patients with carcinoid heart disease was approximately five years after diagnosis. In patients who had advanced metastatic carcinoid disease, the survival rate was significantly lower in group B than in group C. However, patients in group A had higher median 5-HIAA serum levels than those in group B or C. For patients with advanced carcinoid heart disease, the most effective treatment may be cardiac surgery or palliative treatment.
Patients with carcinoid heart disease may have labile blood pressure and pronounced hypertension. The blood pressure is dependent on the relative quantities of vasoactive substances present in the patient’s blood, and a low level of serotonin can cause a hypertensive crisis. Transthoracic echocardiography may be used to measure urinary excretion of 5-hydroxyindole acetic acid.
The diagnosis of carcinoid heart disease is based on the presence of elevated biomarkers. Imaging modalities such as an echocardiogram are the gold standard. Because carcinoid heart disease is characterized by cardiac dysfunction and tumor burden, treatment is often difficult and prolonged. Watchful waiting is an effective therapy in early stages of the disease. Surgical procedures for the replacement of cardiac valves are also used to control seroton secretion from the NET.
Patients with carcinoid heart disease may have anemia or other symptoms that are non-hormonal. Some may experience abdominal pain, anemia, bronchoconstriction, and hypotension. In some patients, carcinoid heart disease may not produce any symptoms at all. However, doctors should monitor the patient’s condition closely and seek the appropriate treatment if they experience any of these symptoms. In the case of severe carcinoid heart disease, it is best to consult a physician to receive the proper diagnosis and treatment.
In the first stage, patients with high levels of brain natriuretic peptide (BNP) may be considered to have carcinoid heart disease. This test may be used to screen asymptomatic patients. If a patient has a high clinical suspicion, an echocardiogram is the diagnostic test of choice. The echocardiographic appearance of the valves is pathognomonic and quantification of valvular dysfunction is helpful. Additionally, cardiac magnetic resonance imaging or computerized tomography can provide additional clinical information in select patients.
Mortality
Mortality due to carcinoid heart is highly variable, but factors that predict mortality include the severity of the disease, right ventricular size, and NYHA class. The mortality rate is higher in women and men, but the study’s primary end point was overall mortality due to any cause. Despite its rarity, mortality due to carcinoid heart disease is a significant contributor to the overall cardiovascular morbidity and mortality.
Survival of patients with a first-stage diagnosis of carcinoid heart disease has improved considerably over the past two decades. Surgical intervention for valve replacement has improved long-term outcomes, and the introduction of surgery has improved prognoses. These improvements may be due to the introduction of surgical intervention for the treatment of carcinoid heart disease. Drs. Moller and Bernheim acknowledge that they received grants from the Danish Heart Foundation and the Swiss National Science Foundation to conduct their study.
One study has looked at the mortality rates of 66 patients with this disease from July 1989 to May 1995 and June 1995 to 2000. Researchers reviewed their medical charts and looked for changes in the NYHA class at the time of their first carcinoid heart disease diagnosis and immediately prior to cardiac surgery. Additionally, they noted that two patients were taking serotonin reuptake inhibitors and one was taking an ergot alkaloid.
To improve survival, doctors should seek medical treatment from a multidisciplinary team, including a surgeon with extensive experience in treating carcinoid heart disease. This multidisciplinary team should perform an appropriate diagnostic study and plan a surgical treatment that addresses the underlying causes of carcinoid heart disease. Surgical treatment can improve the patient’s quality of life, but the decision on the right valve prosthesis depends on the patient’s risk for bleeding and other therapeutic interventions.
In a study of 200 carcinoid heart disease patients over two decades, more than half underwent surgical valve replacement. In another study, Castillo JG and Rahmanian PB looked at the early and late results of valvular surgery. In a third study, Edwards NC and colleagues looked at the effect of valvular surgery on carcinoid heart disease. These results also included observational cohort studies.
The treatment for carcinoid heart disease is complex, but has shown promising results. Cardiovascular surgery and somatostatin analogues can prevent or reduce the development of the disease. Despite its serious consequences, the prognosis is still excellent. With more advances in medical technology, treatment options for carcinoid heart disease are improving. The treatment for this disease is multidisciplinary and involves medical and surgical intervention.

In some patients, elevated levels of brain natriuretic peptide (BNP) may raise clinical suspicion of carcinoid heart disease. Nonetheless, no definitive diagnosis of the disease is possible without further testing. In cases where the disease is advanced, surgical intervention may improve the prognosis and improve the quality of life. Insufficient evidence supports a universal screening strategy, but limited studies have demonstrated a positive correlation between early surgery and reduced mortality.
