Pulmonary hypertension how is it diagnosed




















There is limited evidence to support screening of asymptomatic individuals. Echocardiography is recommended as the initial step in the evaluation of patients with suspected pulmonary hypertension. A definitive diagnosis cannot be made on echocardiographic abnormalities alone, and some patients require invasive evaluation by right heart catheterization. For certain categories of pulmonary hypertension, particularly pulmonary arterial hypertension, treatment options are rapidly evolving, and early diagnosis and prompt referral to an expert center are critical to ensure the best prognosis.

There are no directed therapies for many other categories of pulmonary hypertension; therefore, family physicians have a central role in managing contributing comorbidities. Other important considerations for patients with pulmonary hypertension include influenza and pneumonia immunizations, contraception counseling, preoperative assessment, and mental health.

Pulmonary hypertension is a heterogeneous group of disorders characterized by a mean pulmonary arterial pressure of 25 mm Hg or greater at rest during right heart catheterization.

In , the classification scheme was updated to recognize five groups of pulmonary hypertension 6 Table 1 3 , 4 , 6. Enlarge Print. Echocardiography is the recommended initial test in the evaluation of patients with suspected pulmonary hypertension.

Results from invasive hemodynamic testing with right heart catheterization, preferably at an expert center, should be obtained before initiating treatment with vasodilator therapy in patients with pulmonary arterial hypertension. In patients with pulmonary hypertension due to lung disease or left heart disease, treatment should focus on optimizing comorbid conditions.

Use of vasodilator therapies in patients with pulmonary hypertension due to lung disease or left heart disease is potentially harmful and not recommended. Patients with chronic thromboembolic pulmonary hypertension should receive lifelong anticoagulation in the absence of contraindications. Patients with pulmonary hypertension should receive seasonal influenza vaccination and age-appropriate pneumococcal vaccination, unless contraindicated.

Perioperative assessment of patients with pulmonary hypertension should include echocardiographic assessment of right ventricular function.

Including idiopathic, heritable, and HIV-associated; systemic sclerosis and other connective tissue disease; congenital heart disease; schistosomiasis; drug- and toxin-induced. Group 2: Pulmonary hypertension due to left heart disease. Including chronic obstructive pulmonary disease, sleep-disordered breathing, and interstitial lung disease. Group 4: Chronic thromboembolic pulmonary hypertension.

Including metabolic, systemic, and hematologic disorders sickle cell disease , and others. Information from references 3 , 4 , and 6. Although pulmonary arterial hypertension group 1 has benefited the most from progress with targeted therapy, this diagnosis is rare and may not be encountered by many family physicians. The American College of Chest Physicians published treatment guidelines in Family physicians most often encounter pulmonary hypertension in patients with chronic disease such as heart failure, obstructive lung disease, and thromboembolism.

Pulmonary hypertension is most prevalent in those with left heart disease group 2. There is limited evidence to guide screening for pulmonary hypertension in asymptomatic individuals, even in high-risk groups, which leads to significant delays in diagnosis. This likely reflects the challenges of diagnosis in patients with comorbidities. Independent of classification, pulmonary hypertension can cause progressive, disabling symptoms, as well as increases in morbidity and mortality. For example, pulmonary hypertension status in patients who also have COPD may be more predictive of mortality than pulmonary function markers, such as forced expiratory volume in one second or diffusing capacity.

The mechanisms that increase pulmonary pressures can act primarily on the pulmonary arterial bed or venous bed, either alone or in combination. Regardless of the mechanism, persistently increased pulmonary arterial pressure strains the thin-walled right ventricle.

Adapted to the low-pressure pulmonary circulation, the right ventricle is unable to sustain cardiac output with these pressures. There are no data to support screening of asymptomatic individuals for pulmonary hypertension, even in high-risk groups such as those with a family history of pulmonary arterial hypertension without known BMPR2 mutations.

Recognizing pulmonary hypertension in patients presenting with new signs or symptoms can be difficult because many symptoms are common and associated with an extensive differential diagnosis Table 2 1 — 3 , Pulmonary hypertension should be considered in patients with chronic illness and symptoms that are disproportionate to the underlying disease or poorly responsive to treatment.

Abnormal pulse oximetry, elevated jugular venous pressure, ascites, lower extremity edema, right ventricular heave, tricuspid regurgitation murmur increased pulmonic component of S2. Electrocardiography: right ventricular enlargement, right bundle branch block, right ventricular strain pattern, S1Q3T3 pattern.

Information from references 1 through 3 , and A stepwise approach can minimize the risks and costs of unnecessary testing Figure 1. Physicians should initially consider the history, clinical findings, and targeted noninvasive testing, particularly echocardiography.

Patients presenting with signs of advanced pulmonary hypertension right heart failure or syncope should be promptly evaluated with echocardiography. Some patients require right heart catheterization, which is important for classification and subsequent treatment options.

For example, those with mildly increased systolic pulmonary arterial pressure i. Suggested algorithm for the evaluation of suspected pulmonary hypertension in primary care. Echocardiography is the initial noninvasive diagnostic test, according to national guidelines.

In the early stages of PAH, you may not notice any symptoms at all. As the disease progresses, you will start to experience symptoms common to other lung diseases, such as asthma , emphysema or chronic obstructive pulmonary disease COPD. The most common symptoms of PAH are:.

Because symptoms are similar to other common lung diseases, it can often be hard to diagnose PAH. Diagnosis is a process of eliminating other diseases. With the help of lung and heart specialists pulmonologist and cardiologist you will need to take a number of tests, such as:.

After reading our Pulmonary Hypertension Health Topic, you may be interested in additional information found in the following resources. Pulmonary Hypertension. Also known as pulmonary arterial hypertension PAH. Pulmonary hypertension occurs when the pressure in the blood vessels that carry blood from your heart to your lungs is higher than normal. One type of pulmonary hypertension is pulmonary arterial hypertension PAH. Pulmonary hypertension can happen on its own or be caused by another disease or condition.

In the United States, the most common cause of pulmonary hypertension is left heart disease. Other conditions that can cause pulmonary hypertension include sickle cell disease; pulmonary embolus, which is a type of venous thromboembolism; and chronic obstructive pulmonary disease COPD. The increased pressure in the blood vessels of the lungs means that your heart has to work harder to pump blood into the lungs.

This can cause symptoms such as shortness of breath, chest pain, and lightheadedness. If left untreated, the increased pressure can damage your heart. This may lead to serious or life-threatening complications, such as heart failure or arrhythmias, which are irregular heart rhythms. Explore this Health Topic to learn more about pulmonary hypertension, our role in research and clinical trials to improve health, and where to find more information.
