Pulmonary hypertension and echocardiogram parameters in obstructive sleep apnea
Summary
Pulmonary hypertension (PH) affects 16% of patients with obstructive sleep apnea (OSA). Low oxygen saturation (SpO2) below 70% is a significant risk factor for PH in OSA patients. Routine echocardiograms are recommended.
Area of Science:
- Cardiology
- Pulmonology
- Sleep Medicine
Background:
- Obstructive sleep apnea (OSA) is a growing global health concern linked to obesity and cardiovascular issues.
- Evidence suggests OSA is associated with systemic hypertension, stroke, heart failure, myocardial infarction, and arrhythmias.
- The connection between OSA and pulmonary hypertension (PH) requires further investigation.
Purpose of the Study:
- To determine the prevalence of PH in patients with OSA.
- To identify risk factors for developing PH among OSA patients.
Main Methods:
- Analysis of all OSA patients confirmed by polysomnography in 2015.
- Inclusion of 25 OSA patients in the study.
- Univariate analysis to identify associations between various factors and PH.
Main Results:
- A 16% prevalence of PH was observed in the studied OSA patient cohort.
- Lowest SpO2 <70% showed a statistically significant association with PH (p=0.016).
- No significant associations were found between PH and age, gender, smoking, hypertension, BMI, or apnea-hypopnea index (AHI).
Conclusions:
- The apnea-hypopnea index (AHI) is not a reliable predictor of PH in OSA patients.
- Routine echocardiography is recommended for OSA patients to assess for PH.
- Echocardiogram findings can aid in patient counseling and improve treatment adherence, particularly CPAP usage.

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.

01:21Sleep Apnea
670
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

371
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

1.0K
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...
