Risk factors detection in chronic thromboembolic pulmonary hypertension, a tool for risk quantification?
Bratislavske Lekarske Listy
|November 10, 2016
Summary
This study confirms known risk factors for chronic thromboembolic pulmonary hypertension (CTEPH) and identifies platelet abnormalities as potential new markers. The prevalence of CTEPH is estimated at 1.8 per 100,000 adults.
Area of Science:
- Pulmonary Hypertension Research
- Hematology
- Epidemiology
Background:
- Chronic thromboembolic pulmonary hypertension (CTEPH) involves pulmonary artery obstruction.
- The exact causes of CTEPH are not fully understood, but several risk factors are known.
- Identifying new risk factors and understanding prevalence are crucial for managing CTEPH.
Purpose of the Study:
- To assess the risk profile and factor representativeness in CTEPH patients.
- To explore potential novel risk factors for CTEPH.
- To determine the epidemiological prevalence of CTEPH in the studied country.
Main Methods:
- Analysis of established CTEPH risk factors in 81 patients.
- Detailed examination of hematological parameters in a specialized laboratory.
- Comparison of CTEPH patients with healthy control groups.
Main Results:
- Confirmed risk factors include pulmonary embolism (PE), deep vein thrombosis (DVT), thyreopathy, non-O blood types, inflammatory bowel disease, malignancy, splenectomy, and pacemakers.
- Observed significant hematological differences: decreased platelet count, increased mean platelet volume, higher spontaneous platelet aggregation, and elevated von Willebrand factor and fibrinogen.
- Median representativeness of risk factors was 3 (PE, DVT, non-O blood type).
- Estimated CTEPH prevalence at 1.8 per 100,000 adults.
Conclusions:
- Established CTEPH risk factors were confirmed, and their representativeness quantified.
- Platelet abnormalities were identified as potential new risk markers for CTEPH.
- The prevalence of CTEPH in the adult population was determined.

1.1K
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...

760
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.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
4.0K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
