Insights

Pulmonary hypertension (PH) is common in young adults. Key risk factors include obesity, physical inactivity, smoking, and diastolic dysfunction, highlighting the need for early intervention.

Area of Science:

  • Cardiology
  • Pulmonology
  • Epidemiology

Background:

  • Pulmonary hypertension (PH) risk factors in young adults are not well understood.
  • This study aimed to identify determinants of PH in this demographic.

Purpose of the Study:

  • To investigate the prevalence and risk factors of pulmonary hypertension in young adults.
  • To identify predictors of elevated pulmonary arterial pressure in a young population.

Main Methods:

  • Analysis of a limited access dataset from the Coronary Artery Risk Development in Young Adults (CARDIA) study.
  • Pulmonary arterial pressure assessed using Doppler pulmonary artery acceleration time (PAAT).
  • Multivariate analysis incorporating socio-demographic, clinical, echocardiographic, pulmonary function, and blood pressure variables.

Main Results:

  • Prevalence of severe PH was 1.1% and mild-to-moderate PH was 14% among 4171 young adults.
  • Significant predictors of PH included higher body mass index, female gender, older age, African American race, lower physical activity, current smoking, larger left atrial dimension, and diastolic dysfunction.
  • Multivariate analysis identified specific associations between these factors and elevated pulmonary arterial pressure.

Conclusions:

  • Pulmonary hypertension is a common finding in young adults, as indicated by echocardiography.
  • Diastolic dysfunction, obesity, physical inactivity, and smoking are significantly associated with increased pulmonary arterial pressure in young adults.
  • Findings underscore the importance of addressing lifestyle and cardiovascular health in preventing PH in younger populations.

Pulmonary Hypertension: Classification and Pathogenesis

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.
There are various classifications for PH, each relating to different underlying causes and also...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme (ECE). Of...
Factors Affecting Pulmonary Ventilation01:19

Factors Affecting Pulmonary Ventilation

Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors

Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
