Summary
This study found that most patients with arterial hypertension (AH) experience external respiratory function (ERF) disorders and elevated pulmonary pressure. These issues often improve when blood pressure is lowered, indicating a strong link between hypertension, lung function, and circulation.
Area of Science:
- Cardiology
- Pulmonology
- Hypertension Research
Background:
- Arterial hypertension (AH) is a prevalent cardiovascular condition.
- Pulmonary circulatory hemodynamics and external respiratory function (ERF) can be affected by systemic diseases.
- The relationship between early-stage AH and these physiological parameters requires further investigation.
Purpose of the Study:
- To investigate external respiratory function (ERF) in patients with Stages I and II arterial hypertension (AH).
- To assess pulmonary circulatory hemodynamics in patients with early-stage arterial hypertension.
- To determine the impact of elevated blood pressure on ERF and pulmonary pressure.
Main Methods:
- Spirography and echocardiography were performed on 105 patients diagnosed with AH.
- Pulmonary pressure was measured in 43 patients during periods of elevated blood pressure (BP) and under antihypertensive therapy.
- External respiratory function was assessed to identify potential disorders.
Main Results:
- External respiratory function (ERF) disorders were identified in 62.8% of patients with arterial hypertension (AH).
- These ERF disorders demonstrated improvement upon lowering of blood pressure (BP).
- Evidence of elevated pulmonary pressure was observed in the studied patient cohort.
Conclusions:
- Pulmonary hemodynamic disorders, alterations in ERF, and the severity of AH are significantly interconnected in patients.
- Lowering blood pressure may positively impact both ERF and pulmonary hemodynamics in hypertensive individuals.
- These findings highlight the systemic effects of arterial hypertension on respiratory and circulatory systems.

01:18Hypertension and Regulation of Blood Pressure
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
01:30Antihypertensive Drugs: Angiotensin II Receptor Blockers
In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...
01:19Factors 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...

01:21Acute Respiratory Failure-II
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

01:28Hypertension I: Introduction
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
01:29Hypertension II: Pathophysiology
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
