Summary
Resistant hypertension, often linked to conditions like obesity and sleep apnea, requires understanding its complex causes. This review explores the sympathetic nervous system, aldosterone, endothelial dysfunction, and inflammation in resistant hypertension, alongside new treatments.
Area of Science:
- Internal Medicine
- Cardiology
- Nephrology
Background:
- Resistant hypertension is a growing clinical challenge, affecting numerous patients with comorbidities like obesity and sleep apnea.
- Understanding the underlying pathophysiology of resistant hypertension is crucial for effective management.
- The American Heart Association provides diagnostic criteria for resistant hypertension.
Purpose of the Study:
- To review the current understanding of resistant hypertension pathophysiology.
- To explore novel therapeutic targets and ongoing research in resistant hypertension.
Main Methods:
- A narrative review methodology was employed.
- The review focused on four key areas: sympathetic nervous system activity, aldosterone excess, endothelial dysfunction, and inflammation.
- Emerging therapies in resistant hypertension were also examined.
Main Results:
- Resistant hypertension is associated with multiple comorbidities, including obesity, sleep apnea, chronic kidney disease, heart failure, and diabetes mellitus.
- The review highlights the complex interplay of the sympathetic nervous system, renin-angiotensin-aldosterone system, endothelial dysfunction, and inflammation in resistant hypertension.
- Novel therapeutic strategies targeting these pathways are under development.
Conclusions:
- Resistant hypertension is a multifactorial condition requiring a comprehensive approach to management.
- Further research into the pathophysiology of resistant hypertension is essential for developing more effective treatments.
- Emerging therapies hold promise for improving outcomes in patients with resistant hypertension.

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,...

1.9K
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...

2
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,...

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

490
Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...
