Summary
Hypertension and atrial fibrillation are common in hemodialysis patients. Increasing age is a risk factor for atrial fibrillation, while female sex is a risk factor for hypertension in this population.
Area of Science:
- Nephrology
- Cardiology
- Epidemiology
Background:
- Hypertension (HTN) and atrial fibrillation (AF) are prevalent comorbidities in patients undergoing hemodialysis (HD).
- Understanding the associations and risk factors for HTN and AF in HD patients is crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the prevalence of hypertension and atrial fibrillation in hemodialysis patients.
- To investigate the association between hypertension and atrial fibrillation in this cohort.
- To identify risk factors for the development of HTN and AF in HD patients.
Main Methods:
- A cross-sectional study utilizing chart review of 304 hemodialysis patients with at least 6 months of HD treatment.
- Data collected included demographics, hemodynamics, laboratory values, blood pressure before and after dialysis, and presence of AF.
- Statistical analysis included odds ratios and confidence intervals to assess risk factors.
Main Results:
- The prevalence of AF was 20% (n=68), with an increased risk associated with advancing age (OR: 1.04).
- Hypertension was highly prevalent (66.45%, n=202), with increasing comorbidity scores linked to higher HTN risk (OR: 2.47).
- Key risk factors identified were increasing age for AF and female sex for HTN. HTN and diabetes significantly increased AF risk post-HD.
Conclusions:
- Hypertension and atrial fibrillation are significant concerns in the hemodialysis population.
- Age is a primary risk factor for AF, while female sex contributes to HTN risk in HD patients.
- Concurrent HTN and diabetes markedly elevate the risk of developing AF after hemodialysis, necessitating targeted interventions.

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,...

431
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

2.1K
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...

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

731
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...
