Summary
Atrial fibrillation (AF) is common in heart failure (HF) patients, particularly those with preserved ejection fraction. While AF was linked to lower quality of life, its association with mortality in HF was not statistically significant after adjusting for age.
Area of Science:
- Cardiology
- Clinical Research
- Epidemiology
Background:
- Heart failure (HF) and atrial fibrillation (AF) frequently coexist, but their combined impact in Latin America remains understudied.
- This study investigated the characteristics and outcomes of HF patients with AF in Colombia.
Purpose of the Study:
- To characterize the sociodemographic and clinical features of HF patients with AF.
- To evaluate the outcomes, including mortality, associated with AF in a Colombian HF cohort.
Main Methods:
- Analysis of data from the Colombian Heart Failure Registry (RECOLFACA).
- Inclusion of ambulatory HF patients with persistent or permanent AF.
- 6-month follow-up with all-cause mortality as the primary outcome.
- Logistic regression was used to assess the impact of AF on mortality.
Main Results:
- Of 2,514 HF patients with AF data, 22.3% had AF. AF patients were older (73 vs. 66 years) and had distinct comorbidity and device profiles.
- AF was associated with a lower quality of life (EuroQol-5D) and was more prevalent in patients with preserved ejection fraction (EF).
- Unadjusted mortality was higher in the AF group (8.9% vs. 6.1%), but this association lost statistical significance after multivariate adjustment for age (OR: 1.35; 95% CI: 0.95 - 1.92).
Conclusions:
- Atrial fibrillation is more prevalent in HF patients with higher EF, reduced quality of life, and different clinical profiles.
- HF severity and the association with mortality were not independently significant in this cohort.
- Further research is needed to better understand the implications of coexisting AF and HF.

01:17Pathophysiology of Heart Failure
1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

01:26Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
429
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...

01:22Heart Failure Drugs: β-Blockers
338
β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

01:28Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...

01:22Heart Failure Drugs: Diuretics
375
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...

01:26Heart Failure Drugs: Inotropic Agents
586
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
