Introduction:

Pulmonary capillary wedge pressure (PCWP) and right atrial pressure (RAP) are key haemodynamic indicators of cardiac congestion. Atrial fibrillation (AF) often coexists with several heart diseases, making it challenging to determine AF's independent contribution to atrial pressure elevation. Therefore, the impact of AF on PCWP and RAP requires clarification. We sought to quantify the contribution of AF on PCWP and RAP within patients with various chronic heart diseases.

Methods:

We performed a single-center retrospective analysis on 1452 patients (age: 68.0 ± 13.6 years, 58.7% male, 26% AF) with chronic heart diseases undergoing right heart catheterization (RHC). PCWP and RAP were measured during RHC, and the underlying AF or sinus rhythm (SR) was annotated. To isolate AF effect from clinical, haemodynamic, and echocardiographic confounders, two propensity score matching analyses yielded two balanced cohorts for PCWP (n = 496) and RAP (n = 494) analysis.

Results:

After matching, PCWP was higher in the AF than the SR group (18.4 ± 0.49 mmHg vs 15.7 ± 0.49 mmHg; P < .001). Similarly, RAP was higher in the AF than the SR group (8.7 ± 0.34 mmHg vs 7.5 ± 0.34 mmHg; P = .02). The findings were highly robust for PCWP (E-value = 10.8) and moderately robust for RAP (E-value = 2.78) to unmeasured confounders. Additionally, patients in the SR cohort with a prior history of AF had significantly higher PCWP and RAP compared to patients with no AF history.

Conclusion:

In our cohort, AF increased PCWP by 2.6 mmHg and RAP by 1.1 mmHg. Furthermore, a previous history of AF is linked to higher atrial pressures in patients later in SR.

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Mitral Regurgitation I: Introduction

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Mitral Stenosis I: Introduction

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...
