Resumen

Los corredores de maratón aficionados muestran una interacción cardiovascular deteriorada con un índice de rigidez auricular izquierdo más alto y relaciones PWV / GLS. La distancia semanal de carrera predice estos cambios, lo que indica un posible riesgo cardiovascular.

Área de la Ciencia:

Cardiología Cardiología.
Medicina del Deporte Medicina del Deporte Medicina de los Deportes
La ecocardiografía es una ecocardiografía.

Sus antecedentes:

El ejercicio prolongado de resistencia de alta intensidad puede conducir a la remodelación estructural del miocardio.
Comprender la interacción cardiovascular integrada es crucial para evaluar el riesgo cardiovascular en los atletas.

Objetivo del estudio:

Para investigar el acoplamiento left atrial-left ventricular-arterial (LA-LV-arterial) en corredores de maratón aficionados.
Para evaluar la adaptación estructural cardíaca y la rigidez arterial utilizando 3D-STE.
Para identificar los predictores de riesgo cardiovascular en esta población.

Principales métodos:

Se inscribieron 93 corredores de maratón aficionados (ultramaratón y maratón clásico) y 40 controles.
La ecocardiografía convencional y el 3D-STE se utilizaron para evaluar el volumen y la función de LA, y la cepa LV.
Se analizaron las correlaciones entre el índice de rigidez auricular izquierda (LASI), la relación PWV / GLS y los parámetros de funcionamiento.

Principales resultados:

Los corredores de maratón (grupos UM y M) tenían ratios significativamente más altos de LASI y PWV / GLS en comparación con los controles.
Ambos grupos mostraron un aumento de los volúmenes auriculares izquierdos (LAV) en comparación con los controles, con los ultramaratonistas mostrando valores mayores.
La distancia de carrera semanal fue un predictor independiente del acoplamiento LA-LV-arterial.

Conclusiones:

Los corredores de maratón aficionados muestran deterioro de la estructura y función de la AL después de un ejercicio prolongado.
Las elevadas proporciones de LASI y PWV/GLS son indicadores tempranos de acoplamiento anormal LA-LV-arterial.
3D-STE es sensible en la detección de alteraciones subclínicas, ayudando en la evaluación de la interacción cardiovascular.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

G-protein Coupled Receptors

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.
