Resumen

El microembolismo durante las intervenciones coronarias percutáneas (PCI) está relacionado con la mionecrosis. La ecografía Doppler intracoronaria muestra una mayor frecuencia de microembolías en pacientes con infarto de miocardio periprocedural, lo que confirma la microembolización como causa.

Área de la Ciencia:

Medicina Cardiovascular La medicina cardiovascular es una especialidad de la salud.
Cardiología Intervencionista Cardiología intervencionista.
Ecografía de diagnóstico por ultrasonido.

Sus antecedentes:

Los cables guía Doppler intracoronarios permiten la detección en tiempo real de microembolismo durante las intervenciones coronarias percutáneas (PCI).
Investigó la relación entre la frecuencia de microembolismo detectado por Doppler y la incidencia de mionecrosis durante la ICP electiva.

Objetivo del estudio:

Para determinar si la frecuencia de microembolismo detectado por Doppler intracoronario durante la ICP se correlaciona con la ocurrencia de infarto de miocardio periprocedural (IMP).
Evaluar el impacto del microembolismo en la inflamación sistémica y la función microvascular después de la ICP.

Principales métodos:

Comparación de la frecuencia de microembolismo utilizando ultrasonido Doppler intracoronario en pacientes con y sin IMP sometidos a ICP electiva.
Se analizaron las características clínicas y de procedimiento, los niveles de proteína C reactiva de alta sensibilidad y la elevación de la troponina I cardíaca.

Principales resultados:

Los pacientes con IMP exhibieron un número total significativamente mayor de microembolías coronarias después de la ICP en comparación con aquellos sin IMP (27±10 vs. 16±8, P<0.001).
Los niveles de proteína C reactiva de alta sensibilidad después de la ICP fueron elevados en el grupo de IMP (12,6±10,4 frente a 6,1±5,1 mg/L, P<0,05).
El recuento microembólico se correlaciona con la elevación de la troponina I, la reserva de velocidad de flujo coronario y la velocidad máxima promedio de referencia.

Conclusiones:

Una mayor frecuencia de microembolización coronaria durante la ICP está significativamente asociada con la IMP.
La microembolización contribuye a la respuesta inflamatoria sistémica y al deterioro microvascular observado después de la ICP.
La ecografía Doppler intracoronaria confirma la microembolización como la causa de la IMP en pacientes sometidos a ICP electiva.

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Glomerular Filtration

Glomerular Filtration

The filtration membrane in the renal system is a highly specialized structure essential for filtering blood. It consists of glomerular capillaries and podocytes, forming a selective barrier that permits the passage of water and small solutes while restricting most plasma proteins and blood cells.
Components of the Filtration Membrane
The filtration process involves three key layers: the glomerular endothelial cells, the basement membrane, and the podocyte-formed filtration slits.

Renal Corpuscle

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Nephrons

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Glomerular Filtration Rate and its Regulation

Glomerular Filtration Rate and its Regulation

The Glomerular Filtration Rate (GFR) is a measure of kidney function, reflecting the volume of filtrate formed per minute in the kidneys. On average, GFR is approximately 125 mL/min in males and 105 mL/min in females. Maintaining a relatively constant GFR is essential for the kidneys to effectively regulate body fluid homeostasis and maintain extracellular stability.
GFR regulation involves two primary intrinsic controls: the myogenic and tubuloglomerular feedback mechanisms.
The myogenic...
