Resumen
Un nuevo método, el espesor ponderado total de la placa (wTPT), predice mejor el riesgo cardiovascular al cuantificar la carga de placa de la aterosclerosis. La carga de la placa femoral, medida por wTPT, mostró una asociación más fuerte con el riesgo cardiovascular que la placa carotídea.
Área de la Ciencia:
- Biología Vascular Biología Vascular
- Investigación de Enfermedades Cardiovasculares Investigación de Enfermedades Cardiovasculares
- Análisis de imágenes médicas Análisis de imágenes médicas.
Sus antecedentes:
- La evaluación subclínica de la aterosclerosis a través de ultrasonido ayuda a predecir el riesgo cardiovascular.
- Los métodos actuales para cuantificar la carga de placa exhiben variabilidad.
- Se desarrolló un nuevo método, el espesor ponderado total de la placa (wTPT), para medir la carga de la placa.
Objetivo del estudio:
- Evaluar la asociación de la wTPT con los factores de riesgo cardiovascular.
- Para evaluar la correlación de la wTPT con el riesgo cardiovascular estimado.
- Para comparar la wTPT con las medidas convencionales de placa para la predicción del riesgo cardiovascular.
Principales métodos:
- Utilizó ultrasonido para evaluar las arterias carótida y femoral en 5.180 participantes (edad 45-74).
- Carga de placa cuantificada utilizando wTPT, espesor máximo de placa (MPT), recuento de placas y número de arterias con placa.
- Riesgo cardiovascular estimado utilizando la ecuación NORRISK-2.
Principales resultados:
- La prevalencia de la placa fue alta (96,1% en general).
- La wTPT femoral fue significativamente más alta que la wTPT carotídea.
- La wTPT demostró una correlación más fuerte con el riesgo cardiovascular estimado (0,66) en comparación con la MPT (0,61), el recuento de placas (0,62) y el número de arterias con placa (0,59).
- La wTPT femoral (0,59) se correlacionó más fuertemente con el riesgo cardiovascular que la wTPT carotídea (0,55).
Conclusiones:
- La presencia de placa es casi universal en individuos asintomáticos, lo que hace necesaria la estratificación de la carga de placa.
- wTPT muestra una asociación superior con el riesgo cardiovascular estimado en comparación con las medidas tradicionales de placa.
- La carga de la placa femoral, evaluada por wTPT, está más fuertemente relacionada con el riesgo cardiovascular que la carga de la placa carotídea.

783
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
