Abstract
Arterial stiffness, a risk factor for cardiovascular disease, can be measured using pulse wave velocity (PWV) and augmentation index (AIx). We studied sex-specific associations between carotid-femoral PWV (cfPWV), brachial-ankle PWV (baPWV), aortic PWV (aoPWV), aortic (aoAIx), and brachial (baAIx) AIx with echocardiographic parameters. Data of 1150 participants of the Study of Health in Pomerania (SHIP-Trend 1; 530 men; median age 53 years; inter quartile range (IQR) 44 to 64) were used. Echocardiography assessed common structural and functional cardiac parameters. PWV and AIx were measured using the Vascular Explorer. Multivariable linear regression models were applied. In men, a higher brAIx was related to a greater right ventricular diameter (RV) (β 0.037; CI 0.003 to 0.148). A one m/s higher baPWV was associated with a smaller RV (β -0.037; CI -0.168 to -0.021) and right ventricular outflow tract (RVOT; β -0.029; CI -0.141 to -0.026). In men, a higher aoAIx (β 0.028; CI 0.01 to 0.122) and brAIx (β 0.029; CI 0.017 to 0.13) were associated with a greater RVOT. In women, a one m/s higher aoPWV (β 0.025; CI 0.006 to 0.105) was associated with a larger RV and a one m/s higher baPWV (β -0.031; CI -0.124 to -0.001) was inversely related to RVOT. In women, PWV associated with right ventricular dimensions, while in men, baPWV and AIx were related to right ventricular parameters. This suggests potentially sex-specific relations between PWV and cardiac structure and function.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
