ABSTRACT
Background: Whether women have a higher risk of adverse events compared with men following coronary angiography (CAG) and percutaneous coronary intervention (PCI) remains controversial. We aimed to investigate the sex differences in characteristics, treatments and outcomes among patients undergoing CAG and PCI in a large Chinese cohort. Methods: We analyzed patients undergoing CAG and/or PCI in this multi-center registry cohort study Cardiorenal ImprovemeNt II (CIN-II) in 5 Chinese tertiary hospitals from 2007 to 2020. Clinical characteristics, treatment (discharge medication and PCI) and in-hospital outcomes (mortality and major bleeding) were compared between women and men. Results: Totally 141,459 patients underwent CAG (44,362 [31.4%] women), of which 69,345 patients underwent PCI (15,376 [22.2%] women). Women were older (64.4 vs. 60.8 years), had more chronic comorbidities and lower PCI rate for stable coronary artery disease (CAD) than men (52.8 vs. 64.2%). Women received less CAG and PCI procedures. Among women undergoing PCI they received similar discharge medication treatment. In addition, women undergoing PCI had mildly lower rate of major bleeding (0.2 vs. 0.3%, P = 0.033) but higher in-hospital mortality (1.2 vs. 0.8%, P < 0.001). After adjustment, women had a higher risk in the major bleeding (adjusted odds ratio, 2.04 [95% CI: 1.07 to 3.62]), and the in-hospital mortality (adjusted odds ratio, 1.87 [95% CI: 1.36 to 2.56]). Conclusion: Among our Chinese cohort, women are older with more chronic comorbidities, receiving less PCI procedure and similar discharge medication treatment. Women have nearly 90% higher risk of in-hospital mortality and over 1-fold increased risk of major bleeding after PCI compared with men.
ABSTRACT
Sinperca chuatsi usually refuses eating dead bait or man-made feed due to its specific feeding habit. It was showed that some S. chuatsi could be induced to take lifeless bait with domestication gradually after long-term of cultivation. High cost, serious pollution, severe diseases, and other problems of S chuatsi cultivation can be solved effectively by selecting those liable to domestication via molecular marker and treating them with artificial feed on a large scale. Lipoprotein lipase, one of the key enzymes in lipoprotein metabolic processes, provides energy by catalyzing the oxidation of triglycerides lie in the core of chylomicron and very low density lipoprotein (VLDL) into glycerin and fatty acid, and saves energy. In order to search the distribution of the alleles and genotypes of lipoprotein lipase gene (lipoprotein LPL) gene in two feed habit domestication phenotype populations, SNP genetic polymorphisms in 6 and 7 introns and 6, 7, and 8 exons of LPL in S. chuatsi were analyzed by PCR product sequencing method. Three SNPs A25T, G26T, and C29G were detected, two of which were non-synonymous mutations. It was indicated by Chi-square test that the analysis between domesticated and undomesticated populations show no significant difference (P>0.05) between the three SNPs and feed habit. However, diplotype 2 in the two population showed significant difference (P<0.05) by assembling different genotypes of the three SNPs into five diplotypes. Polymorphic analysis of partial fragment of LPL genome in S. chuatsi was accomplished successfully. Therefore, LPL gene can be considered as a candidate gene and genetic marker for feed habit domestication in S. chuatsi, which lays the foundation for the work of molecular marker and selecting breed, which has extensive application prospect.
