RESUMO

BACKGROUND: Recently, trimethylamine N-oxide (TMAO) unexplained gut microbe has been proposed as a promising risk factor for atherosclerotic cardiovascular disease (CVD) pathogenesis and adverse events. The relationship of TMAO with coronary atherosclerotic burden has been evaluated in patients with stable coronary artery disease and ST-segment elevation myocardial infarction, but still needs to be explored in newly diagnosed non-ST-segment elevation myocardial infarction (NSTEMI) patients. MATERIAL AND METHODS: A prospective, single-center, SZ-NSTEMI trial (ChiCTR1900022366) is underway to investigate the relationship of TMAO with the severity and prognosis of coronary atherosclerosis in newly diagnosed NSTEMI patients who will undergo coronary angiography with primary percutaneous coronary intervention (pPCI). The primary endpoint of the study will be assessed the association of TMAO with coronary atherosclerotic severity quantify by the number of diseased coronary arteries and SYNTAX score after the coronary angiography. The secondary endpoints will be identified the TMAO as a prognostic biomarker for the short (1 month) and long-term (12 months) major cardiovascular and cerebrovascular events (MACCEs) rate including myocardial infarction, target vessel revascularization, stroke, heart failure, all-cause rehospitalization, and all-cause mortality after the pPCI. The blood samples will be collected from each patient before the procedure to measure the TMAO by isotope dilution high-performance liquid chromatography. In conclusion, SZ-NSTEMI will be the first cohort that will be investigated the association of TMAO with the severity and prognosis of coronary atherosclerotic burden in NSTEMI patients, aiming to identify TMAO as a predictor and a prognostic biomarker.

RESUMO

Objective To analyze the preoperative related factors of early weaning of infants with congenital heart disease after operation. Methods From January ,2014 to January ,2017 in Pediatric Cardiology CICU , infants with congenital heart disease were selected as research objects. The clinical data were retrospectively collect ed and the relationship between preoperative influencing factors and postoperative early weaning were analyzed. Early weaning meant mechanical ventilation time was shorter than 24 h and late weaning meant longer than 24 h. Results Single factor analysis showed that early weaning success rate was related to preoperative cardiac function grade 1,NNIS grade 0~1,ASA grade 1,no lung infection and no or mild pulmonary hypertension(average P<0.05). Non conditional logistic regression analysis showed that preoperative heart function grade 1 was an indepen-dent influencing factor,with OR value(95%CI)of 3.9(1.9~7.7). Conclusions In infants with congenital heart disease,preoperative heart function grade 1,NNIS grade 0 ~ 1 ,ASA grade 1,no lung infection and no or mild pulmonary hypertension benefit early withdrawing of ventilator and preoperative cardiac function grade 1 is an inde-pendent factor for early weaning.

RESUMO

QRS-waves integral can reflect the activities of ventricular depolarization. In this paper are analyzed the nonlinear characters in QRS-waves integral: reconstructing state space with these integral signals after nonlinear noise reduction, calculating its attractor dimension and the largest Lyapunov exponents. With the results based on MIT-BIH database we proposed that QRS-waves integral is of chaos nature. When compased with HRV nonlinear analysis, QRS-waves integral analysis was found to be of more advantages in some cases such as premature ventricular contraction. This QRS-waves integral nonlinear analysis may be of use in evaluating clinical cardiac function.
