Objective: The aim of this study was to evaluate electrical and echographic cardiovascular abnormalities during cirrhosis at the Brazzaville University Hospital. Patients and Methods: We conducted a cross-sectional analytical study over a 2-year period at the Brazzaville Universitary Hospital. Cirrhotic patients at least 18 years of age who had undergone electrocardiogram and echocardiography were included. Patients with cardiac cirrhosis, hepatocellular carcinoma or spontaneous bacterial peritonitis were excluded. The outcome variables were cardiac electrical and echographic abnormalities. Data were analyzed using Epi info 7.2 software. Pearson’s chi-square, Fisher’s exact and Student’s exact tests were used to compare proportions and means at a significance level of 0.05. Results: A total of 76 cirrhotic patients were recruited out of 186 patients, i.e. 40.9% of cirrhotic patients. There were 48 men and 28 women, for a sex ratio of 1.7. The median age was 56 (IQR 41.5 - 69.0). QTc prolongation, microvoltage and sinus tachycardia were the most frequent electrical disorders, respectively in 19 (29.7%), 11 (17.2%) and 11 (17.2%) cases. Electrical disorders were statistically related to cirrhosis stage (p = 0.0364). The most frequent ultrasound disorders were left ventricular systolic failure 11 (28.9%) and dilated cardiomyopathy 8 (21.1%). Seven (9.2%) patients had high pulmonary arterial pressure. Death, observed in 12 cases (15.8%), was statistically linked to the presence of echocardiographic disorders (p = 0.0089) and congestive heart failure (p = 0.0001). Conclusion: The search for cardiac disorders should be systematic during decompensated cirrhosis to detect potentially fatal abnormalities.展开更多

Methods： With the use of polysomnography, 262 adult habitual snorers were examined and divided into the OSAHS group and the Non-OSAHS group （control）. Using ambulatory electrocardiogram and blood pressure measurement, daily nocturnal rhythm of blood pressure, hypertension, heart rate variability, some arrythmias and angina pectoris of coronary heart disease were monitored and compared between the two groups, before and after 14 days of treatment with NCPAP in the OSAHS group. Results.This study indicated a higher incidence （39.6%） of OSAHS in adult snorers and demonstrated that there was a significantly higher incidence of hypertension, disappearance of the daily nocturnal rhythm of blood pressure, poor effectiveness of nitrate on angina pectoris of coronary heart disease, decreased heart rate variability during sleep, increased arrythmias and lower SpO2 levels in the OSAHS group than in the Non-OSAHS group. After NCPAP treatment during sleep, snoring control, significantly higher SpO2 and lower apnea hypopnea indices were achieved in the OSAHS group; heart rate variability and daily nocturnal rhythm of blood pressure returned to normal levels. Conclusion：The results of this research suggested that there was a close relationship between the development of OSAHS and some cardiovascular disorders. Furthermore, NCPAP treatment was effective not only on OSAHS but also on coexisting cardiovascular disorders.展开更多

In the present study, we aimed to investigate the association between circulating levels of high sensitive C-reactive protein (hs-CRP) and various biomarkers for hepatic, diabetic, and cardiovascular health. The retrospective analysis included 438 individuals who were tested for these panels simultaneously at Vibrant America Clinical Laboratory. The study population included free-living individuals without any preexisting clinical conditions. Among the cardiovascular markers, a positive correlation and significant association was found between high levels of hs-CRP and serum levels of triglycerides (r = 0.0964, p −0.1423, p −0.1216, p < 0.0105) with circulating levels of hs-CRP. Among all the diabetic markers, glucose (r = 0.1547, p < 0.0011) and glycated serum protein (r = 0.1725, p < 0.0003) were positively correlated with circulating hs-CRP. In the hepatic panel, AST, a transaminase that plays a vital role in amino acid metabolism, was found to have a strong positive correlation with hs-CRP (r = 0.2139, p < 0.0001). In conclusion, the results clearly show the association of hs-CRP with diabetic, hepatic, and cardiovascular risk factors indicating its central value as a key marker for several lifestyle-associated disorders.展开更多

Methods: The Sprague-Dawley rats were randomly divided into 5 groups with 7 rats in each group according to their weights,including control, model, fluoxetine(FLXT, 10 mg/kg), low-dose YXNS(LYXNS, 100 mg/kg), and high-dose YXNS(HYXNS, 300 mg/kg) groups. All rats were pretreated with corresponding drugs for 12 weeks. The rat model of MI and depression was constructed by ligation of left anterior descending coronary artery and chronic mild stress stimulation. The echocardiography, sucrose preference test, open field test, and forced swim test were performed. Myocardial infarction(MI) area and myocardial apoptosis was also detected. Serum levels of interleukin(IL)-6, IL-1β, tumor necrosis factor-α(TNF-α), 5-hydroxytryptamine(5-HT), adrenocorticotrophic hormone(ACTH), corticosterone(CORT), and norepinephrine(NE) were determined by enzyme linked immunosorbent assay. The proteins of adenosine 5’-monophosphate-activated protein kinase(AMPK), p-AMPK,peroxisome proliferator-activated receptor gamma coactivator-1α(PGC-1α), and nuclear respiratory factor 1(NRF1) in heart were detected by Western blot analysis. The expression levels of TNF-α, IL-6, indoleamine 2,3-dioxygenase(IDO1), kynurenine 3-monooxygenase(KMO), and kynureninase(KYNU) in hippocampus were detected by real-time quantitative polymerase chain reaction. Results: Compared with the model group,the cardiac function of rats treated with YXNS significantly improved(P<0.01). Meanwhile, YXNS effectively reduced MI size and cardiomyocytes apoptosis of rats(P<0.01 or P<0.05), promoted AMPK phosphorylation,and increased PGC-1α protein expression(P<0.01 or P<0.05). HYXNS significantly increased locomotor activity of rats, decreased the levels of TNF-α, IL-6 and IL-1β, and increased the serum levels of 5-HT, NE, ACTH,and CORT(all P<0.05). Moreover, HYXNS decreased the m RNA expressions of IDO1, KMO and KYNU(P<0.05).Conclusions: YXNS can relieve MI by enhancing myocardial energy metabolism. Meanwhile, YXNS can alleviate depression by resisting inflammation and increasing availability of monoamine neurotransmitters. It may be used as a potential drug to treat comorbidity of MI and depression.展开更多
