BACKGROUND AND AIMS: The relationship between peptic ulcer, autonomic activity and the incidence of Helicobacter pylori infection in untreated hypertensive patients complicated with peptic ulcer were evaluated. METHODS: Ten hypertensive patients with peptic ulcer (HT-PU group), 15 untreated essential hypertensive patients without peptic ulcer (HT group) and 10 normal subjects (N group) were enrolled, and a power spectral analysis was performed in each subject. A biopsy urease test was used to detect infection by H. pylori. RESULTS: No significant differences were observed in the values of mean low-frequency (LF) power between the three groups. However, the mean high-frequency (HF) power in the HT-PU group was significantly greater than those of the HT and N groups (P<0.01). The mean LF/HF ratios in the HT-PU and HT groups were significantly greater than that of the N group (P<0.01). With respect to H. pylori infection, no significant differences between the three groups were observed. Sympathetic activity (LF power) was increased in the HT and HT-PU groups. Furthermore, parasympathetic activity (HF power) was increased in the HT-PU group. CONCLUSIONS: These findings suggest the participation of increased parasympathetic activity in peptic ulcer patients. Therefore, it is suggested that new techniques, such as spectral analysis of heart rate variability, as used in this study, will clarify the relationship between peptic ulcer and autonomic nervous function. 相似文献

Background: Serum uric acid (UA) level is associated with prognosis in cardiovascular disorders such as sustained hypertension, diabetes mellitus and chronic kidney diseases. Increased UA levels in sustained hypertension may reflect early renal vascular alterations. However, it remains unclear if serum UA is associated with endothelial dysfunction in masked hypertensive patients. Methods: A total of 100 individuals (57% men and 43% women; mean 45?±?8 years) with masked hypertension were included in the present study. The clinical and laboratory data were collected. Endothelial function was estimated by flow-mediated dilatation (FMD) of the brachial artery and expressed as percentage change relative to baseline diameter. Results: Univariate regression analysis showed that the FMD was significantly negative correlated with uric acid (r?=??0.300, p?=?0.002), ambulatory 24-h systolic blood pressure (SBP) (r?=??0.275, p?=?0.008), hs-CRP (r?=??0.222, p?=?0.033) and diastolic aortic diameter (r?=??0.243, p?=?0.019). In multivariate linear regression analysis, only uric acid levels and ambulatory 24-h SBP were significantly associated with FMD. Conclusion: There was an independent correlation between UA and FMD, and a higher UA level was related to worse endothelial function which may contribute to hypertension and cardiovascular morbidity. 相似文献

Background
Nilotinib is a second-generation tyrosine kinase inhibitor with significant efficacy as first- or second-line treatment in patients with chronic myeloid leukemia. Despite preclinical evidence indicating a risk of prolongation of the QT interval, which was confirmed in clinical trials, detailed information on nilotinib’s cardiac safety profile is lacking.Design and Methods
Here, we retrospectively assessed cardiovascular risk factors in 81 patients who were being or had previously been treated with nilotinib therapy and evaluated cardiovascular parameters by longitudinal monitoring of the QT interval and left ventricular ejection fraction. Detailed information on the occurrence and management of defined cardiac adverse events was extracted.Results
The median duration of nilotinib therapy was 26 months (range, 1–72). The median QT interval at baseline was 413 msec (range, 368–499 msec). During follow-up, the median QT was not significantly different from the baseline value at any time-point. Sixteen of 81 patients (20%) had new electrocardiographic changes. Cardiac function, as assessed by measurement of left ventricular ejection fraction, did not change significantly from baseline at any time-point. During a median follow-up of 44 months (range, 2–73), seven patients (9%), all of whom had received prior imatinib therapy, developed 11 clinical cardiac adverse events requiring treatment. The median time from the start of nilotinib therapy to an event was 14.5 months (range, 2–68). Five of seven patients were able to continue nilotinib therapy with only one brief interruption.Conclusions
Whereas new electrocardiographic abnormalities were recorded in 20% of all patients and some of them developed severe or even life-threatening coronary artery disease, QT prolongation, changes in left ventricular ejection fraction, and clinical cardiac adverse events were uncommon in patients treated with nilotinib. 相似文献10.

Concerns about metabolic complications often disturb prolonged use of diuretics in Japan. We investigated 3-year safety and efficacy in Japanese patients with hypertension who were uncontrolled with angiotensin receptor blocker or angiotensin-converting enzyme inhibitor regimens and then switched to losartan (50 mg)/hydrochlorothiazide (12.5 mg; HCTZ) combinations. Blood pressure decreased favorably and maintained a steady state for 3 years (157 ± 16/88 ± 11 mm Hg to 132 ± 13/75 ± 9 mm Hg, P < .0001). Metabolic parameters maintained a limited range of changes after 3 years, and adverse events were markedly decreased after 1-year treatment. The losartan/HCTZ combination minimized diuretic-related adverse effects and thus may be useful for the treatment of Japanese patients with hypertension. 相似文献

A direct relationship between serum uric acid and blood pressure (BP) has been reported, but the possible confounding impact of diet on this association is unclear. The authors performed a cross‐sectional analysis in the representative German Health Interview and Examination Survey for Adults (n=6788, aged 18–79 years). In adjusted regression models considering dietary factors, each 1‐mg/dL higher uric acid value was associated with a 1.10‐mm Hg (P=.0002) and a 0.60‐mm Hg (P=.04) higher systolic BP among participants younger than 50 years and participants 50 years and older, respectively. For diastolic BP, uric acid was a significant predictor (β=0.71 mm Hg, P=.0001) among participants younger than 50 years and for participants 50 years and older without antihypertensive treatment. Adjusted odds ratios of hypertension for participants with hyperuricemia were broadly similar in younger (odds ratio, 1.71; P=.02) and older (odds ratio, 1.81; P=.0003) participants. Uric acid is a significant predictor of systolic BP and hypertension prevalence in the general adult population in Germany independently of several known dietary BP influences. 相似文献

Serum uric acid (UA), as an antioxidant, has been associated with hypertension in the general population. Hypertension is highly prevalent in patients with polymyositis and dermatomyositis (PM/DM). Owning elevated levels of reactive oxygen species, patients with PM/DM have lower concentrations of UA in comparison with healthy people. We explored a potential association between UA levels and hypertension in PM/DM and evaluated whether this association is independent of hypertension risk factors, PM/DM characteristics and relevant drugs. A total of 472 PM/DM patients were assessed. UA and related laboratory data were measured. Demographic, hypertension-related factors, PM/DM characteristics and drug use were assessed as potential covariates. Results were analyzed using logistic models to test the independence of the association between UA and hypertension. UA levels were higher in hypertension subjects compared to non-hypertensive PM/DM patients [284.70 (239.93-357.38) vs 264.00(222.50-322.75), p = .017]. When adjusted for hypertension risk factors, PM/DM characteristics and drugs, the odds of being a hypertensive PM/DM patient per 1 μmol/L UA increase were significantly increased: odds ratio = 1.473 (95% confidence interval:1.063-2.042, p = .020). This cross-sectional study suggests that UA levels are independently associated with hypertension in PM/DM patients. 相似文献
