Changes in systolic blood pressure over time in healthy cats and cats with chronic kidney disease

Changes in systolic blood pressure over time in healthy cats and cats with chronic kidney disease

Human patients with end stage renal disease almost invariably suffer from hypertension, but in human CKD patients there is no correlation between serum creatinine concentration and blood pressure, 25,26 although a decline in creatinine clearance is mildly cor- related with mean blood pressure in healthy subjects. 15 It has been demonstrated that baseline creatinine is an independent risk factor for the development of azotemic CKD in cats. 7 This study shows that creatinine is also an independent risk factor for the development of hypertension and that CKD cats are more likely to be diagnosed with clinically significant hypertension. His- torically it has been suggested that hypertension in most cats is secondary to CKD, and several mechanisms, such as activation of the renin-angiotensin-aldosterone system (RAAS) and fluid retention have been described. 11,27,28 A recent study showed that plasma renin activity is suppressed in hypertensive cats, whereas plasma aldosterone concentration is increased, although there was a substantial overlap among groups. 28 How- ever, it could be hypothesized that CKD and hyperten- sion share a pathophysiological basis that is not yet understood. The possibility exists that feline hypertension has a genetic component, like essential

Lower Systolic Blood Pressure

Lower Systolic Blood Pressure

Medications to Lower LDL Cholesterol Medications are often necessary to get your LDL cholesterol level below 100 mg/ dl. Lifestyle changes to lower cholesterol are still important even when medications are prescribed. These changes can reduce the amount of medication that you need to take. This will keep cost and side effects to a minimum. There are several types of medications available that work well and that are safe. Talk with your healthcare provider to decide which treatments are right for you.

The TRINITY Study: distribution of systolic blood pressure reductions

The TRINITY Study: distribution of systolic blood pressure reductions

In the TRINITY study population, small changes were observed in each serum chemistry and hematologic parameter across the treatment groups (data not shown). Key chemistry parameters included alanine transaminase, aspartate transaminase, blood urea nitrogen, creatinine, sodium, potassium, and bicarbonate; key hematology parameters included hemoglobin, hematocrit, white blood cell count, and platelet count. These changes had no apparent relationship to treatment regimen and were not considered clinically significant. 11

Non Invasive Estimation of Systolic Blood Pressure and Diastolic Blood Pressure Using Photoplethysmograph Components

Non Invasive Estimation of Systolic Blood Pressure and Diastolic Blood Pressure Using Photoplethysmograph Components

The IBP, HR, and PPG components were measured and analyzed in 6 dogs. In summary, the current study indi- cates that the DC component of PPG is inversely propor- tional to static blood volume in the vessels and tissues. In addition, the AC component of PPG shows subtle changes in the arterial system due to cardiac contraction and relaxa- tion and provides information regarding vascular comp- liance and resistance. Therefore, these results support the possibility that the PPG components may be used for easy and noninvasive measurement of hemodynamic changes in the cardiovascular system such as blood pressure.

Genome wide association of trajectories of systolic blood pressure change

Genome wide association of trajectories of systolic blood pressure change

Results: The semiparametric LCGM approach identified 5 trajectory classes that captured SBP changes across age. Each LCGM identified trajectory group was ranked based on the average number of cumulative years as hypertensive. Using a pairwise comparison of these classes the heritability estimates range from 12 to 94 % (SE = 17 to 40 %). Conclusion: These identified trajectories are significantly heritable, and we identified a total of 8 promising loci that influence one ’ s trajectory in SBP change across age. Our results demonstrate the potential utility of capitalizing on extant genetic data and longitudinal SBP assessments available through GAW19 to explore novel analytical methods with promising results.

The Effect Paraoxonase-1, Hydrogen Peroxide and Adiponectin Changes on Systolic and Diastolic Blood Pressure of Men’s with High Blood Pressure Fallowing to 12 Week Moderate Aerobic exercise

The Effect Paraoxonase-1, Hydrogen Peroxide and Adiponectin Changes on Systolic and Diastolic Blood Pressure of Men’s with High Blood Pressure Fallowing to 12 Week Moderate Aerobic exercise

Physiological markers and serum levels of Adiponectin, Paraoxonase-1 (PON-1) and Hydrogen Peroxide (H 2 O 2 ) were assessed in baseline stage, 4th weeks, 8th weeks and twelfth weeks. The Liner Mixed Model was used to evaluate the association between markers. Results: Statistical analysis showed no significant relation between Adiponectin and PON-1 with systolic blood pressure (SBP) and diastolic blood pressure (DBP) (Respectively: P=0.150, P=0651 and P=0.165, P=0.520). However, the relationship between H2O2 with SBP and DBP (Respectively: P=0.020 and P=0.048) reported significantly.

Impact of systolic blood pressure limits on the diagnostic value of triage algorithms

Impact of systolic blood pressure limits on the diagnostic value of triage algorithms

Therefore, it should be discussed if significant changes in the algorithm design need to be carried out to ensure that the use of FTS in combat situations is safe for af- fected soldiers. Every other algorithm, apart from FTS, performed better in trauma patients than in non-trauma patients. This observation is in line with a study on ac- curacy of primary diagnosis in the emergency room compared to the primary diagnosis at discharge – which was considerably higher for trauma compared to non- trauma diagnoses [17].

CiteSeerX — Ascorbic Acid Status and Subsequent Diastolic and Systolic Blood Pressure

CiteSeerX — Ascorbic Acid Status and Subsequent Diastolic and Systolic Blood Pressure

Cross-sectional studies, however, provide only weak evidence for a causal relationship, because vitamin C intake and blood levels are correlated with other factors, such as dietary fiber and carotenoids. A number of intervention studies have been conducted, but most have had various methodological problems that make them difficult to interpret. 2 Many were very small, and some had no control group, permitted placebo subjects to take multivitamins, did not exclude smokers, did not control alcohol or other dietary intake, or did not control body weight changes or other factors that might affect BP. A few intervention studies have been conducted since the review by Ness et al. 5– 8 Miller et al 7 administered vitamin C, vitamin E, and beta-carotene to 297 older persons and found no BP difference between the antioxidant and placebo groups. However, all subjects, including the pla- cebo group, were permitted to take a multivitamin that contained vitamins C and E and beta-carotene during the

Antihypertensive Drug Management to Achieve Systolic Blood Pressure <120 mmhg in SPRINT

Antihypertensive Drug Management to Achieve Systolic Blood Pressure <120 mmhg in SPRINT

Safety Monitoring Regular safety monitoring was an important part of the SPRINT visits. For example, ACE inhibitors, ARBs, aldosterone antagonists and diuretics can result in clinically significant alterations of serum electrolytes and kidney function. Thus, after the initiation of these agents, a chemistry profile was also obtained according to the table below (based on the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines). Switching from one drug (e.g., ACE inhibitor) to another drug (ARB) in the same class is not considered as drug initiation, but changes in equivalent dosages should be taken into consideration when deciding the frequency of monitoring.

POSTURAL CHANGES IN BLOOD PRESSURE IN NORMOTENSIVE PERSONS

POSTURAL CHANGES IN BLOOD PRESSURE IN NORMOTENSIVE PERSONS

ABSTRACT Purpose – The primary purpose of this study is to observe the postural variation of blood pressure and to compare to find out error difference. Blood pressure is a measure of cardiovascular reactivity reflecting autonomic function. Short Term regulatory mechanism (Baroreceptor reflex) is operated to maintain normal blood pressure. Pooling of blood in lower extremities occur due to gravitational effects. It reduces venous return and stroke volume with a fall in systolic blood pressure.

CHANGES IN BLOOD PRESSURE DUE TO POSTURAL VARIATION

CHANGES IN BLOOD PRESSURE DUE TO POSTURAL VARIATION

Purpose: In this study, we wanted to correlate the change in the blood pressure in supine position on immediately standing up to the change in blood pressure after 2 minutes of standing in hypertensive and normotensive individuals. Materials and Method: By keeping inclusion and exclusion criteria, the 50 subjects selected for this study were aged between 15 and 55 years, were of both sexes and were categorized into four groups based on their age. By taking the position of the patient into consideration, blood pressure was recorded in the lying and the standing posture. Error difference in blood pressure was found in standing position by double recording. Questionnaires evaluated about smoking habits, medication use and history of past illness. Statistical analysis was done by t-test. Result: From the above study, it is found that blood pressure in hypertensive patients varies in lying position than in standing position (p < 0.01) with less error in blood pressure recording (p < 0.05). It also shows that in hypertensive persons, systolic blood pressure increases compared to diastolic blood in standing position as well as sitting position. Conclusion: Thus it was concluded that there is significant correlation between blood pressure and posture which varies in lying position than in standing position in hypertensive patients.

Predicting ischaemic stroke subtype from presenting systolic blood pressure: the BASIC Project

Predicting ischaemic stroke subtype from presenting systolic blood pressure: the BASIC Project

The estimated models were used to predict the probability of each stroke subtype for a continuous range of values of SBP. The predicted probabilities were then plotted against SBP. In practical situa- tions, categories of SBP may be more useful than continuous changes in SBP. Thus, the models were re-estimated using quartiles of SBP. Bar graphs depicting the odds ratios (OR) for each subtype were constructed based on the model with SBP quartiles. For all calculations, the highest SBP quar- tile was the referent. The odds of cardioembolic, NLUE and large vessel versus small vessel occlu- sion (referent stroke subtype) were calculated to depict the association between subtype and quartiles of SBP. Additionally, the odds of small vessel occlusion versus all other stroke subtypes combined were computed to depict the association between small vessel occlusion and increasing SBP.

Association between inflammation and systolic blood pressure in RA compared to patients without RA

Association between inflammation and systolic blood pressure in RA compared to patients without RA

changes in inflammation and changes in BP. In RA, hav- ing a high level of inflammation is typically a temporary state due to an RA flare or inadequate response to treat- ment. Thus, subjects with RA routinely have large changes in CRP in the course of routine care, providing an opportunity to study the association between longitu- dinal changes in inflammation and BP. For this study, we focused on patients with RA who had an increase or decrease in CRP by ≥ 10 mg/L, which is considered a significant change in inflammation [25, 26]. We applied linear mixed effect models to account for correlation be- tween repeated measures within subjects to examine the associations between changes in CRP and changes in SBP. We defined baseline as the day of their first same- day CRP and BP measurements during the study period.

Cell phone restriction correlates with increased systolic blood pressure and GSR but not heart rate

Cell phone restriction correlates with increased systolic blood pressure and GSR but not heart rate

Overall, the results collected during the study show modest evidence for the onset of the acute stress response in conjunction with separation from the cell phone. The main measure consistent with our original prediction came from the blood pressure results. While the mean systolic pressure for the control group showed a minor decrease across the test period (4 mmHg), the mean systolic pressure for the experimental group showed a slight rise of approximately 5 mmHg. This corroborates the prediction that the blood pressure for the experimental group would increase throughout the test, compared to the control. Diastolic blood pressures show less significant changes throughout the test period, and despite the apparent increase in experimental mean diastolic pressures from the 0 to 45 minute time points, the mean diastolic pressure

Postural Changes In Blood Pressure Associated With Ageing

Postural Changes In Blood Pressure Associated With Ageing

The present study reveals to determine the patterns of orthostatic blood pressure (OBP) changes, symptoms and clinical factors in different aged groups. Sixty subjects of different aged group between 20 and 90 were used in this study. Among these groups, different measurements of BP were done in lying as well as standing position at two time intervals (1min, 3min) to check their orthostatic hypotension (OH). The Results showed that OH significantly increased in the age group 71.1 and moderate in 39.8 and no changes occurred in 20.55. The symptoms of head ache, blurred vision, falling and light headedness as well as blood hemoglobin levels were independent of OH in all aged groups. Based on the nutritional status, Body Mass Index was measured in these subjects and identified as 72% well nourished; 4% under-nourished and 24% overweight. The systolic OH (P<0.01) was more common among the elderly subject than diastolic OH (P>0.05). Also prevalence was similar in either gender of elderly group. Based on the present study, we conclude that OH incidence increases with increase in age and symptoms are independent of physical recording.

Phenomenon of declining blood pressure in elderly - high systolic levels are undervalued with Korotkoff method

Phenomenon of declining blood pressure in elderly - high systolic levels are undervalued with Korotkoff method

Concerning the possible pitfalls during blood pressure measurement using Korotkoff technique in the elderly, we aimed to study if aging-related changes in BP could be observed in the same extent by Korotkoff as Strain gauge technique, and which of them was best correlated to Ambulatory Blood Pressure Monitoring. Thanks the opportunity to examine BP with both Korotkoff and strain gauge technique in the cohort of elderly men twice during their life, we could compare the time- change in BP with vascular risk factors, as well as with established markers of vascular disease. The null hypothesis was that there would be no difference between age-related BP decline examined with these two methods.

Systolic blood pressure and mortality

Systolic blood pressure and mortality

One way to disentangle the confounding is to assess whether antihypertensive agents that have similar effects on systolic blood pressure have the same or different effects on outcomes. For example, Psaty and colleagues 10 have shown that low-dose diuretics, high-dose diuretics, and -blockers all lower blood pressure by about the same amount, but effects on outcome differed significantly. Another way to disentangle the confounding is to assess whether drug action benefits survival independently of systolic blood pressure. Borghi and Ambrosioni 11 reported a protective role for inhibitors of angiotensin-converting enzyme, even in hypertensive diabetic patients. They noted that such agents can significantly decrease the occurrence of major cardiovascular events (coronary heart disease and stroke) largely independent of blood pressure control, an effect not seen with the use of calcium antagonists. The beneficial effects of -blockers, independent of blood pressure, include protective effects against arrhythmias, ischaemia, and atherosclerosis. Many other studies show that antihypertensive agents favourably affect many cardiovascular parameters, including survival, but that their effects on systolic blood pressure may be of no consequence.

Predicting systolic blood pressure using machine learning

Predicting systolic blood pressure using machine learning

learning technique, specifically artificial neural network, is investigated to predict the systolic blood pressure by correlated variables (BMI, age, exercise, alcohol, smoke level etc.). The raw data are split into two parts, 80% for training the machine and the remaining 20% for testing the performance. Two neural network algorithms, back-propagation neural network and radial basis function network, are used to construct and validate the prediction system. Based on a database with 498 people, the probabilities of the absolute difference between the measured and predicted value of systolic blood pressure under 10mm Hg are 51.9% for men and 52.5% for women using the back- propagation neural network. With the same input variables and network status, the corresponding results based on the radial basis function network are 51.8% and 49.9% for men and women respectively. This novel method of predicting systolic blood pressure contributes to giving early warnings to young and middle-aged people who may not take regular blood pressure measurements. Also, as it is known an isolated blood pressure measurement is sometimes not very accurate due to the daily fluctuation, our predictor can provide another reference value to the medical staff. Our experimental result shows that artificial neural networks are suitable for modeling and predicting systolic blood pressure.
