Anesthesia reduces blood pressure and cerebral blood flow is normally considered to be maintained despite marked changes in blood pressure. Vascular surgical patients are often elderly, have high blood pressure and atherosclerosis and in these patients cerebral blood flow may decrease if blood pressure is reduced during anesthesia. The purpose of this study is to assess the effect of blood pressure for preservation of cerebral blood flow during anesthesia in vascular surgery. T...
The purpose of this academic lead study is to explore ideal blood pressure targets and optimum individualized anti-hypertension strategies in acute severe stroke.
Nitroprusside is used commonly in the Intensive Care Unit for long periods of time in order to reduce blood pressure. It is not known if the body compensates over time to the blood pressure lowering, and if when the nitroprusside is stopped the blood pressure goes up at a faster rate and is higher than it was at the start of the treatment. This study will answer these questions.
PRECIOUS Study aims to evaluate the efficacy and safety of therapy with fixed-dose combination (FDC) of perindopril/amlodipine (Amlessa®) and FDC of perindopril/indapamide/amlodipine (Co-Amlessa®) on blood pressure reduction in both previously untreated patients and patients with previous antihypertensive therapy. Adult patients with AH who are treatment-naïve with systolic blood pressure (SBP) from 150 mmHg or higher AND/OR diastolic blood pressure (DBP) from 95 mmHg or hi...
Right ventricular (RV) dysfunction in cardiac surgery is an independent risk factor for morbidity and mortality. Raising the systemic blood pressure with norepinephrine seems to have a positive influence on the right ventricular function in several animal studies. The current study is designed to evaluate the effect of a higher blood pressure on the RV function in post cardiac surgery patients.
Current management of hypertension in PD motor fluctuators is flawed. The current practice often is to treat transient hypertensive spikes reported by patients or measured in clinics with anti-hypertensive medications. This may contribute to morbidity by worsening orthostatic hypotension and increasing fall risk. There is a scarcity of literature on this subject and there is no documentation of severe hypertension with rises in systolic blood pressure exceeding 50% of baseline ...
The purpose of this study is to test an interactive DVD intervention to encourage patients to stick to their blood pressure medication in order to achieve blood pressure control for African American patients. The intervention will convey health messages through personal patient stories who have dealt with or continue to struggle with high blood pressure. Hypothesis 1: At the end of 9 months a higher proportion of patients randomized to the intervention group will achieve app...
Preeclampsia and other high blood pressure disorders of pregnancy are a significant cause of both maternal and fetal complications of pregnancy. To date, there is no known "cure" for preeclampsia, but studies have shown that exercise may lower the risk of preeclampsia and high blood pressure disorders in pregnancy. Resistance training also lowers blood pressure, and may be easier to perform in a pregnant population, leading to higher compliance. The investigators propose to ...
The primary objective is to evaluate the antihypertensive efficacy of a fixed combination of Irbesartan/HydroChloroThiazide (CoAprovel) in Chinese moderate to severe hypertensive patients. The secondary objective is to get systolic blood pressure and diastolic blood pressure goal attainment rate from CoAprovel in Chinese hypertensive patients.
General anesthesia often reduces blood pressure whereby blood flow to the brain and other vital organs may become insufficient. Thus, medicine is often administered to maintain blood pressure but it is unclear at what level blood pressure should be aimed at during anesthesia. Thirty patients undergoing major abdominal surgery will be included. The study will start one hour after the start of surgery and lasts for approximately half an hour. The purpose of the study is to evalu...
Patients with advanced sarcoidosis often develop pulmonary hypertension. Pulmonary hypertension is a condition where the right side of the heart has to push the blood though the lungs at a higher pressure than normal. Since this pressure is higher, it is harder for the heart to pump the blood through the lungs to the left side of the body. If the blood can not get through the lungs, it can not get pumped through the rest of the body. This leads to weakness and shortness of brea...
Investigators plan to study blood pressure trends on days 3 to 6 of the postpartum period. Investigators will use a home blood pressure monitor that stays on the arm, and takes blood pressures hourly. Participants will record any symptoms that they feel are attributed to high blood pressure and pain medication use.
The study will compare agreement of invasive blood pressure measurements with non-invasive blood pressure measurements measured with a conical blood pressure and large standard upper arm rectangular cuff in super morbidly obese severely hypertensive (systolic blood pressure > 160 mmHg) parturients.
Validation of an existing algorithm designed to estimate blood pressure based on collected optical signals on patients against the reference method which is arterial catheter
NSAIDs, specifically cyclo-oxygenase (COX) inhibitors, are known to increase blood pressure over time in non-pregnant adults, but the effect of COX-inhibitors on blood pressure in the setting of preeclampsia have not been well studied. This study aims to assess the effect of avoiding COX-inhibitors on postpartum blood pressure control among women diagnosed with preeclampsia with severe features. Eligible women will be randomized to receive either acetaminophen or ibuprofen for ...
The aim of this research project is to find out whether a personalized definition of the lower blood pressure threshold based on the individual blood pressure profile by means of preoperative 24-hour blood pressure measurement can reduce organ damage (brain, kidney, heart) through reduced blood flow during surgery.
The investigators hypothesize that the Systolic Foot-to-Apex Time Interval (SFATI) method will be accurate for measurement of systolic blood pressure with marked arterial stiffness as seen in patients with severe renal impairment. Also that the presence of arterial calcifications only changes the agreement between the SFATI method and the reference method (auscultatory method) if the calcifications are very severe.
To develop adequate blood pressure (BP) lowering strategy after subacute ischemic stroke patients with symptomatic severe intracranial atherosclerosis. Primary hypothesis of this study is that aggressive BP control (lowering systolic BP below 120mmHg) will not increase the ischemic lesion volumes in hemisphere compared to modest BP lowering (lowering systolic BP below 140mmHg) in the patients with symptomatic severe intracranial atherosclerosis
To compare the effectiveness of advice versus two multicomponent lifestyle interventions to control blood pressure in participants with Stage 1 hypertension or higher than optimal blood pressure.
Patients with severe infection can develop very low blood pressure. There are many mechanisms leading to this,and one of them appears to involve a hormone called vasopressin. In children as compared to adults, the mechanism and response to low blood pressure are different for reasons that are not clear. One possibility is the difference in the production and/or response to vasopressin. Vasopressin has been become part of the treatment of children with low blood pressure in the ...
It had been shown that high percentage of severe preeclampsia patients got a high cerebral perfusion pressure (CPP) due to abnormal autoregulation of cerebral blood vessels with associated endothelial dysfunction and disrupted blood brain barrier. Moreover, patients with high CPP is more likely to present with headache compared to other patients with normal CPP.In this particular scenario, use of magnesium sulphate is associated with marked reduction of CPP and. hence preventio...
The Hypertension Canada Clinical Practice Guidelines for blood pressure measurement using AOBP recommend against any wait time prior to commencing the measurement. The recent AHA guidelines however call for a 5-minute rest first. In uncontrolled hypertension, AOBP is typically higher than the daytime readings from ambulatory blood pressure monitoring (ABPM), but this is not the case for patients with controlled hypertension.
This study will assess whether an intervention including mindfulness, dietary education, and smoking cessation can help African-American women of childbearing age (age 18-44) with hypertension or high blood pressure to lower their blood pressure. We propose to screen women of childbearing age for hypertension, and to invite women to participate in an intervention to reduce their blood pressure. We will track their perceived stress and their blood pressure levels over the next 6...
Purpose of this study is to assess the hypothesis that a strategy with acetylsalicylic acid (ASA) 100 mg/day, intensive blood pressure treatment (targeted systolic blood pressure below 120 mmHg), and a blood pressure measuring device reduces the risk of aneurysm rupture or growth compared with standard care (i.e. no ASA, blood pressure management according to standard blood pressure management, no blood pressure measuring device)
Contextualization: Exercise is a common triggers of bronchospasm in patients with asthma and healthy subjects. To prevent these symptoms frequently they have to use Short-Acting Beta2-Agonists. However, the cardiovascular effects of salbutamol during and after exercise remain poorly known. Objective: To evaluate the effect of salbutamol on heart rate and blood pressure during exercise in patients with moderate or severe asthma and healthy individuals. Methods: A randomi...
