Heart Rate Variability and Its Association With Symptom of Orthostatic Hypotension in Spinal Cord...
Spinal Cord InjuriesOrthostatic Hypotension1 moreIn this study, the SCI patients were sub-grouped on the basis of symptoms into symptomatic and asymptomatic groups and measured HRV during resting and tilt up tests to compare their cardiovascular autonomic functions.
Norepinephrine Prophylaxis for Postspinal Anesthesia Hypotension in Parturients With Preeclampsia....
Adverse EffectThe purpose of this study is to investigate the suitable infusion dose of norepinephrine for prophylaxis against postspinal anesthesia hypotension in parturients with preeclampsia undergoing cesarean section.
Hypotension Prediction Index: Correlations Between Invasive and Non-invasive Pressure Points.
HypotensionTo evaluate the clinical performance of the Hypotension Prediction Index obtained from the continuous, non-invasive Clear Sight monitor.
Perioperative Personalized Blood Pressure Management
Blood PressureIntraoperative Hypotension1 moreThe investigators propose a pilot trial to (1) proof the concept that defining the intraoperative mean arterial pressure (MAP) intervention threshold based on the mean nighttime MAP (assessed using preoperative automated blood pressure monitoring) results in clinically relevant (mean nighttime MAP ± 10 mmHg) different target values compared with using an absolute population-derived MAP intervention threshold of 65 mmHg (primary endpoint); (2) investigate if a personalized perioperative blood pressure management is feasibly in multi-center studies, especially if the target values can be sufficiently achieved (secondary endpoint); (3) study the impact of personalized perioperative blood pressure management on the incidence of myocardial injury after non-cardiac surgery (MINS) (exploratory endpoint); (4) study the impact of personalized perioperative blood pressure management on the incidence of acute kidney injury within the first three postoperative days according to the KDIGO (Kidney Disease: Improving Global Outcomes) definition without oliguric criteria (exploratory endpoint).
Head Out Water Immersion for Hemodynamic Stability During Dialysis
Intradialytic HypotensionImmersionImmersion to the neck before and during hemodialysis session may increase intravascular volume, potentiate the ability to ultrafiltrate excess water, with less symptoms of shock, muscle crumps etc. The aim of the present study is to compare blood volume, hemodynamic and endocrine parameters of chronic ESRD patients undergoing forth dialysis session in water immersion vs. control regular session.

The Effects of Nicotine Chewing Gum in Parkinson's Disease
Low Blood PressureParkinsons DiseaseThe objective of this experiment is: To determine if nicotine chewing gum will improve acute episodes of orthostatic hypotension in PD subjects.
A Phase 3 Study of LJPC-501 in Patients With Catecholamine-Resistant Hypotension
Catecholamine-resistant Hypotension (CRH)Distributive Shock2 moreThis is a Phase 3, double-blind, randomized study of LJPC-501 (angiotensin II) in adult patients diagnosed with catecholamine-resistant hypotension (CRH) conducted in multiple centers globally.
Chronic Angiotensin Converting Enzyme Inhibitors in Intermediate Risk Surgery
Hypotension on InductionPrimary research hypothesis: Patients who continue their chronic ACEI therapy up to and including the morning of a non-cardiac, non-vascular surgery will experience more intraoperative hypotension than those who transiently hold their chronic ACEI preoperatively. Secondary research hypothesis #1: Patients who continue their chronic ACEI up to and including the morning of a non-cardiac, non-vascular surgery will experience better postoperative control of hypertension than those who transiently hold their chronic ACEI preoperatively. Secondary research hypothesis #2: Patients who continue their chronic ACEI up to and including the morning of a non-cardiac, non-vascular surgery will experience less acute renal failure than those who transiently hold their chronic ACEI preoperatively. Secondary research hypothesis #3: In the subgroup of patients with a preoperative systolic blood pressure less than 110 mmHg, those who continue their chronic ACEI therapy up to and including the morning of a non-cardiac, non-vascular surgery will experience more intraoperative hypotension than those who transiently hold their chronic ACEI preoperatively. Secondary research hypothesis #4: In the subgroup of patients above the age of 64, those who continue their chronic ACEI therapy up to and including the morning of a non-cardiac, non-vascular surgery will experience more intraoperative hypotension than those who transiently hold their chronic ACEI preoperatively.
Acarbose, Postprandial Hypotension and Type 2 Diabetes
Type 2 DiabetesPostprandial HypotensionPostprandial hypotension carries a risk of significant morbidity and morbidity including syncope, falls, dizziness, fatigue, stroke and myocardial infarction. Current therapy consists of dietary manipulation (smaller meals) caffeine and octreotide injections all of which are suboptimal and poorly studied. The study hypothesis is that administration of Acarbose will decrease the drop in blood pressure and increase in heart rate in response to food in people with Type 2 diabetes. Acarbose suppresses postprandial glycemia be slowing digestion in the small intestine and delaying gastric emptying. This is a placebo-controlled cross over study involving 2 - 4 hour Meal Tests. During the meal tests heart rate, blood pressure, cerebral artery velocity will be measured. During one meal test subjects will receive Acarbose 50 mg po and during the other will receive placebo. Order of treatment assignment will be done in randomized fashion. A total of approximately 200 cc of blood will be drawn during each meal test.
