The investigators hypothesize that chronic insufficient sleep is associated with diminished endothelium-dependent nitric oxide-mediated vasodilation and endothelial tissue-type plasminogen activator release in adults with elevated blood pressure. Furthermore, the investigators hypothesize that the postulated diminishment in endothelial vasodilator and fibrinolytic function with insufficient sleep will be due, at least in part, to increased oxidative stress. Furthermore, increasing sleep duration and improving sleep quality will increase both endothelium-dependent nitric oxide-mediated vasodilation and endothelial tissue-type plasminogen activator release in adults with elevated blood pressure. Increases in endothelial vasodilator and fibrinolytic function will be due, at least in part, to reduced oxidative stress.

Our research question is: Are changes in sleep duration that occur naturally over school holidays associated with changes in blood pressure (BP) in sleep-deprived adolescents? In this stu...
The main purpose of this study is to learn about the influence of two different behavioral interventions (lasting 8 weeks) involving sleep for lowering blood pressure, and to study the mec...
Ambulatory blood pressure monitoring (ABPM) is an ideal tool for the diagnosis and evaluation of hypertension.However, ABPM frequently measures the tightening feeling and buzzing sound of ...
Macular edema remains a major cause of vision impairment in diabetic patients. Its pathogenesis is multifactorial and incompletely understood. Systemic factors seam to play a role in this ...
This research project will examine whether experimental sleep extension in children alters the neural and behavioral mechanisms by which short sleep is a risk factor for emotional/behavior...
From April to October 2018, we implemented a blood pressure measurement quality improvement project at our Hypertension Center. We aimed to compare blood pressure measured using routine, non-standardi...
Epidemiologic data increasingly supports sleep as a determinant of cardiovascular disease risk. Fewer studies have investigated the mechanisms underlying this relationship using objective sleep assess...
The efficacy and tolerability of intensive blood pressure lowering may vary by pulse pressure (systolic minus diastolic blood pressure).
Pulse transit time (PTT) derived by ECG and plethysmographic signal can be a promising alternative to invasive or oscillometry-based blood pressure (BP) monitoring in sleep laboratories because it doe...
We aimed to assess the feasibility of a text messaging intervention by determining the proportion of emergency department (ED) patients who responded to prompted home blood pressure (BP) self-monitori...
Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.
Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.
Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
Sleep disorders disrupt sleep during the night, or cause sleepiness during the day, caused by physiological or psychological factors. The common ones include snoring and sleep apnea, insomnia, parasomnias, sleep paralysis, restless legs syndrome, circa...
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
