BACKGROUND: Hypertension after thoracic endovascular aortic repair (TEVAR) is a medical complication not widely investigated. The aim of the study was to test the hypothesis that TEVAR in young patients suffering from thoracic aortic transection alters pulse wave velocity (PWV) and reflected wave velocity and induces arterial hypertension. METHODS: The ...

We report the case of a 34-year-old male patient who presented with generalized weakness, poorly controlled hypertension, nocturnal hypertension spikes, and morning headaches. The history of resistant hypertension, obesity, enlarged neck size, and loud irregular snoring strongly suggested obstructive sleep apnea (OSA). To exclude other possible causes of resistant hypertension, ...

Signals reflecting the metabolic and circulatory status of an injured central nervous system are normally corrupted systematically. The patient is part of a therapeutic control-loop and the signals acquired are rather determined by the quality of control (stationarity of signals) than by the underlying pathological process. To verify the control-loop ...

We designed and implemented a prototype software tool to provide information about hypertension, video instructions on correct home blood pressure measurement technique ...

Repetitive skin trauma and reduced pressure pain sensation are necessary components of plantar ulcer risk in patients with diabetic neuropathy. The diagnostic value of measuring pressure nociception to detect ulcer risk is, however, unknown. Instead, measuring the vibration perception threshold (VPT) by 64 Hz graduated Rydel-Seiffer tuning fork has become ...

Combination therapy is recommended for patients with blood pressure (BP) significantly above goal by recent consensus guidelines around the globe. The use of angiotensin II receptor blockers (ARBs) alone or in combination with a thiazide diuretic is a preferred treatment strategy due to both efficacy and safety considerations. However, there ...

Pressure, from lying or sitting on a particular part of the body results in reduced oxygen and nutrient supply, impaired drainage of waste products and damage to cells. If a patient with an existing pressure ulcer continues to lie or bear weight on the affected area, the tissues become depleted ...

Patients with diastolic dysfunction may have a disproportionate degree of elevation in pulmonary pressure, particularly in the elderly. Higher pulmonary vascular resistance in the elderly patients with heart failure but preserved ejection fraction suggests that beyond the post-capillary contribution of pulmonary venous congestion, a pre-capillary component of pulmonary arterial hypertension ...
