A functional aspect of the vascular system is defined as physiology, which covers mostly cardiovascular, cerebrovascular, renovascular and pulmonary systems. Most functions with perfect homeostasis under coverage haemodynamics. This haemodynamics maintains a steady relationship between intravascular pressure (P), overall resistance (R) circulatory flow (F). To explore more unknown facts physiol...

We investigated the effects of atherosclerosis in carotid region on cerebral haemodynamics. A total 15 stenosis cases following NASCET criteria were modelled using patient-specific medical i...

BACKGROUND Whilst there is a presumption in medicine that ageing adversely affects cardiovascular function, it is unknown if resting haemodynamics are compromised in the elderly, and if so, to what degree. This study was intended to answer several questions; whether age-related changes in haemodynamics occur; whether there was a difference between the haemodynamics of ageing subjects with and w...

Improvement in exercise capacity may not be associated with significant changes in resting pulmonary haemodynamics. The present prospective study documented the relationships between improvement in 6-min walking distance (6MWD) and changes in resting and exercise pulmonary haemodynamics after treatment in patients with idiopathic pulmonary arterial hypertension (IPAH). A total of 42 IPAH patien...

Haemodynamic alterations in carotid and renal arteries are associated with the severity of target organ damage in patients with hypertension. Dietary habits, such as the Mediterranean diet, regulate blood pressure and oxidative stress, thus reduce the mortality rate due to cardiovascular diseases. In this study, our aim was to evaluate the reducing activity, antioxidant capacity and metal chela...

OBJECTIVES Determinant risk factors for developing protein losing enteropathy (PLE), including haemodynamics, remain unclear in patients after the Fontan operation. METHODS Our purpose was to characterize the serial PLE haemodynamics before and after the onset and to determine the risk factors based on the cardiac catheterization-based analysis. RESULTS Of 354 Fontan survivors who had under...

Intracardiac haemodynamics is crucial for normal cardiogenesis, with recent evidence showing valvulogenesis is haemodynamically dependent and inextricably linked with shear stress. Although valve anomalies have been associated with genetic mutations, often the cause is unknown. However, altered haemodynamics have been suggested as a pathogenic contributor to bicuspid aortic valve disease. Conve...

The most commonly used technique for lower limb surgeries is Spinal anesthesia, as it economical, easy, effective and has less complications. Adjuvants are added with local anaesthetics intrathecally. Opioids adjuvants to improves the quality of intraoperative analgesia prolongs postoperative analgesia. To observe compare effect intrathecal bupivacaine fentanyl butorphanol on onset duration sen...
