Hypertension is a major cardiovascular (CV) risk factor and elevated blood pressure poses a significant burden for the whole CV hemodynamics. Along the last decades different techniques and resources have been developed, including ultrasound´s M-mode and B-mode, spectral Doppler, tissue Doppler and color Doppler. Techniques from newer resources as speckle ...

Hyperactivity of sympathetic nervous system is one of the main mechanisms to play a role in the pathophysiology of hypertension. Its high prevalence and the low rates of adequate blood pressure control with pharmacological treatment brought interest to novel therapeutical strategies. Percutaneous renal sympathetic denervation emerged as an effective and ...

Perioperative hypertension has been shown to be a risk factor for the development of perioperative morbidity and mortality. The time spent outside acceptable blood pressure ranges, in a state of hypertension or hypotension, is correlated with the incidence of stroke, acute coronary syndrome, renal dysfunction, and death. The ideal perioperative ...
