AHT is responsible for high morbidity and mortality. In Portugal, according to PHYSA study, has overall prevalence of hypertension, in 2014, of 42.2% (44.4% in men, 40.2% in women). The progression of hypertensive heart disease involves myocardial fibrosis and changes in left ventricular geometry that precedes functional changes. Diastolic dysfunction is part of this continuum, and despite the growing recognition of its importance, it is generally undervalued because of the difficulty in its diagnosis and the absence of effective therapies. This reinforces the importance of finding alternative tests that provide important information for an initial assessment of diastolic function in hypertensive patients.
