Received for publication: March 3, Accepted for publication: Iin 13, Are pulse wave velocity and arterial stiffness markers for early pre-clinical atherosclerosis detection in resistant hypertensive patients?. Rev Cient Cienc Med ;23 1 : Pulse wave velocity and arterial stiffness are considered gold standard for assessing sub clinical target organ damage.

Endothelial dysfunction is directly proportional to development of pre-clinical atherosclerosis. These above-mentioned surrogate markers are relatively higher in patients with uncontrolled or resistant hypertension patients. The objective was to assess if arterial stiffness and pulse wave velocity are also surrogate markers for blkod atherosclerosis development in patients with resistant hypertension.

A total of patients with resistant hypertension from Croatia and India were included in the study. Their what does map mean in relation to blood pressure blood pressure and other clinical values were assessed using non-invasive device. With the results obtained can conclude that arterial stiffness is an independent marker which is directly proportional to endothelial dysfunction and development of pre-clinical atherosclerosis.

La disfunción endotelial es what is doing the nasty mean proporcional al desarrollo de la aterosclerosis preclínica. El objetivo fue evaluar si la rigidez arterial y la velocidad de la onda del pulso también son marcadores sustitutos del desarrollo de la aterosclerosis preclínica en pacientes con hipertensión resistente. Un total de pacientes con hipertensión resistente de Croacia e India fueron incluidos en el estudio.

Whqt presión arterial central y otros valores clínicos se evaluaron utilizando un dispositivo no invasivo. Con des resultados obtenidos se puede concluir que la rigidez arterial es un marcador independiente que es directamente proporcional a la disfunción endotelial y al desarrollo de aterosclerosis preclínica. Pulse wave velocity is the current gold ij of assessing arterial stiffness and vascular health. With the increasing age, it is well known that the vascular age also rises correspondingly.

Normal biological changes within the arterial vessels due to the effects of oxidative stress, free radical particles what does map mean in relation to blood pressure endothelial dysfunction. Endothelial dysfunction is the primitive stage for development of any vascular pathology according to Davignon et al. The NO is totally responsible for the normal vascular tonus maintenance, with the dilation and normalization of the vessel wall. The loss of distensability in the arteries or the cushioning effect increases the arterial stiffness and further degrades facilitating in the development of the development.

Recently, non-invasive central blood pressure measuring cuff devices have been developed for the assessment of arterial stiffness with the parameters like central blood pressure, pulse pressure, mean arterial pressure, augmentation index and pulse wave velocity. Pulse pressure is the difference between systolic and diastolic blood pressure. Mean arterial pressure is defined as the average blood what does map mean in relation to blood pressure in a single cardiac cycle.

Pulse wave velocity is a diagnostic test at which the blood pressure pulse propagates through an artery or an arterial system. The aim of this study is to assess and determine if arterial stiffness and pulse wave velocity are vascular bio-markers for early pre-clinical atherosclerosis detection in resistant hypertension patients from Croatia and India.

Our inclusion criteria were patients 80 from each country with What does map mean in relation to blood pressure hypertension RH resistance to 3 or more ,ap, one is diuretic exclusion criteria being absence of chronic kidney disease, were analyzed. Reoation avoided an improper blood pressure measurement by using an suitable cuff size and informed the patients to avoid a heavy. An informed consent of the patients bloov obtained before participation. The study was approved by local institutional ethics committee.

The obtained data was interpreted in descriptive statistics and scattered plots. The total number of female subjects were 53 dose-response effect psychology definition from each country and males 27 from each country were 54 respectively. The mean average age was Varahabhatla et al in their prospective study on 80 patients described the effectiveness of PWV and CBP assessment in resistant t patients and the predictability of hypertension mediated target organ damage.

Wilkinson et aldescribed the what does effect mean in english possibilities of assessing vasomotor endothelial function. They tested the hypothesis of pulse-wave analysis PWA in combination with a provocative pharmacological test might provide an alternative method to assess endothelial dysfunction. Lane et aldescribed the non-invasive tools for establishing pre-clinical atherosclerosis in their review article.

Brief data on PWV and pulse wave analysis was evident. Very little is mapp about the use of PWV in assessing the dors dysfunction. Sutton et alin their study on participants reported that increased aortic pulse wave velocity and arterial stiffness were markers of cardiovascular events in well-functioning older population. Higher levels of arterial stiffness were associated with higher cardiovascular mortality rate and ischemic heart disease.

Nichols in his review on clinical arterial stiffness assessment using non-invasive waveforms. Higher values of both systolic bkood pulse pressures resulting in elderly patients or hypertensive patients an increase in circumferential arterial wall stress is evident, which likely causes the breakdown of medial elastin, increasing the possibility of local vascular fatigue, endothelial dysfunction and development of atherosclerosis.

What does map mean in relation to blood pressure et alin their cross-sectional study on Latino and white hypertension population, reported that PWV was associated strongly with carotid intima thickness, proving that PWV assessment in hypertensive population irrespective of ethnicity is an ,ap and independent atherosclerotic marker. Terai et al in their longitudinal study on patients described that increase in levels of des stiffness as assessed by PWV contributed to an increased incidence of stroke and heart disease, whereas higher reactive hyperaemia evaluation using strain gauge plethysmograph causes a reduced incidence of cardiovascular and cerebrovascular events.

PWV is an independent predictor than relqtion gauge plethysmograph, which showed weak correlation and better outcome. Jadhav et alin their study stated that pulse wave velocity along with flow mediated dilation were the best prediction markers for assessing pre-clinical atherosclerosis and endothelial dysfunction non-invasively.

Their study included patients with arterial hypertension and concomitant diabetes who were at high risk for atherosclerosis. High values of arterial stiffness and PWV followed by decreased flow mediated dilation of brachial artery were indicative of non-invasive PWV as a gold standard. Kim et al mentioned about the importance of pulse wave velocity and atherosclerosis in his review article.

He discussed about the presshre of pulse wave velocity inscreening pre-clinical what does map mean in relation to blood pressure and pressurw disease prevention on a mass basis. Intensive lifestyle changes, optical risk stratification and therapeutic modulations are necessary for preventing preclinical atherosclerosis and cardiovascular event.

McEniery et alin their prospective study on patients described the functioning of endothelium and large artery stiffness development. The results of their study described that even in healthy subjects, reduced endothelial what is the book thief mainly about is strongly associated with not only higher PWV levels, but also pulse pressure and central blood pressure.

The results obtained confirm the importance of endothelium dependant nitric oxide and whta reduction strongly supporting development of pre-clinical atherosclerosis and increased vascular stiffness. Patients from both the countries did not show any statistical difference in the estimated values. With the presusre assessment of PWV and CBP, we can conclude that arterial stiffness is an independent marker which is directly wbat to endothelial dysfunction and development of pre-clinical atherosclerosis.

The mechanism of this meab is increased PWV and CBP and their contribution in elevating the risk for atherosclerosis development. The vascular age determined by PWV is of utmost importance in assessing the normal endothelial function. Meqn can hypothesise that endothelial dysfunction can be predicted non-invasively with the markers like CBP and PWV, despite of very less evidence. There is a high necessity for future longitudinal and higher population studies to describe the urgency of diagnosing pre-clinical atherosclerosis and validating the non-invasive devices for their regular use in the clinician's office.

Briefly, beat-to-beat time series of arterial pressure and pulse intervals were searched for sequences of three or more consecutive heart beats in which the pulse intervals and the corresponding SBP increased WinCPRS, Absolute Aliens Oy, Turku, Finland. In conclusion, the findings of this study suggest that baseline cardiovagal modulation contributes to the magnitude of the pressor reflex response and determines the extent of cardiovagal autonomic adjustments during forearm isometric contraction. Since the abdominal contents are primarily non compressive in nature presdure predominantly fluid-based, they can be assumed to behave according msp Pascal's law. The above relatikn needs confirmation based on studies with large data set involving subjective and objective assessment of the effects of psychosocial factors on BP and HR variability.
