Abstract
An increase in the renal resistive index (RRI) in patients with essential hypertension (EH) predicts deterioration in renal function. In patients with EH, changes in hemodynamic parameters significantly affect the RRI. This study aimed to define changes in Ambulatory Blood Pressure Monitoring (ABPM) parameters that are significantly associated with a change in RRI in patients with EH. We evaluated ABPM and the RRI in 96 patients with EH without organ extrarenal changes at baseline and after two years of follow-up. The relationships between changes in ABPM parameters and the RRI over the period were evaluated. After two years of follow-up, the increase in RRI was consequential. Simultaneously, 24-h systolic blood pressure increased significantly and 24-h diastolic blood pressure decreased. In the whole group and in the group with calculated cystatin C clearance (eGFRcyst) >/=90 ml/min/1.73 m2, the change in RRI significantly negatively correlated with the change in the ratio of 24-h diastolic to systolic blood pressure (D/S ratio), but also with the change in 24-h pulse blood pressure. However, in patients with eGFRcyst>90 ml/min/1.73 m2, only the change in the 24-h D/S ratio significantly correlated with the change in RRI. Based on the backward stepwise regression analysis, the change in RRI was significantly dependent only on the change in 24-h D/S ratio and not on the change in 24-h pulse pressure. A change in the ratio of diastolic to systolic pressure better reflects a change in RRI than a change in pulse pressure.

Abstract
BACKGROUND The association between arterial stiffness (AS) and stable coronary artery disease (CAD) has been previously demonstrated. Whether increased arterial stiffness is associated with severe CAD in patients with acute coronary syndrome (ACS) is less explored. AIM We aim to investigate the relationship between AS parameters and the extent and severity of CAD in patients with ACS. METHODS The study population consisted of 275 patients with ACS. We measured various AS parameters including pulse wave velocity (PWV), augmentation index (AIx), and central pulse pressure (cPP). CAD extent and severity was evaluated by the number of vessels with greater than 70% stenosis. RESULTS The study population was predominantly men (77, 5%) with an average age of 56, 4±10, 6 years. One hundred and fifteen patients were diabetic and 97 were hypertensive. One hundred fifty patients were admitted for ST elevation myocardial infarction (54, 5%) and 37, 5% for non ST elevation myocardial infarction. Thirty six percent of patients had single vessel disease and 47, 6% of the study population had multivessel disease. At the multivariate analysis, a positive correlation was observed between the number of coronary vessels disease and PWV. PWV (OR=1,272; IC95% [1,090; 1,483]; p=0,002) and cPP (OR=1,071; IC95% [1,024; 1,121]; p=0,003) were also independent predictors of multivessel disease. CONCLUSION In patient with ACS, PWV is correlated with the extent of coronary artery disease, as measured by the number of vessels disease. PWV and cPP were also independent predictors of multivessel disease.

Abstract
Background Previous epidemiological evidence has identified many risk factors for coronary artery disease (CAD). Pulse pressure (PP) was reported to be associated with CAD. However, more attention was paid to aortic PP than to brachial PP. This cross-sectional study aimed to investigate the direct relationship between brachial PP and the presence and extent of CAD in stable angina patients. Methods We recruited a total of 1118 consecutive patients with stable chest pain suspected of CAD. After screening with exclusion criteria, 654 patients were finally included in our study. Every patient underwent both blood pressure measurement and selective coronary angiography. Univariate and multivariate analysis were performed to analyze the association between PP and the presence and extent of CAD. Results This study revealed that brachial PP was an independent correlate of multivessel CAD. In multivariate generalized linear regression model, increasing brachial PP (per 1 mmHg) were associated with the increased number of diseased vessels (β = 0.01, SE = 0.00, P < 0.0001). Binary logistic regression analysis further confirmed this association. The risk of multivessel CAD increased significantly in patients with brachial PP ≥ 60 mmHg (OR = 1.69, 95% CI = 1.14–2.48, P = 0.0084) and as per 1 mmHg increased in brachial PP (OR = 1.02, 95% CI = 1.01–1.03, P = 0.0002), independent of age, gender, body mass index (BMI), smoking, diabetes, hypercholesterolemia and creatinine (Cr). This association was still of statistical significance in subgroup analysis of hypertension and diabetes. Conclusion Increasing brachial PP was significantly and independently associated with increased risk of multivessel coronary disease in stable angina patients. The association of brachial PP with CAD was more pronounced in hypertension group than in non-hypertension one.

Abstract
This study was performed to investigate the association between brachial pulse pressure (PP) and the presence/extent of obstructive coronary artery disease (CAD) in men and women. Study data were obtained from a nation-wide registry composed of 632 patients (173 men and 459 women, 58.1±10.5 years) with suspected CAD who underwent invasive coronary angiography. PP was higher in patients with obstructive CAD (≥50% stenosis) than those without CAD in both sexes (P=.032 in men; P<.001 in women). However, PP increased proportionally with the increasing number of obstructed coronary arteries in women (P<.001) but not in men (P=.070). Multiple logistic-regression analyses demonstrated that higher PP (≥50.5 mm Hg) was an independent factor for determining obstructive CAD even after controlling for potential confounders in women (odds ratio, 2.83; 95% confidence interval, 1.40-5.73; P=.004). These results were consistent in 173 selected women matched with 173 men based on age and CAD severity. In conclusion, the association between brachial PP and obstructive CAD was more pronounced in women than in men. Brachial PP can be a simple and useful indicator of CAD especially in women.

Abstract
BACKGROUND AND AIM The objective of this research was to determine whether invasively measured central pulse pressure (PP) in patients indicated for coronarography is associated with two common polymorphisms in the ACE2 region (rs4646156 and rs4646174). METHODS A total of 307 patients were enrolled in the study. The genotyping of both SNPs from peripheral blood samples was carried out using 5'exonuclease (Taqman®) chemistry on the ABI Prism® 7000 system (Applied Biosystems, Foster City, CA, USA). RESULTS In both polymorphisms, the associations with central PP were found to be highly significant when all five possible genotypes in the population had been compared (p = 0.0001). In men, there was a higher incidence of previous myocardial infarction in G0 genotype carriers of rs54646174 (OR ratio = 7; p = 0.005). The AA genotype of rs4646156 had a 7.81× higher risk of severe angina pectoris in women (OR = 7.81, p = 0.05). A significant difference in allelic frequency of ACE2rs4646174 was found between women with and without significant stenoses of the circumflex branch of the left coronary artery. CONCLUSION More research into the role of ACE2 genetic variability in PP regulations is necessary for more detailed physiological and pathophysiological comprehension of PP regulation.
