Objectives: To estimate the trend in arterial hypertension's prevalence, awareness, treatment, and control in Romania, starting from the latest national survey Study for the Evaluation of Prevalence of Hypertension and Cardiovascular Risk in Romania III that has a crucial importance for the development of prevention strategies at national level. Methods: A representative sample of 1970 Romanian adults (mean age 48.38 years, age range 18–80 years, 52.5% women, 72.58% response rate), was enrolled. During the two study visits, three blood pressure (BP) measurements were performed at 1-min interval. Hypertension was defined as study SBP at least 140 mmHg and/or study DBP at least 90 mmHg at both study visits or previously diagnosed hypertension, regardless of BP values. BP control was defined as SBP less than 140 mmHg and DBP less than 90 mmHg in hypertensive patients. Results: General hypertension prevalence is 45.1% (19.1% newly diagnosed hypertension, 80.9% awareness of hypertension), increasing with age, regardless of sex and area of residence. Although the majority (72.2%) of hypertensive patients were treated (51.9% with two or more drugs), only 30.8% of them had controlled BP values. Following the evolution from the last 11 years, it is expected that in 2020 the prevalence of hypertension to be up to 44%, the awareness up to 96.2%, treatment of hypertension up to 83.7%, and BP control up to 36.6%. Conclusion: Hypertension's prevalence in Romania is on the rise despite the increase in awareness, treatment, and control. Possible explanations of this trend might be the increasing incidence of unhealthy lifestyle and diet, including high salt intake, and a general increase in the prevalence of obesity, diabetes mellitus, and dyslipidemia.

East European countries have reported high prevalence of Arterial Hypertension (AHT). In order to investigate the data for Romania, we firstly performed a national survey—the Study for the Evaluation of Prevalence of Hypertension and Cardiovascular Risk in Adult Population in Romania (SEPHAR). A representative population was selected using stratified proportional sampling, including 2017 adult subjects,≥18years old. The general prevalence of AHT was 44,92%, higher in men (50,17%) than in women (41,11%) (P<.0001) and predominant in rural areas (49,47%) in comparison to the urban ones (41,58%) (P<.02). AHT awareness attended 44,26%, rising with age, significantly lower in men (34,58%) than in women (52,8%) (P<.0006). We have found a 38,85% proportion of treated hypertensive persons, worse for men (30,11%) then for women (46,56%) (P<.003). The rate of AHT control was 19,88%, with no significant differences between gender. In conclusion, we estimated for Romania a high prevalence of AHT, a level of awareness and treatment lower than in many European countries and a rate of treatment control at the inferior limit of the European average. Males, characterized by a higher prevalence of AHT, were also less aware and less treated than women.

Initially, the renal resistive index (RRI) was investigated with the aim of improving diagnosis in kidney diseases, but this goal was not met. Recently, many papers have highlighted the prognostic significance of the RRI in chronic kidney disease: specifically, in estimating the revascularization success of renal artery stenoses or the evolution of the graft and the recipients in renal transplantation. Moreover, the RRI has become significant in the prediction of acute kidney injury in critically ill patients. Studies in renal pathology have revealed correlations of this index with parameters of systemic circulation. The theoretical and experimental premises of this connection were then reconsidered, and studies analyzing the link between RRI and arterial stiffness, central and peripheral pressure, and left ventricular flow were conducted with this purpose. Many data currently indicate that RRI is influenced more by pulse pressure and vascular compliance than by renal vascular resistance—assuming that RRI reflects the complex interplay between systemic circulation and renal microcirculation and should be considered a marker of systemic cardiovascular risk beyond its prognostic relevance for kidney disease. In this review, we overview the clinical research that reveals the implications of RRI in renal and cardiovascular disease.

To present the current epidemiologic situation regarding hypertension's prevalence and control in Romania's adult population (revealed by SEPHAR II survey results) and to evaluate their tendency during the last 7 years (by comparing with the SEPHAR I survey results). The two SEPHAR cross-sectional national surveys were conducted on a representative sample for the Romanian adult population (SEPHAR I: 2017 individuals aged 18-85 years, 45% response rate, SEPHAR II: 1975 individuals aged 18-80 years, 69% response rate), by means of questionnaire interview, blood pressure (BP) and anthropometric measurements during two study visits. Hypertension was defined as SBP at least 140 mmHg and/or DBP at least 90 mmHg at both study visits or previously diagnosed hypertension under current treatment. Controlled BP was defined as SBP less than 140 mmHg and DBP less than 90 mmHg in currently treated hypertensive individuals. Prevalence of hypertension in Romanian is 40.41%, awareness of hypertension is 69.55%, with 59.15% hypertensive individuals under current treatment with a control rate of 25%. In the last 7 years, there has been a 10.7% decrease in hypertension's prevalence together with an increase by 57% in awareness of hypertension and an increase by 52% in treatment of hypertension, leading to almost doubling of the hypertension's control rate in all hypertensive individuals. Although in the last 7 years, the tendency of hypertension's prevalence seems to be a descending one with an increasing trend in awareness, treatment and control of this condition, hypertension in Romania at this time still remains an 'unsolved equation'.

Background: In this study, we aimed to describe the impact of MBs on atherosclerosis and survival, in patients with coronary artery disease (CAD). Methods: We retrospectively studied 1920 consecutive patients who underwent conventional coronary angiography for suspected CAD. Atherosclerotic load (AL), defined as the sum of degrees of stenosis, and general atherosclerotic load (GAL), representing the sum of AL, were compared between patients with MB and a control group without MB; patients in these groups were similar in age and sex. We assessed survival at 10 years after the last enrolled patient. Results: Prevalence of MB was 3.96%, predominantly in the mid-segment of left anterior descendent artery (LAD). In the presence of MB, GAL was lower (158.1 ± 93.7 vs. 205.3 ± 117.9, p = 0.004) with a lesser AL in the proximal (30.3 ± 39.9 vs. 42.9 ± 41.1, p = 0.038) and mid-segments (8.1 ± 20.0 vs. 25.3 ± 35.9, p < 0.001) of LAD. Based on a Multinominal Logistic Regression, we found that the presence of MB on LAD (regardless of its location on this artery) is a protective factor against atherosclerotic lesions, decreasing the probability of significant stenosis, especially of those ≥70%, on the entire artery (B −1.539, OR 4660; 95% CI = 1.873–11.595, p = 0.001) and on each of its segments as well: proximal LAD (B −1.275, OR 0.280; 95% CI = 0.015–5.073; p = 0.038), mid-LAD (B −1.879, OR 6.545; 95% CI = 1.492–28.712; p = 0.013) and distal LAD (B −0.900, OR 2.459, 95% CI = 2.459–2.459, p = 0.032). However, 10-year survival was similar between groups (76.70% vs. 74.30%, p = 0.740). Conclusion: The presence of MB on LAD proved to be a protective factor against atherosclerosis for the entire artery and for each of its segments, but it does not influence long-term survival in patients with CAD.
