Hypertension urgency and emergency represents a challenging condition in which clinicians should determine the assessment and/or treatment of these patients. Whether the elevation of blood pressure (BP) levels is temporary, in need of treatment, or reflects a chronic hypertensive state is not always easy to unravel. Unfortunately, current guidelines provide few recommendations concerning the diagnostic approach and treatment of emergency department patients presenting with severe hypertension. Target organ damage determines: the timeframe in which BP should be lowered, target BP levels as well as the drug of choice to use. It's important to distinguish hypertensive emergency from hypertensive urgency, usually a benign condition that requires more likely an outpatient visit and treatment.
•Data regarding possible differences in congestion in HFrEF and HFpEF are scant.•Repeated lung and IVC ultrasound allow a dynamic evaluation of pulmonary and intravascular congestion.•HFrEF patients ...showed greater pulmonary congestion than HFpEF both at admission and after diuretic therapy.•In HFrEF diuretic therapy determined a greater reduction of intravascular congestion.•In HFrEF residual intravascular congestion independently predicted readmission/death at 90 days.
: To evaluate pulmonary and intravascular congestion at admission and repeatedly during hospitalization for acute decompensated heart failure (ADHF) in HFrEF and HFpEF patients using lung (LUS) and inferior vena cava (IVC) ultrasound.
: Three-hundred-fourteen patients (82±9 years; HFpEF =172; HFrEF=142) admitted to Internal Medicine wards for ADHF were enrolled in a multi-center prospective study. At admission HFrEF presented higher indexes of pulmonary and intravascular congestion (LUS-score: 0.9 ± 0.4 vs 0.7 ± 0.4; p<0.01; IVC end-expiratory diameter: 21.6 ± 5.1 mm vs 20±5.5 mm, p<0.01; IVC collapsibility index 24.4 ± 17.4% vs 30.9 ± 21.1% p<0.01) and higher Nt-proBNP values (8010 vs 3900 ng/l; p<0.001). At discharge, HFrEF still presented higher B-scores (0.4 ± 4 vs 0.3 ± 0.4; p = 0.023), while intravascular congestion improved to a greater extent, thus IVC measurements were similar in the two groups. No differences in diuretic doses, urine output, hemoconcentration, worsening renal function were found. At 90-days follow up HF readmission/death did not differ in HFpEF and HFrEF (28% vs 31%, p = 0,48). Residual congestion was associated with HF readmission/death considering the whole population; while intravascular congestion predicted readmission/death in the HFrEF, no association between sonographic indexes and the outcome was found in HFpEF.
: Serial assessment of pulmonary and intravascular congestion revealed a higher burden of fluid overload in HFrEF and, conversely, a greater reduction in intravascular venous congestion with diuretic treatment. Although other factors beyond EF could play a role in congestion/decongestion patterns, our data may be relevant for further phenotyping HF patients, considering the importance of decongestion optimization in the clinical approach.

Hypertensive emergencies (HE) and urgencies (HU) are frequent causes of patients referral to Emergency Department (ED) and the approach may be different according to local clinical practice. Our aim was to explore awareness, management, treatment and counselling after discharge of HE and HU in Italy, by mean of an on-line survey. The young investigator research group of the Italian Society of Hypertension developed a 23-item questionnaire spread by e-mail invitation to the members of Italian Scientific societies in the field of Hypertension. 665 questionnaires were collected from EDs, Emergency and Urgency Medicine, Cardiology or Coronary Units, Internal Medicines, Intensive care, Stroke units. Symptoms considered suspicious of acute organ damage were: chest pain (89.0%), visual disturbances (89.8%), dyspnoea (82.7%), headache (82.1%), dizziness (52.0%), conjunctival haemorrhages (41.5%), tinnitus (38.2%) and epistaxis (34.4%). Exams more frequent prescribed were: electrocardiogram (97.2%), serum creatinine (91.4%), markers of cardiomyocyte necrosis (66.2%), echocardiography (65.1%). The use of intravenous or oral medications to treat HEs was 94.7% and 3.5%, while for HUs 24.4% and 70.8% respectively. Of note, a surprisingly high percentage of physicians (22 % overall, 24.5% in North Italy) used to prescribe sublingual nifedipine. After discharge, home blood pressure monitoring and general practitioner re-evaluation were more frequently suggested, while ambulatory blood pressure monitoring and hypertension specialist examination were less prescribed. The differences observed across the different macro-areas, regarded prescription of diagnostic test and drug administration. This survey depicts a complex situation of shades and lights in the real-life management of HE and HU in Italy.
Background
Preoperative portal vein embolization (PVE) is frequently used to improve future liver remnant volume (FLRV) and to reduce the risk of liver failure after major liver resection.
Objective
...This paper aimed to assess postoperative outcomes after PVE and resection for suspected perihilar cholangiocarcinoma (PHC) in an international, multicentric cohort.
Methods
Patients undergoing resection for suspected PHC across 20 centers worldwide, from the year 2000, were included. Liver failure, biliary leakage, and hemorrhage were classified according to the respective International Study Group of Liver Surgery criteria. Using propensity scoring, two equal cohorts were generated using matching parameters, i.e. age, sex, American Society of Anesthesiologists classification, jaundice, type of biliary drainage, baseline FLRV, resection type, and portal vein resection.
Results
A total of 1667 patients were treated for suspected PHC during the study period. In 298 patients who underwent preoperative PVE, the overall incidence of liver failure and 90-day mortality was 27% and 18%, respectively, as opposed to 14% and 12%, respectively, in patients without PVE (
p
< 0.001 and
p
= 0.005). After propensity score matching, 98 patients were enrolled in each cohort, resulting in similar baseline and operative characteristics. Liver failure was lower in the PVE group (8% vs. 36%,
p
< 0.001), as was biliary leakage (10% vs. 35%,
p
< 0.01), intra-abdominal abscesses (19% vs. 34%,
p
= 0.01), and 90-day mortality (7% vs. 18%,
p
= 0.03).
Conclusion
PVE before major liver resection for PHC is associated with a lower incidence of liver failure, biliary leakage, abscess formation, and mortality. These results demonstrate the importance of PVE as an integral component in the surgical treatment of PHC.
The presence of structural alterations in the microcirculation may be considered an important mechanism of organ damage; however, it is not currently known whether structural alterations of small ...arteries may predict fatal and nonfatal cardiovascular events.
One hundred twenty-eight patients were included in the present study. There were 59 patients with essential hypertension, 17 with pheochromocytoma, 20 with primary aldosteronism, 12 with renovascular hypertension, and 20 normotensive patients with non-insulin-dependent diabetes mellitus. All subjects were submitted to a biopsy of subcutaneous fat. Small resistance arteries were dissected and mounted on an isometric myograph, and the tunica media-to-internal lumen ratio (M/L) was measured. The subjects were reevaluated after an average follow-up time of 5.4 years. Thirty-seven subjects had a documented fatal or nonfatal cardiovascular event (5.32 events/100 patients per year). In the subcutaneous small arteries of subjects with cardiovascular events, a smaller internal diameter and a clearly greater M/L was observed. Our subjects were subdivided according to the presence of an M/L greater or smaller than the mean and median values observed in the whole population (0.098) or mean value +2 SD of our normal subjects (0.11). Life-table analyses showed a significant difference in event-free survival between the subgroups. Cox's proportional hazard model, considering all known cardiovascular risk factors, indicated that only pulse pressure (P=0.009) and M/L (P<0.0001) were significantly associated with the occurrence of cardiovascular events.
Our results strongly indicate a relevant prognostic role of structural alterations in small resistance arteries of a high-risk population.
ABSTRACT—Left ventricular (LV) mass and geometry predict risk for cardiovascular events in hypertension. Regression of LV hypertrophy (LVH) may imply an important prognostic significance. The ...relation between changes in LV geometry during antihypertensive treatment and subsequent prognosis has not yet been determined. A total of 436 prospectively identified uncomplicated hypertensive subjects with a baseline and follow-up echocardiogram (last examination 72±38 months apart) were followed for an additional 42±16 months. Their family doctor gave antihypertensive treatment. After the last follow-up echocardiogram, a first cardiovascular event occurred in 71 patients. Persistence of LVH from baseline to follow-up was confirmed as an independent predictor of cardiovascular events. Cardiovascular morbidity and mortality were significantly greater in patients with concentric (relative wall thickness ≥0.44) than in those with eccentric geometry (relative wall thickness <0.44) in patients presenting with LVH (P =0.002) and in those without LVH (P =0.002) at the follow-up echocardiogram. The incidence of cardiovascular events progressively increased from the first to the third tertile of LV mass index at follow-up (partition values 91 and 117 g/m), but for a similar value of LV mass index it was significantly greater in those with concentric geometry (OR4.07; 95% CI1.49 to 11.14; P =0.004 in the second tertile; OR3.45; 95% CI1.62 to 7.32; P =0.001 in the third tertile; P <0.0001 in concentric versus eccentric geometry). Persistence or development of concentric geometry during follow-up may have additional prognostic significance in hypertensive patients with and without LVH.
Abstract Background and aims The independent role of serum uric acid (SUA) as a marker of cardio-renal risk is debated. The aim of this study was to assess the relationship between SUA, metabolic ...syndrome (MS), and other cardiovascular (CV) risk factors in an Italian population of hypertensive patients with a high prevalence of diabetes. Methods and results A total of 2429 patients (mean age 62 ± 11 years) among those enrolled in the I-DEMAND study were stratified on the basis of SUA gender specific quartiles. MS was defined according to the NCEP-ATP III criteria, chronic kidney disease (CKD) as an estimated GFR (CKD-Epi) <60 ml/min/1.73 m2 or as the presence of microalbuminuria (albumin-to-creatinine ratio ≥2.5 mg/mmol in men and ≥3.5 mg/mmol in women). The prevalence of MS, CKD, and positive history for CV events was 72%, 43%, and 20%, respectively. SUA levels correlated with the presence of MS, its components, signs of renal damage and worse CV risk profile. Multivariate logistic regression analysis revealed that SUA was associated with a positive history of CV events and high Framingham risk score even after adjusting for MS and its components (OR 1.10, 95% CI 1.03–1.18; P = 0.0060; OR 1.28, 95% CI 1.15–1.42; P < 0.0001). These associations were stronger in patients without diabetes and with normal renal function. Conclusions Mild hyperuricemia is a strong, independent marker of MS and high cardio-renal risk profile in hypertensive patients under specialist care. Intervention trials are needed to investigate whether the reduction of SUA levels favorably impacts outcome in patients at high CV risk.
Abstract Purpose Screening of Cushing Syndrome (CS) and Mild Autonomous Cortisol Secretion (MACS) in hypertensive patients is crucial for proper treatment. The aim of the study was to investigate ...screening and management of hypercortisolism among patients with hypertension in Italy. Methods A 10 item-questionnaire was delivered to referral centres of European and Italian Society of Hypertension (ESH and SIIA) in a nationwide survey. Data were analyzed according to type of centre (excellence vs non-excellence), geographical area, and medical specialty. Results Within 14 Italian regions, 82 centres (30% excellence, 78.790 patients during the last year, average 600 patients/year) participated to the survey. Internal medicine (44%) and cardiology (31%) were the most prevalent medical specialty. CS and MACS were diagnosed in 313 and 490 patients during the previous 5 years. The highest number of diagnoses was reported by internal medicine and excellence centres. Screening for hypercortisolism was reported by 77% in the presence of specific features of CS, 61% in resistant hypertension, and 38% in patients with adrenal mass. Among screening tests, the 24 h urinary free cortisol was the most used (66%), followed by morning cortisol and ACTH (54%), 1 mg-dexamethasone suppression test (49%), adrenal CT or MRI scans (12%), and late night salivary cortisol (11%). Awareness of referral centres with expertise in management of CS was reported by 67% of the participants, which reduced to 44% among non-excellence centres. Conclusions Current screening of hypercortisolism among hypertensive patients is unsatisfactory. Strategies tailored to different medical specialties and type of centres should be conceived.
It has been proposed that several neurohumoral factors may be involved in the genesis of vascular structural changes (remodeling or hypertrophy) frequently observed in essential hypertension. ...Therefore, in this study we investigated vascular structural alterations of subcutaneous small resistance arteries in patients with secondary forms of hypertension. The study included 70 participants11 with pheochromocytoma, 13 with primary aldosteronism, and 17 with renovascular hypertension; 13 normotensive subjects and 16 patients with essential hypertension served as controls. All subjects were submitted to a biopsy of subcutaneous fat. Small resistance arteries were dissected and mounted on a micromyograph, and media-lumen ratio, media thickness, remodeling index, and growth index were evaluated. Endothelial function was evaluated according to the dose-response curve to acetylcholine. In patients with either primary aldosteronism or renovascular hypertension, a marked increase in media-lumen ratio was observed, whereas in patients with pheochromocytoma, the extent of vascular structural alterations was similar to that observed in patients with essential hypertension. The increase in media-lumen ratio in patients with essential hypertension and with pheochromocytoma was mainly due to vascular remodeling (remodeling index, 93% to 94%), whereas in patients with renovascular hypertension, there was vascular growth (remodeling index, 70%; growth index, 53%). Patients with primary aldosteronism had an intermediate pattern compared with the other two forms of secondary hypertension. An evident impairment of endothelial function was observed in all four hypertensive groups. In conclusion, the renin-angiotensin-aldosterone system seems to be more powerful than the adrenergic system in inducing vascular growth. (Hypertension. 1996;28:785-790.)
