Cutaneous microcirculation reactivity in patients with arterial hypertension, taking into account intake of anti-hypertensive drugs.

The aim of the study was to assess the reactivity of the cutaneous microcirculation in patients with arterial hypertension (AH), taking into account the intake of anti-hypertensive drugs, using laser doppler flowometry (LDF) and the post-occlusive reactive hyperaemia (PORH) test. The analysis included 44 patients with well-controlled AH, and 22 subjectively healthy volunteers aged 23 - 74 years, matched with the study group. During the study period, 22 patients in the study group were taking ACEI drugs, also in combination with other drug groups in terms of gender and age. 19 patients were taking other groups of drugs, including: ARB, beta-blockers, alpha-blockers, CCB, diuretics, also in combination, while 3 patients were not taking medication for AH; they were recommended non-pharmacological treatment. Blood biochemical tests, ambulatory blood pressure monitoring (ABPM) and PORH test using LDF were performed. The study showed that the PORH flow parameters were not differ statistically significantly between the study and control groups (p> 0.05). Statistically significant differences were shown in the PORH maximum level (ML) on the skin forearm between the study group not taking ACEI drugs and the control group. No statistically significant differences were shown between the study group taking ACEI and the control group. The pathogenesis of AH is multifactorial and depends, inter alia, on disturbances at the level of microcirculation. Proper treatment, especially with the use of ACEI, can improve the microcirculation in AH patients.

Abstract 13815: SARS-CoV-2 and Plasmodium Falciparum Co-Infection A Lethal Combination to the Heart

Introduction: COVID-19 pandemic has had an unprecedented impact worldwide, co-infections with neglected tropical diseases like Malaria can occur and affect the heart. Objective: Describe a unique case of Malaria and SARS CoV2 infection occurring concurrently with cardiac complications. Clinical Case: A 69-year-old male, retired canoeing athlete, with well-controlled arterial hypertension, presented odynophagia, cough, and dyspnea on slight exertion for 2 days. On examination, O2 saturation was 91%, blood pressure 100/60 mmHg, regular heart rate of 110 bpm, positive PCR for SARS-CoV-2, elevated D-Dimer, and chest X-ray with evidence of viral pneumonia. He received supplemental oxygen, steroids, and paracetamol. Two days later, he presented with choluria, afternoon episodes of high fever preceded by chills and myalgia, and a thick blood smear showed Plasmodium falciparum (PF) trophozoites. Antimalarial treatment was started with primaquine 15mg, 20 mg of artemether, and 120 mg of Lumefantrine daily with the disappearance of fever until day 14 of onset of symptoms when he presented with acute heart failure (AHF) with a reduced ejection fraction of 45%. NYHA Class IV, arterial hypotension, sudden onset palpitations, and afternoon febrile episode. The electrocardiogram showed atrial fibrillation (AF) with a rapid irregular ventricular response of 120 bpm; The echocardiogram revealed a 7mm circumferential pericardial effusion, right ventricular dysfunction. Treatment with colchicine, enoxaparin, spironolactone, and bisoprolol was started. A new thick smear demonstrated the persistence of PF. A new antimalarial regimen was restarted, with the disappearance of the fever 48 hours after its onset, with the reversion of AF to sinus rhythm. Discussion: A unique case of concurrent COVID-19 and Malaria, which cause challenges to the heart and lead to cardiovascular complications. Conclusion: An exceptional case is presented, the coexistence of SARS-CoV-2 and PF infection-associated complications of myocarditis, pericarditis, new-onset AF, and AHF. This interaction should not go unnoticed, physicians’ awareness is key, and early diagnosis and treatment can be lifesaving, mitigate and offer the best chance of cure.

New-onset lichen planus and lichen planus flare in elderly women after COVID-19 vaccination.

Dear Editor, Owing to the widespread use of COVID-19 vaccines, the number of cutaneous vaccine-related adverse events has recently increased.1 We present two cases of lichen planus in elderly women following COVID-19 mRNA vaccination. The first patient presented with new-onset LP, whereas the second patient experienced an extensive LP flare after a 10-year remission. The first patient was an 82-year-old woman who developed an extensive pruritic rash 14 days after receiving a second dose of the Pfizer-BioNTech COVID-19 vaccine. Other possible triggers such as recent infections, medication changes, or stressful events preceding the eruption were ruled out. The patient had no significant medical history, other than well-controlled arterial hypertension. On physical examination, she had polygonal, purpuric, scaly papules in the axillary region, flexural wrists and forearms, ankles, buttocks, lower back, and abdomen (Figure 1). Mucosal lesions were not observed. Dermoscopy revealed mild desquamation and Wickham's striae. Skin biopsy demonstrated irregular epidermal hyperplasia with hypergranulosis and hyperkeratosis, vacuolar degeneration of the basal layer, and dense lymphocytic infiltrate in the superficial dermis (Figure 1). Considering the clinical presentation, histopathological analysis, and absence of an alternative trigger, we diagnosed LP triggered by the mRNA COVID-19 vaccine. Thus, we began treatment with prednisolone 20 mg daily, tapering the dose over 6 weeks, which resulted in gradual improvement of skin lesions. The second patient was a 68-year-old woman with a 2-week history of an intensely pruritic eruption that occurred 14 days after receiving a second dose of the Moderna COVID-19 (mRNA-1273) vaccine. Her medical history included arterial hypertension, hyperlipidemia, obesity, HLA-B27 spondyloarthritis, and LP, which was histologically confirmed 10 years ago and successfully treated with systemic and topical corticosteroids. During the examination, erythematous to violaceous squamous papules were discovered on the trunk, buttocks, and extremities, as well as around the ankles, flexural wrists, forearms, and axillary folds, with palmar involvement as well (Figure 2). Mucosal or nail lesions were absent. Dermoscopy revealed slight scaling and Wickham's striae, and a skin biopsy confirmed lichen planus. Therefore, we introduced 30 mg prednisolone, and tapered the dose to discontinuation over 6 weeks, which lead to the resolution of skin lesions. LP is a chronic inflammatory T-cell-mediated skin disease caused by various infections, drugs, and, in rare cases, vaccines.1-6 The most common vaccines causing LP are hepatitis B and influenza vaccines. Recently, the new-onset or reactivation of LP has been associated with COVID-19 infection and vaccination. Although most reported cases of LP following COVID vaccination were localized, we observed two cases of widespread LP.2-5 The majority of vaccine-related reactions occur in middle-aged women, implying an increased risk of such reactions in women, even in elderly ones, as observed in our cases.1, 6 Both our patients developed LP 14 days after receiving the second dose of mRNA COVID-19 vaccine, which is consistent with vaccine-related LP time onset.6 The immunopathogenesis of vaccine-induced LP likely involves Th1 cell activation with upregulation of proinflammatory cytokines IL-2, TNF-alpha, and IFN-y, which leads to apoptosis of basal keratinocytes, a hallmark of LP. However, the precise mechanism underlying LP (re)activation following vaccination remains unknown. Similarly, immune dysregulation after COVID-19 vaccination may result in the (re)activation of other immune-mediated skin diseases such as psoriasis, vitiligo, acne vulgaris, pemphigus vulgaris, and certain connective tissue diseases.2, 5 Likewise, COVID-19 pandemic has underlined the importance of dermatologists and rheumatologists in providing guidance regarding immunosuppressive and biological therapy considering their extensive experience with such treatments, as well as recognizing the immune-mediated aspects of COVID-19 infection and vaccination.7 Furthermore, as a result of a better understanding of COVID-19 disease mechanisms, novel therapeutic strategies utilizing adipose-derived mesenchymal stem cells (AD-MSCs) are being developed, and given their immuno-modulatory properties, could be employed to combat the disease.8 Finally, dermatologists should be aware of new-onset or flare-ups of LP in older women caused by COVID-19 vaccination as well as the possible (re)activation of other immune-mediated skin diseases.

Basic laboratory tests in patients with hypertension

The aim of the study was to assess the reactivity basic laboratory tests in patients with well-controlled arterial hypertension (AH). The analysis included 44 patients with well-controlled AH aged 23 to 74 years. Statistical analysis showed a significant effect of disease duration on the level of eGFR and NT-proBNP. The longer the disease duration, the lower the eGFR and the higher the NT-proBNP.

Association of myocardial work indices with controlled arterial hypertension, age, weight and conventional echocardiographic parameters in women

Abstract Funding Acknowledgements Type of funding sources: None. Objective By incorporating myocardial deformation and afterload, novel echocardiographic myocardial work indices appear to be advantageous over the load-dependent left ventricular (LV) strain. As such, these indices might provide a better and load-independent estimation of LV function in patients with chronically increased afterload. To date, however, little is known about the relation of these indices to clinical and conventional echocardiographic parameters. Purpose Our aim was to evaluate the relationship between myocardial work indices and age, weight, conventional echocardiographic parameters, and the presence of previously defined well-controlled arterial hypertension (AH) in women without cardiovascular diseases. Methods We retrospectively analyzed echocardiographic data of women, included to the BEFRI (BErlin Female RIsk evaluation) trial. Global Work Index (GWI), Global Constructive Work (GCW), Global Wasted Work (GWW) and Global Work Efficiency (GWE) were calculated using commercially available software based on noninvasive pressure-strain loops. Mulitvariate analysis of covariance was applied to investigate the relation of myocardial work indices with the above mentioned variables. Results A total of 224 women were included in the final analysis. 155 of them were normotensive and 69 had controlled AH. Women with AH were significantly older (67 ± 12 y. vs. 54 ± 13 y, p < 0.05), had higher blood pressure (136 ± 10/77 ± 6 mmHg vs. 121 ± 7/70 ± 6 mmHg, p < 0.05), higher body mass index (28 ± 5 kg/m² vs. 24 ± 4 kg/m², p < 0.05), thicker LV walls (septum: 12 ± 2 mm vs. 9 ± 1 mm; posterior wall: 11 ± 1 mm vs. 9 ± 1 mm, p < 0.05 for both), higher left atrial volume index (35 ± 8 ml/m² vs. 29 ± 5 ml/m², p < 0.05) and longer IVRT (103 ± 27 ms vs. 85 ± 24 ms, p < 0.05). LV ejection fraction, LV internal dimensions and TAPSE were within a normal range and did not differ between groups. Patients with AH showed lower global longitudinal strain (GLS) (19 ± 3% vs. 20 ± 2%, p < 0.05), higher GWI and GCW (2214 ± 285 mmHg% vs. 2045 ± 244 mmHg%, 2445 ± 316 mmHg% vs. 2256 ± 272 mmHg%; p < 0.05 for both) (Fig. 1), whereas GWW and GWE did not differ significantly (112 ± 59 mmHg% vs 101 ± 51 mmHg% and 95 ± 3% vs. 95 ± 2%). In the multivariate analysis GWI and GCW, but not GWW or GWE, were significantly positively associated with the presence of AH (s. Table). Besides that, GWI and GCW were positively related to LVEF and LVEDD. GWW showed negative relation to LVEF and a positive relation with IVRT. GWE was positively related to LVEF, and negatively to IVRT. None of the indices was significantly related to age. Conclusion We have defined the relationship of various myocardial work indices with weight, conventional echocardiographic parameters, and the presence of AH. The higher GWI and GCW in patients with AH might suggest higher energetic expenditure of myocardium due to increased afterload. The prognostic impact of these findings remains to be defined.

The “Comorbid Patient” Scale as a General practitioner’s tool to increase treatment adherence in patients living in rural areas

Aim . To develop a visual aid “Comorbid patient Scale” and evaluate its effectiveness through dynamic follow-up of patients with chronic non-communicable diseases (NCDs) in outpatient practice. Materials and methods. The prevalence of risk factors and NCDs were analyzed in the course of a retrospective study of 1444 patients in rural areas. A visual aid “Comorbid Patient Scale” developed on obtained data has been evaluated in a 3-month prospective comparative study of 93 patients with NCDs, randomized to group 1, in which the Scale was used ( n = 47), and a control group (group 2, n = 46). Results. Group 1 showed a statistically significant increase in adherence to treatment after using the Scale for 3 months: 81% vs 57% at baseline ( p < 0.05); in group 2 similar indicators were: 61% vs 54% (the difference is not significant). In group 1, the proportion of smoking patients (39% vs 15% ( p < 0.05)) and the number of patients with hypercholesterolemia (23% vs 0% ( p < 0.05)) significantly decreased; the number of patients with well-controlled arterial hypertension increased from 47% to 87% ( p < 0.05). A similar dynamics was observed in group 2, however, the difference was not statistically significant. At baseline and 3 months later, the share of patients without exacerbation of diseases of the musculoskeletal system and respiratory tract diseases was the same across the groups. Conclusion. The use of “Comorbid patient Scale” compared to standard patient management increases patient adherence to treatment by 17%, reduces the share of smoking patients by 21%, with hypercholesterolemia by 14%, with the achievement of target blood pressure indicators by 26%.

Correlations between Left Ventricular and Left Atrial Function Assessed by Speckle Tracking Echocardiography in Patients with Treated Well-Controlled Arterial Hypertension

Introduction. Even in patients with well-controlled arterial hypertension (AH) and without significant comorbidities, left ventricular (LV) and left atrial (LA) strain abnormalities may sometimes be found in speckle-tracking echocardiography. Therefore, the aim of this study was to investigate the correlation between LA strain and LV diastolic and systolic function in a group of patients with treated, well-controlled AH. Material and methods. LA contractile, conduit, and reservoir function, together with echocardiographic signs of LV diastolic function and LV global longitudinal strain (LV GLS), were assessed in 101 patients with treated, well-controlled AH who met the standard criteria of normal LV ejection fraction (LVEF) and normal LV diastolic function. Results. A relevant percentage of study participants presented lower than reference LV (−18.7% for LV GLS) and LA strain (32.9% for LAS during reservoir phase, LASr; −15.9% for LAS during contraction phase, LASct; and −13.9% for LAS during conduit phase, LAScd) values. Moreover, there were statistically significant differences in LA longitudinal strain (LAS) values (LASr (31.43 vs. 36.33; p = 0.0007) and LAS LAScd (−13.09 vs. −15.79; p = 0.008)) between patients with high (>the absolute value of −20%) and lower (≤the absolute value of −20%) LV GLS, confirmed by significant correlations between LASr, LAScd, and GLS. In the correlations analysis between LAS values and LV diastolic function parameters, statistical significance was obtained for the following: LASct (contraction) versus e’avg, LASct versus E/A, LASct versus A, LAScd versus e’avg, LAScd versus E/A, and LAScd versus A. Conclusions. LV and LA strain abnormalities occurred within a significant percentage of patients with treated, well-controlled AH. Impaired LA strain is associated with lower LV strain and reduced LV diastolic function parameters, reflecting both the passive and active properties of the LA.

Re-initiation of anticoagulation after central nervous system hemorrhage during treatment with direct oral anticoagulants: a single hospital cohort study.

Central nervous system (CNS) hemorrhage is a serious complication related to direct oral anticoagulant (DOAC) therapy. Current recommendations about re-initiation of anticoagulation treatment are limited to expert opinions. For this purpose, we analyzed the data of all consecutive DOAC patients with CNS hemorrhage, in whom DOACs were reinitiated. Over a 6-year period (2012-2018), all consecutive patients with CNS hemorrhage (subdural, subarachnoid, intracerebral, spinal), while receiving DOACs, were included in this observational single-center cohort study. DOAC therapy was reinitiated only in patients with well-controlled arterial hypertension and diabetes, as well as exclusion of vascular malformations and cerebral amyloid angiopathy. The composite primary endpoint comprised of recurrent CNS hemorrhage, ischemic stroke, and mortality; secondary endpoints were separate aforementioned outcomes. Of the 54 patients included, 18 died within a month of CNS hemorrhage. The average observational time was 590days. DOACs were reinitiated in 13/36 patients (36%); of these patients, three died: none due to ischemic stroke or recurrent CNS bleeding. In 23 patients, anticoagulation was not reinitiated; of these patients, 10 died: three from recurrent CNS hemorrhage, one due to ischemic stroke, and six from causes unrelated to stroke. In carefully selected patients, re-initiation of DOAC therapy did not increase the rate of both endpoints. Recommendations for DOAC re-initiation, which include hypertension and diabetes control, as well as treated vascular malformations, and excluded cerebral amyloid angiopathy, appear to be valid in clinical practice.

Increased arterial stiffness – similar findings in patients with inflammatory bowel disease without prior hypertension or diabetes and in patients with well-controlled hypertension

Purpose: Chronic inflammatory diseases are related with earlier onset of atherosclerosis. We hypothesized that inflammatory bowel disease patients with chronic, systemic inflammation have an increased arterial stiffness associated with the disease duration. Also, we wanted to compare arterial stiffness markers between inflammatory bowel disease and well-controlled hypertension patients.Materials and methods: A total of 89 inflammatory bowel disease patients (60 patients with Crohn’s disease and 29 patients with ulcerative colitis, age range 20–64 years) without history of arterial hypertension or diabetes were enrolled and age matched with a control group of patients (73 patients, age range 25–69 years, 41 (56.1%) males) with known history of well-controlled arterial hypertension. We have used a noninvasive device that simultaneously measures brachial blood pressure and estimates PWV and AIx in inflammatory bowel disease and hypertension groups of patients.Results: Patients with pathological PWV values were significantly older, had significantly longer duration of inflammatory bowel disease, higher values of serum cholesterol and HDL-cholesterol, and higher AIx (17.4% vs. 9.8%) (all p < .05). Higher PWV was associated with age and duration of inflammatory bowel disease in the linear regression model. PWV values were higher in hypertensive patients in the first two age quartiles while interestingly, in the last two quartiles, PWV was lower than in inflammatory bowel disease group of patients.Conclusions: Chronic subclinical inflammation is responsible for dyslipidemia and accelerated atherosclerosis which consequently alterates arterial elasticity. Inflammatory bowel disease and its duration should also be considered a risk factor for subclinical organ damage, as well as hypertension.

Improvement of left ventricular diastolic function and left heart morphology in young women with morbid obesity six months after bariatric surgery.

Obesity contributes to left ventricular (LV) diastolic dysfunction (LVDD) and may lead to diastolic heart failure. Weight loss (WL) after bariatric surgery (BS) may influence LV morphology and function. Using echocardiography, this study assessed the effect of WL on LV diastolic function (LVDF) and LV and left atrium (LA) morphology 6 months after BS in young women with morbid obesity. Echocardiography was performed in 60 women with body mass index ≥ 40 kg/m², aged 37.1 ± ± 9.6 years prior to and 6 months after BS. In 38 patients, well-controlled arterial hypertension was present. Heart failure, coronary artery disease, atrial fibrillation and mitral stenosis were exclusion criteria. Parameters of LV and LA morphology were obtained. To evaluate LVDF, mitral peak early (E) and atrial (A) velocities, E-deceleration time (DcT), pulmonary vein S, D and A reversal velocities were measured. Peak early diastolic mitral annular velocities (E') and E/E' were assessed. Mean WL post BS was 35.7 kg (27%). A postoperative decrease in LV wall thickness, LV mass (mean 183.7 to 171.5 g, p = 0.001) and LA parameters (area, volume) were observed. LVDD was diagnosed in 3 patients prior to and in 2 of them subsequent to the procedure. An improvement in LVDF Doppler indices were noted: increased E/A, D and E' lateral, and decreased S/D and lateral E/E'. None of the patients showed increased LV filling pressure. No significant correlations between hypertension and echo-parameters were demonstrated. Six months after BS weight loss resulted in the improvement of LVDF and left heart morphology in morbidly obese women. (Cardiol J 2018; 25, 1: 97-105).

P235Relation between myocardial deformation by three-dimensional speckle tracking analysis , control of the hypertension and functional capacity in patients with systemic hypertension.

The purpose of this study was to investigate left ventricular (LV) function in hypertensive patients by 3-dimensional (3D) speckle tracking imaging, and determine the relation between the LV mechanics and functional capacity in this population. This cross-sectional study included 20 treated subjects with well-controlled arterial hypertension (group B) and 20 treated participants with uncontrolled hypertension (group A), adjusted by gender and age. All the subjects underwent 24-hour blood pressure monitoring, complete 2-dimensional and 3D examination, and exercise testing. Patients had similar 3D LV ejection fraction. LV mass was higher in group of uncontrolled hypertension (154.71 ± 49.7 g/m2 versus 147.12±44.8 g/m2 p < 0.01), as well as E/E'ratio (11.4 versus 8.9, p =0.02). 3D global longitudinal and circumferential strain and strain rate were significantly decreased in patients with inadequately controlled hypertension (LS 16.25% versus -19.24%, p=0.007, L-SR -0.97/sec versus -1.48/sec, p=0.04, CS -17.89%versus -21.76%, p=0.04, respectively), while the difference of radial strain and strain rate did not reach statistical significance. Group A of patients had also a significantly lower functional capacity (mean duration of test 13,3 min. versus 17,4 min, nr. of METS 9.4 versus 13.7). Duration of exercise was independently associated with LV mass , mean BP at daytime , E/E' ratio and 3D global longitudinal strain (β = 0.34, p = 0.02) in the whole hypertensive population in our study. In conclusion, LV longitudinal strain and functional capacity are significantly impaired in the patients with uncontrolled hypertension in comparison with the well-controlled hypertensive patients and are independently associated.

Two- and Three-Dimensional Speckle Tracking Analysis of the Relation Between Myocardial Deformation and Functional Capacity in Patients With Systemic Hypertension

The purpose of this study was to investigate left ventricular (LV) mechanics in hypertensive patients by 2- and 3-dimensional (3D) speckle tracking imaging, and determine the relation between the LV mechanics and functional capacity in this population. This cross-sectional study included 51 recently diagnosed, untreated, hypertensive patients, 49 treated subjects with well-controlled arterial hypertension, 52 treated participants with uncontrolled hypertension, and 50 controls adjusted by gender and age. All the subjects underwent 24-hour blood pressure monitoring, complete 2-dimensional and 3D examination, and cardiopulmonary exercise testing. 3D global longitudinal, circumferential, radial, and area strains were similar between the control group and well-controlled hypertensive patients but significantly decreased in comparison with patients with untreated or inadequately controlled hypertension. Similar findings were obtained for LV torsion and twist rate, whereas LV untwisting rate significantly deteriorated from the controls, across the well-controlled group, to the patients with untreated or uncontrolled hypertension. Peak oxygen uptake was significantly lower in the patients with untreated and uncontrolled hypertension than in the controls and the well-treated hypertensive patients. Peak oxygen uptake was independently associated with LV untwisting rate (β = 0.28, p = 0.03), 3D LV ejection fraction (β = 0.31, p = 0.024), and 3D global longitudinal strain (β = 0.26, p = 0.037) in the whole hypertensive population in our study. In conclusion, LV mechanics and functional capacity are significantly impaired in the patients with uncontrolled and untreated hypertension in comparison with the controls and the well-controlled hypertensive patients. Functional capacity is independently associated with 3D global longitudinal strain, LV untwisting rate, and 3D LV ejection fraction.

Esophageal Long-Term ECG Reveals Paroxysmal Atrial Fibrillation

A 79-year-old man was referred for coronary angiography because of atypical chest pain. The patient's medical history included a myocardial infarction 5 years previously and well-controlled arterial hypertension. Three months before this admission he reported atypical chest pain, sometimes associated with palpitations lasting seconds up to a few minutes. Hence, he underwent ambulant 24-hour ECG, which revealed frequent atrial premature beats but no other arrhythmia. On admission, the patient was in sinus rhythm. Echocardiography showed normal ventricular function without structural heart disease. After successful percutaneous transluminal coronary angioplasty, the patient was included in a study …

The dilemma of immediate preoperative hypertension: to treat and operate, or to postpone surgery?

Study objective To evaluate the efficacy and complications of immediate preoperative reduction of arterial blood pressure (BP) in patients with well-controlled hypertension but with diastolic blood pressure (DBP) between 110 and 130 mmHg on arrival at the operating room (OR). Design Prospective, randomized, large-sample study. Setting University-affiliated, 550-bed community hospital. Patients 989 patients with well-controlled hypertension, who were scheduled for surgery, and who had no previous myocardial infarction, unstable or severe angina pectoris, renal failure, pregnancy induced hypertension, left ventricular hypertrophy, previous coronary revascularization, aortic stenosis, preoperative dysrhythmias, conduction defects, or stroke. Interventions Patients with DBP between 110 and 130 mmHg were randomly allocated to two groups: 400 patients in the control group and 589 patients serving as the study group. The control group had their surgery postponed and they remained in hospital for BP control, and the study patients received 10 mg of nifedipine intranasally delivered. The patients were observed for cardiovascular and neurological complications during the intraoperative period and over the first three postoperative days. Measurements and main results The two groups were similar in age, gender, type of surgery, duration of anesthesia, and intraoperative fluid administration. There were no statistically significant differences in postoperative complications.The hospitalization time was considerable shorter in the study group than in the control group. Conclusions Immediate preoperative reduction of DBP with intranasal nifedipine is safe in patients with well-controlled arterial hypertension but they presented with severe to very severe hypertension for patients in the OR. We were able to avoid unnecessary surgery postponement and attendant costs.
