F.; MACEDO, T. A.; LEBKUCHEN, A.; CARDOZO, K. H. M.; MARTINS, F. C.; AZAM, I. F. B.; COSTA-HONG, V.; BAPTISTA, M. L.; ROCHITTE, C. E.; BORTOLOTTO, L. A.; LORENZI-FILHO, G.; DRAGER, L. F.- Intermittent claudication and severe renal artery stenosis are independently associated in hypertensive patients referred for renal arteriography(2017) MACEDO, Thiago Andrade; DRAGER, Luciano Ferreira; PEDROSA, Rodrigo Pinto; MUELA, Henrique Cotchi Simbo; COSTA-HONG, Valeria; KAJITA, Luiz Junia; BORTOLOTTO, Luiz AparecidoOBJECTIVE: The purpose of this study was to evaluate the association between the presence of clinical symptoms of peripheral artery disease and severe renal artery stenosis in patients referred for renal angiography. METHOD: We included 82 patients with clinical suspicion of renovascular hypertension and performed an imaging investigation (renal Doppler ultrasound and/or renal scintigraphy) for possible renal artery stenosis. All patients underwent renal arteriography and were examined for peripheral artery disease based on the presence of intermittent claudication and ankle-brachial index test results. Severe renal artery stenosis was defined as a lesion causing 70% obstruction. RESULTS: Severe renal artery stenosis was present in 32 of 82 (39%) patients. Patients with severe renal artery stenosis were older (63 +/- 12 vs 56 +/- 12 years, p=0.006), had more intermittent claudication (55 vs 45%, p=0.027), and had a greater prevalence of an ankle-brachial index <0.9 (44% vs 20%, p=0.021) than patients without severe renal artery stenosis. Multivariate logistic regression analysis showed that the presence of intermittent claudication was independently associated with renal artery stenosis >= 70% (OR: 3.33; 95% CI 1.03-10.82, p=0.04), unlike the ankle-brachial index, which showed no association (OR: 1.44; 95% CI 0.37-5.66, p=0.60). CONCLUSION: Intermittent claudication is independently associated with severe renal artery stenosis (>= 70%) in patients clinically suspected of having renovascular hypertension.
- The impact of metabolic syndrome on metabolic, proinflammatory and prothrombotic markers according to the presence of high blood pressure criterion(2013) GIL, Juliana S.; DRAGER, Luciano F.; GUERRA-RICCIO, Grazia M.; MOSTARDA, Cristiano; IRIGOYEN, Maria C.; COSTA-HONG, Valeria; BORTOLOTTO, Luiz A.; EGAN, Brent M.; LOPES, Heno F.OBJECTIVES: We explored whether high blood pressure is associated with metabolic, inflammatory and prothrombotic dysregulation in patients with metabolic syndrome. METHODS: We evaluated 135 consecutive overweight/obese patients. From this group, we selected 75 patients who were not under the regular use of medications for metabolic syndrome as defined by the current Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults criteria. The patients were divided into metabolic syndrome with and without high blood pressure criteria (>= 130/>= 85 mmHg). RESULTS: Compared to the 45 metabolic syndrome patients without high blood pressure, the 30 patients with metabolic syndrome and high blood pressure had significantly higher glucose, insulin, homeostasis model assessment insulin resistance index, total cholesterol, low-density lipoprotein-cholesterol, triglycerides, uric acid and creatinine values; in contrast, these patients had significantly lower high-density lipoprotein-cholesterol values. Metabolic syndrome patients with high blood pressure also had significantly higher levels of retinol-binding protein 4, plasminogen activator inhibitor 1, interleukin 6 and monocyte chemoattractant protein 1 and lower levels of adiponectin. Moreover, patients with metabolic syndrome and high blood pressure had increased surrogate markers of sympathetic activity and decreased baroreflex sensitivity. Logistic regression analysis showed that high-density lipoprotein, retinol-binding protein 4 and plasminogen activator inhibitor-1 levels were independently associated with metabolic syndrome patients with high blood pressure. There is a strong trend for an independent association between metabolic syndrome patients with high blood pressure and glucose levels. CONCLUSIONS: High blood pressure, which may be related to the autonomic dysfunction, is associated with metabolic, inflammatory and prothrombotic dysregulation in patients with metabolic syndrome.
- Does Obstructive Sleep Apnea Influence Blood Pressure and Arterial Stiffness in Response to Antihypertensive Treatment?(2018) FATURETO-BORGES, Fernanda; JENNER, Raimundo; COSTA-HONG, Valeria; LOPES, Heno F.; TEIXEIRA, Sandra H.; MARUM, Elias; GIORGI, Dante A. M.; CONSOLIM-COLOMBO, Fernanda M.; BORTOLOTTO, Luiz A.; LORENZI-FILHO, Geraldo; KRIEGER, Eduardo M.; DRAGER, Luciano F.Untreated obstructive sleep apnea (OSA) is common in patients with hypertension and may impair blood pressure (BP) and target-organ damage responses to antihypertensive therapy. In this study, we recruited hypertensive patients who underwent treatment with a 30-day regimen of hydrochlorothiazide 25 mg plus enalapril (20 mg BID) or losartan (50 mg BID) and were assessed with a baseline clinical evaluation, polysomnography, 24-hour ambulatory BP monitoring, and carotid-femoral pulse wave velocity. All the examinations except for polysomnography were repeated at 6 and 18 months of follow-up. We studied 94 hypertensive patients (mean age, 55 +/- 9 years). The frequency of OSA was 55%. Compared with baseline, we did not observe significant differences between groups in 24-hour BP, daytime systolic and diastolic BPs, or night-time systolic BP at 6 and 18 months. The BP control rate at 24 hours (<130/80 mmHg) was similar between the groups (baseline, 42.3% versus 45.2%; 6 months, 46.9% versus 57.5%; 18 months, 66.7% versus 61.5%). However, patients with OSA had higher night-time diastolic BP decrease than did the non-OSA group (6 months, -4.9 +/- 11.8 versus -0.3 +/- 10.3 mmHg; 18 months, -6.7 +/- 11.1 versus -1.2 +/- 10.6 mmHg; P=0.027). There were no differences in the number and class of antihypertensive medications prescribed during follow-up. In terms of arterial stiffness, patients with OSA had higher pulse wave velocity than did patients without OSA at baseline (10.3 +/- 1.9 versus 9.2 +/- 1.7 m/s; P=0.024), but both groups had similar decreases in pulse wave velocity during follow-up. In conclusion, with combined antihypertensive treatment aimed at controlling BP, hypertensive patients with OSA had similar 24-hour BP and arterial stiffness to those without OSA.
- Effects of CPAP on Metabolic Syndrome in Patients With OSA A Randomized Trial(2022) GIAMPA, Sara Q. C.; FURLAN, Sofia F.; FREITAS, Lunara S.; MACEDO, Thiago A.; LEBKUCHEN, Adriana; CARDOZO, Karina H. M.; CARVALHO, Valdemir M.; MARTINS, Franco C.; AZAM, Indira F. B.; COSTA-HONG, Valeria; LOPES, Heno F.; BAPTISTA, Mariana L.; ROCHITTE, Carlos E.; BORTOLOTTO, Luiz A.; LORENZI-FILHO, Geraldo; DRAGER, Luciano F.BACKGROUND: OSA is associated with metabolic syndrome (MS), but it is unclear whether OSA treatment with CPAP can revert MS. RESEARCH QUESTION: Does OSA treatment with CPAP per se have effects on the MS reversibility and the associated metabolic, adiposity and vascular parameters? STUDY DESIGN AND METHODS: The TREATOSA-MS trial is a randomized placebo-controlled trial that enrolled adult patients with a recent diagnosis of MS and moderate or severe OSA (apnea-hypopnea index [AHI], >= 15 events/h) to undergo therapeutic CPAP or nasal dilator strips (placebo group) for 6 months. Before and after each intervention, we measured anthropometric variables, BP, glucose, and lipid profile. To control potential-related mechanisms and consequences, we also measured adiposity biomarkers (leptin and adiponectin), body composition, food intake, physical activity, subcutaneous and abdominal fat (visceral and hepatic fat), and endothelial function. RESULTS: One hundred patients (79% men; mean age, 48 +/- 9 years; BMI, 33 +/- 4 kg/m(2); AHI, 58 +/- 29 events/h) completed the study (n = 50 per group). The mean CPAP adherence was 5.5 +/- 1.5 h/night. After 6 months, most patients with OSA randomized to CPAP retained the MS diagnosis, but the rate of MS reversibility was higher than observed in the placebo group (18% vs 4%; OR, 5.27; 95% CI, 1.27-35.86; P = .04). In the secondary analysis, CPAP did not promote significant reductions in the individual components of MS, weight, hepatic steatosis, lipid profile, adiponectin, and leptin, but did promote a very modest reduction in visceral fat and improved endothelial function (all analyses were adjusted for baseline values). INTERPRETATION: Despite the higher rate of MS reversibility after CPAP therapy as compared with placebo, most patients retained this diagnosis. The lack of significant or relevant effects on adiposity biomarkers and depots supports the modest role of OSA in modulating MS.
- Severe obstructive sleep apnea is associated with circulating microRNAs related to heart failure, myocardial ischemia, and cancer proliferation(2020) FREITAS, Lunara S.; SILVEIRA, Andre C.; MARTINS, Franco C.; COSTA-HONG, Valeria; LEBKUCHEN, Adriana; CARDOZO, Karina H. M.; BERNARDES, Fernanda M.; BORTOLOTTO, Luiz A.; LORENZI-FILHO, Geraldo; OLIVEIRA, Edilamar M.; DRAGER, Luciano F.Purpose Obstructive sleep apnea (OSA) is associated with multiple comorbid conditions including cardiovascular diseases and cancer. There is a growing interest in exploring biomarkers to understand the related mechanisms and improve the risk stratification of OSA. Circulating microRNAs (miRNAs) are single noncoding strands of nearly 22 nucleotides that posttranscriptionally regulate target gene expression. Our aim was to identify miRNA profiles associated with OSA. Methods We studied 48 male subjects, mostly Caucasian (63%) and overweight, divided by polysomnography into the no OSA control group (n = 6), mild OSA group (n = 12), moderate OSA group (n = 15), and severe OSA group (n = 15). The study groups were matched for age, body mass index (BMI), and body fat composition. miRNA profiles were measured from peripheral whole blood using two steps: (1) microarray analysis comprising more than 2500 miRNAs in a subsample of 12 subjects (three from each group); and (2) validation phase using real-time quantitative polymerase chain reaction (RTqPCR). Results The microarray assessment identified 21 differentially expressed miRNAs among the groups. The RT-qPCR assessment showed that miR-1254 and miR-320e presented a gradual increase in expression parallel to OSA severity. Linear regression analysis showed that severe OSA was independently associated with miR-1254 (ss = 68.4; EP = 29.8; p = 0.02) and miR-320e (ss = 76.1; EP = 31.3; p = 0.02). Conclusion Severe OSA is independently associated with miRNAs that are involved in heart failure (miR-1254), myocardial ischemia/reperfusion (miR-320e), and cell proliferation in some cancer types (miR-1254 and miR-320e). Future investigations addressing whether these miRs may provide prognostic information in OSA are needed.
- Obstructive sleep apnea is associated with interdialytic weight gain and increased long-term cardiovascular events in hemodialysis patients(2018) HARMON, Rebeca R.; LIMA, Jose Jayme G. De; DRAGER, Luciano F.; PORTILHO, Natanael P.; COSTA-HONG, Valeria; BORTOLOTTO, Luiz A.; LORENZI-FILHO, Geraldo; CANZIANI, Maria Eugenia F.BackgroundObstructive sleep apnea (OSA) is common in hemodialysis (HD) patients. The reasons for the high prevalence and whether OSA is associated with vascular impairment, end-organ damage, and prognosis are not completely clear.MethodsWe evaluated patients with low cardiovascular risk on HD, not treated by CPAP. Laboratory tests, sleep questionnaires (Berlin and Epworth) and polysonography studies, echocardiography, and markers of arterial stiffness and atherosclerosis were performed. After the initial evaluation, patients were followed up until cardiovascular events, renal transplantation, or death.ResultsFifty-five patients (49% male, 509years, body mass index 24.7 +/- 4.5kg/m(2)) were included. OSA (apnea-hypopnea index 5 events/h) occurred in 73% of the patients. The proportion of patients with interdialytic weight gain >2kg was higher in patients with OSA than those without OSA (96 vs. 55%; p=0.002). Left ventricular (LV) posterior wall thickness (10.0 +/- 1.9 vs. 11.3 +/- 1.8mm; p=0.04) and LV diastolic diameter (48 +/- 5 vs. 53 +/- 5mm; p=0.003) were higher in patients with OSA than in patients without OSA, respectively. Sleep questionnaires did not predict OSA. No significant differences were found in pulse wave velocity, carotid intima-media thickness, and ankle-brachial index between the groups. Multivariate analysis showed that interdialytic weight gain >2kg and LV diastolic diameter were independently associated with OSA. On follow-up (median 45months), OSA was found to be associated with a higher incidence of cardiovascular (CV) events (28 vs. 7%, log-rank=0.042).ConclusionsOSA was associated with increased risk of CV events. Significant (>2kg) interdialytic weight gain was independently associated with OSA.
- Determinantes das Propriedades Funcionais e Estruturais de Grandes Artérias em Indivíduos Saudáveis(2014) TOLEZANI, Elaine Cristina; COSTA-HONG, Valeria; CORREIA, Gustavo; MANSUR, Alfredo Jose; DRAGER, Luciano Ferreira; BORTOLOTTO, Luiz AparecidoBackground: Changes in the properties of large arteries correlate with higher cardiovascular risk. Recent guidelines have included the assessment of those properties to detect subclinical disease. Establishing reference values for the assessment methods as well as determinants of the arterial parameters and their correlations in healthy individuals is important to stratify patients. Objective: To assess, in healthy adults, the distribution of the values of pulse wave velocity, diameter, intima-media thickness and relative distensibility of the carotid artery, in addition to assessing the demographic and clinical determinants of those parameters and their correlations. Methods: This study evaluated 210 individuals (54% women; mean age, 44 +/- 13 years) with no evidence of cardiovascular disease. The carotid-femoral pulse wave velocity was measured with a Complior (R) device. The functional and structural properties of the carotid artery were assessed by using radiofrequency ultrasound. Results: The means of the following parameters were: pulse wave velocity, 8.7 +/- 1.5 m/s; diameter, 6,707.9 +/- 861.6 mu m; intima-media thickness, 601 +/- 131 mu m; relative distensibility, 5.3 +/- 2.1%. No significant difference related to sex or ethnicity was observed. On multiple linear logistic regression, the factors independently related to the vascular parameters were: pulse wave velocity, to age (p < 0.01) and triglycerides (p = 0.02); intima-media thickness, to age (p < 0.01); diameter, to creatinine (p = 0.03) and age (p = 0.02); relative distensibility, to age (p < 0.01) and systolic and diastolic blood pressures (p = 0.02 and p = 0.01, respectively). Pulse wave velocity showed a positive correlation with intima-media thickness (p < 0.01) and with relative distensibility (p < 0.01), while diameter showed a positive correlation with distensibility (p = 0.03). Conclusion: In healthy individuals, age was the major factor related to aortic stiffness, while age and diastolic blood pressure related to the carotid functional measure. The carotid artery structure was directly related to aortic stiffness, which was inversely related to the carotid artery functional property.
