Tan L, Liu Y, Liu J, Zhang G, Liu Z, Shi R. Association between insulin resistance and uncontrolled hypertension and arterial stiffness among US adults: a population-based study. Cardiovasc Diabetol 2023; 22:311. [PMID: 37946205 PMCID: PMC10637002 DOI: 10.1186/s12933-023-02038-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 10/18/2023] [Indexed: 11/12/2023] Open
Abstract
BACKGROUND Prior research has established the correlation between insulin resistance (IR) and hypertension. While the association between triglyceride-glucose (TyG) index, a reliable surrogate marker of IR, and uncontrolled hypertension as well as arterial stiffness among individuals with hypertension remains undisclosed. METHODS In this study, a total of 8513 adults diagnosed with hypertension from the National Health and Nutrition Examination Survey 1999-2018 were included. The primary outcome of the study are arterial stiffness (represented with estimated pulse wave velocity, ePWV) and uncontrolled hypertension. Logistic regression model, subgroup analysis, restricted cubic spine, and smooth curve fitting curve were conducted to evaluate the association between the IR indicators and uncontrolled hypertension and arterial stiffness in individuals with hypertension. RESULTS Among included participants, the overall prevalence of uncontrolled hypertension was 54.3%. After adjusting for all potential covariates, compared with the first quartile of TyG index, the risk of uncontrolled hypertension increased about 28% and 49% for participants in the third quartile (OR, 1.28; 95% CI 1.06-1.52) and the fourth quartile (OR, 1.49; 95% CI 1.21-1.89) of TyG index, respectively. The higher OR of TyG index was observed in participants taking antihypertensive medication [fourth quartile versus first quartile (OR, 2.03; 95% CI 1.37-3.11)]. Meanwhile, we explored the potential association between TyG index and arterial stiffness and found that TyG index was significantly associated with increased arterial stiffness (β for ePWV, 0.04; 95% CI 0.00-0.08; P = 0.039). However, traditional IR indicator HOMA-IR showed no significant positive correlation to uncontrolled hypertension as well as arterial stiffness in US adults with hypertension. CONCLUSION Elevated levels of the TyG index were positive associated with prevalence of uncontrolled hypertension and arterial stiffness among US adults with hypertension.

Association between glycated hemoglobin and functional outcomes in patients with intracranial large artery atherosclerotic disease-related acute ischemic stroke: identifying the magic number. Front Neurol 2023; 14:1249535.

Abstract
Objective This study aimed to investigate the effect of the glycated hemoglobin A1c (HbA1c) level on the functional outcome (FOC) in patients with intracranial large artery atherosclerotic disease (ICLAD)-related acute ischemic stroke (AIS). Methods This retrospective study enrolled patients with ICLAD-related AIS who were admitted to King Fahd University Hospital between January 2017 and September 2021. Patients were divided into two groups based on the optimal cutoff HbA1c level determined using receiver operating characteristic curve analysis-those with HbA1c ≤6.9% and those with HbA1c >6.9%. Demographic and other clinical characteristics were compared between the two groups using chi-square tests. The association between HbA1c and 90-day FOC was assessed using the chi-square test and odds ratios (ORs). Multivariate analysis was performed to adjust for confounding factors. Results A total of 140 patients were included in the analysis. A significant association was observed between the HbA1c level and FOC. Compared to patients with HbA1c ≤6.9%, patients with HbA1c >6.9% were more likely to have an unfavorable FOC [p = <0.001, OR = 2.05, 95% confidence interval (CI) = 1.33-3.14]. The association between HbA1c >6.9% and unfavorable FOC was sustained even after adjusting for confounding factors (p = 0.008) and atherosclerosis risk factors (p = 0.01). HbA1c >6.9% was also associated with higher ORs for in-hospital complications (p = 0.06, OR = 1.34, 95% CI = 1.02-1.77) and mortality (p = 0.07, OR = 1.42, 95% CI = 1.06-1.92) although these associations did not attain significant p-values. Conclusion HbA1c >6.9% was significantly associated with unfavorable FOC in ICLAD-related AIS. However, further studies with larger sample sizes are required to verify whether HbA1c is an independent predictor of poor FOC. Nevertheless, targeting HbA1c <7% should be the goal of physicians when managing patients at high risk of ICLAD.

[PMID: 37048548 PMCID: PMC10095290 DOI: 10.3390/jcm12072464] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 03/20/2023] [Accepted: 03/21/2023] [Indexed: 04/14/2023] Open
Abstract
The relationship between the morning blood pressure surge (MBPS) and cardiovascular risk is inconclusive. Previous studies have not taken into consideration dipping status in examining the MBPS and its associated factors. The aim was to examine factors associated with the MBPS in dippers and non-dippers. The MBPS was calculated by data obtained from ambulatory blood pressure monitoring, using the definition of sleep-trough morning surge. Dipping systolic blood pressure (DipSBP) was defined as [1 - (SBPsleeping/SBPawake)] × 100%. The value in milliseconds of standard deviation of normal-to-normal RR interval after waking up (SDNNaw) was calculated during the 2 h period after waking up. A total of 140 eligible subjects were divided into dippers (n = 62) and non-dippers (n = 78). Multiple regression analysis on data for all subjects revealed different correlations with the MBPS: positive in age, body mass index (BMI), and DipSBP, and inverse in cholesterol/high density lipoprotein-cholesterol (HDL-C) ratio, fasting blood glucose, and 2 h SDNNaw. When dippers were examined separately, age, female gender, and BMI correlated positively with MBPS, while cholesterol/HDL-C ratio and 2 h SDNNaw correlated negatively. For non-dippers, only age was associated with the MBPS. The factors associated with the MBPS were different for dippers and non-dippers. The MBPS seems to be a physiological response in this dipper group because age and BMI correlated positively with the MBPS, while parasympathetic neural activity after waking up and cholesterol/HDL-C ratio showed inverse correlations.

Abstract
Albuminuria is a prognostic marker of worsening renal outcomes in people with hypertension and type 2 diabetes. High home systolic blood pressure is associated with the development of diabetic nephropathy. We assessed the impact of chronic high home blood pressure on diabetic nephropathy progression 10 years after study entry. The participants measured their blood pressure three times in the morning for 14 days at study entry and 10 years after study entry. A retrospective cohort of 165 people with type 2 diabetes at a single hospital was classified into four groups (good control maintenance, improvement, deterioration, and continuous high blood pressure groups) according to a morning home systolic blood pressure ≥125 mmHg at study entry and 10 years after study entry. Logistic regression analysis was performed to determine the association between home blood pressure control and the progression of diabetic nephropathy. After 10 years of entry, the status of nephropathy improved for 5.5% of the participants, remained unchanged for 72.1%, and progressed for 22.4%. The odds ratio of the continuous high blood pressure group versus that of the good control maintenance group for the progression of diabetic nephropathy was 10.41 (95% CI, 1.26-86.15). After adjusting for the introduction of renin-angiotensin-aldosterone system inhibitors during the follow-up period, there was no significant difference in the odds ratio of worsening nephropathy between these groups. The deterioration and improvement groups did not have significant diabetic nephropathy progression compared to the good control maintenance group. Chronic high home blood pressure was associated with the progression of diabetic nephropathy, and RAAS inhibitors could attenuate the negative effect. We demonstrated that chronic home blood pressure was associated with the progression of diabetic nephropathy.

Abstract
Objective Admission hyperglycemia is an established risk factor for functional outcome in patients with acute ischemic stroke. However, the association between glycated hemoglobin (HbA1c) and prognosis in patients with acute anterior circulation ischemic stroke (AACIS) remains controversial. This study aimed to explore whether elevated HbA1c levels are associated with functional outcome in AACIS patients. Participants and Methods We enrolled patients with AACIS hospitalized in the First Hospital Affiliated to Soochow University from March 2018 to January 2021. Patients were categorized into three groups based on baseline HbA1c: HbA1c ≤ 6.5%, 6.5% < HbA1c ≤ 8.0%, and HbA1c > 8.0%. Ninety-day modified Rankin Scale scores of 0–1 and 0–2 were defined as excellent and favorable functional outcome, respectively. Early neurological improvement was regarded as a reduction in the National Institutes of Health Stroke Scale (NIHSS) score ≥ 4 points compared with that on admission, or an NIHSS score of 0–1 at discharge. The association between HbA1c and clinical outcome in acute ischemic patients was assessed by logistic regression and adjusted for confounding factors. Subgroup analyses by TOAST classification were also conducted. Results The study included 326 patients. The proportion with favorable outcome was significantly lower in the HbA1c > 8.0% group than the HbA1c ≤ 6.5% group (30.4 vs. 55.2%; p < 0.01). Binary logistic regression analysis demonstrated that increasing HbA1c levels (as a continuous variable) were associated with reduced functional independence (adjusted OR = 0.739; 95% CI: 0.605–0.904; p = 0.003). In subgroup analyses, higher HbA1c was also associated with favorable outcome in large-artery atherosclerosis (LAA)-type patients (adjusted OR = 0.776; 95% CI: 0.614–0.981; p = 0.034), but not in LAA group. Conclusions HbA1c level was an independent predictor of worse functional outcome in patients with AACIS, particularly in those with LAA. For patients with anterior circulation atherosclerosis, strict adherence to a target HbA1c < 6.5% may be required.

Abstract
BACKGROUND The study investigated predictors of poor glycemic control in type 2 diabetes (T2DM). METHODS Data on demographics, anthropometric and clinical parameters were collected in a cross-section survey from 140 adults with T2DM, using standard tools/instruments. Glycated hemoglobin (A1C) was assessed as a measure of glycemic control. RESULTS Majority (83.3%) had poor glycemic control status of which about 95% constitute the elderly. The elderly (OR= 5.90, 95% Cl: 1.66-20.96) were more likely associated with poor glycemic control than the non-elderly (p = 0.006). Adjustment for significant predictor variables: Age, waist-hip ratio (WHR), Fasting plasma glucose (FPG) and Systolic blood pressure (SBP), although attenuated the odds (OR= 5.00, 95% CI: 1.19-20.96) of poor glycemic control, it still remained significantly (p = 0.028) higher in the elderly. Patients outside tight FPG control significantly (p = 0.001) showed poor glycemic cotrol than those within tight FPG (OR= 17.39, 95%Cl: 5.83-51.90), even with attenuated OR (OR= 10.85, 95%Cl: 3.10-37.96) and (OR=12.08, 95%Cl: 3.64-40.09) when non-significant and significant predictor variables were accounted for, respectively. CONCLUSION Age, WHR, FPG, and SBP were significantly associated with differences in glycemic control. The elderly and FPG outside tight control showed significantly increased odds of poor glycemic control status.

Morning blood pressure surge is associated with autonomic neuropathy and peripheral vascular disease in patients with diabetes. J Hum Hypertens 2019; 34:495-504.

Abstract
Although vascular and autonomic nervous system have been involved in the regulation of morning surge in blood pressure (MBPS), data on clinical correlates of MBPS in diabetic population are scarce, in particular with regard to diabetic complications. This study was aimed at investigating predictors and correlates of MBPS in diabetes. In a cross-sectional study including 167 patients with diabetes (age 58.5 ± 11.1 years, duration 15.9 ± 12.1 years), clinical variables, diabetic and neuropathic complications, and MBPS (using 24-h ambulatory blood pressure monitoring) were measured. The upper quartile of MBPS (>30.5 mmHg) was associated with higher values of waist circumference (P = 0.027), triglycerides (P = 0.021), and Michigan Diabetic Neuropathy Score (P = 0.042), with lower HDL cholesterol (P = 0.030), and with the presence of cardiovascular autonomic neuropathy (CAN) (P = 0.016) and peripheral vascular disease (PVD) (P < 0.0001). In a logistic regression analysis, PVD (odds ratio: 10.2, P = 0.001), CAN (odds ratio: 6.09, P = 0.016), and diastolic blood pressure (BP) (odds ratio: 1.06, P = 0.022) predicted MBPS upper quartile (r2 = 0.20, P = 0.0005). In a multiple regression analysis, PVD (P = 0.002) and diastolic BP (P = 0.003) were the only determinants of MBPS (r2 = 0.20). MBPS upper quartile was associated with BP dipping (systolic BP day-night reduction > 10%) (P = 0.012), and MBPS was positively related to systolic (rho = 0.41, P < 0.0001) and diastolic BP day-night reduction. In conclusion, metabolic syndrome stigmata, diastolic BP, CAN and PVD are the main predictors of MBPS in the diabetic population. Excessive MBPS and nondipping are not concurrent 24-h BP alterations. Autonomic dysfunction might exert an exacerbating effect on MBPS phenomenon.

Abstract
PURPOSE OF REVIEW This review considers the relationship between abnormal blood pressure (BP) variability and autonomic dysfunction through an attempt to answer questions about its clinical relevance and pertinence to diabetes and cardiovascular autonomic neuropathy (CAN) and which therapeutic measures can lessen its cardiovascular impact. RECENT FINDINGS Office, ambulatory, and home BP monitoring identify posture-related, circadian, short-term, and long-term BP variabilities. Abnormal BP variability is a risk marker for organ damage, mortality, and cardiovascular events. Moreover, BP variability changes are common in diabetes and associated with CAN and possibly exacerbated by comorbidities like nephropathy, obstructive sleep apnoea syndrome, and chronic pain. The prognostic role of nondipping and reverse dipping is well documented in diabetes. Some findings suggest the possibility of restoring dipping with the dosage time of antihypertensive agents. Diabetes is a favorable scenario for altered BP variability, which might mediate the harmful effects of CAN. Preliminary data suggest the protective effect of targeting BP variability. However, further longitudinal outcome studies are needed. In the meantime, BP variability measures and practical expedients in antihypertensive treatment should be implemented in diabetes.

Abstract
AIMS/INTRODUCTION Poor sleep quality is associated with obesity and diabetes. The adipocyte-derived hormone, leptin, was recently shown to underlie the link between abnormal sleep and obesity. We aimed to investigate the association between leptin and sleep quality in type 2 diabetes patients. MATERIALS AND METHODS In the present cross-sectional study, we studied 182 type 2 diabetes patients, among whom 113 were diagnosed with obesity (body mass index ≥25 kg/m2 ). Fasting plasma leptin levels were measured, and sleep architecture was assessed using single-channel electroencephalography. RESULTS Using unadjusted analyses, the obese type 2 diabetes patients, but not their non-obese counterparts, showed a positive correlation between plasma leptin levels and a parameter for deep sleep assessed by delta power during the first sleep cycle. Multivariate analysis showed that plasma leptin levels were positively associated with delta power, but not with the total sleep time, after adjusting for potential confounders including age, body mass index and the apnea-hypopnea index, in the obesity group. However, neither delta power nor total sleep time was associated with leptin in the non-obesity group. CONCLUSIONS Plasma leptin levels are independently associated with sleep quality in obese, but not in non-obese, type 2 diabetes patients. The present study indicates a favorable relationship between leptin and sleep quality in obese type 2 diabetes patients.

Abstract
AIMS To compare uric acid, lipid, and kidney profile along with management and complications of Indonesian diabetic patients with good and poor glycemic control based on glycated hemoglobin profile. MATERIALS AND METHODS Data was obtained from medical records of Internal Medicine Clinic in Hermina Podomoro General Hospital for the period January-December 2015. Subjects were grouped into good and poor glycemic control groups based on their glycated hemoglobin (HbA1c) levels. RESULTS Fifty-five subjects were obtained with an average age of 54 years, 29 with good glycemic control and 26 with poor glycemic control. All glycemic parameters were worse in poor compared to good glycemic control group (p < 0.05). Similar averages of urea, creatinine, uric acid, low-density lipoprotein (LDL) and a lower average of high-density lipoprotein (HDL) were found between both groups with statistically non-significant differences (p > 0.05). Main comorbidities were dyslipidemia, hypertension, and nephropathy. Fatty liver disease, urinary tract infection and neuropathy was also reported. Most patients were prescribed with oral anti-diabetics. CONCLUSION Diabetic patients regardless of glycemic control according to current guidelines have a greater average lipid and kidney profile than the optimum target. Therefore both are equally at greater risk for cardiovascular diseases, nephropathy, and other diabetic complications. Greater patient monitoring of these parameters is recommended to lower the risk of comorbidities and complications.

J Stroke Cerebrovasc Dis 2018; 27:2650-2656. [PMID: 29960667 DOI: 10.1016/j.jstrokecerebrovasdis.2018.05.032] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2017] [Revised: 05/17/2018] [Accepted: 05/22/2018] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Considerable researches suggest that high level of homocysteine (Hcy) is associated with the risk of ischemic stroke. Ambulatory blood pressure monitoring (ABPM) parameters have also been confirmed associated with cardio-cerebrovascular events. However, the relationship between Hcy and ABPM parameters remains unclear in patients with acute ischemic stroke. In this study, we aim to investigate the association between Hcy level and ABPM parameters in patients with acute ischemic stroke. METHODS We enrolled 60 patients with acute ischemic stroke who received ABPM. We calculated ABPM parameters like morning blood pressure surge (MBPS), ambulatory arterial stiffness index, blood pressure variability, and night dipping patterns. RESULTS Multivariate logistic regression analysis indicated that patients in the top quartile of Hcy level tended to have a higher level of prewaking and sleep-trough MBPS compared with patients in the lower 3 quartiles after adjusted for age and gender (P = .028 and P = .030, respectively). When treating Hcy as a continuous variable, the linear regression showed the association between Hcy level and both MBPS parameters remained significant (prewaking MBPS, r = .356, P = .022; sleep-trough MBPS, r = .365, P = .017, respectively). However, there is no association between Hcy level and ambulatory arterial stiffness index, blood pressure variability or night dipping patterns (P = .635, P = .348 and P = .127 respectively). CONCLUSIONS There is a relationship between the 2 major cerebrovascular risk factors: MBPS and Hcy.

Abstract
AIMS To investigate the loss of retinal nerve fiber layer (RNFL) in type-2 diabetic patients with early-stage diabetic retinopathy (DR) and to identify potential risk factors accounting for these alterations. METHODS In this cross-sectional study, 158 type-2 diabetic patients were divided into three groups based on their DR status. RNFL thickness and other optic disc parameters were obtained by optical coherence tomography (OCT) and then compared among different groups. We investigated the potential association between RNFL loss and systemic risk factors for DR, including diabetes duration, body mass index (BMI), serum lipids, hemoglobin A1c (HbA1c) and albumin-creatinine ratio (ACR). One-way ANOVA was carried out to compare RNFL thickness among different groups, Pearson correlation and multivariate linear regression analysis were performed to determine potential risk factors related to RNFL thickness in these patients. RESULTS There were significant differences in the average (F = 8.872, P = 0.003), superior (F = 8.769, P = 0.004), and inferior (F = 8.857, P = 0.003) RNFL thickness of both eyes among the groups, but no obvious difference in optic disc parameters was found. Diabetic duration, BMI, TG, High density lipoprotein cholesterol (HDL), HbA1c, and ACR were found negatively related to the RNFL thickness in both or single eye according to Pearson correlation analysis. After controlling for age, gender, and axis length (AL) in multivariate linear regression analysis, the diabetic duration was associated significantly with RNFL thickness of superior in both eye (right eye: p = 0.016, left eye: p = 0.024), BMI was related to the nasal quadrant of the right eye (p = 0.034), and TG was related to the inferior of the right eye (p = 0.037), HbA1c (p = 0.026) was associated significantly with the average RNFL thickness of the right eye. In addition, ACR was found negatively related to average (p = 0.042) and inferior quadrant (p = 0.014) of the left eye, respectively. CONCLUSIONS RNFL loss might be the earliest structural change of retina in diabetic patients, and associated with diabetic duration, BMI, TG, HbA1c, and ACR. The conclusions of this study need to be proved by other well-matched and large-scale prospective clinical trials in the future, because the correlations discovered in our study were weak.

Abstract
BACKGROUND Type 2 diabetic patients display significantly higher incidence of cardiovascular (CV) events including stroke compared to non-diabetics. Morning blood pressure surge (MBPS) and blunted systolic night-day (SND) ratio have been associated with CV events in hypertensive patients. No studies have evaluated MBPS in newly diagnosed diabetic patients or studied the association with vascular target organ damage at this early time point of the diabetes disease. METHODS Ambulatory blood pressure monitoring was performed in 100 patients with newly diagnosed type 2 diabetes and 100 age and sex matched controls. MBPS and SND-ratio were calculated. Markers of early vascular target organ damage included pulse wave velocity (PWV), white matter lesions (WML) on brain MRI, and urine albumin/creatinine ratio (UAE). RESULTS No significant differences in MBPS were found between diabetic patients and controls. Neither MBPS or SND-ratio were associated with PWV, UAE or WML in the diabetic group independently of age, gender and 24-h systolic blood pressure. 40.2 % of diabetic patients and 25.8 % of controls were classified as non-dippers (p = 0.03). CONCLUSION MBPS and SND-ratio are not associated with subclinical markers of vascular target organ damage in our study sample of newly diagnosed type 2 diabetic patients.

Abstract
Morning hypertension (HTN) and nocturnal non-dipping (ND) are closely associated with target organ damage and cardiovascular events. However, their importance in diabetics with advanced renal disease is unclear. We evaluated the relationships of morning HTN and ND with estimated glomerular filtration rate (eGFR) and proteinuria, and determined the risk of morning HTN and ND according to presence of diabetes mellitus (DM) and chronic kidney disease (CKD) stage. A total of 1312 patients, including 439 with diabetes, were prospectively recruited at 21 centers in Korea. All patients had HTN and an eGFR of 15-89 ml min(-1) per 1.73 m(2). Ambulatory 24-h blood pressure was assessed. The rates of morning HTN (25.2% vs. 13.6%, P<0.001) and ND (58.2% vs. 48.2%, P=0.002) were higher in diabetics than in non-diabetics. eGFR was correlated with ND in all patients (P<0.05) and with morning HTN only in non-diabetics (P=0.005). Proteinuria was related to ND in all patients (P<0.05) and to morning HTN only in diabetics (P=0.001). In a regression analysis, the risk of morning HTN was 2.093 (95% confidence interval (95% CI): 1.070-4.094) for the DMCKD2 group, 1.634 (95% CI: 1.044-2.557) for the CKD3-4-only group and 2.236 (95% CI: 1.401-3.570) for the DMCKD3-4 group compared with the CKD2-only group. The risk of ND was high for stage 3-4 CKD: 1.581 (95% CI: 1.180-2.120) for non-diabetics and 1.842 (95% CI: 1.348-2.601) for diabetics. Diabetics showed higher rates of morning HTN, ND and uncontrolled sustained HTN compared with non-diabetics with CKD of the same stages.

Abstract
Objective Poor sleep quality is an independent predictor of cardiovascular events. However, little is known about the association between glycemic control and objective sleep architecture and its influence on arteriosclerosis in patients with type-2 diabetes mellitus (DM). The present study examined the association of objective sleep architecture with both glycemic control and arteriosclerosis in type-2 DM patients. Design Cross-sectional study in vascular laboratory. Methods The subjects were 63 type-2 DM inpatients (M/F, 32/31; age, 57.5±13.1) without taking any sleeping promoting drug and chronic kidney disease. We examined objective sleep architecture by single-channel electroencephalography and arteriosclerosis by carotid-artery intima-media thickness (CA-IMT). Results HbA1c was associated significantly in a negative manner with REM sleep latency (interval between sleep-onset and the first REM period) (β=-0.280, p=0.033), but not with other measurements of sleep quality. REM sleep latency associated significantly in a positive manner with log delta power (the marker of deep sleep) during that period (β=0.544, p=0.001). In the model including variables univariately correlated with CA-IMT (REM sleep latency, age, DM duration, systolic blood pressure, and HbA1c) as independent variables, REM sleep latency (β=-0.232, p=0.038), but not HbA1c were significantly associated with CA-IMT. When log delta power was included in place of REM sleep latency, log delta power (β=-0.257, p=0.023) emerged as a significant factor associated with CA-IMT. Conclusions In type-2 DM patients, poor glycemic control was independently associated with poor quality of sleep as represented by decrease of REM sleep latency which might be responsible for increased CA-IMT, a relevant marker for arterial wall thickening.

Abstract
AIMS The current study aimed to investigate the relationship between morning blood pressure surge (MBPS), hemodynamic parameters, glycemic control and 24-h urinary sodium excretion (USE) in patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS MBPS and central hemodynamic parameters were assessed from ambulatory blood pressure measurements. In addition to routine biochemistry, 24h urine collection was performed to measure protein, albumin and sodium excretion. RESULTS There were 146 (38%) patients with T2DM and 238 (72%) patients without T2DM (control group). Patients with T2DM had statistically higher MBPS compared with patients without T2DM (P<0.0001). In patients with T2DM, MBPS was correlated with HbA1c (rho=0.311, P<0.0001), 24h urinary sodium excretion (USE) (rho=0.292, P=0.004) and various hemodynamic parameters. Additionally, regression analysis showed that being male (P=0.006), the presence of coronary artery disease (P=0.023), HbA1c (P=0.012), and 24h USE (P=0.001) were independently related with log MBPS in T2DM patients. CONCLUSION This study demonstrated that T2DM was an independent risk factor for increased MBPS and MBPS was associated with central hemodynamic parameters. Additionally poor glycemic control and sodium intake were associated with worse MBPS in T2DM.
