Abstract
Extreme cold exposure has been widely considered as a cardiac stress and may result in cardiac function decompensation. This study was to examine the risk factors that contribute to changes in cardiovascular indicators of cardiac function following extreme cold exposure and to provide valuable insights into the preservation of cardiac function and the cardiac adaptation that occur in real-world cold environment. Seventy subjects were exposed to cold outside (Mohe, mean temperature -17 to -34°C) for one day, and were monitored by a 24-h ambulatory blood pressure device and underwent echocardiography examination before and after extreme cold exposure. After exposure to extreme cold, 41 subjects exhibited an increase in ejection fraction (EF), while 29 subjects experienced a decrease. Subjects with elevated EF had lower baseline coefficients of variation (CV) in blood pressure compared to those in the EF decrease group. Additionally, the average real variability (ARV) of blood pressure was also significantly lower in the EF increase group. Multivariate regression analysis indicated that both baseline CV and ARV of blood pressure were independent risk factors for EF decrease, and both indicators proved effective for prognostic evaluation. Correlation analysis revealed a correlation between baseline blood pressure CV and ARV, as well as EF variation after exposure to extreme cold environment. Our research clearly indicated that baseline cardiovascular indicators were closely associated with the changes in EF after extreme cold exposure. Furthermore, baseline blood pressure variability could effectively predict alterations in left cardiac functions when individuals were exposed to extreme cold environment.

Increased Blood Pressure Variability Over a 16-Year Period Is Associated With Left Ventricular Diastolic Dysfunction in a Population-Based Cohort. Am J Hypertens 2024; 37:168-178. [PMID: 37944035 DOI: 10.1093/ajh/hpad106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/18/2023] [Accepted: 10/30/2023] [Indexed: 11/12/2023] Open
Abstract
BACKGROUND Left ventricular diastolic dysfunction (LVDD) is often associated with elevated blood pressure (BP). It is prevalent among hypertensive patients. Additionally, increased BP variability has been linked to LVDD. However, the precise connection between LVDD and BP variability within the general population remains unclear. Thus, this study aimed to evaluate this association in a general population. METHODS A total of 2,578 participants(1,311 females) with a mean age of 47.8 ± 6.7 years who had echocardiographic data from the Korean Genome and Epidemiology study with 16 years of follow-up were analyzed. LVDD was identified through the last echocardiography during the follow-up period. BP variability was assessed using mean, standard deviation (SD), and coefficient of variance (CV). RESULTS LVDD was detected in 249 individuals. The cohort was divided into an LVDD group and a normal LV diastolic function group. The LVDD group had a higher percentage of females, more advanced age, higher body mass index (BMI), higher BP and BUN levels, lower heart rate, lower hemoglobin, and lower serum creatinine than the normal LV diastolic function group. Remarkably, LVDD was associated with higher BP variability. In the multivariate analysis, LVDD was associated with increased age, female sex, increased BMI, hypertension, and increased BUN. Elevated mean systolic and diastolic BPs, SD of systolic BP, mean pulse pressure (PP), SD of PP, and CV of PP were significantly linked to LVDD even after adjusting for other significant variables in the multivariate analysis. CONCLUSIONS LVDD was identified in 249 (9.7%) participants. Increased long-term BP variability was significantly associated with LVDD in this population-based cohort.

Abstract
Blood pressure is not a static parameter, but rather undergoes continuous fluctuations over time, as a result of the interaction between environmental and behavioural factors on one side and intrinsic cardiovascular regulatory mechanisms on the other side. Increased blood pressure variability (BPV) may indicate an impaired cardiovascular regulation and may represent a cardiovascular risk factor itself, having been associated with increased all-cause and cardiovascular mortality, stroke, coronary artery disease, heart failure, end-stage renal disease, and dementia incidence. Nonetheless, BPV was considered only a research issue in previous hypertension management guidelines, because the available evidence on its clinical relevance presents several gaps and is based on heterogeneous studies with limited standardization of methods for BPV assessment. The aim of this position paper, with contributions from members of the European Society of Hypertension Working Group on Blood Pressure Monitoring and Cardiovascular Variability and from a number of international experts, is to summarize the available evidence in the field of BPV assessment methodology and clinical applications and to provide practical indications on how to measure and interpret BPV in research and clinical settings based on currently available data. Pending issues and clinical and methodological recommendations supported by available evidence are also reported. The information provided by this paper should contribute to a better standardization of future studies on BPV, but should also provide clinicians with some indications on how BPV can be managed based on currently available data.

Abstract
OBJECTIVE We sought to examine the relationship between visit-to-visit variability of SBP and incident atrial fibrillation in middle-aged and older population. METHODS This prospective cohort study included 26 999 participants aged 50 years or older at study entry. Visit-to-visit variability of SBP was defined as the average real variability (ARV) of three values of SBP from the examinations of 2006, 2008, and 2010. We categorized participants into four groups according to the quartiles of ARV. Incident atrial fibrillation cases were identified via ECG during biennial resurveys, and reviewing medical insurance record and discharge registers. We used Cox regression models to evaluate the hazard ratios and 95% confidence intervals (CI) for incident atrial fibrillation. RESULTS After an average follow-up of 9.24 years, a total of 420 atrial fibrillation cases were identified. The incidence of atrial fibrillation from the lowest to the highest quartiles of SBP variability were 1.23, 1.53, 1.81 and 2.19 per 1000 person-years, respectively. After adjusting for potential confounders, including mean blood pressure, we found a graded association between SBP variability and risk of atrial fibrillation. Participants in the third quartile and the highest quartile were associated with 35 and 53% higher risk of developing atrial fibrillation, respectively, compared with participants in the lowest quartile [hazard ratio (95% CI), 1.35 (1.01-1.82) and 1.53 (1.15-2.04)]. The results persisted across sensitivity analyses. CONCLUSION Increased visit-to-visit variability of SBP is a strong predictor of incident atrial fibrillation in middle-aged and older population. Evaluation of long-term SBP variability could help to identify individuals at higher risk of atrial fibrillation.

Abstract
BACKGROUND Increased blood pressure (BP) variability is positively associated with the risks of cerebral small-vessel disease, cardiovascular events and death. However, no large clinical trials have been published to demonstrate the effect of BP fluctuations during hospitalization on clinical outcomes after ischemic stroke. METHODS A total of 3972 patients with acute ischemic stroke from 26 participating hospitals were included in this study, and BP fluctuations were calculated using BP data collected during the hospitalization. The primary outcome was composite outcome of death or major disability (modified Rankin Scale score ≥3) within 3 months and secondary outcomes included death, vascular events, and composite outcomes (death or vascular events). RESULTS Compared with the lowest quartile of systolic BP fluctuations, the adjusted odds ratio associated with the highest quartile was 1.33 ([95% CI, 1.05-1.68]; Ptrend=0.011) for primary outcome; the adjusted hazard ratios were 2.89 ([95% CI, 1.58-5.32]; Ptrend<0.001) for death, 1.48 ([95% CI, 0.83-2.65]; Ptrend=0.071) for vascular events, and 2.06 ([95% CI, 1.32-3.23]; Ptrend<0.001) for composite outcome. Similar results were found for diastolic BP. Multivariable adjusted restricted cubic spline analysis showed a linear relationship between systolic BP fluctuations and the primary outcome (P for linearity=0.0009). CONCLUSIONS Larger BP fluctuations during hospitalization were associated with an increased risk of adverse outcomes at 3 months after ischemic stroke onset, independent of mean BP. These findings suggested that BP fluctuation should be a risk factor of adverse outcomes after ischemic stroke, which provided a new insight for BP management strategy.

Abstract
OBJECTIVES As there is uncertainty about the extent to which baseline blood pressure level or cardiovascular risk modifies the relationship between blood pressure variability (BPv) and cardiovascular disease, we comprehensively examined the role of BPv in cardiovascular disease risk in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) Trial. METHODS Using data from ACCORD, we examined the relationship of BPv with development of the primary CVD outcome, major coronary heart disease (CHD), and total stroke using time-dependent Cox proportional hazards models. RESULTS BPv was associated with the primary CVD outcome and major CHD but not stroke. The positive association with the primary CVD outcome and major CHD was more pronounced in low and high strata of baseline SBP (<120 and >140 mmHg) and DBP (<70 and >80 mmHg). The effect of BPv on CVD and CHD was more pronounced in those with both prior CVD history and low blood pressure. Dips, not elevations, in blood pressure appeared to drive these associations. The relationships were generally not attenuated by adjustment for mean blood pressure, medication adherence, or baseline comorbidities. A sensitivity analysis using CVD events from the long-term posttrial follow-up (ACCORDION) was consistent with the results from ACCORD. CONCLUSION In ACCORD, the effect of BPv on adverse cardiovascular (but not cerebrovascular) outcomes is modified by baseline blood pressure and prior CVD. Recognizing these more nuanced relationships may help improve risk stratification and blood pressure management decisions as well as provide insight into potential underlying mechanisms.

Abstract
Importance Long-term blood pressure (BP) variability has emerged as a reproducible measure that is associated with heart failure independent of systemic BP. Visit-to-visit BP variability may be associated with the risk of heart failure early in the life course and thus may be reflected in subclinical alterations in cardiac structure and function. Objective To evaluate the association between visit-to-visit BP variability in early adulthood and myocardial structure and function in middle age. Design, Setting, and Participants This cohort study used data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a community-based cohort study of 5115 participants aged 18 to 30 years at baseline (year 0; March 25, 1985, to June 7, 1986) and followed up over a 30-year interval. A total of 2400 CARDIA study participants underwent evaluation at 4 field sites (Birmingham, Alabama; Oakland, California; Chicago, Illinois; and Minneapolis, Minnesota). Blood pressure was measured at 8 visits over a 25-year interval and participants received echocardiograms at year 25 (June 1, 2010, to August 31, 2011). Data analysis was conducted from June 7, 1986, to August 31, 2011. Exposures Visit-to-visit systolic and diastolic BP variability measures included SD, average real variability, and variability independent of the mean. Main Outcomes and Measures Echocardiographic indices of myocardial structure, systolic function, and diastolic function at the year 25 examination. Results Of the 2400 participants, 1024 were men (42.7%) and 976 were African American (40.7%); mean (SD) age at the year 25 examination was 50.4 (3.6) years. Per 1-SD increment, greater visit-to-visit systolic BP variability independent of the mean was associated with higher left-ventricular (LV) mass index (β [SE], 2.66 [0.4] g/m2, P < .001), worse diastolic function (early peak diastolic mitral annular velocity [é]) (β [SE], -0.40 [0.1] cm/s, P < .001), higher LV filling pressures (mitral inflow velocity to early diastolic mitral annular velocity [E/é]) β [SE], 0.37 [0.1] cm/s, P < .001), and worse global longitudinal strain (β [SE], 0.17 [0.1], P = .002). Similarly, greater visit-to-visit diastolic BP variability was associated with higher LV mass index (β [SE], 3.21 [0.5] g/m2, P < .001), worse diastolic function (é: β [SE], -0.24 [0.1] cm/s [P < .001]; E/é: β [SE], 0.23 [0.1] cm/s [P < .001]), and worse global longitudinal strain (β [SE], 0.13 [0.1], P = .02). The findings remained consistent when other BP variability measures were used (SD and average real variability). Conclusions and Relevance In this cohort study using data from the CARDIA study, greater visit-to-visit systolic and diastolic BP variability have been associated with adverse alterations in cardiac structure as well as systolic and diastolic function independent of mean BP levels.

Higher visit-to-visit blood pressure variability and N-terminal pro-brain natriuretic peptide elevation: influence of left ventricular hypertrophy and left ventricular diastolic function. Blood Press Monit 2020; 25:126-130. [PMID: 32187034 DOI: 10.1097/mbp.0000000000000441] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/10/2023]
Abstract
OBJECTIVE The issue of whether visit-to-visit blood pressure variability (VVV) is associated with higher levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) has been controversial, and the underlying mechanism is not well understood. We hypothesized that (1) VVV is associated with the NT-proBNP level, and (2) this association is mediated by left ventricular (LV) hypertrophy and LV diastolic dysfunction. PATIENTS AND METHODS A total of 72 hypertensive patients were examined. Clinic blood pressure was measured at each visit for 12 months (1×/month or every 2 months), and echocardiography was performed during this period. VVV is expressed as the SD, coefficient of variation (CV), and delta (Δ; the difference between the maximum and the minimum) in SBP and in DBP. We investigated the association between VVV and NT-proBNP and whether the LV mass index (LVMI) and the mitral early diastolic inflow velocity (E) to mitral annular early-diastolic peak velocity (e') ratio (E/e') influence this association. RESULTS The loge NT-proBNP values were significantly correlated with the CV of SBP (r = 0.42), ΔSBP (r = 0.41), the CV of DBP (r = 0.32), and ΔDBP (r = 0.28). The CV and Δ in SBP or those in DBP were not significantly correlated with LVMI or E/e'. A multiple linear regression analysis revealed that higher CV of SBP and ΔSBP were significantly associated with loge NT-proBNP. CONCLUSION Higher VVV was significantly associated with higher NT-proBNP independently of LV hypertrophy and diastolic function.

Abstract
BACKGROUND Rapid kidney decline is associated with mortality and cardiovascular disease, even in the absence of chronic kidney disease. American Indians (AI) have particularly high burden of kidney disease, cardiovascular disease, and stroke. This study aims to examine extreme loss in glomerular function in this population in association with clinical outcomes. METHODS The Strong Heart Study, a large longitudinal cohort of adult AI participants, collected plasma creatinine at 3 examination visits between 1989-1999. Intraindividual regressions of estimated glomerular filtration rate (eGFR) provided linear estimates of change in kidney function over this time period. Surveillance with physician adjudication identified mortality and cardiovascular events between visit 3 through 2017. RESULTS Mean change in eGFR was loss 6.8 mL/min over the ten year baseline (range: -66.0 to +28.9 mL/min). The top 1 percentile lost approximately 5.7 mL/min/year. Participants with extreme eGFR loss were more likely to have diabetes (95% vs 71%), hypertension (49% vs 33%), or longer smoking history, among smokers (19 pack years vs 17 pack years). CKD (eGFR<60 mL/min) was associated only with mortality, independent of slope: HR 1.1 (95% CI 1.0-1.3). However, extreme loss in eGFR (>20 mL/min over baseline period) was associated with mortality, independent of baseline eGFR: HR 3.5 (95% CI 2.7-4.4), and also independently associated with composite CVD events and CHF: HR 1.4 and 1.7 (95% CI 1.1-1.9 and 1.2-2.6), respectively. CONCLUSION This is the first examination of decline in eGFR in association with mortality and CVD among AIs. The implications of these findings are broad: clinical evaluation may benefit from evaluating change in eGFR over time in addition to dichotomous eGFR. Also, these findings suggest there may be aspects of renal function that are not well-marked by clinical CKD, but which may have particular relevance to long-term renal and vascular health.

Abstract
Recent evidence links long-term (visit-to-visit) blood pressure (BP) variability to the risk of cardiovascular disease, independent of mean BP levels. Potential associations between long-term BP variability and cardiovascular disease risk may be reflected in early life course alterations in coronary artery calcium (CAC) and carotid intima-media thickness. We evaluated 2482 CARDIA study (Coronary Artery Risk Development in Young Adults) participants (mean [SD] age at the year 20 exam [2005-2006] was 45.4 [3.6] years, 43.2% men, and 41.3% black). We included participants with BP assessments across 20-years (year 0, 2, 5, 7, 10, 15, 20 exams) and carotid intima-media thickness and CAC data at the year 20 exam. BP variability was assessed using variability independent of the mean and SD. Adjusted multivariable linear or logistic regression models (as appropriate) were used to assess associations between long-term BP variability measures and carotid intima-media thickness. and CAC (ln [CAC+1] and prevalent CAC). Long-term systolic BP variability independent of the mean (per 1 SD) was positively associated with carotid intima-media thickness (β=10 μm, SE=3, P=0.002). Similarly, long-term diastolic BP variability independent of the mean was associated with carotid intima-media thickness (β=10 μm, SE (3), P=0.001). Long-term BP variability was not associated with either ln [CAC+1] or prevalent CAC. Long-term systolic and diastolic BP variability across early adulthood was positively associated with modest adverse midlife alterations in carotid intima-media thickness but not to CAC. Our findings provide further insights into pathophysiologic mechanisms that link long-term BP variability to cardiovascular disease.

Abstract
Earlier studies have shown that visit-to-visit blood pressure (BP) variability (VVV) served as a significant independent risk factor of stroke, specifically, in the high-risk elderly of cardiovascular disease (CVD). Although the mechanism is not clearly understood, arterial remodeling such as carotid artery, coronary artery and large aortic artery would be a strong moderator in the relationship between VVV and CVD incidence. Recent studies have provided evidence that VVV predicted the progression of arterial stiffness. While the class of antihypertensive agents is suggested to be an important determinant of VVV, long-acting calcium channel blockers use (CCBs) is associated with the reduction of VVV, and thus, is suggested to decrease the arterial stiffness. Specifically, the relationship between VVV and coronary arterial remodeling has never been reviewed until now. This article summarizes the recent literature on these topics. In the elderly hypertensives, strict BP control using CCBs could play a pivotal role in suppressing arterial stiffening via VVV reduction.

Factors associated with intra-individual visit-to-visit variability of blood pressure in four countries: the INTERMAP study. J Hum Hypertens 2018; 33:229-236.

Abstract
Several studies demonstrated that visit-to-visit variability of blood pressure (BP) predicted future events of total death, stroke and cardiovascular disease. Little is known about factors associated with visit-to-visit BP variability in different countries. We recruited participants aged 40-59 years from four countries (Japan, the People's Republic of China [PRC], the United Kingdom [UK] and the United States [US]). At each study visit, BP was measured twice by trained observers using random zero sphygmomanometers after five minutes resting. We defined visit-to-visit BP variability as variation independent of mean (VIM) by using average systolic BP of 1st and 2nd measurement across four study visits. Data on 4680 men and women were analyzed. Mean ± standard deviation of VIM values among participants in Japan, the PRC, the UK and the US were 5.44 ± 2.88, 6.85 ± 3.49, 5.65 ± 2.81 and 5.84 ± 3.01, respectively; VIM value in the PRC participants was significantly higher. Sensitivity analyses among participants without antihypertensive treatment or past history of cardiovascular disease yielded similar results. Higher VIM value was associated with older age, female gender, lower pulse rate and urinary sodium excretion and use of antihypertensive agents such as angiotensin converting enzyme inhibitors, beta blockers and calcium channel blockers. The difference of visit-to-visit BP variability between PRC and other countries remained significant after adjustment for possible confounding factors. In this large international study across four countries, visit-to-visit BP variability in the PRC was higher than in the other three countries. Reproducibility and mechanisms of these findings remain to be elucidated.

Abstract
Aims To investigate the relationship between visit-to-visit blood pressure variability (BPV) and the progression of both carotid and coronary artery disease (CAD). Methods and results Data from two cardiovascular endpoint studies [Norvasc for Regression of Manifest Atherosclerotic Lesions by Intravascular Sonographic Evaluation (NORMALISE) and Prospective Randomized Evaluation of the Vascular Effects of Norvasc Trial (PREVENT)] were analysed separately. Systolic BPV was assessed as within-subject standard deviation of systolic BP across visits from 12-weeks onwards. Follow-up was 24 months (NORMALISE) or 36 months (PREVENT). Any association between BPV and progression of atherosclerosis was assessed using quantitative coronary angiography (QCA), intravascular ultrasound (IVUS), or B-mode ultrasound (depending on study). Patients from NORMALISE (n = 261) and PREVENT (n = 688 for QCA; n = 364 for ultrasound) were stratified within study according to median systolic BPV. No significant difference in change of minimal luminal diameter (by QCA in PREVENT) or change in percent atheroma volume or normalized total atheroma volume (by IVUS in NORMALISE) was detected for subjects with low BPV (BPV < median) compared with high BPV (BPV ≥ median), regardless of treatment. In PREVENT, a significantly greater reduction in maximum carotid intima-media thickness (IMT) (left and right common carotid artery far wall) was observed for patients with BPV < median compared with those with BPV ≥ median [least squares mean difference 0.06 (95% confidence interval 0.01, 0.11); P = 0.0271], after adjusting for treatment, carotid artery segment (left or right), baseline maximum carotid IMT, and other baseline and cardiovascular risk factors/covariates. Conclusions In patients with existing CAD and well-controlled BP, visit-to-visit BPV was not associated with progression of coronary atherosclerosis; however, a significantly greater reduction in maximum carotid IMT was observed for patients with low BPV.

Abstract
Background To evaluate association of 24 h–systolic blood pressure (SBP) variability and obstructive sleep apnea (OSA) as defined by the apnea-hypopnea index ≥5/h; and association of 24 h–SBP variability and prevalent cardiovascular disease (CVD) in OSA patients. Methods Participants underwent polysomongraphy to evaluate the presence of OSA, and 24 h–ambulatory blood pressure monitoring was applied to evaluate 24 h–SBP variability as indexed by weighted 24 h–standard deviation (SD) of SBP. Between-group differences were evaluated in participants with and without OSA. Participants with OSA were divided into high and low 24 h–SBP variability groups and between-group differences were evaluated. Results Mean age of 384 participants was 50 years old and 42.2% had OSA. Mean 24 h–systolic/diastolic BP were 130/78 mmHg, with mean weighted 24 h–SD of systolic/diastolic BP were 12.9/7.3 mmHg. Compared to those without OSA, OSA participants had higher clinic-, 24 h-, daytime- and nighttime-SBP, and weighted 24 h, daytime- and nighttime-SD of SBP. Age, prevalent CVD and OSA, usage of angiotensin converting enzyme inhibitor/angiotensin receptor blocker, calcium channel blocker and diuretic were significantly associated with 24 h–SBP variability. In OSA patients, compared to those with low variability, participants with high variability had higher weighted 24 h, daytime- and nighttime-SD of SBP. After adjusted for covariates including clinic-SBP and 24 h–SBP, per 1-SD increment weighted 24 h–SD of SBP was associated with 21% increased prevalent CVD. Conclusions Patients with newly-diagnosed OSA have higher 24 h–SBP variability compared to those without OSA; in OSA patients, increased 24 h–SBP variability is associated with increased prevalence of CVD.

Abstract
BACKGROUND Blood pressure (BP) is associated with carotid intima-media thickness (CIMT), but few studies have explored the association between BP variability and CIMT. We aimed to investigate this association in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline. METHODS We analyzed data from 7,215 participants (56.0% women) without overt cardiovascular disease (CVD) or antihypertensive use. We included 10 BP readings in varying positions during a 6-hour visit. We defined BP variability as the SD of these readings. We performed a 2-step analysis. We first linearly regressed the CIMT values on main and all-order interaction effects of the variables age, sex, body mass index, race, diabetes diagnosis, dyslipidemia diagnosis, family history of premature CVD, smoking status, and ELSA-Brasil site, and calculated the residuals (residual CIMT). We used partial least square path analysis to investigate whether residual CIMT was associated with BP central tendency and BP variability. RESULTS Systolic BP (SBP) variability was significantly associated with residual CIMT in models including the entire sample (path coefficient [PC]: 0.046; P < 0.001), and in women (PC: 0.046; P = 0.007) but not in men (PC: 0.037; P = 0.09). This loss of significance was probably due to the smaller subsample size, as PCs were not significantly different according to sex. CONCLUSIONS We found a small but significant association between SBP variability and CIMT values. This was additive to the association between SBP central tendency and CIMT values, supporting a role for high short-term SBP variability in atherosclerosis.

Abstract
BACKGROUND This study aimed to investigate the association between variability in hemoglobin A1c (HbA1c) and left ventricular (LV) diastolic function and incidence of symptomatic heart failure with preserved ejection fraction (HFpEF) in patients with type 2 diabetes mellitus (T2DM) and arterial hypertension. METHODS A retrospective cohort study was conducted on eligible patients with T2DM and hypertension and without clinical signs or symptoms of heart failure in our hospital medical record database. Variability in HbA1c was measured by standard deviation (SD) and coefficient of variation (CV). Risk of new onset of symptomatic HFpEF was evaluated by multivariable cox regression analysis. RESULTS A total of 201 subjects were categorized according to the median value of HbA1c variability indicators. Over a median follow-up of 7.3 years, the percentage of subjects who had new incidence of symptomatic HFpEF was higher in those with higher HbA1c-SD level (5/105 vs. 13/96, P=0.029) and higher HbA1c-CV level (5/101 vs. 13/100, P=0.046). Multivariable cox regression analysis also showed that higher HbA1c variability [HbA1c-SD (HR 1.754, 95% CI: 1.003-3.104, P=0.049) or HbA1c-CV (HR 1.604 95% CI: 1.064-2.419, P=0.024)] was associated with the presence of new-onset symptomatic HFpEF, independent of HbA1c-mean level, in T2DM and hypertensive patients. Moreover, lower HbA1c variability generated more prominent improvement in LV diastolic function (E/E') during the follow-up. CONCLUSIONS HbA1c variability may provide additional valuable information as a potential predictor of the progression of HFpEF in T2DM and hypertensive patients.

Abstract
BACKGROUND The visit-to-visit variability in blood pressure (BP) has been shown to be a strong predictor of cardiovascular events. It is not known whether anti-hypertensive therapy using a single-pill fixed-dose combination of angiotensin II receptor blocker (ARB)/calcium channel blocker (CCB) or ARB/diuretic (DI) in hypertensive patients affects the visit-to-visit variability and seasonal variation of BP. METHODS We enrolled 47 hypertensive patients who had received a single-pill fixed-dose combination of either ARB/CCB (n = 30) or ARB/DI (n = 17) for 15 months. Beginning 3 months after the start of ARB/CCB or ARB/DI treatment, we determined the visit-to-visit variability in BP expressed as the standard deviation (SD) of average BP and the seasonal variation in BP expressed as the SD of average BP in each season (spring, summer, fall and winter were defined as lasting from March to May, June to August, September to November and December to February, respectively) for a year. RESULTS There were no significant differences in baseline patient characteristics except for the prevalence of coronary artery disease and the percentage of CCB excluding amlodipine in the ARB/CCB group between the ARB/CCB and ARB/DI groups. There were no significant differences in the 1-year time course of systolic and diastolic BP (SBP and DBP) between the groups, although there were significant differences in SBP in August and November and DBP in December. Interestingly, the visit-to-visit variability and seasonal variation of BP in the ARB/CCB group were similar to those in the ARB/DI group. CONCLUSION Single-pill fixed-dose combinations of ARB/CCB and ARB/DI had similar effects on visit-to-visit variability and seasonal variation in BP in hypertensive patients.
