RESUMEN
AIM: We investigated whether the Dementia Assessment Sheet for Community-based Integrated Care System-21 Items (DASC-21), a questionnaire that assesses cognitive function, including activities of daily living (ADL), was predictive of in-hospital death and prolonged hospital stay in elderly patients hospitalized for heart failure. METHODS: We retrospectively assessed the DASC-21 score at the time of admission, in-hospital death, length of hospital stay, and change in the Barthel index in 399 patients hospitalized for heart failure between 2016 and 2019. RESULTS: The mean patient age was 85.8 ± 7.7 years (61.3% women). The median DASC-21 score was 38 (64.7% higher than 31). On multivariate logistic regression analysis, a higher DASC-21 score was associated with an increased risk of in-hospital death (odds ratio [OR] = 1.045 per 1 point increase, 95% confidence interval [CI]: 1.010-1.081, P = 0.012), even after adjusting for confounding factors, including atrial fibrillation, ejection fraction, and B-type natriuretic peptide. Difficulties (3 or 4) with the self-management of medication in instrumental ADL inside the home (OR = 3.28, 95% CI: 1.05-10.28, P = 0.042), toileting (OR = 3.66, 95% CI: 1.19-11.29, P = 0.024), grooming (OR = 6.47, 95% CI: 2.00-20.96, P = 0.002), eating (OR = 7.96, 95% CI: 2.49-25.45, P < 0.001), and mobility in physical ADL (OR = 5.99, 95% CI: 1.85-19.35, P = 0.003) were identified as risk factors for in-hospital death. Patients in the highest tertile of the DASC-21 score had a significantly longer hospital stay (P = 0.006) and a greater reduction in the Barthel index (P < 0.001). CONCLUSIONS: In elderly patients hospitalized for heart failure, higher DASC-21 scores were associated with an increased risk of in-hospital death, prolonged hospital stay, and impaired ADL.

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) with renal dysfunction (RD) is considered to be a specific phenotype of HFpEF. This study aimed to compare the clinical characteristics and prognostic factors for in-hospital mortality between HFpEF-diagnosed patients with and without RD. METHODS: This multicenter retrospective study included 5867 consecutive patients with acute HFpEF. RD was defined by an estimated glomerular filtration rate (eGFR) of <60 mL/min per 1.73 m2. Kaplan-Meier survival curves and log-rank tests were used to compare the in-hospital mortality between the groups. Univariable and multivariable Cox regression analyses were performed to identify significant prognostic factors. RESULTS: Across the study cohort, 68% of patients had RD. In-hospital mortality was significantly higher in HFpEF patients with RD than in those without RD. The comorbidities and laboratory data differed significantly between the groups. Independent prognostic factors for in-hospital mortality in the HFpEF patients with RD were age (hazard ratio [HR], 1.039), systolic blood pressure (HR, 0.991), eGFR (HR, 0.981), C-reactive protein (CRP; HR, 1.028), diuretics (HR, 0.374), angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACE-I/ARBs; HR, 0.680), and beta-blockers (HR, 0.662). In HFpEF patients without RD, age (HR, 1.039), systolic blood pressure (HR, 0.979), and ACE-I/ARBs (HR, 0.373) were independent prognostic factors. CONCLUSIONS: Significant differences in the clinical characteristics and prognostic factors, such as CRP and beta-blockers, were observed between the HFpEF patients with and without RD. These results have implications for future research and may help guide individualized patient management strategies.
RESUMEN
This study aimed to evaluate the relationship between pulse pressure (PP) and sarcopenia, frailty, and cognitive function in elderly patients with hypertension. We evaluated 435 elderly patients with a history of hypertension who visited the frail outpatient clinic between July 2015 and October 2021. Data at the 1-, 2-, and 3-year follow-ups were available for 222, 177, and 164 patients, respectively. Sarcopenia, frailty, and cognitive function, including Mini-Mental State Examination (MMSE) scores, were evaluated. The patients' mean age was 79.2 ± 6.3 years (male, 34.9%). PP and mean blood pressure (BP) were 60.1 ± 13.6 mmHg and 94.1 ± 13.0 mmHg, respectively. At baseline, lower PP was associated with probable dementia (MMSE score ≤23 points) (OR = 0.960 per 1 mmHg increase; 95% CI, 0.933-0.989; P = 0.006) in the model adjusted for conventional confounding factors and comorbidities, whereas higher PP was associated with low handgrip strength (OR = 1.018 per 1 mmHg increase; 95% CI, 1.001-1.036; P = 0.041). In multivariate-adjusted logistic regression analysis of patients with preserved handgrip strength at baseline, reductions in PP (OR = 0.844; 95% CI, 0.731-0.974; P = 0.020) and mean BP (OR = 0.861; 95% CI, 0.758-0.979; P = 0.022) were significantly associated with the incidence of low handgrip strength at 3 years. In conclusion, a higher PP induced by increased arterial stiffness was associated with lower handgrip strength, whereas a lower PP was associated with probable dementia. Reduced PP was associated with decreased handgrip strength after three years.

BACKGROUND AND AIMS: Diabetic cardiomyopathy refers to cases of diabetes mellitus (DM) complicated by cardiac dysfunction in the absence of cardiovascular disease and hypertension. Its epidemiology remains unclear due to the high rate of coexistence between DM and hypertension. Therefore, this study aimed to examine the prevalence and clinical characteristics of diabetic cardiomyopathy among patients with acute heart failure (HF). METHODS AND RESULTS: This multicenter, retrospective study included 17,614 consecutive patients with acute HF. DM-related HF was defined as HF complicating DM without known manifestations of coronary artery disease, significant valvular heart disease, or congenital heart disease, while diabetic cardiomyopathy was defined as DM-related HF without hypertension. Univariable and multivariable logistic regression analyses were performed to identify factors associated with in-hospital mortality. Diabetic cardiomyopathy prevalence was 1.6 % in the entire cohort, 5.2 % in patients with acute HF complicating DM, and 10 % in patients with DM-related HF. Clinical characteristics, including the presence of comorbidities, laboratory data on admission, and factors associated with in-hospital mortality, significantly differed between the diabetic cardiomyopathy group and the DM-related HF with hypertension group. The in-hospital mortality rate was significantly higher in patients with diabetic cardiomyopathy than in patients with DM-related HF with hypertension (7.7 % vs. 2.8 %, respectively; P < 0.001). CONCLUSION: The prevalence of diabetic cardiomyopathy was 1.6 % in patients with acute HF, and patients with diabetic cardiomyopathy were at high risk for in-hospital mortality. The clinical characteristics of patients with diabetic cardiomyopathy were significantly different than those of patients with DM-related HF with hypertension.

AIM: The aim of this study was to clarify the relationship between high or low blood pressure (BP) and cognitive function in elderly outpatients with cardiometabolic diseases. METHODS: We evaluated the association between BP and the Dementia Assessment Sheet for Community-based Integrated Care System-21 items (DASC-21), Mini Mental State Examination (MMSE), and Montreal Cognitive Assessment Tool (MoCA) (N = 677). RESULTS: The patients' mean age was 79.2 ± 6.3 years (male 35.3%), and BP was 132.1 ± 18.1/73.5 ± 12.2 mmHg. Systolic BP (SBP) was linearly related to the DASC-21 score (r = -0.122, P = 0.004), but not to the MMSE score (P = 0.101) or MoCA score (P = 0.802). Multiple linear regression analysis showed that lower SBP was significantly related to the DASC-21 score, even after controlling for confounding factors (B = -0.411 per 10 mmHg; 95% confidence interval [CI], -0.673 to -0.149; P = 0.002). Moreover, logistic regression analysis showed that lower SBP was associated with DASC-21 ≥ 31 (odds ratio = 0.838 per 10 mmHg, P = 0.048). An MMSE score ≤23 was significantly associated with higher SBP in patients without a history of hypertension but with lower SBP in those with hypertension, those on hypertensive medication, and those with dyslipidemia. CONCLUSION: Higher BP was associated with a higher prevalence of probable dementia in those without a history of hypertension, even in late life. In those with hypertension and those taking antihypertensives with comorbidities of stroke or heart failure, lower BP was associated with probable dementia, which was largely dependent on reduced activities of daily living, as measured by the DASC-21 score.

BACKGROUND: Climate is known to influence the incidence of cardiovascular events. However, their prediction with traditional statistical models remains imprecise. METHODS AND RESULTS: We analyzed 27,799 acute heart failure (AHF) admissions within the Tokyo CCU Network Database from January 2014 to December 2019. High-risk AHF (HR-AHF) day was defined as a day with the upper 10th percentile of AHF admission volume. Deep neural network (DNN) and traditional regression models were developed using the admissions in 2014-2018 and tested in 2019. Explanatory variables included 17 meteorological parameters. Shapley additive explanations were used to evaluate their importance. The median number of incidences of AHF was 12 (9-16) per day in 2014-2018 and 11 (9-15) per day in 2019. The predicted AHF admissions correlated well with the observed numbers (DNN: R2â¯=â¯0.413, linear regression: R2â¯=â¯0.387). The DNN model was superior in predicting HR-AHF days compared with the logistic regression model [c-statistics: 0.888 (95% CI: 0.818-0.958) vs 0.827 (95% CI: 0.745-0.910): Pâ¯=â¯.0013]. Notably, the strongest predictive variable was the 7-day moving average of the lowest ambient temperatures. CONCLUSIONS: The DNN model had good prediction ability for incident AHF using climate information. Forecasting AHF admissions could be useful for the effective management of AHF.

OBJECTIVES: Automated office blood pressure (AOBP) measurement often requires assistance. Accompanied by an instructional video, AOBP measurement could be performed independently by patients. DESIGN AND METHODS: Seventy-five patients with hypertension were enrolled. AOBP was measured three times at 1-min intervals after 5â min of rest by an automated BP measurement device with the assistance of an animated instructional video. The video was designed originally to instruct patients on the way to measure BP appropriately. Perceived stress was evaluated using a questionnaire after the AOBP measurement. Office BP was measured three times using the same device. Home BP measurement was performed on 5 consecutive days. RESULTS: The mean age of the patients was 74.5â ±â 10.6 years, and 96% were taking antihypertensive drugs. Mean AOBP, office BP and home BP measurements were 135.2â ±â 17.2/81.3â ±â 11.1, 139.3â ±â 16.3/78.6â ±â 10.9 and 129.2â ±â 16.7/72.7â ±â 8.9â mmHg, respectively. Regarding SBP, the mean AOBP was significantly lower than office BP ( P â =â 0.005) and higher than home BP ( P â =â 0.004). The differences in SBP and DBP between AOBP and home BP measurements were significantly related to patients' perceived stress when performing AOBP measurements ( r â =â 0.289; P â =â 0.013 and r â =â 0.328; P â =â 0.004). In a multivariate analysis, patients' perceived stress was a significant predictor of the difference between AOBP and home BP ( P â =â 0.013), even after adjusting for age, sex, BMI and mean of AOBP and home BP. CONCLUSION: AOBP values measured with the assistance of an instructional video were between conventional office and home BP measurements. Perceived stress during AOBP measurement was related to the difference in AOBP from home BP.

We herein report a 99-year-old woman with hypertension and dyslipidemia. From the beginning of August 20XX, significant edema from the left thigh to the toes had been observed, so she had consulted her previous doctor. She had been suspected of having cellulitis and was given antibiotics, but no improvement in her symptoms was noted, so she was transferred to our hospital. The edema of the lower leg was localized to the left lower leg only, and the D-dimer level was as high as 16.6 µg/mL at her visit to the emergency room, so deep vein thrombosis (DVT) was suspected, and the patient received immediate hospitalization. Continuous administration of undifferentiated heparin was started, and lower extremity venous ultrasound was performed. As a result, central-type DVT extending from the left iliac vein to the common iliac vein bifurcation was observed. However, despite administering inferior vena cava (IVC) filter into under the renal vein, and changing heparin to edoxaban 30 mg, no improvement in the lower limb edema was observed. Therefore, catheter-based thrombolysis (CDT) was started on day 11 of illness, and continuous administration of urokinase was started via the catheter. Heparin and edoxaban were not used in combination in order to reduce the risk of bleeding. The edema gradually improved, and after confirming that the thrombus had completely disappeared on lower extremity venous ultrasound, the catheter was removed on day 14 (day 24 of illness) after starting CDT. The IVC filter was also removed, and prescription of edoxaban 30 mg was restarted. Since the patient had used a walking frame at home, she started rehabilitation from the initiation of CDT therapy and was discharged once she was able to use a self-sustaining portable toilet. The basic treatment for DVT is anticoagulant therapy; however, a large amount of thrombosis was observed in the present case, and no marked improvement was observed with conventional anticoagulant therapy. As the patient was particularly elderly, and considering that it was important to improve the edema promptly in order to maintain her activities of daily living, we performed CDT treatment and concluded that it was very effective in this case. However, the CDT procedure for DVT has yet to be standardized, and there are few cases of CDT treatment, especially for such super-elderly patients. In the current aging society, the incidence of DVT diseases is increasing, and in cases such as the present case, anticoagulation therapy alone and CDT therapy should be considered and implemented after careful consideration of the bleeding risk.

BACKGROUND: Although physical performance tests of the lower extremities are used to assess sarcopenia and frailty, little is known about the mechanisms by which the parameters of ground reaction force (GRF) measured during sit-to-stand motion affect the frailty status in older adults. We aimed to examine the association between GRF parameters during sit-to-stand motion and the incidence of frailty in older adults. METHODS: This longitudinal study evaluated 319 outpatients aged ≥ 65 years with cardiometabolic diseases. The GRF parameters were measured using a motor function analyzer, in which the power, speed, and balance scores were calculated. Frailty was diagnosed using the modified version of the Cardiovascular Health Study (mCHS) and the Kihon Checklist (KCL). The independent associations between scores and frailty indices were assessed using multivariate binomial logistic regression analyses. Cox regression analysis was used to examine whether power and speed scores were associated with the incidence of frailty after adjusting for covariates. RESULTS: Logistic regression analyses adjusted for covariates showed that the power and speed scores were associated with frailty according to the mCHS criteria (power: OR = 0.37, 95% CI = 0.22-0.63; speed: OR = 0.64, 95% CI = 0.52-0.79) and KCL criteria (power: OR = 0.40, 95% CI = 0.26-0.62; speed: OR = 0.81, 95% CI = 0.69-0.96) at baseline. Receiver operating characteristic analyses revealed that the area under the curve values of power and speed scores for discriminating mCHS-defined frailty were 0.72 and 0.73. The Cox regression analysis showed that the speed score predicted the incidence of mCHS-defined (HR = 0.45, 95% CI = 0.22-0.92, P = 0.029) and KCL-defined (HR = 0.77, 95% CI = 0.60-0.99, P = 0.039) frailty, whereas the power score was associated with the incidence of KCL-defined frailty (HR = 0.72, 95% CI = 0.55-0.95, P = 0.02) after adjusting for covariates. CONCLUSIONS: The speed and power scores measured during sit-to-stand motion are predictive of frailty in older adults with cardiometabolic disease. Therefore, the GRF parameters measured during sit-to-stand motion could be an important indicator of frailty. Further studies are necessary to examine whether the GRF parameters can be improved by exercise or whether the changes in these parameters are associated with the improvement of frailty status.

AIM: We aimed to examine the relationship between changes in clinic blood pressure (BP) and frailty and sarcopenia in elderly outpatients with cardiometabolic disease. METHODS: In 691 elderly outpatients with cardiometabolic diseases, the associations of frailty according to the modified Japanese Cardiovascular Health Study score (J-CHS) and Kihon Checklist (KCL) criteria with clinic BP were evaluated at baseline and followed up for 3 years. RESULTS: Among the patients (79.2 ± 6.3 years, male 35.6%), 30.4% had frailty by the J-CHS criteria and 38.0% by the KCL criteria. A J-curve relationship was observed between BP and frailty; the prevalence of frailty was the lowest in patients with systolic BP (SBP) 119.5-130.5 mmHg and in those with diastolic BP (DBP) 72.0-80.5 mmHg. Frailty by the J-CHS criteria correlated with lower DBP (OR = 0.892 per 5 mmHg increase, 95% confidence interval [CI] 0.819-0.972, P = 0.009), whereas that by the KCL criteria correlated with lower SBP (OR = 0.872 per 10 mmHg increase, 95% CI 0.785-0.969, P = 0.011) in multivariate-adjusted models. In patients with frailty by the J-CHS criteria at baseline, changes in DBP (OR = 0.921 per 1 mmHg change, 95% CI 0.851-0.996, P = 0.038) were associated with sustained frailty 1 year later. Changes in DBP were associated with progression to a slow walking speed 1 year later (OR = 0.939, 95% CI 0.883-0.999, P = 0.047). Changes in SBP (OR = 0.928, 95% CI 0.878-0.981, P = 0.008) and DBP (OR = 0.926, 95% CI 0.859-0.997, P = 0.042) were associated with progression to a weak hand grip strength 3 years later. CONCLUSION: A J-curve relationship was observed between frailty and BP, and a decline in BP was associated with progression to a slow walking speed and weak hand grip strength in elderly outpatients with cardiometabolic diseases.

INTRODUCTION: Frailty and depression may play important roles in the management of older patients with cardiometabolic diseases. We explored the determinants of depressive symptoms and their association with frailty among patients with cardiometabolic diseases (hypertension, diabetes, and atrial fibrillation) in a cross-sectional study. METHODS: A total of 633 outpatients aged 65 years or older with cardiometabolic disease and suspected symptoms of frailty participated in this study. Depressive symptoms, physical activity, and social network were assessed using the Geriatric Depression Scale (GDS)-15, International Physical Activity Questionnaire, and Lubben Social Network Scale-6 (LSNS-6), respectively. Frailty was evaluated using the Kihon Checklist (KCL) based on the Comprehensive Geriatric Assessment (CGA), the modified Cardiovascular Health Study (mCHS), and the Clinical Frailty Scale (CFS). Binomial logistic regression analysis was used to examine the determinants of depressive symptoms and their association with frailty. RESULTS: Depressive symptoms with GDS-15 scores ≥ 5 were present in 43.6% of the patients. In logistic regression, after adjusting for covariates, the determinants of depressive symptoms in all patients were lack of social network, low years of education, and frailty. In contrast, in logistic regression with frailty as the dependent variable, depressive symptoms were independently associated KCL-defined frailty (OR = 6.28, 95% CI: 4.13-9.55) and mCHS-defined frailty (OR = 2.66, 95% CI: 1.70-4.17), but not with CFS. Similarly, significant associations between depression and frailty were observed in patients with hypertension, diabetes, or atrial fibrillation. CONCLUSIONS: Lack of social networks, low education, and frailty based on the KCL and mCHS were important determinants of depressive symptoms in all patients. The relatively strong associations between depressive symptoms and frailty based on CGA in patients with hypertension, diabetes, or atrial fibrillation suggest that the assessment of depressive symptoms is of great importance in clinical practice in those patients at high risk of frailty.

BACKGROUND: The impact of the coronavirus disease 2019 (COVID-19) pandemic on the incidence and in-hospital mortality of emergency cardiovascular disease (CVD) has not been clarified in Japan. METHODS: We compared the number of admissions and in-hospital mortality for emergency CVD during the pandemic (from January to December 2020) with those of pre-pandemic periods (from January 2018 to December 2019), using quarterly data from the Tokyo Cardiovascular Care Unit Network. The incidence rate in 2020 is compared with the average incidence rate observed in the same quarter of 2018 and 2019 and is presented as an incidence rate ratio (IRR) with 95â¯% confidence interval (CI). RESULTS: The number of admissions for acute myocardial infarction during the pandemic was significantly lower than before the pandemic, with an IRR of 0.93 (95â¯% CI; 0.88-0.98). Similarly, the IRR for unstable angina was 0.78 (95â¯% CI; 0.72-0.83), for acute heart failure was 0.84 (95â¯% CI; 0.76-0.91), for acute aortic dissection was 0.88 (95â¯% CI; 0.78-0.98), and for ruptured aortic aneurysm was 0.75 (95â¯% CI; 0.62-0.88). In quarterly comparisons, the numbers of acute aortic diseases and emergency arrhythmia significantly decreased from July to September 2020, while those of other emergency CVDs significantly declined in the 2020 April-June period, which includes the first wave period in Japan. In-hospital mortality of emergency CVDs was unchanged from the pre-pandemic period, except for acute aortic dissection, which increased in odds ratio of 1.31 (95â¯% CI 1.10-1.57). CONCLUSIONS: The COVID-19 pandemic significantly reduced the number of admissions for all emergency CVDs in all or part of the year. In-hospital mortality was unchanged from the pre-pandemic period, except for acute aortic dissection, which increased.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a standard treatment for elderly and high-risk patients with aortic valve stenosis (AS); however, its short-term effects on blood pressure (BP) and cardiac function are not clear. Therefore, we aimed to determine the short-term effects of TAVR in elderly patients (>75 years), who reflect the clinical situation in Japan. METHOD AND RESULTS: Twenty-eight consecutive elderly patients with severe AS and hypertension who underwent TAVR under general anesthesia were retrospectively investigated. All patients had hypertension that was well controlled with antihypertensive drugs. Serum brain natriuretic peptide level and peak velocity in the aortic valve were significantly reduced. TAVR induces an increase in BP that requires additional antihypertensive agents. There was no correlation between the change rate of SBP and stroke volume index (SVI), but there was a positive correlation between the rate of change in pulse pressure (PP) and SVI. This tendency was particularly observed in patients with low brachial-ankle pulse wave velocity (baPWV). CONCLUSION: We observed post-TAVR hypertension and required additional antihypertensive drugs. The increases in SVI and PP after TAVR resulted in post-TAVR hypertension. Moreover, post-TAVR hypertension is less likely to occur in elderly patients with a high baPWV, which indicates advanced arteriosclerosis.

An 80-year-old woman with a history of hypertrophic obstructive cardiomyopathy and Lewy body dementia was admitted to our hospital with a first episode of syncope while walking. The pressure gradient of left ventricular outflow tract (LVOT) had been stable at nearly 10 mmHg for 3 years before the admission. We evaluated the cause of syncope. Echocardiography showed that the pressure gradient of LVOT was unchanged, even in the supine position ergometer exercise test. Although the head-up tilt test revealed a drop in blood pressure of 44 mmHg systolic and 23 mmHg diastolic, she was asymptomatic during the test. The orthostatic hypotension was considered to be a manifestation of autonomic failure due to Lewy body dementia; however, it was insufficient to explain the syncope on exertion. Echocardiography in a sitting-up position showed that the pressure gradient of LVOT was exacerbated to 41 mmHg, which might be the cause of syncope while walking. Orthostatic hypotension, especially in patients with Lewy body dementia, is a common cause of syncope in the elderly. However, we should keep in mind that the exacerbation of LVOT obstruction due to posture-dependent fluid shift can be a cause of syncope in patients with hypertrophic cardiomyopathy or sigmoid-shaped interventricular septum. In such patients, echocardiography in a sitting-up position can be an effective tool to diagnose the cause of syncope.

Evidence suggests that older people aged ≥65 years and those aged 60-64 years with chronic medical conditions are at higher risk of developing severe complications due to influenza virus infection when compared with young, healthy adults. Although seasonal influenza is monitored through a nationwide passive surveillance in Japan, influenza related outcomes and medical resource consumption have not been fully documented. This retrospective database study aimed to describe the epidemiological and clinical characteristics of medically attended influenza cases aged ≥60 years and the associated medical resource consumption in Japan. We used clinically diagnosed influenza (CDI) based on the international classification of disease codes, and laboratory-confirmed influenza (LCI) based on influenza test results, to identify the patient population during a total of nine seasons (2010/2011 to 2018/2019). A total of 372,356 CDI and 31,122 LCI cases were identified from 77 medical institutions. The highest numbers of medically-attended influenza episodes were in patients aged 65-74 years and 75-84 years. On average, across seasons, 5.9% of all-cause hospitalizations were attributable to CDI and 0.4% were LCI. Influenza viruses type A and B co-circulated annually in varying degree of intensity and were associated with similar level of complications, including cardiovascular-related. Oxygen therapy increased with age; by contrast, mechanical ventilation, dialysis, blood transfusion, and intensive care unit admission were higher in the younger groups. In-hospital mortality for inpatients aged ≥ 85 years with CDI and LCI were 18.6% and 15.5%, respectively. Considering the burden associated with medically-attended influenza in this population, influenza prevention, laboratory confirmation and clinical management should be emphasized by general practicians and specialists like cardiologists to protect this aging population.

AIMS: Evidence on the association between ambient temperature and the onset of acute heart failure (AHF) is scarce and mixed. We sought to investigate the incidence of AHF admissions based on ambient temperature change, with particular interest in detecting the difference between AHF with preserved (HFpEF), mildly reduced (HFmrEF), and reduced ejection fraction (HFrEF). METHODS AND RESULTS: Individualized AHF admission data from January 2015 to December 2016 were obtained from a multicentre registry (Tokyo CCU Network Database). The primary event was the daily number of admissions. A linear regression model, using the lowest ambient temperature as the explanatory variable, was selected for the best-estimate model. We also applied the cubic spline model using five knots according to the percentiles of the distribution of the lowest ambient temperature. We divided the entire population into HFpEF + HFmrEF and HFrEF for comparison. In addition, the in-hospital treatment and mortality rates were obtained according to the interquartile ranges (IQRs) of the lowest ambient temperature (IQR1 <5.5°C; IQR25.5-13.3°C; IQR3 13.3-19.7°C; and IQR4 >19.7°C). The number of admissions for HFpEF, HFmrEF and HFrEF were 2736 (36%), 1539 (20%), and 3354 (44%), respectively. The lowest ambient temperature on the admission day was inversely correlated with the admission frequency for both HFpEF + HFmrEF and HFrEF patients, with a stronger correlation in patients with HFpEF + HFmrEF (R2 = 0.25 vs. 0.05, P < 0.001). In the sensitivity analysis, the decrease in the ambient temperature was associated with the greatest incremental increases in HFpEF, followed by HFmrEF and HFrEF patients (3.5% vs. 2.8% vs. 1.5% per -1°C, P < 0.001), with marked increase in admissions of hypertensive patients (systolic blood pressure >140 mmHg vs. 140-100 mmHg vs. <100 mmHg, 3.0% vs. 2.0% vs. 0.8% per -1°C, P for interaction <0.001). A mediator analysis indicated the presence of the mediator effect of systolic blood pressure. The in-hospital mortality rate (7.5%) did not significantly change according to ambient temperature (P = 0.62). CONCLUSIONS: Lower ambient temperature was associated with higher frequency of AHF admissions, and the effect was more pronounced in HFpEF and HFmrEF patients than in those with HFrEF.

Minor ST-T changes on electrocardiograms are observed in patients with hypertensive heart disease with a preserved left ventricular ejection fraction (LVEF); however, the relationship between minor ST-T changes and global myocardial work on echocardiograms remains unclear. We evaluated the global longitudinal strain (GLS), global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE) in 186 hypertensive patients with preserved LVEF (>50%) using an offline analysis system (View Pal, GE). Minor ST-T changes as well as major ST-T changes (depression in ST in lead V5 > 1 mV) were also evaluated by electrocardiography. The mean age was 79.4 ± 8.2 years (men 37.6%). Patients with minor and major ST-changes had a smaller absolute GLS (-20.3 ± 3.1, -18.2 ± 3.7, and -15.2 ± 5.0%, P < 0.001) and a smaller constructive workload [GWI (2148 ± 486, 1938 ± 462, and 1685 ± 701 mmHg%, P = 0.002) and GCW (2419 ± 510, 2185 ± 466, and 1865 ± 702 mmHg%, P < 0.001)] than those with no ST-T changes. Additionally, patients with minor and major ST-T changes had increased wasted myocardial work [GWW (87 ± 61, 105 ± 56, and 127 ± 75 mmHg%, P = 0.045)], which resulted in reductions in the myocardial work efficiency [GWE (95 ± 4, 94 ± 3, and 89 ± 12%, P < 0.001)]. Even after adjustments for confounding factors, including EF, diastolic function parameters, LV hypertrophy, history of heart failure and atrial fibrillation, patients with minor ST-T changes had significantly smaller LV global constructive work in comparison to those without [GWI (2260 ± 33 vs. 2025 ± 76 mmHg%, P = 0.007) and GCW (2501 ± 45 vs. 2210 ± 105 mmHg%, P = 0.003)]. In conclusion, in hypertensive patients with preserved LVEF, minor ST-T changes on electrocardiograms were associated with reduced constructive work in the LV.

Myocardial ischemia due to narrowing of the right coronary artery (RCA) may result in sinus arrhythmias, which usually present as transient sinus bradycardia with no hemodynamic instability. We report a rare case of sinus arrest with hemodynamic instability, which lasted for several months, and was caused by the occlusion of the sinus node (SN) artery following the RCA stenting. A 78-year-old woman with diabetes mellitus, hypertension, and dyslipidemia was referred to our hospital because of chest pain during activity. In her coronary angiogram, severe diffuse stenosis of the RCA was observed and intracoronary imaging using intravascular ultrasound revealed diffuse atherosclerotic plaque lesions with partial calcification and vulnerability. RCA was treated by inserting three zotarolimus-eluting stents. Immediately after these interventions, the SN artery originating from the RCA proximal to the lesion was occluded, which resulted in SN dysfunction. Significant bradycardia was observed on electrocardiogram along with low blood pressure, suggesting sinus arrest. Along with hemodynamic instability, sinus arrest lasted for several months, and permanent pacemaker implantation was needed. The plaque burden should be taken into consideration when choosing the appropriate percutaneous coronary intervention strategy because of the potential complication of sinus arrest after RCA stenting.
RESUMEN
PURPOSE: An increased blood pressure variability (BPV) has been reported to be associated with older age and cognitive dysfunction; however, associations between increased BPV and rapid eye movement sleep behaviour disorder (RBD) has not been thoroughly investigated in patients without clinical Lewy body diseases. MATERIALS AND METHODS: In frailty outpatient clinic, we evaluated ambulatory BP, RBD screening questionnaire (RBDSQ), and beat-to-beat heart rate variability during positional change from sitting to standing in 112 elderly hypertensive patients. RESULTS: The mean age was 81.2 ± 6.3 years (68% male). There were 15 patients who had probable RBD (RBDSQ scores ≥ 5). Patients with RBD had a greater body mass index, coefficient of variation (CV) in 24-h diastolic BP (23.5 ± 6.1 versus 18.7 ± 5.8, p = 0.005), awake diastolic BP (23.0 ± 7.7 versus 18.6 ± 6.2, p = 0.017), and nocturnal systolic BP (14.9 ± 5.5 versus 12.0 ± 4.4, p = 0.025) compared with those without RBD, while systolic BP, diastolic BP, and cognitive function did not differ significantly between patients with and without RBD. Patients with RBD exhibited larger orthostatic BP fall compared with patients without RBD (-4.9 ± 11.0 versus 7.5 ± 11.8, p = 0.009) and lower CV of R-R intervals while standing (1.3 ± 0.6 versus 2.4 ± 1.5, p = 0.039). Multiple regression analysis revealed that patients with RBD had significantly greater CV of nocturnal systolic BP independent of age, sex, BMI, history of diabetes and dyslipidaemia, and use of antihypertensive drugs (p = 0.008). CONCLUSION: An increased BPV in ambulatory BP, associated with autonomic dysfunction, can be observed in patients with probable RBD even in elderly patients without clinical presentation of Lewy body diseases.
