Blood pressure response during exercise testing in individuals with and without hypertension: The value of the recovery phase. Eur J Clin Invest 2024:e14285. [PMID: 38994816 DOI: 10.1111/eci.14285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 06/28/2024] [Indexed: 07/13/2024]
Abstract
BACKGROUND Hypertension and exercise testing are essential for cardiovascular risk assessment. However, an exact description of blood pressure (BP) in patients with a hypertensive response during exercise (HRE), especially in the recovery phase is lacking. Herein, we aimed to analyse BP and heart rate during exercise testing and recovery in patients with an HRE. METHODS 800 patients aged 17-90 with an HRE during a standardized bicycle ergometry test were recruited. The BP behaviour during exercise testing was correlated with clinical data. Furthermore, data were analysed according to the presence of pre-existent hypertension. RESULTS Of the 800 patients included in this study 497 (62%) were previously diagnosed with hypertension. Analysis of covariance showed a significantly faster systolic (β [95% CI] 8.0 [4.9-11.1]) and diastolic (2.4 [0.4-4.4]) BP recovery 3 min after maximal exercise in patients without hypertension in univariable models. These results remained robust in fully adjusted models taking into account age, sex, body mass index, cardiovascular disease, and antihypertensive treatment for systolic (5.3 [1.2-9.4]) and diastolic BP (4.5 [1.9-7.0]). Furthermore, patients with hypertension displayed higher systolic BP during maximal exercise in univariable (3.8 [0.1-7.5]) and fully adjusted (5.5 [1.1-10.0]) models. There was no difference in maximum diastolic BP between groups. CONCLUSION In this large cohort study, patients without hypertension showed a faster systolic and diastolic BP recovery and lower maximal systolic BP compared to patients with hypertension. Overall, this study provides new insights into cardiovascular health during recovery phase.

[PMID: 38108241 PMCID: PMC10863753 DOI: 10.1161/jaha.123.031627] [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: 07/05/2023] [Accepted: 11/20/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Both nighttime systolic blood pressure and pulse rate are associated with adverse outcomes in patients with chronic kidney disease (CKD). However, nighttime double product (DP), which is the product of nighttime systolic blood pressure and pulse rate, has not yet been investigated in this context. The present study aimed to explore the prognostic value of nighttime DP for adverse outcomes in patients with CKD and hypertension. METHODS AND RESULTS This retrospective cohort study included a total of 1434 patients with nondialysis CKD complicated by hypertension. The patients were enrolled in Zhuhai and Guangzhou, China, with a median follow-up of 23.8 months. Patient enrollment for the high or low nighttime DP group was performed on the basis of the cutoff value determined by time-dependent receiver operator characteristic curve analysis. The primary end point was a composite of major cardiovascular and cerebrovascular events, and the secondary end point was all-cause death and composite renal end point. The 24-hour circadian DP rhythm was established via multiple-component cosinor analysis. Cox regression was used to explore the association between nighttime DP and adverse outcomes. The DP of nondialysis patients with CKD and hypertension showed a diurnal rhythm, which varied with renal function. After adjustment, high nighttime DP was associated with a higher risk for major cardiovascular and cerebrovascular events (hazard ratio [HR], 5.823 [95% CI, 2.382-14.233]), all-cause death (HR, 4.978 [95% CI, 2.205-11.240]), and composite renal event (HR, 1.661 [95% CI, 1.128-2.447]), compared with low nighttime DP. These associations were independent of nighttime systolic blood pressure and PR. CONCLUSIONS The present cohort study demonstrated that DP had diurnal fluctuations and nighttime DP was an important prognostic factor in nondialysis patients with CKD and hypertension, outperforming traditional risk factors, including systolic blood pressure and pulse rate.

[PMID: 37944305 DOI: 10.1016/j.clineuro.2023.107992] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 07/04/2023] [Accepted: 09/26/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVE To evaluate the risk factors for acute cerebral infarction(ACI) in patients with non-variceal upper gastrointestinal bleeding(NVUGIB), and construct a model for predicting ACI in NVUGIB patients. METHODS A model for predicting ACI induced by NVUGIB was established on the basis of a retrospective study that involved 1282 patients who were diagnosed with NVUGIB in the emergency department and Gastroenterology Department of Nanchang University Affiliated Ganzhou Hospital from January 2019 to December 2021. Receiver operating characteristic (ROC) curves were drawn to evaluate the sensitivity and specificity of the model and CHA2DS2-VASc score to predict ACI. Delong's test was used to compare AUCs of the present score and the CHA2DS2-VASc score. RESULTS There were 1282 patients enrolled in the study, including 69 in the ACI group and 1213 in the non-ACI group. Multivariate analysis revealed that hypertension, diabetes, red blood cell (RBC) transfusion, mechanical ventilation, D-dimer, rate pressure product (RPP), somatostatin and mean platelet volume (MPV) were factors associated with ACI induced by NVUGIB. A model based on the eight factors was established, Logit(P)= 0.265 + 1.382 × 1 + 1.120 × 2 + 1.769 × 3 + 0.839 × 4-1.549 × 5-0.361 × 6 + 0.045 × 7 + 1.158 × 8(or 1.069 ×9) (X1, hypertension=1; X2, diabetes=1; X3, RBC transfusion=1; X4, mechanical ventilation=1; X5, somatostatin=1; X6, MPV(fL); X7, D-dimer(ng/l); X8, low RPP= 1; X9, high RPP = 2). The area under ROC curve of the model was 0.873, the sensitivity and specificity were 0.768 and 0.887, respectively. The area under ROC curve of CHA2DS2-VASc score was 0.792, the sensitivity and specificity were 0.728 and 0.716, respectively. Delong's test showed the area under ROC curve of the present study was significantly larger than that of CHA2DS2-VASc score. CONCLUSIONS Hypertension, diabetes, RBC transfusion, mechanical ventilation, D-dimer, RPP, somatostatin and MPV were factors associated with ACI induced by NVUGIB. A model constructed based on these factors showed excellent prediction of ACI, and was superior to CHA2DS2-VASc score. However, this needs to be further validated by multi-center study with a larger sample size.

Abstract
OBJECTIVE This study aimed to analyze the correlation between the rate pressure product (RPP) and cardiopulmonary function during hospitalization in patients with acute myocardial infarction (AMI). METHODS A total of 362 patients with AMI were selected for the study, and the median admission RPP was used as the cutoff point to divide the patients into a low-RPP group (n = 181) and a high-RPP group (n = 181). The relationship between the RPP at admission and the cardiopulmonary function during hospitalization was analyzed. RESULTS The patients in the high-RPP group had a higher body mass index (BMI) (p = 0.014), a higher prevalence of combined hypertension and diabetes mellitus (p < 0.001), a lower incidence of smoking (p = 0.044), and a higher incidence of oscillatory ventilation (6.1% vs. 1.7%, p = 0.029). The differences in RPP at rest, during warm-up, and within 1 and 4 minutes of recovery were statistically significant between the two groups (p < 0.01 on each occasion), while the differences in anaerobic threshold (AT) and watt max (Max) were not statistically significant (p > 0.05 for both). The patients in the low-RPP group had higher oxygen uptake (VO2 [AT]: 14.9 ± 3.4 vs. 14.2 ± 3.6, p = 0.048) and (VO2peak [Max]:18.2 ± 3.8 vs. 17.3 ± 3.8, p = 0.020). The RPP at admission was negatively correlated with VO2 (AT) and VO2peak (p < 0.05) using the regression Equation VO2peak = 33.682 + (-0.012 * RPP at admission/100) + (-0.105 * Age) + (-0.350 * BMI), while there was no correlation between the RPP at admission and VO2 (AT) (p = 0.149). CONCLUSION The RPP at admission was negatively correlated with cardiopulmonary function during hospitalization in patients with AMI. Patients with a high RPP were more likely to have a combination of obesity, hypertension, diabetes mellitus, and reduced oxygen uptake during exercise, while a high RPP at admission appeared to affect their cardiovascular response indicators during exercise.

Abstract
Compared to preterm appropriate for gestational age (AGA) fetuses, fetuses with fetal growth restriction (FGR) have earlier visualisation of coronary artery blood flow (CABF) but impaired cardiac function. This dichotomy remains uncharacterised during postnatal life. This study compared CABF and cardiac function in preterm FGR infants, against AGA infants during the postnatal period. FGR was defined as birthweight < 10th centile for gestation and sex with absent/reversed antenatal umbilical artery Doppler. Diastolic CABF was measured in the left anterior descending coronary artery. Twenty-eight FGR infants were compared with 26 AGA infants (gestation and birthweight, 29.7 ± 1.3 vs 29.9 ± 1 weeks, P = 0.6 and 918 ± 174 vs 1398 ± 263g, P < 0.001, respectively). Echocardiography was performed in the second week of life. FGR infants had higher CABF (velocity time integral, 2.4 ± 0.9 vs 1.6 ± 0.8 cm, P = 0.002). Diastolic function was impaired (↑ trans-mitral E/A ratio in FGR infants; 0.84 ± 0.05 vs 0.79 ± 0.03, P = 0.0002) while the systolic function was also affected (mean velocity of circumferential fibre shortening [mVCFc], 1.9 ± 0.3 vs 2.7 ± 0.5 circ/s, P < 0.001). Indexing CABF to cardiac function noted significant differences between the groups (CABF: E/A [FGR vs AGA], 2.9 ± 1.1 vs 2.1 ± 1, P = 0.01 and CABF: mVCFc [FGR vs AGA], 1.3 ± 0.5 vs 0.6 ± 0.3, P < 0.001). Diastolic blood pressure (BP) was significantly higher, and CABF to diastolic BP ratio trended higher in FGR infants (30 ± 2 vs 25 ± 3 mmHg, P < 0.001 and 0.08 ± 0.03 vs 0.06 ± 0.03, P = 0.059, respectively). Greater CABF in FGR infants did not translate into better cardiac function. This dichotomy may be a persistent response to fetal hypoxaemia (fetal programming) and/or reflection of altered cardiac architecture.

Abstract
The joint effect of blood pressure (BP) and heart rate (HR) on cardiovascular disease is unclear. Rate pressure product (RPP), the product of systolic BP and HR, is assessed in this study. This study aimed to determine the longitudinal patterns of RPP from childhood to adulthood and to explore the relationship between RPP trajectories in early life and left ventricular hypertrophy (LVH) in midlife. We included individuals with 3 or more RPP values from 7 visits over a 30-year follow-up period in the Hanzhong Adolescent Hypertension Study cohort to fit trajectory groups and performed logistic regression to evaluate the relative risk of developing LVH. Three discrete trajectories in RPP were identified among 2412 participants assessed from childhood to middle-aged adulthood, which were tagged as "low stable," "moderate stable," and "moderate increasing". A higher waist-to-hip ratio, smoking, alcohol consumption, hypertension, diabetes, and hyperlipidemia were associated with increased RPP trajectories. The Cornell voltage product was positively correlated with RPP in 2017 and was higher in the moderate-stable and moderate-increasing groups than in the low-stable group in RPP trajectories. Compared with the low-stable group, the ORs of LVH were 1.65 (1.13, 2.92) for the moderate-stable and 3.56 (2.26, 5.44) for the moderate-increasing group. Subjects with moderate-stable and moderate-increasing trajectories showed higher probabilities of LVH at an elderly age than those in the low stable trajectory group even after adjusting for multiple cardiovascular risk factors. RPP trajectories are identifiable from childhood and are associated with LVH in midlife. Monitoring RPP trajectories from early life may be an effective approach to predict cardiovascular health status later in life.

Abstract
OBJECTIVE Weight stigma induces cardiovascular health consequences for people with obesity. How stigma affects cardiovascular reactivity in individuals with both obesity and hypertension is not known. METHODS In a randomized experiment, we assessed the influence of two video exposures, depicting either weight stigmatizing (STIGMA) or non-stigmatizing (NEUTRAL) scenes, on cardiovascular reactivity [resting blood pressure (BP), heart rate (HR), ambulatory BP (ABP), and ambulatory HR (AHR)], among women with obesity and high BP (HBP; n=24) or normal BP (NBP; n=25). Systolic ABP reactivity was the primary outcome. Laboratory BP and HR were measured before/during/following the videos, and ABP and AHR were measured over 19 hours (10 awake hours, 9 sleep hours) upon leaving the laboratory. A repeated measures ANCOVA tested differences in BP and HR changes from baseline in the laboratory and over ambulatory conditions between the two groups after each video, controlling for body mass index, baseline BP and HR. RESULTS Laboratory SBP/DBP increased 5.5+7.3/2.4+8.8mmHg more in women with HBP than NBP following the STIGMA versus NEUTRAL video (Ps<0.05). For the primary outcome, ABP increased more in HBP than NBP over sleep (SBP/DBP=4.2+20.6/4.7+14.2mmHg; Ps<0.05) following the STIGMA versus NEUTRAL video, as did HR during sleep (7.5+15.7bpm more in HBP than NBP; P<0.05). CONCLUSIONS Weight stigma increases cardiovascular reactivity among women with obesity and HBP in the laboratory and under ambulatory conditions.

Admission rate-pressure product as an early predictor for in-hospital mortality after aneurysmal subarachnoid hemorrhage. Neurosurg Rev 2022; 45:2811-2822. [PMID: 35488072 DOI: 10.1007/s10143-022-01795-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 03/18/2022] [Accepted: 04/19/2022] [Indexed: 10/18/2022]
Abstract
Early prediction of in-hospital mortality in aneurysmal subarachnoid hemorrhage (aSAH) is essential for the optimal management of these patients. Recently, a retrospective cohort observation has reported that the rate-pressure product (RPP, the product of systolic blood pressure and heart rate), an objective and easily calculated bedside index of cardiac hemodynamics, was predictively associated with in-hospital mortality following traumatic brain injury. We thus wondered whether this finding could also be generalized to aSAH patients. The current study aimed to examine the association of RPP at the time of emergency room (ER) admission with in-hospital mortality and its predictive performance among aSAH patients. We retrospectively included 515 aSAH patients who had been admitted to our ER between 2016 and 2020. Their baseline heart rate and systolic blood pressure at ER presentation were extracted for the calculation of the admission RPP. Meanwhile, we collected relevant clinical, laboratory, and neuroimaging data. Then, these data including the admission RPP were examined by univariate and multivariate analyses to identify independent predictors of hospital mortality. Eventually, continuous and ordinal variables were selected from those independent predictors, and the performance of these selected predictors was further evaluated and compared based on receiver operating characteristic (ROC) curve analyzes. We identified both low (< 10,000; adjusted odds ratio (OR) 3.49, 95% CI 1.93-6.29, p < 0.001) and high (> 15,000; adjusted OR 8.42, 95% CI 4.16-17.06, p < 0.001) RPP on ER admission to be independently associated with in-hospital mortality after aSAH. Furthermore, after centering the admission RPP by its median, the area under its ROC curve (0.761, 95% CI 0.722-0.798, p < 0.001) was found to be statistically superior to any of the other independent predictors included in the ROC analyzes (all p < 0.01). In light of the predictive superiority of the admission RPP, as well as its objectivity and easy accessibility, it is indeed a potentially more applicable predictor for in-hospital death in aSAH patients.

Abstract
AbstractSeveral tests are available for assessing cardiovascular response to various interventions which may be given in the laboratory, or outside of it in the field. The tests are meant to excite or deactivate cardiovascular and other sensory receptors which signal the central mechanisms. They have been found useful in generating data to study cardiovascular effects on subjects exposed to specialized physical training (e.g., athletes), in the evaluation of people engaged in special occupations such as pilots, astronauts, and other military personnel, and in training undergraduate and postgraduate students. If the response does not fit into the physiological norm, it may reflect a temporary aberration, or a more serious defect in the cardiovascular control mechanism because of disease. Interpretation of data generated may vary between various operators/observers. Here, an attempt has been made to bring out responses of the cardiovascular system to the commonly used tests, and their applicability in clinical situations.

[PMID: 35433537 PMCID: PMC9005773 DOI: 10.3389/fped.2022.802469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Accepted: 02/03/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND To investigate the predictive value of heart rate (HR) and blood pressure (BP) on the prognosis of postural tachycardia syndrome (POTS) in children. MATERIALS AND METHODS 53 cases of children aged 5 to 15 years who visited in the Pediatric Syncope Specialist Clinic of The Second Xiangya Hospital of Central South University for unexplained syncope or syncope precursor were diagnosed with POTS by head-up tilt test (HUTT) as the POTS group. 38 healthy children aged 5 to 16 years who underwent physical examination at the Child Health Care Clinic of the hospital in the same period were matched as controls (control group). The children with POTS were followed up after 3 months of treatment and were divided into good prognosis group (40 cases) and poor prognosis group (13 cases) according to the results of HUTT re-examination and whether the symptoms improved or not. HR and BP indicators were collected from each group at baseline and during HUTT. RESULTS There were 91 research subjects, of which 45 are males, with a mean age of 11.52 ± 2.13 years. (1) HR at 5 and 10 min (HR 5 and HR 10, respectively), HR difference at 5 and 10 min (HRD 5 and HRD 10, respectively), and HR and BP product at 5 and 10 min (RPP 5 and RPP 10, respectively) were greater in the POTS group than in the control group (P < 0.01). (2) HR 5, HR 10, HRD 5, HRD 10, and RPP 10 in children with POTS were smaller in the good prognosis group than the poor prognosis group (P < 0.01). (3) The area under curve was 0.925 on the four combined indicators (HR 5, HR 10, HRD 5, and HRD 10), predicting a good prognosis of POTS, sensitivity of 99.99%, and specificity of 75.00%. CONCLUSIONS HR 5, HR 10, HRD 5, HRD 10, and RPP 10 and the four combined indicators (HR 5, HR 10, HRD 5, and HRD 10) had predictive value for the POTS prognosis in children. The predictive value of the four combined indicators for the POTS prognosis was better than that of the single HR 5, HRD 5, and RPP 10.

Effects of dapagliflozin and gliclazide on the cardiorenal axis in people with type 2 diabetes. J Hypertens 2021; 38:1811-1819.

Abstract
OBJECTIVES There is a bidirectional relationship between cardiovascular and renal disease. The drug-class of SGLT2 inhibitors improves outcomes at both ends of this so called cardiorenal axis. We assessed the effects of SGLT2 inhibition and sulfonylurea treatment on systemic hemodynamic function and investigated whether SGLT2 inhibitor-induced changes in systemic hemodynamics correlate with changes in renal hemodynamics. METHODS Forty-four people with type 2 diabetes were randomized to 12 weeks of dapagliflozin 10 mg/day or gliclazide 30 mg/day treatment. Systemic hemodynamic function, autonomic nervous system activity, and vascular stiffness were measured noninvasively, whereas renal hemodynamics, glomerular filtration rate (GFR) and effective renal plasma flow, were assessed with gold-standard urinary clearances of inulin or iohexol and para-aminohippuric acid, respectively. Correlation analyses were performed to assess relationships between dapagliflozin-induced changes in cardiovascular and renal variables. RESULTS Dapagliflozin reduced stroke volume by 4%, cardiac output by 5%, vascular stiffness by 11%, and mean arterial pressure by 5% from baseline, without increasing heart rate or sympathetic activity, while simultaneously lowering glomerular filtration rate by 8%. Despite similar improvements in glycemic control by dapagliflozin and gliclazide (-0.5 ± 0.5 versus-0.7 ± 0.5%; P = 0.12), gliclazide did not affect any of these measurements. There was no clear association between the dapagliflozin-induced changes in cardiovascular and renal physiology. CONCLUSION Dapagliflozin seemingly influences systemic and renal hemodynamics independently and beyond glucose lowering in people with type 2 diabetes.This clinical trial was registered at https://clinicalTrials.gov (ID: NCT02682563).

Abstract
There is a growing need for remote monitoring of patients due to a lack of resources and infection control. Current systems use sensors that require constant physical contact with the user, which may result in discomfort or lack of adherence. In the present study, we evaluated the accuracy of a new contact-free system to monitor heart and respiratory rate. Study participants were measured simultaneously using two devices: a contact-free optical system that measures nano-vibrations and movements (investigational device, "Gili Pro BioSensor") and a standard reference bed-side monitor, inclusive of an electrocardiogram and capnograph modules (Mindray®). Co-primary endpoints included HR and RR accuracy in subjects without active arrhythmias for HR, and for all study populations for RR (i.e., for subjects with and without active arrhythmias). Confirmatory secondary endpoints included HR scored continuously for all study populations, inclusive of subjects with arrhythmias. The present study included 115 patients who completed study procedures. Mean age was 66 ± 14.6 (range 29-93) with 60% males, 31% obese patients (i.e., BMI > 30 kg/m2, range 17-44) and 56% measured in a chair. For the dichotomised accuracy analysis, both co-primary endpoint for HR and RR resulted in 100% accuracy (95% CI: HR 98.8-100%; RR 98.9-100%), whereas for the confirmatory secondary analysis, 99.1% of the HR measurements across subjects with and without active arrhythmias were deemed accurate (95% CI: 97.4-99.8%). The current study demonstrated over 99% accuracy in detecting heart and respiratory rate using a novel contact-free optical system.

Abstract
OBJECTIVES To determine the correlation between anthropometric indices and the selected hemodynamic parameters among secondary adolescents aged 12-17 years. RESULTS Our findings showed weak positive correlation between generally body surface area, neck circumference and conicity index with the hemodynamic parameters (systolic blood pressure, diastolic blood pressure, resting pulse rate, mean arterial pressure, rate pressure product and pulse pressure). However, the ponderosity index, body mass index and waist hip ratio showed negative weak correlations with the hemodynamic parameters. There was a significant difference in pulse pressure among the BMI categories. All parameters showed significant (p < 0.05) differences across the categories of neck circumference and waist hip ratio. Generally, in multivariate regression analysis, anthropometric indices showed significant prediction of the hemodynamic parameters.

Abstract
OBJECTIVES To determine whether shock index, coronary perfusion pressure, or rate pressure product in the first 24 hours after congenital heart surgery are independent predictors of subsequent clinically significant adverse outcomes. DESIGN A retrospective cohort study. SETTING A tertiary care center. PATIENTS All patients less than 18 years old who underwent cardiac surgery at Boston Children's Hospital between January 1, 2010, and December 31, 2018. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Shock index (heart rate/systolic blood pressure), coronary perfusion pressure (diastolic blood pressure-right atrial pressure), and rate pressure product (heart rate × systolic blood pressure) were calculated every 5 seconds, and the median value for the first 24 hours of cardiac ICU admission for each was used as a predictor. The composite, primary outcome was the occurrence of any of the following adverse events in the first 7 days following cardiac ICU admission: cardiopulmonary resuscitation, extracorporeal cardiopulmonary resuscitation, mechanical circulatory support, unplanned surgery, heart transplant, or death. The association of each variable of interest with this outcome was tested in a multivariate logistic regression model. Of the 4,161 patients included, 296 (7%) met the outcome within the specified timeframe. In a multivariate regression model adjusted for age, surgical complexity, inotropic and respiratory support, and organ dysfunction, shock index greater than 1.83 was significantly associated with the primary outcome (odds ratio, 6.6; 95% CI, 4.4-10.0), and coronary perfusion pressure greater than 35 mm Hg was protective against the outcome (odds ratio, 0.5; 0.4-0.7). Rate pressure product was not found to be associated with the outcome. However, the predictive ability of the shock index and coronary perfusion pressure models were not superior to their component hemodynamic variables alone. CONCLUSIONS Both shock index and coronary perfusion pressure may offer predictive value for adverse outcomes following cardiac surgery in children, although they are not superior to the primary hemodynamic variables.

Abstract
Systolic (SBP) and diastolic blood pressure (DBP) and mean arterial pressure (MAP) are risk factors for cardiovascular mortality (CVM). Pulse pressure (PP) is considered as an easily available marker of vascular stiffness and the double product (DP) as a marker of cardiac workload. Therefore, we have examined the predictive value of PP and DP in the Ludwigshafen Risk and Cardiovascular Health study, a monocentric cohort study of 3316 patients referred to coronary angiography. An increase of SBP or PP by 1mmHg increased the risk of CVM with hazard ratios of 1.009 (95% CI, 1.005-1.012) and 1.016 (1.012-1.020), respectively. Increasing DP by 100 mm Hg/min was associated with a 1.010 (1.007-1.013) higher risk of CVM. In patient subgroups with coronary artery disease (CAD) and heart failure (HF), PP and DP predicted CVM better than SBP or MAP. In a multivariate analysis adjusted for sex, BMI, diabetes, eGFR, hazard ratios for CVM for z-standardized PP, DP, SBP, and HR were 1.20, 1.16, 1.12, and 1.14. After adding age to the multivariate analysis, only DP and HR remained significant. We provide evidence that PP and DP are powerful predictors of CVM and all-cause mortality in a CV medium- to high-risk population, especially in patients with CAD and HF. While DP proved to be an independent predictor of cardiovascular and all-cause mortality also in multivariate analysis, PP was no independent predictor in our cohort with widespread antihypertensive treatment (>85%). PP is associated with age, presence of diabetes, obesity, and impaired renal function.

Rate pressure product and the components of heart rate and systolic blood pressure in hospitalized heart failure patients with preserved ejection fraction: Insights from ASCEND-HF. Clin Cardiol 2018; 41:945-952. [PMID: 29781109 DOI: 10.1002/clc.22981] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2018] [Revised: 05/14/2018] [Accepted: 05/16/2018] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Heart rate and systolic blood pressure (SBP) are prognostic markers in heart failure (HF) with reduced ejection fraction (HFrEF). Their combination in rate pressure product (RPP) as well as their role in heart failure with preserved ejection fraction (HFpEF) remains unclear. HYPOTHESIS RPP and its components are associated with HFpEF outcomes. METHODS We performed an analysis of Acute Study of Clinical Effectiveness of Nesiritide in Subjects With Decompensated Heart Failure (ASCEND-HF; http://www.clinicaltrials.gov NCT00475852), which studied 7141 patients with acute HF. HFpEF was defined as left ventricular ejection fraction ≥40%. Outcomes were assessed by baseline heart rate, SBP, and RPP, as well as the change of these variables using adjusted Cox models. RESULTS After multivariable adjustment, in-hospital change but not baseline heart rate, SBP, and RPP were associated with 30-day mortality/HF hospitalization (hazard ratio [HR]: 1.17 per 5-bpm heart rate, HR: 1.20 per 10-mm Hg SBP, and HR: 1.02 per 100 bpm × mm Hg RPP; all P < 0.05). Baseline SBP was associated with 180-day mortality (HR: 0.88 per 10-mm Hg, P = 0.028). Though change in RPP was associated with 30-day mortality/HF hospitalization, the RPP baseline variable did not provide additional associative information with regard to outcomes when compared with assessment of baseline heart rate and SBP variables alone. CONCLUSIONS An increase in heart rate and SBP from baseline to discharge was associated with increased 30-day mortality/HF hospitalization in HFpEF patients with acute exacerbation. These findings suggest value in monitoring the trend of vital signs during HFpEF hospitalization.
