Sex Difference in the Association Between Brachial Pulse Pressure and Coronary Artery Disease: The Korean Women's Chest Pain Registry (KoROSE).

ABSTRACT: This study was performed to investigate the association between brachial pulse pressure (PP) and the presence/extent of obstructive coronary artery disease (CAD) in men and women. Study data were obtained from a nation-wide registry composed of 632 patients (173 men and 459 women, 58.1±10.5 years) with suspected CAD who underwent invasive coronary angiography. PP was higher in patients with obstructive CAD (≥50% stenosis) than those without CAD in both sexes (P=.032 in men; P<.001 in women). However, PP increased proportionally with the increasing number of obstructed coronary arteries in women (P<.001) but not in men (P=.070). Multiple logistic-regression analyses demonstrated that higher PP (≥50.5 mm Hg) was an independent factor for determining obstructive CAD even after controlling for potential confounders in women (odds ratio, 2.83; 95% confidence interval, 1.40-5.73; P=.004). These results were consistent in 173 selected women matched with 173 men based on age and CAD severity. In conclusion, the association between brachial PP and obstructive CAD was more pronounced in women than in men. Brachial PP can be a simple and useful indicator of CAD especially in women.

Brachial pulse pressure in acute heart failure. Results of the Heart Failure Registry.

Project description:AimsTo investigate the still uncertain independent prognostic impact of pulse pressure (PP) in acute heart failure (HF), in particular across the left ventricular ejection fraction (EF) phenotypes, and the potential contribution of PP in outlining the individual phenotypes.Methods and resultsWe prospectively evaluated 1-year death and rehospitalization in 4314 patients admitted for acute HF grouped by EF and stratified by their PP level on admission. In HF with reduced (< 40%) EF (HFrEF), the highest quartiles of PP had the lowest unadjusted [hazard ratio (HR) 0.77, 95% confidence interval (CI) 0.61-0.98] and adjusted (HR 0.64 0.50-0.82) risk of 1 year all cause death compared to the lowest quartile. Its prognostic impact was partially mediated by systolic blood pressure (SBP). In HF with preserved (≥ 50%) EF (HFpEF), the intermediate quartile of PP showed the lowest 1 year all cause mortality in unadjusted (HR 0.598, CI 0.416-0.858) and adjusted (HR 0.55, 95% CI 0.388-0.801) models with no relationship with SBP. In a receiver operating characteristic analysis, a combination of PP > 60 mmHg and SBP > 140 mmHg was associated to a preserved EF with a high performance value. No prognostic significance of PP was found in the HF with mid-range EF subgroup.ConclusionsIn acute HFrEF, there is an almost linear inverse relation between mortality and PP, partly mediated by SBP. In HFpEF, a J-shaped relationship between mortality and PP was present with a better prognosis at the nadir. A combination of PP > 60 mmHg with SBP > 140 mmHg may be clinically helpful as marker of a preserved left ventricular EF.

Sex differences in coronary angiographic findings in patients with stable chest pain: analysis of data from the KoRean wOmen'S chest pain rEgistry (KoROSE).

Project description:BackgroundFocused evaluations on potential sex differences in the angiographic findings of the coronary arteries are scarce. This study was performed to compare the angiographic extent and localization of coronary stenosis between men and women.MethodsA total of 2348 patients (mean age 62.5 years and 60% women) with stable chest pain undergoing invasive coronary angiography (CAG) were recruited from the database of the nation-wide chest pain registry. Obstructive coronary artery disease (CAD) was defined as ≥ 50% stenosis of the left main coronary artery and/or ≥ 70% stenosis of any other epicardial coronary arteries.ResultsAlthough women were older than men (64.4 ± 10.3 vs. 59.5 ± 11.4 years, P < 0.001), men had worse risk profiles including high blood pressure, more frequent smoking and elevated triglyceride and C-reactive protein. The prevalence of obstructive CAD was significantly higher in men than in women (37.0% vs. 28.4%, P < 0.001). Men had a higher prevalence of LM disease (10.3% vs. 3.5%, P < 0.001) and three-vessel disease (16.1% vs. 9.5%, P = 0.007) compared to women. In multiple binary logistic regression analysis, the risk of men having LM disease or three-vessel disease was 7.4 (95% confidence interval 3.48-15.97; P < 0.001) and 2.7 (95% confidence interval 1.57-4.64; P < 0.001) times that of women, respectively, even after controlling for potential confounders.ConclusionsIn patients with chest pain undergoing invasive CAG, men had higher obstructive CAD prevalence and more high-risk angiographic findings such as LM disease or three-vessel disease.

Brachial pulse pressure is associated with the presence and extent of coronary artery disease in stable angina patients: a cross-sectional study.

Project description:BACKGROUND:Previous epidemiological evidence has identified many risk factors for coronary artery disease (CAD). Pulse pressure (PP) was reported to be associated with CAD. However, more attention was paid to aortic PP than to brachial PP. This cross-sectional study aimed to investigate the direct relationship between brachial PP and the presence and extent of CAD in stable angina patients. METHODS:We recruited a total of 1118 consecutive patients with stable chest pain suspected of CAD. After screening with exclusion criteria, 654 patients were finally included in our study. Every patient underwent both blood pressure measurement and selective coronary angiography. Univariate and multivariate analysis were performed to analyze the association between PP and the presence and extent of CAD. RESULTS:This study revealed that brachial PP was an independent correlate of multivessel CAD. In multivariate generalized linear regression model, increasing brachial PP (per 1?mmHg) were associated with the increased number of diseased vessels (??=?0.01, SE?=?0.00, P?<?0.0001). Binary logistic regression analysis further confirmed this association. The risk of multivessel CAD increased significantly in patients with brachial PP???60?mmHg (OR?=?1.69, 95% CI?=?1.14-2.48, P?=?0.0084) and as per 1?mmHg increased in brachial PP (OR?=?1.02, 95% CI?=?1.01-1.03, P?=?0.0002), independent of age, gender, body mass index (BMI), smoking, diabetes, hypercholesterolemia and creatinine (Cr). This association was still of statistical significance in subgroup analysis of hypertension and diabetes. CONCLUSION:Increasing brachial PP was significantly and independently associated with increased risk of multivessel coronary disease in stable angina patients. The association of brachial PP with CAD was more pronounced in hypertension group than in non-hypertension one.

The association of brachial-ankle pulse wave velocity with coronary artery disease evaluated by coronary computed tomography angiography.

Project description:The aim of this study was to investigate whether brachial-ankle pulse wave velocity (baPWV) is associated with the severity of coronary artery disease (CAD) assessed by coronary computed tomography angiography (CCTA), and to evaluate baPWV as a predictor of obstructive CAD on CCTA. A total of 470 patients who underwent both baPWV and CCTA were included. We evaluated stenosis degree and plaque characteristics on CCTA. To estimate the severity of CAD, we calculated the number of segment with plaque (segment involvement score; SIS), stenosis degree-weighted plaque score (segment stenosis score; SSS), and coronary artery calcium score (CACS). The mean baPWV was 1,485 ± 315 cm/s (range, 935-3,175 cm/s). Non-obstructive (stenosis < 50%) and obstructive (stenosis ≥ 50%) CAD was found in 129 patients (27.4%) and 144 (30.6%), respectively. baPWV in patients with obstructive CAD was higher than that of patients with non-obstructive (1,680 ± 396 cm/s versus 1,477 ± 244 cm/s, P < 0.001) or no CAD (1,680 ± 396 cm/s versus ± 196 1,389 cm/s, P < 0.001). baPWV showed significant correlation with SSS (r = 0.429, P < 0.001), SIS (r = 0.395, P < 0.001), CACS (r 0.346, P < 0.001), and the number of segment with non-calcified plaque (r 0.092, P = 0.047), mixed plaque (r = 0.267, P < 0.001), and calcified plaque (r = 0.348, P < 0.001), respectively. The optimal baPWV cut-off value for the detection of obstructive CAD was 1,547 cm/s. baPWV ≥ 1,547 cm/s was independent predictor for the obstructive CAD. In conclusion, baPWV is well correlated with the severity of CAD evaluated by CCTA. baPWV has the potential to predict severity of coronary artery atherosclerosis.

Relationship between brachial-ankle pulse wave velocity and invasively measured aortic pulse pressure.

Project description:Although brachial-ankle pulse wave velocity (baPWV) has been widely used as an index of arterial stiffness, no consensus exists about whether baPWV can reflect central aortic stiffness. The authors investigated the association between baPWV and invasively measured aortic pulse pressure (APP) in a total of 109 consecutive patients (mean age, 62.3 ± 11.3 years; 67.9% men). Most patients (91%) had obstructive coronary artery disease, and mean baPWV and APP values were 1535 ± 303 cm/s and 66.8 ± 22.5 mm Hg, respectively. In univariate analysis, there was a significant linear correlation between baPWV and APP (r = .635, P < .001). The correlation between baPWV and APP remained significant even after controlling for potential confounders (β = 0.574, P < .001; R2 = .469). Arterial stiffness measured by baPWV showed a strong positive correlation with invasively measured APP, independent of clinical confounders. Therefore, baPWV can be a good marker of central aortic stiffness.

Relationships between blood pressure measurements and target organ damage: Data from the Korea women's chest pain registry.

Project description:This study was performed to investigate the association between four BP measurements (systolic blood pressure [SBP], diastolic blood pressure [DBP], mean arterial pressure [MAP], and pulse pressure [PP]) and four TOD parameters (left ventricular mass index [LVMI], E/e', estimated glomerular filtration rate [eGFR], and obstructive coronary artery disease [CAD]). Data were obtained from a nation-wide registry, composed of 652 patients (471 women, 58.4 ± 10.5 years) with suspected CAD who underwent elective invasive coronary angiography (CAG). A total of 217 patients (33.2%) had obstructive CAD (≥50%). In multivariable analyses, E/e' was associated with SBP, MAP and PP, and CAD was associated with SBP and PP (P < 0.05 for each). All four BP measurements were not associated with LVMI and eGFR (P > 0.05 for each). In patients undergoing elective invasive CAG, SBP, and PP had stronger relationships with E/e' and CAD than DBP and MAP.

Aortic pulse pressure is associated with the localization of coronary artery disease based on coronary flow lateralization.

Project description:BACKGROUND:Aortic pulse pressure (APP) is related to arterial stiffness and associated with the presence and extent of coronary artery disease (CAD). Besides, the left coronary artery (LCA) has a predominantly diastolic flow while the right coronary artery (RCA) receives systolic and diastolic flow. Thus, we hypothesized that increased systolic-diastolic pressure difference had a greater atherogenic effect on the RCA than on the LCA. METHODS:A random sample of 433 CAD patients (145 females, 288 males, mean age 65.0 ± 11.1 years) undergoing coronary angiography at Staten Island University Hospital between January 2005 and May 2008 was studied. Coronary lesion was defined as a ?50% luminal stenosis. Patients were divided into three groups, with isolated LCA lesions (n = 154), isolated RCA lesions (n = 36) or mixed LCA and RCA lesions (n = 243). RESULTS:APP differed significantly between groups, being highest when the RCA alone was affected (67.6 ± 20.3 mm Hg for LCA vs. 78.8 ± 22.0 for RCA vs. 72.7 ± 22.6 for mixed, P = 0.008 for analysis of variance (ANOVA)). Age and gender were not associated with CAD location. Heart rate was associated with CAD location, lowest in RCA group, and negatively correlated with APP. However, left ventricular ejection fraction (LVEF) was lower in the mixed CAD group and positively correlated with APP. The association between APP and right-sided CAD persisted in multivariate logistic regression adjusting for confounders, including heart rate, LVEF and medication use. A similar but less significant pattern was seen with brachial arterial pressures. CONCLUSIONS:Aortic pulse pressure may affect CAD along with coronary flow phasic patterns.

Prognostic Significance of Pulse Pressure and Other Blood Pressure Components for Coronary Artery Disease in Type 1 Diabetes.

Project description:BACKGROUND:To compare in individuals with type 1 diabetes the prediction of incident coronary artery disease (CAD) by components of resting blood pressure-systolic, diastolic, pulse pressure, and mean arterial pressure. METHODS:In 605 participants without known CAD at baseline and followed sequentially for 25 years, we used Cox modeling built for each blood pressure component associated with incident CAD, overall and stratified by age (<35 and ?35 years) or hemoglobin A1c (HbA1c) (<9% and ?9%). RESULTS:Baseline mean age and diabetes duration were 27 and 19 years, respectively. We observed an early asymptote and then fall in diastolic blood pressure in their late 30s and early 40s in this group of type 1 diabetes individuals, followed by an early rise of pulse pressure. Adjusted hazard ratios (HR) (95% con) for CAD associated with 1 SD pressure increase were 1.35 (1.17, 1.56) for systolic pressure; 1.30 (1.12, 1.51) for diastolic pressure; 1.20 (1.03, 1.39) for pulse pressure; and 1.35 (1.17, 1.56) for mean arterial pressure. Pulse pressure emerged as a strong predictor of CAD at age ? 35 years (HR: 1.49 [1.15, 1.94]) and for HbA1c ? 9% (HR: 1.32 [1.01, 1.72]). CONCLUSIONS:Individuals with type 1 diabetes may manifest early vascular aging by an early decline in diastolic blood pressure and rise in pulse pressure, the latter parameter becoming a comparable to systolic blood pressure in predictor incident CAD in those aged over 35 years and those with poor glycemic control.

A Comparative Study of Brachial-Ankle Pulse Wave Velocity and Heart-Finger Pulse Wave Velocity in Korean Adults.

Project description:Arterial stiffness is considered an index of vascular aging. The brachial-ankle pulse wave velocity (baPWV) method is widely used because of its proven effectiveness; and the pulse wave velocity measurement method using both electrocardiogram (ECG) and photoplethysmogram (PPG) is actively being studied due to the convenience of measurement and the possibility of miniaturization. The aim of this study was to evaluate and compare the effects of age and gender in Korean adults using both the baPWV method and the PWV method with ECG and finger PPG (heart-finger PWV). The measurements have been carried out for 185 healthy subjects of Korean adults, and the results showed that the baPWV was highly correlated with age in both genders (r = 0.94 for both males and females). However, the correlation values in heart-finger PWV measurement were significantly lower than those of baPWV (r = 0.37 for males and r = 0.71 for females). Although the heart-finger PWV method is suitable for mobile applications because it can be easily miniaturized while maintaining its signal quality, these results show that the heart-finger PWV method is not as effective as baPWV at evaluating the arterial stiffness.

Data on the clinical usefulness of brachial-ankle pulse wave velocity in patients with suspected coronary artery disease.

Project description:Brachial-artery pulse wave velocity (baPWV) is a simple and reliable tool for measurement of arterial stiffness. Our previous studies suggested that baPWV is associated with the presence and severity of coronary artery disease (CAD) and the risk of cardiovascular events. In the present data article, we provided supplementary data supporting the independent prognostic value of arterial stiffness, assessed by baPWV, in patients with suspected CAD (Hwang et al., 2017) [1]. The data was obtained from 523 patients undergoing coronary CT angiography (CCTA), and baPWV was measured at the time of CCTA. Patients with vulnerable coronary plaque or obstructive CAD on CCTA had higher age, more cardiovascular risk factors, and higher baPWV values. Given the significant association between high baPWV and the presence of vulnerable plaque or obstructive CAD as shown in this data article, the prognostic value of baPWV was further assessed in subgroups divided according to the CCTA findings (vulnerable plaque or obstructive CAD). In each subgroup by CCTA findings, multivariable Cox proportional hazard model analysis showed that high baPWV was an independent risk factor for cardiovascular events even after adjusting for clinical risk factors.
