RESUMO

INTRODUCTION: Obesity has been associated with increased arterial stiffness. Sex-differences in arterial stiffness in obesity have been less explored. AIM: To explore sex-differences in arterial stiffness by applanation tonometry in 323 women and 225 with overweight and obesity, free of cardiovascular disease. METHODS: Covariables of arterial stiffness were identified in multivariable linear regression analyses in the total cohort and separately in women and men. RESULTS: In the total study cohort, women had higher augmentation pressure (AP) and augmentation index (AIx), and lower carotid-femoral pulse wave velocity (cf-PWV) than men, independent of confounders (all p < 0.001). In sex-specific analyses, higher AP was associated with higher age and 24-hours systolic blood pressure (BP), and with lower heart rate in women (all p < 0.001), and with higher age and BP in men (all p < 0.001). Similarly, higher AIx was associated with higher age and BP, and lower body mass index (BMI) and heart rate in women (all p < 0.05), and with higher age in men (all p < 0.001). Higher cf-PWV correlated with higher age and BP in women (all p < 0.005), and additionally with higher heart rate and non-smoking in men (all p < 0.05). When replacing BMI with waist-hip ratio, higher waist-hip ratio was associated with higher cf-PWV in men only (p < 0.05). CONCLUSIONS: Among subjects with overweight and obesity, AP and AIx were higher in women, and cf-PWV was higher in men. Age and 24-hours systolic BP were the main factors associated with arterial stiffness in both sexes, while measures of adiposity had little impact on arterial stiffness.

RESUMO

PURPOSE: Hypertension is a major cardiovascular (CV) risk factor in ankylosing spondylitis (AS) patients. Less is known about the prevalence of CV organ damage in relation to hypertension status in AS patients. MATERIALS AND METHODS: CV organ damage was assessed by echocardiography, carotid ultrasound and pulse wave velocity (PWV) by applanation tonometry in 126 AS patients (mean age 49 ± 12 years, 39% women) and 71 normotensive controls (mean age 47 ± 11 years, 52% women). CV organ damage was defined as presence of abnormal left ventricular (LV) geometry, LV diastolic dysfunction, left atrial (LA) dilatation, carotid plaque or high pulse wave velocity (PWV). RESULTS: Thirty-four percent of AS patients had hypertension. AS patients with hypertension were older and had higher C-reactive protein (CRP) levels compared to AS patients without hypertension and controls (p < 0.05). The prevalence of CV organ damage was 84% in AS patients with hypertension, 29% in AS patients without hypertension and 30% in controls (p < 0.001). In multivariable logistic regression analyses, having hypertension was associated with a fourfold increased risk of CV organ damage independent of age, presence of AS, gender, body mass index, CRP, and cholesterol (odds ratio (OR) 4.57, 95% confidence interval (CI) 1.53 to 13.61, p = 0.006). In AS patients, presence of hypertension was the only covariable significantly associated with presence of CV organ damage (OR 4.40, 95% CI 1.40 to 13.84, p = 0.011). CONCLUSIONS: CV organ damage in AS was strongly associated with hypertension, pointing to the importance of guideline-based hypertension management in AS patients.


What is the context? Ankylosing spondylitis (AS) is an inflammatory disease primarily affecting the spine. Patients with AS have increased risk for cardiovascular disease. High blood pressure (hypertension) is both very common in AS patients, and a major risk factor for developing cardiovascular disease. Hypertension leads to structural and functional changes in the heart and arteries, referred to as cardiovascular organ damage. However, little is known about the prevalence of cardiovascular organ damage in AS patients with hypertension.What is new? Using ultrasound and tonometry, we assessed organ damage in the heart and arteries in AS patients with hypertension and compared them to AS patients with normal blood pressure as well as a group of healthy controls. We found that 84% of the AS patients with hypertension had cardiovascular organ damage, compared to 29% of AS patients with normal blood pressure and 30% of controls. Independent of other risk factors, hypertension was associated with a fourfold increased risk of cardiovascular organ damage in AS patients.What is the impact? These findings are important because cardiovascular organ damage is potentially reversible with treatment. Our results underline the significance of guideline-directed hypertension management in AS patients to reduce cardiovascular disease.

RESUMO

PURPOSE: To identify modifiable risk factors in early midlife associated with incident hypertension 26 years later in women and men. MATERIALS AND METHODS: We used data from 1025 women and 703 men in the community-based Hordaland Health Study examined at the mean age of 42 years (baseline) and after a 26-year follow-up. Patients with hypertension at baseline were excluded. Blood pressure (BP) was classified according to European guidelines. Factors associated with incident hypertension were identified in logistic regression analyses. RESULTS: At baseline, women had a lower average BP and a lower prevalence of high-normal BP (19% vs 37%, p < .05). Overall, 39% of women and 45% of men developed hypertension during follow-up (p < .05). Among those with high-normal BP at baseline, 72% of women and 58% of men developed hypertension (p < .01). In multivariable logistic regression analyses, high-normal BP at baseline was a stronger predictor of incident hypertension in women (odds ratio, OR 4.8, [95% confidence interval, CI 3.4-6.9]) than in men (OR 2.1, [95% CI 1.5-2.8]), p < .01 for sex interaction. A higher baseline body mass index (BMI) was associated with incident hypertension in both sexes. CONCLUSIONS: High-normal BP in midlife is a stronger risk factor for developing hypertension 26 years later in women than in men, independent of BMI.


There is a knowledge gap regarding the understanding of sex differences in hypertension and cardiovascular disease. The World Health Organisation has identified hypertension as the leading cause of morbidity and mortality in women.This manuscript focuses on sex differences in risk factors in early midlife associated with the development of hypertension 26 years later. We studied 1025 women and 703 men who participated in the community-based Hordaland Health Study at the age of 42 years, and after 26 years. Factors associated with hypertension were identified in statistical analyses.Our main findings were that having a high-normal blood pressure (systolic blood pressure 130­139 mmHg or a diastolic blood pressure 85­89 mmHg) in midlife was a significantly stronger risk factor for the development of hypertension in women than in men during follow-up. Having a higher body mass index in midlife was associated with the development of hypertension in both sexes.This study contributes to the understanding of sex differences in hypertension development and adds further knowledge regarding high-normal blood pressure as a particularly important risk factor for hypertension and cardiovascular disease in women.

RESUMO

Our aim was to test sex-specific associations of circulating markers of inflammation with blood pressure (BP) and incident hypertension in midlife. Participants in the Hordaland Health study (n = 3280, 56% women, mean age 48 years) were examined at baseline and followed for 6 years. Circulating levels of inflammatory markers including high-sensitive C-reactive protein (hs-CRP), neopterin, and pyridoxic acid ratio (PAr) index were measured at follow-up. The associations with systolic/diastolic BP and incident hypertension were tested in sex-specific linear- or logistic-regression analyses adjusted for body mass index, serum triglycerides, creatinine, physical activity, smoking and diabetes. At follow-up, women had lower mean BP than men (124/72 vs. 130/78 mmHg, p < 0.001). Higher hs-CRP was significantly associated with greater systolic and diastolic BP (standardized ß = 0.07 and ß = 0.09, both p < 0.01) in women, but not in men. Higher neopterin was associated with higher diastolic BP in women and higher PAr index was associated with higher diastolic BP in women and higher systolic and diastolic BP in men (all p < 0.01). Compared to hs-CRP < 1 mg/l, higher levels of hs-CRP 1-<3 mg/l and hs-CRP ≥ 3 mg/l were associated with new-onset hypertension only in women (odds ratio (OR) 1.74, 95% CI 1.20-2.53 and OR 1.87, 95% CI 1.20-2.90). Sex-interactions were found for hs-CRP and neopterin in models on incident hypertension and diastolic BP, respectively (both p < 0.05). Higher levels of circulating markers of inflammation were associated with higher BP and incident hypertension in a sex-specific manner. Our results suggest a sex-specific interaction between cardiovascular inflammation and BP in midlife.

RESUMO

Objective: Psoriasis is an immune mediated disorder associated with T cell activation and cardiovascular disease (CVD). We explored the association of inflammation with left ventricular (LV) remodelling in psoriasis patients receiving treatment with the tumour necrosis factor-α (TNF-α) blocker infliximab. Methods: Psoriasis patients (n = 47, age 47 ± 14 years, 66% men) and 99 control subjects without psoriasis (age 47 ± 11 years, 72% men) were examined by echocardiography in a cross-sectional study. LV remodelling was assessed by LV mass index for height in the allometric power of 2.7. Serum concentrations of C-reactive protein (CRP), serum amyloid A (SAA), neopterin, kynurenine:tryptophan ratio (KTR) and the pyridoxic acid ratio (PAr) index were measured. Results: Serum concentration of neopterin (p = .007) was higher in psoriasis patients, while the other inflammatory biomarkers had similar levels. LV mass index was lower in patients than controls (35.6 ± 9.6 g/m2.7 vs. 40.3 ± 9.8 g/m2.7, p = .008). In the total study population, serum SAA (ß = 0.18, p = .02), KTR (ß = 0.20, p = .02) and the PAr index (ß = 0.26, p = .002) were all associated with higher LV mass index independent of age, sex, body mass index, hypertension, smoking, renal function and psoriasis. Also in psoriasis patients, higher SAA level (ß = 0.34, p = .02), KTR (ß = 0.32, p = .02) and the PAr index (ß = 0.29, p = .05) were associated with higher LV mass index independent of body mass index, hypertension and diabetes. Conclusion: Higher levels of the inflammatory biomarkers SAA, KTR and the PAr index were associated with greater LV mass index in psoriasis patients, indicating a role of chronic inflammation in LV remodelling evident even during treatment with TNF-α blockers.

RESUMO

OBJECTIVE: We compared persistent cardiac organ damage in patients treated surgically or medically for primary aldosteronism. METHODS: Eighty-four patients (age 57 ±â€Š11 years, 27% women) with primary aldosteronism underwent echocardiography at time of diagnosis and after one year of treatment (49% adrenalectomy, 51% medical treatment). Persistent cardiac organ damage was defined as presence of left ventricle (LV) hypertrophy, low LV midwall shortening, global longitudinal strain and/or enlarged left atrium both at baseline and at follow-up. RESULTS: At one year, a significant regression of LV hypertrophy was observed in surgically (44 vs. 22%, P  = 0.039), but not in medically treated patients (60 vs. 51%, P = 0.206). The prevalence of enlarged left atrium was reduced in both groups (both P < 0.001), whereas systolic myocardial function remained unchanged. In multivariable logistic regression analysis, medical treatment [odds ratio (OR) 4.88 (95% confidence interval (CI) 1.26-18.88)] was a strong predictor of persistent LV hypertrophy independent of higher BMI [OR 1.20 (95% CI 1.04-1.38)] and presence of diabetes [OR 6.48 (95% CI 1.20-34.83), all P < 0.05]. Persistently low midwall shortening was associated with suppressed plasma renin after one year [OR 6.11 (95% CI 1.39-26.7)] and lower renal function [OR 0.96 (95% CI 0.94-0.99), both P < 0.05]. The strongest predictor of persistently low global longitudinal strain was higher HbA1c [OR 2.37 (95% CI 1.12-5.02), P = 0.024]. CONCLUSION: Persistent cardiac organ damage was more common in the medical treatment group and associated with incomplete aldosterone blockade, impaired renal function and presence of metabolic comorbidities.http://links.lww.com/HJH/B925.

RESUMO

AIMS: Hypertension has been suggested as a stronger risk factor for acute coronary syndromes (ACS) in women than men. Whether this also applies to stage 1 hypertension [blood pressure (BP) 130-139/80-89 mmHg] is not known. METHODS AND RESULTS: We tested associations of stage 1 hypertension with ACS in 12 329 participants in the Hordaland Health Study (mean baseline age 41 years, 52% women). Participants were grouped by baseline BP category: Normotension (BP < 130/80 mmHg), stage 1 and stage 2 hypertension (BP ≥140/90 mmHg). ACS was defined as hospitalization or death due to myocardial infarction or unstable angina pectoris during 16 years of follow-up. At baseline, a lower proportion of women than men had stage 1 and 2 hypertension, respectively (25 vs. 35% and 14 vs. 31%, P < 0.001). During follow-up, 1.4% of women and 5.7% of men experienced incident ACS (P < 0.001). Adjusted for diabetes, smoking, body mass index, cholesterol, and physical activity, stage 1 hypertension was associated with higher risk of ACS in women [hazard ratio (HR) 2.18, 95% confidence interval (CI) 1.32-3.60], while the association was non-significant in men (HR 1.30, 95% CI 0.98-1.71). After additional adjustment for systolic and diastolic BP, respectively, stage 1 diastolic hypertension was associated with ACS in women (HR 2.79 [95% CI 1.62-4.82]), but not in men (HR 1.24 [95% CI 0.95-1.62]), while stage 1 systolic hypertension was not associated with ACS in either sex. CONCLUSION: Among subjects in their early 40s, stage 1 hypertension was a stronger risk factor for ACS during midlife in women than in men.

RESUMO

We explored the association between subclinical cardiac organ damage (OD) with comorbidities and psoriasis severity in 53 psoriasis patients on infliximab treatment (age 47 ± 15 years, 30% women) and 99 controls without psoriasis (age 47 ± 11 years, 28% women). Cardiac OD was assessed by echocardiography as the presence of increased left ventricular (LV) relative wall thickness (RWT), LV hypertrophy or dilated left atrium. Psoriasis severity was graded using the psoriasis area and severity index (PASI). The prevalence of hypertension was 66% in psoriasis vs. 61% in controls (p = 0.54) and cardiac OD seen in 51 and 73%, respectively (p = 0.007). Psoriasis was associated with a lower prevalence of cardiac OD (odds ratio (OR) 0.32, 95% confidence interval (CI) 0.13-0.77, p = 0.01) independent of age, sex, smoking, body mass index, and hypertension. Among psoriasis patients, hypertension was associated with increased risk of subclinical cardiac OD (OR 6.88, 95% CI 1.32-35.98, p = 0.02) independent of age, sex, and body mass index. PASI at treatment initiation was associated with a higher RWT at follow-up, independent of sex, age, and hypertension (ß 0.36, p = 0.006) while no association with current PASI was found. In conclusion, cardiac OD was less prevalent in psoriasis patients on infliximab treatment than controls. Hypertension was the major covariable for subclinical cardiac OD in psoriasis.

RESUMO

Purpose: We aimed to identify sex-specific factors associated with increase in blood pressure (BP) and incident hypertension in early midlife.Materials and methods: 2,008 women and 1,610 men aged 40-43 years were followed for six years in the Hordaland Health Study. Participants taking antihypertensive medication at baseline were excluded. High-normal BP was defined as baseline BP 130-139/85-89 mmHg, and incident hypertension as BP≥140/90 mmHg or use of antihypertensive medication at follow-up.Results: During follow-up, an increase in systolic (SBP) and diastolic (DBP) BP was observed in 54% and 30% of women vs. 44% and 41% of men, respectively (both p<0.001). In both sexes higher baseline body mass index (BMI) and increases in BMI and serum lipids were associated with increases in SBP and DBP during follow-up (all p<0.05). Incident hypertension was more common in men (14 vs.11%, p<0.01), and predicted by higher BMI and high-normal BP at baseline in both sexes, and by higher serum triglyceride level in women (all p<0.01). Conclusion: In the Hordaland Health Study, BP development differed between women and men in early midlife. The main factors associated with BP increase in both sexes were higher BMI, weight gain and increases in serum lipids.

RESUMO

OBJECTIVE: Statin treatment has been associated with reduction in blood pressure and arterial stiffness in patients with inflammatory joint diseases (IJD). We tested whether statin treatment also was associated with regression of preclinical cardiac organ damage in IJD patients. METHODS: Echocardiography was performed in 84 IJD patients (52 RA, 20 ankylosing spondylitis, 12 psoriatric arthritis, mean age 61 (9) years, 63% women) without known cardiovascular disease before and after 18 months of rosuvastatin treatment. Preclinical cardiac organ damage was identified by echocardiography as presence of left ventricular (LV) hypertrophy, LV concentric geometry, increased LV chamber size and/or dilated left atrium. RESULTS: At baseline, hypertension was present in 63%, and 36% used biologic DMARDs (bDMARDs). Preclinical cardiac organ damage was not influenced by rosuvastatin treatment (44% at baseline vs 50% at follow-up, P = 0.42). In uni- and multivariable logistic regression analyses, risk of preclinical cardiac organ damage at follow-up was increased by higher baseline body mass index [odds ratio (OR) 1.3, 95% CI: 1.1, 1.5, P = 0.01] and presence of preclinical cardiac organ damage at baseline (OR 6.4, 95% CI: 2.2, 18.5, P = 0.001) and reduced by use of bDMARDs at follow-up (OR 0.3, 95% CI: 0.1, 0.9, P = 0.03). CONCLUSION: Rosuvastatin treatment was not associated with a reduction in preclinical cardiac organ damage in IJD patients after 18 months of treatment. However, use of bDMARDS at follow-up was associated with lower risk of preclinical cardiac organ damage at study end, pointing to a possible protective cardiac effect of bDMARDs in IJD patients.

RESUMO

OBJECTIVE: We studied the impact of concomitant hypertension on left ventricular (LV) systolic myocardial function and geometry in apparently healthy women and men with increased BMI. MATERIAL AND METHODS: We performed a cross-sectional analysis of 535 participants (59% women) with BMI greater than 27 kg/m without known cardiovascular disease enrolled in the FAT associated CardiOvasculaR dysfunction (FATCOR) study. Hypertension was defined as use of antihypertensive treatment or elevated 24-h ambulatory blood pressure. Abnormal LV geometry was identified as increased relative wall thickness and/or LV mass index. Systolic myocardial function was assessed by midwall shortening (MWS) and speckle tracking peak global longitudinal strain (GLS). RESULTS: Hypertensive participants were older (49 vs. 46 years), had higher BMI and waist circumference, higher prevalences of diabetes and abnormal LV geometry (29 vs. 16%), and lower GLS (-19 vs. -20%) and MWS (16.3 vs. 17.1%) compared with normotensive participants (all P < 0.01). In multivariable linear regression analyses, hypertension was associated with lower GLS (ß=0.11, P = 0.035) and lower MWS (ß=0.09, P = 0.029) independent of sex, diabetes, LV hypertrophy, ejection fraction, and waist circumference. Hypertension was also associated with presence of abnormal LV geometry [odds ratio 1.74 (95% confidence interval 1.04-2.89), P = 0.035) independent of the same confounders. When replacing waist circumference with BMI in the models, hypertension retained its association with lower myocardial function, whereas the association with abnormal LV geometry was attenuated. CONCLUSION: In participants with increased BMI without known clinical cardiovascular disease, concomitant hypertension was associated with lower systolic myocardial function and more abnormal LV geometry.

RESUMO

OBJECTIVES: Catheter ablation is regarded as first-line therapy for symptomatic atrioventricular nodal reentry tachycardia (AVNRT). Ablation induces intended myocardial damage and the extent of myocardial damage may differ between ablation methods. The objective of this MAGMA AVNRT(NCT00875914) substudy was to compare high-sensitive cardiac troponin T (hs-cTnT) levels as a surrogate marker for myocardial damage after manually guided (MAN) AVNRT ablation versus AVNRT ablation using remote magnetic navigation (RMN). DESIGN: In total, 70 patients (mean age 44 ± 14 years, 26% male) undergoing catheter ablation for AVNRT in the MagMa-AVNRT-Trial were randomized to remote magnetic navigation (n = 34, 49%) or manually guided catheter ablation (n = 36, 51%). hs-cTnT was measured the day after the procedure. RESULTS: The median follow-up time was 6.2 ± 1.1 years. Acute success was 100% in both groups. hs-cTnT release was significantly lower in the remote magnetic navigation group (52 ng/L versus 95 ng/L, p < .01), even though the ablation time was longer and number of applications was higher with remote magnetic navigation (4.2 min vs 2.8 min, p = .017; 4.9 vs 3.3 applications, p = .01). hs-cTnT released per minute ablation time was also lower with remote magnetic navigation (12 ng/L versus 34 ng/L, p < .01). Both groups exhibited similar clinical long-term follow up regarding recurrence and complications. CONCLUSION: Remote magnetic navigation controlled catheter ablation of AVNRT has similar clinical outcome, but leads to less hs-cTnT release than manually guided catheter ablation. This might correspond to less unintended myocardial damage with RMN, which might be advantageous in complex ablation procedures.
