- AIMS: To assess the prognostic importance of high-sensitive C reactive protein (hsCRP) in patients with mild to moderate aortic valve stenosis during placebo or simvastatin/ezetimibe treatment in Simvastatin and Ezetimibe in Aortic Stenosis (SEAS).METHODS AND RESULTS: In 1620 SEAS patients, we measured lipids and hsCRP at baseline and after 1 year of treatment and registered during 4 years of follow-up major cardiovascular events (MCE) composed of ischaemic cardiovascular events (ICE) and aortic valve-related events (AVE). Simvastatin/ezetimibe reduced low-density lipoprotein cholesterol (3.49 (2.94 to 4.15) to 1.32 (1.02 to 1.69) vs 3.46 (2.92 to 4.08) to 3.34 (2.81 to 3.92) mmol/L) and hsCRP (2.1 (0.9 to 4.1) to 1.2 (0.6 to 2.4) vs 2.2 (0.9 to 4.9) to 1.8 (0.85 to 4.35) mg/L, all p<0.05) during the first year of treatment. In multivariable Cox regression analysis adjusting for traditional risk factors and baseline hsCRP, ICE was associated with a 1-year increase of hsCRP (HR=1.19 (95% CI 1.12 to 1.25), p<0.001) but not with active treatment (HRTreatment=0.86 (0.67 to 1.13), p=0.28). Patients in the top quartile of baseline hsCRP versus the rest were associated with a higher risk of MCE (HR=1.34(1.09 to 1.64), p=0.02). The prognostic benefit of reduction in hsCRP after 1 year was significantly larger (p<0.01 for interaction) in patients with high versus low baseline hsCRP; hence, a reduction in hsCRP abolished the difference in incidence of MCE between high versus low baseline hsCRP in patients with reduced hsCRP (31.1 vs 31.9%, NS) in contrast to patients with increased hsCRP.CONCLUSIONS: The treatment-associated reduction in ICE was in part related to a reduction in hsCRP but not in lipids. hsCRP reduction was associated with less MCE, especially in patients with high baseline hsCRP.TRIAL REGISTRATION: NCT00092677.

Journal article (peer-reviewed)abstract
- Introduction: Epidemiological studies suggest atherosclerosis as a common risk factor between cardiovascular diseases and erectile dysfunction (ED). We aimed to determine the association between erectile function and the biomarkers of subclinical atherosclerosis in 119 middle-aged healthy men from the general population. Methods: Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5). Serum levels of biomarkers of atherosclerosis: Apolipoprotein A, Apolipoprotein B, fibrinogen, and C-reactive protein (CRP) were measured. In addition, demographic data was collected. Results: The mean (SD) of age was 55 years (± 4.0). The prevalence of ED was 50%. There was a negative significant correlation between IIEF-5 and CRP levels (r = -0.20, p = 0.02), and BMI (r = -0.20, p = 0.03), respectively. No significant correlations between IIEF-5 and serum levels of Apolipoprotein A, Apolipoprotein B, and fibrinogen were found (p > 0.05). A positive significant correlation was found between BMI and fibrinogen (r = 0.20, p = 0.01), CRP (r = 0.30, p = 0.001). In a multivariate logistic regression model with IIEF-5 as the dependent variable, CRP was the only biomarker that predicted ED (odds ratio = 1.350; 95 % CI: 1.044-1.754). Conclusions: These results indicate that CRP is a biomarker of subclinical atherosclerosis associated with ED. This association seems to be linked to greater BMI among such men.

- 2016
-
In: Circulation. - 0009-7322 .- 1524-4539. ; 134:6, s. 455-468
-
Journal article (peer-reviewed)abstract
- Background: Evidence for treating hypertension in patients with asymptomatic aortic valve stenosis is scarce. We used data from the SEAS trial (Simvastatin Ezetimibe in Aortic Stenosis) to assess what blood pressure (BP) would be optimal. METHODS: A total of 1767 patients with asymptomatic aortic stenosis and no manifest atherosclerotic disease were analyzed. Outcomes were all-cause mortality, cardiovascular death, heart failure, stroke, myocardial infarction, and aortic valve replacement. BP was analyzed in Cox models as the cumulative average of serially measured BP and a time-varying covariate. RESULTS: The incidence of all-cause mortality was highest for average follow-up systolic BP >= 160 mm Hg (4.3 per 100 person-years; 95% confidence interval [CI], 3.1-6.0) and lowest for average systolic BP of 120 to 139 mm Hg (2.0 per 100 person-years; 95% CI, 1.6-2.6). In multivariable analysis, all-cause mortality was associated with average systolic BP < 120 mm Hg (hazard ratio [HR], 3.4; 95% CI, 1.9-6.1), diastolic BP >= 90 mm Hg (HR, 1.8; 95% CI, 1.1-2.9), and pulse pressure < 50 mm Hg (HR, 1.8; 95% CI, 1.1-2.9), with systolic BP of 120 to 139 mm Hg, diastolic BP of 70 to 79 mm Hg, and pulse pressure of 60 to 69 mm Hg taken as reference. Low systolic and diastolic BPs increased risk in patients with moderate aortic stenosis. With a time-varying systolic BP from 130 to 139 mm Hg used as reference, mortality was increased for systolic BP >= 160 mm Hg (HR, 1.7; P=0.033) and BP of 120 to 129 mm Hg (HR, 1.6; P= 0.039). CONCLUSIONS: Optimal BP seems to be systolic BP of 130 to 139 mm Hg and diastolic BP of 70 to 90 mm Hg in these patients with asymptomatic aortic stenosis and no manifest atherosclerotic disease or diabetes mellitus.

- AimsAnaemia and iron deficiency are constituents of the cardio-renal syndrome in chronic heart failure (CHF). We investigated the effects of i.v. iron in iron-deficient CHF patients on renal function, and the efficacy and safety of this therapy in patients with renal dysfunction. Methods and resultsThe FAIR-HF trial randomized 459 CHF patients with iron deficiency (ferritin <100 mu g/L, or between 100 and 299 mu g/L if transferrin saturation was <20%): 304 to i.v. ferric carboxymaltose (FCM) and 155 to placebo, and followed-up for 24 weeks. Renal function was assessed at baseline and at weeks 4, 12, and 24, using the estimated glomerular filtration rate (eGFR, mL/min/1.73m(2)), calculated from the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. At baseline, renal function was similar between groups (62.420.6 vs. 62.9 +/- 23.4 mL/min/1.73m(2), FCM vs. placebo). Compared with placebo, treatment with FCM was associated with an increase in eGFR [treatment effect: week 4, 2.11 +/- 1.21 (P = 0.082); week 12, 2.41 +/- 1.33 (P = 0.070); and week 24, 2.98 +/- 1.44 mL/min/1.73m(2) (P = 0.039)]. This effect was seen in all pre-specified subgroups (P > 0.20 for interactions). No interaction between the favourable effects of FCM and baseline renal function was seen for the primary endpoints [improvement in Patient Global Assessment (P = 0.43) and NYHA class (P = 0.37) at 24 weeks]. Safety and adverse event profiles were similar in patients with baseline eGFR <60 and 60 mL/min/1.73m(2). ConclusionsTreatment of iron deficiency in CHF patients with i.v. FCM was associated with an improvement in renal function. FCM therapy was effective and safe in CHF patients with renal dysfunction.

Journal article (peer-reviewed)abstract
- Objective: To investigate the association between serum levels of testosterone and biomarkers of subclinical atherosclerosis based on data from 119 middle-aged men of the general population. Methods: Testosterone, Apolipoprotein A-1 (ApoA-1), Apolipoprotein B (ApoB), Apolipoprotein B-to-Apolipoprotein A-1 ratio (ApoB-to-ApoA-1), high-sensitive C-reactive protein (hsCRP), and fibrinogen levels were measured. Data were also gathered based on age, BMI, waist circumference, smoking, alcohol consumption, and family history of cardiovascular diseases. Men were classified into two groups based on testosterone levels: hypogonadal (testosterone ≤12 nmol/L) and eugonadal men (testosterone >12 nmol/L). Results: When compared to eugonadal, the hypogonadal men were significantly older (56 years vs. 55 years, p = .03), had greater BMI (28 kg/cm2 vs. 26 kg/cm2, p = .01), and higher waist circumference (104 cm vs. 100 cm, p = .01). Moreover, ApoB, ApoB-to-ApoA-1 ratio, and hsCRP were significantly higher in hypogonadal men compared to eugonadal men (1.1 g/L vs. 1.0 g/L, p = .03), (0.8 vs. 0.7, p = .03), (3.3 mg/L vs. 2.0 mg/L, p = .01), respectively. On the other hand, ApoA-1 and fibrinogen levels did not differ significantly between groups (p > .05). In an adjusted multivariate regression analysis model, only ApoB showed a significant negative association with testosterone levels (β = −0.01; 95% CI = −0.02, −1.50; p = .04). Conclusion: Testosterone levels showed an inverse relation to ApoB, a biomarker implicated in subclinical atherosclerosis. These findings support the hypothesis that low testosterone levels play a role in atherosclerosis.

Journal article (peer-reviewed)abstract
- Objective: To study the associations between serum testosterone and risk factors for atherosclerosis in 119 men from general population. Methods: Systolic pressure, body mass index (BMI), testosterone, fasting glucose, glucose tolerance test, apolipoprotein A-1 (ApoA-1), apolipoprotein B (ApoB), and ApoB/ApoA-1 ratio were assessed. Subjects classified into hypogonadal (testosterone ≤ 12 nmol/l), and eugonadal men (testosterone > 12 nmol/l). Results: BMI (28 vs. 26 kg/m2, p = 0.01), systolic pressure (129 vs. 123 mmHg, p = 0.03), fasting glucose (5.9 vs. 5.5 mmol/l, p = 0.03), ApoB (1.1 vs. 1.0 g/l, p = 0.03), and ApoB/ApoA-1 ratio (0.8 vs. 0.7, p = 0.03) were higher in hypogonadal compared to eugonadal men, respectively. In adjusted multivariate regression analysis model, testosterone showed negative associations with BMI (β =-1.832, p = 0.030, 95% CI =-3.485-0.180), fasting glucose (β =-0.394, p = 0.011, 95% CI =-0.696-0.091), glucose tolerance test (β =-0.957, p = 0.045, 95% CI =-1.892-0.022), ApoB (β =-0.157, p = 0.017, 95% CI =-0.286-0.029), and ApoB/ApoA-1 ratio (β =-0.118, p = 0.046, 95% CI =-0.234-0.002). Conclusions: These results suggest an inverse association between testosterone levels and risk factors for atherosclerosis.
