Risque Cardiovasculaire

L’hypertension artérielle systémique représente un facteur de risque cardiovasculaire majeur à l’origine de comorbidités et de mortalité. Les manifestations oculaires de l’HTA en particulier la rétinopathie hypertensive sont les atteintes les plus fréquentes de cette affection, parfois le diagnostic de l’HTA n’est mis en évidence qu’au décours de l’exploration d’une complication ou d’un accident cardiovasculaire (cas des patients présentés dans l’article). Les complications oculaires fréquentes sont les hémorragies sous-conjonctivales et de façon plus grave on retrouve les occlusions veineuses, les neuropathies optiques ischémiques et de façon plus rare mais fonctionnellement fatale les occlusions artérielles rétiniennes ou choroïdiennes. Un dépistage est conseillé en cas d’hypertension mal contrôlée ou aiguë en particulier chez les patients diabétiques, car l’HTA est à l’origine d’une aggravation de la rétinopathie diabétique.

Abstract Objectives First generation baroreflex activation therapy (BAT) devices showed clinical efficacy in patients with drug-resistant arterial hypertension (AHT), but the safety profile was insufficient. Data regarding efficacy of second-generation devices were generated mostly from office blood pressure (BP) measurements or short-term 24-hour ambulatory blood pressure measurements (ABPM). We present a mid-term prospective registry to evaluate the efficacy and safety of recent BAT devices. Purpose The purpose of our study was to find a method that helps patients with drug-resistant arterial hypertension to control their blood pressure. Further we sought to reduce the overall amount of antihypertensive drugs to lessen side effects, as well as the effects of polypharmacy. Methods All patients receiving Barostim neo between November 2013 and June 2019 for resistant AHT were prospectively included into this observational study. ABPM was performed at baseline, in 3-month intervals in the first year after BAT implantation and in 6-month intervals afterwards for up to 42 months. Patients were assigned into two groups of responders and non-responders. Non-responders had a mean blood pressure drop (BPD) below 5mmHg. Responders in turn were categorized into 3 sub-groups (low-BPD between 5–9 mmHg, medium-BPD between 10–19 mmHg and high-BPD ≥20 mmHg). The primary efficacy end-points were changes in systolic and diastolic BP and number of antihypertensive medications. The primary safety end point was BAT-related major adverse events (MAE). Results 64 patients (mean age 63 years, 67% males) were included. Only patients who completed a 24-hour ABPM during a follow up were counted in the statistical analysis. We had an overall responder rate of 67.8%. Out of those 15.4% had low-BPD, 38.4% medium-BPD and 46.2% had a high-BPD. Systolic BP decreased over the 3.5-years period from 168±17 mmHg to 149±19 mmHg (n=19, mean change −18.8 mmHg; 95% confidence interval [CI]: −29.32 to −8.36; p<0.0007). Diastolic BP decreased from 97±16 to 85±12 mmHg (n=19, mean change −11.7 mmHg; 95% CI: −19.2 to −4.2; p<0.0021). The mean number of antihypertensive drugs was reduced from 6.9±1.3 to 5.2±1.5 (n=19, mean change −1.7; 95% CI: −0.8 to −0.27; p<0.0009). The time course of primary end-points is shown in Fig.1. Freedom from BAT-related MAE was 93.5%. 4 perioperative complications (1 pocket bleeding, 1 pocket infection, 1 N. hypoglossus palsy, 1 hoarseness) resolved without residual side effects. There were five non BAT related deaths (7,8%) in the follow up period. Conclusion Systolic and diastolic ABP, as well as number and dosage of antihypertensive drugs decreased significantly during 3.5-years follow-up after Barostim neo implantation in 64 consecutive patients (of whom 62 completed at least one follow-up). No MAE associated with BAT were observed after the perioperative period. However, further controlled trials are needed to confirm the long-term efficacy of BAT. Figure 1.

Abstract Background Right ventricular (RV) function is a major determinant of survival in patients with pulmonary arterial hypertension (PAH). In our previous study, we confirmed that increased RV fluorodeoxyglucose (FDG) uptake in positron emission tomography (PET) (presented as higher ratio of FDG uptake of RV to LV) was associated with progressive RV dysfunction and preceded hemodynamic and clinical deterioration in PAH patients. Now, we obtained second PET/MRI assessments of the study group after 2-years of PAH-targeted treatment. Aim The aim of the study was to obtain change of cardiac FDG uptake in PAH patients after follow-up period and to indicate factors mainly affecting this change. Methods Twenty-eight PAH patients (51.32±15.91 years) had simultaneous PET/MRI scans performed during baseline visit. FDG was used and its uptake was quantified as mean standardized uptake value (SUV) for both left (LV) and RV. Second PET/MRI assessments were done after 2 years in the group of twenty patients (four deaths, four patients did not agree to perform additional scans). Results After follow-up period, we observed significant change of MRI-derived RV ejection fraction (45±10% to 51.2±12.7%, p=0.03), and improvement in hemodynamic parameters obtained from right heart catheterization (RHC) e.g. mean pulmonary artery pressure, mPAP (48.5±17.2 to 41.8±17.1 mmHg, p=0.01) and pulmonary vascular resistance, PVR (8.7±5.3 to 7.0±4.2 WU, p=0.04). Follow-up SUVRV/SUVLV ratio significantly correlated with follow-up RV hemodynamic parameters confirming relationship between RV function and cardiac metabolic alterations (Table 1). Interestingly, patients who had improvement in SUVRV/SUVLV (lower follow-up value than baseline, n=11) had significantly higher mPAP at baseline visit (58.9±18.7 vs 40.3±11.8 mmHg, p=0.02), suggesting that RV FDG accumulation in advanced PAH may decrease after the PAH-specific treatment in accordance with the degree of reduction in the pulmonary vascular resistance. Conclusion Impaired RV function is associated with increased glucose uptake of RV myocytes estimated by FDG PET in PAH patients. Targeted treatment may improve RV function and thus affect previously altered cardiac glucose uptake. Funding Acknowledgement Type of funding source: Public grant(s) – National budget only.

Abstract Background Asymptomatic hyperuricemia (AHU) is defined as elevated serum uric acid (UA) concentration without symptoms. This study aimed to determine the effects of AHU treatment with allopurinol on selected hypertension mediated organ damage (HMOD) indices in patients with uncomplicated essential arterial hypertension (AH). MethodsPatients aged 30-70 years with AHU and essential hypertension grade 1-2 with adequate blood pressure (BP) control, without previous urate lowering therapy (ULT) were divided into two groups: a) receiving allopurinol (ULT group) and b) age-and sex matched patients without ULT (control group). Both groups received UA-lowering diet. BP (office, 24 hour and central), echocardiographic parameters, pulse-wave velocity, carotid intima-media thickness (IMT) and lab tests (high-sensitivity C-reactive protein (hs-CRP) were measured at baseline and at 6 months follow-up.ResultsOut of 100 participants 87 completed the study (44 ULT patients and 43 controls). At 6 months follow-up, there was a significantly greater reduction in serum UA concentration in the ULT group than in the control group (464±68.8 µmol/l vs 314±55.6 µmol/l, p<0.0001). Patients receiving allopurinol had significant reductions in office systolic (137±11.8 mmHg vs 134±9.3 mmHg; p=0.025) and diastolic BP (83±9.9 mmHg vs 79±8.7 mmHg, p=0.017), central systolic BP (56±8.9 mmHg vs 51±12.9 mmHg, p=0.046), pulse pressure (43±10.4 mmHg vs 39±11.2 mmHg, p=0.017), IMT (0.773±0.121 mm vs 0.752±0.13 mm, p=0.044), left atrium volume index (40±13.5 ml/m2 vs 38±12.3 ml/m2, p=0.044), and hs-CRP level (3.36±2.73 mg/l vs 2.74±1.91 mg/l, p=0.028) compared to controls. The decrease in UA concentration was significantly related to the reduction in IMT (R=0.37, p<0.001), central SBP (R=0.26, p=0.015) and hs-CRP concentration (R=0.30, p=0.004). Multivariate regression analysis revealed the independent relationship between reduction in IMT and UA lowering (R=0.3234, R2=0.0722, p<0.026).ConclusionsIn patients with AH and asymptomatic hyperuricemia treatment with allopurinol leads to further improvement in BP control and reduction in HMOD intensity, in particular IMT. The decrease in hs-CRP concentration associated with ULT may have a beneficial effect on patient long-term prognosis.

Background: Pulmonary arterial hypertension (PAH) is a disease characterized by dyspnea, fatigue, chest pain and syncope. As there is no known cure for PAH, the goal of treatment is to control symptoms and slow disease progression. Sildenafil, a phosphodiesterase-5 inhibitor, has been indicated to improve exercise capacity in PAH in both the United States and the European Union since 2005; since 2009, it also has been indicated in the United States to delay clinical worsening. Patterns of sildenafil use in PAH patients have not been reported. Objectives: To describe patterns of treatment with sildenafil among commercially insured patients in the United States with PAH. Methods: Using a large U.S. healthcare claims database, we identified all patients with evidence of PAH (International Classification of Disease, 9th Revision, Clinical Modification [ICD-9-CM] diagnosis codes 416.0, 416.8) and receipt of sildenafil between January 1, 2005 and September 30, 2008. The date of each patient’s earliest pharmacy claim for sildenafil was designated as his or her “index date”; patients with &lt;6 months of data prior to this date were excluded. Post-index use of sildenafil was then examined in terms of the numbers of pharmacy claims and therapy-days, the medication possession ratio (MPR), and the incidence of therapy switching. Results: We identified a total of 855 PAH patients who began sildenafil therapy and met all other entry criteria. Mean (standard deviation [SD]) follow-up was 423.4 (313.0) days. Over this period, these patients averaged 7.1 (6.8) (median, 5) pharmacy dispensings for sildenafil, representing 273.4 (254.8) therapy-days (median, 180). Mean MPR was 71% (median, 83%). Fourteen percent of sildenafil patients switched to another agent during follow-up. Conclusions: In “real-world” clinical practice, many PAH patients beginning treatment with sildenafil remain on therapy for extended periods and are relatively compliant with treatment.
