Abstract Background Few prospective studies have evaluated sex-specific pattern, natural progression of left ventricular (LV) remodeling and diastolic dysfunction in patients with type 2 diabetes (T2DM). Purpose The aim of this study was to study the sex-specific prevalence, longitudinal changes of LV remodeling and diastolic dysfunction in patients with T2DM. Further the prognostic value of diastolic function in women and men was also evaluated. Methods A total of 386 patients with T2DM (mean age 61±11 years; women, 48.2%) was recruited. Detailed echocardiography was performed and LV geometry, systolic and diastolic function were measured at baseline and follow-up. A major adverse cardiovascular event (MACE) was defined as cardiovascular death, heart failure hospitalization or myocardial infarction. Multivariable cox-regression adjusted for age, hypertension, LVEF and HbA1c was used to assess the association between sex-specific diastolic function and the development of a MACE. Results Despite a similar age, prevalence of hypertension and body mass index, women had a higher prevalence of LV hypertrophy and diastolic dysfunction at baseline and follow-up compared with men. A total of 26 patients developed a MACE (4 cardiovascular death, 14 hospitalization for heart failure, 8 myocardial infarction) during follow-up. Women with diastolic dysfunction had a higher incidence of MACE than those with normal diastolic function but this association was neutral in men. Multivariable Cox-regression analysis indicated that diastolic dysfunction was associated with MACE in women (hazard ratio 6.35, 95% confidence interval 1.18–34.19, P<0.05) but not men (hazard ratio 1.85, 95% confidence interval 0.58–5.92, P=0.30). Conclusions LV hypertrophy and diastolic dysfunction, both at baseline and follow-up, were more common in women than men. Pre-clinical diastolic dysfunction was independently associated with MACE only in women with T2DM but was neutral in men.

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&lt;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&lt;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&lt;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.

Rv Function

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.
