Since the 1990's cabergoline has been the treatment of choice in prolactinoma, as it permits rapid and effective hormonal and tumor control in most cases. Evidence of cardiac valvulopathy was demonstrated in Parkinson's disease patients treated with dopamine agonists. Retrospective studies in prolactinoma patients treated with cabergoline at lower doses did not show such an effect. However, few prospective data with long-term follow-up are available. The aim of this study was to assess the safety of cabergoline regarding cardiac valvular status during prospective follow-up in patients treated for prolactinoma or idiopathic hyperprolactinemia. We report here a series of 100 patients (71F; median age at diagnosis: 41.5 years) treated with cabergoline for endocrine diseases (prolactinoma n = 89, idiopathic hyperprolactinemia n = 11). All patients underwent complete transthoracic echocardiographic studies at baseline and during long-term prospective surveillance using the same equipment and performed by the same technicians. The median interval between baseline and last follow-up echocardiographic studies while on cabergoline was 62.5 months (interquartile range: 34.75-77.0). The median total duration of cabergoline treatment was 124.5 months (interquartile range: 80.75-188.75) and the median cumulative total dose of cabergoline was 277.8 mg (interquartile range : 121.4-437.8 mg) at last follow-up. We found no clinically relevant alterations in cardiac valve function or valvular calcifications with cabergoline treatment. Our data suggest that findings from retrospective analyses are correct and that cabergoline is a safe chronic treatment at the doses used typically in endocrinology. [less ▲]

Prosthetic heart valve (PHV) dysfunction is rare but potentially life-threatening. Although often challenging, establishing the exact cause of PHV dysfunction is essential to determine the appropriate treatment strategy. In clinical practice, a comprehensive approach that integrates several parameters of valve morphology and function assessed with 2D/3D transthoracic and transoesophageal echocardiography is a key to appropriately detect and quantitate PHV dysfunction. Cinefluoroscopy, multidetector computed tomography, cardiac magnetic resonance imaging, and to a lesser extent, nuclear imaging are complementary tools for the diagnosis and management of PHV complications. The present document provides recommendations for the use of multimodality imaging in the assessment of PHVs. [less ▲]

AIMS: The objective assessment of maximal exercise capacity (MEC) using peak oxygen consumption (VO2) measurement may be helpful in the management of asymptomatic aortic stenosis (AS) patients. However, the relationship between left ventricular (LV) function and MEC has been relatively unexplored. We aimed to identify which echocardiographic parameters of LV systolic function can predict MEC in asymptomatic AS. METHODS AND RESULTS: Asymptomatic patients with moderate to severe AS (n = 44, aortic valve area <1.5 cm2, 66 +/- 13 years, 75% of men) and preserved LV ejection fraction (LVEF > 50%) were prospectively referred for resting echocardiography and cardiopulmonary exercise test. LV longitudinal strain (LS) of each myocardial segment was measured by speckle tracking echocardiography (STE) from the apical (aLS) 4-, 2-, and 3-chamber views. An average value of the LS of the analysable segments was provided for each myocardial region: basal (bLS), mid (mLS), and aLS. LV circumferential and radial strains were measured from short-axis views. Peak VO2 was 20.1 +/- 5.8 mL/kg/min (median 20.7 mL/kg/min; range 7.2-32.3 mL/kg/min). According to the median of peak VO2, patients with reduced MEC were significantly older (P < 0.001) and more frequently females (P = 0.05). There were significant correlations between peak VO2 and age (r = -0.44), LV end-diastolic volume (r = 0.35), LV stroke volume (r = 0.37), indexed stroke volume (r = 0.32), and E/e' ratio (r = -0.37, all P < 0.04). Parameters of AS severity and LVEF did not correlate with peak VO2 (P = NS for all). Among LV deformation parameters, bLS and mLS were significantly associated with peakVO2 (r = 0.43, P = 0.005, and r = 0.32, P = 0.04, respectively). With multivariable analysis, female gender (beta = 4.9; P = 0.008) and bLS (beta = 0.50; P = 0.03) were the only independent determinants (r2 = 0.423) of peak VO2. CONCLUSION: In asymptomatic AS, impaired LV myocardial longitudinal function determines reduced MEC. Basal LS was the only parameter of LV regional function independently associated with MEC.

BACKGROUND: The aim of this study was to determine the impact on the outcome of serial B-type natriuretic peptide (BNP) changes during follow-up in asymptomatic patients with >/= moderate aortic stenosis (AS) and preserved left ventricular ejection fraction. METHODS: We prospectively screened 69 patients who underwent comprehensive transthoracic echocardiography, BNP level measurement at baseline and after every 6 or 12 months. Annualized BNP changes were calculated as the difference between the last and baseline BNP measurements divided by the duration of follow-up. The primary endpoint was the occurrence of symptoms, aortic valve replacement, or cardiovascular death. RESULTS: During a follow-up of 30 +/- 19 months, 43 patients experienced a cardiac event. These patients were significantly older (73 +/- 9 vs 65 +/- 16 years; P = 0.010), had more often dyslipidemia (79% vs 42%; P = 0.038), more severe AS (peak velocity: 3.9 +/- 0.6 vs 3.5 +/- 0.6 m/s; P = 0.002), larger indexed left atrial area (10.2 +/- 2.5 vs 8.7 +/- 1.9 cm2/m2; P = 0.006), and a higher increase in annualized BNP (+90 +/- 155 vs +7 +/- 49 pg/mL/y; P = 0.010). Patients with higher annualized BNP changes (> 20 pg/mL/y) had a significantly lower cardiac event-free survival (1 year: 63 +/- 8% vs 97 +/- 3%; 3 years: 31 +/- 8% vs 68 +/- 8%; P < 0.001). Using the multivariate Cox proportional hazards model, higher annualized BNP changes were significantly associated with increased risk of cardiac events (hazard ratio: 2.73, 95% confidence interval: 1.27-5.86; P = 0.010) after adjustment for age, dyslipidemia, and echocardiographic parameters. CONCLUSIONS: In asymptomatic patients with AS and preserved left ventricular ejection fraction, the use of serial BNP changes may help to anticipate development of class I indication for aortic valve replacement.

AIMS: Reference values for Doppler parameters according to age and gender are recommended for the assessment of heart physiology, specifically for left ventricular (LV) diastolic function. In this study, we report normal reference ranges for Doppler parameters obtained in a large group of healthy volunteers. Echocardiographic data were acquired using state-of-the-art cardiac ultrasound equipment following Doppler acquisition and measurement protocols approved by the European Association of Cardiovascular Imaging. METHODS AND RESULTS: A total of 449 (mean age: 45.8 +/- 13.7 years) healthy volunteers (198 men and 251 women) were enrolled at the collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. A comprehensive echocardiographic examination was obtained from all subjects following predefined protocols. The majority of the Doppler diastolic parameters (e', E/e') as well as right ventricle systolic s' wave velocity were similar in men and women. Left ventricle s' wave velocity was higher in men than in women. E wave and e' were higher in younger subjects and decreased progressively in the older ones. E/e' ratio increased with ageing. Septal e' <8 cm/s was present in 19.7% of the subjects in the 40-60 year group and in 55% of those in the >/=60 year group. However, the cut-off value of average E/e' or lateral E/e' remained <15 or 13, respectively, in the majority of patients. CONCLUSION: The NORRE study provides the reference values for the most useful Doppler parameters in the evaluation of heart physiology. These data highlight the need of using age-specific reference values especially for the diagnosis of LV systolic and diastolic dysfunction and for the estimation of LV filling pressures. [less ▲]

B-type natriuretic peptide (BNP) is often used as a complementary finding in the diagnostic work-up of patients with aortic stenosis (AS). Whether soluble ST2, a new biomarker of cardiac stretch, is associated with symptomatic status and outcome in asymptomatic AS is unknown. sST2 and BNP levels were measured in 86 patients (74+/-13 years; 59 asymptomatic, 69%) with AS (<1.5 cm2) and preserved left ventricular ejection fraction who were followed-up for 26+/-16 months. Both BNP and sST2 were associated with NYHA class but sST2 (>23 ng/mL, AUC = 0.68, p<0.01) was more accurate to identify asymptomatic patients or those who developed symptoms during follow-up. sST2 was independently related to left atrial index (p<0.0001) and aortic valve area (p = 0.004; model R2 = 0.32). A modest correlation was found with BNP (r = 0.4, p<0.01). During follow-up, 29 asymptomatic patients (34%) developed heart failure symptoms. With multivariable analysis, peak aortic jet velocity (HR = 2.7, p = 0.007) and sST2 level (HR = 1.04, p = 0.03) were independent predictors of cardiovascular events. In AS, sST2 levels could provide complementary information regarding symptomatic status, new onset heart failure symptoms and outcome. It might become a promising biomarker in these patients.

BACKGROUND: Mitral regurgitation is a frequent valvular heart disease affecting around 2.5 % of the population with prevalence directly related to aging. Degeneration of mitral valve is broadly considered as a passive ongoing pathophysiological process and little is known about its physiological deregulation. The purpose of this study was to highlight new biomarkers of mitral regurgitation in order to decipher the underlying pathological mechanism as well as to allow the diagnosis and the monitoring of the disease. RESULTS: Modulation of various blood proteins expression was examined in patients suffering from different grades of mitral regurgitation (mild, moderate and severe) compared to healthy controls. To this end, several routine clinical assays and the multi analyte profile technology targeting 184 proteins were used. High-density lipoprotein, apolipoprotein-A1, haptoglobin and haptoglobin-alpha2 chain levels significantly decreased proportionally to the degree of mitral regurgitation when compared to controls. High-density lipoprotein and apolipoprotein-A1 levels were associated with effective regurgitant orifice area and regurgitant volume. Apolipoprotein-A1 was an independent predictor of severe mitral regurgitation. Moreover, with ordinal logistic regression, apolipoprotein-A1 remained the only independent factor associated with mitral regurgitation. In addition, myxomatous mitral valves were studied by immunocytochemistry. We observed an increase of LC3, the marker of autophagy, in myxomatous mitral valves compared with healthy mitral valves. CONCLUSION: These potential biomarkers of mitral regurgitation highlighted different cellular processes that could be modified in myxomatous degenerescence: reverse cholesterol transport, antioxidant properties and autophagy.

OBJECTIVES: Cardiovascular involvement is recognized as a poor prognostic factor in systemic sclerosis (SSc). The aim of this study was to evaluate the usefulness of nailfold video-capillaroscopy (NVC), brain natriuretic peptide (BNP) blood level and exercise echocardiography to predict the occurrence of cardiovascular events in SSc. METHODS: We prospectively enrolled 65 patients with SSc (age 54+/-14 years, 30% female) followed in CHU Sart-Tilman, Liege, Belgium. All patients underwent graded semi-supine exercise echocardiography. Both baseline resting pulmonary hypertension (PH) and PH during follow-up (FUPH) were defined as systolic pulmonary arterial pressure (sPAP)>35 mmHg, and exercise-induced PH (EIPH) as sPAP>50 mmHg during exercise. RESULTS: EIPH was present in 21 patients. During FU (27+/-18 months), 13 patients developed FUPH and 9 presented cardiovascular complications. Patients with cardiovascular events were significantly older (63+/-14 vs 52+/-13 years; P=0.03), presented more frequently NVC grade>2 (89 vs 43%; P=0.009), had higher resting and exercise sPAP (30+/-6 vs 24+/-6; P=0.007 and 57+/-13 vs 44+/-13 vs mmHg; P=0.01, respectively), and higher BNP blood level (112+/-106 vs 26+/-19 pg/ml; P=0.0001). After adjustment for age and gender, NVC grade>2 (ss=2.4+/-1.1; P=0.03), EIPH (ss=2.30+/-1.13; P=0.04), FUPH (ss=0.24+/-0.09; P=0.01 and ss=3.52+/-1.16; P=0.002, respectively;) and BNP (ss=0.08+/-0.04; P=0.02) were independent predictors of CV events. Beyond age, an incremental value of EIPH, BNP and NVC grade>2 was predictive of cardiovascular events (P<0.001). CONCLUSION: Cardiovascular complications are not rare in SSc (18%). NVC, BNP blood level assessment and exercise echocardiography could be useful tools to identify patients at risk of SSc. [less ▲]

BACKGROUND: Elevated resting heart rate is associated with worse outcomes in chronic heart failure (HF) but little is known about its prognostic impact in acute setting. The main aim of the present study was to examine the relationship between resting heart rate obtained 24-36h after admission for acute non-arrhythmic HF and in-hospital mortality. METHODS AND RESULTS: We examined the association of heart rate with in-hospital mortality in a cohort of 712 patients admitted for acute HF. None of the patients had significant arrhythmias, required invasive ventilation, or presented with acute coronary syndrome or primary valvular disease. Forty patients (5.6%) died during the hospital stay. Those patients were significantly older (78+/-9 vs. 72+/-12years; p=0.0021), had higher heart rate (92+/-22 vs. 78+/-18bpm; p<0.0001), NT pro-BNP (p=0.0005), creatinine (p=0.023), were often diabetics (p=0.026) and had lower systolic and diastolic blood pressures (p<0.05). There was a significant graded relationship between the increase in mortality rate and tertile of heart rate (p<0.01). With multivariable analysis, age (p=0.037), heart rate (p<0.0001), diastolic blood pressure (p<0.001), prior ischemic heart disease (p=0.02) and creatinine (p=0.019) emerged as independent predictors of in-hospital mortality. After adjusting for predictors of poor prognosis, patients in the highest heart rate tertile had worst outcomes when compared with those in the lowest heart rate group (p=0.007). CONCLUSIONS: Higher heart rate 24-36h after admission for acute non-arrhythmic HF is associated with increased risk of in-hospital mortality. Early targeting of elevated heart rate might represent a complementary therapeutic challenge. [less ▲]

In patients with heart failure, exercise echocardiography can help in risk stratification and decision making. The prognostic significance of exercise pulmonary hypertension (PH) in patients with secondary mitral regurgitation (MR) remains unknown. The aim of the present study was to assess the prognostic value of exercise PH in patients with secondary MR and narrow QRS intervals. From 2005 to 2012, 159 consecutive patients with secondary MR, narrow QRS intervals, left ventricular dysfunction (mean ejection fraction 36 +/- 7%), and measurable systolic pulmonary arterial pressure (SPAP) during exercise echocardiography were included. Resting and exercise PH were defined as SPAP >50 and >60 mm Hg, respectively. Exercise PH was more frequent than resting PH (40% vs 13%, p <0.0001). On multivariate logistic regression, the independent determinants of exercise PH were resting SPAP (p <0.0001), exercise MR severity (p <0.0001), and e'-wave velocity (p = 0.004). The incidence of cardiac events during follow-up was significantly higher in patients with exercise PH compared with those without exercise PH (4 years: 40 +/- 7% vs 20 +/- 5%, p <0.0001). Patients with exercise PH exhibited higher rates of cardiac events and death than those with resting PH. In a multivariate Cox proportional hazards model, exercise PH was independently associated with the occurrence of cardiac events (p <0.0001). In conclusion, in patients with secondary MR, exercise PH is determined mainly by resting SPAP, left ventricular diastolic burden, and exercise MR severity. Exercise PH is a powerful predictor of poor outcomes, with a 5.3-fold increased risk for cardiac-related death during follow-up. These results highlight the added value of exercise echocardiography in secondary MR. [less ▲]

Pulmonary hypertension (PH) is a classic pathophysiological consequence of left-sided valvular heart disease (VHD). However, as opposed to other forms of PH, there are relatively few published data on the prevalence, impact on outcome, and management of PH with VHD. The objective of this paper is to present a systematic review of PH in patients with VHD. PH is found in 15% to 60% of patients with VHD and is more frequent among symptomatic patients. PH is associated with higher risk of cardiac events under conservative management, during valve replacement or repair procedures, and even following successful corrective procedures. In addition to its usefulness in assessing the presence and severity of VHD, Doppler echocardiography is a key tool in diagnosis of PH and assessment of its repercussion on right ventricular function. Assessment of pulmonary arterial pressure during exercise stress echocardiography may provide additional prognostic information beyond resting evaluation. Cardiac magnetic resonance is also useful for assessing right ventricular geometry and function, which provide additional prognostic information in patients with VHD and PH. [less ▲]
