Perceptions of cardiology, professional preferences and impact on career choices among Portuguese cardiologists: Results from the Portuguese Society of Cardiology's Women and Cardiology Task Force survey.

INTRODUCTION AND OBJECTIVES: Cardiology has not been seen as an attractive specialty, and women have avoided it for many years. Some surveys have been performed in other countries, but in Portugal, the situation is largely unknown. METHODS: An online survey on perceptions of cardiology and professional preferences was sent to 1371 members of the Portuguese Society of Cardiology, of whom 18.2% completed the survey. RESULTS: We included 219 cardiologists or cardiology trainees, of whom 50.2% were female, with decreasing proportions from younger to older age groups, in which males still predominate. Women are less often married and more frequently childless, particularly those working in an invasive subspecialty, where they represent only 16% of all respondents working in these areas. Men's perception is that women do not choose these areas due to family reasons, radiation concerns and difficult working conditions, but from the female perspective, male dominance, lack of female role models and restricted access are the main barriers. Women consider it is difficult for them to obtain a leadership role, but men do not think the same (75.5% vs. 27.5%). CONCLUSION: In Portugal, females predominate in younger age groups, suggesting a paradigm change. Women are less frequently married and more frequently childless, particularly women working in invasive subspecialties. Women consider that it is more difficult for them to obtain a leadership role. Moreover, the barriers reported by women are substantially different from men regarding the reasons for not choosing an invasive subspecialty.

Levosimendan in outpatients with advanced heart failure: Single-center experience of 200 intermittent perfusions.

INTRODUCTION: Patients with advanced heart failure (HF) have high morbidity and mortality, with only a small proportion being eligible for advanced therapies. Intermittent outpatient levosimendan infusion has been shown to provide symptomatic relief and reduce the rate of HF events. Our aim was to assess the safety and efficacy of outpatient levosimendan administration in an advanced HF population. METHODS: This is a report of a single-center experience of consecutive advanced HF patients referred for intermittent intravenous outpatient administration of levosimendan, between January 2018 and March 2021. Baseline and follow-up evaluation included clinical assessment, laboratory tests, transthoracic echocardiography and cardiopulmonary exercise testing. Baseline and clinical follow-up data were compared using the Wilcoxon signed-rank test. RESULTS: A total of 24 patients (60.8 years, 83% male, mean left ventricular ejection fraction [LVEF] 24%), with a median of 1.5 HF hospitalizations in the previous six months, were referred for outpatient levosimendan pulses, the majority as a bridge to transplantation or due to clinical deterioration. At six-month follow-up there was a significant reduction in HF hospitalizations to 0.4±0.7 (p<0.001). NYHA class IV (52.2% to 12.5%, p=0.025) and NT-proBNP (8812.5 to 3807.4 pg/ml, p=0.038) were also significantly reduced. Exercise capacity was significantly improved, including peak oxygen uptake (p=0.043) and VE/VCO2 slope (p=0.040). LVEF improved from 24.0% to 29.7% (p=0.008). No serious adverse events were reported. CONCLUSION: Repeated levosimendan administration in advanced HF patients is a safe procedure and was associated with a reduction in HF hospitalizations, functional and LVEF improvement, and reduction in NT-proBNP levels during follow-up.

C-reactive protein reduction with sacubitril-valsartan treatment in heart failure patients.

OBJECTIVE: C-Reactive Protein (CRP) has emerged as an accessible measured product of inflammation. Whether systemic inflammation, a common feature of Heart Failure (HF), can be reduced by HF treatments in not well established. Sacubitril/Valsartan had prognosis benefit demonstrated in the PARADIGM-HF trial and was able to reduce proinflammatory cytokines in preclinical animal studies. However, no human studies evaluated if the benefits of this therapy are mediated by anti-inflammatory effects too. The aim of this study was to prospectively compare CRP values before and six months after Sacubitril-Valsartan therapy. METHODS: Prospective evaluation of chronic HF patients with left ventricular ejection fraction ≤ 40% despite optimized standard of care therapy, in which Sacubitril/Valsartan therapy was started and no additional HF treatment was expected to change. Clinical, laboratorial (including CRP values), electrocardiographic, transthoracic echocardiography and cardiopulmonary exercise test (CPET) data were gathered in the week before starting Sacubitril/Valsartan therapy and six months thereafter. RESULTS: There were 42 patients with a mean age of 59 ± 11 years, of which 35 completed the six months of follow-up, since 2 patients died and 5 discontinued treatment for adverse events. Patients with baseline CRP values above the median (> 2.5 mg/L) had a significantly higher percentage of New York Heart Association class ≥ III (65% vs. 33%, P=0.028) and a reduced exercise time in CPET (361 ± 297 vs. 575 ± 265 seconds, P=0.034). After 6 months of Sacubitril-Valsartan therapy, 24 (69%) patients had an improvement in CRP values with a significantly reduction as compared to baseline (median 2.5 mg/L (Interquartile range (IQR) 1.3-5.0) vs. 2.2 mg/L (IQR 0.9-4.0), P=0.014 in the Wilcoxon test). In the group of 17 (49%) patients with at least 25% improvement in CRP values with Sacubitril/Valsartan therapy, the benefit of several clinical, CPET and echocardiographic parameters were not significantly different from the benefit of patients with no improvement or an improvement inferior to 25% in CRP values. CONCLUSION: Sacubitril/Valsartan therapy was able to reduce CRP values in a chronic HF population. Whether this reduction was only a consequence of clinical improvement with Sacubitril/Valsartan or an anti-inflammatory effect is also present should be further evaluated.

Three-dimensional speckle-tracking echocardiography for the global and regional assessments of left ventricle myocardial deformation in breast cancer patients treated with anthracyclines.

BACKGROUND: Assessment of 2D/3D left ventricular ejection fraction (LVEF) and 2D global longitudinal strain (GLS) is the gold standard for diagnosing cancer therapeutics-related cardiac dysfunction (CTRCD). Although 3D speckle-tracking echocardiography (STE) has several advantages, it is not used in this setting. METHODS: 105 breast cancer patients who underwent serial echocardiographic assessment during anthracycline therapy were included. STE was used to estimate 2D GLS, 3D GLS, 3D global circumferential strain (GCS), 3D global radial strain (GRS), and 3D global area strain (GAS). CTRCD was defined as an absolute decrease in 2D/3D LVEF > 10% to a value < 54% or a relative decrease in 2D GLS > 15%. RESULTS: 24 patients developed CTRCD. There was a significant worsening of all 3D strain parameters during chemotherapy. 3D strain regional analysis showed impaired contractility in the anterior, inferior, and septal walls. Variations of 3D GRS and 3D GCS were associated with a higher incidence of CTRCD and the variation of 3D GRS was an independent predictor of CTRCD. Variations of 3D GCS and 3D GRS had a good discrimination for predicting CTRCD, with optimal cutoff values of - 34.2% for 3D GCS and - 34.4% for 3D GRS. These variations were observed 45 and 23 days before the diagnosis of CTRCD, respectively. CONCLUSION: Variations of 3D strain parameters were predictive of and preceded CTRCD, and thus have added value over currently recommended 2D/3D LVEF and 2D GLS. Routine application of this technique should be considered to offer targeted monitoring and timely initiation of cardioprotective treatment.

Antiarrhythmic Effect of Sacubitril-Valsartan: Cause or Consequence of Clinical Improvement?

Sacubitril/Valsartan (LCZ696) reduced sudden cardiac death in the PARADIGM-HF trial. However, the mechanism by which LCZ696 reduces ventricular arrhythmias remains unclear. The aim of this study was to compare electrocardiographic (ECG) parameters and mechanical dispersion index, assessed by left ventricular (LV) global longitudinal strain (GLS), before and after LCZ696 therapy. We prospectively evaluated chronic Heart Failure (HF) patients with LV ejection fraction ≤40%, despite optimal medical and device therapy, in which LCZ696 therapy was started, while no additional HF treatment was expected to change. ECG and transthoracic echocardiographic data were gathered in the week before starting LCZ696 and at six months of therapy. A semiautomated analysis of LV GLS was performed and mechanical dispersion index was defined as the standard deviation from 16 time intervals corresponding to each LV segment. Of the 42 patients, 35 completed the six month follow-up, since two patients died and five discontinued treatment for adverse events. QTc interval (451.9 vs. 426.0 ms, p < 0.001), QRS duration (125.1 vs. 120.8 ms, p = 0.033) and mechanical dispersion index (88.4 vs. 78.1 ms, p = 0.036) were significantly reduced at six months. LCZ696 therapy is associated with a reduction in QTc interval, QRS duration and mechanical dispersion index as assessed by LV GLS.

The smoker's paradox in acute coronary syndrome: Is it real?

INTRODUCTION: Smoking is associated with atherosclerotic disease, but there is controversy about its protective nature after acute coronary syndrome (ACS). OBJECTIVE: To determine the impact of smoking on the presentation, treatment and outcome of ACS. METHODS: We analyzed all consecutive patients with ACS in a single center between 2005 and 2014. Current smokers and never-smokers were compared. Independent predictors of in-hospital mortality and of a composite of all-cause mortality, rehospitalization for cardiovascular causes, angiography, percutaneous coronary intervention and coronary artery bypass grafting were assessed by multivariate logistic regression. RESULTS: A total of 2727 patients were included, 41.7% current smokers and 58.3% never-smokers. Current smokers were younger, more often male, had fewer comorbidities, a typical clinical presentation, lower heart rate, systolic blood pressure, Killip class, BNP/NT-pro-BNP and creatinine, better left ventricular systolic function and less severe coronary anatomy. ST-segment elevation myocardial infarction was more common in current smokers. Current smokers received more evidence-based treatments and had less in-hospital complications, in-hospital mortality and adverse outcomes at one year. More frequent percutaneous coronary intervention at one year was noted in current smokers. Smoking was not an independent predictor of outcome when the multivariate model was fully adjusted for baseline characteristics. CONCLUSION: The smoker's paradox was not observed in this population, since all differences in outcome were explained by smokers' more benign baseline characteristics.

Infective endocarditis: Surgical management and prognostic predictors.

INTRODUCTION AND AIM: Infective endocarditis (IE) is associated with high morbidity and mortality. It is important to determine which factors increase the risk of poor outcome in order to enable early detection and aggressive treatment, including surgery. The aim of our study was to identify factors predicting complications and in-hospital mortality in patients with IE and to analyze conditions predisposing to surgery and its outcome. METHODS: We performed a retrospective study including patients with IE who underwent transesophageal echocardiography in a tertiary hospital center (2006-2014). RESULTS: A total of 233 patients were analyzed (69.1% male; mean age 63.4±15.2 years; mean follow-up 28.4±30.7 months). The complication rate was 56.6% and in-hospital mortality was 16.3%. Independent predictors of mortality were chronic obstructive pulmonary disease (OR 4.89; CI 1.36-17.63; p=0.015), clinical course complicated by cerebral embolism (OR 9.38; CI 3.26-26.96; p<0.001), and IE due to Staphylococcus spp. (OR 3.78; CI 1.32-10.85; p=0.014) and non-HACEK Gram-negative bacilli (OR 12.85; CI 2.61-63.23; p=0.002). Surgery was performed in 36.9%. This group had higher percentages of males, younger patients, aortic valve IE, large vegetations, perivalvular extension, severe valvular regurgitation and heart failure. In patients with surgical indication (n=133), those who underwent surgery had lower in-hospital mortality (15.5% vs. 32.6%, p=0.028) and better long-term survival (log-rank p=0.029). CONCLUSION: The results of this study may help to identify IE patients who are at increased risk of worse outcome, offering the opportunity to change the course of the disease and to improve prognosis with earlier and more aggressive intervention.
