Do Women Physicians Accept and Follow Heart Failure Guidelines More Than Men?

PURPOSE OF REVIEW: Our aim was to assess the degree of acceptance of the European Clinical Practice Guidelines (CPG) on heart failure (HF) among Spanish physicians according to sex. This was a cross-sectional study, employing Google Forms, conducted by a group of HF experts from the Region of Madrid (Spain), between November 2021 and February 2022, among specialists and residents of Cardiology, Internal Medicine, and Primary Care from Spain. RECENT FINDINGS: A total of 387 physicians-173 women (44.7%)-from 128 different centers completed the survey. Compared to men, women were significantly younger (38.2 ± 9.1 years vs. 40.6 ± 11.2 years; p = 0.024) and had fewer years of clinical practice (12.1 ± 8.1 years vs. 14.5 ± 10.7 years; p = 0.014). Briefly, women and men had a positive opinion of the guidelines and thought that implementing quadruple therapy is feasible in less than 8 weeks. Women followed more frequently than men the new paradigm of "4 pillars at lowest doses" and considered more frequently the establishment of quadruple therapy before implanting a cardiac device. Although they agreed about "low blood pressure" as the major limitation for achieving quadruple therapy in heart failure with reduced ejection fraction, there were discrepancies on the second most frequent barrier, and women were more proactive when initiating SGLT2 inhibitors. In a large survey including nearly 400 doctors from all over Spain to provide real-world opinion on 2021 ESC HF Guidelines and experience with SGLT2 inhibitors, women follow more frequently the new paradigm of "4 pillars at lowest doses", consider more frequently the establishment of quadruple therapy before implanting a cardiac device, and were more proactive when initiating SGLT2 inhibitors. Further studies confirming an association of sex with a better compliance of HF guidelines are needed.

Utility of pulmonary echography with a handheld ultrasound device in patients with acute coronary syndrome.

The objectives of this study are to establish the usefulness of lung ultrasound with a handheld device to predict the risk of developing heart failure with the need for mechanical ventilation (MV) in acute coronary syndrome (ACS). This is a prospective study of consecutive patients admitted because of ACS-type myocardial infarction, without data of HF at admission in a tertiary hospital, between February 2017 and February 2018. Lung ultrasounds were performed with a handheld cardiologic device in the first 24 h, and defined as echo-positive (PE+) when exams revealed 3 or more B-lines in 2 or more bilateral quadrants. We related this finding to the need for MV during admission. We included 119 patients (65.1 ± 12.8 year; 75.6% male, 24.4% female; 87.4% in Killip class I, 12.6% in Killip class II). Pulmonary echography was positive (PE+) in 21 patients (17.6%). The sensitivity of PE+ to predict MV was 93.3%, the specificity 93.3%, and the area under the curve 0.93. In Cox regression analysis adjusted by CRUSADE score and Killip class, PE+ patients had a hazard ratio of 64.55 (CI 7.87; 529.25, p < 0.001) of needing MV. PE+ was associated with more frequent use of inotropes and mortality. Pulmonary ultrasonography with a handheld echocardiograph was predictive of severe heart failure and the need for mechanical ventilation in ACS with high specificity and sensitivity.

The role of cardiopulmonary exercise testing in identifying and monitoring pulmonary veno-oclusive disease: a case report with ING.

Background: Pulmonary veno-occlusive disease (PVOD) is a subgroup of pulmonary arterial hypertension (PAH) where vascular remodelling affects mainly the post-capillary vessels. It is characterized by a particularly worse prognosis and by the risk of developing life-threatening pulmonary oedema, especially after PAH-targeted therapy. Therefore, suspicion of PVOD is crucial to guide the patient's management. In the absence of specific genetic or histological findings, diagnosis has traditionally relied on the recognition of non-invasive indicators associated with a high likelihood of PVOD. The cardiopulmonary exercise testing (CPET) arises as a promising additional tool both to identify these patients and to guide their management. Case summary: We report the case of a young female patient with dyspnoea and clinical suspicion of PVOD. The diagnostic workup is thoroughly described stressing the valuable and readily accessible information that CPET can provide, in addition to the data of radiological and lung function tests. Once diagnosed, she was started on PAH-targeted therapy with subsequent improvement. The patient underwent a complete reassessment with satisfactory findings, including those of the CPET. Discussion: Pulmonary veno-occlusive disease diagnosis is still one of the most difficult tasks that pulmonary hypertension physicians have to deal with. An accurate and timely PVOD diagnosis can be challenging, as it is to decide the most appropriate timing of referal to the lung transplant team, and CPET may serve these purposes. Through this case, we would like to review one of the typical clinical courses that PVOD may present and how to analyse the information provided by the diagnostic tests.

The impact of COVID-19 pandemic on pulmonary hypertension: What have we learned?

The coronavirus 2019 disease (COVID-19) pandemic threatened the Spanish health-care system. Patients with demanding conditions such as precapillary pulmonary hypertension (PH) faced a potentially severe infection, while their usual access to medical care was restricted. This prospective, unicentric study assessed the impact of COVID-19 on PH patients' outcomes and the operational changes in the PH network. Sixty-three PH patients (41 pulmonary arterial hypertension [PAH]; 22 chronic thromboembolic pulmonary hypertension [CTEPH]) experienced COVID-19. Overall mortality was 9.5% without differences when stratifying by hemodynamics or PAH-risk score. Patients who died were older (73.6 ± 5 vs. 52.2 ± 15.4; p = 0.001), with more comorbidities (higher Charlson index: 4.17 ± 2.48 vs. 1.14 ± 1.67; p = 0.0002). Referrals to the PH expert center decreased compared to the previous 3 years (123 vs. 160; p = 0.002). The outpatient activity shifted toward greater use of telemedicine. Balloon pulmonary angioplasty activity could be maintained after the first pandemic wave and lockdown while pulmonary thromboendarterectomy procedures decreased (19 vs. 36; p = 0.017). Pulmonary transplantation activity remained similar. The COVID-19 mortality in PAH/CTEPH patients was not related to hemodynamic severity or risk stratification, but to comorbidities. The pandemic imposed structural changes but a planned organization and resource reallocation made it possible to maintain PH patients' care.

Epoprostenol for the treatment of pulmonary arterial hypertension.

Introduction: Pulmonary arterial hypertension (PAH) is a rare, progressive, and severe disease. Since the first demonstration of survival benefit of intravenous epoprostenol in monotherapy in 1996, prostanoids remain the cornerstone for PAH patients at high risk. This review is essential to understand the current situation of this drug among all the therapeutic possibilities concerning this entity.Areas covered: The aim of this article is to review the pharmacological properties of epoprostenol and to update its clinical evidence in different specific clinical scenarios. A deep literature search was carried out on the MEDLINE database for published literature before March 2021.Expert opinion: Epoprostenol is still the best treatment option for high-risk PAH patients. Nevertheless, there are many unsolved questions: drug dosing, its use in combination therapy with other pulmonary vasodilators, and the utility in PAH associated with connective tissue disease, congenital heart disease, or pulmonary veno-occlusive disease are only a few examples. Its safety and efficacy are supported by clinical trials, observational work, and experience, both as monotherapy and in combination therapy. Epoprostenol should be considered a destination treatment in high-risk patients and not only as a bridge to pulmonary transplantation. However, it remains underused in clinical practice.

Complications associated with peripherally inserted central catheters and Hickman™ in patients with advanced pulmonary hypertension treated with intravenous prostanoids.

BACKGROUND: Epoprostenol requires continuous infusion and may lead to catheter-related complications. Evidence regarding the comparison between peripherally inserted central catheters (PICC) or tunneled central catheters in Pulmonary Hypertension (PH) is scarce. We sought to study the incidence of mechanical and infectious complications associated with PICC and Hickman catheters in patients with PH under epoprostenol treatment. METHODS: This is a single-center retrospective study of patients with PH who received continuous treatment with intravenous epoprostenol for at least 24 h between January 2010 and July 2020. Mechanical and infectious complications were analyzed according to the catheter type: PICC and Hickman. The incidence of catheter-related complications was calculated per 1000 exposure-days of risk. RESULTS: 175 catheters were implanted in 109 patients, of which 100 (57.1%) were Hickman and 75 (42.9%) were PICC. After a median follow-up of 334 [130-798] days, there were no differences in the rates of local (0.22 vs 0.21; p = 0.904) or blood-stream infections (0.13 vs 0.21; p = 0.405). Mechanical complications were more frequent in the PICC group (0.98 vs 0.23 p=<0.001), including venous thrombosis (0.16 vs 0.00 p = 0.003) and catheter occlusion (0.66 vs 0.04 p=<0.001). These complications were associated with a greater need for hospitalization (1.48 vs 0.50; p=<0.001), without differences in mortality during follow-up (0.33 vs 0.21; p = 0.288). CONCLUSION: In patients with PH treated with intravenous epoprostenol, both Hickman and PICC catheters were associated with high rate of complications. Although there were no differences in the frequency of infectious-related complications, PICC was associated with a higher frequency of catheter occlusion and deep venous thrombosis.

Sex Differences in Chronic Thromboembolic Pulmonary Hypertension. Treatment Options over Time in a National Referral Center.

(1) Background: Clinical presentation, disease distribution, or treatment received may provide insights into the reasons contributing to sex differences in chronic thromboembolic pulmonary hypertension (CTEPH). (2) Methods: We evaluated 453 patients (56% women) between 2007-2019. Data was collected from REHAP (Registro Español de Hipertensión Arterial Pulmonar) registry. Two time periods were selected to evaluate the influence of new treatments over time. (3) Results: Women were older. Baseline functional class was worse, and distance walked shorter in women compared with men. Women had higher pulmonary vascular resistances. Despite this, pulmonary endarterectomy (PEA) was carried out in more men, and women received more frequently pulmonary vasodilators exclusively. The 2014-2019 interval was associated with a better survival only among women. Interestingly, women had a more distal disease during this second period of time. (4) Conclusions: Even though women were older, and received invasive treatments less frequently, mortality was similar in both sexes. The introduction of balloon pulmonary angioplasty and the improvement of pulmonary endarterectomy, especially during the last years, could be associated with a survival benefit among women.
