Pathway to care, treatment and disease burden of pulmonary arterial hypertension: a real-world survey of physicians and patients in Latin America.

Objectives: To investigate clinical characteristics, symptom profile, testing practices, treatment patterns and quality of life (QoL) among patients with pulmonary arterial hypertension (PAH) in Latin America.

Design: Data from the Adelphi Real World PAH Disease Specific Programme, a cross-sectional survey with retrospective data collection.

Setting: University/teaching hospital, regional centres, private practices and government institutions in Argentina, Brazil, Colombia and Mexico.

Stroke risk after transcatheter aortic valve replacement in patients with carotid stenosis: A systematic review and meta-analysis.

Background: Stroke is a feared complication of transcatheter aortic valve replacement (TAVR). Patients undergoing TAVR typically have multiple comorbidities, such as carotid artery stenosis (CAS). We conducted the present meta-analysis to determine the risk of stroke and mortality following TAVR in patients with CAS.

[Gender perspective in the care experience and in the results of patients who consult for chest pain in an emergency department].

Objective: Clinical practice guidelines suggest performing an electrocardiogram (EKG) in patients with chest pain within the first 10 minutes in the emergency department, warning about subdiagnosis in women. Possible differences based on sex were analyzed.

Method: An observational and retrospective study in an Emergency Department, with adult patients admitted to the Chest Pain Unit in 2021.

Incidence of endoleak type IA in patients undergoing chimney endovascular aortic repair (ChEVAR) vs. standard endovascular repair.

Objectives: Almost half of endovascular aortic aneurysm repair (EVAR) procedures are performed in hostile anatomy, increasing the risk of procedure related complications such as type IA endoleaks, which may be prevented with the chimney technique in EVAR (ChEVAR). Our aim is to describe the differential characteristics between EVAR in favorable anatomy and ChEVAR in hostile necks.

Materials And Methods: A cohort of patients with infrarenal abdominal aortic aneurysms (AAA) that were treated with EVAR or ChEVAR were included.

Comparison of clinical outcomes of venous thromboembolic disease between outpatient and inpatient management.

Objectives: To compare the occurrence of death, bleeding, and recurrence according to inpatient or outpatient management of venous thromboembolic disease (VTE).

Materials And Methods: . Retrospective cohort that included a consecutive sampling of VTE consultations between 2016 and 2019 diagnosed in the Emergency Center of a private hospital in Argentina.

Prognostic relevance of female gender on mortality after peripheral artery disease revascularization.

Introduction: Lower limb peripheral artery disease (PAD) presents high morbidity and mortality. Women represent a small subgroup in different studies, with scarce evidence regarding the prognosis of this gender on PAD. The aim of the present work was to determine the prognostic impact of female gender on lower limb PAD revascularization.

[Clinical characteristics and care times in a chest pain unit of the emergency department of an argentine center].

Objectives: . To report the frequency of precordial pain, describe clinical characteristics, and care times.

Methods: .

[Procedural and long-term outcomes of elective endovascular abdominal aortic aneurysm repair in octogenarians].

Objective: The aim of the study was to compare the immediate and long-term outcomes of endovascular aneurysm repair (EVAR) between patients under and over the age of 80 with abdominal aortic aneurysm (AAA).

Methods: From 2011 to 2017, we conducted a retrospective cohort study with AAA patients who received elective EVAR. Primary outcomes included hospital mortality, length of stay, acute kidney injury, and the need for re-interventions.

Clinical impact of the infrapatellar location in symptomatic peripheral arterial disease patients.

Background: Peripheral artery disease (PAD) frequently affects multiple segments of the limbs. Contradictory data have reported worse prognosis in aortoiliac lesions, nevertheless, diabetes and chronic limb ischemia frequently affects the infrapatellar territory. Our aim was to assess the impact of infrapatellar disease in cardiovascular outcomes.

Population attitude and access to the healthcare system during the COVID-19 pandemic.

The COVID-19 pandemic elicited important changes in community habits and behaviors, including a distancing of people from the healthcare system. The objective of this work was to understand the causes that gave rise to changes in behavior from an individual perspective in the Argentine Republic. We performed a cross-sectional, web-based survey using an online questionnaire.

Neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio predict in-hospital mortality in symptomatic but unruptured abdominal aortic aneurysm patients.

Background: Symptomatic but unruptured abdominal aortic aneurysm (AAA) is a potentially fatal disease since its etiopathogenesis, involving acute changes in the aortic wall, including inflammation, increasing the probability of impending rupture. The objective of the present study was to assess the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) in patients undergoing urgent symptomatic AAA repair.

Methods: This was a retrospective study including 29 patients with symptomatic AAA repaired between 2011 and 2020.

[Five-year outcomes of elective infrarenal abdominal aortic aneurysm repair at a university hospital in Argentina].

Objective: Few data about outcomes of elective infrarenal abdominal aortic aneurysm (AAA) repair in Latin America have been published. The objective of the present study is to address this aspect in our population.

Method: Retrospective cohort, in which patients with infrarenal AAA undergoing elective surgical or endovascular repair from January 2011 to May 2017 at a university hospital in Autonomous City of Buenos Aires were consecutively included.

Distribution and prognostic value of high-sensitive troponin T measurement in patients with type 2 diabetes without cardiovascular disease.

Aim: The objective of this work was to define a value for the 99th percentile of high-sensitive troponin T and to evaluate the prognostic value of this biomarker in a population of patients with type 2 diabetes without a history of cardiovascular disease.

Methods: In this prospective, observational and analytic study, 482 patients with type 2 diabetes were enrolled. The patients were asymptomatic, with no history of cardiovascular events, renal insufficiency, or inflammatory or systemic disease.

Prognosis of patients with acute pulmonary embolism and discordant right ventricle strain serum biomarkers.

Background: Right ventricle strain serum biomarkers, such as high-sensitivity cardiac troponin T (hs-cTnT) and NT-pro-brain natriuretic peptide (NT-proBNP), are prognostic in patients with pulmonary embolism (PE). Prognosis accuracy in patients with discordancy between serum biomarkers remains, however, unknown.

Methods: We performed a retrospective analysis in patients with intermediate or high risk PE and discordant serum biomarkers of RV strain as follows: high hs-cTnT and low NT-proBNP ('high troponin discordance'), compared to patients with low hs-cTnT and high NT-proBNP ('high NT-proBNP discordance').

[Single center retrospective study of catheter directed thrombolysis in patients with acute pulmonary embolism].

We performed a single center retrospective study in patients wi th pulmonary embolism (PE) undergoing catheter directed thrombolysis (CDT) from 2014 to 2020. Efficacy was defined by mean pulmonary pressure drop, and safety was assessed by intracranial and severe bleeding (defined by GUSTO). Forty-three patients were included, aged 64 (56-79) years old, 5 (12%) with shock, most with right ventricle dilation (95%) and bilateral PE (95%) or unilateral (5%) in patients with only one functional lung.

Additive prognosis of clinical presentation in revascularized peripheral arterial disease patients.

Background: Peripheral artery disease (PAD) is a frequent cause of morbidity and mortality. It may present with diverse clinical presentations. The aim of this study was to evaluate the prognosis of these clinical presentations.

Distribution and prognostic value of high-sensitive troponin T measurement in patients with type 2 diabetes without cardiovascular disease.
