RESUMO
Acute pulmonary embolism (APE) is one of the leading causes of cardiovascular emergencies and the third leading cause of death. Although efforts focus on treating the acute event, patients who survive APE may develop long-term sequelae. Research reveals that approximately half of patients who have suffered an APE do not regain their previous level of function and experience a reduction in their quality of life for several years after the episode. Acute pulmonary embolism can be classified according to the risk of short-term mortality, with most mortality and morbidity concentrated in high-risk and intermediate-risk cases. The first-line treatment for APE is systemic anticoagulation. However, identifying and more aggressively treating people with intermediate to high risk, who have a more favorable risk profile for reperfusion treatments, could reduce short-term mortality and mitigate post-pulmonary embolism syndrome (PPES). Post-pulmonary embolism syndrome refers to a variety of persistent symptoms and functional limitations that occur after an APE. The presence of persistent dyspnea, functional limitations, and/or decreased quality of life after an APE has been recently termed "PPES," although this entity encompasses different manifestations. The most severe cause of persistent dyspnea is chronic thromboembolic pulmonary hypertension, where increased pulmonary artery pressure is due to the fibrotic organization of unresolved APE. Post-PE Syndrome is not always systematically addressed in management guidelines, and its prevalence may be underestimated. More research is needed to fully understand its causes and risk factors. Interventions such as cardiopulmonary rehabilitation have been suggested to improve the quality of life of patients with PPES. A comprehensive, evidence-based approach is essential to effectively prevent and manage PPES and improve the long-term outcomes and well-being of affected patients.

Hypothyroidism has been shown to have several effects on organs, including derangements in the coagulation system, impairing endothelial function, but data on the importance of hypothyroidism in the pathogenesis and development of chronic thromboembolic pulmonary hypertension (CTEPH) are limited. This report presents an updated review of the prevalence and prognosis of hypothyroidism in patients diagnosed with CTEPH, including a detailed retrospective description of the series. The descriptive case series included 34 adult patients diagnosed with CTEPH, of whom 11 patients were diagnosed with hypothyroidism. The prevalence of hypothyroidism in CTEPH was found to be 32.35%. All patients with hypothyroidism had NYHA functional Class II-III. Hemodynamic values obtained through right heart catheterization (RHC) showed that patients with hypothyroidism had significantly higher mean pulmonary arterial pressures (mPAP), with a mean of 56.91 mm Hg vs 43.93 mm Hg (pâ¯=â¯0.026), and the PVR in dynes/sec/cm5 was 932 vs 541 (pâ¯=â¯0.027). Significant differences in PVR were found in wood units (WU) 11.91 vs 7.11 (pâ¯=â¯0.042). The mean level of brain natriuretic peptide (BNP) between both groups was 797.3 pg/mL for patients with hypothyroidism vs 262.02 pg/mL in patients with euthyroidism (pâ¯=â¯.032). Hypothyroidism may significantly affect patients' clinical and hemodynamic outcomes in patients with CTEPH. Hypothyroidism as a risk factor in the evaluation and treatment of these patients is vital to optimize outcomes in CTEPH; further research is warranted whether hypothyroidism therapies could alter such outcomes.

Pulmonary hypertension (PH) is defined as an increase in mean pulmonary arterial pressure (mPAP) ≥20 mm Hg at rest as assessed by right cardiac catheterization. It has a median survival nowadays of 6 years, compared to 2.8 years in the 1980s. A pulmonary artery aneurysm (PAA) is the focal dilation of a blood vessel involving all 3 layers of the vessel wall; they have a diameter greater than 4 cm measured in the trunk of the pulmonary artery. PAAs can be classified into proximal (or central) and peripheral. The clinical manifestations of PAA are primarily nonspecific, and most patients remain undiagnosed, even those with large PAA, due to its silent course; however, clinical manifestations occur unless when there are complications such as bronchial or tracheal compression (leading to cough and dyspnea), dissection, or rupture (leading to hemoptysis). PAH is observed in 66% of patients with PAA. PA dissections are usually associated with PAH; 80% of dissections occur in the main pulmonary trunk. Although there is no clear guideline for the best treatment of PAA, surgery is indicated in patients with a pulmonary trunk aneurysm >5.5 cm. It has been observed that patients in the PAH group associated with congenital heart disease tend to develop PAA more commonly. Those with PAH associated with connective tissue disease have a smaller diameter of PA dilation. This report presents a comprehensive review of PAA, discussing critical aspects of the clinical and imaging diagnosis, hemodynamics, and treatment. A comprehensive updated literature review is included; we believe this article will interest cardiopulmonologists.

Pulmonary hypertension is a hemodynamic state defined by a mean pulmonary arterial pressure >20 mmHg and a pulmonary vascular resistance ≥3 WU, subdivided into 5 groups. Chronic Thromboembolic Pulmonary Hypertension (CTEPH) corresponds to group 4. The antiphospholipid syndrome is one of the most associated thrombophilia, with a prevalence of CTEPH of 2%-50%. A case-control study was conducted where data from the Right Cardiac Catheterization Registry of the PH Clinic were collected, with a diagnosis of CTEPH in patients aged 18-60 years and any sex. Antiphospholipid Syndrome (APLS) patients were separated from those with only CTEPH. It was developed in a statistical analysis based on frequencies, means, and standard deviation. The variables were evaluated using the Kolmogorov-Smirnov, Student's T, Mann-Whitney U, and Chi-Square tests with a 95% confidence interval. A total of 12 patients with APLS diagnosis and 30 without it were identified. The comparison between both groups shows that the patients with APLS were younger (38 ± 14.35 vs 51.63 ± 15.02 years, P 0.010) and had a significant association with autoimmune diseases (25% vs 0%, P 0.003). The patients diagnosed with APLS were primarily men (7 vs 5), and no statistically significant difference was found between laboratory and hemodynamic parameters. Patients diagnosed with CTEPH and APLS are mainly male, younger mean age, and have a greater significant association with autoimmune diseases than patients with CTEPH.

Pulmonary embolism (PE) worldwide is an underdiagnosed disease; at the moment, there are no statistical data to make inferences regarding the thrombotic problem in Mexico. Although, in general, small emboli (subsegmental) are well tolerated in the pulmonary circulation, difficulties frequently occur for medium to large emboli that occlude more than 30% of the pulmonary circulation. In the United States, it is estimated that up to 100,000 PE-related deaths occur each year. A PE code consists of activating a group of specialists in PE for the consensual making of therapeutic decisions; it is beneficial for the clinical evolution of these patients and reduces their mortality; a PE response team (PERT) codes in reference hospitals to manage this disease. This report presents an updated summary of the PERT status globally and in Mexico, the explanation of why a PE code is necessary, and the effects of PERT teams in the detection (chronic thromboembolic pulmonary hypertension, chronic thromboembolic disease, and venous thromboembolism); therapeutic procedures (catheter-directed thrombolysis, systemic thrombolysis or surgical thrombectomy); selection of patients from low to high risk of PE; and future directions for PERT teams.

The classic definition of pulmonary arterial hypertension (PAH) is a mean pulmonary artery pressure (mPAP) of 20 mmHg. The gold standard for assessing pulmonary hemodynamics is right heart catheterization (RHC), which is necessary to confirm the diagnosis of PH. In some instances, RHC evaluates the degree of hemodynamic dysfunction and performs vasoreactivity tests. Measurement of the hepatic venous pressure gradient remains the gold standard diagnostic for identifying portal hypertension. This review aims to describe the procedure of RHC and the hemodynamic measurement in patients with PAH and Portopulmonary hypertension (PoPH). The RHC remains the gold standard for diagnosing PAH and PoPH.

Pulmonary hypertension (PH) is a hemodynamic condition with different etiological groups but common pathophysiology. Gender differences have been studied in group 1 of the PH classification, the pulmonary arterial hypertension (PAH) group. PAH has an etiopathogenic basis in sex hormones and directly affects the pulmonary vasculature and the heart. Gender differences are observed before and after the age of 45 when women lose the cardioprotective effect of estrogen. A retrospective cohort study in adult patients ≤45 years and >45 years. We compared hemodynamic, echocardiographic, and imaging variables that demonstrated gender differences in adult patients with PAH below and above 45 years. Gender differences in adults ≤45 years were significant for the pronounced pulmonic component of the second heart sound (P2) and the right atrium pressure, on the other hand, more significant sex differences were observed in patients over 45 years of age including the pronounced pulmonic component of P2 (greater in women), the brain natriuretic peptide had a higher median in men, the same happened in the echocardiographic data referring to the area of the right atrium and tricuspid annular plane systolic excursion, abnormal values predominate in men. Although PAH has greater incidence and prevalence in women, the lesions corresponding to cardiac remodeling that subsequently led to right ventricular failure are more remarkable in men, raising their mortality. These findings help recognize its clinical usefulness and propose new research studies aimed at mortality and new pharmacological therapies that might unveil the pathophysiological mechanisms to treat PAH.
