Keeping prognostic assessment simple: The value of clinical features in normotensive cancer patients with pulmonary embolism.

Rev Port Cardiol (Engl Ed) 2019 Jun 12;38(6):407-415. Epub 2019 Jul 12.

Cardiology Department, Centro Hospitalar e Universitário de Coimbra, Pólo Hospitais da Universidade de Coimbra, Coimbra, Portugal.

Introduction: Although normotensive cancer patients with acute pulmonary embolism (PE) are a heterogeneous population, most validated clinical prognostic scores classify these patients as high-risk individuals, which limits their usefulness in this setting. In this study, we aimed to identify readily available clinical predictors of overall 30-day and one-year mortality in normotensive cancer patients with PE.

Methods And Results: We performed a retrospective single-center study that included all normotensive cancer patients with PE diagnosed by multidetector computed tomography (MDCT) during emergency department stay between January 2010 and December 2011. Read More

The dilemma of the "ischemic-looking" electrocardiogram: Pulmonary embolism or acute coronary syndrome?

Ann Card Anaesth 2019 Jan-Mar;22(1):89-91

Department of Radiology, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India.

Pulmonary embolism (PE) may be potentially fatal if not diagnosed and treated in time. Although specific electrocardiogram (ECG) findings often suggest the diagnosis of PE, occasionally, the ECG may mimic that of an acute coronary syndrome (ACS). We report an interesting case of a 45-year-old female presenting with sudden onset chest pain and shortness of breath with widespread ST depression in anterior precordial leads. Read More

Paradoxical brain embolism shadowing massive pulmonary embolism.

Am J Emerg Med 2018 08 20;36(8):1527.e1-1527.e2. Epub 2018 May 20.

AP-HP, CHU Henri Mondor, DHU A-TVB, Service de Réanimation Médicale, Créteil, F-94010, France; Université Paris Est Créteil, Faculté de Médecine, Groupe de recherche clinique CARMAS, Créteil, F-94010, France.

Patent foramen ovale is frequently observed in the general population. In case of massive pulmonary embolism, the sudden increase in the right heart cavity's pressure may cause a right-to-left shunting across this foramen, which could be associated with conflicting outcomes. Herein, we report a case of reversible cardiac arrest preceded by seizures, and followed by hemodynamic stability without any vasopressor. Read More

Niger J Clin Pract 2016 Nov-Dec;19(6):831-833

Department of Internal Medicine II, Clinic of Cardiology, Victor Babes University of Medicine and Pharmacy Timisoara, Timişoara, Romania.

In the last decades, an increased incidence of pulmonary embolism (PE) and acute dissection (AD) of aortic aneurysms has been registered mostly due to increased availability of advanced imaging techniques. They seldom occur concomitantly in the same patient. In this paper, we present the clinical challenges and controversies of diagnosis and therapy in a 70-year-old male patient with an atypical presentation of high-risk PE occurring concomitantly with a silent AD of a thoracic aortic aneurysm.

Normal ventricular diameter ratio on CT provides adequate assessment for critical right ventricular strain among patients with acute pulmonary embolism.

Int J Cardiovasc Imaging 2016 Jul 13;32(7):1153-61. Epub 2016 Apr 13.

Applied Imaging Science Laboratory, Department of Radiology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

There is variability in guideline recommendations for assessment of the right ventricle (RV) with imaging as prognostic information after acute pulmonary embolism (PE). The objective of this study is to identify a clinical scenario for which normal CT-derived right-to-left ventricular (RV/LV) ratio is sufficient to exclude RV strain or PE-related short-term death. This retrospective cohort study included 579 consecutive subjects (08/2003-03/2010) diagnosed with acute PE with normal CT-RV/LV ratio (<0. Read More

University of Ottawa, Ottawa hospital research institute, department of medicine, Ottawa, Canada; Université de Brest, department of internal medicine, EA 3878, CIC 1412, 29609 Brest, France.

Pulmonary embolism is the third cause of mortality by cardiovascular disease after coronary artery disease and stroke, and its incidence is around 1/1000 per year. During the last two decades, many different non-invasive diagnostic tests have been developed and validated. For hemodynamically stable outpatients, the diagnosis of acute pulmonary embolism mainly rests on the sequential use of clinical assessment, D-dimer measurement and multidetector CT. Read More
