Acute Thrombotic Occlusion of proximal Left Anterior Descending Artery without ST-elevation (de Winter sign) in Electrocardiogram: A Case Report

Introduction: ST-elevation in precordial leads is diagnostic for acute transmural myocardial infarction (MI) related to acute occlusion of left anterior descending artery (LAD). Case presentation: In this case report, a 54-year-old man was admitted to the emergency department (ED) due to chest pain. ST-depression with tall T waves in precordial leads was detected in surface electrocardiogram (ECG). Angiography showed acute total occlusion of proximal LAD and ad hoc percutaneous coronary intervention (PCI) was performed successfully. Conclusion: This case highlights that total occlusion of LAD may present without typical ST-elevation pattern in ECG

Acute Gastric Dilation Following Trauma: A Case Report

Introduction: Acute gastric dilation following trauma is an unusual event that can occur in different settings, and can cause gastric necrosis as a rare though fatal condition. The present report involves a case of acute gastric dilation following multiple traumas, which caused gastric necrosis and total gastrectomy. Case presentation: A 19-year-old morbid obese male presented to the emergency department (ED) following a motor vehicle accident. He had a left lower extremity crash injury. In his serial examinations, he was complaining of upper abdominal pain with epigastric tenderness. After nasogastric tube (NGT) reinsertion, due to detecting coffee ground secretions in the drained fluid, the patient was transferred to the operating room. A midline laparotomy was performed that revealed dilation and discoloration of the stomach. Gastric decompression was performed. All the discoloration then disappeared except for that of certain suspicious areas, which necessitated evaluations. On the following day, given the lack of improvement in the patient`s condition, he was transferred to the operating room for a second laparotomy. Conclusion: The present report emphasized on the importance of NGT insertion in multiple-trauma patients, which is, however, neglected in many cases. Moreover, acute gastric dilation is recommended to be considered in the differential diagnosis of patients with multiple or abdominal trauma and complaints of vomiting or abdominal pains

Familial Hypercholesterolemia in the Electronic Medical Records and Genomics Network: Prevalence, Penetrance, Cardiovascular Risk, and Outcomes After Return of Results

BACKGROUND: The implications of secondary findings detected in large-scale sequencing projects remain uncertain. We assessed prevalence and penetrance of pathogenic familial hypercholesterolemia (FH) variants, their association with coronary heart disease (CHD), and 1-year outcomes following return of results in phase III of the electronic medical records and genomics network. METHODS: Adult participants (n=18 544) at 7 sites were enrolled in a prospective cohort study to assess the clinical impact of returning results from targeted sequencing of 68 actionable genes, including RESULTS: The prevalence of FH-associated pathogenic variants was 1 in 188 (69 of 13,019 unselected participants). Penetrance was 87.5%. The presence of an FH variant was associated with CHD (odds ratio, 3.02 [2.00-4.53]) and premature CHD (odds ratio, 3.68 [2.34-5.78]). At least 1 outcome occurred in 92% of participants; 44% received a new diagnosis of FH and 26% had treatment modified following return of results. CONCLUSIONS: In a multisite cohort of electronic health record-linked biobanks, monogenic FH was prevalent, penetrant, and associated with presence of CHD. Nearly half of participants with an FH-associated variant received a new diagnosis of FH and a quarter had treatment modified after return of results. These results highlight the potential utility of sequencing electronic health record-linked biobanks to detect FH

Management of Pulmonary Embolism and Pericardial Effusion

Pulmonary embolism is a serious complication occurring in different cancers. Patients who have cancer may have complications like brain metastasis or pericardial effusion, which may change the therapeutic management of pulmonary embolism. In this article, a patient is presented with lung adenocarcinoma resulting in pericardial effusion. He was admitted with pulmonary embolism and atrial flutter, which made his management difficult.</jats:p

Portal Vein Thrombosis and Budd-Chiari Syndrome as the Initial Symptom of Polycythemia Vera and Hyperhomocysteinemia

Portal Vein Thrombosis (PVT), commonly associated with cirrhosis of liver and thrombophilia, is one of the causes of severe abdominal pain. In the absence of non-cirrhotic non-malignant extrahepatic portal vein thrombosis, Myeloproliferative Disease (MPD) and an underlying thrombotic disorder should always be suspected and investigated. Hyperhomocysteinemia has been well-documented to increase the risk of arterial thrombotic events, peripheral arterial disease, and stroke. It is also a risk factor for deep-vein thrombosis. In the general population, association with portal vein thrombosis is very unusual, and only a few cases have been reported. We describe a case of Polycythemia Vera (PV) and hyperhomocysteinemia presenting with severe abdominal pain due to portal vein thrombosis. The patient underwent phlebotomy and was prescribed life-long anticoagulant, aspirin, vitamin B6, vitamin B12, and folic acid, then referred to a hematologist.</jats:p

Usefulness of Biomarkers for Predicting Response to Cardiac Resynchronization Therapy

: Cardiac Resynchronization Therapy (CRT) is an effective treatment strategy for heart failure. It significantly improves clinical symptoms and decreases mortality and long-term morbidity. However, some patients do not respond properly to this treatment. In this review, the role of different biomarkers in predicting response to CRT is discussed. Some biomarkers, including natriuretic peptides and inflammatory markers have promising results but further trials are needed for more evaluation. Methods: All the studies reporting the extent of biomarkers for predicting the response to cardiac resynchronization therapy were included in this study. For studies using the same database, the ones with a higher number of cases and more complete data were included. Conclusions were drawn from relevant randomized controlled clinical trials and meta-analyses about CRT implantation and its associated alterations in biomarker levels. Cardiac Resynchronization in Heart Failure (CARE-HF) study was the first and the largest study on patients with CRT with the longest followup, which showed a significant correlation between BNP levels and long-term CRT outcome. CRP has been demonstrated to be a mediator of inflammation and a marker indicating the presence of an inflammatory process. Conclusion: Natriuretic peptides, including BNP, markers of collagen synthesis like PINP, inflammatory markers, especially CRP, gal-3, and CT-apelin yield promising results in left ventricular remodeling and their relationship with response to CRT implantation is seen. Although more research is needed in this area as little information is available for baseline and preprocedural measurements, so that it would be easy to choose appropriate candidates for CRT implantation. </jats:sec

Additive value of positron emission tomography/computed tomography scan for detection of aortic tube graft infection: a case report

AbstractBackgroundDiagnosis of aortic graft infection is challenging, and delayed diagnosis is associated with poor prognosis. Positron emission tomography/computed tomography (PET/CT) has improved diagnostic accuracy.Case summaryA patient with a history of congenital heart disease was admitted due to fever. He had a history of four cardiac surgeries, including the Bentall procedure for endocarditis. Blood cultures were negative. A semi-mobile mass was detected in the distal portion of the aortic tube graft in echocardiography. PET/CT scan was used to confirm tube graft infection and to support proceeding to cardiac surgery.DiscussionUsing multimodality imaging, including PET/CT scan in combination with echocardiography, can improve diagnostic accuracy for the detection of aortic tube graft infection, infection of prosthetic valves, or intra-cardiac devices, especially in high-risk surgical cases.</jats:sec
