The Simultaneous Occurrence of Acute ST-Elevation Myocardial Infarction, Acute Ischemic Stroke, and Pulmonary Embolism.

Acute ST-elevation myocardial infarction (STEMI), acute ischemic stroke (AIS), and acute pulmonary embolism (PE) are life-threatening conditions, each posing a high risk of morbidity and mortality. When all three of these acute conditions occur simultaneously, the overall prognosis for the patient becomes considerably worse. We report a case of a 70-year-old woman who presented to the emergency department (ED) with a triad of acute STEMI, AIS, and PE as a consequence of atherosclerotic heart disease, atrial fibrillation, and a prolonged transatlantic flight. The diagnoses were promptly confirmed through emergent coronary and cerebral angiography, along with a computerized tomography pulmonary angiogram (CTPA). The patient underwent a combination of medical therapy and endovascular thrombectomy. However, she later developed a subarachnoid hemorrhage and eventually progressed to brain death.

Brain Abscess Caused by Nocardia farcinica in a Young Immunocompetent Patient.

Cerebral nocardiosis is a rare opportunistic infectious disease that occurs mainly in immunocompromised hosts; however, immunocompetent patients may be affected too. It often results in the formation of intraparenchymal brain abscess, which represents only 2% of all cerebral abscesses. The overall mortality rate exceeds 20% in immunocompetent patients and 55% in immunocompromised patients. Bacteriological diagnosis is often confirmed only after the surgical excision of the abscess. Thus, the initiation of effective therapy is frequently delayed. Our goal is to highlight a diagnostic approach to cerebral nocardiosis in an immunocompetent patient with the purpose of accelerating the initiation of the appropriate therapy. We report a rare case of brain abscess caused by Nocardia farcinica in a 39-year-old male, a resident of New York City, USA, with a past medical history of intravenous (IV) drug use, who was admitted for altered mental status. The patient was cachectic and ill-appearing. Initial laboratory tests showed neutrophilic leukocytosis. Computed tomography (CT) of the head revealed a large ill-defined multilobulated mass of size 6 × 5 × 4.5 cm in the right cerebral hemisphere, which was confirmed with magnetic resonance imaging (MRI). The hospital course was complicated by the deterioration of mental status requiring endotracheal intubation. The patient underwent a right-sided hemicraniectomy; a wound culture identified Nocardia farcinica. The patient was started on intravenous (IV) Bactrim, which caused an allergic reaction. Thus, he was switched to IV imipenem-cilastatin. After E-test was performed, the patient was switched to oral linezolid. The initiation of targeted antibiotic therapy was crucial for the management of this patient and resulted in a good clinical outcome. In conclusion, cerebral nocardiosis, being an unusual and a potentially fatal infection, should be considered in the differential diagnosis of brain abscess even in immunocompetent hosts. Prompt bacteriological diagnosis helps to initiate a specific antimicrobial therapy. Long-term antimicrobial therapy and long-term follow-up are necessary to prevent relapse.

Left Ventricular Noncompaction Cardiomyopathy in an Elderly Patient: A Case Report and Literature Review.

Isolated left ventricular noncompaction cardiomyopathy (LVNC), also known as spongy myocardium, is an extremely rare congenital disorder belonging to unclassified cardiomyopathies by the World Health Organization and classified as a genetic cardiomyopathy by the American Heart Association. Adult prevalence is 0.017-0.26% in observational echocardiographic studies. The disease occurs due to the intrauterine arrest of normal myocardial compaction, leading to left ventricular dysfunction. Reported mortality is high, ranging from 35 to 47% over a 42- to 72-month follow-up period. Knowledge regarding proper diagnosis, morbidity, and prognosis is limited; thus, this disease is subdiagnosed. Our aim is to highlight a diagnostic approach to LVNC in an elderly patient and to stress specific diagnostic signs that make the disease more recognizable. We are reporting a case of noncompaction cardiomyopathy in a 62-year-old male without any significant past medical history who was referred to our clinic for arrhythmia evaluation. The patient had several brief episodes of palpitations over the past two months. On physical examination, he presented a blowing systolic murmur at the apex and an irregularly irregular rhythm. The 12-lead electrocardiogram (ECG) demonstrated atrial fibrillation and ST-T segment depression in the V4-V6 leads. A transthoracic echocardiogram (TTE) showed signs of dilated cardiomyopathy, severe eccentric left ventricular hypertrophy, decreased contractility with an ejection fraction (EF) <30%, moderate mitral and tricuspid regurgitations, and moderate pulmonary hypertension. Multiple prominent trabeculations were noticed in the middle and apical segments of the left ventricle. The noncompacted to compacted myocardium ratio was >2.5:1. Cardiac catheterization excluded ischemic heart disease. Cardiac magnetic resonance (CMR) imaging confirmed the diagnosis of LVNC. The patient started treatment with carvedilol, ramipril, verospiron, torasemide, and rivaroxaban. An implantable cardioverter-defibrillator (ICD) was recommended. In conclusion, the diagnosis of LVNC in the adult population is often delayed because of similarities with more frequently diagnosed diseases. TTE is the initial diagnostic test of choice. Additional imaging modalities (contrast echocardiography, CMR) can help confirm the diagnosis. Early diagnosis is crucial because of the high incidence of life-threatening complications related to heart failure, thromboembolic events, and ventricular arrhythmias. Additional prospective studies are needed to improve the management and outcomes of this rare cardiomyopathy.
