Exploring the Heart Failure Connection in Long COVID Patients: A Narrative Review.

In this narrative review, we explore the relationship between long COVID patients and their risk of developing heart failure (HF). Patients with long COVID face a heightened risk of HF, a critical cardiovascular complication linked to the prolonged effects of COVID-19. Clinical manifestations of long COVID-associated HF present diagnostic challenges, complicating patient management. Multidisciplinary care is essential to address these complexities effectively. We found that long COVID can result in various cardiovascular issues including HF. The current view is long COVID leads to HF by activating systemic inflammation by causing endothelial dysfunction, which leads to activation of the complement pathways, tissue factor pathways, and Von Willebrand factor; activation of all these factors leads to venous and arterial thrombosis, which could lead to clogging of blood vessel of the heart leading to cardiovascular complications. The association between long COVID and HF can be challenging despite being recognized as comorbidity because biomarkers are not dependable in determining whether a patient had HF before or after contracting COVID-19. Emerging therapeutic modalities offer hope for improving outcomes, but further research is needed to refine management strategies and mitigate long-term cardiovascular consequences of COVID-19.

A Rare Case of Congenital Left Ventricular Diverticulum With Apical Thrombus: Diagnostic Challenges and Management Insights.

A myocardial diverticulum is a rare congenital anomaly characterized by pouch-like protrusions within the myocardial wall, which can potentially lead to various cardiac complications. This case report describes a unique presentation of a left ventricular diverticulum (LVD) with an associated apical thrombus, highlighting the diagnostic and management challenges posed by this condition. A 58-year-old man presented to the emergency department with left arm weakness, wrist drop, and chest pain, initially raising concerns for a stroke. Diagnostic evaluations, including echocardiography and magnetic resonance imaging (MRI), revealed a small focal outpouching at the left ventricular apex, consistent with a congenital LVD containing a thrombus. This diagnosis was supported by the patient's historical imaging dating back to 2007, which had similarly identified this outpouching. The patient was managed with anticoagulation therapy, transitioning from heparin to warfarin, alongside standard cardiac care. This case underscores the importance of considering myocardial diverticulum in the differential diagnosis of patients presenting with cardiac symptoms that might initially suggest more common conditions, such as stroke. It also highlights the essential role of echocardiography and MRI in diagnosing and managing myocardial diverticula.

Spontaneous Coronary Artery Dissection: An Updated Comprehensive Review.

Spontaneous coronary artery dissection (SCAD) is defined as a non-iatrogenic, non-traumatic separation of the coronary artery wall, which has gained considerable recognition as an important cause of acute coronary syndrome. Despite the emerging evidence, it is still frequently missed and requires a high index of suspicion, as failure to accurately identify SCAD promptly could prove fatal. SCAD is most prevalent among middle-aged women, although it can also be found in men and postmenopausal women. Risk factors of SCAD include exogenous hormone use, physical and emotional stressors, pregnancy, and several inflammatory and connective tissue disorders. COVID-19 also contributes to the prevalence of SCAD. SCAD is classified into four main types based on the angiographic findings - type 1, type 2, type 3, and type 4. The gold standard for diagnosis is coronary angiography; however, intracardiac imaging is useful if diagnostic doubts persist. Despite the increasing recognition of this disease, there is a paucity in the guidelines on the management of SCAD. Management may be conservative, medical, or interventional. Cardiac rehabilitation is also necessary in the management of patients with SCAD. In light of the gaps in evidence, the authors aim to provide a comprehensive review of the existing literature, outlining the pathophysiology, classification, and, most importantly, the evidence and pitfalls circulating diagnosis, acute, and long-term management of SCAD.

Unmasking the Silent Intruder: A Case of Spontaneous Coronary Artery Dissection.

Spontaneous coronary artery dissection continues to pose a diagnostic dilemma in the evaluation of patients with chest pain. Our case discusses its manifestation in a male patient who visited the emergency department complaining of recent-onset chest pain. Evaluation of his chest pain through coronary angiography revealed luminal radiolucency corresponding to type 1 spontaneous coronary artery dissection (SCAD). The patient was promptly managed using medical interventions until stability was achieved and referred to cardiac rehabilitation care with close follow-up. In our literary contribution, we present a fascinating diagnosis, potentially life-threatening, observed in an otherwise active and healthy male patient. Notably, this diagnosis is uncommon in the male population. Through this study, we aimed to shed light on understanding, awareness, and clinical recognition of SCAD, ultimately improving patient care and outcomes.

Wernicke's Encephalopathy: A Precipitation of Glycogen Storage Disease.

A 16-year-old Saudi female who is a known case of glycogen storage disease type 1A (GSD1A), presented to the emergency department at King Faisal Specialist Hospital, Riyadh, Saudi Arabia on 15th January 2021 due to a complaint of persistent vomiting. Two weeks after admission, she began developing double vision and progressive leg weakness with intact sensation. She received the primary management to maintain good hydration and was admitted to the ICU for further workup. Over her hospital course, multiple investigations were conducted, the most significant of which was the MRI after sudden ocular deterioration. The result depicted findings classic for Wernicke's encephalopathy (WE) on MRI. The patient was then started on Thiamine supplementation and MRI performed three weeks later showed significant interval improvement of the parenchymal signal abnormality with complete resolution features of Wernicke's encephalopathy. This complex case emphasizes the need for early recognition and immediate treatment with IV thiamine in such a potential condition that can lead to permanent neurological deficits that present in a non-typical fashion.
