Role of Vitamins in Cardiovascular Health: Know Your Facts - Part 1
Curr Vasc Pharmacol. 2023 Sep 12. doi: 10.2174/1570161121666230912155548. Online ahead of print.ABSTRACTCardiovascular (CV) disease (CVD) is a major cause of morbidity and mortality world-wide, thus it is important to adopt preventive interventions. Observational data demonstrating CV benefits of vitamin supplements, advanced by self-proclaimed experts have resulted in ~50% of Americans reporting the use of multivitamins for health promotion; this practice has led to a multi-billion-dollar business of the multivitamin-industry. However, the data on the extensive use of multivitamins show no consistent benefit for CVD preve...

Role of Vitamins in Cardiovascular Health: Know Your Facts-Part 2
Curr Vasc Pharmacol. 2023 Sep 11. doi: 10.2174/1570161121666230911115725. Online ahead of print.ABSTRACTCardiovascular disease (CVD) is a major cause of morbidity/mortality world-wide, hence preventive interventions are crucial. Observational data showing beneficial CV-effects of vitamin supplements, promoted by self-proclaimed experts, have led to ~50% of Americans using multivitamins; this practice has culminated into a multi-billion-dollar business. However, robust evidence is lacking, and certain vitamins might incur harm. This two-part review focuses on the attributes or concerns about specific vitamin consumption on ...

Rational clinical approach to transient ischaemic attack, stroke and associated mimics: A retrospective cohort study
CONCLUSIONS: The present study demonstrated that specific clinical features and risk factors were associated with the final diagnosis at TIA clinic. These clinical features may assist with diagnosis of TIA in centres without access to a vascular neurologist.PMID:37190670 | DOI:10.1111/1742-6723.14238

Po-02-140 central retinal artery occlusion: a systematic review and meta-analysis for the risk of new-onset atrial fibrillation and stroke
Central retinal artery occlusion (CRAO) is a devastating event and atrial fibrillation (AF) is a recognized cause that may not be present at the time of the event.

Mitral Valve Blood Cyst and Multi-Territory Ischaemic Stroke
A 78-year-old male with a history of hypertension and hypercholesterolaemia was admitted to hospital with acute left eye visual loss and diagnosed with retinal artery occlusion. Magnetic resonance imaging (MRI) revealed multiple, bilateral cerebral infarcts involving supra- and infra-tentorial brain consistent with acute ischaemic stroke from a central embolic source. Extended ambulatory electrocardiographic monitoring displayed sinus rhythm with no evidence of atrial flutter or fibrillation. Transthoracic echocardiography (TTE) revealed a cystic structure associated with the mitral valve, with no restriction or regurgitation.

Differences in retinal microvasculature between large artery atherosclerosis and small artery disease: an optical coherence tomography angiography study
Conclusions: We found LAA patients had significantly reduced DVC density compared with SAD; we also showed anterior LAA patients had significantly reduced SVC density compared with posterior LAA. These findings suggest retinal imaging has the potential to be used to detect microvasculature changes in subtypes of ischemic stroke.PMID:36620764 | PMC:PMC9816383 | DOI:10.3389/fnagi.2022.1053638

Risk factors for ischemic cerebral stroke in patient with acute amaurosis fugax
CONCLUSION: Ischemic stroke and myocardial infarction were diagnosed in 0.3%-0.9% of hospitalized acute AF cases. Presence of hypercoagulable state, systemic vasculitis, CAD, and atherosclerosis each individually increased the risk of ischemic stroke by more than 3-fold; patients with these risk factors and acute AF should be closely monitored for developing acute systemic thrombotic events.PMID:36368408 | DOI:10.1016/j.jcjo.2022.10.010

Outcomes and Readmission in Patients With Retinal Artery Occlusion (from the Nationwide Readmission Database)
Retinal artery occlusion (RAO) is an ophthalmologic emergency, leading to sudden vision loss. Understanding its risk factors and garnering information on the incidence of adverse events can provide helpful information on the cost-effective evaluation of patients and secondary prevention. In this retrospective cohort study, we used the Nationwide Readmission Database from 2016 to 2018 and queried the database to identify patients with RAO. The clinical outcomes were cumulative incidence of myocardial infarction (MI), stroke, death (in-hospital and 6 months after discharge), resource utilization, all-cause readmission at 6 m...

Similarities and differences in systemic risk factors for retinal artery occlusion and retinal vein occlusion: A nationwide case-control study
CONCLUSION: Differences in the level of associations with the included risk factors suggests differences in the pathophysiologies of the two diseases. The main pathophysiology associated with RAO was atherosclerosis, whereas the main pathophysiology associated with RVO was changes in the pressure gradients of the eyes.PMID:36056288 | DOI:10.1007/s10792-022-02483-3
