RESUMO
Thyrotoxic periodic paralysis (TPP) and thyrotoxic cardiomyopathy (TCMP) are potentially lethal complications of thyrotoxicosis that require emergent recognition and management to attenuate significant morbidity and mortality. We present the case of a 23-year-old Asian male with no prior medical history who developed TPP with coincident TCMP, which was successfully managed with antithyroid and heart failure therapies. The clinician should be aware of the diagnosis and treatment of these 2 life-threatening conditions in a hyperthyroid state.

Recent studies suggest a potential association between myocardial bridging (MB) and accelerated atherosclerotic plaque formation. We describe the case report of a 37-year-old South Asian male with no established risk factors for coronary artery disease (CAD) who presented with a non-ST-segment-elevation acute coronary syndrome (NSTE-ACS) with a coincident widowmaker lesion and severe MB. He was successfully managed with comprehensive guideline-directed medical therapy (GDMT) and urgent percutaneous coronary intervention (PCI) of the culprit lesion, sparing the MB segment. The clinician should be cognizant of MB implicating ACS as a major adverse cardiovascular event (MACE) and its key management strategies.
RESUMO
We present a case of a 15-year-old South Asian male who developed suspected postural orthostatic tachycardia syndrome (POTS) two weeks after receiving the Pfizer-BioNTech coronavirus disease 2019 (COVID-19) vaccine booster, which was successfully managed with low-dose fludrocortisone and ivabradine. Clinicians should be aware of the Pfizer-BioNTech COVID-19 vaccine being implicated with the onset of POTS.
RESUMO
The South African flag sign (SAFS) is an acute, dynamic electrocardiographic (ECG) finding typically associated with first diagonal (D1) artery occlusion. We report the case of a 47-year-old woman who exhibited this pattern but subsequently revealed the dreaded "widow-maker" lesion (100% occluded proximal left anterior descending [LAD] artery) and severe multivessel disease (90% stenosis of the posterior left ventricular [PLV] artery and 80% stenosis of the left circumflex artery [LCx]).

We present the case of a 23-year-old man with a previous deceased-donor renal transplant maintained on tacrolimus and prednisone who developed culture-negative endocarditis (CNE) of the mitral and aortic valves. He was suspected of being co-infected with Bartonella henselae and Coxiella burnetii, confirmed with serology testing. He was successfully managed with appropriate antibiotics and dual valve replacement.

Cardiac manifestations in leptospirosis usually involve atrial arrhythmias, conduction abnormalities, and nonspecific ST-T changes, while left ventricular dysfunction is rare. We present the case of a 45-year-old male without a pre-existing cardiovascular history who developed atrial fibrillation and atrial and ventricular tachycardia, in addition to new-onset cardiomyopathy in the setting of fulminant leptospirosis infection.

INTRODUCTION: This study aimed to determine whether there was any correlation between coronary artery disease (CAD) and retinal artery diameter at an academic tertiary medical center in Trinidad and Tobago. METHODS: This prospective study evaluated patients (n = 77) with recent invasive coronary angiography (CAG) and the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score who subsequently underwent optical coherence tomography-angiography (OCT-A) at the Eric Williams Medical Sciences Complex (EWMSC) from January 2021 to March 2021. Routine medical history and cardiovascular medications were also recorded. Spearman's rank correlation coefficient and Mann-Whitney U-tests were used to compare correlations and medians between groups. RESULTS: The average patient age was 57.8 years old, with the majority being male [n = 55 (71.4%)] and of South Asian ethnicity [n = 53 (68.8%)]. Retinal artery diameter was negatively correlated with the SYNTAX score (-0.332 for the right eye, p = 0.003 and -0.237 for the left eye, p = 0.038). A statistically significant relationship was also demonstrated in females and diabetic patients. There were no serious adverse events (SAEs). CONCLUSION: A significantly negative correlation was observed between retinal artery diameter and SYNTAX score. This study alludes to the practical use of optical coherence tomography-angiography (OCT-A) as a noninvasive diagnostic modality for patients with cardiovascular disease (CVD). Further large-scale, multicentric studies are required to confirm these exploratory findings. TRIAL REGISTRATION NUMBER: NCT04233619.
RESUMO
Pericardial effusions refer to an excess accumulation of fluid within the pericardial cavity. The etiology is diverse, with most cases being idiopathic in nature. We report a case of suspected cannabis vaping-induced pericardial effusion in a 31-year-old South Asian patient, which was successfully managed with high-dose aspirin, colchicine therapy, and cannabis vaping cessation.Key Clinical Message: Clinicians should be aware of the possible cardiovascular complications of cannabis vaping.

We present the case of a 26-year-old man, without any apparent cardiovascular risk factors, who experienced an ST-segment-elevation acute coronary syndrome after binge drinking high-proof alcohol, which was successfully managed with primary percutaneous coronary intervention and comprehensive, guideline-directed medical therapy.

Several psychiatric disorders, including juvenile Attention Deficit/Hyperactivity Disorder (ADHD), have been associated with abnormalities of certain long-chain PUFA (LCPUFA). Despite this reported association, the FA levels of patients with the adult form of ADHD have not previously been evaluated. In this study we measured the total blood phospholipid FA concentrations in 35 control subjects and 37 adults with ADHD symptoms to determine whether adults with ADHD symptoms would show abnormalities of FA relative to control subjects. In the serum phospholipids, adults with ADHD symptoms had significantly lower levels of total saturated, total polyunsaturated, and total omega-6 (n-6) FA, as well as the omega-3 (n-3) LCPUFA DHA (22:6n-3), and significantly higher levels of total monounsaturated FA and the n-3 LCPUFA docosapentaenoic acid (22:5n-3). In the erythrocyte membrane phospholipids, adults with ADHD symptoms had significantly lower levels of total PUFA, total n-3 FA, and DHA, and significantly higher levels of total saturated FA. Neither serum nor erythrocyte membrane phospholipid DHA was related to ADHD symptom severity (as assessed by the Amen questionnaire) in ADHD subjects. Although the exact cause of these variations is unknown, both environmental and genetic factors may be involved.
