Background: Electrocardiographic (ECG) abnormalities are prevalent in subjects with human immunodeficiency virus (HIV) infection. In this study, three groups of subjects were investigated and the prevalence of ECG abnormalities was analysed.
Methods: A cross-sectional study was carried out on adults between November 2010 and November 2011 at the University of Nigeria Teaching Hospital, Enugu, Nigeria. One hundred HIV-infected patients on highly active anti-retroviral therapy (HAART), 100 HIV-infected HAART-naïve patients and 100 HIV-negative controls were recruited. Twelve-lead electrocardiograms were done on all subjects. Data were analysed using the chi-squared, Student's t-, one-way ANOVA and Duncan post hoc tests.
Results: Left-axis deviation was seen in 15 (16%) of the HIV-positive subjects on HAART, 10 (13.7%) of the HAART-naïve subjects and eight (21%) of the controls (p = 0.265). Eight (11%) subjects with left ventricular hypertrophy (p < 0.001) and two (2.7%) with ST-segment elevation were found among the HIV-positive HAART-naïve subjects (p = 0.134). Prolonged QTc interval was seen in 17 (18.2%) of the HIV-positive patients on HAART, 12 (16.4%) of the HIV-positive HAART-naïve patients and four (10.5%) of the controls (p = 0.012).
Conclusion: The prevalence of ECG abnormalities was higher in the HIV-positive patients on HAART (93%) and the HIV-positive HAART-naïve patients (73%) compared to the controls.

A dynamic variant of Takotsubo cardiomyopathy mimicking apical hypertrophic cardiomyopathy: a case report.
Eur Heart J Case Rep

Cardiovascular and Thoracic Division, Cardiology Department, University Hospital Southampton, Tremona Road, Southampton SO16 6YD, UK.
Background: Takotsubo cardiomyopathy usually presents with acute reversible left ventricular apical hypokinesia and apical ballooning with basal hyperdynamic function. We describe an underreported case of Takotsubo cardiomyopathy (TCM), misinterpreted as apical hypertrophic cardiomyopathy (HCM) due to transient apical oedema in the recovery phase of the condition.
Case Summary: A 74-year-old Caucasian woman, presented to the emergency department complaining of retrosternal chest pain following, emotional stress.

Background: Immune checkpoint inhibitors (ICIs) are effective antineoplastic agents but can cause adverse effects in many organ systems. Cardiovascular toxicities include arrhythmias, myocarditis, heart failure, takotsubo syndrome, pericarditis, coronary artery disease, and vasculitis.

Purpose Of Review: This paper reviewed the current literature on incidence, clinical manifestations, and risk factors of Chimeric Antigen Receptor T-cell (CAR-T) cardiotoxicity.
Recent Findings: CAR-T therapy has emerged as a groundbreaking treatment for hematological malignancies since FDA approval in 2017. CAR-T therapy is however associated with a few side effects, among which cardiotoxicity is of significant concern.

Unlabelled: A 93-year-old man was admitted to our hospital with complaints of pain and coldness in both lower legs. He was diagnosed with arterial occlusive disease of the lower extremities. There were no obvious stenosis or occlusion of lower extremity arteries, which would be indications for surgery, and drug therapy was started.

Background: Long-term exercise training induces various morphological adaptations in the heart. Although concentric left ventricular (LV) geometry is occasionally observed in young athletes, its clinical significance is unclear. This study aimed to investigate the characteristics of young rugby athletes with concentric LV geometry and considered its clinical implications.
