It is with profound interest that we read the manuscript by Karahan et al. titled “Evaluation of Frontal QRS-T Angle in Patients with Coronary Artery Ectasia” published in the recent volume of International Journal of Cardiovascular Sciences . Coronary artery ectasia (CAE), a condition marked by focal enlargement of coronary arteries, has long intrigued researchers and clinicians due to its enigmatic nature. Beyond its silence existence, CAE hides a spectrum of clinical ranges, from chest pain with coexisting coronary artery […]

Heart failure (HF) is a significant and growing public health problem. Recent projections have shown that the prevalence of HF in the United States will increase by 46% between 2012 and 2030. This is driven by an increase in the life expectancy of the population combined with a reduction in mortality from the disease resulting from advances in therapies in recent years. Of all the classifications of HF, the most used one is based on left ventricular ejection fraction (LVEF), […]

Snakes, scorpions, spiders, wasps, and fish have evolved independent venom systems with complex mixtures in their chemical arsenals. Envenomation after a snakebite is a neglected public health issue responsible for substantial illness and death in impoverished populations living in rural and tropical Africa, Asia, Oceania, and Latin America. Considering the elevated number of accidents and high morbidity and mortality rates associated with snakebite envenoming, the World Health Organization has reclassified this disease as a category A neglected disease. In Latin […]

Latin America (LA) is characterized by enormous cultural diversity due to its multiplicity of languages (Spanish, Portuguese, French, English, Dutch, and countless indigenous languages), ethnicities (white, black, indigenous), beliefs, climates, religions, and customs. This variability is observed between countries and within each country in the region, making them unique, even though they share a geographic area and numerous historical facts. There is evidence that the epidemiological and nutritional transition has been more heterogeneous in LA than in other areas of […]

Since the declaration of the coronavirus disease 2019 (COVID-19) pandemic in March 2020, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, much has been learned about the epidemiology, pathophysiology, clinical characteristics, and predictors of poor prognosis. Furthermore, cardiovascular implications have emerged as significant contributors to morbi-mortality. In this sense, the recently published work of Galindes-Casanova et al. reinforces existing evidence on acute COVID-19 infection, cardiac complications, and electrocardiogram (ECG) manifestations. By the end of 2023, COVID-19 had […]

In recent decades, significant advances have been made in the early detection and treatment of different types of cancer, which have led to a significant worldwide increase in the number of survivors of this group of diseases, with estimates that two-thirds of all survivors would be 65 years old or older in 2020. There are currently more than 32 million cancer survivors worldwide and this number is expected to continue growing, due to efficient screening for the disease and increased […]

Congenital cardiovascular malformations (CCVMs) are structural abnormalities of the heart or blood vessels present during fetal life and at birth. From 2010 to 2017, the incidence of CCVMs was estimated at 9.4 cases per 1,000 live births in countries in Southeast Asia and the Northern Hemisphere. During the same period, rates in Brazil ranged from 9.7 (in the northern region) to 62.8 (in the southeastern region) per 1,000 live births, and similar values have been reported by the Global Burden […]
