Systemic arterial hypertension (SAH) is a chronic condition that is highly prevalent worldwide. It occurs without symptoms in most individuals and represents the main modifiable risk factor for cardiovascular disease. The adoption of behaviors that do not involve medication, such as changes in lifestyle and regular practice of physical exercise, along with strict adherence to prescribed medication, is a major challenge in the treatment of this disorder., The guidelines of the American Heart Association and the American College of Cardiology […]

Abstract Background: The 9p21 region is the most relevant locus associated with coronary heart disease in different populations. However, there are no studies that prove that this region is a risk factor in the Venezuelan population. Objectives: To analyze whether or not the 9p21 rs1333049 polymorphism is a risk factor for acute myocardial infarction (AMI) in Venezuelan patients, as well as to investigate its correlation with cardiovascular risk factors (CVRF), age of occurrence, type and severity of infarction, and the […]

Abstract Background The neuropeptide Y (NPY) is one of the most abundant neurotransmitters in the nervous system. NPY acts as a potent stimulator of angiogenesis, inflammation, and adipogenesis, through the NPY 2 receptor (NPY2R). Changes in the NPY signaling pathway have been linked to Acute Coronary Syndrome (ACS). Objectives The purpose of this study is to determine the association between variants in the NPY and NPY2R genes, as well as the severity of acute coronary syndrome (ACS). Methods Approximately 221 […]

Neuropeptide Y (NPY) is a very common neurotransmitter with 36 amino acids that acts as a stimulator of angiogenesis, inflammation and adipogenesis through the NPY2 receptor. The description of high plasma concentrations of NPY in acute coronary syndrome (ACS) and left ventricular dysfunction and its close relationship with the sympathetic nervous system reinforces the possibility of a new prognostic biomarker for risk stratification., In recent years, changes in the NPY signalling pathway have been related to ACS. For example, the […]

Abstract Background: Hyperthyroidism (Hy) is an endocrine disorder, in which the thyroid hormones markedly alter the cardiac function. Increased myocardial contractility and cardiac output, improvement in diastolic relaxation, changes in electrical activity, increments in ventricular mass, and arrhythmias have been reported. However, the influences of thyroid hormones upon molecular mechanisms of cardiac functions have not yet been fully understood. Objectives: To evaluate changes in cardiac contractile parameters and the Na+/Ca2+ exchanger (NCX) function in induced hyperthyroid rats. Methods: Hy was […]

Much information is lacking on hyperthyroidism and cardiac function, especially in isolated muscles. Certainly, the time the heart muscle is exposed to elevated thyroid hormones (TH) influences the magnitude of their effects. The primary changes seem to be related to increases in the heart mass/body mass ratio and in relaxation kinetics. These cardiac changes may also be related not only to the time of exposure to excess thyroid hormones, but to the level or intensity of hyperthyroidism, as well as […]

Abstract Background Infective endocarditis (IE) is a disease with high morbimortality and an increasing incidence. With improved diagnosis and treatment, a number of epidemiological changes have been reported over time. Objectives We sought to describe the epidemiological profile, mortality predictors, and analysis of a possible microbiological transition in patients admitted to three tertiary centers in Brazil. Methods In this cross-sectional retrospective study, data from 211 patients with definite or probable IE were analyzed according to the modified Duke criteria between […]

Abstract Background: Sarcopenia is a disease that involves skeletal muscle mass loss and is highly prevalent in the older adult population. Moreover, the incidence of sarcopenia is increased in patients with hypertension. Objectives: The study aimed to evaluate the association between the classes of the drugs used for arterial hypertension treatment and the presence or absence of sarcopenia. Methods: 129 older adults with hypertension were evaluated by the researchers who registered the participants medication for arterial hypertension treatment. Sarcopenia level […]

Hypertension is a chronic disease with high prevalence in Brazil and worldwide. It is estimated that approximately 31% of the world population has blood pressure levels ≥ 140/90 mmHg or uses antihypertensive medication. Hypertension is also the main risk factor with an independent, linear, and continuous association for cardiovascular diseases. Cardiovascular diseases, in turn, are the leading cause of death, hospitalizations, and outpatient care worldwide, including in developing countries such as Brazil. With aging, hypertension becomes an even more significant […]

Abstract Background: Cardiovascular disease (CVD) is the leading cause of death worldwide, including among physicians. Professional peculiarities increase cardiovascular risk in this population, making it relevant to analyze mortality in the medical population (MPop) and non-medical population (NMPop). Objectives: To compare the CVD mortality coefficient (MC) in between MPop and NMPop in Brazil by analyzing the epidemiological profile and the main causes of deaths from CVD. Methods: Time-series study with data obtained from the Mortality Information System of the Federal […]

We hardly ask ourselves what we will die from. The certainty of this fact can even pass through our thoughts, but it always seems to us something far away and impossible to predict. We can know the causes of death of our fellow human beings to try to predict our death and perhaps use measures to postpone it, since it is impossible to avoid. Societies need to know their numbers, how many we are, how many are born, how many […]

Abstract Background: The use of combined oral contraceptives (COC) is a risk factor for atherosclerotic disease, and physical exercise can minimize this condition. Objective: To verify if high intensity interval training (HIIT) promotes changes in the lipid and inflammatory profile of women using COC. Methods: Sequential crossover study with women aged 20-30 years, classified as irregularly active by the international physical activity questionnaire (IPAQ), when using COC. A physical-clinical assessment was performed with anthropometric measurements, VO2max, and analysis of lipid […]

The concept of oral contraception, historically, was supposed to enable control of unwanted pregnancies and facilitate family planning for women of reproductive age in an elegant fashion for everyone needing it. However, the influence of different prescriptions on women’s health during active use, as well as later on in life – beyond the quintessential fear of thromboses lay women worldwide have – has not been studied extensively or meticulously, despite the widespread use. Also, with some countries recently starting to […]

Abstract Background: Due to its poor prognosis and mortality rates, heart failure (HF) has been recognized as a malignant condition, comparable to some cancers in developed countries. Objectives: To compare mortality from HF and prevalent cancers using data from a nationwide database in Brazil. Methods: This was a descriptive, cross-sectional study using secondary data obtained from Brazilian administrative databases of death records and hospitalization claims maintained by the Ministry of Health. Data were analyzed according to main diagnosis, year of […]

Cardiovascular disease and cancer are the leading causes of mortality in most high-income countries around the globe. It is estimated by the Brazilian Ministry of Health that circulatory diseases and cancer are the leading causes of mortality in patients over 50 years of age, which makes them the main public health concerns in absolute numbers. This is not only true in treatment-related costs, but also in terms of social harm imposed on an economically productive population and the health system […]

Abstract Background: Air pollution and sex independently affect cardiac autonomic control, which can be assessed by heart rate variability (HRV). The research hypothesis is that individuals exposed to low concentrations of pollution have higher cardiac autonomic modulation compared to those exposed to high concentrations and that women have better cardiac autonomic control than men. Objective: To analyze the impact of exposure to air pollutants, specifically smoke, and sex on HRV in healthy young people exposed to different concentrations of pollution […]

Abstract Background: Although electrical and structural remodeling has been recognized to be important in the pathophysiology of atrial fibrillation, the mechanisms underlying remodeling process are unknown. There has been increasing interest in the involvement of inflammatory molecules and adipokines released from the epicardial fat tissue in the pathophysiology of atrial fibrillation. Objectives: In our study, we aimed to investigate the relationship of atrial fibrillation with increased epicardial adipose tissue, inflammatory molecules released from this tissue and omentin. Methods: Thirty-six patients […]

Abstract The prevalence of depression varies from 1 to 17% in different geographic regions, and its incidence is 70% higher in women than men. Today, depression affects more than 300 million people worldwide, affecting twice as many women from adolescence to adulthood. In addition to this earlier onset, depression in women tends to be more severe. Cardiovascular disease and depression are chronic diseases that have a major impact on cardiovascular and all-cause morbidity and mortality, with evidence of a two-way […]

Abstract Ischemic strokes secondary to occlusion of large vessels have been described in patients with COVID-19. Also, venous thrombosis and pulmonary thromboembolism have been related to the disease. Vascular occlusion may be associated with a prothrombotic state due to COVID-19-related coagulopathy and endotheliopathy. Intracranial hemorrhagic lesions can additionally be seen in these patients. The causative mechanism of hemorrhage could be associated with anticoagulant therapy or factors such as coagulopathy and endotheliopathy. We report on cases of ischemic, thrombotic, and hemorrhagic […]

Introduction Takotsubo cardiomyopathy (TC), also known as broken heart syndrome or stress-induced cardiomyopathy, was primarily described in Japan in 1990, is named after its morphological similarity to the vase used by Asian people to catch octopuses, which has a rounded bottom and a narrow bottleneck. This condition is characterized by transient left ventricular (LV) systolic dysfunction, commonly preceded by physical or emotional stress, mimicking the presentation of acute myocardial infarction. In the present article, we describe a case of TC […]
