Introduction Resistant hypertension (RH) is directly related to increased mortality, severe renal changes, and cardiac and cerebrovascular diseases, due to lack of adequate drug treatment. Cardiovascular disease mortality increases progressively and linearly as BP increases, whereas BP lowering is associated with significantly reduced risks. – Increased sympathetic tone in renal arteries is one of the major components of RH, and catheters have been developed using several technologies which allow for radiofrequency ablation (RA) and blood pressure (BP) reduction. The discussions […]

Background: Arterial stiffness (AS) is recognized as an important and independent risk factor for cardiovascular diseases (CVD). Objective: This study was aimed at identifying the main determinants of AS in the elderly. Design and Methods: This was an observational, cross-sectional study of elderly participants. Blood pressure (BP) and parameters of arterial function were measured using a validated device. Clinical and demographic data, global cardiovascular risk, health-related quality of life, dietary profile and cognition data were evaluated. Blood samples were collected […]

The World Health Organization declared that the new coronavirus outbreak is a public health emergency of pandemic proportions. The outbreak has caused various governments to take protective measures such as lockdown of cities, travel bans, prohibition of group gatherings and public events, and social distancing. Many health and exercise training facilities were closed, as well as cardiac rehabilitation services. These restrictions are disrupting people’s daily activities. Although staying at home can contain virus spread, it will certainly reduce regular physical […]

The sedentarism pandemic The WHO recommends that adults aged 18 years and older should accumulate at least 150 minutes of moderate-intensity aerobic activity, 75 minutes of vigorous-intensity aerobic activity, or a combination of both per week. People who do not meet these requirements are considered sedentary. The health benefits of physical exercise include lower risks of cardiovascular disease, hypertension, diabetes, obesity, dementia and breast and colon cancer. – Despite all these benefits, sedentarism is a pandemic, affecting 27.5% of people […]

Currently, the association between obesity and heart failure (HF) is increasingly known. Patients with advanced obesity who suffer from HF without an identifiable cause can be diagnosed as having obesity-associated cardiomyopathy. Although data suggest that obesity may reduce mortality in HF, weight loss, especially in the presence of morbid obesity, reduces symptoms and improves the quality of life of those patients. Bariatric surgery is the major treatment available for sustained weight loss in morbid obesity. Observational studies have demonstrated an […]

Abstract The primary goal of coronary artery bypass grafting is to achieve complete revascularization with grafts that will remain patent throughout the patient’s lifetime. This study investigated the association between bypass graft patency and comorbidity burden determined by Charlson comorbidity index (CCI) among patients with previous bypass operation who underwent a control angiography. One-hundred and two patients who had undergone CABG in the past were included to the study. Critical stenosis was defined as 50% or greater coronary luminal obstruction […]

Abstract Heart failure is one of the most important and challenging public health problems of the 21st century and is associated with hard outcomes, such as death and hospitalization. New treatments for heart failure, despite the decrease in mortality, have not contributed to the decrease in hospitalization rates. Patients admitted with heart failure have a high event rate (> 50%) with a mortality rate between 10 and 15% and a rehospitalization rate within 6 months after discharge of 30 to […]
