Sickle cell anemia (SCA) is associated to increased cardiac output, normal heart rate (HR), abnormal QT dispersion and lower diastolic blood pressure (DBP). The mechanisms are still unknown. The objective of this study was to test the hypothesis that there is cardiovascular autonomic dysfunction (CAD) in SCA. The secondary objectives were to distinguish the(More)
OBJECTIVE Anatomical and functional assessment of the heart through Doppler and echocardiography in patients with cell anemia (SCA). METHODS Twenty-five patients with SCA and ages ranging from 14 to 45 years were prospectively studied in a comparison with 25 healthy volunteers. All of them underwent clinical and laboratory evaluation and Doppler(More)
The incidence of cancer (CA) has increased globally and radiotherapy (RT) is a vital component in its treatment. Cardiovascular injuries induced by RT in the treatment of thoracic and cervical CA have been causing problems in clinical practice for decades, and are among the most serious adverse effects of radiation experienced by the growing number of(More)
There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high(More)
BACKGROUND Heart failure (HF) is associated with frequent decompensation and admissions to the emergency service. Influenza (INF) and Pneumococcal (pneumonia) vaccinations are recommended in the guidelines, however, respiratory infections are the third leading cause of hospitalization in heart failure. OBJECTIVE To assess the frequency of vaccination(More)
BACKGROUND Metabolic syndrome (MS) is an aggregation of risk factors that increase the incidence of cardiovascular events and diabetes mellitus (DM). Population aging is accompanied by higher prevalence of MS, which varies depending on the population studied and the diagnostic criteria used. OBJECTIVE To determine prevalence of MS in the elderly using(More)
OBJECTIVE To identify left ventricular geometric patterns in hypertensive patients on echocardiography, and to correlate those patterns with casual blood pressure measurements and with the parameters obtained on a 24-hour ambulatory blood pressure monitoring. METHODS We studied sixty hypertensive patients, grouped according to the Joint National Committee(More)
BACKGROUND Planning strategies to prevent heart failure (HF) in developing countries require epidemiologic data in primary care. The purpose of this study was to estimate the prevalence of HF stages and their phenotypes, HF with preserved ejection fraction (HFPEF), and HF with reduced EF (HFREF) and to determine B-type natriuretic peptide (BNP) levels to(More)
BACKGROUND Heart failure (HF) is a major public health issue with implications on health-related quality of life (HRQL). OBJECTIVE To compare HRQL, estimated by the Short-Form Health Survey (SF-36), in patients with and without HF in the community. METHODS Cross-sectional study including 633 consecutive individuals aged 45 years or older, registered in(More)
