Dear Editor, I have read with interest the study titled “The Predictive Value of the Inflammatory Prognostic Index for Detecting No-Reflow in ST-Elevation Myocardial Infarction Patients”, published in your journal. I would like to contribute to the study by providing some insights. […]

Dear Editor, We read the article published by Negretto et al. with great interest. The authors reported testosterone deficiency is present in 26.3% of the patients with arterial hypertension and testosterone levels decrease by increasing age and body mass index. The role of testosterone in hypertension and factors affecting both arterial blood pressure and testosterone level are interesting and overlooked topics in daily practice. […]

Dear Editor, I read with great interest the article entitled “Addition of High-Sensitivity Troponin to Perioperative Risk Assessment Improves the Predictive Ability of Death in Non-Cardiac Surgery Patients” by Gomes et al. the prevalence of myocardial injury is higher in high-risk patients, including those with cardiovascular, surgical, and clinical risks. They also reported that the occurrence of non-cardiac surgical myocardial injury in the population not considered high-risk cannot be overlooked and leads to high mortality in this population. In long-term […]

I read with interest the study by Ramos et al. on the ” Prognostic Value of Preoperative Electrocardiogram in Low-Risk Patients Undergoing Surgical Intervention and General Anesthesia”. The authors’ efforts to clarify the predictive efficacy of preoperative electrocardiography (ECG) in a population that appears to have a low-risk profile are meritorious. Nonetheless, I harbor concerns regarding the employed methodology, which may potentially impact the study’s findings. Directly examining the hypothesis that an abnormal ECG can serve as a predictor of […]

The recent update on the guideline for the management of cardiomyopathy in Chagas disease brings several significant improvements. The evidence on etiological stroke investigation, management of secondary prophylaxis, and overall epidemiology are all of vital importance for clinicians to improve treatment for these patients. One concern that arises from the guideline pertains to the indication of oral anticoagulation, particularly the suggestion that any previous ischemic stroke would warrant such intervention. […]

Cardiac involvement in Chagas Disease (CD) represents the most severe form of the disease, occurring in 30 to 40% of infected patients. Patients with heart failure of chagasic origin are often refractory to drug treatment, requiring assessment of the need for heart transplantation (CT). After carrying out the CT, it is necessary patient’s immunosuppression to ensure a greater chance of graft acceptance and vitality, on the other hand, immunosuppression is a contributing factor to CD relapse, which could directly compromise […]

In the last decades, cardiovascular diseases have become the leading cause of pregnancy-related deaths. This is due to the increasing prevalence of risk factors for cardiovascular disease in young women, late pregnancy planning, and the increasing number of cases of adult congenital heart disease., In Brazil, it is estimated that 4% of pregnancies occur in women with heart disease, which represents the main non-obstetric cause of maternal death. In addition, the preventable and probably preventable causes of deaths reach up […]

Dear Editor, I have read the manuscript comparing the hemodynamic measurements of pulmonary vascular bed obtained from transthoracic echocardiography and invasive right heart catheterization with great interest. The authors reported that although the results of both diagnostic interventions correlate with each other, nearly half of echocardiographic measurements of systolic pulmonary artery pressure and right atrial pressure are accurate. […]

Dear Editor, The study published by Demirci et al. brings up an interesting and current discussion by evaluating the effect of intermittent fasting (IF) on blood pressure, the renin-angiotensin system (RAS), and the autonomic nervous system (ANS) in hypertensive patients using 24-hour ambulatory blood pressure monitoring (ABPM), Holter electrocardiogram, serum levels of Ang-I and Ang-II and ACE activity before and after IF. Among the findings was a notable reduction in blood pressure in patients undergoing IF, as well as a […]

To the Editor, We carefully read the article entitled: “The relationship between the uric acid/albumin ratio and the carotid intima-media thickness in patients with hypertension“, whose objective was to investigate the association of the uric acid/albumin ratio (UAR) and carotid intima-media thickness (CIMT) in hypertensive patients. Although the present study demonstrated a significant correlation between UAR and CIMT, with UAR showing greater discriminatory capacity for increased CIMT values than uric acid and albumin alone and than the other inflammatory markers […]
