Prevalence and Predictors of COVID-19 Long-Term Symptoms: A Cohort Study from the Amazon Basin.

It remains unclear whether a previous history of tropical infectious diseases and a second SARS-COV-2 infection may influence the likelihood of later symptoms. In this prospective cohort study, individuals infected with SARS-CoV-2 were followed up by telephone shortly after diagnosis of COVID-19 and again 12 months later. Poisson regression was used to identify the predictors of the highest number of symptoms in the post-COVID-19 syndrome.

Determinants and prognostic value of in-hospital infection in patients waiting for permanent pacemaker implantation.

Background: In-hospital delays in permanent cardiac pacemaker (PPM) implantation are common and may result in in-hospital infection among patients waiting for PPM implantation (pre-PPM-HI). This study investigated the predictors and prognostic impact of these events.

Methods: We retrospectively evaluated 905 consecutive patients (68.

Sex- and Age-Related Impact of the COVID-19 Pandemic on Emergency Department Visits for Chest Pain in Curitiba, Brazil.

Background: Women have higher mortality from acute coronary syndrome (ACS) compared with men. Women may hesitate to search for emergency care when experiencing chest pain, which delays treatment.

Objective: Our aim was to evaluate the changes in emergency visits for chest pain according to sex and age during the COVID-19 pandemic period compared with previous years.

Long-term results of the Ross operation in rheumatic valve disease.

Aims: The aim of this study was to evaluate the impact of rheumatic heart disease (RHD) on the long-term outcomes of the Ross operation when compared to patients with bicuspid aortic valves (BAV).

Short- and Midterm Adherence to Platelet P2Y12 Receptor Inhibitors After Percutaneous Coronary Intervention With Drug-Eluting Stents.

Introduction/objectives: In patients who have undergone recent percutaneous coronary intervention (PCI), poor adhesion to antiplatelet agents may increase the risk of stent thrombosis and death. We aimed to investigate the adherence to different P2Y12 receptor inhibitors after PCI with drug-eluting stent in stable and unstable patients and to evaluate the factors associated with low adherence.

Method: In a prospective study conducted between 2014 and 2018, the 8-item Morisky scale was applied at 30 days and 6 months post-PCI to measure P2Y12 receptor inhibitors adherence.

Radiation exposure after myocardial perfusion imaging with Cadmium-Zinc-Telluride camera versus conventional camera.

Background: Patient exposure to radiation during the management of coronary heart disease (CHD) can be reduced with more efficient technologies in nuclear medicine, such as the Cadmium-Zinc-Telluride (CZT) gamma-camera for myocardial perfusion imaging (MPI) studies. However, it has been suggested that CZT has lower specificity, which might lead to more downstream radiological procedures, particularly among obese individuals.

Methods And Results: We evaluated 244 patients with suspected CHD who underwent CZT-SPECT and matched 1:1 according to sex, age, and body mass index (BMI) with those undergoing MPI study with the Anger gamma-camera (Anger-SPECT).
