Electrocardiography scar quantification correlates with scar size of hypertrophic cardiomyopathy seen by multidetector computed tomography.

Background: Hypertrophic cardiomyopathy (HCM), a genetically transmitted disease, is the most common genetic cardiovascular disease. Current strategies to stratify risk are expensive and concentrated in wealthy centers. Twelve-lead electrocardiography (ECG) is inexpensive, universally available, and can be readily used for Selvester QRS scoring, which estimates scar size.

CKD-EPI versus Cockcroft-Gault formula for predicting contrast-induced nephropathy following percutaneous coronary intervention in patients without significant renal impairment.

Introduction: Individuals with glomerular filtration rate (GFR) ≥60 ml/min/1.73 m estimated by the Cockcroft-Gault formula (CG) who undergo percutaneous coronary intervention (PCI) frequently develop contrast-induced nephropathy (CIN). This study aimed to assess whether individuals with significant renal impairment assessed by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, but not by CG, more often develop CIN following PCI than those without renal impairment by either formula.

Quality of life of hemodialysis patients in a Brazilian Public Hospital in Belém - Pará.

Introduction: End-stage chronic kidney disease (CKD) requiring dialysis affects the quality of life sometimes more severely than other chronic diseases, such as rheumatoid arthritis, heart failure, coronary artery disease, and chronic obstructive pulmonary disease, exerting a negative effect on the energy and vitality levels, limiting social interactions, and hindering psychic health.

Objective: To evaluate the quality of life of patients with CKD on hemodialysis in a public Brazilian Amazonian hospital.

Methods: Data were collected through interview based on the Brazilian version of the SF-36 questionnaire.
