Paclitaxel-Coated Balloon for the Management of In-Stent Coronary Restenosis: An Updated Meta-Analysis and Trial Sequential Analysis.

Background: Drug-coated balloons present a potentially advantageous therapeutic approach for managing coronary in-stent restenosis (ISR). However, the comparative benefits of paclitaxel-coated balloons (PCBs) over uncoated balloons (UCBs) remain unclear.

Aims: We conducted a systematic review and meta-analysis to evaluate and compare the clinical outcomes of patients treated with PCBs and UCBs.

Frequency, Regional Variation, and Predictors of Undetermined Cause of Death in Cardiometabolic Clinical Trials: A Pooled Analysis of 9259 Deaths in 9 Trials.

Background: Modern cardiometabolic clinical trials often include cardiovascular death as a component of a composite primary outcome, requiring central adjudication by a clinical events committee to classify cause of death. However, sometimes the cause of death cannot be determined from available data. The US Food and Drug Administration has indicated that this circumstance should occur only rarely, but its prevalence has not been formally assessed.

Is waist-to-height ratio the best predictive indicator of hypertension incidence? A cohort study.

Background: The best anthropometric indicator to verify the association between obesity and hypertension (HTN) has not been established. We conducted this study to evaluate and compare the discriminatory power of waist-to-height ratio (WHtR) in relation to body mass index (BMI) and waist circumference (WC) in predicting HTN after 13 years of follow-up.

Methods: This study was an observational prospective cohort study performed in the city of Firminópolis, in Brazilian's midwest.

Predictors of overweight/obesity in a Brazilian cohort after 13 years of follow-up.

Background: Obesity is a chronic complex disease with an increasing prevalence around the world. Prospective studies in adult cohorts are needed to provide information about predictors of new-onset overweight/obesity on population-based levels. The aim of this study was to identify factors associated with the risk of an adult individual become overweight/obese after 13 years of follow-up.

Sympathetic nervous activity in patients with acute coronary syndrome: a comparative study of inflammatory biomarkers.

Previous studies have shown that both sympathetic hyperactivity and enhanced inflammatory responses are associated with poor outcomes in patients with acute coronary syndrome (ACS). Whether there is a correlation between these two characteristics remains unclear. Thirty-four patients with uncomplicated ACS were evaluated; their mean age was 51.

Neurovascular control during exercise in acute coronary syndrome patients with Gln27Glu polymorphism of β2-adrenergic receptor.

Background: Gln27Glu (rs1042714) polymorphism of the β2-adrenergic receptor (ADRB2) has been association with cardiovascular functionality in healthy subjects. However, it is unknown whether the presence of the ADRB2 Gln27Glu polymorphism influences neurovascular responses during exercise in patients with acute coronary syndromes (ACS). We tested the hypothesis that patients with ACS homozygous for the Gln allele would have increased muscle sympathetic nerve activity (MSNA) responses and decreased forearm vascular conductance (FVC) responses during exercise compared with patients carrying the Glu allele (Gln27Glu and Glu27Glu).

The bleeding risk score as a mortality predictor in patients with acute coronary syndrome.

Background: It is well known that the occurrence of bleeding increases in-hospital mortality in patients with acute coronary syndromes (ACS), and there is a good correlation between bleeding risk scores and bleeding incidence. However, the role of bleeding risk score as mortality predictor is poorly studied.

Objective: The main purpose of this paper was to analyze the role of bleeding risk score as in-hospital mortality predictor in a cohort of patients with ACS treated in a single cardiology tertiary center.

In patients with acute myocardial infarction, the impact of hyperglycemia as a risk factor for mortality is not homogeneous across age-groups.

Objective: To assess the impact of hyperglycemia in different age-groups of patients with acute myocardial infarction (AMI).

Research Design And Methods: A total of 2,027 patients with AMI were categorized into one of five age-groups: <50 years (n = 301), ≥50 and <60 (n = 477), ≥60 and <70 (n = 545), ≥70 and <80 (n = 495), and ≥80 years (n = 209). Hyperglycemia was defined as initial glucose ≥115 mg/dL.

[Arterial hypertension and its correlation with some risk factors in a small brazilian town].

Background: arterial hypertension (AH) is a health problem that affects a large number of undiagnosed or inadequately treated hypertensive individuals and presents a high rate of treatment nonadherence.

Objective: to estimate the prevalence of AH and its correlation with some cardiovascular risk factors among the adult population of the town of Firminopolis, state of Goiás, Brazil.

Methods: descriptive, observational and cross-sectional population-based study of a simple random sample (age > 18 years): standardized questionnaires with blood pressure (BP) measurements (AH criterion: BP > 140 x 90 mmHg), weight, height, Body Mass Index (BMI) and waist circumference (WC).

[Hypertension and its association to anthropometric indexes in adults from a small city ln Brazil].

Objective: Estimate the prevalence of Arterial Hypertension (AH) and its association with Body Mass Index (BMI) and Abdominal Circumference (AC) in the adult population from the city of Firminópolis, in the state of Goiás, Brazil.

Methods: Descriptive, observational, cross sectional population-based study substantiated by a home survey of a simple random sample (> or = 18 years old). The study evaluated 1168 individuals.

Analysis of heart rate variability in hypertensive patients before and after treatment with angiotensin II-converting enzyme inhibitors.

Objective: To compare heart rate variability in normotensive and hypertensive individuals and to observe the behavior of the autonomic nervous system after treatment with angiotensin II-converting enzyme inhibitors.

Method: The study comprised 286 patients diagnosed with arterial hypertension (AH) for the first time and divided into 4 groups according to diastolic blood pressure (DBP) levels: group A -- DBP<90 mmHg; group B -- DBP 90-99 mmHg; group C -- DBP 100-109 mmHg; group D -- DBP>110 mmHg. Group A (110 healthy individuals) and group C (79 patients with moderate AH) underwent 24-hour Holter-ECG with analysis of heart rate variability in time domain (TD) and frequency domain (FD).
