Development and validation of the Brazilian Portuguese version of the Cardiac Rehabilitation Barriers Scale.
Cardiovascular diseases show high incidence and prevalence in Brazil; however, participation in Cardiac Rehabilitation (CR) is limited and has been poorly investigated in the country. The Cardiac Rehabilitation Barriers Scale (CRBS) was developed to assess the barriers to participation and adherence to CR. ⋯ The Brazilian Portuguese version of CRBS has shown adequate validity and reliability, which supports its use in future studies.

Emergency service admission time and in-hospital mortality in acute coronary syndrome.
The relationship between admission time to an emergency service and in-hospital outcomes in acute coronary syndrome (ACS) is controversial. Admission during off-hours would be associated with worse prognosis. ⋯ Prolonged length of hospital stay and in-hospital mortality in ACS patients do not depend on admission time.

Review Meta Analysis Comparative StudyOn-pump versus off-pump coronary-artery bypass surgery: a meta-analysis.
There are controversies about the possible benefits of off pump coronary artery bypass grafting (OPCABG) compared to on-pump coronary artery bypass grafting (ONCABG). For a better perspective on this important issue, we performed a meta-analysis of randomized controlled trials, comparing the two techniques. The objective of this study was to verify which technique applied in Coronary Artery Bypass Surgery, OPCABG or ONCABG, provides better results through a meta-analysis of published randomized trials comparing the two techniques. ⋯ Regarding mortality, a reduction of 18% in the risk of cardiovascular mortality (OR: 0.82, 95%CI: 0.70 to 0.98, p = 0.03) and 27% in the risk of stroke postoperatively (OR: 0.73, 95%CI: 0.63 to 0.85, p = 0.0001) were observed, both in favor of OPCABG. Concerning the occurrence of complications associated with the procedure, no significant differences were found between the two surgical techniques, particularly with regard to the occurrence of kidney complications (OR: 0.97, 95%CI: 0.84-1.14, p = 0, 74) and sepsis (OR 0.98, 95%CI: 0.64-1.51, p = 0.93, respectively). Off-pump CABG significantly reduces the occurrence of major cardiovascular events (mortality and CVA) compared to on-pump CABG surgery.

Comparative StudyComparison of assessment methods of cardiac vagal modulation.
Several methods have been used to assess cardiac vagal modulation, but there are gaps regarding the association and accuracy of these methods. ⋯ HRV and RSA generated partially redundant results in healthy subjects and in patients with coronary artery disease, while the T4s generated results that were complementary to HRV and RSA in healthy subjects. In addition, RSA and T4s methods were more accurate when discriminating cardiac vagal modulation between healthy subjects and patients with coronary artery disease, when compared to HRV.
