Syntax Score and Major Adverse Cardiac Events in Patients with Suspected Coronary Artery Disease: Results from a Cohort Study in a University-Affiliated Hospital in Southern Brazil.

Background:: The importance of coronary anatomy in predicting cardiovascular events is well known. The use of traditional anatomical scores in routine angiography, however, has not been incorporated to clinical practice. SYNTAX score (SXscore) is a scoring system that estimates the anatomical extent of coronary artery disease (CAD).

Continuous positive airway pressure reduces blood pressure in patients with obstructive sleep apnea; a systematic review and meta-analysis with 1000 patients.

Background: Obstructive sleep apnea (OSA) may lead to the development of hypertension and therapy with continuous positive airway pressure (CPAP) can promote reduction in blood pressure.

Objective: The objective of this study is to review systematically the effects of CPAP on blood pressure in patients with OSA.

Methods: The search was conducted in the following databases, from their beginning until February 2013: MEDLINE, Embase, Cochrane CENTRAL, Lilacs and PEDro.

Association between hypertension and musculoskeletal complaints: a population-based study.

Objective: To investigate the association between hypertension and musculoskeletal complaints among men and women selected by a population-based sample.

Methods: A cross-sectional study, with participants selected using a multistage sampling procedure and interviewed at home, was conducted to investigate the association between hypertension and musculoskeletal complaints. Hypertension was defined by the average of four measurements of blood pressure (BP) at least 140/90  mmHg or use of BP-lowering drugs.
