Physical activity is associated with a lower prevalence of depressive symptoms in cardiac patients. However, the benefits of physical activity on depression perioperatively are unknown. We sought to identify independent parameters associated with depression in patients undergoing cardiac surgery. ⋯ Up to 40% of patients are depressed after cardiac surgery. Preoperative depression and postoperative stressful events were the strongest independent associations postoperatively. Physical inactivity was associated with preoperative depression and new depression 6 months postoperatively.

The junction between the left brachiocephalic vein and the superior vena cava is a high-risk region during lead extraction. Venous laceration with hemodynamic collapse is the most feared complication arising in this region, but arteriovenous fistula formation after excimer laser extraction also has been reported. ⋯ A continuous murmur was heard near the extraction site and invasive angiography demonstrated a left internal mammary artery to the brachiocephalic vein fistula, which was coiled. A new continuous murmur after lead extraction is the hallmark of this rare complication.

The Canadian Heart Health Strategy and Action Plan recommended that the Canadian Cardiovascular Society (CCS) lead the development of pan-Canadian data definitions and quality indicators (QIs) for evaluating cardiovascular care in Canada. In response to this recommendation, the CCS developed and adopted a standardized QI development methodology. This report provides a brief overview of the CCS "Best Practices" for developing pan-Canadian cardiovascular QIs. ⋯ It also describes the CCS QI approval process and addresses knowledge translation. Adoption of a standardized methodology for QI development will improve the quality, completeness, acceptability, and usability of pan-Canadian cardiovascular QIs developed by the CCS. Public release of the QI definitions and related performance data might help improve patient care quality and outcomes.

Review Practice Guideline
Focused 2012 update of the Canadian Cardiovascular Society guidelines for the use of antiplatelet therapy.
The initial 2010 Canadian Cardiovascular Society (CCS) Guidelines for the Use of Antiplatelet Therapy in the Outpatient Setting were published in May 2011. As part of a planned re-evaluation within 2 years, we conducted an extensive literature search encompassing all topics included in the 2010 CCS Guidelines, and concluded that there were sufficient new data to merit revisiting the guidance on antiplatelet therapy for secondary prevention in the first year after acute coronary syndrome (ACS), percutaneous coronary intervention, or coronary artery bypass grafting, and the interaction between clopidogrel and proton pump inhibitors. ⋯ For non-ACS stented patients, we recommend acetylsalicylic acid/clopidogrel for 1 year, with at least 1 month of therapy for bare-metal stent patients and 3 months for drug-eluting stent patients unable to tolerate year-long double therapy. We also consider therapy for patients with a history of stent thrombosis, the indications for longer-term treatment, discontinuation timing preoperatively, indications for changing agents, the management of antiplatelet therapy before and after bypass surgery, and use/selection of proton pump inhibitors along with antiplatelet agents.

Randomized Controlled Trial
Randomized trial of Nordic walking in patients with moderate to severe heart failure.
Patients with heart failure are a growing population within cardiac rehabilitation. The purpose of this study was to compare, through a single-centre, parallel-group, randomized controlled trial, the effects of Nordic walking and standard cardiac rehabilitation care on functional capacity and other outcomes in patients with moderate to severe heart failure. ⋯ Nordic walking was superior to standard cardiac rehabilitation care in improving functional capacity and other important outcomes in patients with heart failure. This exercise modality is a promising alternative for this population.
