Therapy for Pulmonary Arterial Hypertension in Adults: Update of the CHEST Guideline and Expert Panel Report

The January update of an expert panel from the American College of Chest Physicians on the expanding clinical entity of pulmonary hypertension, especially pertinent to the transplant community.

Multiple Versus Single Arterial Coronary Bypass Graft Surgery for Multivessel Disease

The authors reviewed the New York State database. Patients with single arterial grafts were compared to those with multiple arterial grafts. Propensity matching was performed based on 38 baseline characteristics. Twenty percent had multiple arterial grafting. There was no difference at one year but at seven years the multiple arterial graft group had lower mortality and a lower repeat revascularization rate.

Association of Overnight Extubation With Outcomes After Cardiac Surgery in the Intensive Care Unit

Gershengorn and colleagues evaluated the incidence and safety of overnight extubation following coronary artery bypass grafting (CABG), using retrospective data from The Society of Thoracic Surgeons Adult Cardiac Surgery Database. Between 2014 and 2017, 42% of patients undergoing elective CABG had an overnight extubation, a rate that the authors report is similar to patients undergoing other cardiac procedures.

Effects of Intracoronary Nicorandil on Myocardial Microcirculation and Clinical Outcomes in Patients With Acute Myocardial Infarction: A Meta-Analysis of Randomized Controlled Trials

An interesting meta-analysis discouraging perhaps the use of this KATP modulator, especially after surgical revascularization where optimization of serum potassium is generally sought.

Association of Smoking Cessation With Subsequent Risk of Cardiovascular Disease

It's never too late to quit.  Among heavy smokers, smoking cessation resulted in a significantly lower risk of cardiovascular disease within five years of quitting (hazard ratio 0.61), although their risk remained elevated compared to never smokers.
