The authors retrospectively analyzed the STS datablase for utilization of bilateral mammary artery (BIMA) grafts in patients considered at low risk for BIMA use. This group of patients were compared to a propensity matched group of single mammary artery graft (SIMA) patients.

Retrospective cross-sectional cohort study using 5 years of Medicare benficiary data to determine whether post discharge mortality varies by time-to-readmission. Two of the three operations analyzed were lung resection (n=101,092) and coronary artery bypass grafting (CABG) (n=484,260).

Using propensity score matching techniques, outcomes and costs for robotic cardiac surgery were compared to open cardiac surgery using data from the Nationwide Inpatient Sample. Robotic surgery was more expensive ($39,030 vs $36,340) but was associated with a shorter length of stay (5 vs 6 days), lower mortality (1.0% vs 1.9%), and lower overall com

The good news continues regarding chocolate consumption! A study involving nearly 21,000 individuals with a median follow-up of nearly 12 years correlated cardiovascular disease with quintiles of chocolate consumption. The lowest quintile was associated with a 50% higher risk of coronary heart disease and a similar increase in stroke incidence.

This Swedish study was a retrospective review over a 20-year time period that compared survival after out-of-hospital cardiac arrest between those receiving bystander CPR prior to EMS arrival and those not receiving such. CPR before the arrival of EMS was associated with an increased 30-d survival rate (odds ratio 2.15; 95% CI 1.88-2.45).

240 high risk patients undergoing cardiac surgery were randomized to remote ischemic preconditioning (3 5-min cycles of single upper extremity ischemia after anesthetic induction) or sham. Preconditioning reduced the incidence of acute kidney injury by one-third and the need for renal replacement therapy by two-thirds. These results were associated

In this manuscript, the authors describe their findings of an extensive literature review of 12 mostly observational, retrospective studies evaluating the use of dual antiplatelet therapy (DAPT) in patients after CABG. They conclude that there is no clear consensus regarding the use DAPT in patients undergoing CABG.

Patients with LV dysfunction who underwent complete surgical revascularization were evaluated with angiograms, echo, and MR (evaluating late vascular enhancement with contrast). About 70% of dysfunctional segments segments demonstrated improved wall motion after revascularization, and this was unrelated to the degree of late vascular enhancement evi

This video demonstrates total arterial complete revascularization with bilateral internal mammary artery and mitral valve replacement in a 62-year-old male patient.

In this manuscript the authors describe their findings in a meta-analysis of 12 randomized placebo-controlled clinical trials involving 2,980 patients undergoing isolated CABG. They found that statin therapy, particularly atorvastatin, initiated before CABG, was associated with a 58% reduction in the risk of postoperative AF.
