Diabetes drug Liraglutide reduces cardiovascular events and mortality

Type II diabetes, an epidemic fuelled by an unrelenting rise in obesity and sedentary behaviors, is a major risk factor for both micro- and macrovascular disease. An array of new treatments have recently come to trial with the aim of improving glycemic control and reducing disease complications. But lingering doubts remain regarding the cardiovascular implications […]

Long-term survival benefit for CABG in ischemic cardiomyopathy

The STICH trial asked the important question whether CABG in patients with severe ischemic cardiomyopathy would provide a survival advantage over contemporary medical therapy alone. Reporting 5-year data in 2011, the study reported no significant difference but did demonstrate a tantalizing divergence in survival graphs between 2 and 5 years, which appeared to be increasing […]

Transcatheter aortic valve implantation in intermediate risk patients

Transcatheter aortic valve implantation (TAVI) has had a major impact on both morbidity and mortality in high-risk and inoperable patients with severe aortic stenosis. Robust evidence has supported widespread adoption in this patient group but uncertainty exists as to whether TAVI may also achieve clinical equipoise with surgical aortic valve replacement (AVR)  in lower risk […]

Pre-operative aspirin does not influence CABG outcomes.

Aspirin is a common therapy for risk reduction among patients with coronary artery disease.  However, among patients undergoing coronary artery bypass surgery, the benefits of aspirin on the risk of myocardial infarction and stroke may be outweighed by perioperative bleeding risk.   To address this question, the ATACAS trial randomized 2100 patients to either receive 100 […]

Mailing Nicotine Patches Improves Smoking Abstinence

Although clinical trials of nicotine replacement therapy (NRT) have consistently demonstrated higher rates of smoking cessation, the effectiveness of NRT may be lower in real-world settings, especially in the absence of behavioral support.  Accordingly, there is a need for randomized clinical trials to evaluate the effectiveness of NRT alone.  Cunningham et al conducted a randomized […]

Statin does not protect against acute kidney injury following cardiac surgery

Although statins affect mechanisms that lead to postoperative acute kidney injury (AKI), observational studies have failed to demonstrate a consistent effect of statin therapy on the risk of AKI after cardiac surgery. The Statin AKI Cardiac Surgery randomized control trial sought to determine if high-dose, short-term atorvastatin reduced the risk of AKI following cardiac surgery.  […]

TAVR adoption and outcomes in German national practice

The advent of transcatheter aortic valve replacement (TAVR) has afforded an alternative to surgical aortic valve replacement (SAVR) for high-risk or non-operative candidates for aortic valve surgery.  However, the adoption of TAVR may not be limited to the patient population for who the procedure has studied and outcomes in routine clinical practice may not reflect […]

Effect of caloric restriction on heart failure with preserved ejection fraction

Therapies that improve outcomes are lacking for heart failure with preserved ejection fraction (HFpEF). The impact of exercise and diet interventions on HFpEF patients has not been studied.  In this single center study of 100 patients,  the effect of caloric restriction (~400 kcal/day) and or aerobic exercise training (3x a week hour long supervised sessions) […]

COURAGE at 15 years

Although PCI improves morbidity and mortality in the context of an acute coronary syndrome, the benefit of PCI in the setting of stable ischemic heart disease appears limited to symptom relief.  This was best demonstrated by the COURAGE trial that randomized 2287 patients with stable angina to either intensive medical therapy alone or medical therapy […]
