An international group of distinguished researchers says newly examined, unpublished genetic data provide final proof that homocysteine does not cause coronary heart disease and therefore reducing levels of this amino acid with folate would have no effect. But another expert disagrees.

Six of seven guideline-recommended HF therapies lower mortality at two years
Results of a new study reinforce the importance of adhering to the clinical guidelines, investigators say, stressing the implications of their findings: there is nowhere else in cardiovascular medicine where clinicians can achieve incremental reductions in the range of 80% to 90%.

Fidelis failures climb: "Strongly consider" replacement at ICD change-out
It may be a good time to replace patients' Medtronic Sprint Fidelis leads, which were recalled due to an increased fracture risk, if they are getting new ICD generators anyway—even if the Fidelis hasn't shown signs of trouble, a group recommends.

Generalists need education on HF treatment
A unique study trying to drill down into why cardiologists seem to gain better outcomes than generalists when treating heart failure has identified a number of reasons that this is the case. But generalists—who treat the majority of HF—have to deal with older and sicker patients, confounding the issue. The authors hope the work will act as a catalyst to improve HF care.

SWITCH III: Bivalirudin is as safe as heparin after fondaparinux in PCI patients
Recent studies have shown that ACS patients on fondaparinux prior to PCI should switch to another anticoagulant prior to the procedure to avoid thrombus. The SWITCH III trial compares bivalirudin and unfractionated heparin in a small group of these patients.

KEEP: Focus on CKD patients with highest SBP
A new, contemporary study in real-world patients with chronic kidney disease finds that those with systolic BPs of 140 mm Hg and higher are at the greatest risk of developing end-stage renal disease. Hence the current "goal" in CKD patients of 130 mm Hg should be revised upward, say the authors, making the target easier to achieve and allowing physicians to focus on other aspects of care.

A new analysis of the PLATO study has found that use of a proton-pump inhibitor was independently associated with a higher rate of cardiovascular events but that this was apparent in both the ticagrelor and clopidogrel arms.

Excessive food intake, rather than the mix of protein, fat, and carbohydrates, has been implicated in causing obesity and is key in treating it.

RESPECT PFO/stroke trial completes enrollment
After eight years of sluggish patient accrual, the RESPECT trial looking at the Amplatzer device for the prevention of cryptogenic stroke has finally collected enough events for the trial to be stopped.

Public Citizen requests recall of the Wingspan stent
A consumer-advocacy group argues that the Wingspan Stent System provides less benefit and causes more harm than aggressive medical treatment alone.

BRCA1 cancer gene affects cardiac function
Canadian researchers have discovered that the BRCA1 gene is implicated in cardiac function, at least in mice. The findings may also have implications for cancer sufferers who have mutations in this gene: they may be at increased risk of heart disease and more likely to suffer cardiotoxicity from chemotherapy.

Rivaroxaban filed for ACS in US and EU
The factor Xa inhibitor rivaroxaban has been filed for approval for the additional indication of secondary prevention in acute coronary syndrome in both the US and EU.

Type 2 diabetes adds risk to tissue valves
Type 2 diabetes is a known determinant of degeneration of both native and prosthetic valve implants, so a group of Italian researchers investigated whether bioprosthetic valves also degenerate faster in diabetic patients vs nondiabetic patients.

US leads in shorter hospital stays, early readmission after STEMI
Patients with ST-segment-elevation MI were more likely to be hospitalized again within a month if they had been treated in the US, and American patients had the shortest initial hospitalization, in a retrospective study of data from an international trial. The work identifies national differences in this measure of care—30-day-readmission—and it should help guide future investigations, the authors say.

Bariatric surgery reduces CV events, but mechanisms remain a mystery
The latest data from the Swedish Obese Subjects study show that bariatric surgery reduces the risk of cardiovascular events and CV death among obese individuals, compared with usual care. But weight loss is not the reason behind this reduced risk, meaning that guidelines that use BMI to determine who will get such surgery need updating, say the authors and an editorialist.

Enoxaparin prophylaxis doesn't cut mortality in acute-care setting
Antithrombotic prophylaxis remains important in this group for other reasons, but don't expect it to necessarily prevent death, according to researchers.

Mayo report: It takes docs about 30 TAVIs to achieve proficiency
Two new single-center studies shed light on the contemporary experience with new transcatheter aortic-valve systems. One looks at the "learning curve" required for operators to become proficient with the devices, and the other investigates how patient selection for these procedures has changed over time.

Analysis slams use of clopidogrel loss-of-function gene test; proponents fire back
A new meta-analysis and especially an accompanying editorial argue against current use of CYP2C19 genotyping to define risk of subsequent CV events in patients considered for clopidogrel. Proponents of the test defend its use and describe what they see as flaws in the study.

Troponins at admission and three hours allow MI diagnosis or rule-out
Troponin levels measured using a sensitive or highly sensitive assay can help with early MI rule-out, suggests a study that makes a case supporting the possible approval of the high-sensitivity assay in the US.
