Report of the American Heart Association (AHA) Scientific Sessions 2016, New Orleans

The American Heart Association (AHA) Scientific Sessions 2016 were held on November 12-16 at the Ernest N. Morial Convention Center, New Orleans, LA. This 5-day event featured cardiovascular clinical practice covering all aspects of basic, clinical, population, and translational content. One of the hot topics at AHA 2016 was precision medicine. The key presentations and highlights from the AHA Scientific Sessions 2016, including "precision medicine" as one of the hot topics, are herein reported.

Report of the American Heart Association (AHA) Scientific Sessions 2015, Orlando

The American Heart Association Scientific Sessions were held in Orlando on November 7-15, 2015. The meeting attracted more than 18,000 participants, including physicians, research scientists, students, and paramedical personnel, from more than 100 countries. Sessions over the 5 days included a comprehensive and unparalleled education delivered via more than 5,000 presentations, with 1,000 invited faculty members and 4,000 abstract presentations from the world leaders in cardiovascular disease. It also displayed the newest cardiovascular technology and resources by more than 200 exhibitors. There were 19 trials scheduled in 6 late-breaking clinical trial sessions. The Systolic Blood Pressure Intervention Trial (SPRINT) aimed to determine the most appropriate targets for the systolic blood pressure among persons without diabetes. A total of 9,361 persons with systolic blood pressure of ≥130 mmHg and an increased cardiovascular risk, but without diabetes, were randomly assigned to a target systolic blood pressure of <120 mmHg (intensive treatment) or a target of <140 mmHg (standard treatment). A significantly lower rate of the primary composite outcome and all-cause mortality in the intensive-treatment group than in the standard-treatment group was observed. Summaries and overviews of the late-breaking trials, clinical science special report sessions, and sessions to which members of the Japanese Circulation Society contributed are presented.

Report of the American Heart Association (AHA) Scientific Sessions 2014, Chicago

The American Heart Association (AHA) Scientific Sessions were held in Chicago on November 15-19, 2014. The meeting attracted more than 17,000 participants, including physicians, research scientists, students, and paramedical personnel, from more than 100 countries. Sessions over the 5 days included comprehensive and unparalleled education delivered via more than 5,000 presentations, with 1,000 invited faculty members and 4,000 abstract presentations from world leaders in cardiovascular (CV) disease. There were 16 trials scheduled in 4 late-breaking clinical trial sessions. The Dual Antiplatelet Therapy study revealed that aspirin plus a thienopyridine beyond 1 year subsequent to placement of a drug-eluting stent, as compared with aspirin therapy alone, significantly reduced stent thrombosis and major CV and cerebrovascular events but was associated with increased risk of bleeding. The IMPROVE-IT research showed that, relative to simvastatin with placebo, simvastatin with 10 mg of ezetimibe daily led to a significantly lower primary combined endpoint in moderate- to high-risk patients, who stabilized following acute coronary syndrome. This was the first trial to demonstrate incremental clinical benefit by adding a nonstatin agent to statin therapy and reaffirmed the low-density lipoprotein (LDL) hypothesis stating that reducing LDL-cholesterol prevents CV events. Summaries and overviews of both the late-breaking trials and the sessions to which members of the Japanese Circulation Society contributed are presented.

Report of the American College of Cardiology (ACC) Scientific Sessions 2014, Washington, DC

The American College of Cardiology (ACC) Scientific Session was held at the Walter E. Washington Convention Center in Washington, DC from March 29-31, 2014. The ACC Scientific Session is one of 3 major scientific cardiology meetings in the world, with over 20,000 attendees from 109 countries. There were over 2,200 oral and poster abstracts, and 22 late-breaking clinical trials (LBCTs), which are the focus of this report. Interestingly, in the CoreValve trials, transcatheter aortic valve replacement with a self-expanding transcatheter aortic-valve bioprosthesis was associated with a higher survival rate at 1 year than surgical aortic valve replacement. Long-term results in a further study are needed. I hope the present report will encourage others to attend the ACC Scientific Session 2015 to be held in San Diego on March 14-16, 2015.
