Transcatheter aortic valve implantation (TAVI) offers an effective, less invasive therapeutic alternative to surgical aortic valve replacement in patients with symptomatic, severe aortic stenosis. Although TAVI is demonstrated to be superior to medical therapy or surgery in patients who are at prohibitive or high risk for aortic valve surgery, less is known about TAVI in patients who are at low risk for complications or death from surgery. At EuroPCR 2021, Dr J Forrest will present the complete 2-year follow-up from the Evolut low risk trial.

Results of the interim analyses performed after 12 months in the first 111 patients enrolled in phase II Cool AMI trial evaluating safety and effectiveness of systemic therapeutic hypothermia as an adjunctive therapy in anterior STEMI undergoing PCI as compared to PCI only. Analyses showed significant differences among treatment groups, including longer randomization-to-balloon time and total ischemic time in treatment arm, justifying premature trial discontinuation.

The ISCHEMIA trial found no significant difference between an invasive vs. a conservative strategy in patients with chronic coronary syndromes and moderate to severe ischemia at a mean of 3.2 years. However, the cumulative difference in the estimates of cardiac death between the invasive and conservative strategies tended to increase numerically over time (e.g., 0.3% in favor of the invasive strategy at 2 years and 1.3% at 5 years). Because the ISCHEMIA trial was not powered for cardiac mortality and did not focus on long-term follow-up, the rationale for a meta-analysis emerged.

ATLANTA - MAY 18, 2021 - A new study finds breast cancer survivors in general have higher risk of new cancer diagnosis compared to healthy individuals. The article, which appears in CANCER, states that compared to the general population in the United States, the risk of new cancer diagnoses among survivors was 20% higher for those with hormone receptor (HR) positive cancers and 44% higher for those with HR-negative cancers.

An international research team headed by Michal Hocek of the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague) and Charles University and Ciara K. O'Sullivan of Universitat Rovira i Virgili (URV) in Spain have developed a novel method for labeling DNA, which in the future can be used for sequencing DNA by means of electrochemical detection. The researchers presented their results in the Journal of the American Chemical Society.

A rigorous meta-analysis of randomized clinical trials (RCTs) that compared the effects of medical therapies alone with medical therapies plus revascularization in patients with stable ischemic heart disease (SIHD) was presented at EuroPCR on May 18, 2021. The study concluded that adding revascularization was associated with a statistically important reduction in cardiovascular death associated with a statistically important reduction in spontaneous myocardial infarction (MI), providing a biologically plausible explanation for the observed benefit.

A new technology developed by UZH researchers enables the body to produce therapeutic agents on demand at the exact location where they are needed. The innovation could reduce the side effects of cancer therapy and may hold the solution to better delivery of Covid-related therapies directly to the lungs.

BOSTON - Peripheral artery disease (PAD), or blockages in the arteries outside of the heart, affects more than 200 million people worldwide and 12.5 million people in the United States. Patients with this circulatory disorder may develop severe leg pain or unhealing wounds that require a minimally invasive revascularization procedure to open the blood vessels to improve blood flow.

Early preterm births may be dramatically decreased with docosahexaenoic acid (DHA) supplements, with a dose of 1000 mg more effective for pregnant women with low DHA levels than the 200 mg found in some prenatal supplements, according to a study led by researchers from the University of Kansas and the University of Cincinnati and published today in EClinicalMedicine, a clinical journal of The Lancet.

Two months after undergoing renal denervation (RDN), patients with high blood pressure who did not respond to treatment with multiple medications had a greater reduction in daytime systolic blood pressure than patients who did not receive RDN, with no difference in major adverse effects, according to research presented at the American College of Cardiology's 70th Annual Scientific Session.

Clopidogrel outperformed aspirin in what is believed to be the first and largest randomized trial to compare the effectiveness of the two antiplatelet drugs as long-term maintenance therapy for patients who had no adverse events after one year of dual antiplatelet therapy (DAPT) following the insertion of a coronary stent. After two years of follow-up, chronic maintenance therapy with clopidogrel resulted in a 30% reduction in deaths, heart attacks, strokes or major bleeding events, according to research presented at the American College of Cardiology's 70th Annual Scientific Session.

Among patients who had a cardiac stent inserted after a heart attack, switching to less-potent dual antiplatelet therapy (DAPT) after 30 days was safer and more effective in preventing adverse events a year later than continuing on a high-potency DAPT regimen, according to data presented at the American College of Cardiology's 70th Annual Scientific Session.

Taking medications to protect the heart from damage associated with adjuvant breast cancer therapy--medications that are administered in addition to surgery to remove a tumor--did not significantly improve markers of heart health two years after breast cancer treatment, according to a study presented at the American College of Cardiology's 70th Annual Scientific Session.

What The Study Did: Online search data were used to assess changes in home birth information seeking across the United States and United Kingdom during the COVID-19 pandemic.

Oncotarget published "Phase 1 study of Z-Endoxifen in patients with advanced gynecologic, desmoid, and hormone receptor-positive solid tumors" which reported that Z-endoxifen administration was anticipated to bypass these variations, increasing active drug levels, and potentially benefiting patients responding sub-optimally to tamoxifen.
