Ticagrelor therapy, without aspirin, can benefit patients with acute coronary syndrome

Patients with acute coronary syndrome (ACS) who stopped taking aspirin three months after the insertion of a coronary stent and then took the anti-platelet medication ticagrelor alone for nine months had fewer episodes of bleeding and no increase in heart attacks, stroke or other adverse events caused by blockages in the arteries, compared with patients who took both aspirin and ticagrelor for a year.

Taking ticagrelor alone better for patients with complex heart disease

Patients with complex heart disease who stopped taking aspirin three months after the insertion of one or more coronary stents and then took the anti-platelet medication ticagrelor alone for a year had fewer episodes of bleeding and no increase in heart attacks, stroke or other adverse events caused by blockages in the arteries, compared with patients who took both aspirin and ticagrelor over the same period.

10-year follow-up study shows safety, efficacy of stenting compared with bypass surgery

In a study with the longest follow-up to date of patients with a high-risk form of heart disease known as left main coronary artery disease (LMCAD), researchers found no significant differences in rates of death, heart attack or stroke between patients who were treated with a stent and those who underwent heart bypass surgery.

Treatment with ticagrelor alone reduces adverse events in patients with diabetes

Patients with diabetes who stopped taking aspirin three months after the insertion of a coronary stent and then took the anti-platelet medication ticagrelor alone for a year had fewer episodes of bleeding and no increase in heart attacks, stroke or other adverse events caused by blockages in the arteries, compared with patients who took both aspirin and ticagrelor for a year.

Revita DMR therapy has potential to transform lives of patients with poorly controlled type 2 diabetes

Patients with poorly controlled type 2 diabetes who underwent a novel, minimally invasive, endoscopic procedure called Revita duodenal mucosal resurfacing had significantly improved blood glucose (sugar) levels, liver insulin sensitivity, and other metabolic measures three months later, according to new data from the REVITA-2 study.

Renal denervation effective in patients with untreated high blood pressure

Three months after undergoing renal denervation —a procedure that delivers energy to overactive nerves leading to the kidney to decrease their activity—patients with untreated high blood pressure had statistically significant reductions in average blood pressure over 24 hours compared with patients who underwent a sham procedure and experienced no major adverse effects, according to results from the SPYRAL-HTN OFF MED pivotal trial presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

Heart size of dogs affects both vortex flow and pressure difference

An international collaboration led by veterinary scientists at Tokyo University of Agriculture and Technology, Japan, has found that size of a dog heart affects both vortex flow and pressure difference in the heart, which both are promising as an index of diastolic function.

Outcomes of mothers giving birth during COVID-19 pandemic

Researchers from Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China have looked at the outcomes of pregnant mothers with COVID-19 and their newborns. Their study titled, “Clinical features and obstetric and neonatal outcomes of pregnant patients with COVID-19 in Wuhan, China: a retrospective, single-center, descriptive study” was published in the latest issue of the journal The Lancet, Infectious Diseases.

Researchers use ultrasound technique to accurately localize cardiac arrhythmias

Cardiac arrhythmias are a major cause of morbidity and mortality worldwide. Currently, the 12-lead electrocardiogram is the noninvasive clinical gold standard used to diagnose and localize these conditions, but it has limited accuracy, cannot provide an anatomical tool to visually localize the source of the arrhythmia, and depending on which clinician is looking at the signals, there might be some interpretation variability.

New immunotherapeutic strategy shows promise to fight off infectious biofilms

The same way baking soda breaks down grease and grime, making surfaces easier to clean, researchers at the Lewis Katz School of Medicine at Temple University now show that a new therapeutic molecule can break apart communities of harmful bacteria, opening the way for bacteria-killing antibiotics to more effectively clear out infections.
