AI helps to predict risk of a potentially fatal heart disease

reprint An artificial intelligence algorithm is able to identify a patient’s risk from a cholesterol-raising genetic condition that has a 20-fold increased risk of coronary artery disease if untreated. Individuals with the potentially fatal heart disease—called familial hypercholesterolemia (FH)—carry a mutation that interferes with their bodies’ ability to clear low-density Czytaj więcej…

Quick Take: Effect of a Multifaceted Quality Improvement Intervention on the Prescription of Evidence-Based Treatment in Patients at High Cardiovascular Risk in Brazil

In low and middle-income countries, the implementation of evidence-based therapies for cardiovascular disease, including the use of statins, antiplatelet therapy and anti-hypertensive medications, remains a challenge, despite high associated morbidity and mortality. In this cluster randomized controlled trial, 1619 patients with established atherosclerotic disease from 40 public and private outpatient Czytaj więcej…

#VisualAbstract: Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients

1. This randomized control trial compared post-surgical outcomes between transcatheter aortic-valve replacement (TAVR) with balloon-expandable valves or surgical valve replacement in low- risk surgical patients, finding that patients randomized to receive TAVR had significantly lower rates of composite death, stroke or rehospitalization after one year. 2. Patients randomized to the Czytaj więcej…

Catheter-based renal denervation reduces blood pressure in patients with uncontrolled hypertension

1. Meta-analysis of sham-controlled randomized trials of catheter-based renal denervation demonstrated reduction in ambulatory and office systolic blood pressures. 2. Second-generation trials demonstrated greater reduction in ambulatory systolic blood pressure compared to first generation trials. Evidence Rating Level: 1 (Excellent) Study Rundown: Hypertension is one of the most common adult Czytaj więcej…

Chinese population study shows high prevalence of elevated cardiovascular disease risk and low utilization of pharmacotherapy

1. In this national screening project, around 10% of middle-aged Chinese subjects were found to be at “high risk” for cardiovascular disease. 2. Aspirin and statins were only used by 0.6% and 2.4% of high-risk individuals, respectively. Evidence Rating Level: 3 (Average) Study Rundown: A 2015 study showed that cardiovascular Czytaj więcej…

3D-imaging tool first to provide inside view of capillaries

reprint Researchers at Northwestern University have developed new technology that provides images of the tiny, hair-like blood vessels in the human body. Called spectral contrast optical coherence tomography angiography (SC-OCTA), the non-invasive 3D-imaging tool can measure blood flow and oxygen exchange in microscopic capillaries, providing early diagnosis of diseases. “There Czytaj więcej…

AI-enabled EKG proves powerful screening tool for heart disease

reprint Researchers at the Mayo Clinic have applied artificial intelligence to a routine method of measuring the heart’s electrical activity to identify patients with asymptomatic left ventricular dysfunction. According to Mayo officials, until now there hasn’t been an inexpensive, noninvasive, painless screening tool for asymptomatic left ventricular dysfunction—a precursor to Czytaj więcej…
