Coronary Sinus Reducer Implantation Improves Chronic Refractory Angina
A recent study published in the Journal of American College of Cardiology found that implantation of the coronary sinus Reducer is safe and is associated with a reduction of anginal symptoms and improvement of quality of life in patients with refractory angina who were not candidates for further revascularization.

Prior Silent MI Is Associated with Worse Outcomes in Patients with AMI
A recent observational longitudinal study published in the Journal of American College of Cardiology showed that previous silent myocardial infarction (MI) was found in 8.2% of patients presenting with first acute myocardial infarction (AMI). Previous silent MI was detected by late gadolinium enhancement- cardiac magnetic resonance (LGE-CMR). Continue reading
Acute Myocardial Infarction after Laboratory-Confirmed Influenza Infection
In a recent retrospective cohort study published in the New England Journal Medicine, a significant association was found between acute respiratory infections, particularly influenza, and the occurrence of acute myocardial infarction (MI) in the following week. The study also highlights the increased risk in older patients and in those who are hospitalized for the first time for an MI. Continue reading
S-LAAO Reduces Thromboembolism in AFib Patients After Heart Surgery
In a recent retrospective cohort study published in the Journal of American Medical Association conducted on patients with atrial fibrillation (AF) undergoing cardiac surgery, surgical left atrial appendage occlusion (S-LAAO) as compared with no surgical left atrial appendage occlusion (no S-LAAO) was significantly associated with lower risk of readmission for thromboembolism.

Mortality in PCI Patients With Incomplete Revascularization
In a recent retrospective observational study published in JAMA Cardiology, patients that underwent percutaneous coronary interventions with incomplete revascularization were at higher risk of mortality if they had at least 90% stenosis in an incompletely revascularized vessel, incomplete revascularization in 2 or more vessels, or proximal left anterior descending artery incomplete revascularization.
