Spontaneous coronary artery dissection (SCAD) has gained considerable recognition as an important cause of acute myocardial infarction (AMI), particularly among young females without conventional cardiovascular risk factors.  To facilitate dissemination of current knowledge on SCAD, a Scientific Statement from the American Heart Association was recently published in Circulation by Hayes et al. concerning the current knowledge of epidemiology, precipitants and triggers, pathophysiology, and associated comorbidities.  Furthermore, the document provides an overview of the advance in diagnostic imaging, management options, as well as the prognostic outlook for SCAD, in hopes of spurring a paradigm shift in the care of this under-diagnosed condition.

In a recent study published in The Lancet, it has been found that the magnitude of reduction in C Reactive Protein (CRP) levels due to treatment with Canakinumab, an interleukin 1β targeting monoclonal antibody, may directly correlate with a decrease in major cardiovascular events in post-myocardial infarction (MI) patients, even in the absence of an alteration in LDL levels.

In a recent study published in the New England Journal of Medicine, it was found that endovascular thrombectomy for ischemic stroke that is performed 6 to 16 hours after the onset of symptoms resulted in better functional outcomes than standard medical therapy alone among patients with a proximal middle cerebral artery or internal carotid artery occlusion.

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.

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.  Continue reading →

According to a recently published article in Circulation, it was found that D-dimer level is an independent predictor of the long-term (up to 16 years) risk of arterial and venous events, cause-specific mortality, and the incidence of new cancers. The results of the study are based on a  subanalysis of the LIPID trial. Continue reading →

With the increasing use and the legalization of marijuana in several states of USA, there is a need to evaluate its impact on the health. To explore this, a systematic review was recently published in Annals of Internal Medicine by Ravi et al. In the study, the investigators studied the association between marijuana use and cardiovascular outcomes. The authors concluded, “Evidence examining the effect of marijuana on cardiovascular risk factors and outcomes, including stroke and myocardial infarction, is insufficient”. Continue reading →

A systematic review and meta-analysis recently published in the journal, Circulation, showed a strong association between computed tomographic coronary angiography (CTCA) defined high risk plaque (HRP) features and major adverse cardiovascular events (MACE) in patients with suspected coronary artery disease (CAD).

In a recent meta-analysis published in the Journal of the American College of Cardiology, it was found that postoperative complications of Transcatheter Aortic Valve Replacement (TAVR) were different between males and females. While females were at increased risk of short-term complications (within 30 days) such as bleeding, stroke, and vascular complications, they had a lower incidence all-cause mortality within one year of the procedure.

The use of mechanically expandable valves was not inferior to self-expandable valves in high risk patients with severe aortic stenosis enrolled in the REPRISE III clinical trial. The trial results support the potential for the first generation LOTUS valve to become part of regular clinical practice. Continue reading →

In a recent analysis published in the Journal of the American College of Cardiology, a link between silent myocardial infarction and subsequent heart failure has been demonstrated, revealing a novel potential marker for heart failure. Continue reading →

The assessment of left atrial reservoir strain and P-wave to A’ duration on tissue Doppler imaging provides additional risk stratification for stroke after initial CHA₂DS₂-VASc scoring, according to a study published in the European Heart Journal, and may prove helpful in guiding decisions about anticoagulation for patients after the diagnosis of atrial fibrillation.

The use of MRI resulted in no long-term clinically significant adverse events in patients with legacy cardiac devices and only 1 in 200 patients experienced a power-on reset of the cardiac device, according to a recent publication in the New England Journal of Medicine. Continue reading →

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.
