Low concordance between troponin assays for ACS
March 25, 2021
Concordance between high-sensitivity troponin assays was only 37% for a single blood draw, rising to 75% with serial testing, but still changing management decisions in some patients.
Heart failure redefined with new classifications, staging
March 8, 2021
Heart failure terminology gets a landmark reno, with a new universal definition, revised stages of development and progression, and updated LVEF classifications.
New-onset arrhythmias low in COVID-19 and flu
February 26, 2021
Overall, incidence of AF/AFL and new onset AF/AFL was similar in COVID-19 vs. influenza. Mortality in those with arrhythmias also increased to a similar extent in both diseases.
Myocardial injury seen on MRI in 54% of recovered COVID-19 patients
February 25, 2021
Two months after discharge, 54% of hospitalized COVID-19 patients with troponin elevation showed signs of myocardial injury on MRI, some of which was likely pre-existing, the authors say.
Microthrombi, necrosis seen in COVID-19 hearts on autopsy
February 3, 2021
A new autopsy series shows microthrombi and focal necrosis in hearts of patients who died of COVID-19. The findings support use of anticoagulation, but best dosing remains unclear, researchers say.
CVD deaths rose, imaging declined during pandemic
January 14, 2021
Two new papers quantify the impact of COVID-19 on patients with heart disease: more deaths, less disease testing or diagnosis. Experts suggest shutdowns may have been too complete.
COVID-19 mortality in hospitalized HF patients: Nearly 1 in 4
December 31, 2020
In-hospital mortality was 24.2% for patients with HF hospitalized with COVID-19, as compared with 14.2% for individuals without HF who were hospitalized with COVID-19.
NETs a possible therapeutic target for COVID-19 thrombosis?
December 31, 2020
Small study, but may provide insight regarding COVID-19 patients who experience acute STEMI.
Myocarditis rare, macrophage infiltration common at COVID autopsy
November 18, 2020
An autopsy study shows myocarditis is uncommon, seen in only 14% of COVID-19 deaths, but macrophage infiltration is very common and might explain cardiac imaging findings from earlier studies.
Observational study again suggests lasting impact of COVID-19 on heart
September 21, 2020
Cardiac MR study raises concern for myocarditis post COVID in some young athletes, but commentators suggest these and other such findings are too weak to suggest routine screening with CMR.
